The shortcoming of traditional inflator structure is：To ensure product overall structure firmly, satisfaction is normally used, and product is used The part for arriving is more, and assembling is complex, causes whole product cost higher.

The content of the invention

The technical problems to be solved in the utility model is：There is provided a kind of part it is few, assembly and disassembly are simple, performance good Inflator, solves the problems, such as that traditional inflator price and performance cannot be taken into account.

In order to solve the above-mentioned technical problem, the technical solution of the utility model there is provided a kind of inflator, including inner tube Component, one end of interior tube assembly is covered in outer tube through outer tube, and outer lid is fixed on the top of outer tube, and the bottom of outer tube is fixed In on base, it is characterised in that described base is by the 5th rubber ring and one end clamping of outlet piston and connects, outlet piston The other end is connected by ball with outlet tube assembly.

Preferably, described interior tube assembly includes inner tube, and with hand being connected, the lower end of inner tube passes through outer tube for the upper end of inner tube It is covered in outer tube, interior bottom of the tube is provided with groove and muscle position, and the second rubber ring is provided with groove.

Preferably, the two ends of described hand handle are plugged with hand stopper.

Preferably, the small tubes for increasing inner tube intensity are provided with the middle of described inner tube.

Preferably, the first rubber ring for playing cushioning effect is provided between described outer lid and inner tube.

Preferably, described base is provided with an aperture, and one end of outlet piston is in aperture.

Preferably, the bottom of described outlet piston is provided with the resilient muscle position of tool, and base is provided with what is matched with muscle position Groove, outlet piston is connected on base side wall by muscle position.

Outlet plunger designs of the present utility model because directly snapping in base, eliminate outlet lid and two rubber rings into This, and glue use, while the design of outlet piston portion is simple, Stability Analysis of Structures.Under conditions of properties of product are ensured, letter Change the packaging technology that structure reduces product, on the premise of properties of product are ensured, in terms of cost of parts and human cost two Reduction expense, realizes lifting of both product cost and performance.

Specific embodiment

To become apparent the utility model, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.

The utility model is a kind of inflator, and as shown in Figures 2 and 3, it includes hand 2, and 2 two ends are plugged with hand handle by hand Stopper 1, the upper end of inner tube 6 is connected with hand 2, and the lower end of inner tube 6 in outer tube 8, increases through outer lid 3 in the middle of inner tube 6 Small tubes 5 are used for increasing the intensity of inner tube 6, and hand is using being threadedly coupled, outer lid 3 is from the tooth line one end of inner tube 6 in the middle of 2 and inner tube 6 Penetrate, the first rubber ring 4 is provided between outer lid 3 and inner tube 6, play cushioning effect.Inner tube 6 is located in outer tube 8, by outer lid 3 cover fixed at the top of outer tube 8, and the bottom of inner tube 6 is provided with groove and muscle position, for placing the second rubber ring 7 and withstanding outer lid 3, Prevent inner tube 6 from extracting outer lid 3 out, the bottom of outer tube 8 is fixed on base 9, and base 9 is provided with an aperture, outlet piston 14 Bottom be provided with tool resilient muscle position, base 9 is provided with the groove matched with muscle position.One end of outlet piston 14 is located at aperture Interior, the 5th rubber ring 16 is inserted in one end of outlet piston 14, plays sealing function, further along in the groove push-in base 9 of base 9 Portion is connected, and bottom is smoothly shifted onto using the muscle position deformation of the bottom of outlet piston 14, and muscle position recoverable force withstands the side wall of base 9 so that Outlet piston 14 is fixed, and the other end of outlet piston 14 is connected by ball 13 with outlet tube assembly 15.

Wherein, outlet tube assembly 15 be used for inflator outlet, it include anti feedback plug, two the 4th of anti feedback plug both sides Rubber ring, escaping pipe and the mouth of pipe and the fixture for pressing from both sides valve inside.Outlet piston 14 is directly by the bottom of outlet piston 14 Muscle position is connected on the side wall of base 9, and whole Element Design is simple, Stability Analysis of Structures.

Outlet piston base design flexibility muscle position of the present utility model, loads base, and withstand bottom by the deformation of muscle position Seat side wall, is connected on base side wall, and outlet piston is inserted but do not pass base side wall, then is lived in outlet with a rubber ring sleeve Plug inner sealing.By the way of elastic screens, it is to avoid increase piston cap adds the 4th rubber ring to carry out sealing piston, reduces product The part consumption of product, is effectively simplified the component part and assembling process of product, and life is reduced under conditions of performance is ensured Produce cost.Reduce production cost.
