Description

Technical Field

[0001] This utility model belongs to the field of reinforced fire extinguisher valves, and specifically relates to a reinforced fire extinguisher valve. Background Technology

[0002] The fire extinguisher valve is the core control component of a fire extinguisher, playing a crucial role in opening and closing the extinguishing agent release channel. Its structural stability and operational reliability directly affect the fire extinguishing efficiency. Existing fire extinguisher valves typically include basic components such as the valve body, pressure rod, and handle, achieving extinguishing agent release control through mechanical linkage. To adapt to different usage scenarios, the valve must possess sufficient structural strength to withstand external environmental impacts such as collisions and vibrations, while ensuring the stable connection of the operating components to guarantee normal operation in emergencies and meet basic fire safety requirements.

[0003] Existing technologies have specifically developed some reinforced fire extinguisher valves. For example, Chinese patent publication number "CN217119194U" discloses "A Reinforced Fire Extinguisher Valve". This reinforced fire extinguisher valve adopts the cooperation of multiple mechanisms, has strong functionality, and uses an interlocking magnetic attraction method to replace the pin for connection and fixation. By controlling the opening of the magnet, the connection is controlled to close. When the magnet is closed, it will automatically rebound under the operation of the spring rod, quickly opening the valve so that the fire extinguisher can be used quickly and ensuring the timeliness of fire fighting.

[0004] Although the connection is controlled by opening the magnet, and when the magnet is closed, the valve will automatically rebound under the action of the spring rod to quickly open the valve so that the fire extinguisher can be used quickly and ensure the timeliness of fire fighting, the above-mentioned reinforced fire extinguisher valve has a detachable structure where the handle and the fixed cylinder are connected to the valve body through the mounting hole. The lever is only connected to the valve body by the movable bolt, and neither of them uses a snap-fit ​​method. This makes it necessary to accurately align the parts during the later assembly, which takes a long time. When replacing parts, the lack of snap-fit ​​positioning makes the disassembly and installation process cumbersome and affects efficiency. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a reinforced fire extinguisher valve to solve the problems of reinforced fire extinguisher valves.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A reinforced fire extinguisher valve includes a fixing plate, on the upper end of which a valve body is fixedly mounted. The upper ends of the valve body have internal snap-fit ​​components on both sides. A pressure shell is snapped onto the outer ring of each snap-fit ​​component. A pressure rod is integrally formed on one side of the pressure shell. A metal block is fixedly connected to the bottom of the pressure rod.

[0009] As a preferred technical solution, a connecting rod is fixedly installed at one end of the pressure rod near the handle, and the end of the connecting rod away from the pressure rod is fixedly installed at the end of the metal block away from the controllable magnetic fixing component. The metal block is fixedly connected to the bottom of the pressure rod through the connecting rod.

[0010] As a preferred technical solution, the controllable magnetic attraction fixing assembly includes a fixing cylinder, a controllable magnet, a rotating wheel, and fixing holes. Two positioning holes are opened inside one side of the fixing cylinder, and a connecting groove is provided inside the fixing cylinder. The controllable magnet is fixedly installed inside the connecting groove, and a rotating wheel is rotatably installed on one side of the fixing cylinder.

[0011] As a preferred technical solution, a bearing seat is fixedly installed at one end of the fixed cylinder near the rotating wheel, the rotating wheel is rotatably installed on one side of the fixed cylinder through the bearing seat, and the metal block is slidably installed inside the fixed cylinder through the connecting groove.

[0012] As a preferred technical solution, the connecting seat has an insertion groove on the side away from the valve body, and a second slot is provided on both sides of the insertion groove. The insertion block is slidably installed inside the connecting seat through the insertion groove.

A second locking block is fixedly installed at the end of the second spring away from the second slot. The second locking block is engaged and installed inside the second slot.

[0014] In summary, the present invention has the following main advantages:

[0015] First, the snap-fit ​​assembly, through the engagement of the first snap-fit ​​block and the first snap-fit ​​groove, combined with the elastic force of the first spring, makes the pressure shell and the valve body tightly connected, significantly improving the vibration and impact resistance and avoiding the problem of easy loosening in traditional connection methods. The snap-fit ​​structure of the connecting seat and the plug-in block, with the cooperation of the second snap-fit ​​block and the second snap-fit ​​groove, ensures that the handle is firmly installed and can remain stable even under frequent operation or external force collision, reducing the risk of failure.

[0016] Secondly, the controllable magnetic fixing component and the metal block provide stable magnetic fixing when not in use, preventing accidental valve opening due to accidental contact of the pressure rod, and ensuring safety during storage and transportation. The rigid connection between the pressure rod, connecting rod and metal block enables precise transmission of operating force and rapid response when the pressure rod is pressed, ensuring timely release of extinguishing agent in emergency situations and buying valuable time for fire extinguishing.

[0017] Third, the snap-fit ​​structure design of each component eliminates the need for complex tools. The disassembly and installation of components such as the pressure shell and handle can be completed with a simple pressing action, which greatly simplifies the maintenance and replacement process, reduces labor costs, and the sliding fit between the plug block and the connecting seat, as well as the snap-fit ​​method between the pressure shell and the valve body, ensures precise component positioning. No repeated adjustments are required during assembly, which improves assembly efficiency and makes it suitable for large-scale production. Attached Figure Description

The sliding fit between the plug-in block 18 and the connecting seat 8, as well as the locking method between the pressure shell 2 and the valve body 9, ensures precise component positioning. Assembly does not require repeated adjustments, improving assembly efficiency and making it suitable for large-scale production.

[0032] Operating principle and advantages: The valve is based on the fixed plate 10, and the valve body 9 fixed at the upper end is the core load-bearing component. The snap-fit ​​components 22 on both sides of the upper end of the valve body 9 support the first snap-fit ​​block 14 through the first spring 24 in the first slot 23, which engages with the first snap-fit ​​groove 15 inside the pressure shell 2, so that the pressure shell 2 is stably fitted on the upper end of the valve body 9. The pressure rod 1 on one side of the pressure shell 2 is fixed to the metal block 16 through the connecting rod 17 to form a linkage structure. The connecting seat 8 at one end of the valve body 9 slides into the insertion block 18. The second spring 19 in the second slot 20 on both sides of the insertion block 18 pushes the second snap-fit ​​block 7 and snaps into the second snap-fit ​​groove 25 of the insertion slot 26 of the connecting seat 8, firmly fixing the handle 4. At this time, the metal block 16 just slides into the controllable magnetic attraction fixing component 5 at the upper end of the handle 4. The controllable magnet 12 generates magnetic force to attract the metal block 16, realizing The double fixation of the lever 1 and handle 4 ensures that the valve is tightly closed when not in use. In case of emergency, first release the magnetic fixing component 5 from the metal block 16, then press the lever 1. The lever 1 drives the pressure shell 2 to overcome the elastic force of the first spring 24 in the locking component 22, causing the first locking block 14 to retract from the first locking groove 15. The pressure shell 2 rotates relative to the valve body 9, opening the extinguishing agent release channel. After the fire is extinguished, release the lever 1. The first spring 24 resets and pushes the first locking block 14 back into the first locking groove 15. The pressure shell 2 returns to its position, and the metal block 16 is attracted by the controllable magnet 12 again, restoring the initial fixed state. If it is necessary to disassemble or replace parts, press the first locking block 14 to compress the first spring 24 to remove the pressure shell 2; press the second locking block 7 to compress the second spring 19 to pull out the plug block 18 and separate the handle 4. The operation is convenient and does not damage the components.
