A flange 2 is constructed on the outer edge of the top end of the bushing tube 1, and a plurality of first fixing holes 201 are formed in the flange 2. A lumen 101 is arranged inside the bushing tube 1, and a rubber sleeve 3 is fixedly clamped on the outer surface of the bushing tube 1. Wherein, one end of the rubber sleeve 3 protrudes and is higher than the outer surface of the bushing tube 1, so that the rubber sleeve 3 can fill and seal between the bushing tube 1 and the inner wall of the installation hole.
[0032] Meanwhile, a receiving notch 4 is formed on the outer surface of the bushing tube 1 corresponding to the protruding end of the rubber sleeve 3, and the receiving notch 4 can receive the rubber sleeve 3 with excessive extrusion deformation.
[0033] Cooperating Figure 3 as shown, a storage cavity 5 for storing lubricating oil liquid is formed at the top inside the lumen 101. A fixing bolt 6 is fixed on the inner wall of the storage cavity 5. One end of the fixing bolt 6 is located at the inner wall of the lumen 101 and is provided with a sponge block 7. The other end of the fixing bolt 6 is located inside the storage cavity 5 and is provided with an oil supply pipe 8 communicating with the sponge block 7. The oil supply pipe 8 is a capillary tube, and one end of the oil supply pipe 8 passes through the inside of the fixing bolt 6 and is connected with the sponge block 7, and the other end extends to the bottom inside the storage cavity 5.
[0034] During specific implementation, the sponge block 7 is fixed on the bolt head of the fixing bolt 6 and extends into the lumen 101, and a groove for placing the bolt head of the fixing bolt 6 is formed on the inner wall of the lumen 101.
[0035] In addition, in other embodiments, as Figure 4 shown in another embodiment, the difference from the above embodiment is that: a bottom ring 9 is matched with the bottom of the bushing tube 1, and a plurality of second fixing holes 901 are formed in the bottom ring 9, and the installation position of the bushing tube 1 can be stabilized by the cooperation of the bottom ring 9 and the flange 2.
[0036] The working principle provided by the present utility model is as follows. For this shock-absorbing bushing, during use, the rubber sleeve 3 can be utilized to fill the gap between the liner tube 1 and the hole, and the excess part extruded from the rubber sleeve 3 can be accommodated in the accommodation notch 4. Therefore, it is beneficial to ensure the sealing effect between the device and the hole.
[0037] Meanwhile, during the use process, by storing lubricating liquid in the storage cavity 5, the liquid can be supplied to the sponge block 7 via the oil supply pipe 8, enabling the sponge block 7 to lubricate the shaft passing through the lumen 101, effectively reducing the wear between the bushing and the shaft, and prolonging the service life of the device and the shaft.
[0038] In summary, this device not only has a good sealing effect with the hole, but also has small wear with the shaft, a long service life, and a good overall use effect.
