Description

Technical Field

[0001] This utility model relates to the field of inflator piston technology, and in particular to an inflator piston structure with wear prevention. Background Technology

[0002] An air compressor is a type of reciprocating air compressor. Its compression element is a piston that reciprocates inside a cylinder, pumping gas along the piston. Derivative products include air compressors, assembly line equipment, plastic injection molding machines, and fans.

[0003] An air compressor mainly consists of a power system, a transmission system, an air compression system, a cooling system, and an oil lubrication system. The air compression system includes a suction pipe, high and low pressure air cylinders, pistons, and air valves, which are responsible for compressing air into high-pressure air.

[0004] The piston on the inflator's connecting rod is prone to wear as it contacts and reciprocates within the cylinder. As the piston wears and thins, it can cause the connecting rod to come into direct contact with the cylinder. Since the connecting rod is made of metal, contact with the cylinder can scratch the cylinder's inner wall.

[0005] Therefore, it is necessary to provide a piston structure for an inflator that prevents wear in order to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides a piston structure for an air compressor that prevents wear, solving the problem that the piston on the existing air compressor rod wears thin after a period of use, causing the rod head to rub against the cylinder wall and scratch it.

[0007] To solve the above-mentioned technical problems, the present invention provides an air compressor piston structure with wear prevention, comprising: a pull rod;

[0008] The insertion tube is fixedly connected to the top of the pull rod. The top of the pull rod is equipped with a pull rod head. A mating plate is installed on the top of the pull rod head through a through-hole. A wear-resistant gasket is installed on the top of the mating plate through a through-hole. A piston is installed on the top of the wear-resistant gasket through a through-hole. A pressure ring is provided on the top of the piston. Insertion holes are opened on both sides of the top of the pull rod head, the wear-resistant gasket, the mating plate, and the piston. Mounting rods are fixedly connected to the bottom of the pressure ring on both sides. Nuts are threadedly connected to the outer surface of the mounting rod near the bottom.

[0009] A connecting groove is formed at the top of the insertion tube. An external threaded post is threaded into the inside of the connecting groove, and a rotating disk is fixedly connected to the top of the external threaded post.

[0010] The pull rod head is located on the outer surface of the insertion tube. The wear-resistant gasket, mating plate, and piston are all fitted on the outer surface of the insertion tube. The bottom end of the mounting rod is inserted from the insertion port at the top of the piston and then passes out from the bottom of the pull rod head.

[0011] Preferably, a mating bolt is fixedly connected to the bottom of the pull rod, and the outer surface of the mating bolt is provided with a mounting hole;

[0012] The connection between the bolt and the piston is structurally linked, and the mounting holes facilitate bolt insertion and increase connection stability.

[0013] Preferably, the bottom end of the pull rod is provided with a sealing ring, and the wear-resistant gasket is made of non-metallic wear-resistant material.

[0014] Preferably, a mating groove is provided on the top of the piston near the outer surface, and threaded holes are provided on the bottom of the inner wall of the mating groove near the four corners.

[0019] Compared with related technologies, the wear-resistant inflator piston structure provided by this utility model has the following beneficial effects:

[0020] This invention provides a piston structure for an inflator that prevents wear. To avoid the piston wearing down and causing the tie rod head to scratch the inner wall of the cylinder, a wear-resistant gasket is installed between the tie rod head and the piston via a mating plate. Then, a pressure ring is installed on the top of the piston, and an installation rod is inserted through a socket and exits from the bottom of the tie rod head. The piston is then installed by connecting the nut and the installation rod, increasing the stability of the connection between the piston, the wear-resistant gasket, and the tie rod head. The tie rod and tie rod head are then connected via a rotating disk with an externally threaded post and a connecting tube with a connecting groove, further enhancing the stability of the connection. This design incorporates a wear-resistant gasket between the piston and the tie rod head. The wear-resistant gasket is made of non-metallic wear-resistant material and is larger than the outer diameter of the tie rod head, thus preventing the tie rod head from scratching the inner wall of the cylinder after the piston wears down.

The nut 3 is located at the bottom of the pull rod head 4, and the rotating disk 9 is located at the top of the pressure ring 8.

[0033] The bottom of the pull rod 1 is fixedly connected to a mating bolt 12, and the outer surface of the mating bolt 12 is provided with a mounting hole 11;

[0036] The sealing ring 10 is fitted onto the outer surface of the mating plug 12.

[0037] The working principle of the wear-resistant inflator piston structure provided by this utility model is as follows:

[0038] A wear-resistant gasket 6 is installed between the pull rod head 4 and the piston 7 via the mating plate 5.

The second embodiment of this application proposes another inflator piston structure with wear prevention. The second embodiment is merely a preferred embodiment of the first embodiment, and its implementation will not affect the independent implementation of the first embodiment.

[0043] Specifically, the difference in the wear-resistant inflator piston structure provided in the second embodiment of this application is that a mating groove 21 is provided on the top of the piston 7 near the outer surface, and threaded holes 20 are provided on the bottom of the inner wall of the mating groove 21 near the four corners.
