In the utility model, the refrigeration equipment is placed inside the lifting frame by means of the servo motor, the clamping plate and the threaded sleeve, and the servo motor is started to drive the threaded rod to rotate. The threaded rod drives the threaded sleeve to rotate through the symmetrical external threads arranged on the outer wall of the threaded rod and the internal threads arranged on the inner wall of the threaded sleeve. The threaded sleeve is limited by the limiting block and the limiting groove, so that the threaded sleeve moves to the middle position along the trajectory of the limiting groove, and at the same time drives the clamping plate to clamp and fix both sides of the refrigeration equipment. This structure can quickly clamp and fix both sides of the equipment to prevent the equipment from falling due to instability during lifting, and the operation is simple and safe.

[0027] In this embodiment, a notch is provided on the outer wall of one side of the outer telescopic rod 3 , and the notch matches the gear 6 .

[0028] In this embodiment, the outer diameter of the inner telescopic rod 11 is the same as the inner diameter of the outer telescopic rod 3 , and tooth blocks are arranged at equal intervals on the outer wall of the inner telescopic rod 11 .

[0029] In this embodiment, the cross section of the lifting frame 7 is rectangular, and movable grooves are formed at equal intervals on the outer walls of both sides of the lifting frame 7 .

[0030] Specific as Figure 1 , Figure 2 and Figure 5As shown, when using this structure, the refrigeration equipment is placed inside the lifting frame 7, the hydraulic cylinder 5 is started to push the tray 12 and pull the inner telescopic rod 11 up at the same time, and the gear 6 is driven to rotate by the meshing transmission of the inner telescopic rod 11 and the gear 6. When the weight of the equipment on both sides of the lifting frame 7 is uneven, the pressure on one side of the lifting frame 7 increases, and the heavier side of the lifting frame 7 is supported by reinforcing the inner telescopic rod 11. The inner telescopic rod 11 is calibrated by the bearing 18 and the gear 6 to make the rising height consistent, so that the lifting force on both sides of the bottom of the lifting frame 7 is consistent, so as to avoid the lifting frame 7 from tilting to one side after being used for too long. At the same time, when the hydraulic cylinder 5 fails, the inner telescopic rod 11 and the gear 6 are meshed and transmitted to reduce the weight of a part of the equipment, which can effectively slow down the descent speed of the lifting frame 7, avoid equipment damage and ensure the safety of the staff.

[0031] Embodiment 2: A servo motor 13 is installed on the outer wall of the equipment bin 16 , and a threaded rod 14 is connected to the output shaft of the servo motor 13 . One end of the threaded rod 14 penetrates through the outer wall of the equipment bin 16 and is movably installed on the inner wall of the equipment bin 16 .

[0032] In this embodiment, the outer wall of the threaded rod 14 is symmetrically provided with external threads, the outer wall of the threaded rod 14 is symmetrically and movably installed with a threaded sleeve 15, the side wall of the threaded sleeve 15 is installed with a limit block 8, and the outer wall of the limit block 8 is installed with a clamping plate 9.

[0033] In this embodiment, the cross section of the limiting block 8 is rectangular, and the limiting block 8 and the limiting groove 10 match each other.

[0034] In this embodiment, the inner wall of the threaded sleeve 15 is provided with internal threads, and the internal threads provided on the inner wall of the threaded sleeve 15 match the external threads provided on the outer wall of the threaded rod 14 .

[0035] Specific as Figure 1 , Figure 3 and Figure 4 As shown, when this structure is used, the refrigeration equipment is placed inside the lifting frame 7, and the servo motor 13 is started to drive the threaded rod 14 to rotate. The threaded rod 14 drives the threaded sleeve 15 to rotate through the symmetrical external threads set on the outer wall of the threaded rod 14 and the internal threads set on the inner wall of the threaded sleeve 15. The threaded sleeve 15 is limited by the limit block 8 and the limit groove 10, so that the threaded sleeve 15 moves to the middle position along the trajectory of the limit groove 10, and at the same time drives the clamping plate 9 to clamp and fix both sides of the refrigeration equipment. This structure can quickly clamp and fix both sides of the equipment to prevent the equipment from falling due to instability during lifting, and the operation is simple and safe.

If the equipment is heavy, it can be tied and reinforced for a second time through the movable grooves set on both sides of the lifting frame 7, and the hydraulic cylinder 5 is started to lift the inner wall through the hydraulic cylinder 5. The telescopic rod 11 is stretched on the inner wall of the outer telescopic rod 3, so that the inner telescopic rod 11 meshes with the gear 6 during stretching, and the gear 6 is limited by the fixed block 17 and the bearing 18 to keep it at the same level, ensuring that the inner telescopic rods 11 on both sides are stretched upward by the same distance and synchronously lift the bottom end of the lifting frame 7 with the tray 12 to avoid the different weights of the equipment on the left and right sides of the lifting frame 7, causing the lifting frame 7 to tilt, so that the two sides of the bottom end of the lifting frame 7 are always lifted by the same force, and at the same time, when the hydraulic cylinder 5 fails, the lifting frame 7 is prevented from falling quickly, damaging the equipment and injuring the staff. The structure can also keep the equipment firmly clamped during lifting to avoid shaking of the equipment and causing safety hazards.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
