The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail: a kind of air pressure chest expander, its structure mainly are made of inflator 8, vent plug 3, tension arm 13, direction adjusting apparatus, great efforts minor adjustment device etc.
See Fig. 1, Fig. 2, described inflator 8 both sides are respectively arranged with tension arm 13, the inboard of described inflator 8 is provided with vent plug 3, described vent plug 3 arranged outside have sealing device, as preferably, described sealing device is a sealing ring 5, and vent plug 3 is divided into left air cavity 100, right air cavity 200 with inflator 8, it is porose 6 that described vent plug 3 is provided with, and an end of described vent plug 3 is connected with tension arm 13.
One end of described inflator 8 is provided with great efforts minor adjustment device, described great efforts minor adjustment device, comprise adjusting knob 1, described adjusting knob 1 inboard is screwing adapter sleeve 2, and an end of adapter sleeve 2 heads on air pressure valve 4, is provided with first elastic parts 7 between the other end of air pressure valve 4 and the vent plug 3, and the cylinder 15 that air pressure valve 4 ends are provided with stretches in the hole 6, described cylinder 15 is tapered, and as preferably, described first elastic parts 7 is a stage clip.
The other end of described inflator 8 is provided with direction adjusting apparatus, described direction adjusting apparatus, comprise direction regulating wheel 11, described direction regulating wheel 11 is provided with bulla 12, pore 16, described bulla 12 is the soft rubber material, bulla 12 corresponding positions, inflator 8 arms are provided with aperture 14, and the middle part of described direction regulating wheel is provided with second elastic parts 9, as preferably, described second elastic parts 9 is a stage clip.
Power thrusts is regulated, and when the needs stretching, when need not the pressure exercise, sees Fig. 3, Fig. 4, Fig. 5, Figure 11:
Direction regulating wheel 11 is rotated to Fig. 3, Fig. 4, during the position of Fig. 5, bulla 12 is arranged on direction regulating wheel 11 outsides, also be that bulla 12 heads are towards pore 14, afterbody outwardly, behind stretching vent plug 3, external pressure is greater than the air pressure of left air cavity 100, bulla 12 tightly is attached to direction regulating wheel 11, and the pore 16 of stifled prescription on regulating wheel 11, at this moment, the gas of left air cavity 100 air cavity 200 apertures 6 of can only keeping right replenish, left side air cavity 100 volumes become big, when pressure reduced, external pressure needed to stretch more energetically during always greater than left air cavity 100, when back compressing, beginning is pushed vent plug 3 to left air cavity 100 because left air cavity 100 pressure are little, and compression is to need not effort, when left air cavity 100 pressure increase, and during greater than external pressure, at this moment, bulla 12 is blown to the shape as Figure 11, gas in the left side air cavity 100 flows out from bulla 12, thereby in the air cavity 100 of a balance left side, outer air pressure, compression also need not effort, can be with vent plug 3 toward back pressure.
When needs pressure is taken exercise, when need not stretching, see Fig. 6, Fig. 7, Fig. 8, Figure 12
Direction regulating wheel 11 is rotated to Fig. 6, Fig. 7, the position of Fig. 8, bulla 12 is arranged on direction regulating wheel 11 inboards, be that bulla 12 afterbodys are towards pore 14, head outwardly, when the compression vent plug 3 after, external pressure is greater than the air pressure of left air cavity 100, bulla 12 tightly is attached to direction regulating wheel 11, and the pore 16 of stifled prescription on regulating wheel 11, at this moment, the gas of left air cavity 100 air cavity 200 of can only keeping right sees through aperture 6 and replenishes, left side air cavity 100 volumes diminish, pressure increases, and left air cavity 100 pressure need big force compresses always greater than external pressure, when stretching outward, beginning is because left air cavity 100 pressure are big, and to the right outside the air cavity 2, stretching need not effort with vent plug 3, when left air cavity 100 pressure reduce, and during less than external pressure, at this moment, bulla 12 is blown to the shape as Figure 12, extraneous gas flows in the left air cavity 100 from bulla 12, thereby in the air cavity 100 of a balance left side, outer air pressure, stretching also need not effort, vent plug 3 can be pulled outward.
Another embodiment of bulla 12: see Figure 13, described bulla head projection and regulating wheel are provided with certain clearance, make its energy move left and right.
When direction regulating wheel 11 is rotated to the position of Fig. 9, at this moment, the still compression that no matter stretches, the gas of left air cavity 100 can both be rapidly and extraneous balance, can realize the action that stretches, compresses easily.
Size adjustment firmly, stretch or used pulling force or pressure during compression vent plug 3, under identical speed, change with the variation of the hole on the vent plug 36 with the gap of cylinder 15, the gap is big more, and left air cavity 100 air pressure just can replenish rapidly more, used pulling force or pressure are just more little, the gap is more little, and it is also slow more that left air cavity 100 air pressure replenish speed, and used pulling force or pressure are just big more.
During rotation dynamics adjusting knob 1, drive adapter sleeve 2 and rotate together, elastic parts 7 heads on air pressure valve 4 keeps in touch it all the time with adapter sleeve 2, during adapter sleeve 2 rotations, drives air pressure valve 4 move left and right.And air pressure valve 4 is tapers with 6 cooperation places, hole on the vent plug 3, like this during air pressure valve 4 move left and right, hole 6 on the vent plug 3 and the and then variation of the gap of cylinder 15, thus reach draw, used pulling force or the adjusting of pressure size during pressure plug 3.
