A limiting rod 8 is fixed on one end of the fixing frame 5 close to the limiting slider 7, and the limiting rod 8 is slidably inserted in the limiting slider 7. A limiting spring 9 is sleeved on the limiting rod 8, and both ends of the limiting spring 9 are fixedly connected to the limiting slider 7 and the fixing frame 5 respectively. A detachable stopper 10 is engaged with the top of the fixing frame 5 close to the limiting rod 8, so that the disassembly of the detector body 1 is more convenient.
[0024] Specifically, the card plate 4 and the card slot 11 are set to be an inverted "L" shape that cooperate with each other. The top surface of the card plate 4 is flush with the top surface of the fixing frame 5, so that the fixing plate 6 limits the card plate 4, and the end of the fixing plate 6 close to the limiting slider 7 is set to be an "L" shape that cooperates with the limiting slider 7. The shape below the bottom end of the limiting slider 7 is an inverted "T" shape. The top surface of the fixing frame 5 is provided with a sliding groove that matches the shape of the limiting slider 7. The top surface and side surfaces of the limiting slider 7 are both provided with anti-slip stripes, so that the limiting slider 7 can engage and limit the fixing plate 6. The length of the limiting rod 8 is equal to the length of the bottom end of the limiting slider 7, and the length of the limiting rod 8 is greater than the length of the stop block 10. The shape of the stop block 10 is "L"-shaped, and the top of the fixing frame 5 is provided with a stop groove that matches the shape of the stop block 10, so that the stop block 10 can further limit the limit slider 7.
[0025] As an optimization solution, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the outer surface of the connection between the air inlet 2 and the air pipe 3 is symmetrically wrapped with a protection box 12, one side of the two protection boxes 12 is rotatably connected by a hinge, the top of one side of the protection box 12 is fixed to the bottom surface of the detector body 1, and the two sides of the protection boxes 12 away from the hinge are fixed by bolts, and the interfaces between the protection boxes 12, the air inlet 2 and the air pipe 3 are all engaged with rubber rings 13 to prevent leakage at the interface between the air inlet 2 and the air pipe 3.
[0026] Specifically, rubber pads are fixed to the opposite surfaces of the two protection chambers 12, and the opposite surfaces of the two protection chambers 12 are configured to be arc-shaped to match the air inlet 2 and the air pipe 3, so that the interior of the protection chamber 12 remains sealed.
[0027] Working principle: first fix the fixing frame 5 to the wall by expansion bolts or screws. When installing the detector body 1, align the card plate 4 with the card slot 11 and insert it into the card slot 11, slide the limit slider 7, and the limit spring 9 is forced to shrink. Rotate the fixing plate 6 so that the bottom surface of the fixing plate 6 fits with the top surface of the fixing frame 5, so as to limit and fix the card plate 4. Loosen the limit slider 7, the pressure on the limit spring 9 is released, and the limit spring 9 rebounds to push the limit slider 7 to reset, so that the limit slider 7 limits the fixing plate 6, and then engage the stopper 10 into the stopper groove, so that the stopper 10 limits the limit slider 7. When disassembling the detector body 1, take out the stopper. Block 10 to release the limit of the limit slider 7 by the stop block 10, slide the limit slider 7 again to release the limit of the fixed plate 6 by the limit slider 7, rotate the fixed plate 6 to release the fixation of the fixed plate 6 to the clamping plate 4, and then the detector body 1 can be taken out for maintenance. When in use, the protection bin 12 is opened by rotating the bolts on the side of the protection bin 12. When the air inlet 2 and the air pipe 3 are fixed, the protection bin 12 is closed and fixed by the bolts on the side. At this time, the rubber rings 13 at the upper and lower ends seal the interface between the air inlet 2 and the air pipe 3 inside the protection bin 12, and at the same time, the sealing rubber pad at the connection of the protection bin 12 keeps the inside of the protection bin 12 sealed.
