Description

Technical Field

[0001] This utility model relates to the field of drawer slide technology, specifically to a slide with damping function. Background Technology

[0002] Damped slides are a type of slide rail that utilizes the cushioning properties of liquids to provide ideal noise reduction and buffering. They are often used in drawers and other furniture.

[0003] Damped drawer slides use hydraulic pressure to slow down the drawer as it closes to its final distance, reducing impact and creating a comfortable closing experience. Even when pushed forcefully, the drawer closes gently, ensuring a perfect and quiet movement.

[0004] The existing damping slide rails have insufficient length reduction and are unbalanced in extension and retraction, and need to be improved. Utility Model Content

[0009] The damping device includes a fixed base at one end of the outer slide rail, a movable component slidably mounted on the fixed base, a damping rod whose output end is fixedly connected to the movable component on the fixed base, a spring fixedly mounted on the movable component with one end fixedly connected to the movable component and the other end fixedly connected to the fixed base and symmetrically arranged, a movable buckle is hinged inside the movable component, the movable buckle has a protrusion that penetrates the movable component, and a sliding piece that cooperates with the protrusion is hinged on the inner slide rail.

[0010] As an improvement, the movable part is provided with a symmetrical elastic element that cooperates with the middle slide rail at one end.

[0011] As an improvement, the movable part is provided with a through hole to accommodate the protrusion and to drive the movable buckle to move.

[0012] As an improvement, the fixed base is provided with a first fixing member that can fix one end of the spring, and the movable part is provided with a second fixing member that can fix the other end of the spring.

[0013] As an improvement, the slide is provided with two notches that engage with the protrusion and can push the protrusion to move within the through hole.

[0014] (III) Beneficial Effects

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] Example 1

[0025] Combined with appendix Figure 1-4A slide rail with damping function includes an outer slide rail 1 installed on a cabinet. One end of the outer slide rail 1 is provided with a damping device 2, and the other end is provided with a middle slide rail 3 extending to the outside of the outer slide rail 1. An inner slide rail 4 extending to the outside of the middle slide rail 3 is provided inside the middle slide rail 3.

[0026] The damping device 2 includes a fixed base 5 located at one end of the outer slide rail 1. A movable member 6 is slidably mounted on the fixed base 5. A damping rod 7 with its output end fixedly connected to the movable member 6 is fixedly mounted on the fixed base 5. A spring 8 with one end fixedly connected to the movable member 6 and the other end fixedly connected to the fixed base 5 and symmetrically arranged is fixedly mounted on the movable member 6. A movable buckle 9 is hinged inside the movable member 6. A protrusion 10 is provided on the movable buckle 9 that passes through the movable member 6. A sliding piece 11 that cooperates with the protrusion 10 is hinged on the inner slide rail 4.

[0027] The slide rail is mounted on the cabinet body. The drawer is equipped with a bottom-supporting buckle connected to the inner slide rail 4. When the drawer is opened, the drawer moves the bottom-supporting buckle, which in turn moves the inner slide rail 4. The sliding piece 11 on the inner slide rail 4 pulls the damping device 2 to unfold, the damping rod 7 on the damping device 2 unfolds, and the spring 9 extends. After the inner slide rail 4 has moved a certain distance, the sliding piece 11 rotates and disengages from the movable buckle 9. The inner slide rail 4 slides outward in the middle slide rail 3. While the inner slide rail 4 is sliding, it also drives the middle slide rail 3 to slide outward in the outer slide rail, thus unfolding the slide rail. Repeating the above steps in reverse will retract the slide rail and close the drawer.

[0028] Example 2

[0029] Combined with appendix Figure 1 The movable part 6 is provided with a symmetrical elastic element 12 that cooperates with the middle slide rail 3 at one end. When the drawer is closed, the inner slide rail 4 slides and retracts in the middle slide rail 3, and the middle slide rail 3 slides and retracts in the outer slide rail 1. The middle slide rail 3 first contacts the elastic element 12, and the elastic element 12 can limit and buffer the movement of the middle slide rail 3.

[0030] The movable part 6 is provided with a through hole 13 that accommodates the protrusion 10 and can drive the movable buckle 9 to move.

[0031] The slide plate 11 is provided with a notch 16 that is pressed and engaged with the protrusion 10 and can push the protrusion 10 to move within the through hole 13. There are two notches 16.

[0032] When the slider 11 separates from the movable buckle 9, the notch 16 on the slider 11 pushes the movable buckle 9 to rotate, thereby causing the protrusion 10 to rotate and separate from the slider 11; when the slider 11 engages with the movable buckle 9, the slider 11 pushes the movable buckle 9 to rotate, thereby causing the protrusion 10 to rotate, and causing the notch 16 to engage with the protrusion 10.

[0033] The fixed base 5 is provided with a first fixing member 14 for fixing one end of the spring 8, and the movable member 6 is provided with a second fixing member 15 for fixing the other end of the spring 8.

[0034] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, alterations, deletions of some features, additions of features, or recombinations of features to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the innovative principles of the present invention shall still fall within the scope of the technical solutions of the present invention.
