[0001] The present application belongs to the field of furniture technology, and specifically relates to a slide rail device with a limiting structure. [Background technology]

[0002] Slide rail devices are commonly used in drawers, cabinet doors, etc. Traditional slide rail devices usually include a slide rail base fixed in the drawer, a sliding assembly slidably connected thereto, and a buffer assembly between the two. In order to achieve a buffering effect when the drawer is folded, it is necessary to set a release mechanism that can keep the slide rail base and the sliding assembly extended after the drawer is pulled out, and buffer the sliding assembly and the slide rail base through the buffer assembly after the drawer is pushed in. The release mechanism cooperates with the paddle connected to the drawer to switch the sliding assembly and the slide rail base between locking and unlocking. However, the paddle is currently easy to deviate to both sides when the drawer is pulled out, resulting in loose cooperation between the paddle and the release mechanism, affecting the stability of locking and unlocking.

[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] See also Figures 1 to 5 A slide rail device with a limiting structure includes a slide rail base 1, a sliding assembly 2 slidably connected to the slide rail base 1, a paddle 3 that slides along the length direction of the slide rail base 2 and is connected to a drawer, and a release mechanism 4 that cooperates with the paddle 3 to keep the slide rail base 1 locked or unlocked. The slide rail base 1 is provided with two limiting strips 5 for limiting the deviation of the paddle 3 along its width direction.

[0024] The present application discloses a slide rail device with a limiting structure, which can effectively limit the deviation of the paddle along its width direction by means of two limiting strips arranged on the sliding assembly, thereby ensuring good cooperation between the paddle and the release mechanism, improving the stability of the drawer sliding, and enhancing the reliability of the locking and unlocking functions.

[0025] Furthermore, as a preferred implementation mode of the present invention but not a limitation, the release mechanism 4 includes a release plate 41 movably arranged between the slide rail base 1 and the sliding assembly 2, the slide rail base 1 is provided with a guide groove 42, the paddle 3 is provided with an arc-shaped opening 43, the release plate 41 is provided with a guide column 44, the sliding assembly 2 is provided with a clearance groove 45 for the guide column 44 to pass through, one end of the guide column 44 is embedded in the guide groove 42, and the other end is stuck in the arc-shaped opening 43.

[0026] In this embodiment, the release piece is movably arranged between the slide rail base and the sliding assembly, and the precise guidance and stable movement of the release piece are ensured by the cooperation of the guide groove and the guide column. This enables a good locking and unlocking effect to be achieved when the drawer is pulled out and pushed in. The release piece cooperates with the arc-shaped opening of the paddle through the movement of the guide column in the guide groove, thereby achieving a stable locking and unlocking operation. This design is exquisite and concise, which not only improves the reliability and stability of the release mechanism, but also simplifies the manufacturing process and reduces the cost, while ensuring the efficient operation and long-term use of the slide rail device.

[0027] Furthermore, as a preferred embodiment of the present invention but not a limitation, the guide groove 42 includes a release section 421 arranged along the length direction of the slide rail base 1 and a locking section 422 arranged along the width direction of the slide rail base 1, and the release section 421 and the locking section 422 are arranged in sequence in the drawer pulling direction.

[0028] In this embodiment, the guide groove is divided into a release section and a locking section, and their arrangement enables the release piece to be released and locked in a specific order when the drawer is pulled out and pushed in. The design of the release section ensures the smooth opening of the drawer; and the locking section plays a role in locking the slide rail base and the sliding assembly when the drawer is pulled out, thereby ensuring a buffering effect.

[0029] Furthermore, as a preferred embodiment of the present invention but not a limitation, the arc-shaped opening 43 includes a first latching position 431 corresponding to the release section 421 and a second latching position 432 corresponding to the locking section 422. When the drawer is pulled out, the sliding assembly 2 slides in a direction away from the slide rail base 1. At this time, the guide column 44 slides along the release section 421 and engages with the first latching position 431. Subsequently, the guide column 44 slides into the locking section 422 under the joint action of the first latching position 431 and the locking section 422 and is pushed to the second latching position. The second locking position 432 is formed, and the paddle 3 is separated from the guide column 44, so that the sliding component 2 and the slide rail base 1 remain locked; when the drawer is pushed in, the sliding component 2 slides toward the slide rail base 1, and the guide column 44 slides into the second locking position 432 and slides along the locking section 422. Subsequently, the guide column 44 is pushed to the first locking position 431 and slides into the release section 421 under the joint action of the second locking position 432 and the locking section 422, so that the sliding component 2 and the slide rail base 1 are unlocked.

[0030] Further, as a preferred implementation manner of the present solution but not a limitation, the spacing distance between the two limiting strips 5 is adapted to the width of the paddle 3 .

[0031] In this embodiment, the paddle is prevented from excessively deflecting or swinging during the operation of the drawer. This precise adaptation can ensure that the cooperation between the paddle and the release mechanism remains stable and reliable, thereby enhancing the performance and durability of the slide rail device. At the same time, such a design can also reduce the possibility that the slide rail base and the sliding assembly cannot be locked normally due to unnecessary swinging or deflection, providing users with a more reliable use experience.

[0032] Further, as a preferred implementation of the present solution but not a limitation, a chamfer 51 is provided on the limiting strip 5 on the side of the direction away from the paddle 3 , and the chamfer 51 is gradually inclined inward from the direction away from the paddle 3 to the direction approaching the paddle 3 .

[0033] In this embodiment, the friction and resistance between the paddle and the limit strip can be effectively reduced, especially in the process of the paddle moving inward, so that the paddle can transition more smoothly when approaching the limit strip, reducing unnecessary vibration and impact, thereby improving the stability of the slide rail device and the smoothness of operation. In addition, the chamfer setting can also reduce the wear between the paddle and the limit strip, extend their service life, reduce noise and energy loss, and provide users with a quieter and smoother use experience.

[0034] Furthermore, as a preferred implementation manner of the present solution but not a limitation, a damper 6 is also included which is respectively connected to the slide rail base 1 and the sliding assembly 2 .

[0035] In this embodiment, the closing speed of the drawer can be effectively controlled, providing a more comfortable and advanced user experience. Through the action of the damper, the drawer can be gradually decelerated during the closing process, avoiding violent impact and noise, protecting the structure of the drawer and the slide rail device from damage, and reducing the risk of accidental pinching. When the drawer is opened, the damper can also control the speed of the drawer so that it can be pushed out smoothly, increasing the comfort of use.

[0036] Furthermore, as a preferred implementation manner of the present solution but not a limitation, it further includes a tension spring 7 respectively connecting the slide rail base 1 and the sliding assembly 2 .

[0037] In this embodiment, the tension spring can provide additional recovery assistance, making the drawer more stable and smooth when closing. This design can ensure that the drawer can be completely tightened when closing, avoiding the situation where the drawer is half-opened or half-closed due to external force or friction, keeping the furniture clean and beautiful, and increasing the convenience of use.

[0038] Furthermore, as a preferred implementation of the present solution but not a limitation, the guide groove 42 also includes a buffer section 423 , the locking section 422 is arranged between the release section 421 and the buffer section 423 , and the buffer section 423 gradually tilts upward in a direction away from the locking section 422 .

[0039] In this embodiment, the drawer can gradually slow down and stop with a buffer when being pulled out, effectively reducing the impact force and noise when the drawer is opened. The gradually upward tilted design of the buffer section can make the drawer transition to the buffer state more smoothly when close, reducing the swing and vibration of the drawer and improving the comfort of use.

[0040] The working principle of this embodiment is as follows:

[0041] The present application discloses a slide rail device with a limiting structure, which can effectively limit the deviation of the paddle along its width direction by means of two limiting strips arranged on the sliding assembly, thereby ensuring good cooperation between the paddle and the release mechanism, improving the stability of the drawer sliding, and enhancing the reliability of the locking and unlocking functions.
