Box protection type fire extinguisher air charging device

Abstract

The invention discloses a box protection type fire extinguisher air charging device and relates to the technical field of fire fighting. The device comprises an air charging head with an air inlet and an air charging platform, wherein a push device is arranged on the air charging head. The device is characterized by also comprising a safety box body, wherein a panel on the upper part of the safety box body is the air charging platform; an air feed frame is arranged on the side face of the safety box body; an air charging gap is formed on the air charging platform on the upper part of the safety box body; the air charging head is arranged on one side of the air charging gap; a safety door is arranged on the air feed frame; a bottom plate is arranged inside the safety box body; the air charging head is provided with a valve; and a fire extinguisher detaching device is arranged on one side of the safety box body. The box protection type fire extinguisher air charging device can realize safe air charging of the fire extinguisher, and has the advantages of simple structure, small volume, low cost, increase of the fire extinguisher detaching device, and contribution to the use of fire extinguisher manufacturers and maintenance personnel.

Description

A box-type protective fire extinguisher inflation device technical field The invention relates to the technical field of fire fighting, in particular to an inflation device for a fire extinguisher. Background technique When producing and maintaining portable fire extinguishers, such as dry powder fire extinguishers, most of the inflation is manual. The person installs the gas nozzle on the gas head and starts to inflate the tank. After the pressure reaches a predetermined value, the gas nozzle is removed. Since there is no protective measure for the inflation device of the portable fire extinguisher when it is inflated, among the fire extinguisher practitioners who fill the fire extinguisher every year, most of the incidents of fire extinguisher explosion, death or injury are due to the explosive rupture of the fire extinguisher cylinder and the human body being ruptured by the explosion. During the entire inflation process, any part of the body is exposed to the blasting ...

AI Technical Summary

Problems solved by technology

The utility model uses the clamp inflation joint to directly inflate the fire extinguisher so that the personnel do not directly touch the fire extinguisher during the inflation process of the fire extinguisher, and the middle is separated by a steel plate. This structure protects the personal safety of the operator to a certain extent, but only the steel plate is used in the middle Separated, most of the space is exposed to the outside, and it will also cause damage to the personnel in the workplace in other exposed areas, posing safety hazards, and the structure also has a single function

The electric inflatable device adopts a large-scale production line, takes up a lot of space, has a complex structure, high cost, and is expensive. Since it cannot be moved, it is especially not suitable for fire extinguisher maintenance personnel.

In addition, the existing technology uses a pedal valve to control the opening and closing of the gas source, and the gas between the pedal valve and the inflatable head will be wasted during operation.
