The connecting assembly is arranged between the fixing plate 1 and the mounting keel 2 and is detachably connected with the fixing plate 1 and the mounting keel 2, respectively. The connecting assembly is arranged to connect the fixing plate 1 and the mounting keel 2 and connect the monitor main body 4 and the fixing plate 1, so as to stably fix the monitor main body 4 on the mounting keel 2 in the low-voltage switch cabinet. It should be noted that the electrical fire monitor is a residual current electrical fire monitor.

[0035] Specifically, the connecting assembly is provided in two groups, and the two groups of connecting assemblies are arranged in parallel from top to bottom on the fixed plate 1. Any one group of connecting assemblies comprises a bearing plate 31, an L-shaped plate 32, a connecting part 33 and a fixed plug block 34. The bearing plate 31 is detachably fixed on the fixed plate 1. Specifically, the fixed plug block 34 is fixed in a rectangular array on the fixed plate 1, and the extension direction of the fixed plug block 34 is downward or upward. The bearing plate 31 is provided with a plug-in groove 313 matched with the fixed plug block 34. By inserting the fixed plug block 34 into the plug-in groove 313, the detachable connection of the bearing plate 31 and the fixed plate 1 is realized. Further, the bearing plate 31 is provided with a sliding groove 311 and a clamping groove 312, and two L-shaped plates 32 are symmetrically arranged in the sliding groove 311. In order to fix the L-shaped plate 32 in the clamping groove 312, the L-shaped plate 32 is provided with an elastic clamping block 321 matched with the clamping groove 312, and the elastic clamping block 321 is made of elastic material. By clamping the elastic clamping block 321 in the clamping groove 312, the connection of the L-shaped plate 32 and the bearing plate 31 is realized. Further, in order to facilitate the disassembly of the L-shaped plate 32, the connecting assembly further comprises a pull rod 35, which is in the shape of a C-shaped frame. The two ends of the pull rod 35 are slidably arranged in the L-shaped plate 32 and are connected to the elastic clamping block 321 respectively. When it is necessary to disassemble the L-shaped plate 32, only the pull rod 35 needs to be pulled to move the elastic clamping block 321 towards the direction of the pull rod 35, so that the elastic clamping block 321 can be pulled out of the clamping groove 312. By pulling the pull rod 35, the L-shaped plate 32 can be moved along the direction of the sliding groove 311.

[0036] The connecting part 33 is arranged on the L-shaped plate 32 and detachably connected with the mounting keel 2.

Specifically, the mounting keel 2 is fixed with a mounting plate 21, the mounting plate 21 is provided with a mounting through hole, the elastic rod 332 passes through the mounting through hole and extends towards the mounting keel 2, and the fixing ring 333 is sleeved on the elastic rod 332 and is in interference fit with the elastic rod 332, for limiting the elastic rod 332 on the mounting plate 21 of the mounting keel 2. That is, after the connecting part 33 is fixed on the mounting plate 21, the mounting plate 21 is located between the fixing ring 333 and the mounting block 331.

[0037] As Figure 5As shown, in order to facilitate the installation and removal of the monitor body 4, the electrical fire detector fixing support further comprises a mounting and fixing assembly 5 arranged on the fixing plate 1. Specifically, the mounting and fixing assembly 5 comprises a mounting groove 51, a limiting plate 52 and a pressing spring 53. The mounting groove 51 is arranged on the fixing plate 1 and located below the fixing plate 1, facilitating the installation of the monitor body. The limiting plate 52 is slidably arranged in the mounting groove 51, and the sliding direction of the limiting plate 52 is the up-down direction. The pressing spring 53 is arranged on the limiting plate 52. More specifically, two limiting plates 52 are arranged in parallel on the upper end and the lower end of the mounting groove 51. A plurality of pressing springs 53 are arranged equidistantly on the limiting plate 52 and abut against the inner top wall and the inner bottom wall of the mounting groove 51, i.e. the pressing springs 53 are arranged on the two opposite faces of the limiting plate 52 farthest apart. Further, in order to smoothly complete the installation of the monitor body, the electrical fire detector fixing support further comprises a mounting clamping block 6 arranged on the monitor body 4 and detachably mounted in the mounting groove 51. When it is necessary to install the monitor body on the fixing plate 1, it is only necessary to align the mounting clamping block 6 with the mounting groove 51, then abut the top surface or the bottom surface of the mounting clamping block 6 against the limiting plate 52, and push the limiting plate 52 to move upwards or downwards, so as to compress the pressing spring 53 located above or below, until the distance between the two limiting plates 52 is greater than the height of the mounting clamping block 6 and the mounting clamping block 6 can be accommodated therein, i.e. the force can be removed. Through the rebounding force of the pressing spring 53, the two limiting plates 52 above and below are tightly abutted against the mounting clamping block, so as to fix the mounting clamping block 6 in the mounting groove 51, and then stably fix the monitor body on the fixing plate 1.

[0038] When installing, the mounting block 6 on the monitor body 4 is fixed in the mounting groove 51 on the fixed plate 1 (the specific principle is described above), the connection between the monitor body and the fixed plate 1 is completed, then the fixed plug 34 is inserted into the plug-in groove 313 on the bearing plate 31, thereby realizing the connection between the bearing plate 31 and the fixed plate 1, then the L-shaped plate 32 is slid in the sliding groove 311, and the elastic clamping block 321 of the L-shaped plate 32 is fixed in the clamping groove 312 on the bearing plate 31, thereby realizing the connection between the L-shaped plate 32 and the bearing plate 31, the installation of the L-shaped plate 32 is completed, then the elastic rod 332 on the L-shaped plate 32 is inserted through the mounting through hole on the mounting plate 21, and the fixed ring 333 is sleeved on one end of the elastic rod 332, thereby completing the connection between the L-shaped plate 32 and the mounting plate 21, so that the monitor body 4 is connected with the mounting keel 2, and the installation of the electrical fire monitor is completed.
