[0022] Embodiment 1: This embodiment is intended to solve the problem that when the damping tool is in use, the frequent operation of the machine may cause the sealing ring to be subjected to additional friction and pressure, thereby causing it to slide in the installation groove. When the sealing ring slides, friction and wear will increase, which may cause damage to the sealing ring itself, thereby affecting the reliability and life of the machine. Please refer to Figure 1-5 A shock-absorbing tool comprises a shock-absorbing tool body 110 and a sealing ring body 120. The shock-absorbing tool body 110 is configured as a U-shaped block. A connecting column 111 is installed on the side of the shock-absorbing tool body 110. A plurality of connecting columns 111 are provided. The plurality of connecting columns 111 are respectively connected to both sides of the shock-absorbing tool body 110. The sealing ring body 120 is detachably installed on the outer side of the connecting column 111.

[0023] The sealing ring body 120 is configured as an annular rubber ring, and a snap-fit ​​assembly 130 is arranged inside the sealing ring body 120. A snap-fit ​​groove 112 is opened on the side of the connecting column 111. The snap-fit ​​assembly 130 is slidably engaged with the snap-fit ​​groove 112. The snap-fit ​​assembly 130 includes a mounting column 131 and a support column 132. The mounting column 131 is connected to the inner wall of the sealing ring body 120, and the support column 132 is connected to the side of the mounting column 131.

[0024] A plurality of support columns 132 are provided, and the plurality of support columns 132 are respectively connected to both sides of the mounting column 131. An arc head 133 is connected to the end of the support column 132, and the arc head 133 is set as a rubber head. A snap-fit ​​tip 134 is connected to the end of the support column 132, and the snap-fit ​​tip 134 is set as a triangular tip. A support groove 135 and a sharp groove 140 are also provided inside the mounting column 131. The sharp groove 140, the support groove 135 and the snap-fit ​​groove 112 are connected and arranged. The support column 132 is slidably engaged with the support groove 135, and the snap-fit ​​tip 134 is slidably engaged with the sharp groove 140.

[0025] In this embodiment, through the arrangement of the snap-fit ​​assembly 130 and the snap-fit ​​groove 112, when installing the sealing ring body 120, the sealing ring is sleeved on the outside of the connecting column 111, and the snap-fit ​​assembly 130 is pressed into the inside of the snap-fit ​​groove 112. The mounting column 131, the support column 132 and the snap-fit ​​tip 134 are respectively connected to the inside of the snap-fit ​​groove 112, the support groove 135 and the tip groove 140. When the sealing ring body 120 is subjected to pressure, the support column 132 is snapped with the support groove 135 to avoid the problem of misalignment or falling off of the sealing ring body 120 and the connecting column 111. When disassembling, twist the sealing ring body 120 , so that the locking assembly 130 and the locking groove 112 are unlocked. Through the locking of the support column 132 and the support groove 135, it can be ensured that when the sealing ring body 120 is subjected to pressure, the position between the sealing ring and the connecting column 111 is stable, and the sealing ring is prevented from being misplaced or falling off, thereby ensuring the integrity and effectiveness of the seal, and solving the problem that when the shock-absorbing tool is in use, the frequent operation of the machine may cause the sealing ring to be subjected to additional friction and pressure, causing it to slide in the installation groove. When the sealing ring slides, friction and wear will increase, which may cause damage to the sealing ring itself, thereby affecting the reliability and life of the machine.

For details, please refer to Figure 1-5 A rotating shaft 141 is inserted into the sealing ring body 120, and a solid rubber ball 142 is connected to the outside of the rotating shaft 141. The solid rubber ball 142 slides with the connecting column 111. The sliding fit of the solid rubber ball 142 fills the gap between the connecting column 111 and the sealing ring, further improving the sealing effect and reducing the possibility of leakage.

[0027] In this embodiment: through the provision of a solid rubber ball 142, the solid rubber ball 142 cooperates with the connecting column 111. When subjected to pressure, the solid rubber ball 142 squeezes the outer side of the connecting column 111. The squeezing of the solid rubber ball 142 can evenly distribute the pressure, reduce the local pressure on the sealing ring, and help to extend the service life of the sealing ring.
