Description

Technical Field

[0001] This utility model relates to the technical field of dry powder fire extinguisher structure, specifically a modular dry powder fire extinguisher structure. Background Technology

[0002] Dry powder fire extinguishers are a type of fire extinguisher suitable for initial fires involving flammable and combustible liquids, gases, and electrical equipment. The dry powder used as the extinguishing agent inside a dry powder fire extinguisher is a dry and easily flowing fine solid powder. This powder is made by using inorganic salts with fire extinguishing properties as a base material, with the addition of small amounts of moisture-proofing agents, flow promoters, anti-caking agents, and other additives, and then drying, pulverizing, and mixing them. Dry powder fire extinguishers are mainly used to extinguish initial fires involving flammable liquids and combustible gases such as petroleum and organic solvents, and can also be used to extinguish general fires.

[0003] For example, patent document CN 216319638 U discloses a multifunctional modular fire extinguisher, including a base. A water-based fire extinguisher is placed at the top center of the base. Dry powder and carbon dioxide fire extinguishers are respectively slidably secured to both sides of the water-based fire extinguisher via locking components. A fire blanket is wrapped around both the dry powder and carbon dioxide fire extinguishers. A handle is fixed to one end of the fire blanket, with a positioning distress light embedded in one end and a buzzer alarm embedded in the other. An annular sleeve is slidably attached to the fire blanket, with its bottom frictionally engaged in an annular groove recessed at the top edge of the base. This modular fire extinguisher allows for free disassembly and assembly of different fire extinguishers, providing comprehensive fire extinguishing functions. By concentrating various fire rescue equipment in one place, it facilitates rapid use in emergencies and reduces safety hazards caused by fires.

[0004] However, due to its inherent structural limitations, this structure cannot be used for the rapid modular assembly and use of dry powder fire extinguishers. In actual use, it cannot be used for the rapid switching of the dry powder canister of the dry powder fire extinguisher, and the equipment cannot perform the adaptation and limiting operation when using the dry powder fire extinguisher, thus failing to meet daily usage needs. Therefore, it is urgent to design a modular dry powder fire extinguisher structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a modular dry powder fire extinguisher structure to solve the problems mentioned in the background art. Due to the limitations of its own structure, the existing structure cannot perform modular rapid assembly and use of dry powder fire extinguishers in actual use. It also cannot perform rapid switching of the dry powder canister of the dry powder fire extinguisher in actual use. At the same time, the equipment cannot perform adaptation and limiting operation when using dry powder fire extinguishers, thus failing to meet the needs of daily use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular dry powder fire extinguisher structure, including a connection base, a control nozzle fixedly connected to the surface of the connection base, a safety bolt provided at the top of the control nozzle, a limiting back frame fixedly connected to the back of the control nozzle, and a spraying pressure bar provided inside the limiting back frame;

[0007] The tank body is provided at the bottom end of the connecting seat, and a limiting ring seat is sleeved on the outer surface of the tank body. A lifting handle is fixedly connected to the back of the limiting ring seat.

[0008] Preferably, the inner wall of the limiting ring seat is provided with a first sealing pad, and the side of the tank is provided with a second sealing pad.

[0009] Preferably, a support base is fixedly connected to the bottom end of the tank, and a screw-on seat is fixedly connected to the top end of the tank.

[0010] Preferably, a sealing ring is provided at the top of the screw-in seat, and a high-pressure valve is provided inside the screw-in seat.

[0011] Preferably, the side of the limiting back frame is provided with a movable groove, and the inner wall of the movable groove is provided with a movable frame.

[0012] Preferably, the movable frame has an internal movable connection of a limiting block, and one end of the limiting block is provided with a pull handle.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This modular dry powder fire extinguisher structure, through its connection base, control nozzle, safety bolt, limiting back frame, spray lever, tank body, support base, screw-in seat, sealing ring, and high-pressure valve, allows for the rapid replacement of multiple dry powder fire extinguisher tanks. In actual use, the operator first screws the tank to be used onto the bottom of the connection base using the screw-in seat and the top sealing ring, ensuring a tight seal. The high-pressure valve inside the screw-in seat connects to the control nozzle on the surface of the connection base. Then, the safety bolt on the control nozzle surface can be released, allowing direct activation of the dry powder fire extinguisher via the spray lever on the limiting back frame. This enables rapid modular assembly and use of the dry powder fire extinguisher, making it more adaptable to daily operations and demonstrating the practicality of the equipment design.

[0015] This modular dry powder fire extinguisher structure, through the inclusion of a connection seat, limiting back frame, spray lever, tank body, limiting ring seat, lifting handle, first and second sealing pads, movable groove, movable frame, limiting pull block, and pull handle, further enhances the overall usability of the equipment. During daily use, operators can simply slip the limiting ring seat over the tank body, with the first sealing pad on the inner wall of the limiting ring seat fitting snugly against the second sealing pad on the side of the tank body. The entire tank body can then be lifted by gripping the pull handle on the back of the limiting ring seat. Simultaneously, during routine use of the limiting back frame and spray lever, the limiting pull block can be slid along the movable frame within the movable groove on the side of the limiting back frame using the pull handle. This allows for adaptive limiting of the limiting back frame during use, ensuring the stability of the dry powder fire extinguisher when not in use, demonstrating the comprehensiveness of the equipment design.

The high-pressure valve 14 inside the screw-on base 12 can be sealed to the control nozzle 2 on the surface of the connecting base 1. Then, the safety bolt 3 on the surface of the control nozzle 2 can be pulled open, and the dry powder fire extinguisher can be controlled and activated directly at the spraying lever 5 of the limiting back frame 4.

[0024] The tank body 6 is located at the bottom of the connecting seat 1. A limiting ring seat 7 is fitted on the outer surface of the tank body 6. A lifting handle 8 is fixedly connected to the back of the limiting ring seat 7. A first sealing pad 9 is provided on the inner wall of the limiting ring seat 7. A second sealing pad 10 is provided on the side of the tank body 6. A support base 11 is fixedly connected to the bottom of the tank body 6. A screw-on seat 12 is fixedly connected to the top of the tank body 6. A sealing ring 13 is provided at the top of the screw-on seat 12. A high-pressure valve 14 is provided inside the screw-on seat 12. The limiting ring seat 7 is fitted onto the tank body 6 for replacement.
