[0031] It should be further pointed out that the installation position of the turning shaft 104 and the heat protection rod 102 is provided with a torsional spring.

[0032] Further, one side of the middle heat protection rod 102 is provided with a rotating groove 111 opening outward, a rotating shaft 112 is rotatably arranged in the rotating groove 111, and a hand holding disc 113 is installed at the front end of the rotating shaft 112.

[0033] It should be further pointed out that, as shown in Figure 6 and Figure 7 , the hand holding disc 113 is in a horizontal state in normal state, which can play a role of abutting and limiting movement of the protection plate 109, when the hand holding disc 113 is rotated to a vertical state, the protection plates 109 on both sides lose the abutting and limiting movement of the hand holding disc 113, at this time, the turning shaft 104 loses the limiting position and rotates to reset under the action of the torsional spring, at this time, the turning shaft 104 resets and rotates to drive the protection plates 109 on both sides to rotate and open, forming an arc-shaped protection baffle area.

[0034] Further, the bottom of the fire extinguisher bottle 101 is provided with an outwardly opening expansion cavity 128, an expansion rotating ring 114 is rotatably arranged in the expansion cavity 128, a lifting and lowering movable expansion bottom plate 117 is threadedly connected in the expansion rotating ring 114, and a window breaker 116 is fixedly arranged at the bottom center position of the expansion bottom plate 117.

[0035] It should be further pointed out that the window breaker 116 is made of high carbon steel material, which is convenient for breaking the window and escaping in emergency.

[0036] Further, the expansion rotating ring 114 is fixedly connected with a hand holding rotating rod 115 on one side of the end face for convenient hand holding.

[0037] It is worth mentioning that when the hand-held rotating rod 115 is rotated and the telescopic rotating ring 114 is rotated, the telescopic bottom plate 117 can be driven to move outward through the threaded connection, and in turn the window breaker 116 is driven to extend outward.

[0038] Further, the fire extinguisher bottle 101 is provided with a fire extinguisher liner 118, and the top end of the fire extinguisher liner 118 is provided with a semicircular arc-shaped detection cavity 119. The detection cavity 119 is fixedly provided with a gas pressure detector 120 at one side.

[0039] It needs to be further explained that the gas pressure detector 120 can detect the gas pressure value in the fire extinguisher liner 118. The inside of the fire extinguisher liner 118 adopts a non-pressure storage method, such as dry powder or gas generating agent, which is activated only when in use, to avoid safety hazards during transportation and storage.

[0040] Further, the fire extinguisher liner 118 is provided with a pressure release valve 127 at the top end of one side and below the gas pressure detector 120, and the opening of the pressure release valve 127 is in communication with the outside.

[0041] It needs to be further explained that the pressure release valve 127 is controlled and connected through the gas pressure detector 120. When the gas pressure detector 120 detects that the gas pressure in the fire extinguisher liner 118 increases due to the temperature of the outside space, the pressure release valve 127 can be controlled by the gas pressure detector 120 to release the gas pressure in the fire extinguisher liner 118 to prevent explosion.

[0042] Further, a communication pipeline 121 is provided between the top end of the detection cavity 119 and the fire extinguisher nozzle 107, and the communication pipeline 121 penetrates the rotating bottom plate 105 and communicates with the fire extinguisher nozzle 107.

[0043] Further, the rotating bottom plate 105 is installed and connected with the communication pipeline 121 at the lower end surface, and a semicircular arc-shaped closure plug 122 is installed in the communication pipeline 121.

[0044] It is worth further mentioning that when the closure plug 122 is rotated to above the gas pressure detector 120, the detection cavity 119 is in communication with the communication pipeline 121, and when the closure plug 122 is rotated to the other side, the top end of the detection cavity 119 is closed by the closure plug 122, which has the effect of disconnecting the communication.

[0045] It needs to be further explained that the communication pipeline 121 is provided with a gas generating agent in the hollow slot. When the communication pipeline 121 is rotated and communicated with the detection cavity 119, the gas generating agent falls downward into the fire extinguisher liner 118 through the detection cavity 119, and in turn produces high-pressure gas to achieve the working state of extinguishing fire.

[0046] Further, the top end of the closing plate 108 is provided with an outwardly open turnover clamping groove 123, and a limiting shaft 124 is rotatably arranged in the turnover clamping groove 123.

[0047] Further, the two side end faces of the rotating disc 105 are provided with two outwardly open limiting grooves 126, and the two limiting grooves 126 are symmetrically arranged.

[0048] It needs to be further explained that when the limiting clamping plate 125 is rotated to the vertical state, it can be clamped into the limiting groove 126 and play a limiting rotating effect.

[0049] When the present scheme is used, the user can move the fire extinguisher bottle 101 as a whole to the working position, and first disconnect the clamping buckle of the limiting clamping plate 125 and the limiting groove 126 when in use, at this time the limiting clamping plate 125 is turned downward, at this time the rotation limitation of the rotating disc 105 is opened, the user holds the rotating disc 105 and rotates, so that the closing plug 122 is rotated above the gas pressure detector 120, at this time the communication pipeline 121 is communicated with the detection cavity 119, the gas generating agent falls into the fire extinguisher inner container 118 through the detection cavity 119, and then produces high-pressure gas to achieve the fire extinguishing working state, at this time the worker can realize the injection of the fire extinguishing agent by controlling the fire extinguisher switch 106 to achieve fire extinguishing.

[0050] When encountering a larger fire, the gas pressure detector 120 detects that the gas pressure in the fire extinguisher inner container 118 increases due to the temperature of the external space, and can control the pressure release valve 127 to release the gas pressure in the fire extinguisher inner container 118 to prevent explosion.

[0051] When encountering a serious situation, the hand-held disc 113 is rotated to the vertical state, at this time the two side protection plates 109 lose the abutting and limiting movement of the hand-held disc 113, at this time the turnover shaft 104 loses the limiting movement and is reset under the action of the torsional spring force, at this time the turnover shaft 104 is reset and rotated, and can drive the two side protection plates 109 to rotate and open, forming an arc-shaped protection baffle area, at this time the worker holds the fire extinguisher bottle 101 as a whole through the hand-held disc 113, and implements the fire extinguishing rescue work under the protection of the protection plate 109, thereby improving the safety of the fire extinguishing personnel.

[0052] When the staff needs to break the window to escape in the fire scene, the staff first opens the protection board 109 to form protection, and holds the rotating rod 115 and rotates the telescopic rotating ring 114, at this time the telescopic rotating ring 114 rotates to drive the telescopic bottom plate 117 to move outward through the threaded connection, and further drives the window breaker 116 to extend outward, at this time the staff can hold the disc 113 and lift the fire extinguisher bottle 101 to implement the impact breaking window work of the window breaker 116, and through the opened protection board 109, the broken glass debris is prevented from causing harm to the personnel, and the safety of personnel escape is further improved.

[0053] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
