Description

Technical Field

[0001] The utility model relates to the technical field of drawers, and particularly relates to a freezing drawer structure for the interior of a refrigerator. Background Technique

[0002] Refrigerators are commonly used refrigeration equipment in households and commercial places, usually used to store food and keep it fresh. The internal structure of a refrigerator includes multiple drawers, which are used to store food separately and prevent cross-contamination between foods. Among them, the freezing drawer is a component in the freezer compartment of the refrigerator for freezing food.

[0003] In the current design of freezing drawers, many existing problems have not been effectively solved. For example, in the utility model with the patent number CN217179025U, although this design improves the sorting efficiency by separating foods, during use, the drawer on the right side is often difficult to open due to being blocked by the refrigerator door, which undoubtedly increases the difficulty of taking food. In addition, these drawers are directly placed inside the refrigerator and are often frozen due to the formation of ice, further causing the drawers to be difficult to pull out smoothly.

On the side of the third guide rail 5, a number of stop bars 16 are provided. On one side of the stop bars 16, a number of rollers 17 are arranged inside the third guide rail 5. Next to the rollers 17, a third stop block 15 is provided at one end of the third guide rail 5. Inside the second guide rail 3, a second fixing bar 20 is provided. At the top and bottom of the second fixing bar 20, slide rails 19 are provided. On both opposite sides of the lower drawer 4, side plates 7 are provided. On one side of each side plate 7 close to the lower drawer 4, a first guide rail 8 is provided. Inside each first guide rail 8, a number of balls 11 are arranged. The number of balls 11 is divided into two groups, and each group of balls 11 is clamped inside a clamping block 12. Between the clamping blocks 12, a first fixing bar 10 is provided. Between the first fixing bars 10, an upper drawer 2 is provided. The first guide rail 8 and the first fixing bar 10 cooperate with each other to assist the sliding of the upper drawer 2.

[0024] Further, on one side of the second fixing bar 20 close to the second guide rail 3, a groove 21 is opened, and a number of slide rails 19 provided on the second fixing bar 20 are attached to a number of second sliding grooves 22 opened inside the second guide rail 3. The groove 21 prevents the second fixing bar 20 from being overly attached to the second guide rail 3 and being frozen together. The second sliding grooves 22 and the second fixing bar 20 cooperate with the slide rails 19 to assist the movement of the upper drawer 2.

[0025] Further, on one side of the side plate 7 away from the lower drawer 4, a pulling groove 6 is provided for pulling the drawer.

[0026] Further, the second fixing bar 20 and a number of rollers 17 are both fixed on both sides of the lower drawer 4, and the second guide rail 3 and the third guide rail 5 are both fixed on the refrigerator body 1 to prevent the second guide rail 3 and the third guide rail 5 from moving along with the lower drawer 4 when the lower drawer 4 is pulled.

[0027] Further, at one end of the first guide rail 8, a second stop block 14 is provided, and at the end of the first guide rail 8 away from the second stop block 14, a first stop block 9 is provided. The first stop block 9 cooperates with the second stop block 14 to limit the moving distance of the balls 11 and the clamping blocks 12.

[0029] Working principle: When in use, the device first pulls the side plate 7 through the slot 6, thereby pulling the lower drawer 4. While pulling the lower drawer 4, a number of rollers 17 located in the third guide rail 5 start to rotate to assist the movement of the lower drawer 4. At the same time, the second fixing strips 20 fixed on both sides of the lower drawer 4 cooperate with the second guide rail 3 to reduce the pressure of the lower drawer 4 on the rollers 17, preventing the rollers 17 from being damaged when the drawer is loaded with heavy food. The fourth stop block 18 located at one end of the slide rail 19 is used to limit the sliding distance of the slide rail 19, preventing the slide rail 19 and the rollers 17 from sliding out of the second guide rail 3 and the third guide rail 5.

[0030] After pulling out the lower drawer 4, the upper drawer 2 can be pulled. While pulling the upper drawer 2, a number of balls 11 located on the first fixing strip 10 start to rotate. The provided catch block 12, while moving along with the balls 11, also restricts the position of the balls 11, preventing the balls 11 from rolling randomly. The second stop block 14 is used to hinder the continuous movement of the balls 11, preventing the balls 11 from sliding out between the first guide rail 8 and the first fixing strip 10.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
