the fixing part comprises a limiting part-1, a fixing part-2, a fixing part body-201, a buckling part-202, a limiting component-3, a base plate-10, a through hole-11, a first surface-12, a limiting part-20, a sub-limiting part-21, a smooth surface-22, a rough surface-23, a first positioning part-24, a second positioning part-25, an elastic part-30, a connecting part-40, an avoiding groove-41 and an elastic part-50.

Detailed Description

The following is a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.

Before the technical solutions of the present application are introduced, the technical problems in the related art will be described in detail.

In the related art, particularly in the field of mechanical structure assembly, it is often necessary to connect a plurality of components together. The fixing member can be used to connect the substrate and the connecting member together. The first housing and the second housing may be connected together by screwing the first housing and the second housing together, for example. However, during the detachment process, after the screw is detached from the second housing, the screw is free to move, so that the screw is easily dropped from the through hole in the first housing. Particularly, when the device is used at high altitude, the removed screw is easy to fall and lose, a user needs to unscrew the screw with one hand and then hold the screw with the other hand, and potential safety hazards exist.

At present, the E-shaped buckle is additionally arranged by people, and the E-shaped buckle is arranged on a screw clamping groove which penetrates through the through hole, so that after the screw and the second shell are disassembled, the screw is fixed on the base plate under the action of the E-shaped buckle, and the screw is prevented from falling out. However, the E-shaped buckle needs to be additionally assembled, the screw needs to be designed and processed with the clamping groove, and the part cost and the assembling working hour are increased.

In view of the above, please refer to fig. 1-4 to solve the above problem. Fig. 1 is a schematic structural diagram of a limiting element according to an embodiment of the present application. Fig. 2 is a schematic view of the fastener just after it has entered the through hole. Fig. 3 is a schematic view of the fixing member penetrating through the through hole. Fig. 4 is a schematic view of the fixing member after penetrating through the through hole. The present embodiment provides a stopper 1. The position-limiting member 1 includes a substrate 10 and a position-limiting portion 20. The substrate 10 is provided with a through hole 11. The limiting part 20 is mounted on the substrate 10, at least a part of the orthographic projection of the limiting part 20 on the substrate 10 is located in the through hole 11, at least a part of the limiting part 20 can rotate along a direction perpendicular to the surface of the substrate 10 with the through hole 11, and the limiting part 20 is used for limiting the fixing part 2 penetrating through the through hole 11.

The substrate 10 provided in the present application may be a component in any structural form, and the present application does not limit the present application. The substrate 10 only needs to be provided with a through hole 11, and the through hole 11 is used for the fixing member 2 to penetrate through. In the related art, the fixing member 2 and the substrate 10 are limited by additionally adding an E-shaped buckle. In the present application, the limiting portion 20 may be additionally disposed on the substrate 10, such that the limiting portion 20 is directly disposed on the substrate 10, and at least a portion of the orthographic projection of the limiting portion 20 on the substrate 10 is located in the through hole 11, that is, the limiting portion 20 occupies at least a portion of the through hole 11. As for the specific structure of the limiting portion 20 mounted on the substrate 10, the present application will be described in detail below. The application can also make at least part of the limiting part 20 rotate along the direction vertical to the surface of the substrate 10 provided with the through hole 11, so that the limiting part 20 can expand or contract, and the size of the area without the limiting part 20 in the through hole 11 is increased or reduced. Alternatively, the surface of the substrate 10 provided with the through hole 11 may be understood as the first surface 12, and the first surface 12 will be described later in this application.

The present application may then provide a fixture 2, the fixture 2 including, but not limited to, a screw. The radial dimension of the partial region structure of the fixing member 2 (the dimension represented by D1 in fig. 2) is larger than the dimension of the region of the through-hole 11 where the stopper portion 20 is not provided (the dimension represented by D2 in fig. 2). While the radial dimension of the remaining part region structure of the fixing 2 is smaller than D1. And the radial dimension of the fixing member 2 is smaller than the dimension of the through hole 11 (dimension represented by D in fig. 2) so that the fixing member 2 can pass through the through hole 11. As shown in fig. 2, when the fixing member 2 starts to enter the through hole 11, the stopper portion 20 is not yet contacted at this time, and thus the fixing member can freely move in the through hole 11. As shown in FIG. 3, when the fixture 2 comes into contact with the stopper 20, the stopper 20 is rotated in the direction of the thrust (the direction in which the fixture 2 penetrates) by the thrust of the fixture 2, so that D2 is increased, and D2 ≧ D1 for the fixture 2 to pass through. As shown in FIG. 4, after the part of the fixing member 2 having a larger radial dimension passes through the stopper portion 20, the stopper portion 20 is rotated in the opposite direction, so that the stopper portion 20 is restored to continue to have D2 < D1. When the fixing member 2 falls, the position-limiting portion 20 abuts against the fixing member 2, thereby preventing the fixing member 2 from falling from the through hole 11 and improving the position-limiting effect of the substrate 10. In addition, the limiting part 20 is arranged on the substrate 10, so that the process operation for assembly can be simplified, the number of parts and the processing cost are reduced, and the assembly time is saved.

Optionally, the extending direction of the limiting portion 20 may be parallel to the first surface 12 when the limiting portion is not under stress, or may form a certain included angle with the surface, so that the sidewall surface of the limiting portion 20 is inclined to provide a guiding function. The present embodiment is illustrated with the limiting portion 20 having a certain angle with the surface.

Please refer to fig. 5-6 together. Fig. 5 is a schematic structural diagram of a limiting element according to another embodiment of the present application. Fig. 6 is a schematic structural diagram of a limiting element according to another embodiment of the present application. In the present embodiment, an orthographic projection of the stopper portion 20 on the substrate 10 covers the through hole 11.

In the present embodiment, the orthographic projection of the limiting portion 20 on the substrate 10 may cover the through hole 11, or the limiting portion 20 may completely cover the through hole 11, so that the substrate 10 may be applied to fixing members 2 of various sizes, that is, the fixing members 2 of various sizes may limit the fixing members 2 by rotating the limiting portion 20 when penetrating through the through hole 11. Alternatively, the number of the position limiting portions 20 may be one (as shown in fig. 5), and the through hole 11 is directly covered by one position limiting portion 20. Alternatively, the number of the limiting portions 20 is plural, that is, the limiting portion 20 includes a plurality of sub-limiting portions 21 (as shown in fig. 6), the plurality of sub-limiting portions 21 are disposed corresponding to the periphery of the through hole 11, and the plurality of sub-limiting portions 21 are mutually matched to make the orthographic projection of the plurality of sub-limiting portions 21 on the substrate 10 cover the through hole 11.

The above description describes the stop portion 20 as being rotatable relative to the first surface 12. This embodiment provides two implementations. Please refer to fig. 7, fig. 7 is a schematic structural diagram of a position limiting element according to another embodiment of the present application. In the present embodiment, the stopper portion 20 has elasticity. Alternatively, the limiting member 1 further includes an elastic portion 30, and the elastic portion 30 connects the substrate 10 and the limiting portion 20.

In one implementation, the limiting portion 20 may have elasticity, so that the limiting portion 20 itself can rotate after receiving an external force, and the limiting portion 20 can automatically reset after the external force is removed. Alternatively, the stopper portion 20 may be bonded to the substrate 10. In another implementation, as shown in fig. 7, the elastic portion 30 may be added to connect the substrate 10 and the stopper portion 20 to each other. The elastic portion 30 is used to rotate the entire stopper portion 20 around the elastic portion 30.

Please refer to fig. 8, fig. 8 is a schematic structural diagram of a position limiting element according to another embodiment of the present application. In the present embodiment, when the position limiting portion 20 has elasticity, the thickness of the position limiting portion 20 away from the substrate 10 is smaller than the thickness of the position limiting portion 20 close to the substrate 10.

Compared with the limiting part 20 close to the substrate 10, the limiting part 20 far away from the substrate 10 is more likely to contact with the fixing part 2 so as to receive the force of the fixing part 2 to rotate the limiting part 20. Therefore, when the limiting part 20 has elasticity, the thickness of the limiting part 20 far away from the substrate 10 can be smaller than the thickness of the limiting part 20 close to the substrate 10, namely, the thickness of the limiting part 20 far away from the substrate 10 is smaller, so that when the fixing part 2 penetrates through the through hole 11, the limiting part 20 can be rotated more easily. Optionally, the thickness of the limiting portion 20 gradually increases from the direction away from the substrate 10 to the direction close to the substrate 10.

The above description describes that the limiting portion 20 is directly mounted on the substrate 10, and the present application provides two implementation manners. Please refer to fig. 9, fig. 9 is a schematic structural diagram of a position limiting element according to another embodiment of the present application. In the present embodiment, the stopper portion 20 is provided on the surface of the substrate 10 on which the through hole 11 is opened, and the stopper portion 20 extends in a direction toward the through hole 11.

In one implementation manner, the position-limiting portion 20 may be directly disposed on the first surface 12, and the position-limiting portion 20 is extended toward the center of the through hole 11, so that an orthographic projection of the position-limiting portion 20 on the substrate 10 may be located in the through hole 11, thereby achieving the position-limiting effect. Alternatively, the stopper portion 20 may be disposed directly corresponding to the periphery of the through-hole 11 and adjacent to the through-hole 11 (as shown in fig. 1), thereby reducing the size of the stopper portion 20.

Please refer to fig. 10, fig. 10 is a schematic structural diagram of a position limiting element according to another embodiment of the present application. In this embodiment, the limiting portion 20 is disposed on a hole wall of the through hole 11 surrounded by the substrate 10.

In another embodiment, the position-limiting part 20 may be directly disposed on the hole wall of the substrate 10 surrounding the through hole 11. In the process of matching the fixing member 2, the limiting member 1 and the connecting member 40, the connecting member 40 can be connected to the substrate 10 of the limiting member 1 through the fixing member 2. In the embodiment, the limiting portion 20 is disposed on the controller, so that the size of the limiting portion 20 protruding from the first surface 12 can be reduced, and the connection performance between the connection member 40 and the substrate 10 can be improved.

Referring to fig. 10 again, in the present embodiment, a distance is formed between one end of the limiting portion 20 away from the hole wall and the surface of the substrate 10 on which the through hole 11 is formed.

In the present embodiment, on the basis that the position-limiting portion 20 is disposed on the hole wall, a distance may be provided between one end of the position-limiting portion 20 away from the hole wall and the surface of the substrate 10 on which the through hole 11 is formed. It can also be understood that an end of the position-limiting portion 20 away from the hole wall is spaced from the first surface 12 in any state, i.e. no matter how the position-limiting portion 20 rotates, so that it is ensured that the position-limiting portion 20 does not protrude from the first surface 12, thereby solving the problem that the connecting member 40 cannot be tightly connected to the substrate 10 due to the protrusion of the position-limiting portion 20 from the first surface 12.

Please refer to fig. 11, fig. 11 is a schematic structural diagram of a position limiting element according to another embodiment of the present application. In this embodiment, one end of the limiting portion 20 away from the substrate 10 has a rounded structure.

This embodiment can make spacing portion 20 deviate from the one end of base plate 10 has round chamfer structure, and the frictional force between reducible spacing portion 20 and mounting 2 like this can make mounting 2 install and dismantle more easily on the one hand, and on the other hand still can avoid spacing portion 20 to deviate from the one end of base plate 10 too sharply and thus easily to make and take place to damage between spacing portion 20 and the mounting 2.

Please refer to fig. 12, fig. 12 is a schematic structural diagram of a position limiting element according to another embodiment of the present application. In the present embodiment, one side surface of the stopper portion 20 is a smooth surface 22, and the other side surface of the stopper portion 20 opposite to the smooth surface is a rough surface 23.

In this embodiment, one side surface of the stopper portion 20 may be a smooth surface 22, and the other side surface of the stopper portion 20 opposite to the smooth surface 23. Alternatively, the present embodiment may make one side surface of the stopper portion 20, which is close to the fixing member 2 and penetrates therethrough, a smooth surface 22, and make the other opposite side surface a rough surface 23. Since the fixing member 2 is smoothly close to the side through which the fixing member 2 passes when the fixing member 2 passes through the through hole 11, when the fixing member 2 comes into contact with the smooth surface 22, the frictional force between the fixing member 2 and the stopper portion 20 can be reduced to make the mounting of the fixing member 2 easier. In addition, after the fixing member 2 penetrates through the through hole 11, the fixing member 2 can be in contact with the rough surface 23, so that the friction force between the fixing member 2 and the limiting part 20 is improved, and the limiting effect of the limiting part 20 is improved.

Please refer to fig. 13, and fig. 13 is a schematic structural diagram of a limiting element and a fixing element according to an embodiment of the present application. In this embodiment, one end of the limiting portion 20 away from the substrate 10 is provided with a first positioning portion 24, and the first positioning portion 24 is used for cooperating with a second positioning portion 25 of the fixing member 2 to fix the fixing member 2.

In this embodiment, a first positioning portion 24 may be disposed at an end of the limiting portion 20 away from the substrate 10, and a second positioning portion 25 is disposed on the fixing element 2, so that the limiting effect between the fixing element 2 and the limiting portion 20 is further improved by the cooperation of the first positioning portion 24 and the second positioning portion 25. Alternatively, the first positioning portion 24 may be a convex column or a groove, and the second positioning portion 25 may be a groove or a convex column. It can also be understood that when the first positioning portion 24 is a convex column, the second positioning portion 25 is a groove (as shown in fig. 13). When the first positioning portion 24 is a groove, the second positioning portion 25 is a groove. In the present embodiment, only the first positioning portion 24 is a convex column, and the second positioning portion 25 is a concave groove. As shown in fig. 13, when the fixing element 2 penetrates the through hole 11, the position-limiting portion 20 can rotate, so that the first positioning portion 24 does not affect the movement of the fixing element 2, but after the fixing element 2 penetrates, the first positioning portion 24 can enter the second positioning portion 25 in the process of the fixing element 2 falling, thereby improving the connection performance between the fixing element 2 and the position-limiting portion 20. Alternatively, the partially disassembled direction in the extending direction of the first positioning portion 24 and the second positioning portion 25 is the same as the penetrating direction of the fixing member 2.

Referring to fig. 14, fig. 14 is an exploded view of a position limiting assembly according to an embodiment of the present disclosure. The embodiment provides a limiting assembly 3, the limiting assembly 3 includes a fixing member 2 and a limiting member 1 provided as the above embodiment of the present application, the fixing member 2 penetrates through the through hole 11, and the radial dimension of the portion of the fixing member 2 penetrating through the through hole 11 is greater than the dimension of the region, in which the limiting portion 20 is not provided, in the through hole 11.

The limiting assembly 3 provided by the present embodiment includes a limiting member 1 and a fixing member 2, which are matched to form the limiting assembly 3. By adopting the stopper 1 provided in the above-mentioned embodiment of the present application, the radial dimension (as represented by D1 in fig. 14) of the partial region structure of the fixing member 2 is larger than the dimension (as represented by D2 in fig. 14) of the region where the stopper portion 20 is not provided in the through hole 11. While the radial dimension of the remaining part region structure of the fixing 2 is smaller than D1. And the radial dimension of the fixing member 2 is smaller than the dimension of the through hole 11 (dimension represented by D in fig. 14) so that the fixing member 2 can pass through the through hole 11. When the portion penetrates the through hole 11, the stopper portion 20 rotates to expand, and when the portion penetrates the through hole 11, the stopper portion 20 rotates to restore, and the stopper portion 20 abuts against the fixing member 2, thereby preventing the fixing member 2 from falling out of the through hole 11. As for the specific limiting process and principle, the present application has been introduced above, and is not described herein again. The limiting assembly 3 provided by the embodiment improves the limiting effect of the substrate 10, and improves the connection performance between the substrate 10 and the limiting member 1 in the limiting assembly 3. In addition, the limiting part 20 is arranged on the substrate 10, so that the process operation for assembly can be simplified, the number of parts and the processing cost are reduced, and the assembly time is saved.

Please refer to fig. 15, fig. 15 is an exploded view of a position limiting assembly according to another embodiment of the present disclosure. In this embodiment, the fixing element 2 includes a fixing element body 201 and a fastening portion 202 protruding from a peripheral surface of a portion of the fixing element body 201, and the fastening portion 202 is matched with the fixing element body 201 so that a radial dimension of the portion of the fixing element 2 penetrating through the through hole 11 is larger than a dimension of an area of the through hole 11 where the limiting portion 20 is not disposed.

The above mentioned matters mention that the size of the structure of the partial region of the fixing member 2 is larger than the size of the region of the through hole 11 where the position-limiting part 20 is not provided. In the present embodiment, the fixing element 2 includes a fixing element body 201 and a fastening portion 202, and the fastening portion 202 is engaged with the fixing element body 201, so that the radial dimension of the fixing element 2 penetrating through the through hole 11 is larger than the dimension of the region of the through hole 11 where the stopper portion 20 is not provided. It is also understood that the size of the portion provided with the locking portion 202 is larger than the size of the region of the through hole 11 where the stopper portion 20 is not provided. As for the size of the fixing member body 201, the size may be larger than the size of the region where the limiting portion 20 is not disposed in the through hole 11, or may be smaller than the size of the region where the limiting portion 20 is not disposed in the through hole 11. In addition, the fastening portion 202 is not only used for fastening with the limiting portion 20, but also used for connecting the connecting member 40 with the fastening portion 202.

Alternatively, the fixing member 2 includes, but is not limited to, a screw including a stud and an external thread protruded on a peripheral surface of the stud portion. The stud is the fixing member body 201, and the external thread is the fastening portion 202. The connecting member 40 is provided with an internal thread for screw-coupling with the external thread.

Referring to fig. 13 again, in the present embodiment, the fastening portion 202 is provided with a second positioning portion 25, and the second positioning portion 25 is used for cooperating with the first positioning portion 24 of the limiting member 1 to connect the limiting portion 20 to the fastening portion 202.

In this embodiment, the buckling portion 202 may further include a second positioning portion 25, and one end of the limiting portion 20 away from the substrate 10 includes a first positioning portion 24, so that the limiting portion 20 is connected to the buckling portion 202 by the cooperation of the first positioning portion 24 and the second positioning portion 25. As for the specific structure of the first positioning portion 24 and the second positioning portion 25, the detailed description is provided above, and the detailed description is not limited herein.

Please refer to fig. 16, fig. 16 is an exploded view of a position limiting assembly according to another embodiment of the present disclosure. In this embodiment, the limiting assembly 3 further includes a connecting member 40, and the fixing member 2 penetrates through the through hole 11 of the limiting member 1 and is connected to the connecting member 40.

The limiting component 3 of the present embodiment may further include a connecting member 40, and the fixing member 2 may penetrate through the through hole 11 of the limiting member 1 to connect with the connecting member 40. Thereby, the limiting member 1 and the connecting member 40 are finally connected together by the fixing member 2, and when the fixing member 2 and thus the connecting member 40 are removed, a good fixing effect can be obtained to the fixing member 2 due to the limiting portion 20.

Please refer to fig. 17, fig. 17 is an exploded view of a position limiting assembly according to another embodiment of the present application. In this embodiment, when the limiting portion 20 is disposed on the surface of the substrate 10, on which the through hole 11 is formed, an avoiding groove 41 is formed at one end of the connecting member 40 close to the substrate 10, and the limiting portion 20 is disposed in the avoiding groove 41.

As mentioned above, when the position-limiting portion 20 is directly disposed on the first surface 12, the position-limiting portion 20 occupies a portion of the surface, especially the first surface 12 around the through hole 11, and when the connecting member 40 is connected to the position-limiting member 1 through the fixing member 2, the connecting member 40 abuts against the first surface 12, and the existence of the position-limiting portion 20 may reduce the connection performance between the connecting member 40 and the substrate 10. Therefore, in the present embodiment, an avoiding groove 41 may be formed at one end of the connecting member 40 close to the substrate 10, and when the connecting member 40 is connected to the substrate 10, the limiting portion 20 is disposed in the avoiding groove 41, so that the connecting member 40 is better connected to the substrate 10, and the connection effect between the connecting member 40 and the limiting member 1 is improved.

Please refer to fig. 18, fig. 18 is a schematic structural diagram of a position limiting assembly according to another embodiment of the present application. In this embodiment, the limiting assembly 3 further includes an elastic member 50, the fixing member 2 is sleeved with the elastic member 50, and the elastic member 50 abuts against the fixing member 2 and the substrate 10; when the fixing member 2 penetrates the through hole 11, the elastic member 50 is in a compressed state.

The position limiting member 1 in this embodiment may further include an elastic member 50, and the elastic member 50 itself has elasticity. The elastic element 50 can be sleeved on the fixing element 2, and after the fixing element 2 penetrates through the through hole 11 and is connected with the connecting element 40, the elastic element 50 can abut against the fixing element 2 and the substrate 10, and at this time, the elastic element 50 can be in a compressed state. Since the elastic member 50 applies a force to the fixing member 2 in a direction opposite to the penetrating direction, the stability of the fixing member 2 itself can be improved, and the fixing member 2 can be prevented from shaking. Due to the action of force, the size of the area, which is not provided with the limiting part 20, in the through hole 11 can be further reduced, so that the limiting effect of the limiting part 20 on the fixing part 2 is further improved.
