Description

Technical Field

[0001] The utility model relates to the technical field of oil seals, in particular to an improved automobile shock absorber oil seal. Background Art

[0002] Oil seal is a common name for general seals, which simply means the seal of lubricating oil. It is a mechanical component used to seal grease (oil is the most common liquid substance in the transmission system, and also refers to general liquid substances). It isolates the parts that need lubrication from the output parts in the transmission parts to prevent the lubricating oil from leaking.

[0003] The existing automobile shock absorber oil seal device does not have the function of quickly disassembling the oil seal body during use, which makes it very troublesome and time-consuming to replace the oil seal each time, thereby affecting the efficiency of oil seal replacement. Secondly, the existing automobile shock absorber oil seal device also has the problem that the shock absorber cannot be stably connected during use, which makes it necessary to install the shock absorber and the oil seal base step by step each time. Improvements are now made. Utility Model Content

[0010] As a preferred technical solution of the utility model: a handle is fixedly installed on the top of the sliding rod 1.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The improved automobile shock absorber oil seal, through the cooperation of the slide bar 1 and the arc groove, utilizes the sliding connection between the bayonet pin 1 and the clamping hole 1, and then the oil seal body can be firmly clamped in place.

When it needs to be disassembled, it only needs to squeeze the bayonet pin 1 inwardly, so that the bayonet pin 1 squeezes the spring 1 to deform and shrink. At this time, the bayonet pin 1 is separated from the inner wall of the clamping hole 1 on the outer edge of the outer frame, and then the oil seal body can be taken out, which is convenient for disassembly and replacement of the oil seal body.

[0013] 2. The improved automobile shock absorber oil seal, through the coordinated use of the slide groove and the second bayonet pin, utilizes the sliding connection between the second bayonet pin and the inner wall of the second bayonet hole, thereby causing the second bayonet pin and the second bayonet hole to be mutually engaged, and through the adaptation of the diameters between the second slide rod and the slide groove, the second slide rod can smoothly slide into the inner wall of the slide groove, and then utilizes the engagement between the second bayonet pin and the second bayonet hole to connect the chassis and the shock absorber body.

After the slide bar 7 and the slide bar are slid down along the slide rail, the slide bar 7 is rotated to clamp the slide bar on the inner wall of the arc groove, thereby achieving a secondary fixing effect on the oil seal body 4, making the oil seal body 4 more stable. When it is necessary to disassemble, the bayonet pin 9 can be squeezed inward to make the bayonet pin 9 squeeze the spring 8 to deform and shrink. At this time, the bayonet pin 9 is separated from the inner wall of the card hole 5 on the outer edge of the outer frame 2, and the oil seal body 4 can be taken out, which is convenient for disassembly and replacement of the oil seal body 4. Secondly, through the sliding connection between the bayonet pin 15 and the inner wall of the card hole 13, the bayonet pin 15 and the card hole 13 are engaged with each other. Through the matching of the diameters between the slide rod 10 and the slide groove 12, the slide rod 10 can smoothly slide into the inner wall of the slide groove 12.
