Description

Technical Field

[0001] This invention relates to the field of cabinet technology, and in particular to a vertically lifting hanging cabinet basket. Background Technology

[0002] Currently, wall cabinets in family kitchens are usually installed high up to store infrequently used items. However, due to the height limitations of wall cabinets, users often need to use a stool or stand on tiptoe to retrieve items, which is not only inconvenient but also poses certain safety hazards.

[0003] To address this issue, existing technologies offer numerous designs for lift-up baskets, most of which utilize sliding rail structures or coil spring mechanisms to achieve vertical lifting. Among them, Chinese utility model patent CN211748069U discloses a lift-up sliding rail basket, which uses a three-section ball bearing sliding rail to achieve its lifting function. However, this design has a significant drawback: during the lifting process, the user needs to operate a lever to separate the brake block from the sliding rail. This action generates a horizontal force on the basket, causing the force direction to be inconsistent with the movement direction when the sliding rail moves vertically. This makes the sliding rail prone to jamming during lifting, potentially causing the trays inside the basket to collide and be damaged.

[0004] Therefore, there is an urgent need for a vertical lifting cabinet basket that can lift smoothly and is less prone to jamming. Summary of the Invention

[0005] The purpose of this invention is to provide a vertical lifting cabinet basket to solve the problems mentioned in the background art.

[0006] The above-mentioned objective of this invention is achieved through the following technical solution: a vertical lifting hanging cabinet basket, comprising a cabinet body, a pull-out basket, and a slide rail assembly, wherein the pull-out basket is connected to the cabinet body via the slide rail assembly and moves in and out of the cabinet body vertically, and the slide rail assembly comprises: Fixed slide rails are installed on the inner walls of both sides of the cabinet, and a first guide groove is provided on them that runs vertically through the cabinet. Movable slide rails are provided on the side walls on both sides of the pull basket, and the movable slide rails extend into the first guide groove; Rollers are disposed on the side walls on both sides of the pull basket and are tactilely disposed within the first guide groove; The guide wheel is located at the lower end of the fixed slide rail and is clamped to both sides of the movable slide rail from front to back.

[0007] Preferably, the roller has a groove on its surface, and a guide bar is provided on the inner wall of the first guide groove. The guide bar cooperates with the groove to guide the rolling of the roller.

[0008] Preferably, the guide strips are provided as two strips, distributed on both sides of the axle of the roller.

[0009] Preferably, the guide wheel is fixedly disposed in the first guide groove and located below the roller to prevent it from dislodging from the first guide groove.

[0010] Preferably, the movable slide rail is provided with second guide grooves on its front and rear sides, and the guide wheel is rotatably disposed in the second guide groove.

[0011] Preferably, the movable slide rail has a T-shaped cross-section, and the T-shaped movable slide rail forms two second guide grooves at the front and rear between itself and the side wall of the pull basket. The lower end of the fixed slide rail is provided with a T-shaped inlet and outlet that matches the cross-sectional shape of the movable slide rail.

[0012] Preferably, the diameter of the guide wheel is smaller than the radius of the roller.

[0013] Preferably, when the roller is at its lowest point, the angle between the line connecting the center of the roller and the center of the guide wheel and the vertical direction is less than 30°.

[0014] Preferably, L-shaped brake components, connecting rods, and swing rods are provided on the side walls of both sides of the pull-out basket. The L-shaped brake component is installed at the upper end of the pull-out basket via a pivot, with one end for contacting the side of the fixed slide rail and the other end connected to the upper end of the connecting rod. The middle part of the swing rod is installed at the lower end of the pull-out basket via a pivot, with its upper end connected to the lower end of the connecting rod. An operating lever is provided below the pull-out basket, with both ends of the operating lever connected to the swing rods on both sides respectively.

[0015] Preferably, one end of the L-shaped brake component is provided with a brake block for contacting the side of the fixed slide rail, and the other end is connected to the side wall of the basket with a spring.

[0016] The beneficial effects of this invention are: 1. This invention achieves vertical lifting and lowering of the pull-out basket through a combination design of fixed slide rail, movable slide rail, rollers, and guide wheels. The rollers roll within the first guide groove, and the guide wheels clamp both sides of the movable slide rail, effectively preventing the pull-out basket from jamming during lifting and lowering, and avoiding collisions caused by the bowls and plates inside the basket due to movement jamming; 2. The structure of rollers and guide wheels reduces sliding friction and lowers operating resistance, allowing users to easily pull the basket out or push it back into the cabinet, improving ease of use.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0020] Example: like Figure 1-5 As shown, a vertical lifting hanging cabinet basket includes a cabinet body 1, a pull-out basket 2 and a slide rail assembly 3. The pull-out basket 2 is connected to the cabinet body 1 through the slide rail assembly 3 and can move in and out of the cabinet body 1 vertically.

[0021] The upper end of the cabinet 1 is provided with a spring seat 5, which is connected to the pull-out basket 2 through a spring 4. Specifically, the spring seat 5 is equipped with a roller, and the spring 4 is wound on the roller. One end of the spring 4 is fixedly connected to the pull-out basket 2.

[0022] The number of coil springs 4 can be set to two, three or more.

[0023] The slide rail assembly 3 includes: a fixed slide rail 301, a movable slide rail 302, a roller 304 and a guide wheel 305, wherein the fixed slide rail 301 is fixedly installed on the inner walls on both sides of the cabinet 1, and the fixed slide rail 301 is provided with a first guide groove 303 that runs vertically through the cabinet.

[0024] The movable slide rail 302 is fixedly installed on the side walls on both sides of the pull basket 2, and the movable slide rail 302 extends into the first guide groove 303.

[0025] Rollers 304 are mounted on the side walls of the pull-out basket 2 via pivots and are rotatably positioned within the first guide groove 303. To prevent rollers 304 from moving axially, as follows: Figure 4 and Figure 5 As shown, the roller 304 has a groove 307 on its surface, and a guide bar 306 is provided on the inner wall of the first guide groove 303. The guide bar 306 is embedded in the first guide groove 303. There are two guide bars 306, which are distributed on both sides of the axle of the roller 304.

[0026] The guide bar 306 cooperates with the wheel groove 307 to guide the rolling of the roller 304 and prevent the roller 304 and the pull basket 2 from moving in the front-back and left-right directions.

[0027] like Figure 4 As shown, the guide wheel 305 is mounted on the lower end of the fixed slide rail 301 via a pivot, clamping it between the two sides of the movable slide rail 302. Specifically, the guide wheel 305 is fixed within the first guide groove 303 via the pivot, allowing it to rotate only within the first guide groove 303 relative to its pivot. Furthermore, the guide wheel 305 is located below the roller 304 to prevent it from disengaging from the first guide groove 303.

[0028] The diameter of the guide wheel 305 is smaller than that of the roller 304. This ensures that the guide wheel 305 is positioned within the first guide groove 303, while minimizing the angle α between the line connecting the centers of the guide wheel 305 and the roller 304 and the vertical direction (i.e., the direction of movement). Figure 4 As shown, when the pull-out basket 2 descends to its lowest height, the roller 304 is at its lowest point. The angle α between the line connecting the center of the roller 304 and the center of the guide wheel 305 and the vertical direction is less than 30°. This ensures that when the pull-out basket 2 needs to be lifted upwards, the slide rail assembly 3 will not jam or get stuck even when the pull-out basket 2 is subjected to a horizontal force, making the pull-out basket 2 smoother and preventing the bowls and plates inside the pull-out basket 2 from colliding due to jamming.

[0029] With the cooperation of roller 304 and guide bar 306, and guide wheel 305 and movable slide rail 302, movable slide rail 302 is stably restricted to fixed slide rail 301, and can only move up and down and not in the front, back, left and right directions. The relative movement between movable slide rail 302 and fixed slide rail 301 changes from the existing sliding friction to rolling friction, which reduces the resistance to lifting and making the movement of basket 2 more effortless and smooth.

[0030] Among them, such as Figure 3 As shown, the movable slide rail 302 is provided with second guide grooves 308 on the front and rear sides respectively, and the guide wheel 305 is rolled in the second guide groove 308. The movement of the movable slide rail 302 is further restricted by the cooperation between the second guide groove 308 and the guide wheel 305.

[0031] In this embodiment, the movable slide rail 302 has a T-shaped cross-section. The T-shaped movable slide rail 302 forms two front and rear second guide grooves 308 between itself and the side wall of the pull basket 2. The lower end of the fixed slide rail 301 is provided with a T-shaped inlet and outlet 309 that matches the cross-sectional shape of the movable slide rail 302.

[0032] like Figure 3 As shown, L-shaped brake components 6, connecting rods 7, and swing rods 8 are provided on the side walls of both sides of the pull-out basket 2. The L-shaped brake component 6 is installed at the upper end of the pull-out basket 2 via a pivot, with one end contacting the side of the fixed slide rail 301 and the other end connected to the upper end of the connecting rod 7. The middle part of the swing rod 8 is installed at the lower end of the pull-out basket 2 via a pivot, and its upper end is connected to the lower end of the connecting rod 7.

[0033] One end of the L-shaped brake component 6 is provided with a brake block 10 for contacting the side of the fixed slide rail 301, and the other end is connected to the side wall of the pull basket 2 with a spring 11.

[0034] An operating lever 9 is provided below the pull basket 2, and the two ends of the operating lever 9 are connected to the swing levers 8 on both sides respectively.

[0035] like Figure 3 As shown, in its natural state, the L-shaped brake 6 rotates clockwise under the force of the spring 11, causing the brake block 10 to contact the side of the fixed slide rail 301, thus preventing the pull-out basket 2 from moving downwards. When it is necessary to raise or lower the pull-out basket 2, the operating lever 9 is pulled downwards. At this time, the swing lever 8 rotates clockwise, and its upper end swings upwards. Through the connecting rod 7, the L-shaped brake 6 swings counterclockwise, causing the brake block 10 to separate from the side of the fixed slide rail 301. At this time, the pull-out basket 2 can move freely up and down. After releasing the operating lever 9, the L-shaped brake 6 returns to its original position under the force of the spring 11, causing the brake block 10 to contact the side of the fixed slide rail 301, thus fixing the position of the pull-out basket 2.
