A rotating member 22 is fixedly mounted on the surface of the rotating rod 21 , and a positioning groove 23 is formed on the rear side of the rotating member 22 .

[0026] The docking assembly 3 includes a moving plate 31 and a guide rod 34 . A docking post 32 is fixedly mounted on the front side of the moving plate 31 , and the docking post 32 matches the positioning groove 23 .

[0027] Furthermore, a limit plate 25 is provided on the rear side of the rotating member 22, and the limit plate 25 is fixedly connected to the wall of the built-in groove 11. A toggle ring 24 is fixedly installed on the front side of the rotating member 22, and a guide arc surface 221 is also provided on the rear side of the rotating member 22. The guide arc surface 221 is used to guide the docking column 32 into the positioning groove 23. A coil spring 26 is sleeved on the surface of the rotating rod 21, and two coil springs 26 are symmetrically provided on each rotating rod 21. One end of the coil spring 26 is fixedly connected to the surface of the rotating rod 21, and the other end of the coil spring 26 is fixedly connected to the wall of the built-in groove 11. The elastic force of the coil spring 26 can drive the rotating member 22 to rotate around the axis of the rotating rod 21 in the direction close to the limit plate 25. The staff can pull the toggle ring 24 by hand to rotate the rotating member 22 around the axis of the rotating rod 21 in the direction away from the limit plate 25, thereby separating the docking column 32 from the positioning groove 23.

[0028] Furthermore, guide blocks 33 are fixedly installed on the top and bottom of the moving plate 31, and each docking assembly 3 includes two guide rods 34, both ends of the guide rods 34 are fixedly connected to the walls of the built-in groove 11, and the guide blocks 33 are sleeved on the surface of the guide rods 34. The guide blocks 33 and the guide rods 34 form a sliding guide cooperation along the axial direction of the guide rods 34. A toggle block 35 is fixedly installed on the front side of the moving plate 31, and a compression spring 36 is sleeved on the surface of the guide rod 34. One end of the compression spring 36 is fixedly connected to one side of the guide block 33, and the other end of the compression spring 36 is fixedly connected to the wall of the built-in groove 11. The elastic force of the compression spring 36 can drive the moving plate 31 and the docking column 32 to retract into the built-in groove 11. The staff can push the moving plate 31 out of the built-in groove 11 by pushing the toggle block 35, which is simple and convenient to operate.

[0029] Furthermore, a through hole 12 with a strip-shaped hole structure is provided through the wall of the built-in groove 11, a fixing ring 13 is fixedly installed at the notch of the built-in groove 11, and an insertion groove 14 is provided at the four corners of the fixing ring 13, and an insertion column 41 is fixedly installed at the four corners of the closing cover 4, the insertion column 41 matches the insertion groove 14, and a magnet is provided between the insertion column 41 and the insertion groove 14, and a detent groove 42 is also provided on the closing cover 4, and the insertion column 41 can be fixed in the insertion groove 14 under the adsorption action of the magnet, so that the closing cover 4 is fixed at the notch of the built-in groove 11, and the closing cover 4 blocks the built-in groove 11 to ensure the beauty of the overall structure.

[0030] The working principle of the present utility model is as follows: during actual operation, the staff removes the closing cover 4 from the notch of the built-in groove 11, pushes the toggle block 35 by hand, causes the guide block 33 on the docking column 32 to slide along the guide rod 34, and the compression spring 36 is stretched under the pull of the guide block 33. The elastic force of the compression spring 36 increases, and the moving plate 31 and the docking column 32 pass through the through hole 12 and extend outward from the built-in groove 11. The staff inserts the moving plate 31 and the docking column 32 into the built-in groove 11 of the other sandwich panel body 1, and the docking column 32 First, it contacts the guiding arc surface 221. Under the push of the docking post 32, the rotating member 22 rotates around the axis of the rotating rod 21 in the direction away from the limit plate 25. At the same time, the coil spring 26 is wound and the elastic force increases. When the docking post 32 is separated from the guiding arc surface 221, the elastic force of the coil spring 26 drives the rotating member 22 to rotate around the axis of the rotating rod 21 in the direction close to the limit plate 25. The docking post 32 enters the positioning groove 23. The docking post 32 and the positioning groove 23 cooperate with each other to fix the two adjacent sandwich panel bodies 1.

[0031] When the fixation needs to be released, the staff pulls the toggle ring 24 by hand to rotate the rotating part 22 around the axis of the rotating rod 21 in the direction away from the limit plate 25. At this time, the docking column 32 is separated from the positioning groove 23, and the elastic force of the compression spring 36 drives the moving plate 31 and the docking column 32 to retract into the built-in groove 11, and the separation between the two sandwich panel bodies 1 is completed.
