[0053] Embodiment three:

[0054] like Figures 1 to 8 As shown, in this embodiment, a panel wiring bottom box is shown, including a bottom plate 12 and a side plate 11 arranged around the bottom plate 12, the side plate 11 includes a first side plate 111, a second side plate 112, a third side plate 113 and a fourth side plate 114, wherein the first side plate 111 and the second side plate 112 are arranged opposite to each other, and the third side plate 113 and the fourth side plate 114 are arranged opposite to each other, and the outer sides of the first side plate 111 and the second side plate 112 are both provided with a clamping plate 22, a connecting buckle 21, a guide cylinder 24 and a guide rib 23, the guide rib 23 of the first side plate 111 and the guide cylinder 24 of the second side plate 112 are arranged opposite to each other, and the first side plate 111 and the second side plate 112 are arranged opposite to each other. The guide cylinder 24 of the side panel 111 is arranged opposite to the guide rib 23 of the second side panel 112, the clamping plate 22 of the first side panel 111 is arranged opposite to the connecting buckle 21 of the second side panel 112, and the connecting buckle 21 of the first side panel 111 is arranged opposite to the clamping plate 22 of the second side panel 112. During the connection process, the guide rib 23 is inserted into the guide cylinder 24, and the clamping plate 22 is clamped with the connecting buckle 21, which is beneficial to improve the connection stability of the two box bodies 1. After being installed in the wall, the possibility of misalignment between the two box bodies 1 can be reduced, making the installation of the panel more accurate, which is beneficial to improving the aesthetics of the panel.

[0055] like Figure 2 and Figure 7 As shown, the snap-in plate 22 in this embodiment is concave inwardly along a direction perpendicular to the bottom plate 12 to form a snap-in groove 221, and the connecting buckle 21 is convex in a direction perpendicular to the bottom plate 12 to form a snap-in block, that is, the snap-in plate 22 and the connecting buckle 21 are plugged in or separated in a direction perpendicular to the bottom plate 12; when two adjacent box bodies 1 are close to each other and are clamped together by the snap-in structure, the snap-in structure can limit the two box bodies 1 from being separated from each other in the direction of the bottom plate, and at the same time, the two box bodies can rotate relative to each other with the snap-in point between the snap-in plate 22 and the connecting buckle 21 as the rotation axis, so that the guide cylinder 24 and the guide rib 23 are close to each other and the plug-in is completed.

[0056] After two adjacent box bodies 1 are connected, the first side plate 111 of one box body 1 abuts against the second side plate 112 of the other box body 1, and the bottom plates 12 of the two box bodies 1 abut against each other. When the two box bodies 1 need to be separated, the abutting point of the two bottom plates 12 is used as the rotation axis to control the two box bodies 1 to rotate relative to each other, so that the top ends of the two abutting side plates 11 gradually separate. In this embodiment The guide cylinder 24 and the guide rib 23 are close to the top of the side plate 11, and the clamping plate 22 and the connecting buckle 21 are close to the bottom plate 12. Therefore, during the rotation process, the clamping plate 22 and the connecting buckle 21 remain plugged, and the guide cylinder 24 and the guide rib 23 are gradually separated. After the guide rib 23 is separated from the guide cylinder 24, the two box bodies 1 can be separated and combined. Figure 7 During the separation process, an upward force is applied to the abutment of the two bottom plates 12, and at the same time, the two box bodies 1 are controlled to rotate relative to each other, so that the top ends of the two abutting side plates 11 are gradually separated. When the guide column 23 and the guide cylinder 25 are separated, the two box bodies 1 are controlled to move relative to each other along the first separation direction 71, so that the clamping plate 22 is separated from the connecting buckle 21, and the separation of the two box bodies 1 can be achieved. In this embodiment, the separation process of the box body 1 is relatively simple and labor-saving, and at the same time, it will not cause damage to the clamping plate 22 and the connecting buckle 21, effectively reducing the possibility of breakage of the clamping plate 22 and the connecting buckle 21.

[0057] Of course, it is understandable that in other embodiments, the snap-in plate 22 and / or the connecting buckle 21 may have a certain elasticity so that the snap-in structure of the two box bodies 1 can withstand a certain deformation when snapping and separating, so that the snap-in or separation direction of the two box bodies 1 in the snap-in structure is no longer limited to the first separation direction 71, and may be oblique or even in a direction perpendicular to the first separation direction 71, making the operation of separating the two box bodies 1 faster and more convenient.

[0058] In addition, in order to reduce the difficulty of plugging and separating the guide rib 23 and the guide tube 24, the end of the guide rib 23 in this embodiment is provided with a guide bevel. Of course, it can be understood that in other embodiments, the guide bevel can also be set at the opening of the guide tube 24, or the end of the guide rib 23 and the opening of the guide tube 24 can both be provided with a guide bevel.

[0059] like Figure 7 As shown, when at least two box bodies 1 need to be installed in a wall, the two box bodies 1 are first connected by the clamping plate 22 and the connecting buckle 21 .

[0060] During the installation process, a downward force is applied to the top ends of the two abutting side panels 11 to push the box body 1 into the wall. During the pushing process, the two box bodies 1 tend to separate from each other at the bottom plate 12. Since the clamping plate 22 and the connecting buckle 21 are close to the bottom plate 12, the separation of the two bottom plates 12 can be effectively restricted, so that the two box bodies 1 maintain a stable connection, which can reduce the possibility of misalignment between the two box bodies 1, make the installation of the panel more accurate, and help improve the aesthetics of the panel.

[0061] In order to reduce the difficulty of separating the box body 1, in this embodiment, the clamping plate 22 and the connecting buckle 21 are located at the edge of the side plate 11 close to the bottom plate 12, and the guide cylinder 24 and the guide rib 23 are located at the upper end of the side plate 11 away from the bottom plate 12, which can effectively increase the distance between the guide cylinder 24 and the guide rib 23 and the clamping plate 22 and the connecting buckle 21. During the separation process, the two box bodies 1 can rotate relatively at a small angle to make the guide rib 23 detach from the guide cylinder 24, further reducing the difficulty of separating the box body 1. At the same time, it can also avoid the jamming of the guide cylinder 24 and the guide rib 23, so that the box body 1 can be stably separated.

[0062] like Figure 3 As shown, in this embodiment, two wire outlet holes 15 are provided on the first side panel 111 and the second side panel 112, and the first side panel 111 and the second side panel 112 are provided with a first shear wall 171. The first shear wall 171 is located on the upper side of the wire outlet hole 15, and the lower end of the first shear wall 171 is connected to the wire outlet hole 15. The upper end of the first shear wall 171 extends to the top of the side panel 11, and the first shear wall 171 is between the guide cylinder 24 and the guide rib 23. Taking the first side panel 111 as an example, when the first shear wall 171 on the first side panel 111 is sheared off, the first side panel 111 where the guide cylinder 24 is located is still connected to the fourth side panel 114, and similarly, the first side panel 111 where the guide rib 23 is located is also connected to the third side panel 113, so that the side panel 11 where the guide rib 23 and the guide cylinder 24 are located maintains sufficient strength, thereby reducing the possibility of the guide rib 23 and the guide cylinder 24 being offset.

[0063] It should be noted that, in other embodiments, the first side plate 111 may only be provided with guide ribs 23 and clamping plates 22, and the corresponding second side plate 112 may only be provided with guide cylinders 24 and connecting buckles 21; of course, the first side plate 111 may also only be provided with guide ribs 23 and connecting buckles 21, and the second side plate 112 may also only be provided with guide cylinders 24 and clamping plates 22.

[0064] It should be noted that in other embodiments, the third side panel 113 and the fourth side panel 114 may also be provided with a snap-in plate 22, a connecting buckle 21, a guide cylinder 24 and a guide rib 23, so as to make the connection between the box bodies 1 more convenient, so as to realize splicing of different shapes, which is beneficial to increase the arrangement style of the panel and reduce the design difficulty.

[0065] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
