Abstract

The utility model provides a micro-leakage detecting tool of an automobile air condition and belongs to a tool used for automobile maintenance. The micro-leakage detecting tool of the automobile air condition is provided with a gas tube body communicating with a cylinder body having male threads or female threads. The cylinder body is also provided with a loading/unloading ridge. The gas tube is equipped with an air valve pin. The micro-leakage detecting tool of the automobile air condition can cooperate with tools such as a vacuum pump, a fluorine-filled high pressure gauge and the like to find a leakage position conveniently and accurately. The use effect is good. And the structure is simple and reasonable and the manufacturing cost is low.

Description

Instrument is surveyed in the little omission of a kind of air conditioning for automobiles

Technical field

The utility model provides a kind of auto repair to use instrument, the instrument of the little leakage location detection of especially a kind of air-conditioning.

Background technology

In the auto repair process, the affirmation at the little leakage of air-conditioning position is a difficult problem always.Though some leak hunting instruments are also arranged on the market, and result of use is all relatively poor, when causing some maintenance person to run into little leakage or whole pipeline is changed, perhaps a whole set of aircondition is disassembled in water and detect.In water, detect, not only bother, nor can find leakage point effectively.

Summary of the invention

The utility model technical matters to be solved is to provide the little omission of a kind of air conditioning for automobiles to survey instrument, to improve the convenience of little leakage location detection.

The utility model is achieved in that the little omission survey of a kind of air conditioning for automobiles instrument, and it has the inflation body and the cylindrical shell of band external thread or internal thread to be connected together, and has on the cylindrical shell and loads and unloads rib in addition, in the inflation body plunger is installed.

The instrument that adopts the little omission of air-conditioning of said structure to survey can be with vacuum pump, fill instrument such as fluorine high pressure gauge and cooperate, and finds leak site easily and accurately, and result of use is good, and simple and reasonable, low cost of manufacture.

Embodiment

The embodiment that provides below in conjunction with accompanying drawing explains the concrete structure of the utility model.

Shown in accompanying drawing, instrument is surveyed in the little omission of a kind of air conditioning for automobiles of the utility model, and it has the inflation body 5 and the cylindrical shell 1 of band external thread or internal thread to be connected together, and has on the cylindrical shell and loads and unloads rib 3 in addition, in the inflation body plunger 4 is installed.

The structure of plunger, install and use identical on mode and the bicycle, no longer detail.

During use, adopt the areal survey mode.With one section pipeline suspecting or parts, utilize this instrument with its two ends port closed.To fill the fluorine high pressure gauge and be connected on filling on the fluorine hole of pipeline or parts, the inflation body of inflating on some testing tools on hole and the two ends port of vacuum pump will be connected, squeeze into the gas of suitable pressure after, observe and fill the pressure decline rate that the fluorine high pressure gauge shows.If pressure does not descend, then this pipeline or parts do not have leakage position, detect another pipeline or parts with same procedure again.If pressure descends, explain that then this pipeline or parts have leakage.

When the port of certain pipeline or parts is internal thread, adopts Fig. 1, shown in Figure 3 have an externally threaded testing tool.When the port of certain pipeline or parts is external thread, adopt Fig. 2, the testing tool that has internal thread shown in Figure 4.Can select the testing tool of suitable size for use according to the size at the screw thread position of pipeline to be detected or parts.

On the inflation body external thread can be arranged, so that connect vacuum pump.Can there be cushion 2 in the barrel or the outside to improve sealing effectiveness.Loading and unloading rib 3 can be hexagon, so that use spanner to load and unload.

Claims

1. instrument is surveyed in the little omission of air conditioning for automobiles, it is characterized in that, it has the inflation body (5) and the cylindrical shell (1) of band external thread or internal thread to be connected together, and has on the cylindrical shell and loads and unloads rib (3) in addition, in the inflation body plunger (4) is installed.
