It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4As shown, this utility model provides an AC low-voltage distribution box, including a distribution box body 1. The distribution box body 1 includes a box body 11, a box door 12, a heat dissipation baffle 13, and a support plate 14. Two support plates 14 are provided, and the two support plates 14 are fixedly connected to the inner wall of the box body 11. A mounting bracket assembly 2 is installed between the two support plates 14. The mounting bracket assembly 2 includes a mounting plate 21, a connecting hole 22, a fixing plate 23, a connecting clip 24, a connecting support plate 25, an outer plate 26, an elastic clamping plate 27, and a guide wheel 28. The fixing plate 23 is fixedly connected to the mounting plate 21. At one end, the connecting block 24 is fixedly connected to the outer wall of the fixed plate 23, the connecting support plate 25 is fixedly connected to the outer wall of the support plate 14, the outer sleeve plate 26 is fixedly connected to the outer wall of the connecting support plate 25, one end of the elastic clamping plate 27 is installed on the inner wall of the outer sleeve plate 26, the connecting block 24 is snapped into the inner wall of the elastic clamping plate 27, the outer wall of the connecting block 24 is provided with a positioning insertion hole 241, the inner wall of the positioning insertion hole 241 is inserted into a limiting rod 29, one end of the limiting rod 29 is fixedly connected to the outer wall of the outer sleeve plate 26, and the guide wheel 28 is rotatably connected to one end of the elastic clamping plate 27.

[0024] The specific settings and functions of this embodiment are described below. By removing the mounting plate 21 from the main body 1 of the distribution box, the required components are pre-installed on the mounting plate 21. The connecting support plate 25 is installed on the support plate 14 to fix the elastic clamp 27. Then, the connecting blocks 24 at both ends of the mounting plate 21 are inserted into the elastic clamp 27 through the guide wheels 28. The mounting plate 21 is further fixed by the insertion limit of the limiting rod 29 and the positioning hole 241, which prevents shaking during subsequent use. This achieves quick snap-fit ​​fixing of the mounting plate 21 and the elastic clamp 27, making it easy for installers to quickly fix the components inside the main body 1 of the distribution box, effectively improving the installation efficiency of this utility model. In subsequent maintenance and inspection, the mounting plate 21 and the components mounted on its surface can be quickly disassembled by the snap-fit ​​of the connecting blocks 24 and the elastic clamp 27, which is convenient for maintenance and inspection.

[0025] Example 2: Figure 1 - Figure 4 As shown, the heat dissipation baffle 13 is fixedly connected to the outer wall of the box 11, one side of the box door 12 is rotatably connected to the outer wall of the box 11, an alarm light 3 is installed on the top surface of the box 11, a smoke sensor 4 is installed on the inner wall of the outer cover plate 26, one end of the smoke sensor 4 is connected through to the back of the outer cover plate 26, the smoke sensor 4 is electrically connected to the alarm light 3, and the outer wall of the connection hole 22 is opened through to the outer wall of the mounting plate 21.

[0026] The overall effect of this embodiment is that by using the smoke sensor 4 inside the outer casing 26 to detect smoke inside the housing 11, when the internal electrical components of this utility model malfunction, such as short circuits or overloads, electric sparks or local overheating may be generated. Overheating may cause the surrounding insulation materials, wire sheaths, etc. to burn and generate smoke. The smoke sensor 4 can sensitively detect this smoke, so that an alarm signal is sent to the alarm light 3 in the early stage of a fire. The alarm light 3 will then light up to sound an alarm. The connection hole 22 makes it easy to pre-install the required components on the mounting plate 21.

[0027] The usage and working principle of this device are as follows: During installation, the user removes the mounting plate 21 from the main body 1 of the distribution box, pre-installs the required components on the mounting plate 21 through the connection holes 22, and installs the connecting support plate 25 on the support plate 14 to fix the elastic clamping plate 27. Then, the connecting clips 24 at both ends of the mounting plate 21 are inserted into the elastic clamping plate 27 through the guide wheels 28, realizing the quick snap-fit ​​fixing of the mounting plate 21 and the elastic clamping plate 27. This facilitates the installer to quickly fix the components inside the main body 1 of the distribution box, and allows for quick and easy maintenance during subsequent inspections. Quickly remove the mounting plate 21 along with the components mounted on its surface. Use the smoke sensor 4 inside the outer cover plate 26 to detect smoke inside the housing 11. This allows the present invention to detect smoke when internal electrical components malfunction, such as short circuits or overloads, which may generate electrical sparks or local overheating. Overheating may cause surrounding insulation materials, wire sheaths, etc. to burn, producing smoke. The smoke sensor 4 can sensitively detect this smoke, so that an alarm signal is sent to the alarm light 3 in the early stage of a fire, and the alarm light 3 will light up to sound an alarm.
