[0021] The utility model provides Figure 1 to Figure 3 A load cabinet with a protective function shown in the figure comprises a load cabinet body 1 . Moving wheels 5 are arranged at four corners of the bottom end of the load cabinet body 1 . The load cabinet body 1 can be moved and transported by the moving wheels 5 .

[0022] Two sliding grooves 2 are provided on both sides of the load cabinet 1. The two sliding grooves 2 are distributed parallel to the ground, and the two sliding grooves 2 are respectively arranged at the bottom and the top of one side of the load cabinet 1. Slide blocks 3 are slidably connected in the two sliding grooves 2. The two slide blocks 3 are fixedly connected to the side away from the load cabinet 1 with dampers 10. A protective plate 4 is fixed at one end of the two dampers 10. A connecting seat 6 is fixed at the bottom end of the protective plate 4. The protective plate 4 and the connecting seat 6 are both arranged in a U shape, and the U-shaped opening of the protective plate 4 is arranged toward the load cabinet 1.

[0023] A threaded rod 7 is rotatably connected to the connecting seat 6, the bottom end of the threaded rod 7 extends out of the connecting seat 6, and a suction cup 8 is fixed to the bottom of the extended end, an auxiliary handle 11 is provided at the top of the threaded rod 7, and the bottom end of the suction cup 8 is adsorbed and connected to the ground.

[0024] In the actual operation of the present invention, the user can pull the load cabinet 1 to move through the U-shaped protective plate 4. The protective plate 4 can provide hand support for the user. At the same time, the protective plate 4 can protect the outside of the load cabinet 1. When the load cabinet 1 is hit, the cooperation between the protective plate 4 and the damper 10 can buffer the impact force and prevent the impact force from directly acting on the load cabinet 1, causing vibration damage to the internal structure.

[0025] And the protection plate 4 can slide in the sliding groove 2 as needed, so as to change the position that needs to be protected. When the position is determined, the threaded rod 7 can be rotated downward so that the suction cup 8 at the bottom of the threaded rod 7 can be squeezed and adsorbed with the ground in the laboratory to complete the position of the protection plate 4. At the same time, when the suction cup 8 completes the adsorption, the position of the load cabinet 1 is also fixed to prevent the load cabinet 1 from moving.
