Description

Portable tyre inflator pump

Technical Field

The utility model relates to an air compressor machine especially relates to a lightweight tire pump, belongs to pump technical field.

Background

The portable tire inflator pump is developed from a small-sized air compressor, is rapidly developed due to the advantages of small shape and wide application, and is widely used as an inflation tool for cars, minibuses, rubber boats, air cushion beds, various balls and the like.

At present, the main frame material of the core parts of the portable tire inflator pump which is popular in the market is generally zinc alloy or plastic. The zinc alloy body frame has the advantage of long service life, but the price of zinc alloy is rising all the time in recent years, the pump that adopts the zinc alloy body frame does not have the price advantage, hardly form the market, as shown in figure 1, the sealed traditional body frame 1 that leans on the riveting of zinc alloy body frame gas outlet, compress tightly zinc stopper 2, seal gasket 3 is sealed, if gas leakage in gas outlet, can not reprocess, simultaneously the weight ratio of zinc alloy is higher, also lead to the corresponding increase of pump weight, the trend of pump to little and light development has been violated, the plastic body frame has light in weight, the advantage of low price, but the plastic body frame melts easily in the high temperature, seriously influence the life-span, simple zinc alloy body frame or plastic body frame all have respective shortcoming, this kind of pump hardly adapts to present market demand.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: the problem of how to reduce cost when not influencing the pump life-span, and make the gas outlet can be reprocessed is solved.

In order to solve the technical problem, the technical scheme of the utility model provides a portable tire pump, including the pinion, on the rotation axis of motor was located to the pinion, pinion and gear wheel mesh mutually, the gear wheel is fixed on the host computer, the parcel has the cam in the gear wheel, the parcel has the bearing in the host computer, gear wheel and bearing coaxial coupling, be equipped with the cylinder body on the host computer, be equipped with piston ring and connecting rod in the cylinder body, the piston ring is connected with the connecting rod, the one end of connecting rod is passed through the steel column and is connected with the cam, a serial communication port, the host computer form by the body frame of plastic and the check valve plate of zinc alloy combine, check valve plate locates on the body frame, check valve plate's top is.

Preferably, the zinc check valve plate is connected with the main frame in a direct insertion manner.

Preferably, the main frame and the plastic plug are fixed through a direct-insert type buckle.

Preferably, the junction of check valve plate and body frame carry out sealing connection through first sealing washer, the junction of body frame and plastic stopper carries out sealing connection through the second sealing washer.

Preferably, check valve rubber and a check valve spring are arranged between the check valve plate and the plastic plug, the check valve rubber is arranged on the check valve plate, and the check valve spring is sleeved on the check valve rubber.

Preferably, the end of the motor is provided with a fan.

The utility model discloses an inflator pump host computer is split type, zinc alloy or plastic host computer simple not, its material is the combination of zinc alloy and plastic, reduce cost when not influencing the inflator pump life-span, the sealing device of gas outlet uses O type circle sealed, press the plastic stopper for the zinc check valve plate on the body frame, the equipment is convenient, light in weight and longe-lived, can reprocess, greatly reduced raw and other materials cost, the very big production that has made things convenient for, wide adaptability has, can adapt to the market demand, can be used in more extensive occasion. The problem of current lightweight tire pump weight heavy, the price is expensive, can not reprocess, the life-span is short is solved.
