Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

Referring to fig. 1, a modified air respirator interconnection device comprises a medium pressure hose 1, one end of the medium pressure hose 1 is connected with a quick connecting plug 2, one end of the medium pressure hose 1, which is far away from the quick connecting plug 2, is provided with a group of communication mechanisms, each communication mechanism comprises a three-way valve 3, the three-way valves 3 are respectively communicated with the medium pressure hose 1, a first quick plug 5 and a first quick socket 4, and the quick connecting plug 2, the first quick plug 5 and the first quick socket 4 are matched with the external oxygen supply tank valve body connector socket type. The first quick connector 5 is provided with a detachable sealing end cap, and the first quick connector 4 is also provided with a detachable sealing end cap.

Example two

Referring to fig. 2, the difference with the first embodiment is that the communication hose of the modified air respirator interconnection device adopts an edible spiral elastic hose 6, one end of the spiral elastic hose 6, which is far away from the quick connection plug 2, is provided with a multi-way valve 7, the multi-way valve 7 is connected with a plurality of three-way valves 3, the end of each three-way valve 3 is connected with a first quick plug 5 and a first quick socket 4 to form a multi-way, and the multi-way valve can be directly plugged with a plurality of connectors of an external oxygen supply tank valve body to share oxygen, and can also realize multi-way oxygen supply through the extending plugging of the modified air respirator interconnection device, and meanwhile, the multi-way valve has a plurality of expanded uses in space.

Example III

Common evacuation or emergency assistance

When fire fighters perform disaster relief, the first air breathing device used by the first member gives an indication of the second member to help co-evacuation or emergency relief when the pressure is insufficient. The team member 'B' immediately checks the pressure and the perfect condition of the air breathing apparatus used by the team member, the quick connecting plug 2 (male head) of the 'interconnection' device is connected with the quick socket (female head) of the other rescue device of the team member, then the first quick plug 5 (male head) of the 'interconnection' device is connected with the other rescue socket (female head) of the team member 'A' air breathing apparatus, and the first quick socket 4 is in a closed state, so that the air sharing of the team member 'A' and the team member 'B' is realized, and the common evacuation or emergency rescue is implemented.
