Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the scope described herein.

[0023] Please refer to Figure 1-4 A seamless junction box includes a box body, which includes a base plate 1 and side plates 2 arranged around the base plate 1. The top of the box body is provided with an opening 3. The front and rear side plates 2 of the box body are respectively provided with first wiring holes 101. In this embodiment, the two side plates 2 each have three first wiring holes 101.

[0024] The bottom of the base plate 1 and the right side plate 2 extend forward to form a first splicing part, and the bottom of the base plate 1 and the left side plate 2 extend backward to form a second splicing part. The bottom surface of the first splicing part is provided with a connector 4, and the bottom surface of the second splicing part is provided with a connector groove 5, wherein the connector 4 is inserted into the connector groove 5 of the front wire box; the first splicing part fits into the second splicing part of the front wire box; the right edge of the opening 3 is symmetrically provided with cylinders 6 for splicing, and the left edge of the opening 3 is symmetrically provided with elastic round holes 7 that cooperate with the cylinders 6, wherein the cylinders 6 are engaged with the elastic round holes 7 of the front wire box.

[0025] Unlike older plug-in structures that suffer from inconvenient installation and uneven junction boxes, this new seamless junction box design allows for easy connection of two adjacent boxes. The bottom connector 4 is first snapped in, and the corresponding cylinder 6 at the opening is then engaged through the elastic deformation of the round hole. Installation is smooth, disassembly is convenient, and even when multiple junction boxes are joined, a flush connection is ensured.

[0026] The inner wall of opening 3 has a ring edge 8 along its circumferential direction, which makes the entire outer frame sink. After the junction box is installed on the wall, the sinking outer frame can be covered with cement during plastering to ensure that it is not exposed, while the junction box can be flush with the wall surface.

[0027] The annular edge 8 and the opening 3 are respectively and symmetrically provided with mounting grooves 9 on the left and right sides.

[0028] Please refer to Figure 5 In this embodiment, the junction box also includes a protective cover 10. The protective cover 10 has symmetrical connecting shafts 11 on the front and rear sides that match the size of the mounting groove 9. The protective cover 10 has a limiting block 12 on the right side, which is also the point of force for opening and closing the cover. The protective cover 10 can be inserted into the mounting groove 9 regardless of direction, so as to flip to the left or right.

[0029] Please refer to Figure 6 The two side plates 2 are symmetrically provided with square protrusions 18 on their inner sides. The opening edge of the square protrusion 18 is a first-level step 13 for protecting the wire post, which isolates the pointed screw from the wire. The square protrusion 18 is provided with a second-level step 14 for spare screw holes, so that it can still be installed normally after the original screw hole position is damaged.

[0030] The base plate 1 has a mounting hole 15 for the tool air gun at its center. In this embodiment, the mounting hole 15 is a circular protrusion.

[0031] The left and right side plates 2 are respectively and symmetrically provided with mounting rings 16. A cover 17 is installed inside the mounting ring 16. A destructible support foot is fixed between the outer periphery of the cover 17 and the inner periphery of the corresponding mounting ring 16.
