The model utility content
The purpose of model utility: in order to provide a kind of easy to use, compress quick and time saving and energy saving high pressure two-stage inflater.
in order to reach as above purpose, the utility model is taked following technological scheme: comprise base and the part of calming the anger, the secondary inner tube is arranged on described base, secondary inner tube inside is connecting one-way valve, the outlet of described one-way valve is connecting tracheae, the second piston pipe that secondary inner tube nested inside second piston moving up and down and traction second piston are arranged, secondary inner tube overcoat first stage piston, the first stage piston outside can move up and down along with the one-level outer tube for one-level outer tube and first stage piston, described one-level outer tube and second piston Guan Jun are fixedly connected on handle, between described one-level outer tube and secondary inner tube, sealed cap is arranged, sealed cap is installed on secondary inner tube top, there is vent described secondary inner pipe wall top, also comprise the half-duplex channel of closing when open and up when the one-level outer tube is descending on described first stage piston.
Adopt as above the utility model of technological scheme, soluble at least problem is: a kind of understructure of inflating is provided; Second piston provides a kind of air-inflating device, because can be realized the function of inflating in the inside motion of second piston pipe; The device that provides a kind of multistage compression air efficiently to inflate.
The further technological scheme of the utility model is, the outlet of described one-way valve is also connecting bleed screw.
The further technological scheme of the utility model is, on described base, the outlet of one-way valve also is equipped with pressure gauge.
The further technological scheme of the utility model is, described first stage piston and base contacted position is equipped with the sound deadening shock absorption packing ring.
The further technological scheme of the utility model is, the first stage piston seal ring is housed on described first stage piston, and the second piston seal ring is housed on described second piston.
The further technological scheme of the utility model is, described one-level outer tube and second piston Guan Jun are connected on fixed block, and described fixed block is bolted handle.
The half-duplex channel of closing when open and up when the fooled one-level outer tube of described first stage piston is descending is Non-return air valve.
Adopt as above the utility model of technological scheme, have following beneficial effect: the compression efficiency to air is high, and is easy to use, safe and efficient, greatly saves manpower, also comprises in addition bleed screw, therefore can pressure release when air pressure is higher.
Description of drawings
Accompanying drawing is the model utility structural representation;
Wherein: 1 handle; 2 sealed caps; 3 bleed screws; 4 one-level outer tubes; 5 secondary inner tubes; 6 second piston pipes; 7 first stage pistons; 8 second pistons; 9 first stage piston seal rings; 10 pressure gauges; 11 second piston seal rings; 12 tracheaes.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described;
in order to reach as above purpose, the utility model is taked following technological scheme: comprise base and the part of calming the anger, secondary inner tube 5 is arranged on described base, secondary inner tube 5 inside are connecting one-way valve, the outlet of described one-way valve is connecting tracheae 2, the second piston pipe 6 that secondary inner tube 5 nested inside second pistons 8 moving up and down and traction second piston 8 are arranged, secondary inner tube 5 overcoats first stage piston 7, first stage piston 7 outsides can move up and down along with one-level outer tube 4 for one-level outer tube 4 and first stage piston 7, described one-level outer tube 4 and second piston pipe 6 all are fixedly connected on handle 1, between described one-level outer tube 4 and secondary inner tube 5, sealed cap is arranged, sealed cap is installed on secondary inner tube top, above described secondary inner tube 5 tube walls, vent is arranged, also comprise the half-duplex channel of closing when open and up when one-level outer tube 4 is descending on described first stage piston 7.
