Description
Technical field
The utility model relates to a kind of manual inflator, further is meant the handy type inflator.
Background technique
Though the light double-piston pump of prior art can bring convenience to the user, its inflation pressure is limited, and is harder during use, and the inflation effect is undesirable, also has the single defective of inflatable object simultaneously.
Technology contents
The purpose of this utility model is, designs a kind of light double-piston gas cylinder, the characteristics that have the inflation pressure height, aeration quantity is big and it is light to use, are easy to carry and can inflate multiple inflation object.
The technical solution of the utility model is, described light double-piston gas cylinder has the main cylinder of band main piston rod, the inferior piston rod of band handle is housed in the leachy described tubular main piston rod of front end, its structural feature is, the front end of main cylinder is connected to the working head of calming the anger in a band gas storehouse, this working head of calming the anger has front end that the calming the anger of end cap of band pore has been installed, described rear end of calming the anger is to be communicated with described gas storehouse and relative gas storehouse cavity is more small-bore connecting port, in described the calming the anger vent plug is housed, this vent plug is made of the major part of band air cavity and microcephaly that front end surface has air drain and the middle cylinder between described major part and microcephaly, major part have air drain make its air cavity with the intermediolateral column external surface with calm the anger between the cavity that forms be connected, described vent plug microcephaly one end be equipped with a middle part have respectively connection than macropore with than the padding of aperture, during this padding drive fit is installed in and calms the anger.
Below make and further specifying.
As shown in Figure 1, the utility model has the main cylinder 9 of band main piston rod 7, front end has the inferior piston rod 4 that band handle 2 is housed in the tubular main piston rod 7 of pore 29, its structural feature is, the front end of main cylinder 9 is connected to the working head 12 of calming the anger in a band gas storehouse 11, this working head 12 of calming the anger have front end 14 installed band pore 23 end cap 22 calm the anger 13, described 13 the rear end of calming the anger is to connect with described gas storehouse 11 and relative gas storehouse 11 cavitys are more small-bore connecting port, described calming the anger is equipped with vent plug 25 in 13, this vent plug 25 is made of the major part 28 of band air cavity 15 and microcephaly 18 and the middle cylinder 17 between described major part 28 and microcephaly 18 that front end surface has air drain 19, major part 28 has air drain 16 that its air cavity 15 is connected with the cavity that forms between 13 of calming the anger with middle cylinder 17 outer surfaces, microcephaly's 18 1 ends of described vent plug 25 be equipped with a middle part have respectively be connected than macropore 20 with than the padding 24 of aperture 21, these padding 24 drive fits are installed in calms the anger in 13.Described vent plug 25 press the listed order of Fig. 1 with padding 24 and is installed, but also can as required vent plug 25 shown in Figure 1 and padding 24 reverse end for end installation (be one of them tune or the two all reverse end for end installation) in actual use respectively.Though padding 24 is installed for drive fit, it is dismountable, and available hand is installed its tune.
The utility model also disposes an air tube 27, and it can open the tegillum 1 of handle 2 rear ends and in the inner chamber 3 of time piston rod 4 that it is packed in time spent not; During use, padding 24 by position shown in Figure 1 tune install then tailstock 26 with air tube 27 place padding 24 than macropore 20, cover end cap 22 back air tubes and then stretch out by its pore 23, supply with various ball sporting appliances inflations and use.Take off air tube 27, then can be used for, various inflation apparatus inflations such as mountain bike, racing car, motorcycle and air bed, air dome, the ship of charging, air jacket bicycle.
Design of the present utility model and working principle are, draw-out handle 2, air by in each piston rod gap suction inflator, is inflated thing this moment and withstands padding 24 and make this padding 24 encase air drain 19 on the microcephaly 18 of vent plug 25, and the gas that is inflated the thing inner chamber can not enter in the inflator; Advance handle 2 to make the interior air of inflator be pressed into gas storehouse 11 earlier, 13 bores are smaller than gas storehouse 11 cavitys owing to calm the anger, air is in the process of further being compressed, then because the sudden change of gas chamber volume and produce highpressure in 13 calming the anger, this highpressure is in air drain 16 enters by the middle cylinder 17 and the cavity that forms between 13 of calming the anger, force padding 24 and vent plug 25 to be separated, then pressurized gas are inflated in the thing through charging into than macropore 20 (or than aperture 21) and than aperture 21 (or than macropore 20) by air drain 19.
As known from the above, the utility model is a kind of light double-piston gas cylinder, has the advantages that inflation pressure height, aeration quantity are big and use light (not hard), be easy to carry and can inflate multiple inflation object.
