In particular, the first connection portion of the product may be a rigid body portion of the product and the second connection portion may be a flexible portion such as a connection cord. Alternatively, the first connection portion of the product may be a first rigid portion of the product and the second connection portion of the product may be a second rigid portion of the product.

In the present embodiment, the product airtightness testing mechanism includes an upper jig 1 and a lower jig 2. Wherein, the upper jig 1 is square and made of rigid material. For example, the upper jig 1 may be made of stainless steel or aluminum material or other materials. The upper jig 1 is provided with a first jig groove which is opened downwards. The first jig groove is adapted in size to the structure of an upper sealing unit (described in detail below).

The lower jig 2 is also formed in a square shape, and is made of a rigid material. For example, the lower jig 2 may be made of stainless steel or aluminum material or other materials. The lower jig 2 is provided with a second jig groove which is opened downwards. The dimensions of the second jig groove are adapted to the structure of the lower closing unit 4 (described in detail below).

An upper sealing unit is arranged in the first jig groove of the upper jig 1. The upper sealing unit is made of an elastic material, so that the upper sealing unit is elastically arranged in the upper jig 1 in an interference manner. The upper closing unit may be made of rubber, for example. The upper sealing unit is a seamless square ring (round or special shape according to the product), and is vulcanized and formed in a mould, and the section of the upper sealing unit is near square. The whole installation, the positioning and the replacement are simple and convenient, the combination area is large, the sealing performance is strong, and the wear resistance is good.

Referring to fig. 2, the upper sealing unit includes a first upper body 11 having a substantially frame shape and a second upper body 12 protruding outward from a side wall of the first upper body 11, the first upper fitting groove 7 is penetratingly disposed on the first upper body 11, the second upper fitting groove 8 is downwardly open and disposed on the second upper body 12, and the first upper fitting groove 7 and the second upper fitting groove 8 are communicated with each other.
