[0024] As shown Figures 1-8 in the figure, a middle door interlock chassis truck includes a frame 100. A drive shaft 110 for moving the frame 100 and penetrating the frame 100 is arranged inside the frame 100. One end of the drive shaft 110 is provided with a connecting portion 111 for cooperating with a handle 200. A baffle 300 for preventing the handle 200 from being inserted into the connecting portion 111 is arranged on the frame 100 at a position relative to the connecting portion 111. A locking device 400 for unlocking and locking the baffle 300 is also included. In the unlocked state, the frame 100 is moved by inserting the handle 200 into the connecting portion 111. In the locked state, the baffle 300 always blocks in front of the connecting portion 111, so that the handle 200 cannot be inserted. When the cabinet door is closed, it is equivalent to pressing the rotating block 420 in. The rotating block 420 makes the baffle 300 move away through the transmission block 430, and then it enters the unlocked state. The handle 200 can be inserted, and the frame 100 can be moved by rotating the handle 200.

[0025] The number of the baffle 300 and the locking device 400 is two, and they are respectively arranged on both sides of the connecting portion 111. The two baffles 300 realize the mutual conversion between the locked state and the unlocked state through the forward and backward movement paths. The number of the baffle 300 can be one, which can block the connecting portion 111. However, in this application, the preferred number is two, which combines practicality.

[0026] The locking device 400 includes a fixed seat 410 for being assembled on the frame 100. A rotating block 420 for forcing the baffle 300 to move is arranged inside the fixed seat 410. The rotating block 420 is rotatably connected to the fixed seat 410. The baffle 300 realizes reciprocating movement through the rotation of the rotating block 420 on the fixed seat 410. The fixed seat 410 can be fixed to the side part of the frame 100 by screws.

[0027] A transmission block 430 is arranged between the rotating block 420 and the baffle 300. The transmission block 430 is rotatably connected to the fixed seat 410. The rotating block 420 drives the baffle 300 through the transmission block 430. The rotating block 420 and the transmission block 430 can be rotatably connected to the fixed seat 410 through a pin shaft (not shown in the figure).

[0028] A first convex block 431 for forcing the baffle 300 to move is arranged on the transmission block 430. A blocking portion 310 for cooperating with the first convex block 431 is arranged on the baffle 300. The transmission cooperation between the transmission block 430 and the baffle 300 is realized through the first convex block 431 and the blocking portion 310.

[0029] The rotating block 420 is provided with a protrusion 421 for driving the movement of the transmission block 430. The transmission block 430 is provided with a second protrusion 432 that cooperates with the protrusion 421. The transmission cooperation between the rotating block 420 and the transmission block 430 is achieved through the protrusion 421 and the second protrusion 432.

[0030] The fixed seat 410 is provided with a guiding groove 411 for limiting the reciprocating movement of the baffle 300. The baffle 300 is provided with a guiding block 320 that cooperates with the guiding groove 411. The limiting reciprocating movement between the fixed seat 410 and the baffle 300 is achieved through the cooperation of the guiding groove 411 and the guiding block 320, and the baffle 300 performs a limiting reciprocating movement within the guiding groove 411.

[0031] An elastic structure 412 for forcing the baffle 300 to prevent the handle 200 from being inserted is provided within the guiding groove 411. The elastic structure 412 preferably adopts a spring structure, which is convenient for assembly and has a low cost.

[0032] A cut groove 330 for facilitating the insertion of the handle 200 into the connecting portion 111 is provided at the end of the baffle 300. The cut groove 330 can be designed to be semi-circular. By combining two baffles 300, a circular groove is formed. Due to the space limitation on the side of the chassis truck, the baffle 300 cannot move to a large extent. After adding this cut groove 330, the stroke of the baffle 300 can be greatly shortened, and it has strong practicability.

[0033] The rotating block 420 is provided with a roller 422 for facilitating the rotation of the rotating block 420. The roller 422 is rotatably connected to the rotating block 420. The roller 422 is used in cooperation when the middle door of the cabinet is closed. After the middle door is closed, it will press the rotating block 420 to rotate, thereby moving the baffle 300 away so that the handle 200 can be inserted into the connecting portion 111. Adding the roller 422 can facilitate the cooperation with the cabinet door and has strong practicability.

[0034] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, simple modifications and substitutions by ordinary technicians in the field are within the protection scope of the present utility model.
