This design is to maintain the consistency of the bearing and the transmission direction. When the existing bearing seat is in use, due to the long-term rotation of the internal bearing, the entire bearing seat will vibrate, which is very easy to make the screws on both sides of the bearing seat loose, so that the bearing seat will loosen or even fall off on the corresponding device, affecting the subsequent operation and use, so it needs to be improved.

The working principle and use process of the present invention:

First, when the operator needs to install the bearing body 4 between the bearing base 1 and the bearing base cover 2, the bearing body 4 can be placed in the middle of the top of the bearing base 1 first, and then the triangular linkage block 11 can be pushed so that the outer inclined surface squeezes and pushes the two driving inclined surface blocks 12, the driving connecting frame 902 and the locking cylinder 901 to move away from each other, and then the bearing base cover 2 is placed on the top of the mounting hole 3 and the bearing body 4, and then the two rectangular sliders 801 can be pushed to drive the rectangular clamping block 803 to move toward each other and be clamped inside the bearing base cover 2. At this time, the triangular linkage block 11 can be loosened to release the elastic force of the second connecting spring 903, and finally the two driving connecting frames 902 and the locking cylinder 901 can be driven to move toward each other to clamp the inner end of the locking cylinder 901 on the inner wall of the rectangular clamping block 803, so that the rectangular clamping block 803 is clamped on the inner wall of the bearing base cover 2, so that the bearing base cover 2 is fixed to the bearing base 1 and the top of the bearing body 4, thereby realizing the installation of the bearing body 4.

Afterwards, when the bearing body 4 rotates, pressure will be applied to the rubber anti-vibration arc block 501. At this time, the rubber anti-vibration arc block 501 will be deformed and squeeze the shock-absorbing airbag 502, so that the gas in the shock-absorbing airbag 502 is introduced into the interior of the pressure relief pneumatic cylinder 503, thereby slowly pushing the two piston blocks 601 to move opposite to each other, and then part of the gas will be discharged in one direction through the one-way exhaust valve 603. Then, when the piston blocks 601 move opposite to each other, the gas at the outer end of the pressure relief pneumatic cylinder 503 will be compressed and impact the one-way intake valve 604, so that the gas is introduced into the inner cavity of the shock-absorbing airbag 502 for replenishment and recovery. Finally, the loss of pressure will cause the elastic force of the reset spring 602 to drive the piston block 601 to reset towards each other, perfectly releasing the pressure generated by the rotation of the bearing body 4, and realizing pressure relief and shock reduction of the bearing body 4.
