The edge of the extrusion plate on one side close to the oil outlet channel is chamfered, and a sealing cover is threadedly connected to the swing arm body, and the sealing cover is located in the oil storage chamber.
[0010] In summary, compared with the prior art, the present invention has the following beneficial effects:
[0011] 1. Due to the setting of the lubrication component, the oiling column can be set so that after the connecting rod is installed in the connecting port, the lubricant can be applied through the oiling ball, thereby reducing the friction between the two, reducing the loss, and then extending the service life of the automobile swing arm.
[0012] 2. Moreover, by setting the squeezing plate, the squeezing plate can be pushed by the squeezing spring to push the lubricating liquid in the oil storage cavity into the oil outlet channel, so that the lubricating liquid can be used for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.
[0020] As shown in Figures 1-5, a long-life automobile swing arm includes a swing arm body 10, characterized in that: three connecting ports 11 are provided on the outer peripheral side of the swing arm body 10, an oil storage chamber 12 and an oil outlet channel 14 are opened in the swing arm body 10, wherein the oil outlet channel 14 extends into two of the connecting ports 11, the oil storage chamber 12 is communicated with the oil outlet channel 14, a lubrication assembly is provided in the oil outlet channel 14, the lubrication assembly includes a baffle 19 fixed in the oil outlet channel 14 and an oiling column 15 sliding in the oil outlet channel 14, the oiling column 15 is mounted on the baffle 19 through a sealing spring On the surface, the middle part of the baffle 19 is hollow, an oiling cavity 18 is opened in the oiling column 15, a connecting hole 17 is opened on the outer peripheral side of the oiling column 15, and an oiling ball 16 is movably connected in the oiling column 15, and lubricating oil is applied through the oiling ball 16. The radius of the oil outlet channel 14 located at the oiling column 15 is smaller than the radius of other parts, the connecting hole 17 is located on the side of the oiling cavity 18 away from the oiling ball 16, and the connecting hole 17 is blocked at the inner wall of the oil outlet channel 14 with a smaller radius. Part of the oiling ball 16 is located in the oiling cavity 18, and part of it is located in the connecting port 11.
[0021] An extrusion plate 13 is fixed in the oil storage chamber 12 by an extrusion spring. The extrusion plate 13 slides in the oil storage chamber 12 . The edge of the extrusion plate 13 on one side close to the oil outlet channel 14 is chamfered. A sealing cover 20 is threadedly connected to the swing arm body 10 , and the sealing cover 20 is located in the oil storage chamber 12 .
[0022] When in use, the sealing cover 20 is removed, and lubricating liquid is injected into the oil storage chamber 12, and the lubricating liquid fills the oil outlet channel 14 and the oil storage chamber 12, and then the sealing cover 20 is installed. When the swing arm is in use, the connecting rod inserted into the connecting port 11 abuts against the oiling ball 16, so that the oiling ball 16 drives the oiling column 15 to squeeze the sealing spring so that the connecting hole 17 is connected with the external oil outlet channel 14, and the lubricating liquid in the oil outlet channel 14 enters the oiling chamber 18, and then when the connecting rod moves, the lubricating liquid in the oiling chamber 18 is The oil is brought out by the oiling ball 16 and smeared between the connecting rod and the connecting port 11, thereby reducing the friction between the two and reducing the loss, thereby extending the service life of the automobile swing arm. When the lubricating liquid in the oil outlet channel 14 is used, the extrusion plate 13 can be pushed by the extrusion spring to push the lubricating liquid in the oil storage chamber 12 into the oil outlet channel 14, so that the lubricating liquid can be used for a long time. When the automobile swing arm is removed, the thrust of the sealing spring moves the oiling column 15 to the connecting hole 17 and is sealed, thereby avoiding leakage of the lubricating liquid.
[0023] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
