[0036] As Figures 1 to 5 , the present utility model provides an automatic alarm fire extinguisher box, including:

[0037] A fire extinguisher box body 1, inside which a support plate 120 is horizontally arranged, and at least one placement groove for placing a fire extinguisher is arranged on the support plate 120;

[0038] Travel switch, at least one is provided, and the travel switch is a single-roller automatic reset travel switch. The travel switch is arranged in the placement groove. The specific arrangement method is as follows: A through hole 8 penetrating the bottom surface of the placement groove and a long strip-shaped groove 7 communicating with the through hole 8 are provided on the bottom surface of the placement groove. The swing arm of the travel switch passes through the through hole and is located above the placement groove. The two normally open terminals, two normally closed terminals and the connecting piece of the travel switch are located below the placement groove. One normally closed terminal is connected to the power supply 3, and the other normally closed terminal is electrically connected to an alarm 4. The power supply 3, the two normally closed terminals, the connecting piece and the alarm 4 form a loop;

[0039] Guide rod 9, at least one is provided and corresponds to the travel switch one by one. One end of the guide rod 9 is hinged to the inner wall of one side of the fire extinguisher box body 1, and the other end crosses the swing arm and hangs above the placement groove. A torsion spring 10 is arranged between one end of the guide rod and the inner wall of the fire extinguisher box body; wherein,

[0040] The guide rod 9 is arranged to be able to contact the outer wall of the fire extinguisher and be driven to rotate towards the side close to the swing arm by it;

[0041] The swing arm is arranged to be driven to rotate by the guide rod 9, so that the swing arm can rotate into the long strip-shaped groove 7 under the pressing action of the fire extinguisher, so as to drive the connecting piece to be connected with the two normally open terminals, and reset when the pressing force of the fire extinguisher disappears, so as to drive the connecting piece to be connected with the two normally closed terminals.

[0042] Among them, when the fire extinguisher presses the swing arm of the travel switch, the two normally closed terminals and the connecting piece are disconnected, and the alarm 4 is not powered on. When the fire extinguisher is picked up from the placement groove, after the swing arm of the travel switch resets and leaves the long strip-shaped groove 7, the two normally closed terminals and the connecting piece are connected, and the alarm 4 is powered on and gives an alarm.

[0043] In the above embodiment, such as Figures 1 to 4As shown, two placement slots are provided in the fire extinguisher box body 1, including a first fire extinguisher placement slot 100 and a second fire extinguisher placement slot 110. Through holes 8 and elongated grooves 7 are provided in each placement slot. A first travel switch 2 is provided in the first fire extinguisher placement slot 100, and a second travel switch 5 is provided in the second fire extinguisher placement slot 110. The first travel switch 2 and the second travel switch 5 have the same structure. Taking the first travel switch 2 as an example, it includes a circuit component 200 and a swing arm 210. The swing arm 210 passes through the through hole 8 and is located above the first fire extinguisher placement slot 100, and the circuit component 200 is located below the first fire extinguisher placement slot. The swing arm 210 can rotate around the circuit component 200. The circuit component 200 includes two normally open terminals, two normally closed terminals, and a connecting piece. One normally closed terminal is connected to the power supply 3, and the other normally closed terminal is electrically connected to an alarm 4, so that the power supply 3, the two normally closed terminals, the connecting piece, and the alarm 4 form a loop; the two normally closed terminals, the connecting piece in the second travel switch 5, and the power supply 3 and the alarm 4 form another loop. The loops formed by the first travel switch 2 and the second travel switch 5 are parallel loops. In this way, as long as any fire extinguisher is taken away from the first fire extinguisher placement slot 100 and the second fire extinguisher placement slot 110, an alarm will be triggered, and they do not affect each other. As Figure 3 and Figure 4 shown, the specific alarm working principle is as follows: When a fire extinguisher is placed in the first fire extinguisher placement slot 100, the placed fire extinguisher drives the guide rod 9 to rotate clockwise toward the side close to the swing arm 210, and the torsion spring 10 stores energy. The guide rod 9 contacts the swing arm 210 and drives the swing arm 210 to rotate counterclockwise to an inclined state. The fire extinguisher continues to be placed, and the swing arm 210 is pressed into the elongated groove 7 under the pressing action of the fire extinguisher, presenting a state as shown in Figure 3 shown. At this time, the swing arm 210 drives the connecting piece to connect with the two normally open terminals. At this time, the two normally closed terminals and the connecting piece are disconnected. The loop formed by the two normally closed terminals, the connecting piece, the power supply 3, and the alarm 4 in the first travel switch 2 is in an open state, and the alarm is not powered on and does not alarm; when the fire extinguisher placed in the first fire extinguisher placement slot 100 is picked up, the guide rod 9 is reset under the action of the torsion spring 10, the swing arm 210 in the first travel switch 2 is reset, and the swing arm 210 of the first travel switch 2 leaves the elongated groove 7, presenting a state as shown in Figure 4 shown. At this time, the swing arm 210 drives the connecting piece to connect with the two normally closed terminals. At this time, the two normally closed terminals and the connecting piece are connected. The loop formed by the two normally closed terminals, the connecting piece, the power supply 3, and the alarm 4 in the first travel switch 2 is in a connected state, and the alarm is powered on and alarms. The alarm principle of the loop formed by the two normally closed terminals, the connecting piece in the second travel switch 5, and the power supply 3 and the alarm 4 is the same as that of the first travel switch 2.

[0044] Among them, the travel switch is a single-roller automatic reset travel switch, and the model is LX19-111 (AC380V, DC220V, 5A). When using the single-roller automatic reset travel switch, when the fire extinguisher is pressed down by 0, the lowered fire extinguisher drives the guide rod 9 to rotate clockwise towards the side close to the swing arm 210, and the torsion spring 10 stores energy. The guide rod 9 contacts the swing arm 210 and drives the swing arm 210 to rotate counterclockwise to an inclined state. When the fire extinguisher is further lowered, the swing arm 210 rotates counterclockwise around its fixed fulcrum connected to the circuit component. The swing arm 210 is pressed into the long strip-shaped groove 7 under the pressing action of the fire extinguisher. The roller in the circuit component rolls to the right. At this time, the spring in the circuit component is compressed to store energy, driving the connecting piece to connect two normally open terminals. When the fire extinguisher is picked up, the spring resets, driving the connecting piece to connect two normally closed terminals, the circuit is powered on, and the alarm sounds.

[0045] In another embodiment, the fire extinguisher box for automatic alarm further includes:

[0046] A lifting mechanism 6, which is arranged inside the fire extinguisher box body 1, and the support plate 120 is arranged on the lifting mechanism 6.

[0047] In the above embodiment, by arranging the placement groove for the fire extinguisher on the lifting mechanism 6 to lift the fire extinguisher, when there is a fire and the fire extinguisher is urgently needed, the lifting mechanism 6 can be immediately lifted to drive the fire extinguisher to a suitable height, without having to squat down to unlock or bend down and reach into the fire extinguisher box to pick it up, which is convenient for picking up and saves time for fire extinguishing work, improving the fire extinguishing efficiency.

[0048] In another embodiment, as Figure 5 shown, the lifting mechanism 6 includes:

[0049] A top plate 600, which serves as the top cover of the fire extinguisher box for automatic alarm;

[0050] A bottom plate 610, which is arranged below the support plate 120. The two sides of the bottom plate 610, the support plate 120 and the top plate 600 are connected by a pair of columns 620, and a jacking part 621 is arranged on each column;

[0051] A pair of lifting members 630, which are correspondingly arranged below the jacking part 621.

[0052] In the above embodiment, as Figure 5As shown in the figure, a first fire extinguisher placement groove 100 and a second fire extinguisher placement groove 110 are provided on the support plate 120. The top plate 600 is adapted to the upper opening of the fire extinguisher box body 1 and can be used as the top cover of the fire extinguisher box body 1. The top plate 600, the support plate 120, and the bottom plate 610 are connected by the column 620 to form an integral structure. A jacking portion 621 is provided on the column 620. A circular embedding groove is provided at the bottom of the jacking portion 621. The top end of the lifting member 630 is a cylindrical structure adapted to the circular embedding groove, and it is embedded into the circular embedding groove, so that when the lifting member 630 lifts and lowers, it drives the bottom plate 610, the support plate 120, and the fire extinguisher thereon to lift and lower smoothly, as Figure 1 shown. When the lifting mechanism 6 is not lifted or lowered, the bottom of the lifting member 630 contacts the inner bottom of the fire extinguisher box body 1, so that when the lifting mechanism 6 is not lifted or lowered, the entire lifting mechanism 6 is stably placed in the fire extinguisher box body 1. At this time, the top plate 600 covers the fire extinguisher box body 1 tightly, making the fire extinguisher box in a closed state. When it is necessary to lift, the lifting member 630 lifts and lowers to jack up the jacking portion 621, and then drives the bottom plate 610, the support plate 120, and the top plate 600 to rise to an appropriate height. At this time, the user can quickly take out the fire extinguisher in the fire extinguisher box for use, which is convenient and fast, and improves the efficiency of using the fire extinguisher to extinguish the fire. In this implementation scheme, the number of the guide rods 9 is 2. The two guide rods 9 are respectively arranged on the column 620. One end of the guide rod 9 is hinged to the column 620, and the other end extends over the swing arm and hangs above the placement groove. A torsion spring 10 is arranged between the other end of the guide rod 9 and the column 620.

[0053] In another implementation scheme, the lifting member 630 is a hydraulic cylinder. The bottom of the hydraulic cylinder is a horizontal structure. A multi-stage telescopic rod is provided in the hydraulic cylinder. The top of the multi-stage telescopic rod is a cylindrical structure. An embedding groove matching the cylindrical structure is provided at the bottom of the jacking portion 621. The cylindrical structure is embedded into the embedding groove. The hydraulic cylinder is communicatively connected to the fire control console. In this implementation scheme, the cylindrical structure is embedded into the embedding groove, and then drives the jacking portion 621 to lift and lower. The bottom plate 610 and the top plate 600 follow to lift and lower to realize the lifting and lowering of the fire extinguisher placed on the bottom plate 610. Among them, the hydraulic cylinder is a hydraulic cylinder on the existing market, and its model is not limited as long as the structure can meet the above requirements and realize the above functions. The cylindrical structure is a cylindrical block structure, and the inside of the embedding groove is also cylindrical. The cross-sectional diameter of the block structure is slightly smaller than the cross-sectional diameter inside the embedding groove, and the depth of the embedding groove is equal to the height of the block structure, so that the block structure is just embedded into the embedding groove. The hydraulic cylinder is communicatively connected to the fire control console, so that when the fire control console receives a fire alarm signal, it controls the hydraulic cylinder to start and quickly lift the fire extinguisher, so that the user can quickly get the fire extinguisher and improve the fire extinguishing efficiency.

[0054] In another embodiment, the power supply 3 and the alarm 4 are arranged outside the side wall of the fire extinguisher box body 1. By arranging the power supply 3 and the alarm 4 on the outer surface of the vertical side plate of the fire extinguisher box body 1, the circuit formed by the power supply 3 and the alarm 4 is not affected when the lifting mechanism 6 is lifted and lowered.

[0055] In another embodiment, the alarm 4 is communicatively connected to a fire control console. By communicatively connecting the alarm 4 to a remote fire control console, when the fire control console receives the alarm signal from the alarm 4, it can immediately arrange for fire inspection personnel to check on the spot, promptly restore the position of the fire extinguisher, and prevent it from being misappropriated or lost, so as not to delay fire extinguishing.

[0056] Although the embodiments of the present utility model have been disclosed as above, it is not limited to only the applications listed in the description and embodiments. It can be fully applied to various fields suitable for the present utility model. For those familiar with the field, additional modifications can be easily achieved.
