Abstract
The utility model relates to a piston of an inflator, which replaces a traditional leather cup device. The piston of an inflator is composed of a piston body and an O-shaped sealing ring. The upper part of the piston body is provided with threads, and the lower part is provided with a trapezoidal sealing ring groove. The lower part of the ring groove is provided with an air vent. The utility model has the advantages of simple structure, easy fabrication and manufacture, convenient installation and operation, labor saving, low cost, and long service life.
Description
The utility model relates to a kind of piston of inflator pump.
At present, the leather cup device of inflator pump, working life is short, uses at most 1 year, and some months promptly is damaged at least, and dismounting is very inconvenient again, brings many troubles to the user.
The purpose of this utility model provides a kind of simple in structure, long service life, and easy disassembly is the piston of labour-saving inflator pump again.
For solving above-mentioned task, the solution that the utility model adopts is: the piston of inflator pump has replaced traditional leather cup, its piston includes piston body, O-ring seals, the top of piston body is provided with screw thread, be interlockingly connected with the nut of the inflator pump of need repackings, the piston body bottom is provided with trapezoidal closure gasket groove, is provided with vent in the annular groove bottom, and annular groove is provided with O-ring seals.
The solution that the utility model also adopts is: vent is two; Piston body is made of plastic.
The utility model has following advantage compared to existing technology:
1, simple in structure, processing and fabricating is easy, and cost is lower, compares with traditional leather cup device, and cost can reduce more than one times.
2, easy to install laborsaving, only need the inflator pump leather cup of need repacking is unloaded, remove pad, nut and this device screw thread is interlocked get final product, laborsaving especially during use.
3, long service life, a general piston can use more than 5 years.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Accompanying drawing is the piston three-dimensional structure diagram of inflator pump.
As shown in drawings, it includes piston body, O-ring seals, piston body 1 is made of plastic, its top is provided with screw thread 3, screw thread 3 setting that should be complementary with the nut of the inflator pump of need repackings, the piston body bottom is provided with trapezoidal closure gasket groove 4, and annular groove 4 bottoms are provided with two vents 5, and annular groove 4 is provided with O shape sealing rubber ring 2.
In use, only need the inflator pump leather cup of need repacking is unloaded, remove pad, nut and this device screw thread 3 is interlocked get final product.
