[0026] As Figures 1-6 shown, the present utility model provides an anti-offset shock absorber compression valve seat, comprising: a valve seat body 1, and an installation mechanism 2 is arranged on the valve seat body 1;

[0027] The installation mechanism 2 includes four card slots 201 and two arc-shaped slots 203. A perforated cross-shaped block 202 is arranged inside the four card slots 201. Springs 204 are arranged inside the two arc-shaped slots 203. Two arc-shaped blocks 205 are slidably connected inside each arc-shaped slot 203. A perforated arc-shaped plate 206 is fixed to the top of each arc-shaped block 205. Two arc-shaped rods 207 are fixed inside each arc-shaped slot 203. An arc-shaped clamping rod 208 is fixed to the opposite side of each group of arc-shaped blocks 205. The four card slots 201 are equidistantly distributed on the top of the valve seat body 1, and the inside of the four card slots 201 is communicated with the inside of the valve seat body 1. The perforated cross-shaped block 202 is movably sleeved inside the valve seat body 1. The two arc-shaped slots 203 are symmetrically arranged on the top of the valve seat body 1. The four card slots 201 are divided into two groups. Each arc-shaped slot 203 is respectively located between each group of card slots 201. The four arc-shaped blocks 205 are divided into two groups. The opposite sides of each group of arc-shaped blocks 205 are respectively in contact with both sides of the inner wall of each arc-shaped slot 203, and the opposite sides of each group of arc-shaped blocks 205 are respectively installed with both ends of each spring 204. The four perforated arc-shaped plates 206 are divided into two groups. Each group of perforated arc-shaped plates 206 is respectively slidably connected inside each arc-shaped slot 203, and the two perforated arc-shaped plates 206 in each group are in a symmetrical state. The four arc-shaped rods 207 are divided into two groups. Both ends of each group of arc-shaped rods 207 respectively movably penetrate the opposite sides of each group of arc-shaped blocks 205. One end of each arc-shaped clamping rod 208 away from the arc-shaped block 205 is respectively slidably embedded on the surface of each clamping end of the perforated cross-shaped block 202. The four arc-shaped clamping rods 208 are divided into two groups. The opposite ends of each group of arc-shaped clamping rods 208 respectively movably penetrate both sides of the inner wall of each arc-shaped slot 203. A plurality of positioning holes 3 are equidistantly distributed on the outer surface of the valve seat body 1. A semi-circular ring groove 4 is arranged at the bottom of the inner wall of the valve seat body 1. A plurality of oil return holes 5 are equidistantly distributed at the bottom of the inner wall of the valve seat body 1. The inside of each oil return hole 5 is communicated with the inside of the semi-circular ring groove 4. A sealing ring 6 is placed on the top of the inner wall of the valve seat body 1. A compression valve body 7 is movably sleeved between the inside of the sealing ring 6 and the inside of the valve seat body 1. The lower side of the compression valve body 7 is in contact with the top of the sealing ring 6. The top end of the compression valve body 7 is movably sleeved inside the perforated cross-shaped block 202. The bottom of the perforated cross-shaped block 202 is in contact with the upper side of the compression valve body 7.

[0028] The achieved effect is that when the compression valve body 7 needs to be installed on the valve seat body 1, first, the sealing ring 6 is sleeved on the compression valve body 7, and then the compression valve body 7 with the sealing ring 6 is sleeved on the valve seat body 1. Then, one group of two perforated arc-shaped plates 206 is moved towards each other. At this time, the moved group of perforated arc-shaped plates 206 will drive a corresponding group of two arc-shaped clamping rods 208 to move towards each other under the cooperation of a corresponding group of arc-shaped rods 207, a corresponding arc-shaped groove 203, and a corresponding group of arc-shaped blocks 205. At the same time, the moved group of arc-shaped blocks 205 will also compress the spring steel 204 connected to them. When the opposite ends of the moved group of two arc-shaped clamping rods 208 both move into the corresponding arc-shaped groove 203, stop the movement of the group of two perforated arc-shaped plates 206 towards each other. Then, repeat the above operation steps to move the other group of two perforated arc-shaped plates 206 towards each other until the corresponding group of two arc-shaped clamping rods 208 all move into the corresponding arc-shaped groove 203. When the two groups of arc-shaped clamping rods 208 respectively move into the corresponding arc-shaped groove 203, directly sleeve the perforated cross-shaped block 202 on the top of the compression valve body 7. When the four clamping ends of the perforated cross-shaped block 202 are completely butted with the four card slots 201 respectively, the bottom of the perforated cross-shaped block 202 just tightly contacts the upper side of the compression valve body 7. Then, release the force applied to the two groups of perforated arc-shaped plates 206. When the two groups of perforated arc-shaped plates 206 both lose the applied force, at this time, under the cooperation of the two springs 204, the two groups of arc-shaped clamping rods 208 both start to move back to their original positions. When the two arc-shaped clamping rods 208 both return to their initial positions, the end of each arc-shaped clamping rod 208 away from the arc-shaped block 205 connected to it just slides and is embedded on the corresponding clamping end of the perforated cross-shaped block 202 respectively, that is, the perforated cross-shaped block 202 will be tightly fixed on the valve seat body 1. At this time, the installation of the valve seat body 1 and the compression valve body 7 is completed. Then, the valve seat body 1 is installed at the upper end of the working cylinder in the shock absorber through the cooperation of the positioning holes 3. When the shock absorber is put into use on the equipment and is vibrated, at this time, under the cooperation of the spring 204, the arc-shaped groove 203, the arc-shaped block 205, the perforated arc-shaped plate 206, the arc-shaped rod 207, and the arc-shaped clamping rod 208, it can prevent the clamping end of the perforated cross-shaped block 202 from moving out of the corresponding card slot 201, thus ensuring the fixing effect between the valve seat body 1 and the compression valve body 7, that is, preventing the compression valve body 7 from moving out of the valve seat body 1. At the same time, under the action of the sealing ring 6, it can prevent the oil fluid from flowing through the gap between the valve seat body 1 and the compression valve body 7 when the shock absorber is in use. When the shock absorber is converted from the compression state to the recovery state, at this time, under the cooperation of the oil return hole 5 and the semi-circular groove 4, the oil fluid that was squeezed into a specific area during the previous compression stroke can be transported back to its original position.

[0029] Working principle: When the compression valve body 7 needs to be installed on the valve seat body 1, first put the sealing ring 6 on the compression valve body 7, then put the compression valve body 7 with the sealing ring 6 on the valve seat body 1, and then make one group of two perforated arc-shaped plates 206 move towards each other. At this time, the moving group of perforated arc-shaped plates 206 will drive a corresponding group of two arc-shaped clamping rods 208 to move towards each other under the cooperation of a corresponding group of arc-shaped rods 207, corresponding arc-shaped grooves 203 and a corresponding group of arc-shaped blocks 205. At the same time, the moving group of arc-shaped blocks 205 will also compress the spring steel 204 connected to them. When the opposite ends of the moving group of two arc-shaped clamping rods 208 both move into the corresponding arc-shaped grooves 203, stop the two perforated arc-shaped plates 206 in this group from moving towards each other, and then repeat the above operation steps to make the other group of two perforated arc-shaped plates 206 also move towards each other until the corresponding group of two arc-shaped clamping rods 208 all move into the corresponding arc-shaped grooves 203. When the two groups of arc-shaped clamping rods 208 respectively move into the corresponding arc-shaped grooves 203, directly put the perforated cross-shaped block 202 on the top of the compression valve body 7. When the four clamping ends of the perforated cross-shaped block 202 are completely butted with the four clamping grooves 201 respectively, the bottom of the perforated cross-shaped block 202 just tightly contacts the upper side of the compression valve body 7. Then release the force applied to the two groups of perforated arc-shaped plates 206. When the two groups of perforated arc-shaped plates 206 both lose the applied force, at this time, under the cooperation of the two springs 204, the two groups of arc-shaped clamping rods 208 both start to move back to their original positions. When the two arc-shaped clamping rods 208 both return to their initial positions, the end of each arc-shaped clamping rod 208 away from the arc-shaped block 205 connected to it just slides and is embedded on the corresponding clamping end of the perforated cross-shaped block 202 respectively, that is, the perforated cross-shaped block 202 will be tightly fixed on the valve seat body 1. At this time, the installation of the valve seat body 1 and the compression valve body 7 is completed. Then install the valve seat body 1 on the upper end of the working cylinder in the shock absorber through the cooperation of the positioning holes 3. When the shock absorber is put into use on the equipment and is vibrated, at this time, under the cooperation of the spring 204, arc-shaped groove 203, arc-shaped block 205, perforated arc-shaped plate 206, arc-shaped rod 207 and arc-shaped clamping rod 208, it can prevent the clamping end of the perforated cross-shaped block 202 from moving out of the corresponding clamping groove 201, thus ensuring the fixing effect between the valve seat body 1 and the compression valve body 7, that is, preventing the compression valve body 7 from moving out of the valve seat body 1. At the same time, under the action of the sealing ring 6, it can prevent the oil fluid from flowing through the gap between the valve seat body 1 and the compression valve body 7 when the shock absorber is in use. When the shock absorber is converted from the compression state to the recovery state, at this time, under the cooperation of the oil return hole 5 and the semi-circular ring groove 4, the oil fluid squeezed into a specific area during the compression stroke before can be transported back to its original position.

[0030] Among them, both sides of the inner wall of the arc-shaped groove 203 are two end faces inside the arc-shaped groove 203, and the two end faces are respectively close to the inner walls of the corresponding set of clamping grooves 201.

[0031] Among them, the valve seat body 1 and the compression valve body 7 are both prior arts, and their models can be selected according to actual situations and will not be elaborated here.

[0032] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
