In order to solve the technical problem, the utility model discloses a technical scheme is:
the utility model provides a quick replenishing device of malleation oxygen respirator middling pressure oxygen, its includes external oxygen cylinder interface, pressure reducer, middling pressure pipe, oxygen manometer and reserve oxygen cylinder, wherein: the one end of external oxygen cylinder interface is connected with the gas outlet of reserve oxygen cylinder, and the other end of external oxygen cylinder interface is connected with the air inlet of pressure reducer, and the ration oxygen suppliment mouth of pressure reducer is connected with the one end of middling pressure pipe, and the other end of middling pressure pipe is used for being connected with trouble malleation oxygen respirator's manual supply mouth, and oxygen manometer is connected with the pressure reducer.
Optionally, the external oxygen cylinder interface, the pressure reducer, the medium-pressure conduit and the oxygen pressure gauge are integrally formed.
Optionally, the external oxygen cylinder connector and the pressure reducer are made of copper, and the medium-pressure conduit is made of plastic.
The utility model has the advantages that:
through setting up external oxygen cylinder interface, the pressure reducer, the middling pressure pipe, oxygen manometer and reserve oxygen cylinder, and the other end that sets up the middling pressure pipe is used for being connected with trouble malleation oxygen respirator's manual supply mouth, a device that can accomplish oxygen supply when malleation oxygen respirator high-pressure leakage appears fast is provided, the device can realize middling pressure oxygen supply fast, ensure can not cause the oxygen suppliment of the person of wearing to interrupt, also can avoid the face and the non-respiratory gaseous contact of the person of wearing, therefore can guarantee the life safety of the person of wearing to a very great extent. Therefore, compared with the prior art, the utility model has the advantages of small, light in weight, be convenient for rescue team to hand-carry, easy operation is convenient, can accomplish oxygen supply fast and ensure that the rescue personnel can withdraw safely when the disaster area operation.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, the device for rapidly supplying medium-pressure oxygen to a positive-pressure oxygen respirator in this embodiment includes an external oxygen cylinder interface 1, a pressure reducer 2, a medium-pressure conduit 3, an oxygen pressure gauge 4, and a standby oxygen cylinder 12, wherein one end of the external oxygen cylinder interface 1 is connected to an air outlet of the standby oxygen cylinder 12, the other end of the external oxygen cylinder interface 1 is connected to an air inlet of the pressure reducer 2, a quantitative oxygen supply port of the pressure reducer 2 is connected to one end of the medium-pressure conduit 3, the other end of the medium-pressure conduit 3 is used for being connected to a manual supply port 11 of a failed positive-pressure oxygen respirator 10, and the oxygen pressure gauge 4 is connected to the.
Optionally, external oxygen cylinder interface 1, pressure reducer 2, middling pressure pipe 3 and oxygen manometer 4 integrated into one piece for only need be connected reserve oxygen cylinder interface 1 with the gas outlet of reserve oxygen cylinder 12 earlier when the oxygen of middling pressure is supplied, be connected the other end of middling pressure pipe 3 with manual supply mouth 11 of trouble malleation oxygen respirator 10, ensure oxygen supply easy operation, thereby can accomplish the supply of oxygen fast.
Optionally, the external oxygen cylinder connector 1 and the pressure reducer 2 are made of copper, and the medium-pressure conduit 3 is made of plastic. The oxygen pressure gauge 4 is made of a combination of materials such as plastics and copper.
The utility model discloses in, behind the high-pressure oxygen in the reserve oxygen cylinder 12 decompression through pressure reducer 2, the manual supply mouth 11 through middling pressure pipe 3 and trouble malleation oxygen respirator links to each other to realize that middling pressure oxygen is incessant to be supplied with, the pressure condition of oxygen can be looked over at any time to oxygen manometer 4. Medium pressure oxygen refers to oxygen that is directly respirable to the wearer of a positive pressure oxygen respirator.
