Fixing frame for firefighting air breather

Abstract

The invention relates to the technical field of air breather, in particular to a fixing frame for a firefighting air breather; the fixing frame for the firefighting air breather comprises a fixing frame main body, a base and a headrest; the headrest is rotationally connected with the upper part of the fixing frame main body through the headrest installation seat up and down; the fixing frame further comprises an upper cross bracing, an upper backrest, a lower cross bracing and a lower backrest for fixing and supporting a gas cylinder between the headrest and the base from top to bottom; the upper cross bracing is connected with the headrest installation seat and can move up and down and back and forth, the lower cross bracing is connected with the fixing frame main body and can move up anddown and back and forth, and the upper backrest can be expanded and unfolded; the fixing frame further comprises a safety belt fixing plate arranged on the fixing frame main body and a link mechanismpositioned at one side of the fixing frame main body for driving the headrest to rotate upward or downward. The fixing frame for the air breather provided by the invention is very convenient for installation and unloading operation of the air breather, and is safe and adjustable so as to adapt to the use of cylinders with different sizes.

Description

technical field [0001] The invention relates to the technical field of air breathing apparatus, in particular to a fire-fighting air breathing apparatus fixing frame. Background technique [0002] In the actual combat of fire rescue, time is life. Before arriving at the destination, firefighters often carry the air respirator (hereinafter referred to as the air respirator) so that they can directly enter the battle when they reach the destination, so it is particularly important to fix the air respirator. It is important not only to be safe and comfortable when the firefighter is sitting, but also to allow the firefighter to get up and take it out quickly. However, in actual combat at present, most of the air-breather fixing frames cannot meet the above requirements, and some need to wait for the car to stop before wearing the air-breathing device, and the structural design of the air-breathing device fixing frame is unreasonable, and there are the following problems: (1) T...

Problems solved by technology

However, in actual combat at present, most of the air-breather fixing frames cannot meet the above requirements, and some need to wait for the vehicle to stop before wearing the air-breathing device, and the structural design of the air-breathing device fixing frame is unreasonable, and there are the following problems: (1) The air breathing apparatus cannot be taken out quickly, thereby affecting the rescue response time; (2) Most of the existing air breathing apparatus fixing frames rely on the headrest to fix the gas cylinder, and the headrest mounting seat is often opened and closed, causing the headrest to be easily damaged. Damaged; (3) The existing air exhaler fixing frame is not adjustable and cannot be used for gas cylinders of different sizes, which is inconvenient to operate and use
