[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

The shape of the mounting base 100 matches the shape of the chassis base 310, and the chassis base 310 is mounted on the outside of the mounting base 100. The pressure plate assembly 200 is connected to the mounting base 100 via a rotating shaft 410, allowing the pressure plate assembly 200 to rotate around the rotating shaft 410 toward the mounting base 100, thereby pressing the chassis base 310 and the chassis cover 320 between the mounting base 100 and the pressure plate assembly 200. The chassis base 310 has only one hole for use as an inflation port. Of course, in other preferred embodiments of this utility model, any number of inflation ports can be provided; however, for the sake of simplicity, it is preferred to provide only one.

[0019] For example, the pressure plate assembly 200 and the mounting base 100 are hinged to the rotatable shaft 410. The remaining holes 420 on the chassis base 310 can be plugged with rubber stoppers. Therefore, when the pressure plate assembly 200 rotates around the rotatable shaft 410 toward the mounting base 100, thereby pressing the chassis base 310 and the chassis cover 320 between the mounting base 100 and the pressure plate assembly 200, a sealed space is formed between the chassis base 310 and the chassis cover 320. At this time, it is only necessary to insert the air tightness tester's inflation tube through the inflation hole to perform air tightness testing. The entire test is convenient, low-cost, and will not damage the chassis housing. Moreover, the structure of the entire chassis air tightness testing fixture is simple and easy to manufacture.

[0020] Further as Figures 1-4 As shown, the mounting base 100 includes a mounting frame 110 and a chassis mounting bracket 120 mounted on the mounting frame 110. The chassis mounting bracket 120 includes a first mounting side plate 121, a second mounting side plate 122 extending from the mounting frame 110 toward the pressure plate assembly 200, and a mounting top plate 123 mounted on the top of the first mounting side plate 121 and the second mounting side plate 122.

The two ends of the third vertical pressure plate 250 are respectively fixed to the middle of the first horizontal pressure plate 210 and the second horizontal pressure plate 220. The first horizontal pressure plate 210 and the first vertical frame 112 are connected by a rotating shaft 410 so that the rectangular frame structure can rotate around the rotating shaft 410 toward the first vertical frame 112 until the second horizontal pressure plate 220 contacts the second vertical frame 113.

[0024] In this preferred embodiment, the mounting base 100 is composed of a mounting frame 110 and a chassis mounting bracket 120 mounted on the mounting frame 110.

Similarly, the pressure plate assembly 200 is a frame structure formed by a first horizontal pressure plate 210, a second horizontal pressure plate 220, a first vertical pressure plate 230, and a second vertical pressure plate 240. Therefore, the pressure plate assembly 200 is also constructed from multiple plates.

Rubber pads are provided on the sides of the first pressing block 260 and the second pressing block 270 facing the mounting base 100 to prevent damage to the outer casing of the chassis 300.

[0026] First fasteners 600 are respectively installed at both ends of the second horizontal pressure plate 220, and second fasteners 700 are respectively installed at both ends of the second vertical frame 113. When the second horizontal pressure plate 220 contacts the second vertical frame 113, the first fasteners 600 and the second fasteners 700 are facing each other and fastened together. Here, the first fasteners 600 and the second fasteners 700 can adopt any fastening structure known in the art, such as snap-fit ​​fastening.

[0027] In this preferred embodiment, the first fastening member 600 includes a fixing part 610, a handle part 620, and a fastening part 630.

When the handle part 620 rotates from a position perpendicular to the fastening part 630 to a position in line with the fastening part 630, the fastening part 630 is released from the two side walls of the fastening groove 710.

[0028] The fastening part 630 includes a horizontal segment 631, a first vertical segment 632, and a second vertical segment 633; ​​the first ends of the first vertical segment 632 and the second vertical segment 633 are respectively fixed to the two ends of the rotating shaft 640; the horizontal segment 631 connects the second ends of the first vertical segment 632 and the second vertical segment 633; ​​the fastening groove 710 is a U-shaped groove; the two side walls of the U-shaped groove are respectively provided with grooves 711 at the ends away from the second horizontal pressure plate 220, and the horizontal segment 631 is fastened in the grooves 711.

The chassis base 310 is installed on the outside of the mounting base 100, and the chassis cover 320 is installed on the chassis base 310. Then, the pressure plate assembly 200 is rotated toward the mounting base 100, thereby pressing the chassis base 310 and the chassis cover 320 between the mounting base 100 and the pressure plate assembly 200, and engaging the first fastening member 600 and the second fastening member 700. Subsequently, the holes on the chassis base 310 are plugged, leaving only one hole as an inflation port. The inflation tube of the air tightness tester is then inserted into the inflation port, and the air tightness tester is used to perform an air tightness test. Here, the use of an air tightness tester for air tightness testing is known to those skilled in the art and will not be described further.
