The utility model discloses a car pump has the pressure release function, can prevent that the pump from inflating excessively automobile tire, and special cap structure can the person of facilitating the use operate car pump under the environment of dark in addition.
Description
Technical field
The utility model relates to gas-filled pump field, specifically relates to a kind of automobile air pump.
Background technique
Automobile air pump is that a kind of running by internal motor carrys out work energized equipment.When bleeding, the valve of connecting vessels is washed open by the air pressure of air, and gas enters inflator, and when inflating in tire, valve is closed by the air pressure in inflator again, and gas just enters in tire.
The use that existing automobile air pump is using needs user to pay close attention to automobile air pump the moment, thus timely closing automobile gas-filled pump, prevent Tire over-inflation or infringement automobile air pump.This mode of operation wastes time and energy.Also there is gas-filled pump instrument this external night not easily to observe, circuit, gas ducting connect the shortcomings such as convenient not.

Further, described plug is also provided with locating column, is provided with through hole in the middle of described adjusting nut, described locating column is through described through hole.
Further, also comprise lamp holder and support, the front end of described support is provided with lamp holder installation position, and described lamp holder is arranged on described lamp holder installation position with dismountable form.
Further, described support is provided with power circuit, and described lamp holder is connected with described power circuit electricity by flexible wire.
Further, the upper end of described support is provided with handle and pressure gauge.
(3) beneficial effect
The utility model automobile air pump has decompression function, gas-filled pump can be prevented excessive to automobile tyre inflation, holder structure special in addition, person easy to use can operate automobile air pump in dark conditions.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the utility model automobile air pump;
Fig. 2 is the structural representation of pressure relief regulating device in the utility model automobile air pump.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
A kind of automobile inflating pump structure of the present utility model as depicted in figs. 1 and 2, the pressure relief regulating device 2 comprising inflator 1 and be arranged on inflator 1, described pressure relief regulating device 2 comprises shell 13, plug 8, spring 9 and adjusting nut 10, described adjusting nut 10 is rotatably mounted on one end of described shell 13, the other end of described shell 13 is connected with described inflator 1, plug 8 described in one termination of described spring 9, adjusting nut 10 described in another termination of described spring 9, described inflator 1 is provided with relief hole 12, and described relief hole 12 is positioned at the positive lower end of described plug 8.
During work, pressure on plug 8 can be acted on by Regulation spring 9 by rotating adjusting nut 10, thus regulate the vent pressure of pressure relief regulating device 2, make the pressure that vent pressure equals when automobile tire normally uses.When automobile tyre inflation is full of, now continue to use automobile air pump, then unnecessary gas is discharged by pressure relief regulating device 2, prevents automobile tyre inflation excessive.
As optimization, described plug 8 is also provided with locating column 11, is provided with through hole in the middle of described adjusting nut 10, described locating column 11 is through described through hole.Above structure is more conducive to the structural stability of plug 8.
On the other hand, the utility model automobile air pump also comprises lamp holder 6 and support, and the front end of described support is provided with lamp holder installation position 5, and described lamp holder 6 is arranged on described lamp holder installation position 5 with dismountable form.
Although existing automobile air pump is also provided with lamp holder, but its lamp holder is all the front end being fixedly mounted on support, this structure can facilitate the storage battery power taking of automobile air pump and gas tube to connect automobile tire, but but can not illuminate instrument panel, causes the problem of instrument panel reading inconvenience.The demountable structure of the utility model lamp holder can the perfect shortcoming solving the inconvenience of instrument panel reading.
Wherein, described support is provided with power circuit, and described lamp holder 6 is connected with described power circuit electricity by flexible wire.The upper end of described support is provided with handle 4 and pressure gauge 3.
The beneficial effects of the utility model: have decompression function, can prevent gas-filled pump excessive to automobile tyre inflation, holder structure special in addition, person easy to use can operate automobile air pump in dark conditions.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
