DETAILED DESCRIPTION

[0029] The present application is further described in detail below with reference to the accompanying drawings.

[0030] In the description of the invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the invention.

[0031] The present application embodiment discloses an electrical fire detector, referring to Figure 1 、 Figure 2 and Figure 3 The detector housing 10 includes a detection module, a detector housing 10, and a fixed slide 40. The detection module is placed within the detector housing 10. The fixed slide 40 has a pre-threaded hole, and the detector housing 10 is provided with an assembly slot 101 for the fixed slide 40 to be mounted. The assembly slot 101 cooperates with the fixed slide 40, allowing the detector housing 10 to be quickly positioned and mounted on the fixed slide 40. This is more convenient than traditional screw installation and improves installation efficiency.

[0032] Reference Figure 4 and Figure 5 The detector housing 10 is provided with a sliding stopper 20, which includes a pressing portion 201, one end of which extends into the assembly slide 101. The sliding stopper 20 also includes a limiting handle 203 provided below the pressing portion 201. A limiting block 204 is provided on the side of the limiting handle 203 close to the slope 202. The limiting block 204 presses against the edge of the pressing groove 401. The fixed slide 40 is provided with a pressing groove 401 on the side facing the sliding stopper 20. The pressing portion 201 is provided with a slope 202 on one end facing the pressing groove 401. The pressing portion 201 is slidably inserted into the pressing groove 401.

[0033] Reference Figure 6 and Figure 7By arranging the stop block 204 and the abutting portion 201, when the detector housing 10 and the fixed slide 40 are slidably mounted, the abutting portion 201 is inserted into the assembly slot 101, positioning the fixed slide 40. The stop block 204 abuts against the edge of the abutting slot 401, closing the gap between the sides of the fixed slide 40 and the detector housing 10, allowing the fixed slide 40 to slide more smoothly. A mounting slot 207 for mounting the sliding stop member 20 is defined within the detector housing 10. A clamping handle 205 is provided on each side of the abutting handle. The end of the clamping handle 205, away from the slope 202 and the stop block 204, is fixedly connected to the abutting portion 201 and the stop handle 203. There is a gap between the two clamping handles 205 and the limiting handle 203. The closer the clamping handles 205 are to the limiting block 204, the larger the gap between them. Both clamping handles 205 are provided with a slider 206 on the end facing the limiting block 204. A plurality of sliding slots 208 are symmetrically formed on both sides of the mounting slot 207, forming a corrugated shape. When the slider 206 is engaged in the sliding slot 208, the gap between the clamping handle 205 and the limiting handle 203 decreases. The slider 206 is configured to be wide at the top and narrow at the bottom. This configuration allows the slider 206 to slide only along the sliding slot 208 in a direction away from the assembly slot 101. Conversely, if the slider 206 moves toward the assembly slot 101, it will become stuck.

[0034] Reference Figure 8 and Figure 9 The detector housing 10 is also provided with a one-way limit assembly, which includes a movable pin 301, one end of which extends into the assembly slot 101. A one-way tooth 302 is formed on the end of the movable pin 301 near the fixed slide 40. The fixed slide 40 has a mating tooth 402 that engages with the one-way tooth 302, which is located within the assembly slot 101. A return spring 303 is provided on the end of the movable pin 301 away from the one-way tooth 302. An unlocking handle 304 is also fixed to the movable pin 301, one end of which is exposed outside the detector housing 10.

[0035] A guide block 103 is provided in the assembly slide 101 and on both sides of the movable pin 301. A guide groove 403 is provided on the side of the fixed slide 40 close to the movable pin 301. The mating tooth 402 is provided in the guide groove 403. The guide block 103 is inserted into the guide groove 403, so that the sliding between the fixed slide 40 and the detector housing 10 is smoother.

[0036] A through hole 209 is formed at one end of the slide stop 20, away from the abutting portion 201. The handle hole 209 is exposed in the mounting slot 207. The handle hole 209 is designed to facilitate operation of the slide stop 20 by maintenance personnel. The maintenance personnel can pull or push the slide stop 20 through the handle hole 209 to install and remove the detector housing 10.

[0037] An operating housing 104 protrudes from one side of the detector housing 10. Mounted on this housing is a display screen 106, adjacent to which are several control buttons 105. Display screen 106 is connected to the detection module via a cable and displays detection data and device status. The control buttons 105 are mechanical buttons used to set parameters and operate the electrical fire detector.

[0038] The implementation principle of the embodiment of the present application is as follows: The present application provides an electrical fire detector that facilitates quick disassembly and installation by maintenance personnel, thereby improving the maintenance efficiency of the electrical fire detector. Before achieving quick disassembly and installation, it is necessary to first install a fixed slide 40 and secure it to the wall of the building using the threaded holes reserved in the fixed slide 40.

[0039] Insert the sliding stopper 20 from the direction of the mounting slot 101 into the mounting slot 207. Press the abutting portion 201 or the stopper 204, pressing the slider 206 into the sliding slot 208. Adjust the length of the abutting portion 201 and the stopper 204 protruding from the mounting slot 101. If the length is not appropriate, pull downward through the handle hole 209 to adjust. As you pull and adjust, the slider 206 will slide along the corrugated sliding slot 208, making a clicking sound.

[0040] The detector housing 10 is slidably installed on the fixed slide 40. During this process, the setting of the movable pin 301 causes the one-way tooth 302 to contact the mating tooth 402. The one-way tooth 302 only allows the fixed slide 40 to move in one direction. If it moves in the opposite direction, the one-way tooth 302 and the mating tooth 402 will be stuck. The one-way tooth 302 moves along the mating tooth 402, and the return spring 303 repeats the process of compression, rebound, and recompression as it moves. Until the detector housing 10 is completely installed on the fixed slide 40. The movable pin 301 is stuck between the two mating teeth 402, locking the movement between the detector housing 10 and the fixed slide 40.

[0041] When the detector housing 10 is disassembled, the unlocking handle 304 is swung to compress the return spring 303, and then the detector housing 10 is pulled out. Through the above steps, the detector housing 10 can be quickly disassembled and assembled.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
