The lower surface of the U-shaped block 416 is fixedly connected to a pressure plate 417. The lower surface of the pressure plate 417 is fixedly connected to a damping plate 418.

[0025] The assisting component also includes a constraint unit 42, which includes a positioning frame 421. The positioning frame 421 is fixedly connected to the lower surface of the placement plate 2, and the positioning frame 421 is socketed with the surface of the extension frame 414. The surface of the positioning frame 421 is installed with a linkage frame 422, and the inner wall of the linkage frame 422 is slidingly connected with an extrusion frame 423. The inner wall of the linkage frame 422 is slidingly connected with a fixed frame 424, and the side surface of the fixed frame 424 is fixedly connected with a limiting spring 425. A storage cavity 427 is opened on the side of the extension frame 414 away from the mounting frame 411, and the fixed frame 424 is slidingly connected to the inner wall of the storage cavity 427.

[0026] Specifically, a guide protrusion 426 is fixedly connected to the surface of the fixing frame 424 , and the guide protrusion 426 is slidably connected to the inner wall of the receiving cavity 427 .

[0027] In this embodiment, the position of the fixing frame 424 can be always constrained within the receiving cavity 427 by the cooperation between the guide protrusion 426 and the receiving groove.

[0028] Specifically, a guide block 428 is fixedly connected to the inner wall of the linkage frame 422, and a guide groove 429 is provided on both sides of the extrusion frame 423. The guide block 428 is slidably connected to the inner wall of the guide groove 429. Through the cooperation between the guide block 428 and the guide groove 429, the position of the extrusion frame 423 can be limited within the linkage frame 422.

[0029] In this embodiment, both ends of the first connecting arm 413 are arranged in an arc shape, and both ends of the second connecting arm 415 are arranged in an arc shape.

[0030] In this embodiment, through the cooperation of the connecting arm 1 413 and the connecting arm 2 415 , when the extension frame 414 is in a locked state, the U-shaped frame can be used to press the pressing plate 417 downward.

[0031] Specifically, the connection between the fixing frame 424 and the extrusion frame 423 is chamfered, the fixing frame 424 passes through the side surface of the extension frame 414, and the fixing frame 424 is plugged into the inner wall of the positioning frame 421.

[0034] Working principle: When the cargo rack needs to be moved, step on the squeezing frame 423 downwards. Under the action of the inclined surface of its inner wall, the squeezing frame 423 cooperates with the inclined surface of the fixing frame 424 to push the fixing frame 424. The fixing frame 424 squeezes the limit spring 425. The limit spring 425 is squeezed and deformed. The fixing frame 424 loses the constraint of the limit spring 425 and slides into the storage cavity 427 under force and breaks away from the positioning frame 421. At the same time, the extension frame 414 loses the lock. When the extension frame 414 loses the lock, the operator can use the friction between the foot and the squeezing frame 423 to pull the squeezing frame 423 in the direction away from the placement plate 2. The squeezing frame 423 cooperates with the linkage frame 422 to pull the fixing frame 424. The fixing frame 424 is forced to cooperate with the guide protrusion 426 to pull the extension frame 414, the extension frame 414 pulls the connecting arm 2 415, and the connecting arm 2 415 cooperates with the U-shaped block 416 to pull the pressure plate 417, and then the pressure plate 417 pulls the damping plate 418 upward under the action of the connecting arm 1 413 and the connecting arm 2 415, and the damping plate 418 is pulled off the ground. When the damping plate 418 leaves the ground, the friction between the cargo rack and the ground is weakened, and the cargo rack loses the braking effect of the brake assembly 4, and then the cargo rack can be pushed to move. By setting the brake assembly 4, the staff can stand on one side of the cargo rack to unlock the locked state of the cargo rack, thereby reducing the problem that the staff must unlock the self-locking rollers 3 one by one, which is inconvenient to move the cargo rack, and further improves the convenience of moving the cargo rack.
