The fire alarm we often call is a type of fire alarm. According to the actual installation situation, fire alarm is generally installed in the corridors, stairways and other places with large traffic flow of buildings. When the fire alarm detects a fire, it will produce sound and flashing flames to alert people in the building.

[0003] At present, the installation form of fire alarms is mostly fixed, which makes it inconvenient to inspect and repair the fire alarms at regular intervals, thereby increasing the difficulty of inspection and repair and reducing work efficiency. Utility Model Content

[0015] 1. The utility model provides a fire monitoring and early warning device which is easy to install. By setting a positioning rod corresponding to the insertion in the positioning hole until the bottom end, the rotating gear drives the teeth to cause the slave gear to rotate. When the slave gear rotates, it can drive the positioning rod to rotate with it, causing the clamping block on the other end of the positioning rod to rotate in the rotating groove.

[0024] The present invention is further described in detail below in conjunction with the embodiments:

[0025] Example 1

[0026] like Figure 1-5As shown, the utility model provides a fire monitoring and early warning device that is easy to install, including a fire monitoring and early warning device body 1, the fire monitoring and early warning device body 1 includes a chassis 2, a connecting plate 3 is detachably installed in front of the chassis 2, fixing components 4 are arranged on all sides of the chassis 2, disassembly units are arranged on all sides of the connecting plate 3, and fixing units are arranged on both sides of the top of the connecting plate 3. The disassembly unit includes a clamping groove 21 arranged on the front of the chassis 2, and positioning holes 23 are opened on the inner periphery of the clamping groove 21. A rotating groove 24 is opened on the inner bottom end of the positioning hole 23, and the connecting plate 3 is rotatably mounted on all four sides in front of the connecting disk 3, a rotating gear 32 is rotatably mounted on the middle position in front of the connecting disk 3, teeth 33 are fixedly mounted on all four sides of the rotating gear 32, and a fixing hole 34 is opened on the outer surface of the teeth 33. An early warning device 35 is arranged in front of the rotating gear 32, and a positioning rod 36 is fixedly mounted on the output end of the slave gear 31 on all four sides of the rear of the connecting disk 3, and a clamping block 37 is fixedly mounted on the other end of the positioning rod 36, the positioning rod 36 is movably inserted into the interior of the positioning hole 23, and the clamping block 37 is rotatably connected to the interior of the rotating groove 24.

[0027] Furthermore, by installing the chassis 2 in the required position in conjunction with the fixing component 4, the chassis 2 does not need to be disassembled during maintenance. When installing the early warning device 35, it is only necessary to insert the positioning rods 36 on the four sides of the rear of the connecting plate 3 into the interior of the positioning hole 23 until the bottom end. At this time, the rotating gear 32 uses the teeth 33 to drive the slave gear 31 to rotate. When the slave gear 31 rotates, it can drive the positioning rod 36 to rotate with it, causing the clamping block 37 on the other end of the positioning rod 36 to rotate inside the rotating groove 24, and the rotating groove 24 is used to limit the clamping block 37.

[0028] Example 2

[0029] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a resistance groove 22 is opened in the front of the chassis 2 at the inner middle position of the locking groove 21, a reset spring 39 is fixedly installed in the rear middle position of the connecting plate 3, and a resistance plate 38 is fixedly installed on the other end of the reset spring 39, and the resistance plate 38 is movably inserted in the inside of the resistance groove 22.

[0030] Furthermore, after the connection, the abutment plate 38 behind the connecting plate 3 abuts against the inside of the abutment groove 22 under the elastic force of the reset spring 39, and the elastic potential energy of the reset spring 39 causes the chassis 2 and the connecting plate 3 to be subjected to an extrusion force to prevent the existence of a gap between them and cause shaking, thereby making the installation stable.

[0031] Example 3

[0032] like Figure 1-5As shown, on the basis of Examples 1-2, the utility model provides a technical solution: preferably, the fixing unit includes mounting blocks 310 arranged on both sides of the top front of the connecting plate 3, a piston rod 311 is fixedly mounted on the inner side of the mounting block 310, a fixing sleeve 312 is movably sleeved on the other end of the piston rod 311, the fixing sleeve 312 is detachably inserted into the inside of the fixing hole 34, a toggle block 313 is fixedly mounted on the top of the fixing sleeve 312, and an elastic wire 314 is movably sleeved on the outer surface of the piston rod 311.

[0033] Furthermore, by releasing the toggle block 313, the fixed sleeve 312 slides on the outer surface of the piston rod 311 under the elastic driving force of the elastic wire 314, causing the fixed sleeve 312 to come into contact with the fixed hole 34 inside the tooth 33, thereby limiting the rotating gear 32 and preventing it from rotating.

[0034] The following is a detailed description of the working principle of this easy-to-install fire monitoring and early warning device.

[0035] like Figure 1-5 As shown, when in use, the chassis 2 is installed in the required position by cooperating with the fixing component 4. When repairing, the chassis 2 does not need to be disassembled. When installing the early warning device 35, it is only necessary to insert the positioning rods 36 on the four sides of the rear of the connecting plate 3 into the interior of the positioning hole 23 until the bottom end. At this time, the rotating gear 32 uses the teeth 33 to drive the slave gear 31 to rotate. When the slave gear 31 rotates, it can drive the positioning rod 36 to rotate with it, so that the clamping block 37 on the other end of the positioning rod 36 rotates inside the rotating groove 24, and the rotating groove 24 is used to limit the clamping block 37, and then By releasing the toggle block 313, the fixed sleeve 312 slides on the outer surface of the piston rod 311 under the elastic pushing force of the elastic wire 314, causing the fixed sleeve 312 to abut against the fixed hole 34 inside the tooth 33, thereby limiting the rotating gear 32 and preventing it from rotating. After the connection, the abutment plate 38 behind the connecting plate 3 abuts against the inside of the abutment groove 22 under the elastic force of the reset spring 39, and the elastic potential energy of the reset spring 39 causes the chassis 2 and the connecting plate 3 to be subjected to a squeezing force to prevent the gap between them from causing shaking, thereby making the installation stable.

[0036] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
