DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0022] A first embodiment of the present invention relates to Figures 1 to 5The anti-collision valve mechanism of a multi-pass rack shown in the figure includes a fixed plate 402; the fixed plate 402 is a strip frame structure, a limit pin 403 is inserted and installed in the fixed plate 402, a cam drive 406 is installed at the inner end position of the limit pin 403 in the fixed plate 402, and the limit pin 403 is pressed against the cam drive 406, and a rotating handle 401 is installed outside the fixed plate 402, and the rotating handle 401 coaxially drives the cam drive 406; the fixed plate 402 is installed on the multi-pass rack 1 at the front end position of the layer-changing elevator 3, the limit pin 403 is opposite to the layer-changing elevator 3, and the rear end surface of the layer-changing elevator 3 is provided with a lever 302 to move the rotating handle 401.

[0023] The second embodiment of the present invention is substantially the same as the first embodiment, mainly in that the rotary handle 401 and the cam drive 406 are mounted on a main shaft 405, which is a square shaft.

[0024] Furthermore, a connecting seat 404 is provided on the fixing plate 402 at the position where the limiting pin 403 passes through for guiding and protection.

[0025] Furthermore, a return spring 408 is mounted on the limit pin 403 , and the return spring 408 is located inside the fixing plate 402 and is used for returning the limit pin 403 .

[0026] Furthermore, a transmission plate 407 is connected and fixed to the inner end of the limiting pin 403 , and the cam driving 406 is pressed against the transmission plate 407 .

[0027] Furthermore, a return spring 408 is installed in the connecting seat 404 .

[0028] The third embodiment of the present invention is substantially the same as the first embodiment, mainly in that the lever 302 is fixed at both sides of the inner end of the car 301 of the floor-changing elevator 3 .

[0029] Furthermore, a fixing plate 402 is installed on each of the left and right end surfaces of the multi-pass shelf 1 .

[0030] Furthermore, the installation position of the rotating handle 401 on the main shaft 405 satisfies: when the limit pin 403 is in a state of being pushed out by the cam drive 406, the rotating handle 401 is in a forward movable state; when the fixing plate 402 is in a retracted state without being pushed out, the rotating handle 401 is in a tilted and non-movable state.

[0031] The fourth embodiment of the present invention is combined with the above-mentioned embodiments. The fixed plate 402 is used as the main body to fix the transmission plate 402 and the cam drive 406 on the inside. The rotating handle 401 is connected to the main shaft 405, and the main shaft 405 is driven by the cam drive 406. As the rotating handle 401 rotates, the main shaft 405 rotates, and the cam drive 406 also rotates. The cam drive 406 drives the transmission plate 407 to move backward through rotation, and the transmission plate 407 pulls the limit pin 403 to move backward together. The spring 408 makes the limit pin 403 move forward to reset. In terms of actual installation and use, the safety valve mechanism 4 is fixed to the multi-pass shelf 1 by bolts, and there is a safety valve mechanism 4 on each shelf. After the layer-changing elevator 3 moves up and down, the lever 302 will rotate the rotating handle 401, which can stably realize that the layer-changing elevator 3 opens the limit pin after reaching the specified number of floors, so that the multi-pass car 2 can enter the car 301 of the layer-changing elevator 3.
