[0027] The following further elaborates on the present application Figures 1 - 5 in conjunction with the attached drawings.

[0028] The embodiment of the present application discloses a fastening device for a nylon sleeve in a wire winding and unwinding operation.

[0029] A fastening device for a nylon sleeve in a wire winding and unwinding operation is used to install the nylon sleeve 2 on the shaft 1 of a gearbox. The fastening device for a nylon sleeve in a wire winding and unwinding operation includes a nylon sleeve 2, a connecting piece 3, and a fastener 4. The nylon sleeve 2 includes two mounting blocks 21 arranged in a semi-circular ring shape. Mounting holes 22 and fastening holes 23 are formed in the mounting blocks 21. The connecting piece 3 includes a connecting rod 31 passing through the mounting holes 22 and two connecting blocks 32 mounted on the connecting rod 31. The two connecting blocks 32 clamp the two mounting blocks 21. The fastener 4 includes a fastening sleeve 41 installed at the fastening hole 23 and a fastening rod 42 installed inside the fastening sleeve 41.

[0030] When installing the nylon sleeve 2, the two mounting blocks 21 arranged in a semi-circular ring shape clamp the shaft 1 of the gearbox. Then, the connecting rod 31 is passed through the mounting holes 22, and the two connecting blocks 32 clamp the two mounting blocks 21. Then, the fastening rod 42 passes through the fastening hole 23 through the fastening sleeve 41, and the end of the fastening rod 42 abuts against the shaft 1 of the gearbox to perform auxiliary fastening through the fastening rod 42.

[0031] A plane 211 is provided on the mounting block 21. The mounting holes 22 are located at the plane 211. The connecting rod 31 passes through the connecting block 32, and the connecting block 32 and the connecting rod 31 are in threaded connection.

[0032] When connecting two mounting blocks 21, the connecting rod 31 is inserted into the mounting hole 22 for positioning. Then, the connecting blocks 32 are threadedly connected to the connecting rod 31, so that the two connecting blocks 32 clamp the two mounting blocks 21, and the planes 211 on the connecting blocks 32 and the mounting blocks 21 are in contact, further improving the stability of the connecting blocks 32 clamping the mounting blocks 21.

[0033] A plurality of limiting grooves 231 are formed on the inner side wall of the fastening hole 23 and are distributed along the axis 1 direction of the fastening hole 23. The fastening sleeve 41 is provided with limiting strips 411 corresponding to the plurality of limiting grooves 231. The limiting strips 411 are slidably engaged with the limiting grooves 231. A positioning groove 233 is formed at the top of the inner wall of the fastening hole 23, and a positioning ring 415 is mounted on the top of the fastening sleeve 41. The positioning ring 415 is inserted and engaged with the positioning groove 233.

[0034] When the fastening sleeve 41 is installed inside the fastening hole 23, the limiting strips 411 and the limiting ring cooperate with each other to position the fastening sleeve 41, further improving the accuracy of the installation position of the fastening sleeve 41.

[0035] Positioning holes 412 are formed on the inner wall of the fastening sleeve 41. A positioning rod 413 is slidably engaged at the positioning holes 412. Fixing holes 232 corresponding to the plurality of positioning holes 412 are formed on the inner wall of the fastening hole 23. One end of the positioning rod 413 abuts against the fastening rod 42, and the other end of the positioning rod 413 is inserted and engaged with the fixing hole 232. The diameter of the end of the positioning rod 413 away from the fastening rod 42 gradually decreases from the end close to the fastening rod 42 to the end away from the fastening rod 42.

[0036] The fastening rod 42 is threadedly connected to the fastening sleeve 41. When the fastening rod 42 rotates inside the fastening sleeve 41, the fastening rod 42 pushes the pressing cover 414, so that the pressing cover 414 pushes the positioning rod 413 to be inserted into the fixing hole 232, thereby improving the convenience and stability of placing the fastening sleeve 41 inside the fastening hole 23.

[0037] The implementation principle of a tightening device for a nylon sleeve in the embodiments of the present application is as follows: When installing the nylon sleeve 2, the two mounting blocks 21 arranged in a semi-circular shape clamp the shaft 1 of the gearbox. Then, the connecting rod 31 passes through the mounting hole 22 for positioning. Then, through the threaded connection between the connecting block 32 and the connecting rod 31, the two connecting blocks 32 clamp the two mounting blocks 21, and the flat surfaces 211 on the connecting block 32 and the mounting block 21 are in contact, further improving the stability of the connecting block 32 clamping the mounting block 21. Then, the tightening sleeve 41 is installed and inserted into the tightening hole 23, and the tightening sleeve 41 is positioned through the cooperation of the limiting strip 411 and the limiting ring, further improving the accuracy of the installation position of the tightening sleeve 41. Then, the tightening rod 42 is threadedly connected to the tightening sleeve 41, and the end of the tightening rod 42 abuts against the shaft 1 of the gearbox. When the tightening rod 42 rotates inside the tightening sleeve 41, the tightening rod 42 pushes the extrusion cover 414, so that the extrusion cover 414 pushes the positioning rod 413 to insert into the fixing hole 232, so as to improve the convenience and stability of placing the tightening sleeve 41 inside the tightening hole 23.

[0038] The above are all the preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
