Abstract
The utility model discloses an automatic vehicle gas cap, an expansion joint which is connected with a car exhaust emission pipe is arranged at the bottom of a gas cap body, and a pressure regulating valve, a check valve and a vent valve are respectively arranged at two sides of the gas cap body. The automatic vehicle gas cap has the advantages that 1, the automatic vehicle gas cap is a practical device which is researched and developed for the situations needing to change a tire for an automobile tire under emergencies, in the device, the car exhaust emission pipe is connected with the automatic vehicle gas cap by the expansion joint, sufficient gas source is provided at the moment of starting the car, tail gas enters the gas cap through the pressure regulating valve (regulating the air pressure) and the check valve (regulating the air inlet direction), the tire can be changed when the car is jacked up after expansion, thereby being fast, convenient and effortless; 2, as the middle part of the gas cap body is a retractable folding structure, the automatic vehicle gas cap is convenient to store; and 3, the automatic vehicle gas cap has a light and handy structure, is convenient to maintain and is stable and reliable in the using process.
Description
Technical field:
The utility model belongs to a kind of vehicle maintenance and repair and uses device, particularly a kind of change, can be when servicing a car tire with the automobile-used automatic pneumatic jack of car body jack-up.
Background technology:
At present, when motor tire needed replacing, maintenance, jack was the thing of indispensability.Traditional jack great majority all are the fluid pressure type jacks, and the existence of hydraulic efficiency pressure system makes jack very heavy, not portable, in case and hydraulic efficiency pressure system produce fault, maintenance is trouble very.But not the common principle of the jack of hydraulic pressure is to advance with screw rod, and the weight of lifting is directly fallen on the screw rod, causes the inefficacy of screw rod easily.In addition, use this jack operation effort, poor safety performance.
Summary of the invention:
The purpose of the utility model just is to overcome the deficiency that exists in the above-mentioned prior art, and a kind of light and handy, simple in structure, easy to maintenance, reliable and stable automobile-used automatic pneumatic jack is provided.
As above design; The technical scheme of the utility model is: a kind of automobile-used automatic pneumatic jack; It is characterized in that: be provided with the expansion pipe that is connected with the motor vehicle exhaust emission pipe in the bottom of pneumatic jack body, pressure regulating valve, check valve and blow off valve be housed respectively in the both sides of pneumatic jack body.
The middle part of above-mentioned pneumatic jack body is the telescopic folding structure.
The utlity model has following advantage and good effect:
1, the utility model is in the time of need changing tire to the motor tire emergency case and a kind of utility unit of researching and developing; This device couples together motor vehicle exhaust emission pipeline and automatic pneumatic jack with expansion pipe; Car engine moment provides sufficient source of the gas, and tail gas gets into pneumatic jack through pressure valve (adjusting air pressure) and check valve (adjusting airintake direction), after the expansion with automobile jack-up; Can change tire, efficient and convenient leicht fallen D/A.
2, because the middle part of pneumatic jack body is the telescopic folding structure, therefore be convenient to deposit.
3, light and handy, easy to maintenance, the use of structure is stable, reliable.
Description of drawings:
Fig. 1 is the scheme drawing after gas is full of of the utility model.
Fig. 2 is the scheme drawing of the utility model after exhaust.
The specific embodiment:
As shown in the figure: a kind of automobile-used automatic pneumatic jack, be provided with the expansion pipe 2 that is connected with the motor vehicle exhaust emission pipe in the bottom of pneumatic jack body 1, pressure regulating valve, check valve 3 and blow off valve 4 are housed respectively on the pneumatic jack body.The middle part of above-mentioned pneumatic jack body is the telescopic folding structure.
The utility model in use; With expansion pipe motor vehicle exhaust emission pipeline and automatic pneumatic jack are coupled together earlier; Car engine moment provides sufficient source of the gas, and tail gas gets into pneumatic jack through pressure valve (adjusting air pressure) and check valve (adjusting airintake direction), after the expansion with automobile jack-up; Can change tire, (as shown in Figure 1).After finishing using, blow off valve bleeds off the intrinsic gas of pneumatic jack, and the pneumatic jack body is compressed (as shown in Figure 2).
Claims (2)
1. an automobile-used automatic pneumatic jack is characterized in that: be provided with the expansion pipe that is connected with the motor vehicle exhaust emission pipe in the bottom of pneumatic jack body, in the both sides of pneumatic jack body pressure regulating valve, check valve and blow off valve be housed respectively.
2. automobile-used automatic pneumatic jack according to claim 1 is characterized in that: the middle part of above-mentioned pneumatic jack body is the telescopic folding structure.
