Description

Technical Field

[0001] This utility model relates to a lifting cabinet, specifically an internal cabinet adjustment structure for a lifting cabinet. Background Technology

[0002] To maximize the use of vertical space, modern furniture often incorporates lift-up cabinets mounted on higher walls to allow sufficient room for lifting and lowering. Traditional lift-up cabinets are typically fixed directly to the interior of the cabinet via electric sliding rails. The installation method between the inner cabinet and the main cabinet is relatively simple, and the installation gaps between them cannot be adjusted. This necessitates extremely precise fit between components during assembly to ensure smooth and coordinated lifting. If there are dimensional deviations between the inner cabinet and the lifting mechanism exceeding the allowable range, assembly becomes difficult, potentially leading to jamming, shaking, or even misalignment during lifting, severely impacting the cabinet's usability. Large installation deviations result in accumulated friction and wear between components during repeated lifting movements, leading to instability and loosening of connections in later use. Furthermore, the inability to adjust installation gaps after assembly, coupled with material aging and normal wear, necessitates maintenance and replacement. This high maintenance difficulty and cost further hinders the widespread adoption of lift-up cabinets and reduces their competitiveness. Utility Model Content

[0004] The purpose of this utility model is achieved in the following way: an inner cabinet adjustment structure for a lifting cabinet, which includes a cabinet body, an inner cabinet installed inside the cabinet body by a lifting mechanism, the lifting mechanism and the inner cabinet being connected by an adjustment device, the adjustment device including a base fixed on the lifting mechanism and a fixed seat fixed on the side wall of the inner cabinet, the base and the fixed seat being connected as one unit by the adjustment seat.

[0005] The base has an open side that forms a sliding groove, and the adjustment seat is fitted into the sliding groove. The adjustment device also includes a drive knob, which is rotatably mounted on the adjustment seat and extends to the drive platform of the base. Rotating the drive knob causes the adjustment seat to slide up and down along the sliding groove.

[0006] The fixed seat covers the adjusting seat inside it. An inner transverse guide groove is provided through the fixed seat, a longitudinal guide groove is provided through the adjusting seat, and an outer hinge hole is provided through the base.

The second guide rod is connected to the outer transverse guide groove, the adjusting groove and the inner hinge hole in sequence and hinged together.

[0007] The up-and-down movement of the adjusting seat is coupled by the displacement of the first guide rod in the longitudinal guide groove and the displacement of the second guide rod in the adjusting groove. Rotating the drive knob forces the fixed seat to move laterally through the adjusting seat, thereby adjusting the lateral installation gap between the inner cabinet and the lifting mechanism.

[0008] The adjustment groove is a downwardly inclined, waist-shaped groove.

[0009] The longitudinal guide groove is a longitudinally extending waist-shaped groove; the inner transverse guide groove and the outer transverse guide groove are transverse waist-shaped grooves extending in the horizontal direction, and the transverse waist-shaped grooves are set perpendicular to the longitudinal waist-shaped grooves.

[0017] The beneficial effects of this utility model are: 1. Simple structure, low manufacturing cost, and improved market competitiveness.

[0018] By using an adjustment device to adjust the lateral installation gap during the assembly of the inner cabinet, the assembly difficulty is reduced, rework or maintenance caused by assembly errors is reduced, and costs are lowered.

[0019] The lateral installation gap is adjusted by using a multi-level, multi-directional linkage coupling method. The adjustment process is stable and smooth, and the adjustment operation is simple and quick.

[0020] The system provides comprehensive adjustment and control of the inner cabinets, ensuring they reach their optimal working condition, stable and reliable movement between the inner cabinets and the cabinet body, and extending their service life. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings. An inner cabinet adjustment structure for a lifting cabinet includes a cabinet body 1. An inner cabinet 10 is installed inside the cabinet body 1 via a lifting mechanism 11. The lifting mechanism 11 and the inner cabinet 10 are connected by an adjustment device 2. The adjustment device 2 includes a base 21 fixed to the lifting mechanism 11 and a fixing seat 22 fixed to the side wall of the inner cabinet 10. The base 21 and the fixing seat 22 are connected as one unit via an adjustment seat 23.

[0030] The base 21 has an open side that forms a sliding groove 211, and the adjusting seat 23 is embedded in the sliding groove 211. The adjusting device 2 also includes a drive knob 24, which is rotatably mounted on the adjusting seat 23 and extends to the drive platform 212 of the base 21. Rotating the drive knob 24 causes the adjusting seat 23 to slide up and down along the sliding groove 211.

[0031] The fixed base 22 covers the adjusting base 23 inside it. An inner transverse guide groove 31 is provided through the fixed base 22, a longitudinal guide groove 32 is provided through the adjusting base 23, and an outer hinge hole 33 is provided through the base 21. The first guide rod 3 is connected to the outer hinge hole 33, the longitudinal guide groove 32 and the inner transverse guide groove 31 in sequence and hinged. An inner hinge hole 41 is provided through the fixed base 22, an adjusting groove 42 is provided through the base 21, and an outer transverse guide groove 43 is provided through the base 21. The second guide rod 4 is connected to the outer transverse guide groove 43, the adjusting groove 42 and the inner hinge hole 41 in sequence and hinged.

[0032] The up-and-down movement of the adjusting seat 23 is coupled by the displacement of the first guide rod 3 in the longitudinal guide groove 32 and the displacement of the second guide rod 4 in the adjusting groove 42. The rotating drive knob 24 is rotated, and the adjusting seat 23 forces the fixed seat 22 to move laterally, thereby adjusting the lateral installation gap between the inner cabinet 10 and the lifting mechanism 11.

[0033] The adjustment groove 42 is a downwardly inclined oblique waist-shaped groove.

[0034] The longitudinal guide groove 32 is a longitudinally extending waist-shaped groove; the inner transverse guide groove 31 and the outer transverse guide groove 43 are transverse waist-shaped grooves extending in the horizontal direction, and the transverse waist-shaped grooves are set perpendicular to the longitudinal waist-shaped grooves.

[0035] The adjustment seat 23 has a rotating hole 231 on its top, and the drive knob 24 is installed in the rotating hole 231.

[0036] The drive knob 24 has a recessed back and a spirally distributed drive groove 241. Correspondingly, a number of drive platforms 212 are provided on the protruding end face inside the base 21. The drive groove 241 is connected to the drive platform 212. When the drive knob 24 is rotated, the drive groove 241 rotates along the drive platform 212, causing the adjustment groove 42 to slide up and down along the sliding groove 211.

[0037] The drive platform 212 has arc-shaped upper and lower end faces, and the upper and lower end faces of the drive platform 212 are connected by an arc.

[0038] The drive knob 24 is an eccentric wheel.

[0039] The inner cabinet 10 is connected to the fixed base 22 via the mounting base 6. A height adjustment groove 51 is provided through the fixed base 22, and the third guide rod 5 is slidably hinged to the height adjustment groove 51.

[0040] A height adjustment screw 7 is installed on the top of the mounting base 6, and an adjustment plate 61 is arranged horizontally inside the mounting base 6. The height adjustment screw 7 passes through the adjustment plate 61 and is screwed to the adjustment plate 61.

[0041] The bottom of the height adjustment screw 7 presses against the outer cylindrical surface of the third guide rod 5. Rotating the height adjustment screw 7 causes the mounting base 6 to move along the height adjustment groove 51 via the adjustment plate 61, thereby adjusting the longitudinal installation gap between the inner cabinet 10 and the lifting mechanism 11.

[0042] Working principle: Unlike the traditional direct installation of inner cabinets and lifting mechanisms, this case uses an adjustment device to connect the inner cabinets and lifting mechanisms. The adjustment device is used to adjust the installation gap during the assembly process of the inner cabinets, avoiding the situation where the assembly precision requirements are too high due to direct installation, reducing the assembly difficulty, reducing rework or maintenance caused by assembly errors, and reducing costs.

[0043] The specific adjustment device includes a base fixed to the lifting mechanism and a fixed seat fixed to the side wall of the inner cabinet. The base and the fixed seat are connected as one unit via an adjustment seat. The adjustment seat is embedded in a sliding groove formed by the opening of the base, while the fixed seat covers the adjustment seat inside. The adjustment device also includes a drive knob and a drive platform that docks with it on the base. The drive knob is rotatably mounted inside the adjustment seat, causing the adjustment seat to slide up and down along the sliding groove.

[0044] To convert the vertical movement of the adjusting seat into the horizontal movement of the fixed seat, thereby adjusting the horizontal installation gap between the inner cabinet and the lifting mechanism, specifically, an inner horizontal guide groove is provided through the fixed seat, a longitudinal guide groove is provided through the adjusting seat, and an outer hinge hole is provided through the base. The first guide rod is sequentially connected to the outer hinge hole, the longitudinal guide groove, and the inner horizontal guide groove for hinge connection. The fixed seat is provided with an inner hinge hole, the base is provided with an adjusting groove, and the base is provided with an outer horizontal guide groove. The second guide rod is sequentially connected to the outer horizontal guide groove, the adjusting groove, and the inner hinge hole for hinge connection. When the drive knob is rotated, the spiral drive groove on the back of the drive knob rotates along the drive platform, causing the adjustment seat to move up and down in the sliding groove. This drives the first guide rod to move in the longitudinal guide groove and the second guide rod to move synchronously in the adjustment groove. The displacement movements of the two are coupled together, converting the longitudinal displacement movement of the adjustment seat into the lateral displacement movement of the fixed seat. This achieves the adjustment of the lateral installation gap between the inner cabinet and the lifting mechanism. The linkage adjustment method, through multi-stage guidance and coupling, transmits and converts the direction of movement, resulting in high adjustment accuracy, a smooth and flexible adjustment process, and simple and quick operation.

[0045] Furthermore, the adjusting groove is a downwardly inclined oblique waist-shaped groove; the longitudinal guide groove is a longitudinally extending longitudinal waist-shaped groove; the inner transverse guide groove and the outer transverse guide groove are transverse waist-shaped grooves extending horizontally, and the transverse waist-shaped grooves are set perpendicular to the longitudinal waist-shaped grooves. The distribution of multi-level and multi-directional guide grooves and adjusting grooves can accurately convert linear motion into transverse adjustment, ensuring the reliability and stability of the adjustment process.

[0046] The inner cabinet and the fixed base are connected and fixed by a mounting bracket. A height adjustment groove is provided through the fixed base, and a third guide rod is slidably hinged to this height adjustment groove. Corresponding to the height adjustment groove, a height adjustment screw is provided on the top of the mounting base. The height adjustment screw is screwed to an adjustment plate provided inside the mounting base, and its bottom is pressed and locked against the outer cylindrical surface of the third guide rod. Rotating the height adjustment screw, through the screw connection to the adjustment plate, drives the mounting base to move up and down along the height adjustment groove, simultaneously driving the inner cabinet to adjust its height, thereby adjusting the longitudinal installation gap between the inner cabinet and the lifting mechanism.

[0047] Through the structural design of the adjustment device and height adjustment screw, users can adjust the lateral and longitudinal directions between the inner cabinet and the lifting mechanism in real time by rotating the drive knob and the height adjustment screw. This reduces the dependence on the machining accuracy of the inner cabinet and the lifting mechanism, effectively solving the precision requirements caused by direct connection, reducing assembly difficulty, and minimizing maintenance and replacement costs caused by assembly deviations. Multi-dimensional gap adjustment allows for multi-directional control of the inner cabinet's installation position, ensuring the inner cabinet reaches its ideal working state. Even after long-term operation, it maintains optimal assembly, improving the adaptability and stability of the inner cabinet and the cabinet body. Users can adjust the inner cabinet promptly according to specific usage needs, or make adjustments to local components or specific directions, extending the service life of the lifting cabinet. Therefore, it can be widely used.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
