DETAILED DESCRIPTION

[0024] Embodiment 1

[0025] like Figure 1-Figure 5 As shown, the present embodiment provides an assembled waterproof exterior wall panel, comprising an exterior wall panel body 1, a clamping assembly and a plurality of limit assembly groups.

[0026] Mounting grooves 102 are provided on both adjacent sides of the exterior wall panel body 1, and a card plate 6 is slidably installed on the inner side of the two mounting grooves 102. A sealing strip 12 is provided on the card plate 6, and the provided sealing strip 12 can prevent water from further penetrating into the plate. Card slots 101 for inserting the card plate 6 are provided on the other two sides of the exterior wall panel body 1. An elastic component is installed between the card plate 6 and the exterior wall panel body 1. The elastic component includes a guide rod 9, a spring 10 and a limit slider 11. A plurality of movable grooves 105 are provided on the exterior wall panel body 1, and the plurality of movable grooves 105 correspond to the plurality of elastic components one by one. The guide rod 9 is connected to the card plate 6, and the end of the guide rod 9 is movably arranged on the inner side of the movable groove 105 and connected to the limit slider 11, and the spring 10 is sleeved and installed on the guide rod 9; a pressure block 8 is connected to the two card plates 6, and a notch a103 for the pressure block 8 to move is provided on both adjacent sides of the exterior wall panel body 1.

[0027] A plurality of limit assemblies are installed on the back of the exterior wall panel body 1, and the exterior wall panel body 1 is clamped on the mounting cross bar 2 installed on the wall through the limit assemblies. Each set of limit assemblies includes two limit blocks 3 arranged side by side.

[0028] The clamping assembly is connected to the clamping plate 6 located at the upper end, and the exterior wall panel body 1 is limited by the clamping assembly. The clamping assembly includes a connecting frame 4, multiple connecting plates 5 and multiple limiting blocks 7. The limiting block 7 is in an "L" shape. The end of the limiting block 7 is connected to the clamping plate 6 located at the upper end. A notch b104 is provided on the side of the exterior wall panel body 1 for the end of the limiting block 7 to move. Multiple connecting plates 5 are arranged side by side on the connecting frame 4.

The limiting groove is a plurality of slots 202 equidistantly arranged on the mounting cross bar 2, and the limiting block 7 fits with the slot 202.

[0029] When installing the external wall panel body 1, the limit assembly is clamped on the corresponding installation cross bar 2, so that the two limit blocks 3 on the limit assembly are respectively placed at the upper and lower ends of the installation cross bar 2. Before this, the pressure block 8 is pressed downward to drive the connecting frame 4 to move. After the limit assembly is clamped on the installation cross bar 2, the pressure block 8 is released. At this time, the connecting frame 4 is reset under the elastic force of the spring 10, and the movement of the connecting frame 4 drives the connecting plate 5 to move, so that the limit block 7 on the connecting plate 5 is clamped into the inner side of the slot 202, thereby realizing the external wall panel. The limiting work of the main body 1 is achieved by means of two clamping plates 6 and two clamping grooves 101 arranged on the exterior wall panel main body 1, thereby preventing a large gap from appearing between two adjacent exterior wall panel main bodies 1 and preventing water leakage. When disassembling a single exterior wall panel main body 1, the two pressure blocks 8 are pressed at the same time so that the two clamping plates 6 move inward at the same time, and then the exterior wall panel main body 1 can be disassembled and removed. In summary, in the present technical solution, after multiple exterior wall panel main bodies 1 are spliced, the water-proof property is good and the disassembly structure is simple.
