Description

Technical Field

[0001] The utility model relates to the field of fire-fighting equipment, in particular to a pressure indicator connector for a fire extinguisher. Background Art

[0002] The pressure indicator installed on the valve of traditional portable fire extinguishers and cart-type fire extinguishers is directly connected to the internal pressure of the gas cylinder. When the pressure indicator needs to be removed, or the pressure indicator is damaged and needs to be replaced, or the pressure indicator needs to be removed for pressure calibration on dedicated testing equipment, the high-pressure driving gas in the gas cylinder must be released, resulting in waste and inconvenience in replacement. To this end, a new one-way valve described in the Chinese patent application document with application number 2024207177730 has been newly designed and installed on the fire extinguisher valve. When the pressure indicator is replaced or otherwise needs to be removed, the one-way valve will close after the pressure indicator is removed, preventing the high-pressure driving gas in the gas cylinder from leaking, thereby reducing waste and increasing the convenience of replacement.

[0003] Therefore, it is now necessary to design a pressure indicator connector for fire extinguisher that can be used in conjunction with this one-way valve. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a pressure indicator connector for a fire extinguisher. The technical problem to be solved is to provide a pressure indicator for a fire extinguisher. When the pressure indicator needs to be removed, the pressure indicator connector can be directly removed without releasing the high-pressure driving gas in the gas cylinder and refilling the gas after replacing the pressure indicator, thereby reducing gas waste and saving disassembly time, and having good economic benefits and social value.

[0005] To achieve the above-mentioned purpose, the utility model provides a pressure indicator connector for a fire extinguisher, comprising a base and a connector, wherein the connector is arranged at the bottom of the base; the base is connected to the pressure indicator, the connector is connected to the one-way valve, and the interior of the connector is provided with an internal thread matching the one-way valve.

[0006] Furthermore, a connecting block is fixed to one end of the connector, a connecting column is fixedly connected to the bottom of the base, and the connecting column passes through the connecting block and is fixedly connected to the connecting block.

[0007] Furthermore, the connecting column has a through hole inside.

[0008] Furthermore, the specification of the thread is 8V1.

[0009] The beneficial technical effects achieved by the utility model are:

[0010] Compared with the existing technology, the pressure indicator connector of the utility model is changed from an external thread to an internal thread, and is adapted to the one-way valve added to the fire extinguisher valve. When the pressure indicator needs to be removed, it can be directly removed without releasing the high-pressure driving gas in the gas cylinder and refilling the gas after replacing the pressure indicator, which reduces gas waste, saves disassembly time, and has good economic benefits and social value.
