[0003] In modern home life and various commercial storage scenarios, pull-out baskets, as a storage device that effectively improves space utilization and facilitates the access of items, are widely used in various cabinet structures such as kitchen cabinets, wardrobes, and storage cabinets. As people's storage needs continue to increase, the market's requirements for the functionality, practicality, and adaptability of pull-out baskets are also gradually rising.

[0004] During the on-site installation of pull-out baskets, various factors such as wall construction errors, cabinet processing precision deviations, and installer techniques often result in discrepancies between the actual installation dimensions and the design dimensions. Existing fixed-size pull-out baskets, lacking dimensional adjustment capabilities, cannot adapt to these installation dimensional deviations, leading to problems such as tilting and misalignment after installation. Tilting not only severely affects the basket's aesthetics but also significantly hinders its normal use. For example, it may cause jamming or jamming during sliding, and could even lead to items tipping over. Furthermore, prolonged use in a tilted position accelerates wear on the sliding components, shortening the basket's lifespan and causing considerable inconvenience for users. Utility Model Content

[0018] Reference Figures 1 to 10 The present application proposes an embodiment in which the height-adjustable pull-out basket includes: Cabinet 10, with a cabinet opening on the front; The upper basket rack 20 and the lower basket rack 30 are respectively installed in the cabinet 10 in a way that can slide back and forth, and the upper basket rack 20 is installed on the upper end of the lower basket rack 30 in a way that can slide up and down. The locking mechanism 40 is used to connect the upper basket frame 20 and the lower basket frame 30 to lock the upper basket frame 20 at the upper end of the lower basket frame 30.

[0019] The height-adjustable pull-out basket is installed on the cabinet body 10, with the front opening of the cabinet body 10 serving as the access channel for the basket. The upper basket rack 20 and lower basket rack 30, as the core storage carriers, both slide back and forth via a sliding structure to meet the needs of pulling out and pushing in items. Simultaneously, the upper basket rack 20 is mounted on top of the lower basket rack 30 via a sliding connection structure, allowing it to move up and down along the lower basket rack 30 to adjust the overall height. When the upper basket rack 20 reaches the target height, the locking mechanism 40 generates a fixing force, locking the relative positions of the upper basket rack 20 and lower basket rack 30 to prevent relative sliding during use.

[0020] If there is a dimensional error in the height direction of the cabinet 10 during installation, the error can be compensated by adjusting the height of the upper basket frame 20 to ensure that the pull-out basket is level after installation, avoid tilting or misalignment caused by size mismatch, and ensure smooth sliding of the pull-out basket.

[0021] Specifically, the upper basket support 20 includes at least two upper vertical tubes 21, and the lower basket support 30 includes two lower vertical tubes 31. The upper vertical tubes 21 are inserted into the lower vertical tubes 31 and can slide up and down inside them. The nested structure of the vertical tubes provides precise guidance for height adjustment, prevents left and right deviations during adjustment, and further ensures the levelness of the basket during installation and use.

[0022] Preferably, the width of the upper vertical tube 21 is smaller than the inner width of the lower vertical tube 31. When the upper vertical tube 21 is inserted into the lower vertical tube 31, a reasonable gap is formed between the left and right side walls of the upper and lower vertical tubes 21 and 31. In actual installation environments, the wall may be slightly tilted due to construction errors, causing the cabinet to not be completely vertical after installation. Since the outer width of the upper vertical tube 21 is smaller than the inner width of the lower vertical tube, the gap between them provides a certain amount of tilt adjustment space for the upper vertical tube. When the cabinet tilts with the wall, the upper vertical tube 21 can adaptively adjust the tilt angle within the lower vertical tube 31, ensuring that the upper basket rack always remains horizontal, avoiding the problem of the entire pull-out basket tilting and items being unstable due to wall tilt. Compared to a design with tightly fitted dimensions, this gap design significantly improves the adaptability of the pull-out basket to non-ideal installation environments, reduces installation rework caused by wall problems, and lowers installation difficulty and cost.

[0023] Based on the above, the locking mechanism 40 includes a fastener 41, a locking nut 42, and a locking tube 43. The upper vertical tube 21 has a slot 211 extending through its lower end on its front side. The lower vertical tube 31 has a first hole 311 at its upper front end. The locking tube 43 has inward flanges 431 on its left and right sides at its upper end. The locking tube 43 is placed on the upper end of the lower vertical tube 31 through the inward flanges 431. The locking tube 43 has a second hole 432 located in front of the first hole 311 on its front side. The locking tube 43 extends into the upper vertical tube 21. The locking part 433 of 1 is connected to one end of the connecting part 434 at its front side. One end of the connecting part 434 passes through the slot 211 and is connected to the locking tube 43. The locking part 433 is provided with a light hole 435 and a limiting hole 436 distributed on the rear side of the light hole 435 and matching the shape of the locking nut 42. The locking nut 42 is disposed in the slot 211. The fastener 41 passes through the first hole 311, the second hole 432 and the light hole 435 from front to back and is threadedly connected to the locking nut 42.

[0024] First, the locking tube 43 is placed on the upper end of the lower vertical tube 31 through the inward flange 431, and its locking part 433 extends into the interior of the upper vertical tube 21. At this time, the fastener 41 passes through the first hole 311 of the lower vertical tube 31, the second hole 432 of the locking tube 43, and the light hole 435 of the locking part 433 in sequence from front to back, and finally connects with the locking nut 42 in the slot 211 by thread. Then, the upper vertical tube 21 is inserted into the interior of the upper vertical tube 21, so that the connecting part 434 passes through the slot 211 of the upper vertical tube 21. The locking tube 43 is fixed to form a preliminary positioning. When the fastener 41 is tightened, the locking nut 42 cooperates with the limiting hole 436 of the locking part 433. The limiting hole 436 matches the shape of the locking nut 42 to prevent the locking nut 42 from rotating. The axial force of the fastener 41 causes the locking part 433 to deform, so that the locking tube 43 and the lower vertical tube 31 clamp the upper vertical tube 21 to achieve locking. When the fastener 41 is loosened, the upper vertical tube 21 can slide up and down along the lower vertical tube 31 to adjust its height.

[0025] The locking mechanism 40 provides a stable locking force, preventing the lock from loosening due to vibration or load during use, ensuring that the height of the basket rack 20 remains fixed and improving safety. Locking and unlocking can be achieved simply by tightening or loosening the fasteners 41, without the need for complicated tools, allowing users to quickly adjust the height and making the operation easy.

[0026] In this embodiment, the pull-out basket also includes an outer basket frame 50 and a linkage component 60. A cabinet door 90 that can open and close the cabinet opening is installed on the front side of the cabinet body 10. The outer basket frame 50 is installed on the side of the cabinet door near the cabinet opening. The linkage component 60 connects the upper basket frame 20 and the outer basket frame 50.

[0027] When the user opens the cabinet door, the cabinet door moves the outer basket frame 50 synchronously. The outer basket frame 50 drives the upper basket frame 20 to slide forward through the linkage component 60, such as a pull rod or gear transmission. When the cabinet door is closed, the outer basket frame 50 moves backward with the cabinet door, and pulls the upper basket frame 20 to slide backward synchronously through the linkage component 60, realizing the linkage between the cabinet door and the outer basket frame 50, and the upper basket frame 20 and lower basket frame 30 inside the cabinet body 10.

[0028] Preferably, the lower basket rack 30 is equipped with a stop buffer buckle 70 at its lower end, and the cabinet 10 is provided with a sliding door damping buffer 80 that cooperates with the stop buffer buckle 70.

[0029] The stop buffer buckle 70 installed at the lower end of the lower basket rack 30 is an elastic or damping component, and the sliding door damping buffer 80 inside the cabinet 10 is a matching damping structure. When the basket is pulled forward to its limit position, the stop buffer buckle 70 contacts the sliding door damping buffer 80, and the damping buffer generates a reverse damping force to slow down the sliding speed of the basket; when the basket is pushed back to the closed position, the two contacts again, and the damping effect prevents the basket from directly colliding with the cabinet 10, thus achieving buffering and stopping. The structure of the sliding door damping buffer 80 and the stop buffer buckle 70 is prior art in this application, and this application does not specifically limit their structure and working principle.

[0030] In this embodiment, the upper basket rack 20 is provided with a first roller assembly 22, the lower basket rack 30 is provided with a second roller assembly 32 at the lower middle part, the cabinet 10 is provided with a first guide rail 11 that cooperates with the first roller assembly 22, and a second guide rail 12 that cooperates with the second roller assembly 32.

[0031] The first roller assembly 22 on the upper basket rack 20 engages with the first guide rail 11 inside the cabinet 10, and the second roller assembly 32 at the lower center of the lower basket rack 30 engages with the second guide rail 12. When the basket slides back and forth, the first roller assembly 22 rolls along the first guide rail 11, and the second roller assembly 32 rolls along the second guide rail 12. Together, they provide guidance and support for the sliding of the basket, reducing friction during the sliding process. The upper basket rack 20 and the lower basket rack 30, respectively, engage with the guide rails through roller assemblies, which can evenly distribute the weight of the basket onto the guide rails, avoiding deformation caused by excessive local stress and extending the service life of the basket and the guide rails.

[0032] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
