Technical Field

[0001] This utility model relates to the field of drawer slide technology, specifically a buffer-closing drawer slide. Background Technology

[0002] Drawer slides are hardware components fixed to furniture cabinets for the movement of drawers or cabinet panels. Their main functions include: supporting the drawer (ensuring stability and load-bearing capacity during operation), smooth operation (high-quality slides provide a smooth sliding experience, reducing friction and making opening and closing easier), push-to-open functionality (some slides also feature a push-to-open function for user convenience), full-extension design (three-section drawer slides allow the drawer to be fully extended, making items inside easier to access and manage), and concealed design (concealed bottom-mounted slides are installed at the bottom of the drawer, invisible from the front and sides, enhancing aesthetics).

[0003] Drawer slides are needed during the installation and use of drawers. Currently available drawer slides, although they have springs inside and have a buffer closing function.

[0004] However, existing drawer slides use springs for soft closing, which is greatly affected by the lifespan of the springs. The springs may become fatigued due to long-term compression and release, requiring regular inspection and replacement, thus increasing maintenance costs. In addition, they are not quiet enough, producing some noise during sliding, which affects the user and is not conducive to long-term use. Therefore, a soft-closing drawer slide is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a buffer-closing drawer slide rail, which solves the problems of spring fatigue due to long-term compression and release, requiring regular inspection and replacement, thus increasing maintenance costs, poor noise reduction, and noise generated during sliding, which affects the user and is not conducive to long-term use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a buffer-closing drawer slide rail, comprising a fixed slide rail and a movable slide rail, wherein a buffer sliding component is provided on the outside of the fixed slide rail;

[0007] The buffer sliding assembly includes an air valve pipe fixedly connected inside the fixed slide rail. A piston push rod is slidably connected to the inner side of the air valve pipe. Air holes are provided at the top and bottom of the air valve pipe. A sliding groove is provided at the bottom of the fixed slide rail. Multiple silent pulleys are rotatably connected to the inner bottom wall and inner top wall of the sliding groove. A slider is fixedly connected to the bottom of the moving slide rail. Sliding parts are fixedly connected to the left and right sides of the slider.

[0008] Furthermore, there are two air valve pipes, which are symmetrically distributed on the left and right sides of the moving slide rail.

[0009] Furthermore, the end of the piston push rod away from the valve tube is fixedly connected to the outer side of the moving slide rail, and the outer diameter of the slider is smaller than the inner diameter of the sliding groove.

[0010] Furthermore, the sliding member is slidably connected to the silent pulley, and the movable slide rail is disposed inside the fixed slide rail.

[0011] Furthermore, a connecting plate is fixedly connected to the top of the movable slide rail, and the top of the connecting plate is provided with a threaded mounting hole.

[0012] Furthermore, the front and rear ends of the fixed slide rail are both fixedly connected to mounting plates, and the top of the mounting plates is provided with strip-shaped positioning grooves.

[0013] Furthermore, damping springs are fixedly connected to the left and right sides of the fixed slide rail, and protective plates are fixedly connected to the outer sides of the damping springs.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1 to 4 In this embodiment, a buffer closing drawer slide rail includes a fixed slide rail 1 and a movable slide rail 2. A buffer sliding component is provided on the outside of the fixed slide rail 1.

[0023] The buffer sliding assembly includes an air valve pipe 3 fixedly connected inside the fixed slide rail 1. A piston push rod 4 is slidably connected to the inner side of the air valve pipe 3. Air holes 5 are provided at the top and bottom of the air valve pipe 3. A sliding groove 6 is provided at the bottom of the fixed slide rail 1. Multiple silent pulleys 7 are rotatably connected to the inner bottom wall and inner top wall of the sliding groove 6. A slider 8 is fixedly connected to the bottom of the movable slide rail 2. Sliding parts 9 are fixedly connected to the left and right sides of the slider 8. In use, the drawer will cause the movable slide rail 2 to slide inside the fixed slide rail 1. During this process, as the movable slide rail 2 slides continuously, it can drive the piston push rod 4 to slide back and forth continuously inside the air valve pipe 3, thereby performing air extraction and exhaust. At the same time, the sliding groove 6 and the slider 8 are slidably limited, and the sliding parts 9 of the slider 8 are driven to slide continuously inside the multiple silent pulleys 7 to reduce the noise frequency generated during sliding.

[0024] When the drawer is closed, the gas inside the air valve pipe 3 will slowly be discharged from the air hole 5, thereby suppressing the force of the piston push rod 4 to push inward, forming a buffer effect. This allows the drawer to be pushed against the air valve pipe 3 before it is close to the end of the closing process, thus preventing the drawer from violently hitting the cabinet, reducing noise and extending the service life of the drawer, fixed slide 1 and movable slide 2.

[0025] It should be noted that there are two air valve pipes 3, which are symmetrically distributed on the left and right sides of the moving slide rail 2.

[0026] It should be understood that the end of the piston rod 4 away from the valve tube 3 is fixedly connected to the outside of the moving slide rail 2, and the outer diameter of the slider 8 is smaller than the inner diameter of the sliding groove 6.

[0027] Among them, the sliding component 9 is slidably connected to the silent pulley 7, the movable slide rail 2 is set inside the fixed slide rail 1, the top of the movable slide rail 2 is fixedly connected to the connecting plate 10, the top of the connecting plate 10 is provided with a threaded mounting hole 11, the front end and the rear end of the fixed slide rail 1 are both fixedly connected to the mounting plate 12, the top of the mounting plate 12 is provided with a strip-shaped positioning groove 13. By setting the connecting plate 10 and the mounting plate 12, it is convenient for workers to connect the cabinet and the drawer with bolts and nuts.

[0028] In addition, damping springs 14 are fixedly connected to the left and right sides of the fixed slide rail 1, and protective plates 15 are fixedly connected to the outside of the damping springs 14. By setting the damping springs 14 and the protective plates 15, the effect of elastic protection on the outside of the fixed slide rail 1 is achieved, thereby reducing the impact of external force collision on the fixed slide rail 1.

[0029] The working principle of the above embodiments is as follows:

[0030] During use, the drawer causes the movable slide rail 2 to slide inside the fixed slide rail 1. As the movable slide rail 2 slides continuously, it drives the piston push rod 4 to slide back and forth inside the air valve pipe 3, thereby performing air extraction and exhaust. At the same time, it causes the sliding groove 6 and the slider 8 to slide and limit, and drives the slider 8's sliding part 9 to slide continuously inside multiple silent pulleys 7 to reduce the noise frequency generated during sliding. When the drawer is closed, the gas inside the air valve pipe 3 will slowly be discharged from the air hole 5, thereby suppressing the force of the piston push rod 4 to push inward, forming a buffer effect. This allows the drawer to push against the air valve pipe 3 before approaching the closing end, thereby preventing the drawer from violently impacting the cabinet, reducing noise, and extending the service life of the drawer, fixed slide rail 1, and movable slide rail 2.
