Abstract
The utility model relates to a double-pipe type high pressure air cylinder which comprises an inner air storing pipe and an outer air storing pipe which are sheathed together, a piston which is arranged on the upper port of the air storing pipe and provided with a one-way valve, and an air cylinder seat which is sheathed in the lower port of the inner air storing pipe in a stationary fit mode, wherein a ring groove is arranged on the combining surface of the air cylinder seat and the inner air storing pipe, and the inner surface of the inner air storing pipe is provided with an annular bulge at the position corresponding to the ring groove. Because the utility model adopts the structural characteristics, the air cylinder seat and the inner air storing pipe are firm combined together; because the setting of the annular bulge, the sealing effect of the combining surface of the air cylinder seat and the inner air storing pipe is also enhanced greatly.
Description
The utility model relates to a kind of double hose gas cylinder.
At present commercially available double hose gas cylinder with its working pressure height (can reach 12 barometric pressure), inflate light and do not have greasy dirt and be subjected to consumers in general's welcome deeply.But the double hose gas cylinder of this structure in use also has deficiency, promptly because the working pressure of interior gas storing pipe is big, make after date when using a section, sealability between interior gas storing pipe and the inflator seat reduces, loosening gas leakage even disengaging occur, shortened the working life of double hose gas cylinder.
The purpose of this utility model is not enough and a kind of durable in use and double hose gas cylinder that sealability is effective is provided with regard to being to overcome above-mentioned existing in prior technology.
The purpose of this utility model can realize by following technical measures:
The utility model comprises the inside and outside gas storing pipe that is sleeved on together, with the piston that has one-way valve that is arranged on described interior gas storing pipe upper end-hole, and the inflator seat in the gas storing pipe lower end mouth in being sleeved in the mode of stationary fit, the junction plane of described inflator seat and interior gas storing pipe is provided with a lockable mechanism.
Described lockable mechanism is to be opened in the annular groove on inflator seat and the interior gas storing pipe junction plane and to be arranged on the annular protrusion of interior gas storing pipe internal surface corresponding to described annular groove position.
Advantage of the present utility model just is to offer an annular groove on the junction plane of described inflator seat and interior gas storing pipe, and corresponding to described annular groove position one annular protrusion is set at interior gas storing pipe internal surface, thereby inflator seat and interior gas storing pipe are combined firmly, and, because the setting of described annular protrusion has also improved the sealing effect between inflator seat and the interior gas storing pipe junction plane widely.
The drawing of accompanying drawing is described as follows:
Fig. 1 cuts open schematic representation for master of the present utility model.
The utility model describes in further detail below in conjunction with specific embodiment (accompanying drawing):
As shown in the figure, the utility model comprises the inside and outside gas storing pipe 1,2 that is sleeved on together, with the piston that has one-way valve 34 that is arranged on described interior gas storing pipe 1 upper end-hole, and the inflator seat 5 in gas storing pipe 1 lower end mouth in being sleeved in the mode of stationary fit, described inflator seat 5 is provided with a lockable mechanism with the junction plane of interior gas storing pipe 1, described lockable mechanism is to be opened in the annular groove 6 on inflator seat 5 and interior gas storing pipe 1 junction plane and to be arranged on the annular protrusion 7 of interior gas storing pipe 1 internal surface corresponding to described annular groove 6 positions.
