DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described below by specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0017] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0018] See Figure 1-Figure 4As shown, this specific embodiment adopts the following technical scheme: it includes a refrigerator insulation box body 1, a compression refrigeration module 2, and a sealed door assembly 3; the sealed door assembly 3 includes a butterfly door 4, a limiting fixed panel 5, a sealing strip 1 6, a sealing strip 2 7, a push lock 8, and a door frame 9; a pair of butterfly doors 4 are movably connected in the middle reserved groove of the door frame 9, and the inner sides of the butterfly doors 4 are respectively fixed with sealing strips 1 6 and sealing strips 2 7 through the limiting fixed panel 5, the sealing strip 1 6 is distributed in a U-shaped structure, and the sealing strip 1 6 corresponds to the upper end of the inner tank of the refrigerator insulation box body 1; the sealing strip 2 7 is distributed in a straight line, and when the butterfly door 4 is closed, the two sealing strips 2 7 are squeezed and kept in contact to achieve the sealing of the connecting seam of the butterfly door 4.

[0019] Among them, the cross-section of the sealing strip 1 6 and the sealing strip 2 7 is a sideways U-shaped hook structure; the limiting fixing panel 5 and the butterfly door 4 are connected through a barbed plug-in column, and the upper edges of the sealing strip 1 6 and the sealing strip 2 7 are clamped and fixed between the two.

[0020] In addition, an inward-recessed lock groove 10 is provided at one end of the butterfly door 4, and the inward-recessed lock groove 10 cooperates with the push lock 8 on one side of the door frame 9 to achieve locking; a pair of elastic connecting shafts 11 are respectively provided at both ends of the butterfly door 4, and the elastic connecting shafts 11 are inserted into the inner side of the reserved groove of the door frame 9.

[0021] The working principle of this specific embodiment is as follows: when the butterfly door 4 remains in a closed state, the sealing strip 6 and the rear edge of the upper end of the inner liner of the refrigerator insulation box body 1 remain in cooperation, are deformed after being squeezed, and are filled between the butterfly door 4 and the inner liner of the refrigerator insulation box body 1 to form a tight sealing structure; the sealing strip 27 remains in a fitted state before the left and right butterfly doors 4 are closed; when they are completely closed, the sealing strips 27 on both sides fill in the door gap for sealing, so that the inner liner of the refrigerator insulation box body 1 is in a completely sealed state to prevent cold air from leaking out.
