Problems solved by technology

[0005] Beneficial effects of the present invention: Since the present invention adopts a self-locking closing structure on the sliding door, people only need to press a button when closing the sliding door, and the button drives the rotating pulley and the large cam through the elastic spring, and the large cam passes through the rotating pulley The pressing and pulling rotation force of the elastic spring can drive the lock tongue to realize the purpose of opening and closing the sliding door. Therefore, the present invention has the advantages of simple structure, convenient operation, good use effect, automatic closing, and convenient opening and pushing, and effectively overcomes the existing problems. There are defects in sliding door pins that are difficult to push and insert due to misalignment or use for a period of time due to the sinking of the door
