PREFERRED EMBODIMENT

[0029] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. In the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments in the present application, all the other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the present application.

[0030] With reference to Figures 1-3 The present application provides a refrigerator test hole device, comprising: an outer sleeve 1 having an outer convex part 11 and an outer tube body part 12;

[0031] An inner sleeve 2 having an inner convex part 21 and an inner tube body part 22, the inner tube body part 22 is inserted and matched with the outer tube body part 12 to form a through cavity a;

[0032] A first plug 3 arranged at one end of the through cavity a; and

[0033] A second plug 4 arranged at the other end of the through cavity a.

[0034] In use, the outer sleeve 1 with the first plug 3 is penetrated outwards from the hole in the refrigerator, at the same time, the inner sleeve 2 with the second plug 4 is inserted inwards from the hole outside the refrigerator, so as to realize the insertion of the inner sleeve 2 and the outer sleeve 1; then the first plug 3 and the second plug 4 are respectively plugged into the inner hole of the outer sleeve 1 and the inner hole of the inner sleeve 2; when the test probe is needed, the first plug 3 and the second plug 4 are pulled out, the test probe is passed through the inner and outer ends of the inner sleeve 2, and then the plugs are plugged into the inner holes of the sleeves, so as to complete the installation and use.

[0035] In an embodiment, with reference to Figure 5 The outer surface of the inner tube body part 22 is provided with a concave-convex groove. In this embodiment, the concave-convex groove is arranged to increase the shrinkage when the inner sleeve 2 is inserted into the outer sleeve 1, so as to increase the adhesion and the airtightness.

[0036] In an embodiment, with reference to Figure 5 The outer surface of the first plug 3 and the second plug 4 is provided with a concave-convex groove. In this embodiment, the concave-convex groove is arranged to increase the adhesion and the airtightness with the inner wall of the inner sleeve 2.

[0037] In an embodiment, with reference to Figures 1-5 The first plug 3 and the second plug 4 are both connected with a sleeve ring 5, and the sleeve ring 5 is sleeved on the outer sleeve 1 and the inner sleeve 2 respectively. In this embodiment, the sleeve ring 5 is arranged to connect the plug and the sleeve, so as to effectively prevent the plug from being lost.
