The end of the cylinder 11 is rotatably connected to one end of the top of the scissor-type bracket 8, and the edge of the plug-in door 19 is slidably engaged with the horizontal bar 9. Starting the cylinder 11 drives one end of the top of the scissor-type bracket 8 to move inside the slide groove 2 10, thereby driving the height of the scissor-type bracket 8 to be adjusted. At this time, one end of the bottom of the scissor-type bracket 8 will slide inside the slide groove 1 7, which can drive the height of the plug-in door 19 to be adjusted, thereby controlling the opening and closing of the plug-in door 19.

[0023] Among them, the bottom of the side rail 3 is slidably plugged with an insertion rod 4, the top of the insertion rod 4 is fixedly connected to a pad 5, and the surface of the insertion rod 4 is movably sleeved with a spring 6. The bottom end of the spring 6 abuts against the inner bottom of the side rail 3, and the top of the spring 6 abuts against the lower surface of the pad 5. When the plug-in door 19 is closed, the bottom end of the plug-in door 19 will fall directly onto the pad 5, and the weight of the plug-in door 19 will be applied to the spring 6, so that the impact generated by the plug-in door 19 when closing is applied to the spring 6, thereby protecting the side rail 3.

[0024] Among them, the upper part of the two side edges of the plug-in door 19 is provided with a limit hole 12, and the bottom of the two side edges of 19 is provided with a limit hole 2 13. The side of the side rail 3 is fixedly connected to the limit frame 14, and the inner wall of the limit frame 14 is fixedly connected to the electromagnet 15. The side wall of the side rail 3 is slidably plugged with a bolt 16, and the surface of the bolt 16 is movably sleeved with a spring 2 17. One end of the bolt 16 is fixedly connected to a metal block 18, one end of the spring 2 17 is fixedly connected to the side of the side rail 3, and the other end of the spring 2 17 is fixedly connected to the metal block 18. The electromagnet 1 is started. 5 can adsorb the metal block 18, driving the latch 16 to slide in the side wall of the side rail 3, and the plug-in door 19 can slide inside the side rail 3. After the electromagnet 15 is turned off, its magnetic force disappears. At this time, the tension of the spring 17 is applied to the metal block 18, driving the latch 16 to move. When the plug-in door 19 is opened, the latch 16 engages with the second limit hole 13, fixing the position of the opened plug-in door 19. When the plug-in door 19 is closed, the latch 16 is inserted into the inside of the limit hole 12, fixing the closed plug-in door 19.

[0025] Working principle: when the device is in use, when opening and closing the plug-in door 19, the cylinder 11 is started to drive one end of the top of the scissor-type bracket 8 to move inside the slide 10, thereby driving the height of the scissor-type bracket 8 to be adjusted. At this time, one end of the bottom of the scissor-type bracket 8 will slide inside the slide 17, which can drive the height of the plug-in door 19 to be adjusted, thereby controlling the opening and closing of the plug-in door 19. The operation is simple and fast, avoiding the need for workers to manually operate it. When the plug-in door 19 is closed, the bottom end of the plug-in door 19 will fall directly onto the pad 5, and the weight of the plug-in door 19 will be applied to the spring 16, so that the plug-in door 19 is opened. The impact generated during closing is applied to spring 16 to protect the side rail 3. Starting the electromagnet 15 can adsorb the metal block 18, driving the latch 16 to slide in the side wall of the side rail 3, and the plug-in door 19 can slide inside the side rail 3. After the electromagnet 15 is turned off, its magnetic force disappears. At this time, the tension of spring 2 17 is applied to the metal block 18, driving the latch 16 to move. When the plug-in door 19 is opened, the latch 16 is engaged with the limiting hole 2 13 to fix the position of the opened plug-in door 19. When the plug-in door 19 is closed, the latch 16 is inserted into the inside of the limiting hole 12 to fix the closed plug-in door 19.
