Description

Technical Field

[0001] This utility model relates to a simple rebound slide rail. Background Technology

[0002] Chinese patent CN222853449U discloses a dual-function buffer and rebound mechanism for a drawer slide, comprising: an outer rail; a middle rail slidably connected to the outer rail; an inner rail slidably connected to the middle rail; a main body fixedly connected to the outer rail; a sliding plate slidably connected to the main body; a slider fixedly connected to the sliding plate; a toothed hook fixedly connected to the inner rail; and a rotating plate rotatably connected to the slider, wherein the rotating plate and the toothed hook are matched; a sliding hook is rotatably connected to the sliding plate, and a push block is slidably connected to the sliding plate, the push block abutting against the inner rail; when closing the drawer, the buffer allows the drawer to slide inward a certain distance and then slowly and automatically close, providing a silent and safe closing function; when the drawer rebounds and opens, pushing the inner rail inward again causes the drawer to automatically pop out, providing an automatic drawer opening function and eliminating the need for a handle. The advantage of this drawer slide is its dual function of buffering and rebounding, allowing the drawer to slide inward a certain distance and then slowly and automatically close, providing a silent and safe closing function; however, the product cost is very high, failing to meet the diverse consumption needs of consumers. Summary of the Invention

[0003] The purpose of this invention is to address the problem that existing slide rails cannot meet the multi-level consumption needs of consumers by providing a simple rebound slide rail with a simple structure and low cost.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A simple rebound slide rail includes an outer rail, a ball rail, and an inner rail. Balls are provided on the ball rail, and the inner and outer sides of the ball are in contact with the inner rail and the outer rail, respectively, so that the outer rail, the ball rail, and the inner rail can slide relative to each other.

[0006] A slide rail body is provided on the outer rail. The slide rail body includes a base, a slider, and a rotating plate. The slider is pushed and connected by a spring and slides on the base. The rotating plate is provided with a rotating shaft and a limiting post. The rotating plate is rotatably connected to the base through the rotating shaft.

[0007] The inner rail is fixed with a toothed hook, which has a locking tooth and a sliding groove that match the limiting post. When the toothed hook touches the limiting post of the rotating plate, the limiting post slides in the sliding groove and is hooked by the locking tooth, so that the inner rail is in a contracted state relative to the outer rail.

[0008] The inner rail is provided with a push block corresponding to the position of the slider. When the inner rail slides and retracts relative to the outer rail, the push block pushes the slider to compress the spring. When the locking teeth disengage from the limiting post of the rotating plate, the spring rebounds the push block, causing the inner rail to open relative to the outer rail.

[0009] The inner rail is connected to a rotatable fork, and the locking block on the fork matches the limiting block on the fixed outer rail to restrict the inner rail from detaching.

[0010] Preferably, the vane is provided with a guide shaft, and the vane is guided to rotate along the guide groove on the base by the guide shaft.

[0011] Preferably, the base is provided with a sliding rod that is telescopically extended by a tube spring, and the slider slides along the sliding rod in a specific direction.

[0012] Furthermore, the spring is mounted on the slide rod, and the slider is slidably mounted on the slide rod.

[0013] Furthermore, the pusher block is directly stamped from the inner rail.

[0014] The beneficial effects of this utility model are that, compared with the prior art which requires multiple damping rods, tension springs, and compression springs, this utility model only requires one rebound spring and does not require additional matching slides or sliders; therefore, the structure is simple and the cost is low, meeting consumers' demand for affordable and high-quality products.

[0015] The following embodiments, in conjunction with the accompanying drawings, further illustrate the present invention. Attached Figure Description

[0024] Reference Figures 1 to 7 This embodiment is a simplified rebound slide rail, including an outer rail 1, a ball rail 2, and an inner rail 3. Ball bearings 4 are mounted on the ball rail, with their inner and outer sides respectively contacting the inner and outer rails, allowing relative sliding between the outer rail, ball rail, and inner rail. A slide rail body is mounted on the outer rail, comprising a base 5, a slider 6, and a rotating plate 7. The slider is pushed and connected by a spring 8, allowing it to slide on the base. The rotating plate has a rotating shaft 9, a guide shaft 10, and a limiting post 11. The rotating plate is rotatably connected to the base via the rotating shaft, and guided to rotate along a guide groove 12 on the base via the guide shaft. A slide rod 20 is mounted on the base, with a spring fitted onto the slide rod, and the slider is slidably fitted onto the slide rod. The rod slides along the guide rail in a directional manner; the inner rail is fixed with a toothed hook 13, which has a locking tooth 14 and a sliding groove 15 that match the limiting post. When the toothed hook touches the limiting post of the rotating plate, the limiting post slides in the sliding groove and is hooked by the locking tooth, so that the inner rail is in a contracted state relative to the outer rail; the inner rail is stamped with a push block 16 corresponding to the position of the slider. When the inner rail slides and contracts relative to the outer rail, the push block pushes the slider to compress the spring; when the locking tooth disengages from the limiting post of the rotating plate, the spring rebounds the push block, so that the inner rail opens relative to the outer rail; the inner rail is connected with a rotatable fork 17, and the locking block 18 on the fork matches the limiting block 19 fixed on the outer rail to restrict the disengagement of the inner rail.

[0025] In use, the inner rail pusher pushes the slider on the base to compress the spring, causing the inner rail to slide and retract relative to the outer rail. When the toothed hook of the inner rail touches the limiting post of the rotating plate, the limiting post slides in the groove and is hooked by the locking teeth, so that the inner rail is in a retracted state relative to the outer rail, i.e., the drawer is closed. When the drawer is pushed, the inner rail pusher pushes the slider to compress the spring, the locking teeth of the toothed hook disengage from the limiting post of the rotating plate, and the spring rebounds the inner rail pusher, causing the inner rail to open relative to the outer rail, thus opening the drawer.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
