Description

Adapter sleeve structure

This creation is related to the accessories of pneumatic tools, more specifically, it refers to an adapter sleeve structure.

Press, when you want to install the rim on the car or remove the rim from the car, generally use pneumatic tools as the power source, and through the docking with the corresponding sleeve to tighten or loosen the nut . However, the sleeves that are generally mated with pneumatic tools need to have a certain degree of rigidity to prevent deformation, so they are all made of metal. During the operation, it is very easy to collide between the sleeve and the rim, resulting in scratches on the rim. This situation is for demanding car owners or the rim (aluminum alloy rim) for expensive car owners. In other words, it is extremely difficult to accept, so that disputes between car repair shops (tire dealers) and car owners are often heard. However, a conventional sleeve disclosed in China's Patent Certificate No. I702116 mainly includes a sleeve body and a tube. The sleeve body has a barrel head and a barrel body, and the outer diameter of the barrel head is larger than the The outer diameter of the barrel is such that the junction between the barrel head and the barrel forms a shoulder surface, and the shoulder surface has an embedded groove. The pipe is made of composite material and is sleeved on the barrel of the sleeve body. On the body, one end of the pipe has an inserting part which is embedded in the inserting groove of the cylinder body to position the pipe and the sleeve body, even if the pipe and the sleeve body cannot Relative rotation. Although, in the structure of the conventional sleeve, the tube can be used to increase the degree of recognition, that is, characters, numbers or patterns for size identification can be printed on the tube. However, because the pipe fitting and the sleeve body are inserted and inserted through the interlocking part and the insertion groove, the relative rotation between the pipe fitting and the sleeve body cannot be performed (that is, the two will rotate synchronously), so one However, when the sleeve body is driven by the pneumatic tool to rotate, the pipe will also be forced to rotate, so that when the pipe is accidentally contacted with the rim, it will still produce rolling friction and damage the rim.

In view of this, in order to improve the problem that the conventional sleeve is prone to scratches on the rim in the prior art. For this reason, this creation provides an adapter sleeve structure, which includes: a sleeve body with a driving part and an action part coaxially connected with the driving part. The free end surface of the driving part is axially recessed inwardly. Driving hole, the free end surface of the acting part is axially recessed with an acting hole, the outer diameter of the driving part is larger than the outer diameter of the acting part, so that a step is formed at the junction of the driving part and the outer peripheral surface of the acting part , The outer peripheral surface of the acting part is provided with a first joining part; a protective tube, which is made of composite material, is sleeved on the outer peripheral surface of the acting part of the sleeve body, and the protective tube and the sleeve are The system is relatively rotatable, one end of the protective tube abuts against the step; an anti-falling ring, the inner peripheral surface of the anti-falling ring has a second connecting portion, and the anti-falling ring is sleeved on the sleeve body On the outer peripheral surface of the acting part, the second joint part is combined with the first joint part, and the other end of the protective tube abuts on the anti-falling ring; thereby reducing wear and damage to the rim.
