[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1:

[0020] Please see Figures 1 to 4As shown, an adjustable reaction wall / reaction platform includes an adjusting bracket 1, a lifting plate 2 above the adjusting bracket 1, a base 3 fixedly connected to the top of the lifting plate 2, a hydraulic cylinder 4 fixedly connected to one side of the top of the base 3, a fifth movable clamp fixedly connected to the output end of the hydraulic cylinder 4, a connecting rod 5 hinged to the surface of the fifth movable clamp, a first movable clamp 8 fixedly connected to the other side of the top of the base 3, a reaction wall 6 hinged to the surface of the first movable clamp 8, a second movable clamp 7 slidably connected to one side of the reaction wall 6, and one end of the connecting rod 5 hinged to the surface of the second movable clamp 7. Two placement platforms 9 are fixedly connected to the top and bottom of one side of the reaction wall 6, and a protective shell 1 is fixedly connected to the middle of one side of the adjusting bracket 1. 0. A servo motor 11 is fixedly connected inside the protective shell 10. A rotating rod 12 is fixedly connected to the output end of the servo motor 11. Two sets of reverse threads 25 are opened on the surface of the rotating rod 12. A threaded sleeve 13 is threaded through the surface of the reverse threads 25. A third movable clamp 14 is fixedly connected to the surface of the threaded sleeve 13. A lifting rod 15 is hinged to the surface of the third movable clamp 14. Two lifting blocks 16 are arranged above the adjusting bracket 1. A fourth movable clamp 17 is fixedly connected to both sides of the bottom of the lifting block 16. The bottom end of the lifting rod 15 is hinged to the surface of the fourth movable clamp 17. A square seat 18 is fixedly connected to the top of the lifting block 16. The top of the square seat 18 is fixedly connected to the bottom of the base 3. The lifting plate 2 raises the base 3 and the structure above it by a certain distance. The hydraulic cylinder 4 and the fifth movable clamp push the connecting rod 5 a certain distance and simultaneously hinge it at a certain angle. The first movable clamp 8 allows the reaction wall 6 to be adjusted at a certain angle. The hydraulic cylinder 4 pushes the connecting rod 5, adjusting the angle between the reaction wall 6 and the first and second movable clamps 8 and 7. The servo motor 11 provides a driving force for the rotation of the rotating rod 12. The placement platform 9 secures the testing equipment. The rotating rod 12 allows the reverse threads 25 to be opened; two reverse threads 25 form a group, with two groups in total. Each set of reverse threads 25 has two threads in opposite directions, keeping the threaded sleeves 13 moving towards or away from each other. By rotating the rotating rod 12, the reverse threads 25 rotate in the opposite direction, causing the threaded sleeves 13 to move towards each other, which in turn causes the third movable clamp 14 to move towards each other. Through the setting of the third movable clamp 14, one end of the lifting rod 15 can be hinged to it. When the threaded sleeves 13 move towards each other, they drive the third movable clamp 14 to move towards each other, which in turn causes the two lifting rods 15 to move towards each other. Thus, the bottom end of the lifting rod 15, through the hinge with the fourth movable clamp 17, lifts the lifting block 16 a certain distance, thereby causing the square seat 18 to move upward, and finally causing the base 3 to move upward, so that the height of the reaction wall 6 is adjusted.

[0021] A control panel is fixedly connected to one side of the surface of the adjustment bracket 1, and the control panel is electrically connected to the hydraulic cylinder 4 and the servo motor 11 respectively.

[0022] Example 2:

[0023] Please see Figure 1 and Figure 2 As shown, a slide rail 21 is fixedly connected to the center of the top of the base 3. A sliding seat 22 is fixedly connected inside the slide rail 21. A support platform 23 is fixedly connected to the top of the sliding seat 22. A connecting rod 24 is fixedly connected to the center of the top of the support platform 23, and the top end of the connecting rod 24 is fixedly connected to the surface of the connecting rod 5. The slide rail 21 allows the sliding seat 22 to slide on its surface. The sliding seat 22 fixes the support platform 23 to its top. The support platform 23 fixes the connecting rod 24. The connecting rod 24 makes the connecting rod 5 more stable during movement. The lateral movement of the connecting rod 5 allows the sliding seat 22 to move on the slide rail 21, maintaining stability during movement.

[0024] The inner bottom wall of the adjusting bracket 1 is provided with two sets of limiting grooves 20. Limiting blocks are slidably connected inside the limiting grooves 20, and limiting rods 19 are fixedly connected to the top of the limiting blocks. The top of the limiting rods 19 is fixedly connected to the surface of the threaded sleeve 13. The limiting grooves 20 allow the limiting blocks to slide inside them, and the limiting rods 19 are fixed to their tops. The limiting rods 19 provide a certain limiting effect when the threaded sleeve 13 moves.

[0025] A protective frame 26 is fixedly connected to the top of the base 3, and several mounting holes are provided inside the base 3. The protective frame 26 provides protection for the hydraulic cylinder 4 and the slide rail 21.

[0026] The working principle of this utility model is as follows: The operator controls the hydraulic cylinder 4 to work in advance. The output end of the hydraulic cylinder 4 drives the connecting rod 5 to move to the right. Then, the connecting rod 5 pushes the reaction wall 6 to the right through the hinge with the second movable clamp 7 and the fifth movable clamp. During this process, the bottom of the reaction wall 6 rotates to the right through the hinge with the first movable clamp 8. Then, its angle is adjusted and the overall height is gradually raised. At this time, the operator can also control the servo motor 11 to work as needed. The output end of the servo motor 11 drives the rotating rod 12 to rotate. Then, the two sets of threaded sleeves 13 on its surface move towards each other, thereby causing the third movable clamp 14 to move towards each other. Then, it drives the lifting rod 15 to move towards each other. Then, one end of the lifting rod 15 lifts the lifting block 16 and the square seat 18 through the hinge with the fourth movable clamp 17. Finally, the height of the lifting plate 2 and the base 3 is adjusted. At this time, the height of the reaction wall 6 is adjusted again, which is convenient for testing according to the needs of the operator.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
