[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please refer to Figure 1-5 As shown, this utility model provides an electrical fire monitoring device, including a base plate 1. An upper limit plate 3 and a lower limit plate 4 are respectively provided on one side of the base plate 1 near the upper and lower ends. A monitor body 5 is placed between the upper limit plate 3 and the lower limit plate 4. The two sides of the monitor body 5 are connected to the base plate 1 through a snap-fit ​​mechanism that is easy to disassemble and assemble. A locking mechanism is provided on the outside of the wiring port of the monitor body 5 to facilitate the fixing of the wiring.

[0022] Specifically, the base plate 1 can limit the position of the monitor body 5 through the upper limit plate 3 and the lower limit plate 4. The monitor body 5 can be quickly installed and removed from the base plate 1 through the snap-fit ​​mechanism on both sides. When wiring, the wire can be locked and fixed by the locking mechanism after being led out from the wiring port of the monitor body 5. The monitor body 5 can monitor the electrical circuit parameters in real time. When leakage, overload or abnormal temperature is detected, an alarm signal is immediately issued. Thus, through the above structure, the installation convenience of the electrical fire monitoring device and the reliability of the wiring fixation are effectively improved.

[0023] The locking mechanism includes an arc-shaped locking plate 9 and an arc-shaped locking block 14. L-shaped mounting bases 12 are installed on both sides of the monitor body 5. Connecting blocks 13 are installed at the bottom of each of the two sets of mounting bases 12. An arc-shaped locking block 14 is located at the center of the bottom of each of the two sets of connecting blocks 13. Two sets of bases 6 are installed on one side of the base plate 1. A groove 7 is opened on one side of each of the two sets of bases 6. A fixing shaft 8 is located inside each of the two sets of grooves 7. Two sets of opposing arc-shaped locking plates 9 are rotatably connected to the outer rings of the two sets of fixing shafts 8. A protruding plate 10 is located on one side of each of the two sets of arc-shaped locking plates 9. Both protruding plates are connected to the base 6 via springs 11. When installing the monitor body 5, the arc-shaped locking blocks at the bottom of the connecting blocks 13 on both sides are... 14 Aligns the two sets of opposing arc-shaped clamping plates 9 on the base 6. By pressing the monitor body 5, the arc-shaped clamping block 14 can squeeze the two sets of arc-shaped clamping plates 9 to rotate around the fixed axis 8 and drive the convex plate 10 to compress the spring 11. When the arc-shaped clamping block 14 passes the arc-shaped clamping plate 9, under the action of the spring 11's rebound force, the two sets of arc-shaped clamping plates 9 can automatically reset and clamp the arc-shaped clamping block 14, thereby completing the quick installation of the monitor body 5. When disassembling, applying reverse force to make the arc-shaped clamping plate 9 rotate again can release the arc-shaped clamping block 14, thereby quickly removing the monitor body 5. Thus, by setting it up, the monitor body 5 can be quickly disassembled and assembled, ensuring both installation stability and easy maintenance and repair.

[0024] The locking mechanism includes a locking seat 17. A fixing ring 15 is provided on the outer side of the wiring port of the monitor body 5. One end of the fixing ring 15 is provided with three sets of arc-shaped threaded plates 16. All three sets of threaded plates 16 are threadedly connected to the locking seat 17. The internal thread of the locking seat 17 is tapered. During installation, after the wire passes through the locking seat 17 and the three sets of arc-shaped threaded plates 16 on the fixing ring 15, the locking seat 17 is rotated. Because the internal thread of the locking seat 17 is tapered, its rotation will push the three sets of arc-shaped threaded plates 16 to retract inward along one end of the fixing ring 15, thereby clamping and fixing the wire that has passed through. This achieves the locking operation of the wire at the wiring port of the monitor body 5. Thus, by setting up the mechanism, the wire at the wiring port can be conveniently locked and reliably fixed, preventing the wire from becoming loose and affecting the operation of the monitoring device.

[0025] The lower limit plate 4 has a notch 18 on one side below the wiring port of the monitor body 5. The notch 18 on the lower limit plate 4 can provide enough space for the operation of the locking mechanism. The bottom of the upper limit plate 3 and the top of the lower limit plate 4 are provided with anti-slip pads. The anti-slip pads can increase the friction with the monitor body 5, prevent the monitor body 5 from shaking or shifting after installation, and improve the stability of the device installation.

[0026] The base plate 1 has mounting holes 2 near its four corners. These mounting holes 2 at the four corners of the base plate 1 facilitate fixing the device to the wall, distribution cabinet, or other mounting surfaces using bolts or screws, thereby improving the convenience and stability of the installation.

[0027] Working principle: First, the base plate 1 is fixed to the mounting surface through the mounting holes 2 at the four corners. Then, the monitor body 5 is placed between the upper limit plate 3 and the lower limit plate 4. The anti-slip pad increases friction to prevent displacement. Next, the arc-shaped locking blocks 14 at the bottom of the connecting blocks 13 on both sides are aligned with the two sets of opposing arc-shaped locking plates 9 on the base 6. By pressing the monitor body 5, the arc-shaped locking blocks 14 can squeeze the two sets of arc-shaped locking plates 9 to rotate around the fixed axis 8, which in turn drives the convex plate 10 to compress the spring 11. When the arc-shaped locking blocks 14 pass the arc-shaped locking plates 9, the two sets of arc-shaped locking plates 9 can automatically reset under the rebound force of the spring 11. The arc-shaped locking block 14 is clamped to allow for quick installation of the monitor body 5. During disassembly, applying reverse force causes the arc-shaped locking plate 9 to rotate again, releasing the arc-shaped locking block 14 and allowing for quick removal of the monitor body 5. After the wires pass through the locking seat 17 and the three sets of arc-shaped threaded plates 16 on the fixing ring 15, rotating the locking seat 17 causes the three sets of arc-shaped threaded plates 16 to retract inward along one end of the fixing ring 15 due to the conical internal thread of the locking seat 17. This clamps and fixes the wires passing through, thus locking the wires at the connection port of the monitor body 5 and completing the entire operation.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
