In order to provide a better understanding of the present application, those skilled in the art will now make further details of the present application with reference to the drawings and detailed description. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The device for detecting the air tightness of the kit shown in fig. 1-5 comprises a kit body 1 and a drawer type unit 2.

An extraction opening is formed in one end face of the box body 1, an extraction pipe 11 used for being connected with an external vacuum pump is arranged at one end of the extraction opening, a square opening 12 is formed in the other end of the box body 1, a plurality of hanging frames 13 are arranged on the inner top wall of the box body 1, pressure sensors 14 are arranged at the lower ends of the hanging frames 13, and all the pressure sensors 14 are electrically and mechanically connected with the outside.

The drawer type unit 2 is slidably arranged in the box body 1, the drawer type unit 2 comprises a U-shaped part 21 matched with the square opening 12, a pair of sliding grooves 22 are formed in the inner walls of two side edges of the U-shaped part 21, a through groove 23 is formed in one end face of the U-shaped part 21, a grabbing handle 24 is further arranged on one end face of the U-shaped part 21, a chassis 25 is slidably arranged in the sliding grooves 22 in a matched mode, the chassis 25 penetrates through the through groove 23, the upper end face of the chassis 25 is a nylon thread gluing fiber face, a pull piece 26 is arranged at one end of the chassis 25, two limiting blocks 27 used for limiting the reagent box 3 are assembled on the upper end face of the chassis 25, the bottom end face of each limiting block 27 is a nylon thread gluing burr face, and a preset distance is arranged between the upper end face of the reagent box 3 and a sensing part of the pressure sensor 14 when the reagent box 3 is placed on the chassis 25, and specifically, the distance is 0.5 mm-3 mm.

The kit air tightness detection device not only can carry out air tightness detection in batches, but also can encase all qualified kits 3 in batches.

The specific working mode is as follows:

the number and arrangement of the reagent boxes 3 in each layer in the packaging box are determined first, in this embodiment, 3 rows of reagent boxes 3 are taken as an example in each layer in the packaging box, and 4 reagent boxes 3 are taken as an example in each row.

The drawer type unit 2 is taken out, and firstly, two limiting blocks 27 are stuck on the chassis 25, so that when the reagent boxes 3 are tightly attached to one side surface and one end surface in the U-shaped part 21 and discharged, the reagent boxes 3 in 3 rows and 4 columns can be just put down, and the arrangement mode of the reagent boxes 3 in one layer in the packaging box is consistent.
