Two sliding blocks 27 are slidably arranged in the sliding bin 10, and the two sliding blocks 27 are respectively located on the two sides of the protrusion 31. One side of each of the two sliding blocks 27 is fixedly connected with the other end of each of the two adjacent guide rods 28. A second spring 29 is sleeved on each of the guide rods 28, and the two ends of each of the second springs 29 are fixedly connected with one side of the corresponding fixed plate 30 and one side of the corresponding sliding block 27. Through the design of the abutting plate 11, the guide rod 28, the second spring 29 and the sliding block 27, the door can be quickly reset when needed, greatly improving the operation convenience and efficiency.

[0040] One side of each of the two sliding blocks 27 is penetratingly provided with a groove 32, and the two grooves 32 are respectively matched with the two ends of the protrusion 31. By rotating the control handle 4, the protrusion 31 is rotated by 90 degrees, and the two ends of the protrusion 31 are clamped into the corresponding grooves 32, so that the sliding door 3 is locked at any position.

[0041] One side of the flat groove 21 is fixedly provided with a magnetic block 22, and the magnetic block 22 is magnetically attracted to the ball at one end of the limiting pin 17.

[0042] The bottom end of the movable door 3 is provided with a plurality of rollers 8, and the plurality of rollers 8 are all rolled on one side of the corresponding slide rail 2. When the door needs to be moved, the plurality of rollers 8 ensure the smooth movement of the movable door 3.

[0043] The upper end of the movable door 3 is provided with a plurality of damping shafts 24, and the plurality of damping shafts 24 are all in sliding connection with the movable door 3. A plurality of anti-dropping blocks 25 are fixedly sleeved on the plurality of damping shafts 24, and one end of each of the plurality of anti-dropping blocks 25 is rotatably provided with a rubber roller. One side of the slide rail 2 located on the top wall of the door frame 1 is provided with an anti-dropping groove 33, and the rubber roller at one end of the anti-dropping block 25 is rolled in the anti-dropping groove 33 and is matched with the anti-dropping groove 33. Through the design of the damping shaft 24, the anti-dropping block 25 and the anti-dropping groove 33, the door will not be separated from the slide rail 2 during movement, thereby improving the stability and safety of use.

[0044] One end of the plurality of damping shafts 24 penetrates the movable door 3 and extends to the outside, and one end of the damping shaft 24 is fixedly sleeved with an adjusting head 26. Through the design of the damping shaft 24 and the adjusting head 26, the user can adjust the position of the door according to his own needs, thereby increasing the use flexibility.

[0045] Working principle: in use, the convex block 31 is rotated by 90 degrees through the rotating control handle 4, and the two ends of the convex block 31 are clamped into the corresponding grooves 32, at the same time, the rotating action drives the two abutting plates 11 to move, and the two ends of the abutting plate 11 abut against the two slide rails 2, so that the movable door 3 is locked at any position. Through the cooperation of the two fixed plates 30, the plurality of guide rods 28 and the second spring 29 in the sliding bin 10 and the sliding block 27, when it is necessary to release, it is ensured that the abutting plate 11 can be quickly reset and released, thereby improving the convenience of operation. When the movable door 3 is completely closed, it is only necessary to slide the movable door 3 into the rectangular notch 5, so that the barb 15 is clamped at one end of the clamping plate 7. In order to prevent accidental operation, when it is necessary to reopen, it is necessary to continue to push the movable door 3 in the direction of the rectangular notch 5 with force. At this time, the limiting pin 17 will be sequentially moved into the first inclined groove 19, the second inclined groove 20 and the flat groove 21. When the limiting pin 17 moves to the first inclined groove 19, the sliding plate 12 will be extruded to move horizontally and separate the barb 15 from the clamping plate 7. When the limiting pin 17 moves to the position of the second inclined groove 20, the ball at one end of the limiting pin 17 will be attracted to the magnetic block 22 and make the limiting pin 17 smoothly slide into the flat groove 21. At this time, under the action of the elastic force of the spring pin 23 in the opposite direction, the movable door 3 is popped out to complete the opening action. In actual use, it is very convenient to push the door, without repeating the previous locking action.
