Since the staff forget to close the refrigerator after use, the cold air in the refrigerator is lost, causing the food in the refrigerator to contact the outside world, thereby reducing the storage effect of the refrigerator on food. At the same time, since the refrigerator is not closed for a long time, too much electricity is consumed in the refrigerator, thereby increasing the cost of refrigerating food in the refrigerator. Therefore, the existing self-locking refrigerator doors need to be improved to a certain extent. Utility Model Content

[0021] See also Figure 1-3 The utility model provides a technical solution: a self-locking refrigerator door, including a cabinet body 1, the outer wall of the cabinet body 1 is bolted to a first mounting plate 2, and the inner wall of the first mounting plate 2 is movably connected to an adjusting rod 3, the outer wall of the adjusting rod 3 is movably connected to a second mounting plate 4, and one side of the second mounting plate 4 is bolted to a protective door 5, one side of the second mounting plate 4 is fixedly connected to a positioning block 7, and the outer wall of the positioning block 7 is penetrated by a mounting groove 8.

[0023] The outer wall of the first mounting plate 2 is fixedly connected with a fixing frame 9, and the inner wall of the fixing frame 9 is penetrated and connected with an adjusting tube 10, the inner wall of the adjusting tube 10 is fixedly connected with a spring frame 11, and the other end of the spring frame 11 is fixedly connected with a clamping block 12, and the clamping block 12 forms a compression structure through the spring frame 11;
[0024] There are two blocks 12, and the two blocks 12 are symmetrically arranged with the mid-perpendicular line of the first mounting plate 2 as the symmetry axis. The outer wall of the block 12 is engaged with the mounting groove 8, and the inner wall of the block 12 matches the outer wall of the mounting groove 8 in shape and size.
[0025] The specific implementation method is as follows: by means of the reset spring 6, the positioning block 7 and the clamping block 12, a rotation adjustment method is adopted. At this time, the protective door 5 squeezes the reset spring 6 through the second mounting plate 4, so that the reset spring 6 rebounds later, completing the closure of the protective door 5 and the cabinet 1. At the same time, the positioning block 7 and the clamping block 12 are engaged to complete the positioning of the opening of the protective door 5.
[0026] This makes it convenient for the staff to open the protective door 5 according to the usage of the cabinet 1, and prevents the staff from forgetting to close the protective door 5, causing the refrigerator to be in contact with the outside world for a long time, thereby ensuring the stability of the refrigerator when closed and improving the effect of the refrigerator on storing food.
[0027] See also Figure 1-4 The utility model provides a technical solution: a self-locking refrigerator door, the outer wall of the protective door 5 is fixedly connected with a fixing plate 13, and one side of the fixing plate 13 is fixedly connected with a limiting rod 14, the outer wall of the cabinet body 1 is fixedly connected with a third mounting plate 15, and one side of the third mounting plate 15 is fixedly connected with a limiting plate 16, the inner wall of the limiting plate 16 is movably connected with a bearing rod 18, and the outer wall of the bearing rod 18 is fixedly connected with an adjusting block 19, and the top of the adjusting block 19 is fixedly connected with a push plate 21.
[0028] A first slot 17 is formed through the outer wall of the limit plate 16, and the inner wall of the first slot 17 is movably connected to the limit rod 14, and an adjustment block 19 is movably connected to the outer wall of the limit rod 14, and the adjustment block 19 forms a rotating structure with the bearing rod 18 through the limit rod 14;
[0029] A second slot 20 is formed through the outer wall of the adjusting block 19 , and the inner wall of the second slot 20 is engaged with the limiting rod 14 . The inner wall of the second slot 20 and the outer wall of the limiting rod 14 match each other in shape and size.
[0030] The specific implementation method is as follows: by setting the limit rod 14 and the adjustment block 19, a gravity adjustment method is adopted. When the fixing plate 13 drives the limit rod 14 to be adjusted through the protective door 5, the limit rod 14 pushes the adjustment block 19 so that the adjustment block 19 rotates along the bearing rod 18. When the limit rod 14 reaches the second slot 20, the adjustment block 19 descends by gravity to complete the limit of the limit rod 14.
[0031] This prevents the protective door 5 from rebounding after being closed with the cabinet body 1, thereby ensuring the refrigerator's ability to refrigerate the food inside. It also prevents the presence of a gap between the cabinet body 1 and the protective door 5, which would cause the loss of cold air inside the refrigerator, thereby reducing the cost of refrigerating food in the refrigerator.
[0032] Working principle: When the self-locking refrigerator door is used, when the staff needs to use the cabinet 1, first open the protective door 5, and then the protective door 5 drives the second mounting plate 4 installed on the outer wall to rotate along the adjusting rod 3, so that the second mounting plate 4 is adjusted with the first mounting plate 2 through the adjusting rod 3, thereby driving the second mounting plate 4 to push the reset spring 6, so that the reset spring 6 is compressed through the second mounting plate 4 and the first mounting plate 2, and the opening and closing of the protective door 5 is completed;
[0033] When the staff forgets to close the protective door 5, the No. 2 mounting plate 4 drives the protective door 5 to rotate along the adjusting rod 3 through the rebound of the reset spring 6, so that the protective door 5 drives the limiting rod 14 to be adjusted synchronously through the fixing plate 13 fixed to the outer wall. At this time, the limiting rod 14 slides along the No. 1 card slot 17 provided on the outer wall of the limiting plate 16, thereby driving the limiting rod 14 to push the adjusting block 19, and then driving the adjusting block 19 to rotate along the bearing rod 18;
[0034] When the limiting rod 14 moves to the No. 2 card slot 20 that penetrates the outer wall of the adjusting block 19, the adjusting block 19 rotates along the bearing rod 18 by gravity, so that the adjusting block 19 drives the No. 2 card slot 20 to engage with the limiting rod 14, and the protective door 5 and the cabinet 1 are closed. When the staff needs to open and close the protective door 5 for a long time, the positioning block 7 rotates through the No. 2 mounting plate 4, so that the outer wall of the positioning block 7 contacts the card block 12, thereby driving the card block 12 to compress the spring frame 11, and then driving the card block 12 to be compressed into the adjusting tube 10 through the spring frame 11;
[0035] When the installation groove 8 formed through the outer wall of the positioning block 7 moves to the clamping block 12, the extrusion exerted on the clamping block 12 and the spring frame 11 disappears, so that the spring frame 11 recovers its deformation, thereby driving the clamping block 12 to engage with the installation groove 8 formed through the outer wall of the positioning block 7, thereby completing the positioning of the second mounting plate 4 and the protective door 5, making it convenient for the staff to open the protective door 5 according to the usage of the cabinet 1.
[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
