Two sets of passive positioning elements 6 are provided, corresponding to the closed and open states of the sliding door 3, respectively.

[0023] When the sliding door 3 is slid to one side to completely close the opening, the active positioning element 5 and a passive positioning element 6 cooperate to position the sliding door 3, ensuring the stability of the sliding door 3 when it is closed. When the sliding door 3 needs to be opened, it is slid to the other side. When the opening is fully opened, the active positioning element 5 and another passive positioning element 6 cooperate to ensure the stability of the sliding door 3 when it is open.

[0024] The active positioning component 5 includes a first fixing plate 7 fixed to the surface of the sliding door 3. The top and bottom of the first fixing plate 7 are respectively provided with a horizontal upper support plate 8 and a lower support plate 9. The two upper support plates and the lower support plate are connected by a positioning rod 10. The top of the positioning rod 10 is bent to form a handle 11. The passive positioning component 6 includes a horizontal plate 12 horizontally set at the bottom of the box body 1. The horizontal plate 12 has a positioning groove 13 for the positioning rod 10 to be inserted.

[0025] By using the handle to slide the positioning rod 10 upwards and away from the positioning groove 13, when the sliding door 3 is pulled to the designated position, the positioning rod 10 is inserted into another positioning groove 13, thereby ensuring the stability of the sliding door 3.

[0026] The circumferential sidewall of the positioning rod 10 is provided with a lower abutment ring 14 below the upper support plate 8 and an upper abutment ring 15 above the upper support plate 8.
