Abstract
The utility model relates to a portable double-piston gas cartridge, which has a main structure that the utility model is provided with a gas cartridge body (5), a front end of which is provided with a cartridge cover (4). The front end of the cartridge cover (4) is provided with an interface (1). The interface (1) is interconnected with an inner cavity of the gas cartridge body (5) through a valve structure of a sealing ring (2) and a steel ball (3). The air cartridge body (5) is provided with a middle push bar (7), the front end of which is provided with a sand hole (14) and a sealing ring (6). An inner push bar (9) with a sealing ring (8) is arranged in the middle push bar (7). Inner sides of a rear end of the inner push bar (7) and the rear end of the gas cartridge body (5) are respectively provided with a guard ring (11) and a guard ring (10). A handlebar (12) is arranged on a rear end of the inner push bar (9). The utility model is characterized by portability, small volume, high pressure of loading gas, large aeration quantity, and strong practicability.
Description
The utility model relates to manual pump.
The pump stack shell of prior art is longer, and inconvenience is carried and collected.Though the small-sized pump volume of Chu Xianing is less in recent years, inflation pressure and capacity are also less, in use still feel more trouble.
The purpose of this utility model is, designs a kind of light double-piston inflator, has characteristics light, that volume is little and air pressure is high, aeration quantity is big.
The technical solution of the utility model is, described light double-piston inflator has front end that the air cylinder of tube cover has been installed, described tube cover front end is provided with the inflation interface, one-way valve structures and the air cylinder intracavity inter-connection of this inflation interface through forming by seal ring and steel ball, its structural feature is, be equipped with in the described air cylinder front end pore is arranged and be provided with the outside seal ring tubular in push rod, the air cylinder rear inside is equipped with guard ring, the tubular inner push-rod that front end is provided with the side sealing circle is contained in the described tubular in the push rod, should be provided with guard ring in middle putting back-end inboard, handle is equipped with in the rear end of described tubular inner push-rod.
Make below in conjunction with accompanying drawing and to further specify.
Description of drawings:; Fig. 1 is the integrally-built sectional view of reflection.In the drawings:
1-inflates interface, the 5-air cylinder,
The 2-seal ring, the 6-seal ring,
The 3-steel ball, push rod in the 7-tubular,
4-tube cover, the 8-seal ring,
9-tubular inner push-rod, the 12-handle,
The 10-guard ring, the 13-Aerating needle,
The 11-guard ring, the 14-pore.
As shown in Figure 1, structure of the present utility model is, it has front end that the air cylinder (5) of tube cover (4) has been installed, described tube cover (4) front end is provided with inflation interface (1), one-way valve structures and air cylinder (5) intracavity inter-connection of this inflation interface (1) through forming by seal ring (2) and steel ball (3), its technical characterstic is, be equipped with in the described air cylinder (5) front end pore (14) is arranged and be provided with the outside seal ring (6) tubular in push rod (7), air cylinder (5) rear inside is equipped with guard ring (10), the tubular inner push-rod (9) that front end is provided with side sealing circle (8) is contained in the push rod in the described tubular (7), should middle push rod (7) rear inside be provided with guard ring (11), handle (12) is equipped with in the rear end of described tubular inner push-rod (9).For ease of using, also can in handle (12), place the Aerating needle (13) of a prior art structure that can be connected with described inflation interface (1), be connected on interface (1) after taking out during use and locate, be used for to ball utensil inflation.
Design principle of the present utility model is (referring to Fig. 1), when extracting inner push-rod (9) out to middle push rod (7) rear end (right-hand member among Fig. 1), take middle push rod (7) out of, this moment, the inflator gas-storing capacity was the cavity volume sum that air cylinder (5) adds middle push rod (7), and gas storage space is maximum; In air cylinder (5), advance inner push-rod (9), the middle gas of push rod (7) is to air cylinder (5) in then compressing, when inner push-rod (9) front end (left end among Fig. 1) was pushed into middle push rod (7) front end, gas was discharged from interface (1) in push rod in the promotion (7) the pressurized gas cylindrical shell (5).The utility model is to improve to form on the inflator structure basis of prior art, middle push rod (7) and inner push-rod (9) are equivalent to the inflator piston (being double-piston) of two suits, the aeration quantity of a compressive charge inflator of its more onesize prior art increases by 2/3rds, and big 2.5 times than the pressurized gas pressure of the described inflator of prior art.
As known from the above, the utility model is a kind of light double-piston inflator, has the advantages that volume is little, inner gas pressure is high, aeration quantity is big, is the cutfit that is applicable to automobile, motorcycle, various ball aeratings, product is small and exquisite, light, be easy to carry, and is practical.
Embodiment: according to the utility model product of accompanying drawing and said structure, air cylinder (1) diameter and length are respectively 28 millimeters and 200 millimeters, all the other member relative set, other dependency structure adopts diagram prior art structure, and described air cylinder (5) and two push rods (7) (9) all form with the engineering plastics moulding.
Claims (2)
1, a kind of light double-piston inflator, there is front end that the air cylinder (5) of tube cover (4) has been installed, tube cover (4) front end is provided with inflation interface (1), one-way valve structures and air cylinder (5) intracavity inter-connection of this inflation interface (1) through forming by seal ring (2) and steel ball (3), it is characterized in that, be equipped with in the described air cylinder (5) front end pore (14) is arranged and be provided with the outside seal ring (6) tubular in push rod (7), air cylinder (5) rear inside is equipped with guard ring (10), the tubular inner push-rod (9) that front end is provided with side sealing circle (8) is contained in the push rod in the described tubular (7), should middle push rod (7) rear inside be provided with guard ring (11), handle (12) is equipped with in the rear end of described tubular inner push-rod (9).
