AI Technical Summary
The refrigerator drawer rollers make a collision noise when closing due to excessive gap between themselves and the guide rails.
A refrigerator drawer roller was designed. By setting a groove and a pressure plate structure connected by a spring on the roller body, the spring pushes the connecting column to drive the pressure plate to contact the guide rail, thereby reducing the gap between the roller and the guide rail.
It effectively reduces the collision noise between the rollers and the guide rails when closing the drawer, improving the user experience.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of roller technology, specifically a roller for a refrigerator drawer. Background Technology
[0002] Rollers are generally cylindrical, rotatable objects. In mechanics, they are often driven by a power source (such as an electric motor) to move other materials forward or to generate pressure to process materials. Rollers come in various types and have a wide range of uses. Refrigerator drawer rollers are an important component of the refrigerator drawer sliding system, allowing drawers to slide easily inside the refrigerator for convenient access to food and beverages.
[0003] However, the roller structure may produce collision noise when closing the drawer, which is usually caused by excessive gap between the roller and the guide rail. Therefore, a roller for refrigerator drawers is proposed to overcome the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a roller for a refrigerator drawer. By placing the roller on the guide rail and then using a spring to push the connecting column to drive the pressure plate to contact the guide rail, the gap between the roller body and the guide rail is reduced, thus solving the problem that the roller structure may generate collision noise when closing the drawer due to excessive gap between the roller and the guide rail.
[0005] This utility model is achieved through the following technical solution:
[0006] This utility model is a roller for a refrigerator drawer, including a roller body with a groove on the outside of the roller body; mounting holes are evenly distributed on the bottom end of the groove, a spring is provided inside the groove, one end of the spring is connected to a connecting post, and a pressure plate is provided at the top of the connecting post; a roller bearing is provided on the inner side of the roller body, and a bolt is provided on one side of the roller bearing.
[0007] Furthermore, both ends of the pressure plate are designed with arc-shaped structures.
[0008] Furthermore, the pressure plate is designed as an arc-shaped structure.
[0009] Furthermore, the included angle between the two mounting holes and the axis of the roller body is both degrees.
[0010] Furthermore, the mounting holes are designed as circular holes.
[0011] Furthermore, the height of the pressure plate is located in the middle layer inside the groove, allowing for movement.
[0012] This utility model has the following beneficial effects:
[0013] This invention solves the problem of potential collision noise caused by excessive gap between the roller and the guide rail when closing the drawer due to the roller structure. By placing the roller on the guide rail and then using a spring to push the connecting column to drive the pressure plate to contact the guide rail, the gap between the roller and the guide rail is reduced.
[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4This utility model provides a technical solution: a refrigerator drawer roller, including a roller body 3. A groove 301 is formed on the outside of the roller body 3, allowing the roller body 3 to better fit onto the guide rail. Mounting holes 302 are evenly distributed at the bottom end of the groove 301. The mounting holes 302 are circular, and the included angle between the two mounting holes 302 and the axis of the roller body 3 is 30 degrees. A spring 4 is installed inside the groove 301. Under pressure, the spring 4 can retract. One end of the spring 4 is connected to a connecting post 501. When the spring 4 retracts and generates elastic force, it pushes the connecting post 501, causing a pressure plate 5 to fit against the guide rail. The top of the roller 1 is equipped with a pressure plate 5. The pressure plate 5 is made of a flexible and soft material, which allows the pressure plate 5 to fit well on the guide rail, reducing the gap between the roller and the guide rail. The pressure plate 5 is designed as an arc structure, with both ends of the pressure plate 5 being arc-shaped structures. The height of the pressure plate 5 is located in the middle layer inside the groove 301, providing movable space for pressing and moving the pressure plate 5. The inner side of the roller body 3 is equipped with a roller bearing 1, and a bolt 2 is provided on one side of the roller bearing 1. The roller is installed at the bottom of the refrigerator drawer by the bolt 2, and then installed on the guide rail, allowing it to move. When the refrigerator drawer is pulled, the roller bearing 1 drives the roller body 3 to rotate, thereby moving the refrigerator drawer and pulling it out.
[0022] By placing the roller on the guide rail, and then using the spring 4 to push the connecting column 501 to drive the pressure plate 5 to contact the guide rail, the gap between the roller body 3 and the guide rail is reduced, thus solving the problem of collision noise that may occur when closing the drawer due to excessive gap between the roller and the guide rail.
[0023] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
