[0040] Please refer to Figures 1 to 7 This application proposes a connection device for prefabricated walls, including two prefabricated walls 100 and a connection device 200. A connection groove 111 and a snap-fit ​​groove 112 are provided between each of the two prefabricated walls 100. The connection groove 111 and the snap-fit ​​groove 112 are connected, and the snap-fit ​​groove 112 is located below the connection groove 111. The connection device 200 is disposed between the two prefabricated walls 100. Both sides of the connection device 200 include a connection portion 221 and a snap-fit ​​portion 222. The connection portion 221 is fixedly connected to the snap-fit ​​portion 222. The height of the snap-fit ​​portion 222 is less than or equal to the height of the connection groove 111. The snap-fit ​​portion 222 is snapped downwards into the snap-fit ​​groove 112 via the connection groove 111, while the connection portion 221 extends into the connection groove 111 to connect the two prefabricated walls 100.

[0041] Specifically, each wall panel is provided with a connecting groove 111 and a snap-fit ​​groove 112. The connecting groove 111 and the snap-fit ​​groove 112 are connected, and the snap-fit ​​groove 112 is located below the connecting groove 111. The connecting device 200 is located between the two prefabricated wall panels 100. The connecting device 200 has a connecting part 221 and a snap-fit ​​part 222 on both sides, and the connecting part 221 and the snap-fit ​​part 222 are fixedly connected. The height of the snap-fit ​​part 222 is less than or equal to the height of the connecting groove 111. During installation, the snap-fit ​​part 222 snaps downward into the snap-fit ​​groove 112 through the connecting groove 111, while the connecting part 221 extends into the connecting groove 111 to achieve a stable connection between the two walls. This design utilizes the precise fit between the snap-fit ​​groove 112 and the connecting groove 111, enabling the two walls to be stably connected together by snapping, avoiding the instability that may be caused by dimensional errors in traditional plug-in structures, thereby ensuring the accuracy of the connection and the stability of the overall wall structure. This effectively reduces connection inaccuracies caused by construction errors, improving the connection accuracy and stability of the prefabricated wall 100. During construction, workers only need to insert the snap-fit ​​part 222 of the connecting device 200 into the connecting groove 111 and press it down to fix it, avoiding the cumbersome debugging and alignment process in traditional connection methods, greatly simplifying construction operations, improving construction efficiency, and significantly enhancing the construction accuracy, stability, and efficiency of the prefabricated wall 100.

[0042] Please refer to Figure 2 and Figure 5 In one embodiment, a protrusion 110 is provided between the two prefabricated wall panels 100 along the vertical direction.

[0043] Specifically, each of the two prefabricated wall panels 100 has a protrusion 110 along the vertical direction. The protrusion 110 allows the connecting groove 111 and the snap-fit ​​groove 112 to be more accurately positioned on the wall. Specifically, the connecting groove 111 and the snap-fit ​​groove 112 are both located on the side of the protrusion 110 facing the connecting device 200, while the connecting device 200 itself has a groove 250 along the vertical direction, and the protrusion 110 is snapped into this groove 250. This design allows the connecting device 200 to connect more stably to the wall during installation, avoiding misalignment problems caused by uneven wall gaps or inaccurate installation, and further enhancing the connection accuracy of the prefabricated wall panel 100.

[0044] Please refer to Figures 5 to 7In one embodiment, the connecting device 200 includes a fixing mechanism (not shown in the figure) on both sides. The fixing mechanism includes a driving member 210 and a lifting rod 220. The connecting part 221 and the snap-fit ​​part 222 are provided on the lifting rod 220.

The lead screw 213 is threadedly connected to the lifting rod 220, and both ends of the lead screw 213 are rotatably connected to the positioning housing 230. The driving wheel 211 can drive the lead screw 213 to rotate, so as to move the lifting rod 220 up or down.

[0047] Specifically, the drive component 210 consists of a drive wheel 211, a driven wheel 212, and a lead screw 213. The drive wheel 211 is rotatably connected to the positioning housing 230, the driven wheel 212 meshes with the drive wheel 211, and the lead screw 213 is connected to the driven wheel 212, and the lead screw 213 and the driven wheel 212 are coaxial. Both ends of the lead screw 213 are rotatably connected to the positioning housing 230 and are connected to the lifting rod 220 via threads. When the drive wheel 211 rotates, the drive component 210 drives the lifting rod 220 to move vertically through the lead screw 213, thereby adjusting the position of the connecting part 221 and the locking part 222. This design, through the precision lead screw 213 transmission system, enables precise control of the lifting rod 220, ensuring smoother and more accurate height adjustment of the connecting part 221 and the locking part 222, thereby enhancing the operational accuracy and stability of the connecting device 200.

[0048] Please refer to Figure 2 and Figure 6In one embodiment, the connecting device 200 further includes two connecting plates 240, both of which are attached to and perpendicular to the two positioning shells 230, and the two connecting plates 240 and any one of the positioning shells 230 form a groove 250 facing the prefabricated wall 100.

[0049] Specifically, the connecting device 200 also includes two connecting plates 240, which are respectively attached to and perpendicular to a positioning shell 230.
