DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] Embodiment one, please refer to Figure 1 - Figure 6 In the utility model embodiment, a wire harness elastic locking structure, including with the external shell 100 rotation installation's balance wheel 200, the top of balance wheel 200 is fixed with locking block one 210 and locking block two 220, locking block one 210 and locking block two 220 between the pre-set gap, the outside of balance wheel 200 is fixed with clamping block 230, both ends of balance wheel 200 and shell 100 are all provided with tension spring 300, the top of balance wheel 200 is provided with the positioning wheel 400 of rotation connection with shell 100, positioning wheel 400 is arranged at the top of balance wheel 200, the bottom surface of positioning wheel 400 is fixed with positioning block 410, locking block one 210 and locking block two 220 two with positioning block 410 activity clamping.

[0028] Specifically, the pull spring 300 is connected to both ends of the balance wheel 200 to replace the traditional wide elastic sheet to drive the balance wheel 200 to reset, so that the volume of the elastic device of the locking structure is reduced. The locking block one 210 and the locking block two 220 are fixed on the top of the balance wheel 200 to adapt to the locking of the positioning block 410 at the bottom of the positioning wheel 400, so that the balance wheel 200 is locked and fixed to rotate the wire winding wheel 120. The positioning wheel 400 does not need to reserve different groove positions in terms of the depth of the gear, so the thickness of the positioning wheel 400 is reduced in terms of the gear, so that the smaller shell 100 can install the locking structure, and the convenience and practicality of the telescopic data line are improved.

[0029] As shown in Figure 5 , in the embodiment, the wire winding wheel 120 rotates in the shell 100. The top of the wire winding wheel 120 is provided with a plurality of clamping grooves 121 which are movably clamped with the clamping blocks 230. When the data line is pulled, the clamping grooves 121 on the wire winding wheel 120 move with the clamping blocks 230 to rotate the balance wheel 200. The rotation of the balance wheel 200 stretches the pull spring 300. When the data line is released later, the contraction of the pull spring 300 drives the rotating balance wheel 200 to rotate to the initial position.

[0030] As shown in Figure 2 , in the embodiment, one side of the clamping block 230 is provided with an arc surface one 231, which can smoothly pass through the clamping block 230. The top surface of the balance wheel 200 is fixed with a limiting block 260. The limiting block 260 prevents the balance wheel 200 from swinging in a large range in the shell 100.

[0031] As shown in Figure 2 , in the embodiment, the top of the balance wheel 200 is provided with a mounting hole one 270, and the inside top of the shell 100 is fixed with a connecting shaft which is rotatably connected with the mounting hole one 270, so that the balance wheel 200 can be rotatably installed in the shell 100.

[0032] As shown in Figure 2 , in the embodiment, the bottom surface of the balance wheel 200 is provided with an oil hole 250. The oil hole 250 can add lubricating oil to the rotating part of the locking structure after the shell 100 is disassembled.

[0033] As shown in Figure 1 , in the embodiment, the top of the positioning wheel 400 is fixed with a rotating column 420, and the outside of the shell 100 is provided with a mounting hole two which is rotatably installed with the rotating column 420.

[0034] As shown in Figure 3As shown in the embodiment, the outer side of the positioning block 410 is symmetrically provided with two arc-shaped surfaces 411 and locking grooves 412, and when the locking block one 210 and the locking block two 220 on the balance wheel 200 are clamped between the adjacent arc-shaped surfaces 411 and the locking grooves 412, the balance wheel 200 is limited and locked by the positioning wheel 400.

[0035] In the second embodiment, on the basis of the first embodiment, the rotating balance wheel 200 can automatically return to the initial position to lock the wire winding wheel 120.

[0036] As shown in the embodiment, both ends of the tension spring 300 are fixed with hooks, the inner top surface of the shell 100 is fixed with two connecting columns one 110 which are respectively rotationally sleeved with the corresponding position hooks, and both ends of the balance wheel 200 are fixed with connecting columns two 240 which are respectively rotationally sleeved with the corresponding position hooks. Figure 1 Figure 5 Figure 6 As shown in the embodiment, both ends of the tension spring 300 are fixed with hooks, the inner top surface of the shell 100 is fixed with two connecting columns one 110 which are respectively rotationally sleeved with the corresponding position hooks, and both ends of the balance wheel 200 are fixed with connecting columns two 240 which are respectively rotationally sleeved with the corresponding position hooks.

[0037] Specifically, when the balance wheel 200 rotates, the tension spring 300 is stretched, so that the tension spring 300 generates a tension spring force, and the tension spring force drives the rotating balance wheel 200 to rotate to the initial position, so that the rotating balance wheel 200 can rotate back to the initial position.

[0038] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of equivalent elements of the claims are intended to be embraced in the present application. Any reference signs in the claims should not be considered as limiting the claims involved.

[0039] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.​​
