Description

Technical Field

[0001] This utility model relates to the field of guide rails, specifically a new type of drawer guide rail. Background Technology

[0002] Drawer slides are devices made of metal with grooves or ridges that support, secure, and guide moving devices or equipment while reducing friction. The longitudinal grooves or ridges on the surface of the drawer slide guide guide and secure the drawer. Traditional drawer slides cannot withstand large loads, thus requiring a new type of drawer slide.

[0003] Existing patent document CN216494332U discloses a novel drawer slide, including a fixed slide rail and a movable slide rail. The movable slide rail is slidably mounted on the fixed slide rail, and the fixed slide rail has the same shape as the movable slide rail. This novel drawer slide, with its fixed slide rail having the same shape as the movable slide rail, reduces processing steps, saves production equipment, lowers production costs, and improves enterprise production efficiency, which is beneficial to the long-term development of the enterprise. However, when operating the CN216494332U technology, it is prone to bending and deformation when bearing heavy drawers, making it difficult to provide reliable support and posing a safety hazard. Therefore, a new type of drawer slide is urgently needed. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a new type of drawer slide to solve the problem that existing new drawer slides are prone to bending and deformation when bearing heavy drawers, making it difficult to provide reliable support and posing safety hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel drawer slide, comprising a drawer body, a panel body fixedly connected to one side of the drawer body, connectors fixedly connected to the outer walls of the drawer body, and an inner rail installed on one side of the connector.

[0006] The outer walls of the inner rails are all in contact with balls, the outer walls of the balls are fitted with limit frames, the inner walls of the limit frames are fitted with flat rollers, the outer walls of the flat rollers are in contact with the upper outer rail, and the lower end of the inner rails is fitted with a lower outer rail.

[0007] Preferably, the outer wall of the inner rail is in close contact with the outer wall of the ball, and the inner rail is configured with an "I" shape.

[0008] Preferably, the ball is movably connected to the limiting frame, and the inner wall of the limiting frame has an open design.

[0009] Preferably, the limiting frame is movably connected to the planar rollers, and the planar rollers are evenly spaced on the inner wall of the limiting frame.

[0010] Preferably, the upper outer rail and the lower outer rail are arranged in parallel, and the upper outer rail is arranged in a "C" shape.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses ball bearings to create a tight contact between the inner rail and the inner rail. The I-shaped structure of the inner rail, with its unique mechanical design, can evenly distribute the load to all parts of the rail body, has strong bending resistance, and is not easily deformed when bearing heavy objects. At the same time, the semi-circular structure of the upper and lower outer rails has a high structural advantage. The arc-shaped surface can effectively disperse the pressure and increase the contact area with the inner rail. When under force, the pressure can be evenly transmitted, further improving the load-bearing capacity. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The embodiments of this utility model will be described below based on its overall structure.

[0020] Please see Figure 1-4 A new type of drawer slide includes a drawer body 1, a panel body 2 fixedly connected to one side of the drawer body 1, connectors 3 fixedly connected to the outer wall of the drawer body 1, and an inner rail 4 installed on one side of the connector 3.

[0021] Please see Figure 1-4A novel drawer slide is described, in which the outer walls of the inner rail 4 are all abutted against ball bearings 5, and the outer walls of the inner rail 4 and the ball bearings 5 ​​are tightly fitted together. The inner rail 4 has an "I" shaped structure. A limit frame 6 is installed on the outer wall of the ball bearings 5, and the ball bearings 5 ​​are movably connected to the limit frame 6. The inner wall of the limit frame 6 has an open design, and flat rollers 7 are installed on the inner wall of the limit frame 6. The limit frame 6 and the flat rollers 7 are movably connected, and the flat rollers 7 are evenly spaced on the inner wall of the limit frame 6. The outer wall of the flat rollers 7 abuts against an upper outer rail 8, and a lower... The upper outer rail 8 and the lower outer rail 9 are set parallel to each other, and the upper outer rail 8 is set with a "C" shaped structure. The ball bearings 5 ​​are set to provide close contact with the inner rail 4. The I-shaped structure of the inner rail 4, with its unique mechanical design, can evenly distribute the load to all parts of the rail body, has strong bending resistance, and is not easily deformed when bearing heavy objects. At the same time, the semi-circular structure of the upper outer rail 8 and the lower outer rail 9 has a high structural advantage. The arc surface can effectively disperse the pressure and increase the contact area with the inner rail 4. When under force, the pressure can be evenly transmitted, further improving the load-bearing capacity.

[0022] Working principle: When in use, take out the device and place it in the designated position. Connect and fix the drawer body 1 to the connector 3, and then fix the lower outer rail 9 to the furniture panel. When the drawer body 1 and the panel body 2 are pulled, the inner rail 4 slides inside the upper outer rail 8 and the lower outer rail 9. The ball bearings 5 ​​on both sides of the limiting frame 6 and the flat rollers 7 support the inner rail 4 to reduce sliding friction. Finally, pull out the drawer body 1 and put items inside the drawer body 1. This completes the use of the device.
