[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-7 The utility model provides a technical solution: a clamping device is provided on a refrigerator lifting device for clamping a freezing shelf body 5, comprising a mounting base 1 provided on the lifting device and a power device 2 provided on the mounting base 1, and further comprising:

[0026] The transmission device 3 is arranged on the mounting base 1 and connected to the power device 2;

[0027] Four clamping claws 4 are provided and are arranged at equal angles at the lower end of the transmission device 3 to clamp and fix the freezing rack body 5.

[0028] The lifting device drives the mounting base 1 to move, and then moves the clamping jaws 4 to the freezing rack body 5. Then, the mounting base 1 is installed at the lower end of the lifting device of the refrigerator. The lifting device drives the mounting base 1 to move, and then moves the clamping jaws 4 to the freezing rack body 5. Then, the installation position of the clamping jaws 4 is adjusted, and the clamping jaws 4 are moved to the outside of the freezing rack body 5. Then, the power device 2 is started to drive the transmission device 3 to move. The transmission device 3 drives the clamping jaws 4 to clamp and fix the freezing rack body 5. A single power device 2 performs synchronous movement of the clamping jaws 4 in four directions, which can effectively grasp and position the freezing rack body 5. The structure is simple and has high stability. The four clamping jaws 4 are set at equal angles, which can evenly distribute the clamping force and ensure that the freezing rack body 5 is stable and does not shake during the lifting process. Through the design of the transmission device 3, the opening and closing range of the clamping jaws 4 is adjustable, which can easily adapt to freezing rack bodies 5 of different sizes and shapes without replacing parts or making complicated adjustments, thereby improving the versatility and flexibility of the equipment.

[0029] In one embodiment, the mounting base 1 includes a side panel 11, a top panel 13 fixed to the upper inner end of the side panel 11, a base 14 fixed to the lower inner end of the side panel 11, and a support panel 12 fixed to the portion of the side panel 11 between the top panel 13 and the base 14, and the transmission device 3 is mounted on the base 14.

[0030] With this design, the top plate 13 provides installation space for the power device 2, and the base 14 provides installation space for the transmission device 3. The design of the support plate 12 makes the power device 2 more firmly installed, forming a stable frame structure, which not only improves the overall mechanical strength, but also can effectively disperse and withstand the various forces and vibrations generated from the transmission device 3 and the clamping process, ensuring the long-term stable operation of the clamping device.

[0031] In one embodiment, the power device 2 includes a motor 21 fixed to the upper end of the top plate 13, a rotating shaft 22 arranged at the power output end of the motor 21 and passing through the top plate 13 and the support plate 12, and a connecting member arranged at the lower end of the rotating shaft 22, and the connecting member is connected to the transmission device 3.

[0032] In this design, the motor 21 serves as a power source, driving the rotating shaft 22 to rotate the rod, and then driving the connecting piece at the lower end of the rotating shaft 22 to move, so that the transmission device 3 drives the clamping claw 4 to move, clamping and fixing the freezing rack body 5. The rotating shaft 22 ensures that the power can be transmitted to the connecting piece smoothly and without loss, thereby driving the transmission device 3.

[0033] In one embodiment, the connecting member includes a rotating disk 23 arranged at the lower end of the rotating shaft 22, a transmission rod 24 arranged at an equal angle on the rotating disk 23, a pushing block 25 arranged at the lower end of the transmission rod 24, and a pushing rod 26 fixed to the lower end of the pushing block 25 away from the rotating disk 23. The pushing block 25 is arranged in an L shape.

[0034] With this design, the transmission rod 24 is fixed at an equal angle to the lower end of the rotating disk 23, the pushing block 25 is rotatably sleeved on the lower end of the transmission rod 24, and the pushing rod 26 is rotatably sleeved on the lower end of the pushing block 25. The rotating disk 23 drives the transmission rod 24 to rotate along the center of the rotating shaft 22, so that the pushing block 25 pulls the pushing rod 26 to move, and then drives the transmission device 3 to move on the base 14. This design ensures that power can be evenly transmitted from the rotating shaft 22 to each transmission rod 24. This evenly distributed power transmission method improves the operating stability of the equipment. The design of the L-shaped pushing block 25 makes the transmission path more optimized. Its L-shaped structure is not only convenient for docking with the transmission device 3, but also can achieve effective power transmission in a limited space.

[0035] In one embodiment, the transmission device 3 includes a connecting block 31 arranged at the lower end of the push rod 26, a slider 32 fixed to the lower end of the connecting block 31, a slide rail 33 arranged at an equal angle at the upper end of the base 14, and a clamping rod 34 fixed to the lower end of the connecting block 31. The slider 32 is slidably arranged on the slide rail 33, and a sliding groove 1401 for the clamping rod 34 to move is opened at the position of the base 14 corresponding to the clamping rod 34, and the clamping claw 4 is fixed to the lower end of the clamping rod 34.

[0036] With this design, the connecting block 31 serves as a connecting component between the push rod 26 and the slider 32. During the movement, the push rod 26 drives the connecting block 31 to move on the slide rail 33, drives the clamping rod 34 to move in the sliding groove 1401, and then drives the clamping jaws 4 to fix the freezing rack body 5. Its stable structure ensures the accuracy and reliability of power transmission, further improves the stability and precise positioning capability of the transmission, and the clamping jaws 4 are fixed to the lower end of the clamping rod 34 and directly contact the clamped object. By adjusting the position of the clamping rod 34 and the shape of the clamping jaws 4, stable and reliable clamping of freezing rack bodies 5 of different shapes and sizes can be achieved, thereby improving the practicality and versatility of the clamping device.

[0037] In one embodiment, a stabilizing plate 36 is fixed to the clamping rod 34 , a laser sensor 15 is provided at the lower end of the base 14 , and a pressure sensor 35 is provided on the clamping jaw 4 .

[0038] With this design, the fixation of the stabilizing plate 36 increases the rigidity and stability of the clamping rod 34, and can prevent the clamping rod 34 from bending or deforming due to uneven force, thereby ensuring the accuracy and reliability of clamping. The pressure sensor 35 on the clamping jaw 4 can monitor the clamping force in real time to ensure that the clamping is neither too tight nor too loose, avoiding damage or falling off caused by improper clamping. The laser sensor 15 can emit a laser beam and receive the reflected signal, which can realize the precise positioning of the clamping device and ensure that the clamping jaw 4 can accurately grasp the freezing rack body 5.
