[0059] Below, refer to Figures 1 to 3 (F) The moving harness fixing device of the embodiment of the present invention is described. The moving harness fixing device of the embodiment of the present invention can not only avoid stress concentration in the moving harness under torsion or tension, which makes installation of the moving harness and opening and closing of the moving side component relative to the fixed side component difficult, but also avoid interference with the environment during movement, which affects the reliability and service life of the moving harness.

[0060] In these figures, in order to facilitate the explanation of the detailed structure of the moving wire harness fixing device, the central axis direction of the inner sleeve 1 and the supporting sleeve 2 sleeved on the outside thereof is set as the axial direction CL, one side of the axial direction CL is set as the CL1 side, and the other side of the axial direction CL is set as the CL2 side.

[0061] (Overall Structure of Sports Harness Fixing Device 100)

[0062] In this embodiment, if Figure 1 、 2As shown, the sports harness fixing device 100 includes: an inner sleeve 1, which is generally cylindrical in shape, including a first inner sleeve 11 and a second inner sleeve 12, wherein the first inner sleeve 11 includes a semi-cylindrical first inner sleeve body 111, a first inner sleeve flange 112 formed on the outer peripheral surface of both ends of the axial direction CL of the first inner sleeve body 111, and first ear pieces 113 extending from the first inner sleeve flange 112 to the CL1 side and the CL2 side, respectively, and a first ear piece 113 is formed on the first ear piece 113. The first fastening hole 1131 is a rectangular hole. The second inner sleeve 12 includes a semi-cylindrical second inner sleeve body 121, a second inner sleeve flange 122 formed on the outer peripheral surface of both ends of the axial direction CL of the second inner sleeve body 121, and second ears 123 extending from the second inner sleeve flange 122 to the CL1 side and the CL2 side respectively. The second ears 123 are respectively formed with second fastening holes 1231, which are rectangular holes; the supporting sleeve 2, The support sleeve 2 is generally cylindrical and includes a semi-cylindrical upper support sleeve 21 and a semi-cylindrical lower support sleeve 22, wherein the upper support sleeve 21 includes an upper support sleeve body 211 and upper support sleeve flanges 212 formed on both sides of the axial direction CL of the outer peripheral surface of the upper support sleeve body 211 on the CL1 side and the CL2 side, and the lower support sleeve 22 includes a lower support sleeve body 221 and lower support flanges 212 formed on both sides of the axial direction CL of the outer peripheral surface of the lower support sleeve body 221 on the CL1 side and the CL2 side. The support sleeve flange 222 has a clamp mounting portion 23 that is recessed radially inward and extends along the axial direction CL formed between the upper support sleeve flange 212 and the lower support sleeve flange 222. The clamp mounting portion 23 is used to install the clamp 3; and the clamp 3, the clamp 3 is generally cylindrical, including a cylindrical clamp main body 31, the clamp main body 31 is formed with a notch, and a thin sheet-like clamp fixing portion 32 is extended radially outward from the notch, and a fixing hole 321 is hollowed out in the clamp fixing portion 32.

[0063] In the sports harness fixing device 100 constructed as described above, the inner diameter of the support sleeve 2 is larger than the outer diameter of the inner sleeve 1. In this way, when the support sleeve 2 is sleeved on the outer circumference of the inner sleeve 1, the support sleeve 2 can support the inner sleeve 1 so that it can rotate and move.

[0064] Moreover, in this embodiment, in order to reliably combine the support sleeve 2, as shown in FIG. Figure 1 As shown, a cylindrical boss 2221 and a groove 2222 are respectively formed on the CL2 side of the axial CL of the lower support sleeve flange 222 of the lower support sleeve 22. Although not shown in the figure, a cylindrical groove 2222 and a boss 2221 are also correspondingly formed on the CL2 side of the axial CL of the upper support sleeve flange 212 of the upper support sleeve 21.

[0065] Moreover, although Figure 1 Only the boss 2221 and groove 2222 on the CL2 side of the lower support sleeve flange 222 are shown, but the boss and groove on the CL1 side, as well as the boss and groove on the upper support sleeve flange 212, have the same structures as the boss 2221 and groove 2222 described above. Thus, by providing bosses and grooves on both sides of the support sleeve 2 in the axial direction CL (i.e., the CL1 side and the CL2 side) and fitting the bosses into the grooves, the support sleeve 2 can be securely assembled.

[0066] Moreover, if Figure 2 As shown, when the first inner sleeve 11 and the second inner sleeve 12 are docked, the first fastening hole 1131 of the first ear piece 113 overlaps with the second fastening hole 1231 of the second ear piece 123. By passing the cassette 13 through the first fastening hole 1131 and the second fastening hole 1231 and fastening them, the sports harness 200 therein can be secured so that it cannot move.

[0067] Furthermore, the outer circumferential surfaces of the upper support sleeve 21 and the lower support sleeve 22 of the support sleeve 2 include a portion between the upper support sleeve flange 212 and a portion between the lower support sleeve flange 222 as a clamp mounting portion 23 for mounting the clamp 3. To reliably secure the clamp 3 to the clamp mounting portion 23, in this embodiment, the axial length of the clamp mounting portion 23 is set to be equal to the axial length of the clamp body portion 31 of the clamp 3 that is sleeved on the support sleeve.

[0068] In addition, if Figure 2 As shown, the two clamp fixing portions 32 extending radially outward from the clamp body 31 are each thin-sheet-shaped and vertically stacked, and each clamp fixing portion 32 is hollowed out to form a fixing hole 321. By inserting a fixing screw through the fixing hole 321 of the clamp fixing portion 32 of the clamp 3 and tightening the fixing screw into the mounting hole of the machine body, the clamp 3 can be securely fastened to the machine body.

[0069] (Moving Harness Fixing Process by Moving Harness Fixing Device 100)

[0070] Below, refer to Figure 3 (A) to (F) illustrate the process of fixing the moving harness by the moving harness fixing device 100.

[0071] like Figure 3 As shown in (A), one end of the motion harness 200 is fixed with a clamp 4, and as Figure 3 As shown in (B), the other end of the motion harness 200 is pre-twisted 180° counterclockwise, and then, as shown in Figure 3 As shown in (C), the clamp 5 is fixed to the other end of the motion harness 200.

[0072] Then, if Figure 3 As shown in (D), the inner sleeve 1 is placed on the portion between the clamp 4 and the clamp 5 of the motion harness 200, and the inner sleeve 1 is fastened by the cassette 13 so that it cannot move relative to the motion harness 200.

[0073] Then, if Figure 3 As shown in (E), the bosses of the upper support sleeve 21 and the lower support sleeve 22 are engaged with the grooves to sleeve the cylindrical support sleeve 2 on the inner sleeve 1.

[0074] Next, the clamp body 31 of the clamp 3 is sleeved on the supporting sleeve 2 , and a fixing screw is inserted through the fixing hole 321 of the clamp fixing portion 32 of the clamp 3 and then tightened on the machine body.

[0075] In this way, since the moving harness 200 in the inner sleeve 1 can rotate or move relative to the supporting sleeve 2, even if the moving harness 200 is twisted or stretched, the twisting or stretching will be absorbed by the moving harness fixing device 100. In this way, stress concentration on the moving harness 200 can be avoided.

[0076] Moreover, since the moving part of the moving harness 200 located between the clamp 4 and the clamp 5 is fixed by the clamp 3, it can avoid the moving part between the clamp 4 and the clamp 5 from interfering with the environment, thereby affecting the reliability and service life of the moving harness 200.

[0077] Above, in order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention are clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0078] Furthermore, in the above process, the moving harness is pre-twisted in reverse, thereby reducing the torsional stress generated by the harness during movement.

[0079] The preferred embodiments of the present invention have been described. However, in addition to the technical solutions described in the above embodiments, the elements of the above embodiments may be combined to obtain the technical solutions of the present invention without violating the purpose of the present invention.

[0080] In the above embodiment, the boss and the groove are formed on both sides of the support sleeve in the axial direction CL, but the present invention is not limited thereto. The boss and the groove may be formed only on one side of the support sleeve in the axial direction CL.

[0081] In the above embodiment, in the process of fixing the motion harness by the motion harness fixing device, an example of pre-twisting the motion harness by 180° is cited, but the present invention is not limited thereto and other degrees of pre-twisting are also possible.
