[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0020] Specific embodiment 1: Please refer to Figures 1 to 7 In an embodiment of the utility model, a bottom box of a switch panel comprises a middle frame plate 1 and a bottom shell 2, wherein the bottom shell 2 is provided with a receiving cavity 201, the bottom shell 2 is snap-connected to the rear side of the middle frame plate 1, and the bottom shell 2 is provided with at least two first hooks 202 extending toward the middle frame plate 1. In the present application, the bottom shell 2 is a rectangular structure, and chamfers are respectively provided at the four end corners of the bottom shell 2, and four first hooks 202 are provided on the bottom shell 2, and the first hooks 202 are respectively located at the four end corners, and a concave first placement groove 101 is provided on the front side of the middle frame plate 1, and a first mounting hole 102 is provided in the first placement groove 101 and snap-connected with the first hook 202, and a concave second placement groove 105 is provided on the rear side of the middle frame plate 1, and a PCB board 3 is installed in the second placement groove 105, and the PCB board 3 is snap-installed with the middle frame plate 1, and the PCB board 3 is in the receiving cavity 201 of the bottom shell 2.
[0021] At least two second hooks 106 are provided in the second placement slot 105. In the present application, a second hook 106 is provided on the upper left and right sides of the second placement slot 105, and a second hook 106 is provided at the lower position of the second placement slot 105. The positions of the three second hooks 106 form a triangular installation position. The PCB board 3 is provided with a corresponding second installation hole 301 that is snap-connected with the second hook 106. A plurality of raised positioning blocks 107 are provided in the second placement slot 105. The PCB board 3 is provided with a corresponding positioning through hole 302 that is plugged with the positioning block 107. In the present application, a positioning block 107 is provided on the upper left and right sides of the second placement slot 105, and a positioning block 107 is provided at the lower position of the second placement slot 105. The positions of the three positioning blocks 107 form a triangular installation position. Through the cooperation of the positioning blocks 107, the PCB board 3 can be quickly positioned and snapped on the middle frame board 1.
[0022] The first placement groove 101 is symmetrically provided with connecting holes 103 on the left and right sides, and an adjustment hole 104 is provided on one side of the connecting hole 103. The connecting holes 103 and the adjustment holes 104 both pass through the front and rear ends of the middle frame plate 1. The adjustment hole 104 is a rectangular long hole structure. The connecting hole 103 is used for threaded connection between the middle frame plate 1 and the panel. The setting of the adjustment hole 104 can effectively solve the problem that when the panel and the middle frame plate 1 are threadedly installed, the locking screws easily cause the middle frame plate 1 to be greatly deformed, resulting in a large gap between the middle frame plate 1 and the wall, thereby ensuring a tight connection between the middle frame plate 1 and the wall.
[0023] The top of the accommodating cavity 201 is a wiring area, on which a number of wiring holes 203 are arranged side by side in the horizontal direction, and a partition 204 is provided between each wiring hole 203.
