Description

Technical Field

[0001] This utility model relates to the field of refrigerators, and in particular to a protective mechanism for air-cooled refrigerators. Background Technology

[0002] The principle of a frost-free refrigerator is to use air for cooling. When hot air flows through the built-in evaporator, heat exchange occurs directly between the high-temperature air and the low-temperature evaporator, causing the air temperature to drop. Simultaneously, cold air is blown into the refrigerator. Frost-free refrigerators lower the temperature through this continuous circulation. To better utilize the refrigerator's cooling space, the interior is usually divided into multiple storage compartments, each with drawers. These drawers slide along internal rails. When a drawer is full of food, during the retraction phase, the drawer's inner wall may collide with the refrigerator's inner wall due to inertia, potentially damaging the refrigerator's interior. Therefore, we designed a protective mechanism for frost-free refrigerators. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a protective mechanism for air-cooled refrigerators, which can effectively solve the problem that the interior of the existing refrigerator is divided into multiple storage spaces, and each storage space is equipped with a drawer. The drawer slides with the slide rail inside the refrigerator. When a lot of food is placed in the drawer, during the reset phase, due to inertia, the inner wall of the drawer will collide with the inner wall of the refrigerator, which will easily damage the inner wall of the refrigerator.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A protective mechanism for a frost-free refrigerator includes a cabinet and a door rotatably connected to the front of the cabinet, and further includes: A placement plate is located on the upper side inside the box, and multiple support plates are located on the lower side inside the box. The upper side of the support plates is movably connected to the drawer. It also includes a guide plate fixedly installed on the upper side of the support plate, the side wall of the guide plate slidingly engaging with the inner wall of the guide groove located on the lower side of the drawer bottom, and a movable plate movably connected to the support plate. When the drawer is installed in place, the inner wall of the guide groove will contact the movable plate and limit the drawer.

[0005] Preferably, it also includes inclined strips fixedly installed on both sides of the top surface of the drawer, and the bottom surface of the support plate is provided with an inclined groove. When the drawer is installed in place, the outer wall of the inclined strip overlaps with the inner wall of the inclined groove, and the inclined strip is made of rubber.

[0006] Preferably, the guide plate has a cavity inside, the movable plate slides with the inner wall of the cavity, and also includes through holes through the outer walls on both sides of the guide plate, with the cavity and the through holes maintaining communication.

[0007] Preferably, the upper end of the movable plate is fixedly connected to a first magnetic strip through the upper inner wall of the cavity, and a second magnetic strip is provided on the inner wall of the bottom of the drawer, located on one side of the guide groove, and the first magnetic strip and the second magnetic strip are magnetically attracted to each other.

[0008] Preferably, it also includes an overlapping groove formed on the outer wall of one side of the guide plate, so that when the drawer is installed, the inner wall of the overlapping groove overlaps with the outer wall of the second magnetic strip.

[0009] Preferably, it also includes an arc-shaped block fixedly installed on the lower outer wall of the guide groove, the arc-shaped block being made of rubber, and the arc-shaped block slidingly engaging with a snap-fit ​​groove located on the upper side of the guide plate.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This utility model, through the sliding fit between the guide plate and the guide groove, avoids damage to the refrigerator interior by the drawer during installation. At the same time, the overlapping relationship between the inner wall of the movable plate and the guide groove ensures that the drawer is fixed in position, reducing damage caused by contact between the drawer and the refrigerator interior due to inertia.

They are merely simplified descriptions for the convenience of describing this invention and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this invention.

[0017] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0018] See attached document Figure 1-4 As shown, a protective mechanism for a frost-free refrigerator includes a cabinet 100 and a door 110 rotatably connected to the front of the cabinet 100. It also includes a placement plate 200 located on the upper side inside the cabinet 100 and multiple support plates 300 located on the lower side inside the cabinet 100. The upper side of each support plate 300 is movably connected to a drawer 400. In this application, the cabinet 100 has a storage space. Multiple placement plates 200 are provided on the upper side of the storage space to divide it. Furthermore, multiple support plates 300 are provided at the lower part of the storage space, and drawers 400 are provided on the upper side of each support plate 300. The drawers 400 are also used for storing items.

[0019] Specifically, in this application, to facilitate the installation of drawer 400, a guide plate 310 is fixedly installed on the upper side of support plate 300. The side wall of guide plate 310 slides in cooperation with the inner wall of guide groove 401 located on the lower side of bottom surface of drawer 400. A movable plate 320 is also movably connected to support plate 300. When drawer 400 is installed, the inner wall of guide groove 401 contacts movable plate 320, limiting the drawer 400's position. Specifically, after drawer 400 is used, it can slide along the side wall of guide plate 310, facilitating installation by the sliding relationship between guide plate 310 and the inner wall of guide groove 401. Simultaneously, after installation, the inner wall of guide groove 401 is obstructed by the outer wall of support plate 300, preventing direct contact between the inner end of drawer 400 and the inner wall of cabinet 100, thus avoiding damage.

[0020] Furthermore, as one implementation, it also includes inclined strips 410 fixedly installed on both sides of the top surface of the drawer 400. The bottom surface of the support plate 300 is provided with an inclined groove 301. When the drawer 400 is installed in place, the outer wall of the inclined strip 410 overlaps with the inner wall of the inclined groove 301. The inclined strip 410 is made of rubber. Through the inclined strip 410 with its inclined structure and the inclined groove 301 on the bottom surface of the support plate 300, the inclined strip 410 will not contact the inner wall of the inclined groove 301 during the installation of the drawer 400. Only after the installation is completed will the outer wall of the inclined strip 410 overlap with the inner wall of the inclined groove 301, ensuring the fixation of the installation position of the drawer 400 and avoiding the problem of the drawer 400 being damaged due to direct contact with the inner wall of the box 100 due to inertia.

[0021] Furthermore, in this application, the guide plate 310 has a cavity 302 inside, and the movable plate 320 slides in cooperation with the inner wall of the cavity 302. It also includes through holes 313 penetrating the outer walls on both sides of the guide plate 310, maintaining communication between the cavity 302 and the through holes 313. A first magnetic strip 321 is fixedly connected to the upper end of the movable plate 320 through the upper inner wall of the cavity 302. A second magnetic strip 430 is provided on the bottom surface of the drawer 400, located on the inner wall of one side of the guide groove 401. The first magnetic strip 321 and the second magnetic strip 430 are magnetically attracted to each other. When the drawer 400 is about to be installed, the outer wall of the corresponding guide groove 401 will contact the outer wall of the movable plate 320, causing the movable plate 320 to press against the cavity 302. Combined with the communication between the cavity 302 and the through holes 313, the gas inside the cavity 302 will overflow from the through holes 313 and act on the outer wall of the guide groove 401, thus fixing the drawer 400.

[0022] Furthermore, this application also includes an overlapping groove 311 formed on the outer wall of one side of the guide plate 310. When the drawer 400 is installed, the inner wall of the overlapping groove 311 overlaps with the outer wall of the second magnetic strip 430. It also includes an arc-shaped block 420 fixedly installed on the lower outer wall of the guide groove 401. The arc-shaped block 420 is made of rubber, and it slides in conjunction with a snap-fit ​​groove 312 formed on the upper side of the guide plate 310. Through the rubber arc-shaped block 420 and the engagement relationship between the arc-shaped block 420 and the snap-fit ​​groove 312, when the drawer 400 is installed, the corresponding arc-shaped block 420 will be within the snap-fit ​​groove 312, achieving relative fixation of the drawer 400's position.

[0023] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
