Problems solved by technology
The waist belt of the positive pressure respirator interferes with the position of the fire safety belt, and the waist force of the positive pressure respirator cannot be realized
[0004] Based on this, it is desired to obtain a positive pressure respirator fire safety belt with the function of a fire safety belt. Unplug the connection to effectively solve the problem of interference between the positive pressure respirator belt and the fire safety belt. The positive pressure respirator fire safety belt can also protect the personal safety of the user

Embodiment
[0036] see Figure 6 and Figure 7 , the switch plate has two positions. After the buckle of the belt buckle is inserted into the matching slot of the belt buckle through the opening, the switch plate is in the first position. The buckle is loose; when it is necessary to remove the connection between the backboard and the positive pressure respirator, move the switch plate to the right and rotate it to the second position, the movable shaft and the concealed buckle groove of the belt buckle will be loosened, and the switch plate will The pressing part presses the buckle downwards, and at this time, the buckle is moved to the left to exit the matching slot of the buckle of the belt clip, and the cooperation between the buckle of the belt and the waist clip is released.

The invention relates to the technical field of positive pressure respirators, and particularly discloses a fire service life safety belt of a positive pressure respirator and a using method of the fire service life safety belt. Waist clamp inserting buckles are correspondingly connected to the two sides of a waist cushion and used for being matched with waist clamps correspondingly so as to achieve detachable connecting, a hidden buckle groove is formed in the lower side of each inserting buckle, a back plate is used for mounting the positive pressure respirator, and the waist clamps are correspondingly connected to the two sides of the back plate; and an opening communicating with the waist clamp inserting buckles for being matched with a clamping groove is formed in the end, away from the back plate, of each waist clamp, sliding grooves are formed in the two sides, matched with the clamping grooves correspondingly, of the waist clamp inserting buckles, and a moving shaft is connected into each sliding groove in a matched mode and used for being matched with each hidden groove. Compared with the prior art, the problem that a positive pressure respirator belt cannot meet the requirements of a fire service life safety belt is solved, the fire service life safety belt can be connected with the positive pressure respirator waist clamps in a quick inserted and pulled mode, the positive pressure respirator equipment with the fire service life safety belt function is obtained accordingly, and the fire service life safety belt is simple in structure, safe, reliable, safer to use,fast and convenient to operate and high in applicability.
Description
technical field [0001] The invention relates to the technical field of positive pressure respirators, in particular to a fire safety belt for positive pressure respirators and a usage method thereof. Background technique [0002] Positive pressure air respirators, as respiratory protection equipment, are widely used in various fields such as fire rescue, metallurgy, chemical industry, shipbuilding, municipal and military. The air respirator is composed of a cylinder assembly, a decompression system assembly, a mask, an air supply valve and a back frame assembly. When in use, wear the whole set of positive pressure respirator on the back of the human body through the back frame assembly, fill the air cylinder assembly with 30Mpa compressed air, connect the air cylinder to the pressure reducing valve on the air respirator, and open the cylinder valve Finally, the compressed air in the gas cylinder enters the pressure reducing valve, passes through the medium pressure pipe aft...
