Description

Technical Field

[0001] The utility model relates to the technical field of smoke detectors, in particular to a building smoke detector. Background Art

[0002] Smoke detectors mainly prevent fires by monitoring the concentration of smoke. Smoke detectors use ion smoke sensors inside. Installing smoke detectors in buildings can monitor fires and issue alarms in time to remind people to evacuate after a fire occurs.

[0003] After searching, the patent number is CN215674378U, and the name is a utility model of an independent smoke detector, which includes a mounting base, and a lifting support is provided directly below the mounting base. Through research and analysis, it is found that although the height of the smoke detection head inside can be regulated, so that its working range is expanded, large particles in the smoke can be filtered and removed, and large particles in the smoke are prevented from adhering to the smoke detection head and affecting the detection sensitivity, the following defects still exist to a certain extent.

[0004] For example, it is not convenient to quickly disassemble and assemble the smoke detector. The above-mentioned smoke detector needs to be installed and fixed with screws. Such disassembly and assembly requires the use of tools, which is time-consuming and laborious for personnel to operate, affecting the disassembly and assembly efficiency. In addition, it does not have dust and insect-proof functions, and it is not convenient to clean dust and debris. In order to solve the above technical problems, we have designed a building smoke detector. Utility Model Content

[0005] The purpose of the utility model is to provide a building smoke detector, which has the function of quick disassembly and assembly, reduces the workload of personnel, has dust and insect prevention functions, and is convenient to clean, and solves the problems of time-consuming and labor-intensive disassembly and assembly, affecting the disassembly and assembly efficiency, and lacks dust and insect prevention functions, making it inconvenient to clean.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a building smoke detector, comprising a mounting shell, the top of the mounting shell is fixedly connected with a plug-in mechanism, the outer surface of the plug-in mechanism is slidably sleeved with a positioning plug-in shell, the bottom of the mounting shell is fixedly connected with a supporting vertical plate, the bottom of the supporting vertical plate is fixedly connected with a fixed bottom shell, a protective mesh plate is fixedly connected between the left and right supporting vertical plates, the four corners of the bottom of the mounting shell are fixedly connected with supporting sliding rods, the surface of the supporting sliding rod is slidably connected with a cleaning mechanism, and the inner cavity of the mounting shell is fixedly connected with a detector body.

[0007] Preferably, the cleaning mechanism comprises a connecting ring, a cleaning sponge block is fixedly glued to the inner side of the connecting ring, and push plates are glued to the front and rear sides of the connecting ring.

[0008] Preferably, the plug-in mechanism includes a fixed shell, and connecting slides are slidably connected to the left and right sides of the inner cavity of the fixed shell, a supporting spring is fixedly connected between the left and right connecting slides, and a movable plug plate is fixedly connected to the side of the connecting slide away from the supporting spring, and the side of the movable plug plate away from the connecting slide passes through to the outside of the positioning plug shell and is chamfered.

[0009] Preferably, the four corners of the positioning plug shell are fixedly connected with positioning blocks, and the left and right sides of the positioning plug shell are provided with limited openings.

[0010] Preferably, the bottom of the supporting slide bar is fixedly connected to the fixed bottom shell, and the number of the protective mesh plates is several.

[0011] Preferably, an alarm is penetrated and fixedly connected to the front side of the bottom of the fixed bottom shell, and an indicator light module is penetrated and fixedly connected to the rear side of the bottom of the fixed bottom shell.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The rear side of the plug-in mechanism is inserted from the opening on the front side of the positioning plug-in shell, and pushed backward with force. When the movable plug-ins on both sides move to align with the limit openings on both sides, the support spring releases elastic potential energy to push the movable plug-ins on both sides to be inserted into the limit openings on both sides respectively, so that the fixed shell can be limited. When maintenance or replacement is required, just continue to push backward with force, and the fixed shell is moved out from the opening on the rear side of the positioning plug-in shell, which makes disassembly and assembly more convenient and quick.

[0014] 2. By setting up a protective mesh, debris and flying insects can be prevented from entering the interior of the installation shell, and the detector body can be protected from dust and insects. Push the connecting ring up and down, so that the cleaning sponge block inside the connecting ring can clean and wipe the outer surface of the protective mesh, and sweep away the dust and debris attached to the surface, making the operation more time-saving and labor-saving.
