Description

Technical Field

[0001] The utility model relates to the technical field of fire alarms, and in particular to an Internet of Things fire alarm. Background Art

[0002] A fire alarm is an electronic device used to detect fires and sound alarms. When it detects large amounts of smoke or abnormal heat that may cause a fire, it can warn people through sounds, flashes of light, etc., to remind people on the scene to pay attention and take appropriate safety measures. An IoT fire alarm is a fire alarm device that uses IoT technology. It can transmit fire alarm information in real time through the network to a fire monitoring center or other designated receiving terminals, realizing remote monitoring and alarm functions. In daily work, the fire alarm needs to be maintained to check whether the fire alarm is still in normal use.

[0003] The fire alarm in the prior art is usually fixed to the wall by bolts. Each time the fire alarm is inspected and repaired, multiple bolts need to be unscrewed for disassembly, which is very cumbersome. In addition, the screw holes on the wall that match the bolts are prone to incompatibility with the bolts after repeated use, resulting in unstable fixation of the fire alarm. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an Internet of Things fire alarm.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: an Internet of Things fire alarm, including a fixing plate fixed to a wall, a mounting base fixed at the bottom of the fixing plate, a sleeve that is plugged into the mounting base is sleeved on the mounting base, an Internet of Things alarm is arranged at the bottom of the sleeve, a mounting hole is penetrated through the side wall of the mounting base, two fixing grooves that are plugged into the mounting hole are arranged on the inner wall of the sleeve, two symmetrically arranged fixing blocks are slidably connected in the mounting hole, the two fixing blocks are respectively plugged into the two fixing grooves, and a moving component for moving the two fixed blocks is installed on the mounting base.

[0006] By adopting the above technical solution, the two fixing blocks are respectively inserted into the two fixing grooves, so that the sleeve and the Internet of Things alarm are fixed on the mounting base. When the Internet of Things alarm needs to be disassembled, the staff only needs to drive the two fixing blocks to move closer to each other through the moving assembly, so that the two fixing blocks are disengaged from the fixing grooves and enter the mounting holes, thereby removing the sleeve and the Internet of Things alarm, eliminating the tedious operation of disassembling through multiple bolts, and facilitating the maintenance and repair of the Internet of Things alarm.

[0007] Furthermore, a socket is provided at the intersection between the top of the sleeve and the side wall of the sleeve, and the movable assembly includes a cross bar that is penetrated and slidably connected to the side wall of the mounting seat, a slider that is slidably connected to the inner wall of the mounting hole and fixed to the end of the cross bar, a pulling block fixed to the end of the cross bar away from the slider, and a connecting rod that is rotatably connected to the side wall of the slider, and two connecting rods are provided and symmetrically arranged on the side walls on both sides of the slider, and the ends of the two connecting rods away from the slider are respectively rotatably connected to the side walls of the two fixed blocks, and the cross bar is slidably connected to the inner wall of the socket.

[0008] By adopting the above technical solution, when the Internet of Things alarm needs to be disassembled, the staff pulls the cross bar and the slider outward through the pulling block. Since the slider is rotatably connected to the connecting rod, the connecting rod is rotatably connected to the fixed block, and the fixed block is slidably connected to the inner wall of the mounting hole, the two connecting rods pull the two fixed blocks to move closer to each other, thereby causing the two fixed blocks to detach from the fixing groove and enter the mounting hole, which is convenient for quickly disassembling the sleeve and the Internet of Things alarm.

[0009] Furthermore, a spring is arranged in the mounting hole, the spring is sleeved on the cross bar, one end of the spring is fixed to the inner wall of the mounting hole, and the other end of the spring is fixed to the side wall of the slider.

[0010] By adopting the above technical solution, the slider is pressed against the inner wall of the mounting hole under the elastic force of the spring, so that the fixed block remains plugged into the fixed groove, reducing the probability of the fixed block detaching from the fixed groove due to the movement of the slider, thereby reducing the probability of the sleeve and the Internet of Things alarm falling off.

[0011] Furthermore, a rubber pad is fixed to the inner wall of each fixing groove.

[0012] By adopting the above technical solution, the rubber pad is made of rubber material, and its surface has a large friction coefficient. The fixed block cooperates with the fixed groove and presses against the rubber pad, which increases the friction between the fixed block and the fixed groove and enhances the fixing effect of the fixed block on the sleeve.

[0013] Furthermore, a chamfer is formed on the side wall of each fixing block away from the connecting rod.

[0014] By adopting the above technical solution and the chamfered corners, the difficulty of aligning the fixing block with the fixing groove is reduced, making it easier to align and plug the fixing block with the fixing groove.

[0015] Furthermore, an upper magnetic block is embedded in the bottom of the mounting seat, and a lower magnetic block that is magnetically attracted to the upper magnetic block is embedded in the inner bottom wall of the sleeve.

[0016] By adopting the above technical solution, when disassembling the sleeve and the Internet of Things alarm, after the fixing block is separated from the fixing groove, the sleeve is still adsorbed on the mounting seat, which reduces the probability of the sleeve and the Internet of Things alarm accidentally falling and enhances the stability of the Internet of Things alarm.

[0017] Furthermore, an annular rubber sheet is fixed to the bottom of the fixing plate, and the annular rubber sheet is sleeved on the mounting seat.

[0018] By adopting the above technical solution, the annular rubber sheet is made of rubber material, which is elastic. The top of the sleeve cooperates with the bottom of the fixed plate and presses against the annular rubber sheet, reducing the wear between the top of the sleeve and the bottom of the fixed plate.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In the present application, the two fixing blocks are respectively inserted into the two fixing grooves, so that the sleeve and the IoT alarm are fixed on the mounting seat. When the IoT alarm needs to be disassembled, the staff only needs to drive the two fixing blocks to move closer to each other through the moving assembly, so that the two fixing blocks are separated from the fixing grooves and enter the mounting holes, thereby removing the sleeve and the IoT alarm, eliminating the tedious operation of disassembling through multiple bolts, and facilitating the maintenance and repair of the IoT alarm;

[0021] 2. In this application, when the IoT alarm needs to be disassembled, the staff pulls the crossbar and the slider outward through the pulling block. Since the slider is rotatably connected to the connecting rod, the connecting rod is rotatably connected to the fixed block, and the fixed block is slidably connected to the inner wall of the mounting hole, the two connecting rods pull the two fixed blocks to move closer to each other, so that the two fixed blocks are separated from the fixing groove and enter the mounting hole, which is convenient for quickly disassembling the sleeve and the IoT alarm;

[0022] 3. In the present application, the slider is pressed against the inner wall of the mounting hole under the elastic force of the spring, so that the fixing block remains plugged into the fixing groove, reducing the probability of the fixing block being separated from the fixing groove due to the movement of the slider, thereby reducing the probability of the sleeve and the IoT alarm falling off.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0028] like Figure 1-3 As shown, an embodiment of the present application discloses an Internet of Things fire alarm, including a fixing plate 1, a mounting seat 2, a sleeve 3, an Internet of Things alarm 4, a fixing block 5 and a moving component 6.

[0029] The fixing plate 1 is a circular plate-shaped structure, and the fixing plate 1 is fixed on the wall. The mounting seat 2 is a round block-shaped structure, and the mounting seat 2 is fixed to the bottom of the fixing plate 1. The side wall of the mounting seat 2 is penetrated with a mounting hole 21. The sleeve 3 is a cylindrical structure with an opening at the top. The sleeve 3 is sleeved on the mounting seat 2 and plugged with the mounting seat 2. The inner wall of the sleeve 3 is provided with two fixing grooves 31 that match the mounting holes 21, and the intersection between the top of the sleeve 3 and the side wall of the sleeve 3 is provided with a plug hole 32. The Internet of Things alarm 4 is an Internet of Things alarm 4 commonly used in the prior art and suitable for the present embodiment, and the Internet of Things alarm 4 is arranged at the bottom of the sleeve 3. The fixing block 5 is a rectangular parallelepiped structure, and the fixing block 5 is slidably connected in the mounting hole 21. Two fixing blocks 5 are symmetrically arranged, and the two fixing blocks 5 are plugged with the two fixing grooves 31 respectively.

[0030] The moving assembly 6 is installed on the mounting seat 2 and is used to move the two fixed blocks 5. The moving assembly 6 includes a cross bar 61, a slider 62, a pulling block 63 and a connecting rod 64. The cross bar 61 is a horizontally arranged round rod-shaped structure. The cross bar 61 is penetrated and slidably connected to the side wall of the mounting seat 2. The cross bar 61 is slidably connected to the inner wall of the jack 32. The slider 62 is a rectangular parallelepiped structure. The slider 62 is slidably connected to the inner wall of the mounting hole 21. The slider 62 is fixed to the end of the cross bar 61. The pulling block 63 is a round block-shaped structure. The pulling block 63 is fixed to the end of the cross bar 61 away from the slider 62. The connecting rod 64 is a rectangular rod-shaped structure. The connecting rod 64 is rotatably connected to the side wall of the slider 62. Two connecting rods 64 are provided and symmetrically arranged on the side walls on both sides of the slider 62. The ends of the two connecting rods 64 away from the slider 62 are rotatably connected to the side walls of the two fixed blocks 5 respectively.

[0031] The two fixing blocks 5 are respectively inserted into the two fixing grooves 31, so as to fix the sleeve 3 and the Internet of Things alarm 4 on the mounting base 2. When the Internet of Things alarm 4 needs to be disassembled, the staff only needs to pull the cross bar 61 and the slider 62 outward through the pulling block 63. Since the slider 62 is rotatably connected to the connecting rod 64, the connecting rod 64 is rotatably connected to the fixing block 5, and the fixing block 5 is slidably connected to the inner wall of the mounting hole 21, the two connecting rods 64 pull the two fixing blocks 5 to move closer to each other, so that the two fixing blocks 5 are disengaged from the fixing grooves 31 and enter the mounting hole 21, thereby removing the sleeve 3 and the Internet of Things alarm 4, eliminating the tedious operation of disassembling through multiple bolts, and facilitating the maintenance and repair of the Internet of Things alarm 4.

[0032] In order to reduce the probability of the sleeve 3 and the Internet of Things alarm 4 falling off, a spring 7 is arranged in the mounting hole 21, and the spring 7 is sleeved on the cross bar 61. One end of the spring 7 is fixed to the inner wall of the mounting hole 21, and the other end of the spring 7 is fixed to the side wall of the slider 62. The slider 62 is pressed against the inner wall of the mounting hole 21 under the elastic force of the spring 7, so that the fixing block 5 maintains the plug-in state of the fixing groove 31, reducing the probability of the fixing block 5 being separated from the fixing groove 31 due to the movement of the slider 62, thereby reducing the probability of the sleeve 3 and the Internet of Things alarm 4 falling off.

[0033] In order to enhance the fixing effect of the fixing block 5 on the sleeve 3, a rubber pad 8 is fixed to the inner wall of each fixing groove 31. The rubber pad 8 is made of rubber material and its surface has a large friction coefficient. The fixing block 5 cooperates with the fixing groove 31 and presses against the rubber pad 8, thereby increasing the friction between the fixing block 5 and the fixing groove 31, thereby enhancing the fixing effect of the fixing block 5 on the sleeve 3.

[0034] In order to facilitate the alignment and insertion of the fixing block 5 with the fixing groove 31, a chamfer 51 is provided on the side wall of each fixing block 5 away from the connecting rod 64. The setting of the chamfer 51 reduces the difficulty of aligning the fixing block 5 with the fixing groove 31, thereby facilitating the alignment and insertion of the fixing block 5 with the fixing groove 31.

[0035] In order to reduce the probability of the sleeve 3 and the Internet of Things alarm 4 accidentally falling, an upper magnetic block 9 is embedded in the bottom of the mounting base 2, and a lower magnetic block 10 magnetically attracted to the upper magnetic block 9 is embedded in the inner bottom wall of the sleeve 3. When the sleeve 3 and the Internet of Things alarm 4 are disassembled, after the fixing block 5 is separated from the fixing groove 31, the sleeve 3 is still adsorbed on the mounting base 2, thereby reducing the probability of the sleeve 3 and the Internet of Things alarm 4 accidentally falling and enhancing the stability of the Internet of Things alarm 4.

[0036] In order to reduce the wear between the top of the sleeve 3 and the bottom of the fixed plate 1, an annular rubber sheet 11 is fixed to the bottom of the fixed plate 1. The annular rubber sheet 11 is sleeved on the mounting seat 2. The annular rubber sheet 11 is made of rubber material, and the material is elastic. The top of the sleeve 3 cooperates with the bottom of the fixed plate 1 and presses against the annular rubber sheet 11, thereby reducing the wear between the top of the sleeve 3 and the bottom of the fixed plate 1.

[0037] The use principle of an Internet of Things fire alarm in the present embodiment is as follows: the two fixing blocks 5 are respectively inserted into the two fixing grooves 31, so that the sleeve 3 and the Internet of Things alarm 4 are fixed on the mounting seat 2. When the Internet of Things alarm 4 needs to be disassembled, the staff only needs to pull the cross bar 61 and the slider 62 outward through the pulling block 63. Since the slider 62 is rotatably connected to the connecting rod 64, the connecting rod 64 is rotatably connected to the fixing block 5, and the fixing block 5 is slidably connected to the inner wall of the mounting hole 21, the two connecting rods 64 pull the two fixing blocks 5 to move closer to each other, so that the two fixing blocks 5 are disengaged from the fixing grooves 31 and enter the mounting hole 21, thereby removing the sleeve 3 and the Internet of Things alarm 4, eliminating the tedious operation of disassembling through multiple bolts, and facilitating the maintenance and repair of the Internet of Things alarm 4.

[0038] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
