[0004] The above-mentioned pneumatic transmission mechanism of the tire changer still has certain shortcomings: since the pneumatic transmission mechanism does not have the function of lubrication, once the internal components of the pneumatic transmission mechanism are used for a long time, the friction between the components will increase, thereby reducing the sealing of the pneumatic transmission mechanism. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a pneumatic transmission mechanism of a tire changer. By setting a lubrication component, when the pneumatic transmission rod has been working for a period of time, the hydraulic lifting rod inside the lubrication component is started to drive the stabilizing rod and the piston to move downward. Because the surface of the piston fits with the inner wall of the storage cylinder, the lubricating oil inside the storage cylinder can be transported to the inside of the connecting pipe while the piston moves. Finally, the lubricating oil is transported to the inside of the pneumatic transmission rod by the connecting pipe to lubricate its internal parts, thereby improving the sealing of the device to solve the problems existing in the prior art.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a pneumatic transmission mechanism of a tire changer, comprising a tire changer body, a pneumatic transmission rod fixedly connected to one side of the top of the tire changer body, a tire changer head fixedly connected to the bottom end of the pneumatic transmission rod, a limiting hole provided at the top end of the back side of the pneumatic transmission rod, a fastening ring bonded to the inside of the limiting hole, and a lubrication assembly connected to the top end of the back side of the pneumatic transmission rod through the fastening ring.

[0007] Wherein, the material of the fastening connection ring is a rubber component, and the length of the fastening connection ring is smaller than the depth of the limiting hole.

[0008] Among them, the lubrication assembly includes a connecting plate, a limiting through hole and a storage cylinder. The bottom end of the side wall of the connecting plate is penetrated by a limiting through hole. The cross-sectional area of ​​the limiting through hole is the same as the cross-sectional area of ​​the fastening connecting ring. The interior of the storage cylinder is filled with lubricating oil.

[0009] Wherein, the bottom end of the side wall of the connecting plate is connected with a quick plug pin through the limiting through hole, and one end of the quick plug pin is adapted to the inside of the fastening connecting ring through the limiting through hole.

[0010] The top end of the other side wall of the connecting plate is fixedly connected to a support plate, and a hydraulic lifting rod is detachably mounted on one side of the lower surface of the support plate.

[0011] The bottom end of the hydraulic lifting rod is fixedly connected to a stabilizing rod, and the bottom end of the stabilizing rod is fixedly connected to a piston, and the surface of the piston is adapted to the interior of the storage cylinder.

[0012] Wherein, the bottom end of the storage cylinder is connected to a connecting pipe, and the bottom end of the connecting pipe is connected to the top end of the pneumatic transmission rod.

[0013] The beneficial effects of the above technical solution of the utility model are as follows:

[0014] 1. In the above solution, the pneumatic transmission mechanism is provided with a lubrication assembly. When the pneumatic transmission rod has been operating for a period of time, the hydraulic lifting rod inside the lubrication assembly is activated, causing it to move the stabilizing rod and the piston downward. Because the surface of the piston contacts the inner wall of the storage cylinder, the lubricating oil inside the storage cylinder is transported to the interior of the connecting pipe as the piston moves. Finally, the connecting pipe transports the lubricating oil to the interior of the pneumatic transmission rod, lubricating its internal parts, thereby improving the sealing performance of the device.

[0015] 2. In the above scheme, the pneumatic transmission mechanism is provided with a limit hole, a fastening connection ring, a limit through hole and a quick plug-in pin. When the lubrication assembly needs to be disassembled, the quick plug-in pin is pulled out from the inside of the fastening connection ring and the limit through hole respectively, and the lubrication assembly can be separated from the pneumatic transmission rod. Because the quick plug-in pin is clamped in the fastening connection ring and the limit through hole, it can be directly pulled out. Therefore, compared with other connection methods, this connection method saves more time during disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The material of the fastening connecting ring 5 is a rubber component. The length of the fastening connecting ring 5 is less than the depth of the limiting hole 4. The lubricating assembly 6 includes a connecting plate 61, a limiting through hole 62 and a storage cylinder 68. The bottom end of the side wall of the connecting plate 61 is penetrated by a limiting through hole 62. The cross-sectional area of ​​the limiting through hole 62 is the same as that of the fastening connecting ring 5. The interior of the storage cylinder 68 is filled with lubricating oil. The bottom end of the side wall of the connecting plate 61 is connected to a quick plug-in pin 63 through the limiting through hole 62. One end of the quick plug-in pin 63 is passed through The limiting through hole 62 is adapted to the interior of the fastening connecting ring 5, and the top of the other side wall of the connecting plate 61 is fixedly connected to a support plate 64. A hydraulic lifting rod 65 is detachably installed on one side of the lower surface of the support plate 64. The bottom end of the hydraulic lifting rod 65 is fixedly connected to a stabilizing rod 66, and the bottom end of the stabilizing rod 66 is fixedly connected to a piston 67. The surface of the piston 67 is adapted to the interior of the storage cylinder 68. The bottom end of the storage cylinder 68 is connected to a connecting pipe 69, and the bottom end of the connecting pipe 69 is connected to the top of the pneumatic transmission rod 2.

[0025] Benefits: By setting the material of the fastening ring 5 to a rubber component, it is helpful to ensure the stability of the lubrication component 6 during installation.

[0026] The working process of this utility model is as follows:

[0027] When the pneumatic transmission mechanism is in use, in order to improve the sealing of the device, a lubrication component 6 is provided. After the pneumatic transmission rod 2 has been working for a period of time, the hydraulic lifting rod 65 inside the lubrication component 6 is started to drive the stabilizing rod 66 and the piston 67 to move downward. Because the surface of the piston 67 fits against the inner wall of the storage cylinder 68, the lubricating oil inside the storage cylinder 68 can be transported to the inside of the connecting pipe 69 while the piston 67 moves. Finally, the connecting pipe 69 transports the lubricating oil to the inside of the pneumatic transmission rod 2 to lubricate its internal parts, thereby improving the sealing of the device.

When the lubrication component 6 needs to be disassembled, the quick-plug pin 63 is respectively pulled out from the inside of the fastening ring 5 and the limiting through-hole 62 to separate the lubrication component 6 from the pneumatic transmission rod 2. Because the quick-plug pin 63 is clamped in the fastening ring 5 and the limiting through-hole 62 and can be directly pulled out, compared with other connection methods, this connection method saves more time during disassembly.
