Abstract
The utility model relates to an air pump including: a handle is fixed on an external pipe body, and an internal pipe body which can move relative to the external pipe body is installed in the external pipe body. One end of the internal pipe body is connected with a piston, and a seal ring which matches the external pipe body is arranged on the piston. One end of a check valve is connected with the cavity of the external pipe body, and the other end communicates with the cavity of the internal pipe body. The air pump is provided with an inflation tube assembly and a base. The other end of the internal pipe body extends a connecting pipe integrated with the internal pipe body, and the connecting pipe is connected with the inflation tube. Because the connecting pipe is connected with the inflation tube, and the air pump is provided with only one joint, which can greatly reduce the possibility of leakage of the joint, and make the air passage of the air pump of the utility model be well sealed and reliably operate. Due to the base without the air passage, the air pump is simple in structure and low in production cost.

1, because the gas tube assembly is fixed on the air outlet of base, link to each other by the air flue in the base between interior tube body and gas tube, inflator is established two joints at least, and too much joint causes inflator to leak gas in gas replenishment process easily.
2, owing to be provided with air flue in the base, make the understructure complexity, make the cost height.
3, owing to be provided with seal washer between the surface of contact of the end face of interior tube body and piston, be provided with the seal ring with tight with piston on the interior tube body tube wall, during inflator work, interior tube body and piston are stressed bigger, the seal ring place is easy to gas leakage, makes that the functional reliability of above-mentioned inflator is undesirable.
Summary of the invention
The purpose of this utility model is: the inflator that a kind of simple in structure, reliable operation, gas circuit good airproof performance are provided.
The utility model is achieved through the following technical solutions:
A kind of inflator, comprise: handle is fixed on the outer tube body, be provided with the interior tube body that can move relative to outer tube body in the outer tube body, interior tube body one end is connected with piston, piston is provided with the seal ring with the outer tube body coupling, one end of one-way valve links to each other with the chamber of outer tube body, and the other end communicates with the chamber of interior tube body; Inflator is provided with gas tube assembly and base; It is characterized in that: the described interior tube body the other end extends the connecting tube with the interior tube body one, and this connecting tube links to each other with gas tube.
Advantage of the present utility model is: because the interior tube body the other end extends the connecting tube with the interior tube body one, this connecting tube links to each other with gas tube, inflator of the present utility model has only a joint, it can reduce the possibility of joint gas leakage greatly, make the gas circuit good airproof performance of the utility model inflator, reliable operation.Owing to need not to be provided with gas circuit in the base, make simple in structure, the low cost of manufacture of inflator.Use because interior tube body is made the air storage bag, make to the utlity model has high-pressure aerated function.
In the utility model, described connecting tube links to each other with connecting sleeve, and connecting sleeve links to each other with gas tube.Adopt connecting sleeve that connecting tube is linked to each other with gas tube, it is simple in structure, the gas circuit good airproof performance.
In the utility model, described connecting tube is bending-like.Connecting tube can adopt the connecting tube of U-shaped or L shaped bending-like, adopts the connecting tube of bending-like, connecting sleeve and base can be fixed, and when the pulling gas tube, guarantees to be connected reliably between gas tube and connecting tube.
In the utility model, described connecting tube is direct rod shape.It can realize goal of the invention of the present utility model equally.
In the utility model, the connection mouth of described connecting tube is the reducing shape.Be beneficial to gas tube and be connected.
In the utility model, described base is fixed on the connecting tube, and treadle is located on the base.
In the utility model, described one-way valve is installed in the interior tube body, and the valve seat of one-way valve is fixed in the interior tube body, and piston is installed on the outer wall of interior tube body, and the valve seat top of one-way valve is provided with Ka Tai, card platform fixed piston.One-way valve and piston adopt above-mentioned mounting structure, can make the good seal performance of one-way valve, and be simple in structure, easily manufactured; Make piston fixing more reliable simultaneously.
In the utility model, described interior tube body is installed one-way valve one end and is the reducing shape.It is beneficial to the installation one-way valve, and can improve the capacity of interior pipe.
