Description

Transfer 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, you usually use pneumatic tools as the power source, and tighten or loosen the nut by docking with the corresponding sleeve . However, generally, the sleeves that are docked with pneumatic tools are made of metal because they need to have a certain degree of rigidity to prevent deformation. During the operation, it is very easy to collide with the sleeve and the rim, resulting in scratches on the rim. This situation is for high-demand car owners or this rim (aluminum alloy rim) is expensive for car owners. In other words, it is extremely unacceptable, and disputes between car repair shops (tire shops) and car owners are often heard. But, as a kind of conventional sleeve disclosed in No. I702116 of my country's patent certificate, it mainly includes a sleeve body and a pipe fitting, and the sleeve body has a head and a body, and the outer diameter of the 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 a slot. 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 fitting has an inserting part, and the inserting part is embedded in the inserting groove of the cylinder body to position the pipe fitting and the sleeve body, even if the pipe fitting and the sleeve body cannot relative rotation. Although, in the structure of this conventional sleeve, the pipe fitting can be used to increase the degree of recognition, that is, the pipe fitting can be printed with words, numbers or patterns for identifying the size. However, since the pipe fitting and the sleeve body are fitted and inserted through the engaging part and the socket groove, the relative rotation between the pipe fitting and the sleeve body cannot be performed (that is, the two will rotate synchronously), so a 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 accidentally touches the rim, it will still produce rolling friction on the rim and cause damage to the rim.

In view of this, in order to improve the problem in the prior art that the conventional sleeve is easy to scratch the rim. For this reason, this creation provides a kind of transfer sleeve structure, comprising: a sleeve body, has a drive portion and an action portion coaxially connected with the drive portion, the free end surface of the drive portion is axially recessed inwards with a Drive hole, the free end surface of the action part is axially recessed to have an action hole, the outer diameter of the drive part is larger than the outer diameter of the action part, so that a step part is formed at the intersection of the drive part and the outer peripheral surface of the action part , there is a first joint part on the outer peripheral surface of the active part; a protective tube, which is made of composite material, is sleeved on the outer peripheral surface of the active part of the sleeve body, and the protective tube and the sleeve itself The system can be rotated relatively, one end of the protective tube abuts against the step; a anti-loosening ring, the inner peripheral surface of the anti-loosening ring has a second joint part, and the anti-loosening ring is placed on the sleeve body On the outer peripheral surface of the active part, the second joint part is combined with the first joint part, and the other end of the protection tube is abutted against the anti-off ring; thereby reducing the wear damage to the rim.
