Detailed Description

The utility model is further described below with reference to the accompanying drawings.

In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

In the description of the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected, mechanically connected, electrically connected, directly connected, indirectly connected via an intervening medium, or connected internally of two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

The inflatable motor air tightness detection device comprises an air tightness detector 1 and an inflatable connecting assembly 2, wherein the inflatable connecting assembly 2 comprises a tube body 21 with thick ends and thin middle parts, the right end of the tube body 21 is provided with internal threads which are suitable for being in threaded connection with a detection tube of the air tightness detector 1, the middle part of the tube body is sleeved with an annular air bag 22, the annular air bag 22 is connected with a hose 23, the hose 23 is connected with an air valve 24, the air valve 24 is connected with a hand-held air adding bag 25, all or part of the annular air bag 22 can enter an air tightness detection port 31 of a motor 3 to be detected when the annular air bag 22 is not inflated, and the air tightness detection port 31 of the motor 3 to be detected can be completely blocked when the annular air bag 22 is inflated. The structure of thick parts at two ends and thin parts in the middle of the pipe body 21 can clamp the air bag, and the air bag is prevented from moving freely and falling off.

The thick portions at both ends of the tube body 21 are in arc transition with the thin portions in the middle, so that the annular air bag is prevented from being punctured.

The thick portion in right-hand member of body 21 is the hexagonal platform, does benefit to the spanner card and goes into, and convenient torsion installation also is favorable to the centre gripping fixed more.

The bag wall of the annular air bag 22 is connected with the pipe wall of the hose 23, and the bag cavity of the annular air bag 22 is communicated with the pipe cavity of the hose 23; the wall of the hand-held air-adding bag 25 is connected with the wall of the hose 23, and the cavity of the hand-held air-adding bag 25 is communicated with the lumen of the hose 23. The annular air bag 22 and the hand-held air bag 25 are made of high-quality rubber, and have good wear resistance, scratch resistance and pressure resistance.

The air valve 24 is not only a one-way valve and a stop valve, but also a safety valve, and the functions of one-way circulation and rotation stop of the air valve 24 are similar to those of the air valve used by a traditional sphygmomanometer, so that the description is omitted, but the air valve also has the function of the safety valve, and partial air can be automatically released when the air is excessively inflated or the pressure in the air bag exceeds a certain value, so that the air bag is prevented from being exploded.

During the use, insert the motor gas tightness detection mouth with the inflatable coupling assembling after gassing, adjust the suitable position that annular gasbag both sides exposed area size equals, use the hand-held type to add the gasbag and aerify in the annular gasbag, keep the pressure boost, until the gas bag that annular gasbag swelled wraps up completely and fills the gas tightness detection mouth of motor, the motor gas tightness detection mouth is blocked up completely to inflatable coupling assembling this moment, alright use the gas tightness detector to carry out the gas tightness test to the motor. After the test is finished, the air valve is opened to finish releasing the air pressure, the air tightness of the next motor is detected, the accuracy of the air tightness detection of the motor is improved, and the working efficiency is improved.

The present utility model is not described in detail in the prior art or common general knowledge in the art.
