[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0028] This embodiment provides a technical solution:

[0029] Please see Figures 1-5 As shown, the shock-absorbing support device for the torque sensor includes two symmetrical support plates 10 fixedly installed at the bottom of the torque sensor body 1. A mounting plate 11 is fixed between the bottom ends of the two support plates 10. Two limiting grooves 110 are provided at both the front and rear ends of the mounting plate 11. A shock-absorbing and fastening mechanism 2 is provided below the mounting plate 11. The shock-absorbing and fastening mechanism 2 includes a base 20. A shock-absorbing plate 21 is fixed at the bottom of the base 20, and a mounting bracket 22 is fixed at the top of the base 20. The top of the mounting bracket 22 is... Two sliding grooves 220 are provided at both the front and rear ends; the bottom of the mounting bracket 22 is open, and a double-ended lead screw 23 is rotatably installed in the bottom opening of the mounting bracket 22. Both ends of the double-ended lead screw 23 are threadedly connected to a horizontally movable connecting seat 26. Two limiting rods 27 are fixed on the top of the connecting seat 26. The limiting rods 27 pass through the sliding grooves 220 and are inserted into the limiting grooves 110, and the limiting rods 27 abut against the end of the limiting grooves 110; a limiting block 28 is coaxially fixed on the top of the limiting rods 27.

[0030] In this embodiment, the mounting bracket 22 has a U-shaped cross-section and is tightly welded to the base 20. The U-shaped design and tight welding enhance the stability of the connection and prevent loosening or separation during installation.

[0031] In this embodiment, the limiting rod 27 and the limiting block 28 are integrally formed, with the diameter of the limiting block 28 being larger than the diameter of the limiting rod 27. This integrally formed structure enhances the strength and durability of the limiting rod 27 and the limiting block 28, preventing malfunctions caused by loosening or breakage at the connection point. The larger diameter of the limiting block 28 provides better limiting effect and stability, preventing the mounting plate 11 from detaching from the limiting rod 27.

[0032] In this embodiment, the dimensions of the limiting rod 27 are adapted to the dimensions of the limiting groove 110. The end of the limiting groove 110 has an overall arc shape, while the limiting rod 27 has an overall cylindrical shape. This size adaptation ensures smooth movement and precise positioning of the limiting rod 27 within the limiting groove 110. The arc-shaped end reduces friction and resistance during movement, improving the smoothness and efficiency of operation, while also ensuring the limiting rod 27's limiting and fixing effect on the mounting plate 11.

[0033] In this embodiment, two guide rods 25 are also bolted to the bottom opening of the mounting bracket 22. The guide rods 25 pass through the connecting seat 26 and are slidably connected to it. The design of the guide rods 25 provides additional support and guidance, ensuring the stability and accuracy of the connecting seat 26 during movement. The bolted connection enhances the connection strength between the guide rods 25 and the mounting bracket 22, improving the reliability of the overall structure.

[0034] In this embodiment, the threads at both ends of the double-ended lead screw 23 have opposite directions of rotation, and the ends of the double-ended lead screw 23 are rotatably connected to the inner wall of the mounting bracket 22 via bearings. The design of opposite thread directions facilitates driving the two connecting seats 26 to move in opposite directions, improving operational flexibility and efficiency. The rotatable bearing connection reduces friction and wear, extending the service life of the double-ended lead screw 23.

[0035] In this embodiment, the front end of the double-ended lead screw 23 passes through the outer wall of the mounting bracket 22. An adjusting handle 24 is coaxially keyed to the front end of the double-ended lead screw 23. The outer wall of the adjusting handle 24 has multiple anti-slip grooves. The adjusting handle 24 provides a convenient manual operation method, and the coaxial key connection ensures a secure connection between the adjusting handle 24 and the double-ended lead screw 23. The anti-slip grooves increase friction during gripping, preventing slippage and loss of control during operation.

[0036] In this embodiment, the shock-absorbing plate 21 has a rectangular cross-sectional shape and is a rivet rubber shock-absorbing pad. The rectangular cross-sectional shape provides better structural stability and support. The rivet rubber material has excellent elasticity and resilience, as well as good wear resistance and durability. Using this shock-absorbing pad can effectively absorb and disperse vibration and impact energy from equipment or the environment, thereby reducing the impact of noise and vibration on the torque sensor body 1.

[0037] It should be added that the base 20 in this embodiment has mounting holes 200 at both the front and rear ends. The mounting holes 200 are designed to facilitate the insertion of bolts, allowing the equipment to be installed and fixed to the ground or a fixed platform by bolts, thus ensuring the reliability and stability of the equipment installation.

[0038] In addition, the bottom of the limiting block 28 in this embodiment abuts against the top of the mounting plate 11. This design ensures that the mounting plate 11 will not wobble after it is fixed, thus guaranteeing the installation stability of the mounting plate 11 and the torque sensor body 1.

[0039] When installing the torque sensor body 1, the user first places the mounting plate 11 on top of the mounting bracket 22, aligning the limiting groove 110 with the limiting rods 27 on both sides. Then, the user rotates the adjusting handle 24, which drives the double-ended lead screw 23 to rotate. Since the connecting seat 26 is threadedly connected to the double-ended lead screw 23, the two connecting seats 26 move inward in sync. The connecting seats 26 simultaneously drive the limiting rods 27 and the limiting blocks 28 to move. The limiting rods 27 slide along the slide groove 220 and the limiting groove 110. When the limiting rods 27 on both sides are pressed against the end of the limiting groove 110, the user stops rotating the adjusting handle 24. At this time, the mounting plate 11 is fixed to the mounting bracket 22, and the torque sensor body 1 is installed.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
