Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0029] With reference to Figures 1-5 , the utility model provides an embodiment:

[0030] The utility model provides an oil pressure valve of impact resistance, including valve body 1, be provided with anti -impact mechanism 2 in valve body 1, anti -impact mechanism 2 includes fixed column 204 and two buffer blocks 213, one side fixedly arranged with connecting ball 201 of fixed column 204, the other side fixedly arranged with spring 206 of fixed column 204, a plurality of rotating blocks 202 are rotationally arranged outside fixed column 204, two two opposite sides of a plurality of rotating blocks 202 are rotationally arranged with sliding block 209, two two opposite sides of a plurality of sliding blocks 209 are fixedly arranged with connecting rod 210, two two opposite sides of a plurality of connecting rods 210 are fixedly arranged with sliding plate 203, the side away from connecting ball 201 of spring 206 is fixedly arranged in the one side close to fixed column 204 in valve body 1, fixed column 204 is slidably arranged in the one side close to connecting ball 201 in valve body 1, a plurality of sliding blocks 209 are slidably arranged in the one side away from connecting ball 201 in valve body 1, the one side of connecting ball 201 is arranged in the one side away from fixed column 204 in valve body 1, two two opposite sides of a plurality of sliding plates 203 are rotationally arranged with rotating plate 208, a plurality of buffer grooves 205 are formed in the one side close to rotating plate 208 in valve body 1, a plurality of sliding grooves 207 are formed in the one side close to buffer groove 205 in valve body 1, a plurality of sliding plates 203 are slidably arranged in a plurality of sliding grooves 207 respectively outside;

[0031] Specifically, when the oil pressure valve encounters impact, the impact force first acts on the connecting ball 201, causing the connecting ball 201 to move the fixed column 204 towards the spring 206, thereby causing the spring 206 to contract. The movement of the connecting ball 201 increases the distance between it and the inner wall of the valve body 1, providing more space for the flow of liquid. As the fixed column 204 moves, the rotating blocks 202 arranged around it begin to rotate. The rotation of the rotating blocks 202 causes the sliding blocks 209 connected to them to slide in opposite directions within the valve body 1. At the same time, the connecting rods 210 also slide synchronously. The sliding of the connecting rods 210 further causes the sliding plates 203 to slide within the sliding grooves 207. The change in distance caused by the sliding of the sliding plates 203 expands the flow path for the liquid, allowing it to pass through the valve more quickly and reducing pressure fluctuations caused by liquid stagnation. When the liquid is impacted, it will push the rotating plates 208 to rotate within the sliding plates 203. The rotating process of the rotating plates 208 effectively disperses and consumes impact energy, reducing the impact on the internal structure of the valve body 1 and ensuring the stability of the valve body 1.

[0032] Reference Figures 1-7The valve body 1 is internally rotatably provided with a valve plate 214 away from one side of the connecting ball 201, two first inclined blocks 215 are slidably arranged in the valve plate 214, two second inclined blocks 216 are fixedly arranged on the opposite side of the two buffer blocks 213, the two second inclined blocks 216 are slidably arranged in the valve plate 214, the opposite sides of the two second inclined blocks 216 are slidably arranged on the opposite sides of the two first inclined blocks 215, the upper ends of the two first inclined blocks 215 are fixedly provided with compression springs 212, the upper ends of the two compression springs 212 are fixedly arranged in the valve plate 214, two guide grooves 217 are formed in the two sides of the valve plate 214, a plurality of guide rods 211 are fixedly arranged on the opposite sides of the two buffer blocks 213, and the plurality of guide rods 211 are slidably arranged in the guide grooves 217; and the upper end of the valve body 1 is rotatably provided with a rotating ring 3, and the lower end of the rotating ring 3 is fixedly arranged on the upper end of the valve plate 214.

[0033] Specifically, when the buffer block 213 is impacted, the second inclined block 216 and the guide rod 211 connected thereto will slide in the valve plate 214, the guide rod 211 will slide in the guide groove 217, and the stability of the movement of the buffer block 213 can be ensured, the sliding of the second inclined block 216 will push the first inclined block 215 to slide upward in the valve plate 214, and the sliding of the first inclined block 215 will press the compression spring 212 connected thereto, so that the compression spring 212 is contracted in the valve plate 214. The side of the buffer plate is spherical in shape. Such a spherical structure can more evenly disperse the impact force when impacted, avoid local stress concentration, further improve the buffering effect, and to some extent, reduce the wear of the surrounding parts. Through the cooperative operation of multiple parts, the impact energy is effectively dispersed and absorbed, the reliability of the oil pressure valve under high impact working conditions is improved, and the service life is prolonged.

[0034] Working principle: when the oil pressure valve is impacted, the impact first acts on the connecting ball 201, the connecting ball 201 transmits the impact force to the fixed column 204, the fixed column 204 moves to the spring 206 under the action of the impact force, and the spring 206 is compressed, the movement of the connecting ball 201 will make the distance between the connecting ball 201 and the inner wall of the valve body 1 larger, so that the liquid can flow faster, with the movement of the fixed column 204, the rotating block 202 outside the fixed column 204 will rotate, the rotation of the rotating block 202 will promote the opposite sliding of the sliding block 209 in the valve body 1, and synchronously make the connecting rod 210 slide, the sliding of the connecting rod 210 will drive the sliding plate 203 to slide in the sliding groove 207, the sliding of the sliding plate 203 will increase the distance, so that the liquid can pass through more quickly, and the impact of the liquid will make the rotating plate 208 rotate in the sliding plate 203, thereby effectively reducing the influence of the impact on the inside of the valve body 1;

[0035] Second, when the buffer block 213 is impacted, it will drive the second inclined block 216 and the guide rod 211 connected with it to slide inside the valve plate 214, the sliding of the second inclined block 216 will push the first inclined block 215 to slide upwards inside the valve plate 214, the sliding of the first inclined block 215 will extrude the compression spring 212 connected with it, causing it to contract inside the valve plate 214, further reducing the impact on the oil pressure valve.

[0036] Finally, it should be noted that: the above only for the preferred embodiments of the present application and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
