A dome-shaped connecting plate 11 is fixedly installed at the end face of the fixed rod 10. An insertion groove 12 is opened on the back of the wall 1 corresponding to the dome-shaped connecting plate 11. A fixing mechanism 13 is fixedly installed on the inner wall of the insertion groove 12. The left door 3 and the right door 4 push the dome-shaped connecting plate 11 on the fixed rod 10 into the fixing mechanism 13, and an ejecting mechanism 21 is arranged inside the fixing mechanism 13.

[0025] As Figure 4-5 As shown, the fixing mechanism 13 includes a main board 14. A moving groove 15 is opened inside the main board 14. A guide rod 16 is fixedly installed on the inner wall of the moving groove 15. Two moving plates 17 corresponding to the guide rod 16 are arranged inside the moving groove 15. Arc-shaped plates 18 corresponding to the dome-shaped connecting plate 11 are fixedly installed at the ends of the two moving plates 17 close to each other. The dome-shaped connecting plate 11 pushes the arc-shaped plate 18 to move along the moving groove 15. When the dome-shaped connecting plate 11 completely passes through the arc-shaped plate 18, the moving plate 17 pushes the arc-shaped plate 18 to abut against the fixed rod 10, so that the dome-shaped connecting plate 11 is fixed in the moving groove 15. A sliding groove 19 is opened at the bottom of the inner wall of the moving groove 15. Moving rods 20 are fixedly installed at the bottom surfaces of the two moving plates 17 corresponding to the sliding groove 19. Guide rods are fixedly installed on both sides of the inner wall of the sliding groove 19 corresponding to the moving rods 20. A third spring is sleeved on the outer surface of the guide rod. Two ends of the third spring are respectively fixedly connected to the inner wall of the sliding groove 19 and the side surface of the moving rod 20. The third spring always pushes the two moving rods 20 to approach each other, further making the inner wall of the arc-shaped plate 18 more tightly attached to the outer surface of the fixed rod 10. An ejecting mechanism 21 is fixedly installed on the inner wall of the sliding groove 19 corresponding to the moving rod 20, and the ejecting mechanism 21 realizes the unlocking of the fixing mechanism 13.

[0026] As Figure 6-7As shown, the ejection mechanism 21 includes a main body 22, a sliding groove 23 is provided inside the main body 22, a sliding rod 24 is provided inside the sliding groove 23, a top plate 25 is fixedly installed on the end of the sliding rod 24 close to the moving rod 20, a plurality of rounded corners are provided on the top plate 25 close to the sliding rod 24, an extrusion plate 26 is fixedly installed on the end of the sliding rod 24 away from the top plate 25, a circular groove 27 is provided on the inner wall of the sliding groove 23, a circular plate 28 is provided inside the circular groove 27, the circular plate 28 is fixedly connected to the sliding rod 24, the top plate 25 pushes the moving plate 17 to move along the sliding groove 19, when reaching the maximum position, the dome-shaped connecting plate 11 leaves the fixing mechanism 13, when the top plate 25 contracts, the moving rod 20 leaves the top plate 25 along with the rounded corners on the top plate 25.

[0027] like Figure 7-8 As shown, a dome 29 is provided on one side of the top plate 25 close to the moving rod 20 , and the dome 29 enables the top plate 25 to enter the moving rod 20 more easily, while reducing the probability of damage to the moving rod 20 .

[0028] like Figure 8 As shown, a slope 30 corresponding to the top plate 25 is provided on one side of the two moving rods 20 that are close to each other. The slope 30 corresponds to the dome 29 , so that the top plate 25 can enter between the two moving rods 20 more easily.

[0029] like Figure 5 As shown, a first spring 31 is sleeved on the outer surface of the guide rod 16, and the two ends of the first spring 31 are fixedly connected to the inner wall of the movable groove 15 and the side of the movable plate 17 respectively. When the dome-shaped connecting plate 11 enters the fixing mechanism 13, the first spring 31 pushes the arc plate 18 on the movable plate 17 to always abut against the dome-shaped connecting plate 11, so as to quickly fix the dome-shaped connecting plate 11.

The dome-shaped connecting plate 11 pushes the moving plate 17 on the arc plate 18 to move along the moving slot 15. At the same time, the first spring 31 pushes the arc plate 18 on the moving plate 17 along the axial direction of the guide rod 16 to be in close contact with the dome-shaped connecting plate 11. The third spring pushes the two moving rods 20 to approach each other along the axial direction of the guide rod. When the dome-shaped connecting plate 11 completely passes through the arc plate 18, the moving plate 17 and the moving rod 20 are simultaneously pushed by the first spring 31 and the third spring, so that the arc plate 18 on the moving plate 17 abuts against the fixed rod 10, and the dome-shaped connecting plate 11 is fixed in the moving slot 15. When it is necessary to close, the user pushes the extrusion plate 26, the extrusion plate 26 pushes the top plate 25 on the sliding rod 24, and the top plate 25 pushes the two moving rods 20 to separate. After the dome-shaped connecting plate 11 leaves the fixing mechanism 13, the second spring 32 pushes the sliding rod 24 on the round plate 28 to move, and the sliding rod 24 drives the top plate 25 to push the two moving plates 17 to separate, so that the top plate 25 returns to the origin.
