Description

Technical Field

[0001] This utility model relates to the field of heavy-duty slide rail technology, specifically to a silent and buffered heavy-duty slide rail. Background Technology

[0002] Compared to steel slide rails, aluminum alloy slide rails are lighter, self-lubricating, and offer a more comfortable and quieter sliding experience. They are widely used in industries such as electronics, electrical appliances, machinery, transportation, aviation, and medical. Depending on the load capacity, they range from approximately 1 to 1000 kg. Aluminum alloy slide rails are divided into light-duty and heavy-duty types to meet different needs and application scenarios. For example, slide rails used in medical, aviation, and automotive applications, which involve movement, need to have a locking function to prevent the load from shifting on its own and to avoid safety accidents.

[0003] The existing technology has the following problems:

[0004] Existing heavy-duty slide rails, due to their large weight, generate significant inertial and impact forces during movement. If these forces are not effectively buffered and dispersed, they may lead to the following safety hazards:

[0005] Buffer structure failure: Due to the performance limitations of the buffer material or unreasonable design, when the slide rail is impacted, the buffer structure may not be able to effectively absorb energy, resulting in a violent collision at the end of the slide rail, which may damage the slide rail itself or adjacent structures.

[0006] Insufficient locking function: The existing locking function mainly relies on external latches. These latches may loosen or be damaged during long-term use or when subjected to vibration, failing to effectively secure the carrier and increasing the risk of the carrier shifting on its own.

[0007] Inconvenient to operate: The need for additional installation and use of latches not only increases the complexity of operation, but also increases maintenance costs and the labor intensity of operators. Utility Model Content

[0008] This invention provides a silent, buffered heavy-duty slide rail to solve the problems mentioned in the background art.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0010] A silent, buffered heavy-duty slide rail includes an outer rail, a middle rail slidably connected to the inner right side of the outer rail, an inner rail slidably connected to the inner side of the middle rail, a plurality of double-row steel balls fixedly connected to the inner surfaces of both the outer rail and the middle rail, and a buffer bracket fixedly connected to the inner left side of the outer rail.

[0011] The buffer bracket includes a connecting plate, which is fixedly connected to the inner left side of the outer rail. A connecting slide plate is slidably engaged with the top of the connecting plate. Top columns are fixedly connected to both the front and rear sides of the right end of the connecting slide plate. Dampers are fixedly connected to both the front and rear sides of the connecting plate. The right end of the damper is fixedly connected to the left side of the top column. A buffer spring is fixedly connected to the left side of the top column. The left side of the buffer spring is fixedly connected to the right side of the connecting plate. A self-locking component is provided on the top left side of the connecting slide plate.

[0012] A further improvement of this utility model is that the double-row steel balls include connecting rows, and several connecting rows are respectively fixedly connected to the inner sides of the outer rail and the middle rail. Solid steel balls are movably connected to the left and right sides inside the connecting rows.

[0013] A further improvement of this utility model is that a positioning plate is fixedly connected to the left end of the inner rail, and an arc-shaped slot that runs vertically through the middle of the positioning plate.

[0014] A further improvement of this utility model is that: a wide groove is provided on the top of the connecting plate, and a narrow groove is provided at the left end of the wide groove.

[0015] A further improvement of the present invention is that the self-locking component includes an arc-shaped slide groove, which is opened on the top left side of the connecting slide plate. A locking post is slidably connected to the inner surface of the arc-shaped slide groove, and the top end of the locking post extends into the interior of the arc-shaped slot.

[0016] A further improvement of this utility model is that: a rotating plate is fixedly connected to the bottom end of the locking pin, and a sliding pin is fixedly connected to the bottom right side of the rotating plate.

[0017] A further improvement of this utility model is that the sliding column is slidably connected inside the arc-shaped groove, and horizontal surfaces are provided on both the front and rear sides of the sliding column.

[0018] A further improvement of the present invention is that a support column is fixedly connected to the top right side of the rotating plate, the support column is rotatably connected to the inner side of the connecting slide plate, a spiral spring is fixedly connected to the outer surface of the support column, and the end of the spiral spring away from the support column is fixedly connected to the inner wall of the connecting slide plate.

[0019] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0020] 1. This utility model provides a silent and buffered heavy-duty drawer slide. Through the cooperation of the connecting strip, solid steel balls, connecting plate, connecting slide plate, top column, damper, and buffer spring, the connecting strip and solid steel balls assist in pushing and pulling when the heavy-duty drawer slides are in use. This makes the pushing and pulling of the middle rail and inner rail smoother, while reducing noise and achieving quiet use without disturbance. At the same time, the sliding of the middle rail will also squeeze the top column, which will squeeze the damper and buffer spring, reducing the impact force when the drawer is closed, achieving the effect of buffering and noise reduction, and making the use of the heavy-duty drawer slides more convenient.

[0021] 2. This utility model provides a silent, buffered heavy-duty drawer slide. Through the cooperation of a positioning plate, an arc-shaped groove, a wide slide groove, a narrow slide groove, a locking post, a rotating plate, a sliding post, a horizontal plane, a support post, and a spiral spring, when the drawer is closed, the positioning plate can press the locking post, allowing it to slide into the arc-shaped groove. This allows the rotating plate to rotate around the support post, causing the sliding post to rotate and slide into the narrow slide groove via the horizontal plane. The pressure between the inner wall of the narrow slide groove and the horizontal plane controls the angle of the rotating plate, thus positioning the locking post. By locking it inside the arc-shaped groove, the drawer slide is locked, automatically locking the drawer and preventing it from opening automatically, thus facilitating the use of heavy-duty drawer slides.

[0029] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0030] like Figure 1-3 As shown, this utility model provides a silent and buffered heavy-duty slide rail, including an outer rail 1, a middle rail 2 slidably connected to the inner right side of the outer rail 1, an inner rail 3 slidably connected to the inner side of the middle rail 2, a number of double-row steel balls 4 fixedly connected to the inner surfaces of the outer rail 1 and the middle rail 2, a buffer bracket 5 fixedly connected to the inner left side of the outer rail 1, the double-row steel balls 4 including connecting rows 41, a number of connecting rows 41 are respectively fixedly connected to the inner sides of the outer rail 1 and the middle rail 2, solid steel balls 42 are movably connected to the left and right sides of the inner side of the connecting rows 41, and a positioning plate 31 is fixedly connected to the left end of the inner rail 3, and an arc-shaped slot 32 that runs vertically through the middle of the positioning plate 31;

[0031] When using heavy-duty drawer slides, the three-section slides (outer rail 1, middle rail 2, and inner rail 3) can be fully extended to maximize drawer space. The connecting strip 41 and solid steel balls 42 assist in pushing and pulling, preventing rust over time. This makes the middle and inner rails slide more smoothly, reduces noise, and allows for quiet use without disturbing others. The positioning plate 31 facilitates self-locking of the guide rails, making the use of heavy-duty drawer slides even more convenient.

[0032] like Figure 4 As shown, this utility model provides a silent and buffered heavy-duty slide rail. The buffer bracket 5 includes a connecting plate 51, which is fixedly connected to the inner left side of the outer rail 1. A connecting slide plate 52 is slidably engaged with the top of the connecting plate 51. Top columns 53 are fixedly connected to the front and rear sides of the right end of the connecting slide plate 52. Dampers 54 are fixedly connected to the front and rear sides of the connecting plate 51. The right end of the damper 54 is fixedly connected to the left side of the top column 53. A buffer spring 55 is fixedly connected to the left side of the top column 53. The left side of the buffer spring 55 is fixedly connected to the right side of the connecting plate 51. A self-locking component 56 is provided on the top left side of the connecting slide plate 52.

[0033] By sliding the middle rail 2, the top column 53 can be pressed, which in turn can press the damper 54 and the buffer spring 55, reducing the impact force when the drawer closes, achieving the effect of buffering and noise reduction, making the use of heavy-duty slide rails more convenient. At the same time, the self-locking component 56 can lock the slide rail, thereby preventing the drawer from opening automatically, and will automatically lock when the drawer is closed to a certain position.

[0034] like Figure 5-6 As shown, this utility model provides a silent and buffered heavy-duty slide rail. A wide slide groove 511 is formed at the top of the connecting plate 51, and a narrow slide groove 512 is formed at the left end of the wide slide groove 511. The self-locking assembly 56 includes an arc-shaped slide groove 561, which is formed on the top left side of the connecting slide plate 52. A locking pin 562 is slidably connected to the inner surface of the arc-shaped slide groove 561. The top end of the locking pin 562 extends into the interior of the arc-shaped slot 32, and a rotating plate 563 is fixedly connected to the bottom end of the locking pin 562. A sliding column 564 is fixedly connected to the bottom right side of the moving plate 563. The sliding column 564 is slidably connected inside the arc-shaped slide groove 561. Horizontal surfaces 565 are provided on both the front and rear sides of the sliding column 564. A support column 566 is fixedly connected to the top right side of the rotating plate 563. The support column 566 is rotatably connected to the inner side of the connecting slide plate 52. A spiral spring 567 is fixedly connected to the outer surface of the support column 566. The end of the spiral spring 567 away from the support column 566 is fixedly connected to the inner wall of the connecting slide plate 52.

[0035] When the drawer is closed, the positioning plate 31 presses against the locking pin 562, allowing it to slide into the arc-shaped groove 32. This causes the rotating plate 563 to rotate around the support pin 566, compressing the spiral spring 567 and causing the sliding pin 564 to rotate. The horizontal plane 565 allows the sliding pin 564 to slide from the wide groove 511 into the narrow groove 512. The pressure between the inner wall of the narrow groove 512 and the horizontal plane 565 controls the angle of the rotating plate 563, thus positioning the locking pin 562. By locking it inside the arc-shaped groove 32, the drawer is automatically locked, preventing it from opening automatically and facilitating the use of heavy-duty drawer slides.

[0036] The working principle of this silent, buffered heavy-duty slide rail will be explained in detail below.

[0037] like Figure 1-6As shown, when using heavy-duty drawer slides, the three-section slide design (outer rail 1, middle rail 2, and inner rail 3) maximizes drawer space utilization. The connecting strip 41 and solid steel balls 42 assist in pushing and pulling, making the middle and inner rails slide more smoothly and reducing noise. Simultaneously, the middle rail 2 presses against the top post 53, which in turn presses against the damper 54 and the buffer spring 55, reducing the impact force when the drawer closes and achieving a buffering and noise reduction effect. At the same time, the positioning plate 31 presses against the locking post 562, making the lock... The fixed column 562 can slide into the interior of the arc-shaped slot 32, and the rotating plate 563 can rotate around the support column 566. At the same time, it compresses the spiral spring 567, which causes the sliding column 564 to rotate and slide from the wide slide groove 511 into the interior of the narrow slide groove 512. Through the compression between the inner wall of the narrow slide groove 512 and the horizontal surface 565, the locking column 562 can be tightly locked inside the arc-shaped slot 32, thereby locking the slide rail and realizing automatic locking of the drawer, making the drawer less likely to open automatically, which facilitates the use of heavy-duty slide rails.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
