Abstract
The utility model relates to a high pressure inflator, comprising a cylinder sleeve, a piston and a base. An air outlet is arranged on the base. A check valve is arranged at the middle part of the piston. Sealing rings are arranged at the points where both ends of the piston are contacted by the cylinder sleeve. A restoring spring is installed between the piston and the top end of the cylinder sleeve. The utility model adopts the operational mode that the cylinder sleeve is matched with the piston. The piston is accompanied with the functions of the check valve and an air storage tank, so that high pressure can be produced when the piston is operated. Simultaneously, the weight and the volume of a product are reduced. The operation modes of foot pressing and hand pressing are adopted. The utility model has the advantage of convenient use.
Description
The utility model relates to a kind of device by the generation of the relative movement between piston and cylinder sleeve pressurized gas, particularly a kind of gas cylinder.
In daily life, run into to bicycle, motorcycle through regular meeting and to inflate, give the situation of ball inflation; adopt electronic pump simple, convenient when inflating, working efficiency is also high, but its cost height; moving inconvenience, is not that the repairing place of specialty generally can not adopted.The most frequently used is manual pump, and existing pump is played gas and required great effort very much, and the gas pressure of generation is limited, and working efficiency is not high.
The purpose of this utility model provide a kind of simple in structure, volume is little, it is laborsaving to inflate, the gas cylinder of high working efficiency.
The purpose of this utility model is achieved in that a kind of gas cylinder, comprise cylinder sleeve, piston and base, the steam outlet pipe of on base, establishing, the piston middle part is provided with check valve, there is seal ring piston two ends and cylinder sleeve contacting point, between piston and cylinder sleeve Xiang Duan Returnning spring are housed.Be provided with clamp matches with deck on the base in the cylinder sleeve bottom.
Gas cylinder provided by the utility model, owing to adopt cylinder sleeve to match with piston, piston has the effect of check valve and gas holder concurrently, makes it can produce high pressure when operation, has reduced the weight and volume of product simultaneously again; The utility model can adopt pin and two kinds of modes of operation of hand, and is very easy to use.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is this practical structural representation.
Structure of the present utility model is: a kind of gas cylinder, comprise cylinder sleeve 1, piston 2 and base 3, the steam outlet pipe of on base 3, establishing 4, piston 2 middle parts are provided with check valve 5, there is seal ring 6 piston 2 two ends and cylinder sleeve 1 contacting point, between piston 2 and 1 end of cylinder sleeve Returnning spring 7 are housed.Be provided with clamp 8 matches with deck 9 on the base 3 in cylinder sleeve 1 bottom.
When the utility model uses, press cylinder sleeve 1 and move down, the check valve 5 on the piston 2 is opened, and gas enters piston 2 from cylinder sleeve 1 by check valve 5, and the seal ring 6 at piston 2 two ends makes and keeps airtight between cylinder sleeve 1 and the piston 2.Press cylinder sleeve 1 repeatedly, the gas pressure in the piston 2 constantly increases, and the pressurized gas of generation are discharged from the steam outlet pipe 4 on the base 3.
After hours, can press down cylinder sleeve 1, clamp 8 on the cylinder sleeve 1 is stuck in the deck 9 on the base 3, cylinder sleeve is fixed, reduce the volume of pump.
Claims (2)
1, a kind of gas cylinder comprises cylinder sleeve, piston and base, and the steam outlet pipe of establishing on base is characterized in that: the piston middle part is provided with check valve, and there is seal ring piston two ends and cylinder sleeve contacting point, between piston and cylinder sleeve Xiang Duan Returnning spring are housed.
2, gas cylinder according to claim 1 is characterized in that: be provided with clamp in the cylinder sleeve bottom and match with deck on the base.
