Form on 72 and in the waistband support plate 74 the arcuation positioning end being adapted to the arc-shaped regulatory region 75.This technology side
Case specifically discloses a kind of mode of adjusting.By between support plate damping block 72 and waistband support plate 74 with cambered
Contact, can be realized the adjustment of 74 angle of waistband support plate, to more be bonded human body.
Preferably, 2 side of oxygen tank is connected with pressure reducing valve 17, and 17 side of pressure reducing valve is connected with aeration valve by tracheae
18, aeration valve 18 is arranged in the lower end of the air bag body 8 and is connected to the air bag body 8 upward.The technical program specifically discloses
A kind of layout designs of aeration valve 18.It is automatic air supply device that being connected to of pressure reducing valve 17 and aeration valve 18, which can constitute one,
Mainly the inside is provided with pressure auto-balancing device, so that interference of the automatic air supply device from air pressure change.
Embodiment two: the technical program and embodiment one are almost the same, the difference lies in that inlet suction port 51, gas stream
Road is different with the connection type of peace and quiet 4 three of tank.It is the downside that gas flow is placed on to peace and quiet tank 4 before, by peace and quiet tank 4
Lower end aperture and gas flow, which are realized, to be connected.And in the present embodiment, gas flow can be in the connection and sealing with peace and quiet tank 4
Mode can be connected by intermediate nut and be realized, i.e., there is thread segment in gas flow one end, and peace and quiet tank 4 also has thread segment, passes through spiral shell
Change in location of the mother between two thread segments realizes connection.Certainly the connection type between gas flow and peace and quiet tank 4 is realized
There are many, only specific two of them mode here.
Above-described embodiment is only presently preferred embodiments of the present invention, not limits the protection scope of the utility model according to this, therefore:
The equivalence changes that all structures under this invention, shape, principle are done, should all be covered by within protection scope of the present invention.
