[0020] Example: Figure 1-5As shown, the anti-derailment structure of the sliding device includes a sliding device body 1 and a movable rail 2. The movable rail 2 is slidably mounted on the sliding device body 1. The sliding device body 1 includes a fixed rail 11 and a mounting plate 12 for mounting the sliding device body 1 on the drawer panel. The mounting plate 12 is mounted on the bottom of the fixed rail 11. The movable rail 2 is slidably mounted on the fixed rail 11. The movable rail 2 is provided with an anti-derailment component 3. The sliding device body 1 is provided with an anti-derailment plate 13 corresponding to the anti-derailment component 3. The anti-derailment component 3 is fastened to the anti-derailment plate 13. When the drawer is closed, the sliding device body 1 is closed. When the movable rail 1 slides on the sliding device body 1, the anti-detachment component 3 is slidably connected to the anti-detachment plate 13. The anti-detachment plate 13 is disposed on the side wall of the mounting plate 12 and / or the fixed rail 11 and is located at the end of the movable rail 2 that extends outward. The anti-detachment component 3 is arranged in a figure-7 shape or in a bracket shape. The structure of this application reduces the possibility of the movable rail detaching from the fixed rail when it slides on the fixed rail to the end of the fixed rail and tilts the part of the movable rail that extends outward from the fixed rail. This reduces the risk caused by derailment and improves the safety during use.

[0021] The anti-detachment component 3 includes a mounting plate 31 and an extension plate 32. The mounting plate 31 is mounted on the movable rail 2. One end of the extension plate 32 is connected to one end of the mounting plate 31, and the other end of the extension plate 32 extends toward the sliding device body 1. The anti-detachment component 3 includes a pulley 33, which is rotatably mounted on the extension plate 32 and located on the side of the extension plate 32 facing the sliding device body 1. The anti-detachment component 3 is fastened to the anti-detachment plate 13 by the pulley 33. The pulley makes the movable rail slide more smoothly.

[0022] The device includes a limiting plate 132, which is disposed on the sliding device body 1 and located at the end of the movable rail 2 that extends outward. When the movable rail 2 is slid until the anti-detachment component 3 abuts against the limiting plate 132, the movable rail 2 stops sliding. The anti-detachment plate 13 is horizontally disposed on the side wall of the sliding device body 1, and the limiting plate 132 is vertically disposed at one end of the anti-detachment plate 13. The limiting plate is used to limit the length of the movable rail extending outward from the fixed rail, which can reduce the possibility of the movable rail derailing.

[0023] One end of the limiting plate 132 is connected to one end of the anti-derailment plate 13, and a limiting space 131 corresponding to the movable rail 2 is formed between the limiting plate 132 and the anti-derailment plate 13, which can reduce the possibility of the movable rail derailing.

[0024] The device includes an inclined plate 133, one end of which is connected to the end of the anti-detachment plate 13 away from the limiting plate 132, and the other end of which extends upward from the anti-detachment plate 13 at an increasingly inclined angle. The inclined plate is designed to make it easy for the anti-detachment component to slide onto the main panel.

[0025] The extension plate 32 includes an upper connecting part 321, a folded edge part 322, and a lower connecting part 323. The upper connecting part 321, the folded edge part 322, and the lower connecting part 323 are connected in sequence. The folded edge part 322 protrudes from the upper connecting part 321 in a direction closer to or farther from the movable rail 2. The folded edge part 322 abuts against the movable rail 2. The extension plate 32 is U-shaped or V-shaped. The folded edge part can enhance the rigidity of the extension plate and make it less prone to breakage.

[0026] The extension plate 32 is provided with a mounting shaft 324, and the pulley 33 is provided with a mounting hole 330 corresponding to the mounting shaft 324. The pulley 33 is rotatably mounted on the extension plate 32 through the cooperation of the mounting hole 330 and the mounting shaft 324, so that the pulley can be rotatably mounted on the extension plate.

[0027] The extension plate 32 has one or more sets, and the multiple sets of extension plates 32 are respectively connected to both sides of the mounting plate 31. A clamping space 30 corresponding to the movable rail 2 is formed between the extension plate 32 and the mounting plate 31. The movable rail 2 is placed in the clamping space 30 so that the anti-detachment component 3 is assembled on the movable rail 2. The movable rail 2 is provided with a bent portion 21 corresponding to the folded edge portion 322. The folded edge portion 322 fits into the bent portion 21 so that the anti-detachment component can be assembled more stably on the movable rail, reducing the possibility of the anti-detachment component falling off during use.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
