In an initial state, the diameter of the fixing cavity 46 is smaller than the maximum diameter of the conical guide insertion-connection part 51, when the conical guide insertion-connection part 51 is inserted into the insertion-connection hole 40 (i.e. when the hand component 5 is installed), the first elastic limiting claw 44 and the second elastic limiting claw 45 are gradually expanded outwards, when the diameter of the fixing cavity 46 is larger than or equal to the maximum diameter of the conical guide insertion-connection part 51, the guide insertion-connection part 51 continues to move until the guide insertion-connection part 51 moves out of the fixing cavity 46 and the insertion shaft 50 is located in the fixing cavity 46, at this time, the upper and lower positions of the insertion shaft 50 are limited by the elastic action of the first elastic limiting claw 44 and the second elastic limiting claw 45, and when the guide insertion-connection part 51 continues to be inserted and the limiting boss 55 blocks the insertion-connection limiting part 52 to continue to move, at this time, the maximum stroke of the plug shaft 50 is obtained, and the left and right positions of the plug shaft 50 are limited by the guide plug part 51 and the plug limiting part 52, so that the second connection assembly is mounted. Adopt the 5 mounting means of hand component of plug-in type, for current with the 5 mounting means of equipment hand component after trunk body dismantlement earlier, the equipment step that has significantly reduced has reduced the equipment degree of difficulty, effectively improves the packaging efficiency.

In addition, if want to dismantle hand component 5 from truck body 4 out, need take truck body 4 apart earlier, then dismantle second coupling assembling out to the completion is dismantled hand component 5, like this under hand component 5 and truck body 4 assembled state, can't directly extract, in order to guarantee the installation steadiness.

In an embodiment, the joint structure includes a first joint body 1, a second joint body 2, and a first connection assembly for connecting the first joint body 1 and the second joint body 2, where the first connection assembly includes an installation hole 10 opened on the first joint body 1, an installation component 20 installed on the second joint body 2 and used for being snap-fitted to the installation hole 10, and a first limiting member 3 used for limiting a snap-fit position of the installation component 20 when the installation component 20 is snap-fitted to the installation hole 10.

Specifically, the first joint body 1 includes a first shell 14 and a second shell 15 which are installed in an involutory manner, one part of the installation hole 10 is opened on the first shell 14, and the other part of the installation hole 10 is opened on the second shell 15.

During assembly (at this time, the first housing 14 and the second housing 15 are in a state of being assembled in a closed manner), the mounting member 20 is installed on the mounting hole site 10 in a clamped manner, and the clamping position of the mounting member 20 is limited by the first limiting member 3, in this state, the mounting member 20 cannot be directly disassembled from the mounting hole site 10, so that the stability of clamping and installation of the mounting member 20 and the mounting hole site 10 is ensured, and the first connecting assembly can be used in a high-strength environment (such as shaking vigorously, drawing the first joint body 1 and/or the second joint body 2, and the like), so that the first connecting assembly adopts a clamping and matching manner to install the second joint body 2 on the first joint body 1, compared with a manner that the trunk body 4 needs to be disassembled first and then assembled with a joint in the prior art, steps required for assembly are reduced, the assembly effect is effectively improved, and the labor intensity of an assembler is also reduced, can be applied to the joint connection parts of toys such as figures, animals, robots and the like; in addition, the mounting member 20 and the mounting hole site 10 can be directly detached from the mounting hole site 10 in the clamping fit state, so that the user and the assembling personnel can detach the mounting member 20 more conveniently.

When the first housing 14 and the second housing 15 are disassembled, the mounting member 20 is separated from the mounting hole site 10, so that the mounting member 20 and the mounting hole site 10 are disassembled, and the disassembling step is simple.

In addition, after the mounting part 20 is in clamping fit with the mounting hole site 10, the first joint body 1 and the second joint body 2 are of a rotatable structure or a non-rotatable structure, and the selection of the rotatable structure or the non-rotatable structure can be preset in the machining process according to different production requirements.

In an embodiment, the mounting hole site 10 includes a clamping hole 11 for clamping and matching with the mounting member 20 and a mounting hole 12 communicated with the clamping hole 11; when the mounting part 20 enters the clamping hole 11 from the mounting hole 12, the first limiting part 3 is arranged in the mounting hole 12 to limit the clamping position of the mounting part 20.

Specifically, the diameter of the clamping hole 11 is smaller than that of the mounting hole 12, and the clamping hole 11 is located below the mounting hole 12; installation part 20 gets into from mounting hole 12 during the equipment, moves afterwards in joint hole 11 rather than carrying out the joint, and first locating part 3 is spacing to the joint position of installation part 20 in mounting hole 12 this moment to avoid installed part 20 to follow shifting out of joint hole 11, thereby effectively guarantee the stability of being connected of installed part 20 and joint hole 11's joint structure.

In addition, the clamping hole 11 may also be located above the mounting hole 12, and the specific mounting steps in this manner are the same as those in the case where the clamping hole 11 is located below the mounting hole 12, which is not described herein again.

In an embodiment, the mounting member 20 includes a clamping shaft 21 and a clamping limiting portion 22, one side of the clamping shaft 21, which is far away from the second joint body 2, is fixedly connected with the clamping limiting portion 22, and one side of the clamping shaft 21, which is close to the second joint body 2, is rotatably connected with the second joint body 2; when the mounting part 20 is in clamping fit with the mounting hole site 10, the clamping shaft 21 penetrates through the clamping hole 11.

Specifically, the shape of the clamping limiting portion 22 is cylindrical, the axis of the clamping limiting portion 22 is parallel to the axis of the clamping shaft 21, and the diameter of the clamping shaft 21 is smaller than the diameter of the clamping limiting portion 22, so that a height difference is formed between the outer circumferential surface of the clamping limiting portion 22 and the outer circumferential surface of the clamping shaft 21 to form a clamping limiting cavity 24 for clamping and matching with the clamping hole 11, meanwhile, the diameter of the clamping hole 11 is larger than the diameter of the clamping shaft 21 and smaller than the diameter of the clamping limiting portion 22, and the diameter of the clamping limiting portion 22 is smaller than the diameter of the mounting hole 12, so that the clamping limiting portion 22 can be conveniently mounted in the mounting hole 12, and the clamping shaft 21 can be conveniently and rotatably mounted in the clamping hole 11.

More specifically, the second joint body 2 is provided with a first avoidance sliding groove 25 for allowing the fastening shaft 21 to rotate. This makes it possible to provide a more compact connection between the second joint body 2 and the joint shaft 21, and to simulate the joint motion of a human more realistically.

It is further specifically explained that the second joint body 2 is provided with a support portion 26 for supporting the clamping limiting portion 22. Because the outer circumferential surface of the clamping limiting part 22 and the outer circumferential surface of the clamping shaft 21 form a height difference, when the mounting part 20 is clamped and matched with the mounting hole site 10, the clamping limiting part 22 is clamped and matched through the supporting part 26, so that the clamping limiting part 22 is prevented from inclining and inclining, and meanwhile, the downward movement stroke of the clamping shaft 21 is limited.

During the equipment, insert the spacing portion 22 of joint in the mounting hole 12 until joint axle 21 is located mounting hole 12, later with joint axle 21 remove to joint hole 11 in carry out the joint cooperation, first locating part 3 is spacing to the joint position of installed part 20 in mounting hole 12 this moment, it is spacing to position about joint axle 21 to have formed like this, and position about joint axle 21 is spacing through spacing portion 22 of joint and second joint body 2, thereby effectively guarantee joint axle 21's installation steadiness.

In an embodiment, a first guiding portion 23 is disposed on a side of the clamping limiting portion 22 away from the second joint body 2 to facilitate the clamping limiting portion to enter the mounting hole 12.

Specifically, the first guide portion 23 is conical, and an axis of the first guide portion 23 is parallel to an axis of the clamping shaft 21; first guide part 23 is used for solving because the second body blocks the sight and can't make the accurate installation of spacing portion 22 of joint to mounting hole 12's problem in the assembling process, and in the assembling process, when first guide part 23 was located near mounting hole 12, the circular conical surface of the first guide part 23 of accessible direction gets into in mounting hole 12 to guarantee that spacing portion 22 of joint can be fast and accurate installation to mounting hole 12 in.

In an embodiment, the first limiting member 3 includes an elastic arm 30, and a fixing portion 31 and a limiting stop portion 32 respectively disposed at two ends of the elastic arm 30, the limiting stop portion 32 is disposed in the mounting hole 12, and the first joint body 1 is provided with a fixing column 33 for mounting the fixing portion 31.

Under initial state, spacing fender portion 32 is located mounting hole 12, when installed part 20 inserts in mounting hole 12, spacing fender portion 32 can receive the extrusion thrust of installed part 20 and make it move to the inside of first joint body 1, spacing fender portion 32 uses the junction of fixed part 31 and fixed column 33 to remove as the fulcrum this moment, and drive elastic arm 30 and remove and make it produce elastic deformation and form the energy storage, and when installed part 20 moved to joint hole 11 in from mounting hole 12, installed part 20 carries out the joint cooperation with joint hole 11 this moment, elastic arm 30 utilizes simultaneously energy storage drive spacing fender portion 32 resets, it is spacing to be used for carrying on the joint position of installed part 20 in mounting hole 12 until spacing fender portion 32 is located, design benefit, stable in structure is reliable.

In one embodiment, one implementation: the fixing portion 31 is fixedly connected with the fixing column 33. Such structural design can make the elastic arm 30 obtain sufficient deformation and form the energy storage to effectively guarantee limit baffle's the accuracy nature that resets, and then guaranteed the joint stability of installed part 20 with installation hole site 10 joint cooperation structure.

In another embodiment: the fixing portion 31 is rotatably connected with the fixing post 33, and the first joint body 1 is provided with a stroke limiting portion 13 for limiting the rotatable stroke of the fixing portion 31. Specifically, the stroke limiting portion 13 is a limiting transverse plate installed on the first joint body 1, and such a structural design makes the first limiting member 3 have a certain rotatable space and a smaller rotatable range, so as to avoid the phenomenon that the service life of the elastic arm 30 is short and/or the abrasion between the fixing portion 31 and the fixing column 33 is serious due to the hard connection between the fixing portion 31 and the fixing column 33.

In an embodiment, a side of the limit stop 32 close to the second joint body 2 is provided with a second guiding portion 34 for facilitating the installation component 20 to enter the clamping hole 11 from the installation hole 12.

Specifically, the second guide portion 34 is an arc-shaped guide surface, and the distance from the left side to the right side of the limit stop portion 32, that is, the distance from the side of the limit stop portion 32 away from the second joint body 2 to the arc-shaped guide surface gradually decreases from top to bottom.

Under the initial condition, spacing fender portion 32 is located mounting hole 12, and when installed part 20 was installed to mounting hole 12, installed part 20 can exert extrusion thrust to spacing fender portion 32, and spacing fender portion 32 was gradually removed to first joint body 1 inside this moment, and installed part 20 can be followed the arc spigot surface and slided down gradually simultaneously, and in until installed part 20 got into joint hole 11, effectively improved installed part 20's installation convenience through second guide portion 34 like this, the practicality is strong.
