[0026] A natural rubber sleeve 12 is nested and installed on the top of the bushing body 1, and sliders 13 are fixedly installed on the left and right ends of the natural rubber sleeve 12, and a slot 22 is provided on the outer side of the slider 13, a slide groove 14 is provided on the inner side of the upper end of the bushing body 1, a return spring 15 is fixedly installed on the inner middle end of the bushing body 1, and a block 16 is fixedly installed on the inner side of the return spring 15, and a traction rope 17 is fixedly installed on the outer side of the block 16, a pull rod 19 is fixedly installed on the lower end of the traction rope 17, and a groove 18 is provided on the outer side of the lower end of the bushing body 1.

[0027] The left and right ends of the positioning rod 7 are fixedly installed on the lower end of the bushing body 1, and a buffer spring 8 is nested on the surface of the positioning rod 7, and the inner side of the buffer spring 8 is fixedly installed on the outer side of the buffer block 6, and the outer side of the buffer spring 8 is fixedly installed on the bottom of the bushing body 1, the buffer block 6 and the buffer spring 8 are connected in a sliding manner, and the buffer block 6 forms an elastic structure with the bushing body 1 through the buffer spring 8, and a damping rod 9 is fixedly installed between the bushing body 1 and the guide column 2, and a limiting slide rod 10 is fixedly installed on the upper end of the base 3, and the limiting slide rod 10 is nested in the inside of the limiting groove 11, and the limiting slide rod 10 and the limiting groove 11 are connected in a sliding manner;

[0028] according to Figure 1 and Figure 2The chassis shock-absorbing bushing with built-in natural rubber is installed in the working position by installing bolts 4. When the device is working, the bushing body 1 will move up and down along the guide column 2. When the bushing body 1 slides up and down along the guide column 2, the buffer rod 5 is squeezed. At this time, since the upper and lower ends of the buffer rod 5 are rotatably installed, the buffer rod 5 pushes the buffer block 6 to squeeze the buffer spring 8 outward along the positioning rod 7. The buffer spring 8 is relieved by its own elastic force. At this time, the damping rod 9 between the bushing body 1 and the guide column 2 offsets the repeated rebound force of the buffer spring 8, so that the device can have a good shock-absorbing effect. At the same time, when the bushing body 1 slides up and down, the limiting slide bar 10 slides up and down along the limiting groove 11 to form a limit, so that the bushing body 1 will not deviate, and the stability can be guaranteed while improving the shock-absorbing effect;

[0029] The shape of the block 16 is inclined, and the block 16 forms an elastic structure with the bushing body 1 through the reset spring 15, and the block 16 forms a clamping structure with the slider 13 through the clamping groove 22, and the slider 13 is connected to the slide groove 14 in a sliding connection, the pull rod 19 forms a traction structure with the block 16 through the traction rope 17, and the upper end of the pull rod 19 is connected to the groove 18 in a sliding connection, and the outer side of the bushing body 1 is fixedly installed with an anti-aging layer 20, and the outer side of the anti-aging layer 20 is fixedly installed with a wear-resistant layer 21;

[0030] according to Figure 1 , Figure 3 , Figure 4 and Figure 5When the natural rubber sleeve 12 is to be installed inside the sleeve body 1, the sliders 13 at the left and right ends of the natural rubber sleeve 12 are slid along the slide groove 14 inside the sleeve body 1, so that the natural rubber sleeve 12 is nested inside the sleeve body 1. When the slider 13 slides along the slide groove 14, the slider 13 squeezes the block 16. Due to its own inclination, when the slider 13 contacts the block 16, the block 16 squeezes the return spring 15 inwardly. The return spring 15 is squeezed and retracted inwardly until the position of the block 16 corresponds to the slot 22. The return spring 15 clamps the block 16 in the slot 22 through its own elastic force, so that the return spring 15 can be pressed inwardly. The natural rubber sleeve 12 can be engaged. At this time, the block 16 is pushed by the reset spring 15 and the pull rod 19 is pulled by the traction rope 17. When the natural rubber sleeve 12 needs to be removed, the pull rods 19 at the left and right ends are pulled. The pull rods 19 slide downward along the groove 18 and pull the traction rope 17. The traction rope 17 pulls the block 16 to squeeze the reset spring 15 outward, so that the block 16 is disengaged from the engagement with the card slot 22, so that the natural rubber sleeve 12 can be taken out, achieving the effect of easy installation and removal. At the same time, an anti-aging layer 20 is attached to the surface of the bushing body 1 to improve the service life of the device, and a wear-resistant layer 21 is provided on the outside of the anti-aging layer 20 to make the device more wear-resistant.
