A one-way valve is provided at the opening of the barrel. Since the present invention adopts the above technical scheme, it has the following advantages: when the handle is lifted and pressed, the piston is driven to work by the pull rod, and the pump can be pumped when both are lifted and pressed, which makes pumping easier and doubles the efficiency. However, the structure of the above-mentioned patents is complex, resulting in high production costs, unsmooth air in and out, and unsuitable for application and promotion. To sum up, so I designed a pump for vehicle backup.

Utility model content

The technical problem to be solved by the utility model overcomes the existing defects, and provides an air pump for vehicle backup, which not only has a reasonable design, but also has low production cost. The pressure device can save more effort.

In order to solve the above technical problems, the utility model provides the following technical solutions:

The utility model provides an air pump used for vehicle backup, which comprises a stretch rod, a one-way valve, and a sealed piston. The one-way valve is installed below the stretch rod; the top of the stretch rod is installed There is the sealed piston; a supporting device is arranged on the periphery of the stretch rod; an anti-slip handle of the pump is installed in the center of the stretch rod; a connecting pipe is arranged under the anti-slip handle of the pump.

As a further optimization solution of the utility model, the lower end of the connecting pipe is connected with an inflatable head; both ends of the inflatable head are connected with air transmission pipes; the sealed piston is closely connected with the anti-skid handle of the pump.

As a further optimization scheme of the present invention, the upper end of the one-way valve is provided with inflating cylinders distributed at both ends of the connecting pipe; the lower part of the sealed piston is provided with a pressure changing device.

As a further optimization solution of the utility model, a pressure changing device is arranged behind the pumping cylinder; a stretching rod is arranged at the front of the pumping cylinder.

The beneficial effects achieved by the utility model are: an inflator used for vehicle backup, which has reasonable design and low production cost. The one-way valve is provided to save labor when inflating, smooth in and out of gas, and the pressure changing device can save labor.

detailed description

The preferred embodiments of the present utility model are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present utility model, and are not intended to limit the present utility model.

Embodiment: Please refer to Fig. 1, a kind of pump of the present utility model is used in vehicle backup, comprises stretching rod 1, one-way valve 8, sealed type piston 9, and the bottom of described stretching rod 1 is installed with described one-way valve. Directional valve 8; the sealed piston 9 is installed above the stretch rod 1; a support device 7 is arranged on the periphery of the stretch rod 1; an anti-slip handle of an air pump is installed in the center of the stretch rod 1 2; A connecting pipe 6 is provided under the anti-skid handle 2 of the air pump.

The lower end of the connecting pipe 6 is connected with an inflatable head 5; both ends of the inflatable head 5 are connected with the air transmission pipe 4; the sealed piston 9 is closely connected with the anti-skid handle 2 of the pump. The upper end of the one-way valve 8 is provided with pumping cylinders 3 which are distributed at both ends of the connecting pipe 6 ; a pressure changing device 10 is provided below the sealed piston 9 . The rear of the pumping cylinder 3 is provided with a pressure changing device 10; the front of the pumping cylinder 3 is provided with a stretching rod 1, and the stretching rod 1 can play a connecting role.

Working principle: The utility model has reasonable design and low production cost. The one-way valve is installed to save labor when pumping air, and the air in and out is smooth, and the pressure changing device can save labor.

It should be noted that the utility model is an inflator used for vehicle backup. Compared with the traditional inflator, there are more one-way valves. The function is to save manpower, because when the inflation head is inserted on the tire, the gas inside As the anti-slip handle of the pump is lifted, it will accumulate at the bottom of the pump cylinder, and if the handle is pressed down, it will waste energy.

Finally, it should be noted that: the above is only a preferred embodiment of the utility model, and is not intended to limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art , it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
