Technical field of two-way inflator:

The utility model belongs to an air pump, in particular to a two-way inflator, which is suitable for the situations where the two-way inflator can be used for rickshaws, bicycle tyres and ball games. Before the production of the utility model, the air pump in the prior art is generally composed of a cylinder, a lever and a sealing sleeve. The top of the cylinder is provided with an air inlet, and the bottom of the cylinder is provided with an air hole. The task of the utility model is to overcome the shortcomings of the prior art and provide a bidirectional inflation pump with reasonable structure, bidirectional inflation, high use efficiency and convenient operation.

It is a two-way inflator mainly composed of rubber plate, fixing clip, O-ring, air inlet pipe, lever, pipe cover, thin bracket, connector, one-way discharge valve, seal, air pump pin and connecting head cover. The bottom and top of the pipe are respectively provided with an air inlet and an air inlet. The bottom of the lever is provided with an O-ring and a framework, an O-ring outer ring and a cylinder wall contact seal. There is a gap between the inner circle of the o-ring and the skeleton. The exhaust port at the top of the lever is provided with a one-way exhaust valve. The lever, one-way discharge valve, sealing block and air pump are integrally connected through a connector, the connecting head cover is arranged on the sealing block, and the fixing clip is arranged at the bottom of the pipe body. The rubber sheet is an oil resistant rubber product with a thickness of 0.2-0.8mm. The rubber sheet is an oil resistant rubber product with a thickness of 0.2-0.8mm.

Compared with the prior art, the utility model has a simple and reasonable structure, injects two-way air through the reciprocating motion of the lever, has the effect of pressurization, high use efficiency, convenient operation, safety and reliability, and has greater social and economic benefits and implementation value.

The working principle and implementation scheme of the utility model mainly include a rubber plate, a fixing clip, an O-ring, an air inlet, a pipe, a lever, a pipe cover, a slice, a connector, a one-way discharge valve, a sealing block, an air pump pin, and a connecting head cover. The bottom and top of the pipe are respectively an air inlet and an rubber plate. The bottom of the slice lever is provided with an O-ring and a skeleton, and the outer circle of the O-ring and the cylinder wall are contacted and sealed. There is a gap between the inner circle of the O-ring and the skeleton. The exhaust port at the top of the lever is provided with a one-way exhaust valve. The lever, one-way drain valve, sealing block and air pump are connected together through a connector.

Requirements for two-way inflator

1. A two-way inflator, mainly composed of rubber plate, fixing clip, O-ring, air inlet, pipe, lever, pipe cover, sheet, connector, one-way discharge valve, seal, air pump pin and connecting head cover, is characterized by that there is an O-ring and framework at the bottom and top of the pipe, and there is a gap between the inner circle of an O-ring and the framework. The exhaust port at the top of the lever is provided with a one-way exhaust valve. The lever, one-way drain valve, sealing block and air pump are integrally connected through a connector.

2. As claimed in claim 1, it is characterized by an oil resistant rubber product with a rubber sheet (1) thickness of 0.2-0.8mm.

3. As claimed in claim 1, it is characterized by an oil resistant rubber product with a rubber sheet (10) thickness of 0.2-0.8mm.

The utility model relates to a bidirectional inflator, which is mainly composed of a rubber plate, a fixing clip, an O-ring, an air inlet, a pipe, a lever, a pipe cover, a thin bracket, a connector, a one-way discharge valve, a seal, an air pump pin, and a connecting head cover. When the lever moves back and forth in the pipe, it exerts pressure.
