Description

Technical Field

[0001] The utility model relates to the technical field of alarms, in particular to an explosion-proof sound and light alarm. Background Art

[0002] An alarm refers to an instrument that issues alarm signals, and is used to issue forecast, warning and alarm cancellation signals. Among them, an explosion-proof sound and light alarm is a sound and light alarm device installed on site. When an accident or fire or other emergency situation occurs at the production site and an sound and light alarm prompt is required, the explosion-proof sound and light alarm device is activated through a control signal, and the explosion-proof sound and light alarm device can then issue sound and light alarm signals to complete the alarm prompt purpose.

[0003] However, when the prior art is actually used, during the installation process, the explosion-proof sound and light alarm is usually suspended and fixed at the desired installation position by embedded bolts or screws. When the explosion-proof sound and light alarm is suspended and fixed by embedded bolts or screws, when it is necessary to disassemble, repair or replace the explosion-proof sound and light alarm, the operator needs to use a disassembly tool to disassemble the suspended and fixed explosion-proof sound and light alarm, which makes it inconvenient to disassemble the explosion-proof sound and light alarm, especially during high-altitude operations, which affects the disassembly efficiency of the explosion-proof sound and light alarm and increases the disassembly risk of the operator. Utility Model Content

[0004] The purpose of the utility model is to provide an explosion-proof sound and light alarm to solve the problem that during the installation process of the explosion-proof sound and light alarm proposed in the above-mentioned background technology, the explosion-proof sound and light alarm is usually suspended and fixed at the desired installation position by pre-embedded bolts or screws. When the explosion-proof sound and light alarm is suspended and fixed by pre-embedded bolts or screws, when it is necessary to disassemble, repair or replace the explosion-proof sound and light alarm, the operator needs to hold a disassembly tool to disassemble the suspended and fixed explosion-proof sound and light alarm, which makes it inconvenient to disassemble the explosion-proof sound and light alarm, especially during high-altitude operations, which affects the disassembly efficiency of the explosion-proof sound and light alarm and increases the disassembly risk problem for the operator.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: including an installation base plate, an explosion-proof sound and light alarm body and a push button, a limited straight slide groove is provided in the middle of the lower end surface of the installation base plate, a slide rod is fixedly connected to the rear bottom surface of the limited straight slide groove, a slider is sleeved on the front end outer curved surface of the slide rod, a main spring is sleeved on the rear end outer curved surface of the slide rod, an installation slide groove is provided on the side of the middle part of the front end surface of the installation base plate, a square pin hole is provided on the side wall of the installation slide groove, a square pin block is inserted into the inner wall of the square pin hole, and a secondary spring is fixedly connected to the side of the square pin block away from the end of the limited straight slide groove.

[0006] Preferably, four installation opening grooves are provided at the four corners of the lower end surface of the installation base plate, and there are four installation opening grooves, which are symmetrically distributed at the four corners of the lower end surface of the installation base plate, and a mounting hole is provided through the middle of the top surface of the installation opening groove.

[0007] Preferably, the limiting straight slide groove passes forward through the middle of the front end surface of the mounting base plate, and the outer sides of both sides of the sliding block are movably connected to the inner wall of the limiting straight slide groove.

[0008] Preferably, the rear top end of the main spring is fixedly connected to the rear bottom surface of the limiting straight sliding groove, and the main spring is in a compressed state, and the front top end of the main spring is movably connected to the rear end surface of the sliding block.

[0009] Preferably, the explosion-proof sound and light alarm body is fixedly connected to the lower bottom surface of the slider.

[0010] Preferably, the square pin hole penetrates to the inner wall of the front end of the limiting straight sliding groove, and the inner side of the rear end surface of the square pin block fits and blocks the front end surface of the sliding block.

[0011] Preferably, there are two auxiliary springs, which are symmetrically distributed on the sides of the square pin block. The push button is fixedly connected to the side of the front end surface of the square pin block, and the front end of the push button extends out of the front end opening of the installation slot.

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

[0013] The utility model keeps the slider fixed on the inner wall of the limit straight slide groove and keeps the main body of the explosion-proof sound and light alarm fixed by blocking the inner side of the rear end face of the square pin block and compressing and pushing the main spring. The side face of the square pin block away from the limit straight slide groove is bonded with a secondary spring, and there are two secondary springs, which are symmetrically distributed on the side faces of the square pin block. The push button is bonded to the side face of the front end face of the square pin block, and the front end of the push button extends out of the front end opening of the installation slide groove, so that by pushing the push button outward, when the push button is pushed outward, the square pin block will be driven to move outward. When the square pin block moves outward, the square pin block will no longer block the slider, so that the slider drives the main body of the explosion-proof sound and light alarm to automatically move outward and be disassembled through the thrust of the main spring, thereby realizing the effect of facilitating the disassembly of the main body of the explosion-proof sound and light alarm.

[0014] The utility model also can reinstall and fix the explosion-proof sound and light alarm body when it is necessary to push the push button outwards. When the push button drives the square pin block to move outwards, the slider is reinserted into the outer curved surface of the slide bar and the inner wall of the limiting straight slide groove. At the same time, when the square pin block moves outwards, it pushes the compressed secondary spring. Therefore, when the force pushing the push button outwards is released, the square pin block is re-inserted into the front end inner wall of the limiting straight slide groove under the thrust generated by the compression of the secondary spring, so that the slider drives the explosion-proof sound and light alarm body to remain locked and fixed, thereby facilitating the disassembly of the explosion-proof sound and light alarm body and facilitating the resetting and installation of the explosion-proof sound and light alarm body.
