[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0014] like Figure 1 As shown, a fixture for detecting air tightness of a vacuum pump bracket comprises a fixture body 1, on the upper side of the fixture body 1 there is only an air pump 2 for inflating, one end of the air pump 2 extends outwardly from an air delivery pipe 3 for delivering gas, a pressure gauge 4 for detecting air tightness is arranged on the air delivery pipe 3, and two connecting pipes 5 for connecting the vacuum pump bracket are arranged at the lower end of the pressure gauge 4;

[0015] An upper clamp 6 and a lower clamp 7 are arranged below the clamp body 1 for clamping and keeping the vacuum pump bracket in a sealed state. A rubber pad 8 is arranged on the edge of the upper clamp 6 for filling the gap in the vacuum pump bracket, and a sealing ring 9 is arranged on the edge of the lower clamp 7 for wrapping the vacuum pump bracket.

[0016] When in use, place the vacuum pump bracket between the upper clamp 6 and the lower clamp 7. When the upper clamp 6 and the lower clamp 7 are closed, the rubber software cooperates with the sealing ring 9 to make the inside of the vacuum pump bracket in a sealed state. After inserting the connecting pipes 5 into the holes of the vacuum pump bracket respectively, turn on the air pump 2 to inflate the inside of the vacuum pump bracket. If the vacuum pump bracket is in a sealed state, a value will be displayed on the pressure gauge 4. If there are cracks on the vacuum pump bracket causing leakage, no value will be displayed on the pressure gauge 4.

[0017] In further detail, the upper end of the air pump 2 is provided with a control rod 10 which is the same as the control rod 10 of the clamp body 1.

[0018] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0019] Although the terminology is frequently used in this article, it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the present invention, including the clamp body 1, air pump 2, air pipe 3, pressure gauge 4, connecting pipe 5, upper clamp 6, lower clamp 7, rubber cushion 8, sealing ring 9, and control rod 10; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
