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.

[0024] Air tightness testing instruments, including

[0025] Profile 1 has a transverse groove 11, a longitudinal groove 12, and a screw groove 13; four of the profiles 1 are distributed at the four corners.

[0026] The housing 2 includes a front plate 21 and a rear plate 22, which are respectively inserted into the two transverse grooves 11 at both ends; a left plate 23 and a right plate 24, which are respectively inserted into the two longitudinal grooves 12 at both ends; a bottom plate 25 connected to the screw groove 13 by screws; and a top plate 26.

[0027] The quick-release cover 3 is detachably connected to the profile 1; the quick-release cover 3 is used to fix the top plate 26 on the profile 1 to restrict the top plate 26 from moving relative to the profile 1 in the vertical direction.

[0028] This utility model provides an airtightness testing instrument. By connecting the quick-release cover to the profile, the top plate is restricted to the profile, thereby completing the installation of the top plate. This process does not require screws, making it convenient to disassemble and install the top plate, reducing steps and increasing efficiency.

[0029] Furthermore, as a preferred embodiment of this solution and not a limitation, the top plate 26 is provided with a longitudinal limiting groove 27 for the insertion of the front plate 21 and the rear plate 22, and a transverse limiting groove 28 for the insertion of the left plate 23 and the right plate 24. During installation, the top plate can simultaneously fix the left plate, right plate, front plate, and rear plate.

[0030] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the quick-release cover 3 includes a cover body 31, a buckle 32 provided on the cover body 31, and a limiting part 33 for covering the top plate 26. Since the top plate is not easily disassembled by external forces, the limiting effect of the limiting part is sufficient.

[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, the profile 1 is provided with a cavity 14 and a locking hole 15 connecting the cavity 14 to the outside, the locking hole 15 for the buckle 32 to be inserted for fastening.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, the cover 31 is provided with a first support leg 34 and a second support leg 35 spaced apart. The first support leg 34 is used to abut against the inner wall of the cavity 14, and the buckle 32 is provided on the second support leg 35. This improves the firmness of the fastening.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the cover 31 is provided with a first reinforcing rib 36 connecting the cover 31 and the first support leg 34, and a second reinforcing rib 37 connecting the cover 31 and the second support leg 35. This improves the firmness of the fastening and the strength of the first and second supports leg, preventing loosening caused by repeated disassembly.

[0034] Furthermore, as a preferred embodiment of this solution, and not a limitation thereof, it also includes a base 4. The base plate 25 has screw holes 251, and the base 4 is used to fasten to the profile 1 and cover the screw holes 251. This effectively prevents screws from loosening, and in scenarios requiring repeated disassembly and installation, it can provide temporary fixation without the need for screws.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the profile 1 is provided with a snap hole 16, and the base 4 is provided with a third support leg 41 and a fourth support leg 42 spaced apart, and a bottom buckle 43 provided on the fourth support leg 42. The third support leg 41 is used to abut against the inner wall of the cavity 14, and the bottom buckle 43 is used to cooperate with the snap hole 16. The principle of the base is similar to that of the quick-release cover.

[0036] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
