Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

As shown in fig. 1 to 8, a loose-joint type tightening device includes a body of a binding hoop, which is distinctive in that: the one end of constraint hoop body is provided with links up head end 1, and the other end of constraint hoop body is provided with links up tail end 2, considers the location locking needs during actual staple bolt, has the bolt subassembly 3 of drawing at linking up head end 1, linking swing joint between tail end 2, has constituted a bolt subassembly structure. Meanwhile, in order to meet the requirement of realizing effective hoop combination under the premise of small-diameter floating range, the final hoop combination degree can be adjusted by matching with the pulling bolt component 3, the binding hoop body comprises a plurality of clamping units 4 with radian, and a hoop section structure 5 is connected between the clamping units 4. Like this, possess the regulation degree of freedom of preferred in the assembly, laminating that can be better around the circular stand commonly used reduces the appearance at laminating dead angle.

In view of a preferred embodiment of the present invention, in order to meet the subsequent requirement of auxiliary installation of various power equipment fixing bodies 11, an auxiliary positioning device may be additionally installed on the binding hoop body. Specifically, the invention can also be provided with an arm assembly 6 on the hoop structure 5, wherein the arm assembly 6 is provided with an arm connecting piece 7, and the arm connecting piece 7 is connected with a U-shaped fastener 9 through a positioning bolt 8. Therefore, a positioning space is formed between the arm connecting piece 7 and the U-shaped fastener 9, and the auxiliary bolt 10 penetrates through the positioning space of the arm connecting piece 7 and the U-shaped fastener 9. Therefore, the power equipment fixing body 11 which needs to be correspondingly positioned can be placed in the positioning space, and the loading capacity of the invention is improved. Furthermore, a plurality of auxiliary positioning devices can be arranged according to the requirement of actual layout.

Further, the support arm assembly 6 adopted by the invention is of a T-shaped structure, the tail end of the T-shaped structure is connected with the hoop section structure 5 through a locking screw 26, and the head end of the T-shaped structure is connected with the support arm connecting piece 7 through the locking screw 26. In this way, the load-bearing capacity of the arm assembly 6 can be improved. In practical implementation, two T-shaped structures can be adopted to be clamped, connected and positioned up and down. Meanwhile, in order to match the appearance of the traditional power equipment fixing body 11, the inner side surfaces of the support arm connecting piece 7 and the U-shaped fastener 9 in the positioning space are provided with arc positioning surfaces.

In view of practical implementation, in order to realize uniform stress, the tightening unit 4 includes a hoop section connecting sheet 12 distributed in a mirror image manner, a plurality of connecting bolts 13 penetrate through the hoop section connecting sheet 12, and the connecting bolts 13 on two sides are connected with corresponding hoop section structures 5. Meanwhile, in order to ensure that the hoop section connecting pieces 12 on the upper side and the lower side can be uniformly stressed during use, and combined stress is not only acted on the connecting bolt 13, a supporting pipe 14 is sleeved outside the connecting bolt 13. Thus, the distance between the two hoop section connecting sheets 12 in each hoop unit 4 can be kept constant and the stress can be uniformly transmitted by the existence of the supporting tube 14.

Still further, in order to carry the tightening unit 4 connected to itself, the hoop structure 5 used in the present invention comprises a block body, which is provided with a plurality of connecting holes 24 through it, which can be used to connect with the connecting bolts 13. Meanwhile, the inner side surface of the block body is provided with a contact groove 25. Thus, for some of the more common tower posts 17, which tend to be cylindrical in shape, effective contact limiting can be achieved by the presence of the contact grooves 25. The contact groove 25 may have a V-shape or an arc shape in order to fit different joint surfaces. Of course, other shapes such as wave shapes can be adopted for realizing the combination requirement of various special-shaped pole towers 17. This allows the hoop structure 5 to better conform to the surface of the tower post 17 to which it is mounted. In view of actual manufacturing, after the manufacturing is finished, the cross section of the block body is of a continuous closed structure, the outline of the block body is free of a cavity and a hollow structure similar to an extrusion part and a die casting part, and the bearing effect is better. Furthermore, in order to achieve better contact, the cross section of the block body may be rectangular, or may be in other shapes such as an elliptical D-shape, and may be distributed in a more conforming manner according to the actual interface shape of the pole tower 17.

Considering the stability of the combined force application of the final hoop, the adopted connecting head end 1 is provided with a pulling bolt limiting groove 19 and a V-shaped groove 20. Correspondingly, the connecting tail end 2 is provided with a waist hole 21, and the bolt component 3 is arranged in the waist hole 21. Meanwhile, the adopted pulling bolt component 3 comprises a pulling bolt body 22, the tail end of the pulling bolt body 22 is provided with a limiting sheet 23, the head end of the pulling bolt body 22 is provided with a cross rod 18, and the outer side of the cross rod 18 is provided with a nut 15. Thus, when the head end 1 and the tail end 2 are combined, the cross bar 18 is inserted into the V-shaped groove 20. In addition, during the locking process, a user can freely adjust the position of the control cross rod 18 of the nut 15 to limit the final locking gap, so that the actual diameter of the hooping body after hooping is controlled, and the hooping tower 17 can be better hooped. Meanwhile, in consideration of the subsequent penetrating requirement of the connecting bolt 13, a plurality of engagement holes 16 can be respectively formed at the engagement head end 1 and the engagement tail end 2.

The working principle of the invention is as follows:

the user surrounds the body of the tie down strap around the conduit. Subsequently, the upper pulling bolt component 3 is installed between the connection head end 1 and the connection tail end 2, and the binding hoop body is hooped on the pipeline through the screwing of the pulling bolt component 3. If the power equipment fixing body 11 needs to be additionally arranged, the support arm connecting piece 7 and the U-shaped fastener 9 which the auxiliary positioning device belongs to are opened, one side of the power equipment fixing body 11 is abutted against the support arm connecting piece 7, and then the U-shaped fastener 9 is connected into the support arm connecting piece 7 through the locking screw 26, so that the use is convenient. For some perforated wire passing management, an auxiliary bolt 10 can be additionally arranged to improve the tightness of the combination.

As shown in fig. 4-6, in practical use, for some fixed bodies with smaller diameter, such as thinner tower columns 17, one pulling bolt assembly 3 is adopted. For a fixing body with a moderate diameter, two binding hoop bodies can be selected and connected end to end oppositely, namely, two pulling bolt assemblies 3 are adopted to realize combination. Moreover, for some thicker fixing bodies, three binding hoop bodies can be adopted for use, and locking is realized by means of three pulling bolt assemblies 3. Of course, the number of the loose joint type tightening devices can be added according to the requirement of field layout, and the details are not repeated herein. Further, a corresponding number of auxiliary positioning devices may be disposed for different power equipment fixing bodies 11 that are actually required, and the description thereof is omitted.
