The protective plate 16 There are holes 17 on both sides, and the protective plate 16 is used to protect the two sides of the high-pressure plunger pump body 25. Two fixed shells 18 are fixedly connected to the outside of the placement plate 11 on both sides. A telescopic groove 19 is opened on the inner side of the fixed shell 18. A pull rod 20 passes through and is slidably connected in the telescopic groove 19. The limit column 21 is driven to move by the pull rod 20. The inner end of the pull rod 20 is fixedly connected to the limit column 21, and the outer end of the pull rod 20 extends out of the fixed shell 18. A slot plate 22 is arranged on the outside of the fixed shell 18, and a rotating shaft 23 is rotatably connected to the middle part of the slot plate 22. The rotating shaft 23 plays a connecting effect. The outside of the rotating shaft 23 is rotatably connected to the outside of the pull rod 20. A high-pressure plunger pump body 25 is arranged on the top of the placement plate 11.

[0032] Reference Figure 1 The shock absorbing assembly includes a connecting rod 8, both ends of which are fixedly connected to the inside of the movable slot seat 7, and the outside of the connecting rod 8 is slidably connected to two sliders 9, and the two sliders 9 are rotatably connected to the movable rod 10 on the opposite sides, and the top of the movable rod 10 is rotatably connected to the bottom of the placement plate 11, and the two sides of the outside of the connecting rod 8 are fixedly connected to the limiting blocks 13. The shock absorbing assembly can also reduce the vibration generated by the high-pressure plunger pump body 25 when it is working.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A limit pin 6 passes through and is slidably connected in the through hole 3. One end of the limit pin 6 is arranged inwardly in the limit hole 5 to achieve a limiting effect. The fixed shell 18 is arranged on the outside of the insertion hole 17 to facilitate the insertion of the limit column 21 in the fixed shell 18 into the insertion hole 17. The limit column 21 passes through the placement plate 11 and extends out of the slot 15. A spring 24 is sleeved on the outside of the pull rod 20. The spring 24 is arranged in the telescopic groove 19. The limit column 21 can be driven to extend out of the telescopic groove 19 by resetting the spring 24. Two damping springs 12 are sleeved on the outside of the connecting rod 8. The damping spring 12 is arranged between the limit block 13 and the slider 9. The tops of both ends of the connecting rod 8 are fixedly connected with dampers 14, and the top of the damper 14 is fixedly connected to the placement plate 11 to improve the buffering effect.

[0034] Working principle: When the high-pressure plunger pump body 25 needs to be installed, the position of the high-pressure plunger pump body 25 on the moving groove seat 7 is finely adjusted by pushing the moving groove seat 7 so that the slide seat 4 slides in the slide groove 2, so that it can be installed more conveniently. After the position is adjusted, the limit pin 6 is inserted through the through hole 3 into the limit hole 5 on the slide seat 4 to limit the slide seat 4 and prevent it from sliding. When the high-pressure plunger pump body 25 vibrates during operation, the placement plate 11 is pressed down, and the two sliders 9 are squeezed by the two movable rods 10 to move back and forth along the connecting rod 8, squeezing the damping spring 12. At this time, the damping spring 12 is compressed and contracted. When no force is applied, the damping spring 12 is reset, and the dampers 14 on both sides can also disperse the pressure to play a buffering role. The shock-absorbing effect is achieved by protecting the two sides of the high-pressure plunger pump body 25 through the protective plate 16. When the protective plate 16 needs to be disassembled, the slot plate 22 is pushed to rotate the slot plate 22 90°, and the bottom of the slot plate 22 limits the fixed shell 18. At this time, the slot plate 22 rotates along the rotating shaft 23, and then the pull rod 20 can be pulled. The pull rod 20 drives the limiting column 21 to squeeze the spring 24 back into the telescopic slot 19. At this time, the limiting column 21 is separated from the socket 17, and the protective plate 16 can be pulled out of the slot 15. When it needs to be installed, the protective plate 16 is inserted into the slot 15, and the slot plate 22 is pushed in the opposite direction. The spring 24 is reset, driving the limiting column 21 to extend from the telescopic slot 19 and insert into the socket 17 of the protective plate 16.
