Description

Technical Field

[0001] This invention relates to the field of brackets, specifically to a track assembly for a rotating pull-out basket cabinet. Background Technology

[0002] Rotating pull-out cabinets are commonly used for home storage and kitchen / bathroom organization. The extension and rotation of the pull-out baskets rely on a track assembly. Currently, most rotating pull-out cabinet tracks are ordinary multi-section slides, which can only complete the linear extension and retraction of the baskets. This has drawbacks: the lack of a synchronized locking mechanism makes it easy for the baskets to be accidentally closed while rotating around the axis, leading to collisions between the baskets and the cabinet, damaging both and resulting in extremely poor safety.

[0003] Therefore, we propose a track assembly for a rotating pull-out basket cabinet to solve the above problems. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a track assembly for a rotating pull-out basket cabinet.

[0005] This invention provides a track assembly for a rotating pull-out basket cabinet, comprising a multi-section rail. The outer rail of the multi-section rail is fixedly connected to the cabinet body of the rotating pull-out basket cabinet, and the inner rail of the multi-section rail is rotatably connected to the pull-out basket. A rack is fixed on the outer rail, and a synchronous shaft is rotatably connected to the inner rail. A gear that meshes with the rack is fixed on the synchronous shaft. A locking component for locking the synchronous shaft is installed on the inner rail. A drive block that cooperates with the locking component is installed at the bottom of the pull-out basket. The top and bottom inner walls of the cabinet body are both equipped with multi-section rails, and the bottom center of the pull-out basket is rotatably connected to the inner rail via a rotating shaft. Preferably, the locking assembly includes a U-shaped fixed rail fixed on the inner rail, a U-shaped sliding rail slidably connected to the inner side of the U-shaped fixed rail, a return spring installed between the U-shaped fixed rail and the U-shaped sliding rail, a limit block fixed at one end of the U-shaped sliding rail near the gear, a limit wheel fixed on the synchronous shaft, a locking groove with the limit block at an equal angle on the upper part of the limit wheel, a drive wheel installed on the U-shaped sliding rail, and a groove with a mating groove on the drive block. Preferably, the drive block is provided with symmetrical guide portions to facilitate the drive wheel sliding into the groove along the guide portions. Preferably, a mounting plate is fixed on the U-shaped sliding rail, and the drive wheel is rotatably connected to the mounting plate. Preferably, the U-shaped sliding rail is symmetrically fixed with fixing rods, and the U-shaped fixed rail is provided with waist-shaped holes on both sides, with the fixing rods disposed in the waist-shaped holes. Preferably, the ends of the two fixing rods are connected by a connecting plate to make the fixing rods more stable.

[0006] Preferably, the multi-section rail has at least two sections, which provides strong adaptability.

[0007] When the pull-out basket is flush with the cabinet, the drive wheel is in the groove, the return spring is stretched, the limit block is outside the lock groove, and the synchronous shaft is unrestrained. At this time, the pull-out basket can be stored in the cabinet. As the pull-out basket rotates relative to the cabinet along the pivot, the drive wheel disengages from the groove and is released from the drive block's restraint. During this disengagement, the U-shaped sliding rail moves towards the synchronous shaft under the action of the return spring, and the limit block moves into the lock groove, locking the synchronous shaft. This prevents the pull-out basket from colliding with the cabinet during storage.

[0008] Compared with related technologies, the present invention provides the following beneficial effects: The locking mechanism is linked to the drive block, automatically locking the synchronous shaft when the pull-out basket rotates, preventing it from being retracted and completely avoiding accidental collisions during rotation. It automatically unlocks when the pull-out basket is flush with the cabinet, without affecting normal storage. The gear and rack transmission ensures smooth and synchronized extension and retraction of the inner rail, without jamming or misalignment, enhancing the user experience. The multi-section rail design, with at least two sections, accommodates pull-out baskets of different sizes; the sliding engagement of the locking mechanism combined with spring reset ensures a stable structure and long service life.

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0012] Please refer to the following: Figures 1 to 8 A track assembly for a rotating pull-out basket cabinet, based on a multi-section track 1, is adapted to the dual functions of extension and rotation of the rotating pull-out basket cabinet, and achieves safety control through synchronous transmission and linkage locking.

[0013] Multi-section rails 1 are symmetrically installed on the top and bottom inner walls of cabinet 3. Each multi-section rail 1 has at least two sections, and the number of sections can be selected according to the size of the pull-out basket 5 to improve versatility.

[0014] The outer rail 2 of the multi-section rail 1 is fixed to the inner wall of the cabinet 3 by bolts, serving as a fixed support end; the inner rail 4 is the moving end, and the bottom center of the pull-out basket 5 is rotatably connected to the inner rail 4 through a rotating shaft, realizing the rotation of the pull-out basket 5 around the rotating shaft.

[0015] The outer rail 2 has a rack 6 fixed along its length, and the inner rail 4 is rotatably connected to the synchronous shaft 7 through a bearing. A gear 8 is fixedly sleeved on the synchronous shaft 7, and the gear 8 and the rack 6 are always meshed.

[0016] When the inner rail 4 extends and retracts along the outer rail 2, the gear 8 rolls along the rack 6, driving the synchronous shaft 7 to rotate synchronously, ensuring that the inner rail 4 extends and retracts smoothly without deviation, thus solving the problems of jamming and misalignment in traditional rails.

[0017] The locking component 9 is the core linkage component. The U-shaped fixed rail 11 is fixed on the inner rail 4, and the U-shaped sliding rail 12 is nested inside the U-shaped fixed rail 11 to form a sliding fit. A reset spring 13 is installed between the U-shaped fixed rail 11 and the U-shaped sliding rail 12 to provide reset power for the U-shaped sliding rail 12.

[0018] A limiting block 14 is fixed at one end of the U-shaped sliding rail 12 near the gear 8, and a limiting wheel 15 is fixed on the synchronous shaft 7. A locking groove 16 is opened at an equal angle on the outer circumference of the limiting wheel 15. The limiting block 14 and the locking groove 16 are inserted to lock the synchronous shaft 7.

[0019] The U-shaped sliding rail 12 is fixedly mounted on the mounting plate 20, and the drive wheel 17 is rotatably connected to the mounting plate 20 to reduce frictional wear with the drive block 10.

[0020] The drive block 10 is fixed to the bottom of the pull basket 5, and a groove 18 adapted to the drive wheel 17 is provided. Inclined guide parts 19 are provided on both sides to guide the drive wheel 17 to slide smoothly into the groove 18.

[0021] The U-shaped sliding rail 12 is symmetrically fixed with fixing rods 21 on both sides. The U-shaped fixed rail 11 has corresponding waist-shaped holes 22 on both sides. The fixing rods 21 slide through the waist-shaped holes 22. The ends of the two fixing rods 21 are connected by a connecting plate 23 to prevent shaking and ensure the linear sliding stability of the U-shaped sliding rail 12.

[0022] like Figure 7 The synchronous shaft 7 can be synchronously driven with the track assembly at the top of the cabinet 3 via a connecting rod.

[0023] Working principle Storage unlocked state When the pull-out basket 5 is flush with the cabinet body 3, the drive wheel 17 is engaged in the groove 18, the reset spring 13 is stretched, the limit block 14 is disengaged from the locking groove 16, the synchronous shaft 7 rotates freely, the inner rail 4 can extend and retract freely, and the pull-out basket 5 is stored normally.

[0024] Rotation lock state When the pull-out basket 5 rotates around the pivot, the drive block 10 rotates synchronously, and the drive wheel 17 disengages from the groove 18; the reset spring 13 rebounds, causing the U-shaped sliding rail 12 to slide towards the synchronous shaft 7, the limit block 14 inserts into the locking groove 16, the synchronous shaft 7 is locked, the gear 8 cannot rotate, the inner rail 4 cannot extend or retract, and the pull-out basket 5 cannot be stored to avoid collision.

[0025] Reset Switching When the pull-out basket 5 rotates back to the flush position, the guide part 19 guides the drive wheel 17 to slide into the groove 18, the reset spring 13 stretches, the limit block 14 disengages from the lock groove 16, the synchronous shaft 7 unlocks, and the storage function is restored.

[0026] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
