Description

Sleeve structure

This creation is related to the accessories of pneumatic tools, more specifically refers to a 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, the nut is tightened or loosened . Of course, the sleeves that are generally docked with pneumatic tools are made of metal because they need to have a certain rigidity to prevent deformation, and the sleeves are tightened or loosened at the moment of the nut, or before and after the action During the operation, it is very easy for the sleeve to collide with the rim, resulting in scratches on the rim. This situation is for high-demand owners or this rim (aluminum alloy rim) is a very expensive car owner. It is extremely difficult to accept, making disputes between car repair shops (tire lines) and car owners often heard. Therefore, a car repair shop (tire row) will cover other slightly soft items (such as fabric) on the outer circumference of the sleeve to prevent scratching the rim, but it is not only inconvenient in use, but also difficult to extend The rim is for the sleeve to extend into the hole, which is difficult to apply. Therefore, some manufacturers have developed a method of placing a plastic sleeve on the sleeve, but a plastic sleeve that is too thin does not have a protective effect, and a plastic sleeve that is too thick will not extend into the hole on the rim, but instead cut The outer diameter of the original sleeve makes the overall rigidity insufficient, and the plastic sleeve is in tight surface contact with the sleeve during the sleeve connection process, which makes it difficult to assemble.

In view of this, in order to improve the prior art, the conventional sleeve is prone to scratches on the rim, and placing foreign objects on the sleeve may be inconvenient to use, poorly protected, and difficult to extend into the rim. Problems such as insufficient overall rigidity and difficulty in assembly. Therefore, the present invention provides a sleeve structure including a sleeve body, an O-ring and a carbon fiber tube; the sleeve body has a driving part and an action part coaxially connected with the driving part, the driving part The outer diameter of the driving part is greater than the outer diameter of the acting part, a step is formed at the junction of the outer peripheral surface of the driving part and the acting part, the free end surface of the driving part is axially recessed with a driving hole inward, The inner axial depression has an action hole, and the action portion is surrounded by a ring groove on the outer peripheral surface; the O-ring tether is sleeved in the ring groove of the sleeve body; the carbon fiber tube is sleeved in the action portion of the sleeve body On the outer peripheral surface, one end is in contact with the stepped portion, and the inner peripheral surface is in contact with the O-ring; in order to avoid scratches on the rim, improve convenience, enhance protection, apply to existing rims, Maintain the overall rigidity and ease of assembly.

In order to enable your reviewing committee to have a better understanding and recognition of the characteristics and characteristics of this creation, the following examples are listed below and illustrated with the drawings: Please refer to the first to third figures, which is a sleeve structure 100 provided by a preferred embodiment of the present invention, which mainly includes a sleeve body 10, an O-ring 20 and a carbon fiber tube 30, in which: Please refer to the first to third figures. The sleeve body 10 is a cylindrical cylinder made in one piece. The sleeve body 10 has a driving portion 11 and an action portion 12 coaxially connected with the drive portion 11 integrally, and the outer diameter of the drive portion 11 is greater than the outer diameter of the action portion 12, so that the drive portion 11 and the A step portion 13 is formed at the junction of the outer peripheral surface of the action portion 12. A free hole surface of the drive portion 11 extends axially from the axial position to a drive hole 111. In this embodiment, the drive hole 111 is a square hole. A positioning hole 112 is formed on the outer peripheral surface of the driving portion 11 radially through the center of the circle. The free end surface of the acting portion 12 extends axially inwardly from the axial position to an inward hole 121. In this embodiment, the acting hole 121 is a hexagonal hole, and an annular groove 122 is formed around the outer surface of the acting portion 12. Please refer to the first to third figures. The O-ring 20 is a circular ring body made of rubber or other elastic materials. The O-ring 20 is encased in the ring groove 122 of the sleeve body 10 and only partially protrudes from the ring groove 122. Please refer to the first to third figures. The carbon fiber tube 30 is an axially hollow tube made of carbon fiber. The carbon fiber tube 30 is sleeved on the outer peripheral surface of the action portion 12 of the sleeve body 10, and abuts on the step portion 13 from one end thereof, and abuts on the O-ring 20 from its inner peripheral surface, so that the The outer circumferential surface of the carbon fiber tube 30 is flush with the outer circumferential surface of the driving portion 11, and the inner circumferential surface of the carbon fiber tube 30 is spaced from the outer circumferential surface of the action portion 12. The thickness of the carbon fiber tube 30 is between 0.3 mm and 0.8 mm. Therefore, the above is an introduction to the components and combinations of the sleeve structure 100 provided in a preferred embodiment of the present invention, and then the use characteristics are introduced as follows: First, because the carbon fiber tube 30 can produce an extremely thin tube wall, and still maintain a certain hardness (the hardness is still lower than the hardness of the metal) in the state where the tube wall is extremely thin. Therefore, after the carbon fiber tube 30 of the extremely thin tube wall is sleeved on the sleeve body 10, its overall outer diameter does not increase too much, so that it can be applied to the existing rim, and the overall outer diameter does not Too much increase does not need to reduce the outer diameter of the original sleeve body 10, but can maintain the overall rigidity, and the hardness of the carbon fiber tube 30 can also increase the anti-friction loss effect to increase the service life, so that this creation can not only To avoid damage to the rim, it is more convenient, easy to protect, suitable for existing rims and maintain overall rigidity. Secondly, when the carbon fiber tube 30 is sleeved on the sleeve body 10, it does not come into face-to-face contact with the sleeve body 10, but only contacts the O-ring 20. Therefore, not only can the assembly efficiency be achieved, but also the consumables such as the carbon fiber tube 30 and the O-ring 20 can be easily replaced. In addition, although the number of the ring groove 122 and the O-ring 20 in this creation are one each in the above embodiment, in order to allow the sleeve body 10 and the carbon fiber tube 30 to be more tightly sleeved, the amount can be appropriately increased according to actual needs The number of the ring groove 122 and the O-ring 20. In addition, although in the above embodiment, the driving hole is a square hole, and the acting hole is a hexagonal hole. However, in fact, the driving hole and the acting hole can be any one of a four-corner hole, a hexagonal hole, an octagonal hole, a twelve-corner hole, or a hexagonal star hole. The above disclosures are only the preferred embodiments provided by this creation, and are not intended to limit the scope of the implementation of this creation. Any changes in the art of the relevant arts based on this creation should belong to this creation. Coverage.
