Description

Technical Field

[0001] The utility model relates to the technical field of fire detectors, in particular to a multifunctional temperature-sensitive fire detector. Background Art

[0002] Fire detectors mainly use thermistors to detect fires. In the initial stage of a fire, on the one hand, a large amount of smoke is generated, and on the other hand, a large amount of heat is released during the combustion process. The ambient temperature rises sharply, and the thermistor in the detector undergoes physical changes, responding to abnormal temperature, temperature rate, and temperature difference, thereby converting the temperature signal into an electrical signal and performing alarm processing.

[0003] The inventor believes that the following defects often exist: when the staff needs to perform regular maintenance on the fire detector, the staff needs to use a ladder to disassemble the fire detector, and sometimes the staff needs to use both hands to cooperate in the operation to disassemble and repair the fire detector, which poses certain safety hazards during work; therefore, a multifunctional temperature-sensitive fire detector is proposed to address the above problems. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a multifunctional temperature-sensing fire detector, comprising a detector body, a temperature sensor is installed inside the detector body, an alarm is installed inside the detector body, a protective shell is installed on the surface of the detector body, the side wall of the detector body is electrically connected with a connecting wire, a snap-in groove is provided on the surface of the detector body, a disassembly device is provided on the inner surface of the snap-in groove of the detector body, the disassembly device comprises a snap-in plate, a semicircular plate is fixedly connected to the side of the snap-in plate away from the protective shell, the snap-in plate is made of a soft material, a connecting hole is provided on the side wall of the detector body, the snap-in groove of the detector body is connected to the connecting hole, three mounting grooves are provided on the surface of the detector body, a mounting rod is slidably connected to the inner surface of the mounting groove of the detector body, and the mounting rod is fixedly connected to the protective shell.

There are certain safety risks when workers disassemble the detector body, thereby improving the practicality of the device.

[0007] Preferably, a spring is fixedly connected to the inner surface of the clamping plate.

[0008] The effect achieved by the above components is that the clamping plate is automatically ejected under the action of the spring, thereby increasing the service life of the clamping plate.

[0010] The effect achieved by the above components is: achieving the effect of squeezing the semicircular plate, making it easier for staff to remove the protective shell from the detector body, thereby improving the practicability of the device.

[0011] Preferably, the arc surface of the rotating rod is sleeved with two torsion springs, and two ends of the torsion springs are fixedly connected to the connecting plate and the U-shaped plate respectively.

[0013] Preferably, a sealing gasket is adhered to the surface of the detector body, and the sealing gasket fits the surface of the protective shell.

[0014] The effect achieved by the above components is: the protective shell is sealed when connected to the detector body, which prevents water vapor in the air from entering the interior of the detector body due to large temperature differences in the room, thereby affecting the normal operation of the detector body, thereby improving the practicability of the device.

[0016] The effect achieved by the above components is: by setting up the clamping device, the connecting wires electrically connected to the detector body are clamped and fixed, avoiding the loosening of the connecting wires when connected to the detector body for a long time, thereby affecting the normal use of the detector body, and improving the practicality of the device.

[0017] Preferably, one end of the abutment plate close to the fixed plate is fixedly connected with a sliding rod, and the arc surface of the sliding rod is slidably connected to the fixed plate.

[0018] The effect achieved by the above components is: avoiding the situation where the rotating threaded rod drives the abutment plate to rotate, resulting in the abutment plate being unable to effectively clamp and fix the connecting line, thereby improving the practicality of the device.

By setting the disassembly device 4, the detector body 1 and the protective shell 2 can be quickly disassembled and installed, which avoids the need for workers to climb up a ladder and use both hands to disassemble the detector body 1 when inspecting the detector body 1, and there are certain safety risks when the workers disassemble the detector body 1, thereby improving the practicality of the device. The side wall of the detector body 1 is provided with a clamping device 5. By setting the clamping device 5, the connecting line 3 electrically connected to the detector body 1 can be clamped and fixed, which avoids the loosening of the connecting line 3 when it is connected to the detector body 1 for a long time, thereby affecting the normal use of the detector body 1, thereby improving the practicality of the device.

[0029] The specific arrangement and function of the disassembling device 4 and the clamping device 5 will be described in detail below.

[0030] Reference Figure 2 , Figure 3 and Figure 4As shown, in this embodiment: the disassembly device 4 includes a clamping plate 401, and a semicircular plate 402 is fixedly connected to the side of the clamping plate 401 away from the protective shell 2. The material of the clamping plate 401 is a soft material. A connecting hole 403 is provided on the side wall of the detector body 1. The clamping groove of the detector body 1 is connected to the connecting hole 403. Three mounting grooves are provided on the surface of the detector body 1. A mounting rod 404 is slidably connected to the inner surface of the mounting groove of the detector body 1. The mounting rod 404 is fixedly connected to the protective shell 2. A spring 405 is fixedly connected to the inner surface of the clamping plate 401. Under the action of the spring 405, the clamping plate 401 is automatically ejected, thereby increasing the service life of the clamping plate 401. A U-shaped plate 406 is fixedly connected to the side wall of the detector body 1. A rotating rod 407 is rotatably connected to the U-shaped plate 406. The arc surface of the rotating rod 407 is fixedly connected to a connecting plate 408. A contact rod 409 is fixedly connected to one side of the connecting plate 408. The circular plate 402 is slidably connected, which achieves the effect of squeezing the semicircular plate 402, making it convenient for the staff to remove the protective shell 2 from the detector body 1, thereby improving the practicability of the device. The arc surface of the rotating rod 407 is sleeved with two torsion springs 410, and the two ends of the torsion spring 410 are respectively fixedly connected to the connecting plate 408 and the U-shaped plate 406. Under the action of the torsion spring 410, the connecting plate 408 is automatically opened and maintained at a certain angle, thereby avoiding the abutment rod 409 being in the connecting hole 403, which is inconvenient for the protective shell 2 to be installed with the detector body 1, thereby improving the practicability of the device. A sealing gasket 411 is adhered to the surface of the detector body 1, and the sealing gasket 411 fits with the surface of the protective shell 2, thereby achieving the effect of sealing when the protective shell 2 is connected to the detector body 1, thereby avoiding the situation where water vapor in the air enters the interior of the detector body 1 due to the large temperature difference in the room, thereby affecting the normal operation of the detector body 1, thereby improving the practicability of the device.

[0031] Reference Figure 5 As shown, specifically, the clamping device 5 includes a support plate 51, which is fixedly connected to the side wall of the detector body 1, a support plate 52 is fixedly connected to the surface of the support plate 51, a fixing plate 53 is fixedly connected to the side wall of the detector body 1, a threaded rod 54 is inserted into the internal thread of the fixing plate 53, one end of the threaded rod 54 is rotatably connected to an abutment plate 55, and one end of the abutment plate 55 close to the fixing plate 53 is fixedly connected to a slide rod 56, and the arc surface of the slide rod 56 is slidably connected to the fixing plate 53, thereby avoiding the situation where the rotating threaded rod 54 drives the abutment plate 55 to rotate, resulting in the abutment plate 55 being unable to effectively clamp and fix the connecting line 3, thereby improving the practicability of the device.

[0032] Working principle: when the staff needs to install the detector body 1, the detector body 1 and the protective shell 2 are assembled and fixed on the wall. When the staff needs to disassemble and repair the detector body 1, the staff climbs up the ladder to operate the detector body 1. The staff pushes the connecting plate 408 with the thumb, and the connecting plate 408 drives the rotating rod 407 to rotate in the U-shaped plate 406. The connecting plate 408 drives the abutting rod 409 to squeeze the semicircular plate 402, and the semicircular plate 402 drives the clamping plate 401 to compress the spring 405, and then Afterwards, the staff pulls the protective shell 2 to drive the snap-on plate 401 and the mounting rod 404 to be removed from the detector body 1. When the connecting plate 408 is not subjected to force, it automatically pops open under the action of the torsion spring 410, thereby achieving the effect of quickly disassembling the detector body 1 and the protective shell 2. This avoids the need for the staff to climb up a ladder and use both hands to disassemble the detector body 1 when inspecting the detector body 1. There are certain safety risks when the staff disassemble the detector body 1, thereby improving the practicability of the device.

[0033] When the staff needs to clamp and fix the connecting wire 3, the threaded rod 54 is rotated in the fixed plate 53, the threaded rod 54 drives the abutment plate 55 to move, and the abutment plate 55 drives the sliding rod 56 to slide in the fixed plate 53 until the abutment plate 55 fits with the surface of the connecting wire 3, thereby achieving the effect of clamping and fixing the connecting wire 3 electrically connected to the detector body 1, avoiding the connecting wire 3 from loosening when connected to the detector body 1 for a long time, thereby affecting the normal use of the detector body 1, and improving the practicability of the device.
