Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which some, but not all embodiments of the utility model are shown.

Referring to fig. 1-6, the present utility model provides a technical solution: the heat-insulating door plate of the refrigerator comprises a first glass door 1, a second glass door 2 and a heat-insulating cover plate 3, wherein sliding rails 4 are arranged at two ends of the first glass door 1, the sliding rails 4 are in sliding connection with the first glass door 1, the sliding rails 4 are arranged below the first glass door and are in sliding connection with the second glass door 2, through holes 5 are formed in the first glass door 1 and the second glass door 2, sliding grooves 6 are formed in the side walls of the through holes 5, small doors 7 are in sliding connection with the sliding grooves 6, a baffle plate 8 is fixedly connected to the lower side of the small doors 7 of the first glass door 1 and the second glass door 2, first sealing strips 9 matched with the baffle plate 8 and the small doors 7 are respectively arranged, the heat-insulating cover plate 3 is arranged at one end of the sliding rails 4,

in this embodiment, when people need to take articles from the refrigerator, firstly, the first glass door 1 and the second glass door 2 are used for observing articles in the refrigerator body 12, after the articles are observed, the small door 7 is opened, then hands are stretched into the opening to take the articles, at this time, because the area of the small door 7 is smaller, the opened opening is smaller, the cold air loss speed is very slow to keep the internal temperature of the refrigerator, and in addition, the two small doors 7 are arranged to facilitate people to smoothly take articles at two ends of the refrigerator, so that people can be prevented from opening the first glass door 1 or the second glass door 2 by not taking the articles at the far end through one small door 7, the cold air loss is caused rapidly due to overlarge opening, and when people take the articles in the refrigerator for a long time or at night, the arranged heat insulation cover plate 3 can be covered, and thus, the better heat insulation effect can be achieved for the refrigerator. .

As shown in fig. 2, the top of the small door 7 is provided with a handle groove 10, in this embodiment, since the surface of the small door 7 is very smooth, people can easily slip when opening the small door 7 and cannot open, so that the small door needs to be opened smoothly by the design of the handle groove 10.

As shown in fig. 2-3, the first glass door 1 and the second glass door 2 are provided with a second sealing strip 11 which is matched, and in this embodiment, in order to prevent the cold air from flowing out from the gap between the first glass door 1 and the second glass door 2, the cold air is prevented from flowing out by the design of the second sealing strip 11.

As shown in fig. 1 and 3, the bottom of the sliding rail 4 is fixedly connected with the cabinet 12, in this embodiment, the sliding rail 4 is fixedly connected with the cabinet 12, so that the first glass door 1, the second glass door 2 and the heat insulation cover plate 3 are all located at the opening of the cabinet 12, so as to facilitate heat insulation in the cabinet 12.

As shown in fig. 3, the slide rail 4 is connected with the heat-insulating cover plate 3 through the hinge 13, in this embodiment, the heat-insulating cover plate 3 is connected through the hinge 13, so that the heat-insulating cover plate 3 is very simple to open and close, the heat-insulating cover plate 3 is always opened when the heat-insulating cover plate 3 is used in a refrigerator, and the heat-insulating cover plate 3 can be closed when the refrigerator is not taken from the cabinet body 12 for a long time or at night, so that a better heat-insulating effect can be achieved on the refrigerator.

As shown in fig. 1 and 5, the sliding rail 4 and the heat-insulating cover plate 3 are provided with a matched sealing ring 14, and in this embodiment, the sealing ring 14 can prevent cold air from flowing out of a gap between the sliding rail 4 and the heat-insulating cover plate 3.

Working principle: when in use, when people need to take articles from the cabinet body 12 of the refrigerator, firstly, the articles in the cabinet body 12 are observed through the first glass door 1 and the second glass door 2, after the articles are observed, the handle groove 10 on the small door 7 is pulled open by hands, and then the hands stretch into the opening to take the articles, at the moment, because the area of the small door 7 is smaller, the opening is smaller, the cold air loss speed is very slow so as to keep the internal temperature of the refrigerator, and in addition, the two small doors 7 are arranged so as to be convenient for people to smoothly take the articles at two ends of the refrigerator, the first glass door 1 or the second glass door 2 is prevented from being opened by people without taking the articles at the far end through one small door 7, thus the cold air is quickly lost due to overlarge opening, and the arranged heat insulation cover plate 3 can be covered when people can not take the articles in the refrigerator at night for a long time, and the better heat insulation effect can be achieved for the refrigerator.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the principles of the utility model, the scope of which is defined in the appended claims and their equivalents.
