Description

Technical Field

[0001] This utility model relates to the field of shelving technology, specifically a telescopic shelving. Background Technology

[0002] Telescopic shelves, as a type of furniture with adjustable storage space, are widely used in kitchens, bathrooms, balconies, and other places to accommodate the storage needs of items of different sizes. Existing telescopic shelves mostly use metal tracks combined with ball bearings or sliding rails to achieve their telescopic function, but they generally suffer from the following drawbacks: In humid environments (such as bathrooms and kitchens), metal parts are prone to rust due to moisture corrosion, leading to jamming or even failure during telescopic movement; traditional track structures often use a single-track design, with the left and right storage baskets directly contacting and rubbing against each other, which can easily cause wear and noise over time; secondly, during telescopic movement, there is a lack of effective limiting and stabilizing measures between the track and connecting parts, which can easily cause wobbling and misalignment, affecting stability and safety; furthermore, existing shelves are mostly assembled using bolts or welding, making disassembly and assembly inconvenient and difficult to maintain. Although some improvement solutions attempt to use coatings or seals to prevent rust, these often increase structural complexity and fail to fundamentally solve the problems of track friction and wobbling.

[0003] Therefore, a telescopic storage rack was designed to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0023] The following is a detailed description of a telescopic storage rack according to the present invention, with reference to the accompanying drawings.

[0024] Combined with appendix Figure 1-8 A telescopic storage rack includes a left storage basket 1, a right storage basket 2, and a waterproof telescopic mechanism. One end of the left storage basket 1 is located inside one end of the right storage basket 2. The waterproof telescopic mechanism is symmetrically arranged on both sides of the left storage basket 1 and the right storage basket 2. The left storage basket 1 and the right storage basket 2 can be smoothly pulled out and extended through the waterproof telescopic mechanism. The waterproof telescopic mechanism includes a waterproof telescopic connecting component 3, a left track plate 4, and a right track plate 5. The left track plate 4 is symmetrically arranged on both sides of the left storage basket 1, and the right track plate 5 is symmetrically arranged on both sides of the right storage basket 2. The waterproof telescopic connecting component 3 is fitted onto the left track plate 4 and the right track plate 5, and both the left track plate 4 and the right track plate 5 are slidably engaged with the waterproof telescopic connecting component 3 to realize the extension and retraction of the left storage basket 1 and the right storage basket 2 along the left track plate 4 and the right track plate 5. The lengths of the left track plate 4 and the right track plate 5 are adapted to the extension and retraction strokes of the left storage basket 1 and the right storage basket 2, providing guide tracks for the extension and retraction of the shelf, ensuring accurate extension and retraction direction, and avoiding deviation.

[0025] The waterproof telescopic connection assembly 3 includes a U-shaped sleeve 6 and a central partition 7. The central partition 7 is located in the middle of the U-shaped sleeve 6. Each side of the open end of the U-shaped sleeve 6 has a retainer 8. The U-shaped sleeve 6 fits onto the left track plate 4 and the right track plate 5. The central partition 7 is located in the middle of the left track plate 4 and the right track plate 5, forming a separation to prevent friction between the left track plate 4 and the right track plate 5. This effectively avoids direct contact and friction between the left track plate 4 and the right track plate 5 during telescopic sliding, reducing wear and ensuring smooth telescopic movement. The retainers 8 are protrusions extending inward from both sides of the open end of the U-shaped sleeve 6. The two retainers 8 are located below the left track plate 4 and the right track plate 5 respectively, cooperating with the inner wall of the U-shaped sleeve 6 to form a limiting space for the left and right track plates. This prevents the left track plate 4 and the right track plate 5 from sliding out of the U-shaped sleeve 6 during telescopic sliding, ensuring structural stability. The U-shaped housing 6, the central partition 7, and the card holder 8 are made of engineering plastics with excellent waterproof properties (such as ABS waterproof plastic) to ensure that they are not prone to rusting in humid environments.

[0026] The left storage basket 1 includes a first base frame 9, a first side frame 10, a first end frame 11, a first L-shaped fixing clip 12, and a first connecting clip 13. The first base frame 9, the first side frame 10, and the first end frame 11 are all formed by bending metal wire (such as stainless steel wire) and possess a certain load-bearing strength. The first base frame 9 has a rectangular frame structure and serves as the bottom support for the storage basket. Multiple first connecting clips 13 are provided on both sides and one end of the first base frame 9. First side frames 10 are provided on both sides of the first base frame 9. The first side frames 10 and the first base frame 9 are connected and fixed by the first connecting clips 13 located on both sides of the first base frame 9. Two first side frames 10 form side protection for the storage basket; the first base frame 9 has a first end frame 11 at one end where a first connecting clip 13 is provided, and the first end frame 11 and the first base frame 9 are connected and fixed by the first connecting clip 13 located at the end of the first base frame 9 to form end protection for the storage basket; the upper ends of the two first side frames 10 and the first end frame 11 are flush, and a first L-shaped fixing clip 12 is snapped into the upper corner of the first end frame 11, and the other end of the first L-shaped fixing clip 12 is snapped into the corresponding upper corner of the first side frame 10 to realize the connection and fixation between the first side frame 10 and the first end frame 11; The first L-shaped fixing clip 12 is made of elastic plastic. Both of its right-angled sides have slots on the inner side that are adapted to the wire. One right-angled slot of the first L-shaped fixing clip 12 is engaged with the corner wire of the first end frame 11, and the other right-angled slot is engaged with the corner wire of the corresponding first side frame 10. Through the elastic clamping force of the first L-shaped fixing clip 12, the connection between the first side frame 10 and the first end frame 11 is further strengthened, preventing loosening after long-term use. The left track plate 4 is mounted on the first side frame 10.

[0027] The upper end of the first end frame 11 is provided with a rotatable left handle 14. The left handle 14 can rotate around the pivot. When not in use, it can fit against the first end frame 11 without taking up space. When in use, it can be rotated to a horizontal position, making it convenient for the user to hold and pull out.

[0028] The first base frame 9 has symmetrically arranged downward protruding first limiting parts 15 on both sides of its lower end.

[0029] The right storage basket 2 includes a second base frame 16, a second side frame 17, a second end frame 18, a second L-shaped fixing clip 19, and a second connecting clip 20. The second base frame 16, second side frame 17, and second end frame 18 are all formed from the same stainless steel wire bent from the left storage basket 1. The second base frame 16 has a rectangular frame structure, its dimensions matching the first base frame 9, ensuring that one end of the left storage basket 1 can be inserted into it. Multiple second connecting clips 20 are provided on both sides and one end of the second base frame 16. Second side frames 17 are provided on both sides of the second base frame 16. The second side frames 17 and the second base frame 16 are connected by clips located on both sides of the second base frame 16. The second connecting clip 20 is connected and fixed to form the side protection of the storage basket; the second base frame 16 has a second end frame 18 at one end of the second connecting clip 20, and the second end frame 18 and the second base frame 16 are connected and fixed by the second connecting clip 20 located at the end of the second base frame 16 to form the end protection of the storage basket; the upper ends of the two second side frames 17 and the second end frame 18 are flush, and the upper corner of the second end frame 18 is clamped with a second L-shaped fixing clip 19, and the other end of the second L-shaped fixing clip 19 is clamped with the corresponding upper corner of the second side frame 17 to realize the connection and fixation between the second side frame 17 and the second end frame 18; The second L-shaped fixing clip 19 is made of elastic plastic. Both of its right-angled sides have slots on the inner side that are adapted to the wire. One right-angled slot of the second L-shaped fixing clip 19 is engaged with the corner wire of the second end frame 18, and the other right-angled slot is engaged with the corner wire of the corresponding second side frame 17. Through the elastic clamping force of the second L-shaped fixing clip 19, the connection between the second side frame 17 and the second end frame 18 is further strengthened, preventing loosening after long-term use. The right track plate 5 is mounted on the second side frame 17.

[0030] The upper end of the second end frame 18 is provided with a rotatable right handle 21. The right handle 21 can rotate around the pivot. When not in use, it can fit against the second end frame 18 without taking up space. When in use, it can be rotated to a horizontal position for easy gripping and pulling operation.

[0031] The second base frame 16 has symmetrically arranged downward protruding second limiting parts 22 on both sides of its lower end.

[0032] In specific implementation, this utility model During assembly, the left storage basket 1 and the right storage basket 2 are first assembled using the first connecting clip 13 and the second connecting clip 20, respectively, and the corners are reinforced with L-shaped fixing clips. Then, one end of the left storage basket 1 is placed inside one end of the right storage basket 2. At this time, the left storage basket 1 and the right storage basket 2 will partially overlap and cross each other, and the left track plate 4 and the right track plate 5 will overlap. Finally, the U-shaped sleeve 6 of the waterproof telescopic connecting component 3 is put on the overlapping track plate 4 and the right track plate 5, so that the middle partition 7 is located between the two track plates, and the clip 8 supports the bottom of the track plate. Telescopic Operation: When the length of the shelf needs to be increased, the user can hold the second side frame 17 of the right shelf 2 with one hand and grasp the left handle 14 with the other hand, pulling the left shelf 1 away from the right shelf 2; or hold the first side frame 10 of the left shelf 1 with one hand and grasp the right handle 21 with the other hand, pulling the right shelf 2 away from the left shelf 1. At this time, the left track plates 4 on both sides of the left shelf 1 and the right track plates 5 on both sides of the right shelf 2 will slide horizontally relative to each other within the U-shaped sleeve 6 of the waterproof telescopic connecting assembly 3, thereby increasing the overall length of the shelf. When the length of the shelf needs to be decreased, simply push the left shelf 1 or the right shelf 2 in the opposite direction. The left track plates 4 and the right track plates 5 will slide in opposite directions within the U-shaped sleeve 6, and one end of the left shelf 1 will be further embedded into the interior of the right shelf 2. Stability and Waterproofing: During the telescopic process, the central partition 7 of the waterproof telescopic connecting component 3 constantly separates the left track plate 4 and the right track plate 5, preventing direct friction and reducing wear. The clip 8 provides a lower limit for the left and right track plates, preventing them from sliding out of the U-shaped sleeve 6, ensuring stable telescopic movement without deviation. Meanwhile, the U-shaped sleeve 6 is made of waterproof engineering plastic, effectively preventing rust even in humid environments such as kitchens and bathrooms. It also blocks moisture from directly contacting the sliding contact surfaces of the left and right track plates, slowing down the corrosion rate and ensuring smooth telescopic function even after long-term use. Stability in use: When the shelf is placed, the first limiting part 15 and the second limiting part 22 work together to increase the friction with the placement surface and prevent the shelf from shifting due to the placement of items or slight collisions; the modular assembly structure of the left and right storage baskets (connecting clips and L-shaped fixing clips cooperate) ensures that each part is firmly connected and can stably support items, avoiding items from falling due to loose connections.
