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, a pneumatic tool is generally used as the power source, and the nut is tightened or loosened by connecting with the corresponding sleeve. . However, the sleeves that are generally connected to the pneumatic tools are made of metal because they need to have a certain rigidity to prevent deformation. During the operation, it is very easy for the sleeve to collide with the rim, resulting in scratches on the rim. This situation is very important for the owner of the car with high requirements or the owner of the rim (aluminum alloy rim) who is expensive. It is extremely difficult to accept, so that disputes between auto repair shops (tire shops) and car owners are often heard. However, as disclosed in Chinese Patent Certificate No. I702116, a conventional sleeve mainly includes a sleeve body and a pipe fitting, the sleeve body has a cylinder head and a cylinder body, and the outer diameter of the cylinder head is larger than the cylinder head. The outer diameter of the cylinder body is such that a shoulder surface is formed at the junction between the cylinder head and the cylinder body. The shoulder surface has an insert groove. The pipe is made of composite material and is sleeved on the sleeve of the sleeve body. On the body, one end of the pipe piece has an inserting part, and the inserting part is embedded in the inserting groove of the cylinder body, so as to locate the pipe piece and the sleeve body, even if the pipe part and the sleeve body cannot be relative rotation. Although, in the structure of the conventional sleeve, the tube can be used to increase the recognition, that is, characters, numbers or patterns for identifying the size can be printed on the tube. However, because the pipe fitting and the sleeve body are connected by the fitting and inserting of the inserting portion and the inserting groove, the pipe fitting and the sleeve body cannot rotate relative to each other (that is, the two rotate synchronously). Therefore, a However, when the sleeve body is driven by the pneumatic tool to rotate, the pipe fitting will also be forced to rotate, so that when the pipe fitting accidentally contacts the rim, rolling friction will still occur on the rim, resulting in damage to the rim.

In view of this, in order to improve the problem of the prior art, the conventional sleeve is prone to scratch the rim. Therefore, the present invention provides an adapter sleeve structure, comprising: a sleeve body, a driving part and an action part coaxially connected with the driving part, the free end surface of the driving part is axially recessed inward with a Drive hole, the free end surface of the action part is axially recessed inward with an action hole, the outer diameter of the driving part is larger than the outer diameter of the action part, so that a step is formed at the intersection of the driving part and the outer peripheral surface of the action part , the outer peripheral surface of the action portion has a first joint portion; a protection tube, made of composite material, is sleeved on the outer peripheral surface of the action portion of the sleeve body, and the protection tube and the sleeve are originally The system can be rotated relatively, and one end of the protection tube is in contact with the step; an anti-releasing ring has a second joint part on the inner peripheral surface of the anti-releasing ring, and the anti-releasing ring is sleeved on the sleeve body On the outer peripheral surface of the action part, the second joint part is combined with the first joint part, and the other end of the protection tube is abutted on the anti-dropping ring, so as to reduce the wear and damage to the rim.
