Abstract

The utility model relates to an inflator for vehicles, which comprises a bottle body for a compressed body. A gas-pressure gage and a safety valve switch are arranged at a bottle opening, the safety valve switch is extended with a pipeline, the end of the pipeline is connected with an air supply nozzle which can be connected with a tyre for inflation, and a tyre pressure gage is also arranged on the air supply nozzle; a pressure bottle is filled with inert gas. The utility model has the advantages that not only a tyre can be quickly inflated, but also the amount of the inflation can be controlled, so that safety can be guaranteed.

Description

The portable type pump-up device

The utility model relates to the automobile-used equipment of inflating.

Because busy, the economic level of modern's life improves, therefore many people have the instruments of riding instead of walk such as vapour, locomotive, yet because these vehicle all utilize wheel to reach locomotor activity, so one and that pressure of tire takes place is not enough or when being punctured by foreign matter, will inflate or tire patching, the inflatable appliance that carries on the existing car is illustrated in figure 1 as a motor pumping and is provided via the electric power of Cigarette lighter, therefore has following shortcoming in the use:

Because the electric power that Cigarette lighter can provide is limited, make air compression with the pumping of power start motor and ability that wheel for inputting is lifted and little, and the speed of inflating that inflatable appliance can provide also is very slowly, because the speed of inflating is directly proportional with the air supply that motor can be exported, also promptly be directly proportional with the size of motor, but excessive motor pumping not only costs an arm and a leg but also weight is big, carrying is difficult for, and therefore, commonly using inflatable appliance is that its certain limitation is arranged in the use; Be to take into account inflatable appliance and the Cigarette lighter power supply all will just can be implemented under good state in use because commonly use inflatable appliance again, therefore easily the damage do not expected of generation and the factor that can't use, and also be difficult for improveing by commonly using in the structure for above-mentioned shortcoming problem.

Be to adopt outlet to be equipped with to adorn the appendix structure that compressed-air actuated steel cylinder connecting band gas is chewed in safety valve switch and the compression indicator now with another kind of portable pump-up device, but the deficiency of this structure is the degree of inflation of tire, need to control difficult grasp for the user that experience lacks by people's experience.

The purpose of this utility model provides a kind of light and can be fast and portable type pump-up device that safety be inflated.

The utility model is to realize like this, pump-up device comprises the compression body bottle, and bottleneck is provided with gas gauge and safety switch, and safety switch extends out a pipeline, the pipeline end connects again to be established one and can chew with the air feed that inflation of tire joins, and air feed is chewed and also is provided with a tire gauge.

Wherein, fill unreactable gas in the described pressure bottle.

The utility model has the advantages that, provided by the pressure gas in the compressed gas cylinder, and gaseous tension can be adjusted by safety switch, so under the situation of gaseous tension greater than tire pressure, tire can be carried out fast aeration in compressed gas cylinder.Not needing to rely on miscellaneous equipment more in use can implement separately, because the setting of tire pressure indicator gauge, not only can just right control charge air in operation, and comparatively easy, and also the gas in the bottle is unreactable gas, the degree of safety height.

The following drawings and embodiment will be described further technical characterictic of the present utility model:

Fig. 1 is a constructional drawing of commonly using pump-up device.

Fig. 2 is a constructional drawing of the present utility model.

Fig. 4 is another constructional drawing of the present utility model.

Element number and title contrast among the figure:

1...... compressed gas cylinder

2...... safety valve switch

21... compression indicator

3...... pipeline

4...... air feed is chewed

41... tire gauge

5...... tire

51... inflation is chewed

6...... quick coupling

Embodiment:

As shown in Figure 2, pump-up device comprises that one is filled with the compression body bottle 1 of unreactable gas, bottleneck is provided with gas gauge 21 and safety valve switch 2, the safety valve switch extends out a pipeline 3, pipeline 3 ends connect the air feed of establishing a tool tire gauge 41 again and chew 4, as shown in Figure 3, chew after 4 inflations that are connected tires 5 chew 51, fast tire 5 is reached gas filed effect by pressurized gas bottle 1 at air feed.

During enforcement, as shown in Figure 3, can earlier air feed be chewed 4 inflations that are connected on the tire 5 and chew 51 parts, open, control the delivery pressure of unreactable gas in the pressurized gas bottle 1 via the adjustment of safety valve switch 2, but impel the pressure gas at high speed to squeeze in the tire 5, and tire 5 in-to-ins wheels tire pressure can be obtained by the indication of tire gauge 41, and inflating of tire 5 can be finished under fast speed efficient.Pump-up device is in depositing car the time, can be by safety valve switch 2 during because of the pressure change that expands with heat and contract with cold, and the partial pressure of releasing automatically when hypertonia impels gas bottle 1 to maintain under the state of a safety and stability.

And for example shown in the figure; after the utility model pump-up device system connects the safety valve switch 2 of establishing tool compression indicator 21 by gas bottle 1; and extend the pipeline 3 that an end has quick coupling 6; as shown in Figure 4; after can being connected the vapour-pressure type hand tool by the quick coupling 6 of pump-up device; reaching hand tool is convenient for carrying; the purpose of use; the vapour-pressure type hand tool is commonly used in solution must connect the problem points that gas piping produced of establishing air compressor; commonly using vapour-pressure type hand tool (as ailing machine) all is to use via the gas piping guiding of air compressor; yet on construction ground under the excessive situation of area; the phenomenon of gas piping curtailment takes place through regular meeting; perhaps length is oversize and be entangled with because gas piping is continuous, and causes and trips the user of service in the construction site easily and meet accident.

Claims (2)

1, a kind of portable type pump-up device comprises the compression body bottle, bottleneck is provided with gas gauge and safety valve switch, safety switch extends out a pipeline, and the pipeline end connects again to be established one and can chew with the air feed that inflation of tire joins, and it is characterized in that: air feed is chewed and also is provided with a tire gauge.

2, portable type pump-up device according to claim 1 is characterized in that: described pressure bottle, interior filling unreactable gas.
