Description

Technical Field

[0001] This utility model relates to the field of automotive repair tool technology, specifically a self-priming nut sleeve for automotive wheel hubs with a protective structure. Background Technology

[0002] In modern car repair and maintenance, the installation and removal of wheel hubs is a very common operation. To ensure that the tightening or removal of wheel hub nuts is carried out smoothly, a special tool, namely a nut sleeve, is usually used. It plays a crucial role in actual operation, providing sufficient torque and stability to ensure that the nuts can be tightened or removed correctly, thereby ensuring the safety of the wheel hub and the normal operation of the vehicle.

[0003] When using self-priming nut sleeves to remove or install nuts, the nuts are prone to falling out of the sleeve, requiring repeated manual adjustments and increasing work time. At the same time, the fallen nuts may fall into the chassis gaps, causing trouble for secondary maintenance. Furthermore, the wheel hub working environment contains mud, brake dust, high temperatures, etc. Traditional sleeves lack sealing and wear-resistant protection, and their internal structure is easily contaminated and stuck. Moreover, the teeth are prone to wear after high-frequency impact with the nut.

[0004] Therefore, this utility model provides a self-priming nut sleeve for automobile wheel hubs with a protective structure to solve the above problems. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides a self-priming nut sleeve for automotive wheel hubs with a protective structure, such as... Figure 1-6 As shown, the self-priming nut sleeve for automotive wheel hubs with a protective structure includes a sleeve body 1. The upper end of the sleeve body 1 is provided with a plum blossom internal tooth 2, the lower end of the sleeve body 1 is provided with a wrench docking hole 3, the lower end of the sleeve body 1 is provided with a torque transmission shaft through a high-precision spline, the upper end of the sleeve body 1 is fitted with a rubber protective sleeve 4, and a positioning component is provided inside the upper end of the sleeve body 1.

[0017] The design of the positioning component enables stable adsorption of the nut, further improving the ease of use and work efficiency of the sleeve body 1. At the same time, the rubber protective sleeve 4 not only effectively prevents the entry of external contaminants, but also increases the operator's comfort during use, reduces direct friction between the hand and the sleeve body 1, and protects the operator's safety.

[0018] A protective cap 5 is fitted onto the lower end of the sleeve body 1. An anti-dislodgement retaining ring 6 is provided inside the protective cap 5. The inner wall of the protective cap 5 is wider than the wrench mating hole 3.

[0019] The protective cap 5 provides protection when the wrench connector is connected to the wrench mating hole 3 at the lower end of the socket body 1. The elastic locking within the anti-disengagement retainer 6 prevents the socket body 1 from accidentally falling off the wrench connector during use, ensuring operational safety.

[0020] A guide sleeve 7 is fixedly installed on the upper end of the sleeve body 1, and the lower inner wall of the guide sleeve 7 is flush with the upper opening of the plum blossom internal teeth 2.

[0021] The design of the guide sleeve 7 allows the sleeve body 1 to guide the nut when it is fitted, making it easier for the nut to quickly enter the plum blossom internal teeth 2, which further improves the work efficiency and avoids hard collision between the nut and the sleeve body 1.

[0022] The positioning component includes multiple sets of movable grooves 9, which are opened in the upper end of the sleeve body 1. Each set of movable grooves 9 is equipped with a spring 10, and each set of movable grooves 9 has a top ball 11 movably installed at the opening. The opposite end of each set of top balls 11 is located in the plum blossom internal teeth 2.

[0023] The elastic force of the spring 10 pushes the top ball 11 into close contact with the nut, thereby enabling the nut to be firmly adsorbed and fixed in the plum blossom internal teeth 2 at the upper end of the sleeve body 1. This effectively prevents the nut from accidentally falling off during disassembly or installation, and greatly improves the safety and stability of the operation.

[0024] A permanent magnet is provided on the inner wall of the plum blossom-shaped internal teeth 2 at the upper end of the sleeve body 1, and a magnetic adjustment ring 8 is rotatably installed at the upper end of the sleeve body 1. The design of the magnetic adjustment ring 8 ensures that the operator can flexibly adjust the magnetic strength of the permanent magnet according to the actual work requirements, so that the device can adapt to nuts of various specifications and achieve stable adsorption of them. Through this adjustment mechanism, the applicability of the sleeve body 1 is significantly expanded, and its practical application flexibility and practicality are greatly improved.

[0025] A wear-resistant bushing is provided at the connection between the sleeve body 1 and the torque transmission shaft.

[0026] By setting a wear-resistant bushing between the sleeve body 1 and the torque transmission shaft, the friction between the two is significantly reduced, thereby effectively extending the service life of the sleeve. This not only improves the overall wear resistance but also further ensures the stable operation and reliability of the equipment.

[0027] Working principle: In use, the operator first places the upper end of the sleeve body 1 with the plum blossom internal teeth 2 onto the nut that needs to be disassembled or installed. The springs 10 in the multiple sets of movable grooves 9 push the top ball 11 to abut against the nut, so that the nut is attracted to the plum blossom internal teeth 2 at the upper end of the sleeve body 1. At the same time, the magnetic force adjustment ring 8 can adjust the magnetic force of the permanent magnet according to actual needs, thereby achieving stable attraction of nuts of different specifications, further improving the applicability and practicality of the sleeve body 1. Then, the operator connects the wrench connector to the wrench docking hole 3 and applies torque to the sleeve body 1. The torque is transmitted to the nut through the torque transmission shaft set by the high-precision spline, so as to disassemble or install the nut.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
