Description
Technical field
This utility model relates to a kind of back board module, relates in particular to a kind of positive-pressure type air respiratorresuscitator back board module.
Background technology
The respiratory protection harness is to be used for defending anaerobic environment or effective utensil poisonous, that harmful gas is invaded the human respiratory tract.Air respiratorresuscitator the earliest is the negative-pressure type air respiratorresuscitator.1988, develop China's first generation positive-pressure type air respiratorresuscitator.Be mainly the positive-pressure type air respiratorresuscitator on the market now.The operation principle of positive-pressure type air respiratorresuscitator is: the compression cleaned air of storing in the gas cylinder enters full facepiece mask through the steam supply valve second depressurized again through the decompression of decompressor one-level, breathes use for the wearer.
The air relief valve fixed structure of general positive-pressure type air respiratorresuscitator is shown in accompanying drawing 1-3 on the market, air relief valve 3 ' top be provided with a handwheel 5 ', gas cylinder 6 ' be connected air relief valve 3 ' handwheel 5 ' on; High-voltage tube connect air relief valve 3 ' the high pressure mouth of pipe 10 ', air relief valve 3 ' bottom be provided with holder 8 ', holder 8 ' by bolt connect backboard 9 ' on fixed support 4 '.
The shortcoming of its existence is:
1. the trend of trachea deviates from outside the backboard, is hurt easily in use, leaks gas.
Holder on the air relief valve bottom position that is arranged on air relief valve cause between gas cylinder and the backboard apart from broad, the center of gravity of gas cylinder is away from backboard.
3. the fixed support stress surface that connects air relief valve and backboard is less, the weight of gas cylinder reasonably can not be distributed on the backboard.
4. owing to after air relief valve holder and air relief valve be fastenedly connected, can not suitably regulate, the connection angle of handwheel and gas cylinder can not suitably change, and causes the difficulty that is connected of gas cylinder and air relief valve.
The utility model content
The trend of trachea deviates from outside the backboard this utility model in the prior art in order to solve, easily accidental cuts; Between gas cylinder and the backboard apart from broad; The fixed support stress surface is less; Smoothly shortcoming not when handwheel uses, and designed a kind of positive-pressure type air respiratorresuscitator back board module, by locating slot is set on backboard, adjust the position of the holder of air relief valve, adopt the butterfly fixed support, suitably relax being connected between air relief valve holder and the air relief valve, obtain a kind of follow-on positive-pressure type air respiratorresuscitator back board module, it is simple in structure, and is stressed more reasonable, uses safer.
The purpose of this utility model is achieved in that and comprises backboard, vertically has the twice locating slot on the backboard.
Preferably, also comprise an air relief valve, it is fixed in the middle of the backboard bottom by a fixed support.
Preferably, also comprise a gas cylinder, be fixed on the air relief valve of backboard bottom that high, middle pressure pipe is connected with the high pressure mouth of pipe on the air relief valve, and embed the twice locating slot on the backboard respectively.
Preferably, a side relative with the high pressure mouth of pipe is provided with holder on the described air relief valve.
Preferably, described fixed support shape is butterfly, fixedlys connected with backboard, and the middle part of butterfly is provided with the U-shaped projection of a lateral openings, and described holder places the opening of this U-shaped projection, by bolt holder is fixedlyed connected with the U-shaped projection.
This utility model makes it compared with prior art owing to adopted above technical scheme, has the following advantages and good effect:
1. the trend of flexible pipe is improved to outside the backboard through between gas cylinder and the backboard by original deviating from, and is embedded in the locating slot, uses saferly, is not easy to be hurt.
2. holder is improved to the downside of air relief valve by original air relief valve bottom position, has shortened the distance of gas cylinder and backboard, makes the center of gravity of gas cylinder more press close to backboard.
3. this utility model air relief valve and backboard connected mode adopt the design of butterfly fixed support, effectively disperse the gravity of air relief valve and gas cylinder, and adopt interior outer plate, bolt fixed mode between butterfly fixed support and the backboard, are connected firmly.
4. because air relief valve and fixed support can also have the rotation of certain angle after being connected and fixed, so the connection angle of handwheel and gas cylinder also can suitably change, the connection between gas cylinder and the air relief valve is more convenient.
