Description

Technical Field

[0001] This utility model relates to the field of locking sleeve technology, and in particular to locking sleeves that prevent slippage. Background Technology

[0002] The locking sleeve consists of parts such as a locking bushing, a locking nut, and a locking washer (or locking clip).

[0003] In the prior art, patent document CN211398312U discloses a locking sleeve, including a locking sleeve body. A non-transverse through slot is formed on the outer circumferential surface of the locking sleeve body. The locking sleeve body includes an integrally formed conical segment, a threaded segment, and a positioning ring. The outer surface of the conical segment is a conical surface. A threaded segment extends from one side of the small diameter end of the conical segment. The outer circumferential surface of the threaded segment has an external thread. A positioning ring extends from one side of the large diameter end of the conical segment. The extension of the positioning ring faces the threaded segment. A gap is formed between the inner circumferential surface of the positioning ring extension and the outer conical surface. A nut connected by a thread is provided on the outer circumferential surface of the threaded segment. A through hole is formed between the outer surface of the nut and the inner threaded surface. The through hole communicates with a vertical oil hole formed on the outer circumferential surface of the threaded segment. A plug sealed by a sealing element is provided in the through hole. The lower end of the plug is set in the vertical oil hole. This utility model has a compact structure, is easy to use, and is easy to disassemble and reuse.

[0004] The locking sleeve proposed in the aforementioned patent technology relies solely on the rotation of the nut to lock the locking sleeve body to the shaft surface for fixation during actual installation. It lacks corresponding anti-detachment components, which makes the nut prone to loosening after long-term use. This leads to an increase in the gap between the locking sleeve body and the shaft assembly, making it easy for the sleeve to fall off. In view of this, this application proposes an anti-detachment locking sleeve. Utility Model Content

The inner wall of the threaded holes is threaded with hexagon socket head cap screws 403. The outer surface of the plug ring 401 has an annular locking groove 404 corresponding to the plurality of hexagon socket head cap screws 403.

[0035] Reference Figure 2 and Figure 3 In a preferred embodiment, an annular locking pad 405 is fixedly provided on the inner wall of the annular locking groove 404, and the material of the annular locking pad 405 is elastic rubber.

[0036] By setting an annular locking washer 405, the threaded end of the internal hex bolt 403 can squeeze and deform the annular locking washer 405, thereby achieving effective locking and fixing between the fixing ring 600 and the locking nut 200.

[0037] In this invention, by setting a locking component 400, the locking sleeve can quickly and effectively lock the locking nut 200 during actual installation, thus preventing the locking nut 200 from loosening during the use of the locking sleeve and enabling the locking sleeve to achieve the purpose of preventing it from falling off.

[0038] The positioning component 500 is used to fix the retaining ring 600 to the outer surface of the locking bushing 100.

[0039] Reference Figure 3 In a preferred embodiment, the positioning component 500 includes a cylindrical cavity 501 formed on the inner annular surface of the fixing ring 600, and a positioning post 502 slidably disposed on the inner wall of the cylindrical cavity 501. The outer surface of the fastening bushing 100 is provided with a positioning groove 503 corresponding to the positioning post 502.

[0040] By setting the positioning pin 502 and the positioning groove 503, the fixing ring 600 and the locking bushing 100 can be effectively fixed.

[0041] Reference Figure 3 In a preferred embodiment, a return spring 504 is fixedly provided at the end of the positioning post 502, and the other end of the return spring 504 is fixedly connected to the inner wall of the cylindrical cavity 501.

[0042] By setting a reset spring 504, the positioning pin 502 can be automatically inserted into the positioning groove 503 under the action of the reset spring 504.

[0043] Reference Figure 3 In a preferred embodiment, a pull rod 505 extending to the outer surface of the fixing ring 600 is fixed at the end of the positioning post 502, and a pull ring 506 is fixed at the end of the pull rod 505 away from the positioning post 502.

[0044] Reference Figure 3 In a preferred embodiment, the inner wall of the cylindrical cavity 501 is provided with a through hole extending to the outer surface of the fixing ring 600, and the pull rod 505 is slidably connected to the inner wall of the through hole, and the return spring 504 is sleeved on the outer surface of the pull rod 505.

[0045] By setting up a pull rod 505 and a pull ring 506, during the disassembly of the locking sleeve, the pull ring 506 can be pulled outward to drive the pull rod 505 to pull the positioning post 502, so that the positioning post 502 is disengaged from the positioning groove 503, thereby achieving the purpose of facilitating the quick disassembly of the fixing ring 600 and the locking bushing 100.

[0046] In this invention, by setting a positioning component 500, after the locking washer 300 is placed on the outer surface of the locking bushing 100, the fixing ring 600 and the locking bushing 100 can be effectively fixed, thereby effectively ensuring the stability of the connection between the fixing ring 600 and the locking bushing 100.

[0047] Working principle: During actual installation, the locking bushing 100 is placed on the shaft, and the locking washer 300 is placed on the outer surface of the locking bushing 100. Then, the locking nut 200 is rotated, causing it to move downwards and effectively press against the outer surface of the shaft, thus securing the locking bushing 100 to the shaft. As the locking nut 200 rotates, it moves downwards. After the locking bushing 100 is locked, the insertion ring 401 at the bottom of the locking nut 200 can be inserted into the annular insertion groove 402 on the fixing ring 600. At this time, the internal hexagonal bolt 403 is rotated using an external hexagonal wrench, pressing it against the annular locking washer 405 on the inner wall of the annular locking groove 404, thereby securing the locking nut 200. The purpose of the locking mechanism is to quickly and effectively tighten the locking nut 200, preventing it from loosening during use and thus ensuring the locking sleeve is resistant to falling off. After the locking washer 300 is placed on the outer surface of the locking bushing 100, the locking washer 300 and the retaining ring 600 can be rotated. During the rotation of the retaining ring 600, the positioning pin 502 remains in contact with the outer surface of the locking bushing 100 under the action of the return spring 504. When the positioning pin 502 aligns with the positioning groove 503, it inserts into the positioning groove 503 under the action of the return spring 504, effectively fixing the retaining ring 600 and the locking bushing 100 together, thus ensuring the stability of the connection between the retaining ring 600 and the locking bushing 100.

[0048] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
