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. Because it cannot be moved, it is especially not suitable for use by 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.

Embodiment 1

[0027] Such as figure 1 and figure 2Among them, an inflation device for a portable fire extinguisher includes an inflation head 4, a bottom plate 14 and an inflation platform 13, and the inflation head 4 is provided with a pressure gauge 41. The inflatable head 4 is connected with a gas pipe 11, and the gas pipe 11 is connected with a foot valve switch 12, and then connected with gas sources such as gas cylinders. 1 is provided with a safety door 3, the safety door 3 is provided with a latch 31, and the door edge of the corresponding safety box 1 is provided with a socket 32. The top of the safety box 1 is an inflatable platform 13, such as image 3 and Figure 4 An inflation gap 15 is provided, the inflation head 4 is arranged on one side of the inflation gap 15, and the other side of the inflation gap 15 is welded with a bayonet socket 5. The other end of the inflatable head 4 is provided with a propulsion device, the propulsion device includes an eccentric wheel 6 and ...

Embodiment 2

[0032] Compared with the first embodiment, the embodiment of the present invention mainly exists that the inflatable head adopts the inflatable head with a valve, which can automatically open and close the inflatable valve, and figure 1 and figure 2 Compared, the pedal valve switch 12 has been omitted, and other structures are identical. The use of an inflatable head with a valve changes the prior art of using a pedal valve to control the opening and closing of an air source, and the gas between the foot valve and the inflatable head will be wasted during operation. Therefore, the use of an inflatable head with a valve has the benefit of saving gas.

[0033] Such as Figure 5 and Figure 6 , combined with Figure 1 to Figure 4 The inflatable head 4 with valve comprises valve body 45 and the valve core 44 that is sleeved in valve body 45, and valve core 44 is provided with hollow air guide hole 52, and valve core 44 head is provided with inflatable sealing ring 53, and sea...

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, and the push device and the air charging platform are form a safety box body, the air charging plat form is arranged on the upper part of the safety box body; 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

technical field [0001] The invention relates to the technical field of fire fighting, in particular to an inflation device for a fire extinguisher. Background technique [0002] 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 range of the fire extinguisher, and the inf...
