The number of moving rods 421 is two, and they are respectively arranged at one end inside the box body 41. One ends of the two moving rods 421 extend out of the box body 41 and are slidably connected to the box body 41. The clamping block 422 is arranged inside the box body 41 and is fixedly connected to one ends of the two moving rods 421. The lower end of the clamping block 422 extends out of the box body 41 and is slidably connected to the box body 41. The number of pushing springs 423 is two, and they are respectively sleeved on the surfaces of the two moving rods 421. Both ends of the two pushing springs 423 are fixedly connected to the inner surface of the box body 41 and the clamping block 422 respectively. The limiting plate 424 is fixedly connected to one ends of the two moving rods 421 that extend out of the box body 41.

[0026] With the above scheme: By setting the clamping component 42, it is used to fix the bottom shell 3, quickly connect the bottom shell 3 with the box body 41, facilitating the disassembly and assembly work during replacement and improving the portability of the detector.

[0027] Reference Figure 3 and Figure 4 , the linkage component 43 includes a pulling spring 431 and a pressing plate 432. The pulling spring 431 is arranged at the top inside the box body 41, and its upper end is fixedly connected to the inner top surface of the box body 41.

[0031] Reference Figure 1 and Figure 2 , a clamping groove 5 is formed on the surface of the bottom shell 3, and the position of the clamping groove 5 corresponds to the position of the clamping block 422.

[0032] Adopting the above solution: By opening a circumferential clamping groove 5 on the surface of the bottom shell 3 for cooperating and clamping with the clamping component 42, the bottom shell 3 can be fixed.

[0033] Reference Figure 3 and Figure 4 At one end where the rotating rod 442 extends out of the box body 41, a knob 6 is provided, and the knob 6 is fixedly connected to the rotating rod 442.

[0034] Adopting the above solution: By providing a knob 6 at one end where the rotating rod 442 extends out of the box body 41 to rotate the rotating rod 442, it is convenient to quickly twist the rotating rod 442 when disassembling the detector.

[0035] The working principle of the present utility model:

[0036] When replacing and installing the detector, align the body 1 with the middle position between the four clamping blocks 422 and press it upward. At the same time, the bottom shell 3 will squeeze the four clamping blocks 422, causing the clamping blocks 422 to move outward in the box body 41. While the clamping blocks 422 are moving, the moving rod 421 slides outward on the box body 41, and at the same time, the push spring 423 is compressed. When the bottom shell 3 is pushed up to contact the lower surface of the box body 41 with its upper surface, the clamping blocks 422 will correspond to the clamping grooves 5, and the clamping blocks 422 will no longer be squeezed. The push spring 423 rebounds and pushes the clamping blocks 422 together, and at the same time, the moving rod 421 slides into the box body 41. The upper ends of the clamping blocks 422 are pushed together and clamped into the clamping grooves 5 to complete the fixation. When replacing and disassembling the detector, by turning the knob 6, the rotating rod 442 is rotated in the sleeve 441. While the rotating rod 442 is rotating, the extrusion shaft 443 is rotated. The extrusion shaft 443 rotates to push the pressing plate 432 downward and at the same time stretches the tension spring 431. While the pressing plate 432 is being pushed downward, the upper ends of the four clamping blocks 422 are squeezed, causing the clamping blocks 422 to be squeezed and move outward in the box body 41 to open, thereby releasing the fixation of the bottom shell 3.

[0037] In summary: For this portable fire detection sensor for fire detection, by using the cooperation of the body 1, the detection head 2, the bottom shell 3, the fixing device 4, the box body 41, the clamping component 42, the moving rod 421, the clamping block 422, the push spring 423, the limiting plate 424, the linkage component 43, the tension spring 431, the pressing plate 432, the control component 44, the sleeve 441, the rotating rod 442, the extrusion shaft 443, the clamping groove 5 and the knob 6, it solves the problem that the existing fire detection sensors are usually fixed to the wall by screws as a whole. In this case, it is more troublesome to drive in screws again during maintenance and replacement, resulting in the loss of portability during maintenance and replacement.
