DETAILED DESCRIPTION

[0030] The embodiment of the present invention provides a multifunctional non-pressure fire extinguisher for anti-violence and self-rescue, such as Figure 1-7As shown, it includes a fire extinguisher bottle 101, a rotating chassis 105, a closing plate 108 and a fire extinguisher nozzle 107. The closing plate 108 is fixedly arranged at the top of the fire extinguisher bottle 101, the rotating chassis 105 is rotatably arranged at the upper end of the closing plate 108, the fire extinguisher nozzle 107 is installed at the top of the rotating chassis 105, and the tail end of the fire extinguisher nozzle 107 is provided with a fire extinguisher switch 106 for controlling the switch of the fire extinguisher nozzle 107. The outer end surface of the fire extinguisher bottle 101 is provided with a plurality of annular heat insulation protection rods 102. The heat insulation protection rod 102 is provided with a plurality of annular heat insulation protection rods 102. The 02 position is arranged in an array from top to bottom, and a plurality of supporting connecting rods 103 are installed on the heat-insulating protection rods 102 on each side. The supporting connecting rods 103 are distributed along a semicircular array. A circular support chassis 110 is installed and connected under the bottom heat-insulating protection rod 102. Four flip shafts 104 are arranged on one side for rotation between the upper and lower heat-insulating protection rods 102. Two flip shafts 104 are distributed on both sides of the fire extinguisher bottle 101 as a group, and a circular arc fan-shaped protective plate 109 is installed between the flip shafts 104 on both sides in the vertical direction.

[0031] It should be further explained that a torsion spring is provided at the installation position of the flip shaft 104 and the heat insulation protection rod 102 .

[0032] Furthermore, a rotating groove 111 opening outward is provided on one side of the heat insulation protection rod 102 on the middle side, a rotating shaft 112 is rotatably provided in the rotating groove 111, and a hand-held disk 113 is installed at the front end of the rotating shaft 112. The hand-held disk 113 can abut the rear ends of the protective plates 109 on both sides to limit the rotation.

[0033] It is worth further explaining that Figure 6 and Figure 7 As shown, the hand-held disk 113 is in a horizontal state under normal circumstances and can play the role of abutting and limiting the movement of the protective plate 109. When the hand-held disk 113 is rotated to a vertical state, the protective plates 109 on both sides lose the abutting and limiting movement of the hand-held disk 113. At this time, the flip shaft 104 that loses the limit rotates and resets under the action of the torsion spring elastic force. At this time, the flip shaft 104 resets and rotates, and can drive the protective plates 109 on both sides to rotate and open, forming an arc-shaped protective baffle area.

[0034] Furthermore, a telescopic cavity 128 opening outward is provided at the bottom of the fire extinguisher bottle 101, a telescopic swivel 114 is rotatably provided in the telescopic cavity 128, the telescopic swivel 114 is threadedly connected to a telescopic bottom plate 117 that can be raised and lowered, and a window breaker 116 is fixedly provided at the bottom center of the telescopic bottom plate 117.

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

[0036] Furthermore, a hand-held rotating rod 115 is fixedly connected to one end surface of the telescopic rotating ring 114 for easy hand-holding.

[0037] It is worth noting that when the rotating rod 115 is held and the telescopic rotating ring 114 is rotated, the rotation of the telescopic rotating ring 114 can drive the telescopic bottom plate 117 to move outward through the threaded connection, thereby driving the window breaker 116 to extend outward.

[0038] Furthermore, a fire extinguisher liner 118 is provided in the fire extinguisher bottle 101 , a semicircular arc-shaped detection cavity 119 is provided at the top of the fire extinguisher liner 118 , and an air pressure detector 120 is fixedly provided at a half position of the detection cavity 119 .

[0039] It should be further explained that the air pressure detector 120 can detect the air pressure value inside the fire extinguisher inner shell 118. The fire extinguisher inner shell 118 adopts a non-pressure storage method, such as dry powder or gas generating agent is only activated when used, avoiding safety hazards during transportation and storage.

[0040] Furthermore, a pressure relief valve 127 is installed on one side of the top end of the fire extinguisher inner shell 118 and below the air pressure detector 120, and the opening of the pressure relief valve 127 is connected to the outside.

[0041] It should be further explained that the pressure release valve 127 is controlled by the air pressure detector 120. When the air pressure detector 120 detects the air pressure in the fire extinguisher inner tank 118, and the internal air pressure increases due to the temperature of the external space, the air pressure detector 120 can control the pressure release valve 127 to start releasing the air pressure in the fire extinguisher inner tank 118 to prevent explosion.

[0042] Furthermore, a communication pipe 121 is provided between the top of the detection cavity 119 and the fire extinguisher nozzle 107 , and the communication pipe 121 passes through the rotating chassis 105 and is communicated with the fire extinguisher nozzle 107 .

[0043] Furthermore, the lower end surface of the rotating chassis 105 is connected to the communication pipe 121 , and a semicircular arc-shaped closing plug 122 is installed in the communication pipe 121 .

[0044] It is worth further explaining that when the closing plug 122 rotates to above the air pressure detector 120, the detection cavity 119 is connected to the connecting pipe 121. When the closing plug 122 is driven to rotate to the other side, the top of the detection cavity 119 is closed by the closing plug 122, thereby achieving the effect of disconnecting the connection.

[0045] It should be further explained that a gas generator is installed in the empty groove of the connecting pipe 121. When the connecting pipe 121 is rotated and connected to the detection chamber 119, the gas generator falls downward into the fire extinguisher inner tank 118 through the detection chamber 119, and then achieves the fire extinguishing working state by producing high-pressure gas.

[0046] Furthermore, a flip card slot 123 opening outward is provided on one side of the top end of the closing plate 108 , a limit shaft 124 is rotatably provided in the flip card slot 123 , and a limit card plate 125 is fixedly connected to the outer end surface of the limit shaft 124 .

[0047] Furthermore, two outwardly opening limiting grooves 126 are provided on both side end surfaces of the rotating chassis 105 , and the limiting grooves 126 on both sides are symmetrically arranged.

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

[0049] When using this solution, the user can hold the fire extinguisher bottle 101 and move it as a whole to the working position. When using it, the user first disconnects the limit card plate 125 and the limit groove 126. At this time, the limit card plate 125 flips downward, and the rotation limit of the rotating chassis 105 is opened. The user holds the rotating chassis 105 and rotates it to rotate the closing plug 122 to the top of the air pressure detector 120. At this time, the connecting pipe 121 is connected to the detection chamber 119, and the gas generating agent falls downward through the detection chamber 119 into the fire extinguisher inner tank 118, and then achieves the working state of fire extinguishing by producing high-pressure gas. At this time, the staff can realize the spraying of fire extinguishing agent to extinguish the fire by controlling the fire extinguisher switch 106.

[0050] When encountering a large fire, the air pressure detector 120 detects that the air pressure in the fire extinguisher inner tank 118 increases due to the temperature of the external space. The air pressure detector 120 can control the pressure release valve 127 to start releasing the air pressure in the fire extinguisher inner tank 118 to prevent explosion.

[0051] When encountering a serious situation, the hand-held plate 113 is rotated to a vertical state. At this time, the protective plates 109 on both sides lose the abutment and limiting movement of the hand-held plate 113. At this time, the flip shaft 104 that loses the limit rotates and resets under the action of the torsion spring elastic force. At this time, the flip shaft 104 resets and rotates, and then can drive the protective plates 109 on both sides to rotate and open, forming an arc-shaped protective baffle area. At this time, the staff can conveniently hold the fire extinguisher bottle 101 as a whole through the hand-held plate 113, and carry out fire-fighting and rescue work under the protection of the protective plates 109, thereby improving the safety of the fire-fighting personnel.

[0052] When the staff needs to break the window to escape at the fire scene, the staff first opens the protective plate 109 for protection, and at the same time holds the rotating rod 115 and rotates the telescopic rotating ring 114. At this time, the rotation of the telescopic rotating ring 114 can drive the telescopic bottom plate 117 to move outward through the threaded connection, and then drive the window breaker 116 to extend outward. At this time, the staff can hold the plate 113 and lift the fire extinguisher bottle 101 to implement the window breaker 116 to impact and break the window, and use the opened protective plate 109 to prevent the broken glass fragments from causing harm to personnel, thereby further improving the safety of personnel escape.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
