Description

Technical Field

[0001] The utility model is applicable to the technical field of fire alarm controllers, and particularly relates to a fire alarm controller with safety protection. Background Art

[0002] At present, the fire alarm controller is the heart of the automatic fire alarm system and can supply power to the detector. The fire alarm controller can be divided into regional type, centralized type and control center alarm system according to the monitoring area. The regional alarm controller is an automatic working device responsible for fire monitoring in an alarm area. An alarm area includes many detection areas.

[0003] However, nowadays, when fire alarms are placed for use, they are often placed on the wall for a long time to warn and monitor the smoke and fire in the indoor environment. Since there is no corresponding protective mechanism on the outside of the fire alarm during daily placement, it is very easy for pedestrians indoors to contact the outer side during movement, causing collision damage to it, affecting its normal use. Therefore, we propose a fire alarm controller with safety protection. Utility Model Content

[0004] The main purpose of the utility model is to provide a fire alarm controller with safety protection, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A fire alarm controller with safety protection, comprising an alarm housing, both ends of the side surface of the alarm housing are fixedly mounted with connection blocks, and the number of the connection blocks is four groups, each of the outer surfaces of the connection blocks is fixedly mounted with a fixed pipe clamp, and a hollow pipe is fixedly sleeved between the inner sides of each two groups of the fixed pipe clamps;

[0007] Movable rods are movably installed on both sides of the hollow tube, a transmission arc plate is fixedly installed between each two groups of the movable rods away from the side of the hollow tube, an extrusion plate is fixedly installed on the surface of one end of each movable rod close to the hollow tube, and the extrusion plate is movably installed inside the hollow tube, a buffer spring is movably sleeved inside the middle end of each hollow tube, and the side of the buffer spring is movably fitted to the outer side of the extrusion plate.

[0008] By adopting the above technical solution, the impact force borne by the surface of the transmission arc plate is buffered under the transmission action of the movable rod and the buffering action of the buffer spring, thereby preventing the impact force from directly contacting and acting on the outside of the alarm casing and causing damage thereto, thereby achieving protective treatment of the outside of the alarm casing.

[0009] As an optional solution of the technical solution of the present application, movable grooves are provided inside the two ends of the outer side of each of the hollow tubes, and movable rods are slidably installed inside the movable grooves.

[0010] By adopting the above technical solution, the transmission rationality of the entire device is ensured by the guiding sliding action of the movable groove on the movable rod.

[0011] As an optional solution of the technical solution of the present application, a guide block is fixedly installed on the outer surface of each extrusion plate, a guide groove is opened inside each hollow tube, and the guide block is slidably inserted into the guide groove.

[0012] By adopting the above technical solution, the transmission stability of the entire device is ensured by the guiding sliding action of the guide groove on the guide block.

[0013] As an optional solution of the technical solution of the present application, a buffer pad is fixedly bonded to the outer surface of each transmission arc plate, a damping pad sleeve is fixedly sleeved on the outer surface of each extrusion plate, and the outer side of the damping pad sleeve is fitted to the inner wall of the hollow tube.

[0014] By adopting the above technical solution, the stability of the entire device when restoring its position is ensured by the contact damping action of the damping cushion sleeve.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. A fire alarm controller with safety protection in the technical solution of the present application connects a transmission arc plate and an extrusion plate located inside a hollow tube through a movable rod, so that when the external impact force contacts the outer side of the transmission arc plate and causes it to move toward the outside of the alarm casing, it can drive the extrusion plate to move horizontally inside the hollow tube synchronously, causing the buffer spring located inside the hollow tube to be squeezed and deformed, so that the buffer spring buffers the impact force on the surface of the transmission arc plate during the deformation process, thereby preventing the impact force from directly contacting and acting on the outside of the alarm casing and causing damage to it, thereby achieving protective treatment of the outside of the alarm casing.

[0017] 2. A fire alarm controller with safety protection in the technical solution of the present application, by slidingly inserting the guide block into the guide groove, combined with the guiding sliding action of the guide groove on the guide block, can make the extrusion plate only move horizontally inside the hollow tube when pushed, thereby ensuring the rationality of the extrusion transmission of the buffer spring.

[0022] like Figure 1-3 As shown, the utility model provides a technical solution: a fire alarm controller with safety protection, wherein movable grooves 3 are provided inside the two ends of the outer side of each hollow tube 2, and a movable rod 21 penetrates and is slidably installed inside the movable groove 3.

[0023] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a guide block 32 is fixedly installed on the outer surface of each extrusion plate 22, and a guide groove 31 is opened inside each hollow tube 2. The number of guide grooves 31 and guide blocks 32 is four groups, and the guide blocks 32 are slidably inserted into the guide grooves 31.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), connecting blocks 11 are fixedly installed on the surfaces of both ends of the side of the alarm housing 1, and the number of connecting blocks 11 is four groups, and a fixed pipe clamp 12 is fixedly installed on the outer surface of each connecting block 11, and a hollow tube 2 is fixedly sleeved between the inner sides of every two groups of fixed pipe clamps 12.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), movable rods 21 are movably installed on both sides of the hollow tube 2, and a transmission arc plate 25 is fixedly installed between each two groups of movable rods 21 away from the side of the hollow tube 2, and an extrusion plate 22 is fixedly installed on the surface of one end of each movable rod 21 close to the hollow tube 2, and the extrusion plate 22 is movably installed inside the hollow tube 2, and a buffer spring 24 is movably sleeved inside the middle end of each hollow tube 2, and the side of the buffer spring 24 is movably fitted to the outside of the extrusion plate 22, and a buffer pad 26 is fixedly bonded to the outer surface of each transmission arc plate 25.

[0027] During operation, after the alarm housing 1 is installed on the indoor wall to be used, after the external contact impact force acts on the outer side of the transmission arc plate 25, causing it to move toward the outside of the alarm housing 1, under the transmission action of the movable rod 21, and the guiding sliding action of the guide groove 31 on the guide block 32, and synchronously under the guiding sliding action of the movable groove 3 on the movable rod 21, the extrusion plate 22 can only move horizontally inside the hollow tube 2 synchronously, causing the buffer spring 24 located inside the hollow tube 2 to be squeezed and deformed, so that the buffer spring 24 buffers the impact force on the surface of the transmission arc plate 25 during the deformation process, and under the action of the damping pad sleeve 23 on the outer side of the extrusion plate 22, the buffer spring 24 is prevented from recovering too quickly due to deformation, and damping protection treatment is performed.
