Technical Field
[0001] This utility model belongs to the field of display rack technology, specifically relating to a telescopic shelf structure for display racks. Background Technology
[0002] In existing display rack technology, fixed shelf designs have significant drawbacks: the inability to adjust shelf positions severely limits space utilization. During off-peak hours or product restocking periods, fixed shelves occupy a large amount of unused space, wasting storage area and obstructing aisle passage and cleaning / maintenance. Furthermore, fixed structures cannot accommodate the display needs of products of different sizes; large items are difficult to place due to insufficient shelf spacing, while small items suffer from reduced display density and visual impact due to excessive shelf gaps. Traditional solutions, such as disassembling and reassembling shelves, are time-consuming and labor-intensive, and frequent operations can damage the rack structure. Therefore, there is an urgent need for a telescopic structure that can dynamically adjust shelf depth and optimize space configuration to improve the practicality and adaptability of display racks.
[0003] This invention attempts to solve or at least alleviate such problems by providing a shelf telescopic structure that can be quickly disassembled and assembled. Utility Model Content

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.
[0023] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.
[0024] In the embodiments, by Figure 1-5 Provided is a telescopic shelf structure for a display rack, comprising: a shelf 2, the shelf 2 being mounted on a mounting base 7, each mounting base 7 having an inner insert 71, and a sliding piece 5 having a second retaining ring 51, wherein the mounting base 7 is engaged by inserting the inner insert 71 into the second retaining ring 51, thereby achieving rapid assembly and stable transmission between the mounting base 7 and the sliding piece 5; a fixing piece 4 is provided on one side of the sliding piece 5, and the fixing piece 4 is engaged with a base 6 through a side engagement structure such as a first retaining ring 41, forming a sliding guide assembly; the base 6 is fixedly mounted on the uprights or crossbeams of the display rack, serving as the supporting foundation for the entire telescopic structure.
[0025] The fixed plate 4, sliding plate 5, base 6, and mounting base 7 are symmetrically arranged on the left and right sides of the shelf 2, forming a double-track sliding system. When the shelf 2 is pulled outward, the shelf 2 drives the mounting base 7 to move synchronously, and the mounting base 7 further drives the sliding plate 5 to slide along the guide path of the fixed plate 4, realizing the smooth extension and retraction of the shelf 2. The symmetrical double-track structure can balance the force on both sides of the shelf 2, avoid tilting or jamming caused by sliding on one side, and improve the smoothness and stability of the extension and retraction process; the snap-fit assembly, such as the snap-fit between the mounting base 7 and the sliding plate 5, and the fixed plate 4 and the base 6, simplifies the installation steps, eliminates the need for complicated tools, and reduces the assembly difficulty.
[0026] In a preferred embodiment of this utility model, a hanging rod 9 is fixedly installed at the bottom of the shelf 2. A pressure plate 91 is rotatably connected to the hanging rod 9 via a pivot. A spring 92 is installed between the top surface of the pressure plate 91 and the hanging rod 9, forming an elastic clamping assembly. A limiting groove 63 is provided at the end of the base 6 near the retracted end of the shelf 2. When the shelf 2 is retracted to the initial position, the pressure plate 91 automatically rotates downward under the elastic force of the spring 92, and its end engages in the limiting groove 63 of the base 6, thereby locking the shelf 2. The elastic force of the spring 92 drives the pressure plate 91 to automatically engage in the limiting groove 63, which can prevent the shelf 2 from accidentally slipping out due to external forces such as the shaking of the display rack, thus enhancing the stability of the retracted state. The rotatable pressure plate 91 is designed for easy manual unlocking by lifting the pressure plate upward, which is simple to operate and takes into account both safety and convenience.
[0027] In a preferred embodiment of this utility model, a connecting plate buckle 61 is provided on the inner side of the base 6 near the center of the display rack. The bases 6 on both sides are fixed to the connecting plate 8 by the connecting plate buckle 61, forming an integral base frame. The connecting plate 8 connects the two bases 6 into a unified structure, preventing the bases 6 from shifting due to the tension of the shelf 2 during expansion and contraction or the vibration of the display rack, thus improving the rigidity of the overall structure. The buckle-type connecting plate buckle 61 and the connecting plate 8 facilitate disassembly and maintenance, and adapt to the adjustment needs of different display rack sizes.
[0028] In a preferred embodiment of this utility model, the structure further includes a hanging plate 1, which has an insertion hole 11 and a rear insert 12. An outer insert 62 is provided on the outer side of the base 6 away from the center of the display rack. The outer insert 62 can be inserted into the insertion hole 11 of the hanging plate 1, while the rear insert 12 of the hanging plate 1 can be snapped onto the uprights or beams of the display rack. The hanging plate 1 is fixed to the display rack via the rear insert 12. After the outer insert 62 of the base 6 is inserted into the insertion hole 11 of the hanging plate 1, a stable connection chain of "display rack-hanging plate-base" is formed, preventing the base 6 from sliding or falling off relative to the display rack. The plug-in design of the outer insert 62 and the insertion hole 11 simplifies the assembly process of the base 6 and the display rack, improving installation efficiency.
[0029] As a preferred embodiment of this utility model, a groove 3 is provided at the front end of the shelf 2 near the outer side of the display rack. The shape of the groove 3 can be rectangular, arc-shaped, etc., and can be designed according to requirements. The groove 3 can be used to place display accessories such as price tags and product instruction labels, improving the clarity of information display; at the same time, the edge of the groove 3 can act as a barrier to prevent small exhibits on the shelf 2 from slipping due to tilting or vibration, thus enhancing display safety.
[0030] In a preferred embodiment of this invention, a side edge 72 is provided on the outer side of the mounting base 7 away from the center of the shelf 2, and the shelf 2 is disposed inside the side edge 72, that is, the side edge 72 wraps around the edge of the shelf 2. The side edge 72 limits the edge of the shelf 2, preventing the shelf 2 from swaying left and right due to uneven force during the extension and retraction process, thus improving sliding stability; at the same time, the side edge 72 can enhance the structural strength of the mounting base 7, preventing the mounting base 7 from deforming due to the large weight of the shelf 2.
[0031] In a preferred embodiment of this utility model, the surface of the shelf 2 is provided with multiple holes. The holes can be circular, elliptical, or strip-shaped, and their distribution can be uniform or designed according to load-bearing requirements. The holes can reduce the overall weight of the shelf 2 and reduce the load on the display rack; at the same time, the holes facilitate air circulation (such as displaying items that require ventilation) or be used to install additional accessories such as hooks and clips, expanding the functionality of the shelf 2 (such as hanging small exhibits).
[0032] Working principle: When the shelf 2 is pulled outward, the shelf 2 drives the mounting base 7 to move synchronously. The mounting base 7 engages with the second retaining ring 51 of the sliding piece 5 through the inner insert 71, restricting the sliding piece 5 from sliding along the guide path of the fixed piece 4. The fixed piece 4 is engaged and fixed with the base 6 through the first retaining ring 41, forming a double-track symmetrical sliding system. When the shelf 2 is retracted, the pressure plate 91 at the bottom of the shelf 2 is engaged in the limiting slot 63 of the base 6 by the elastic force of the spring 92 and locked in position. The connecting plate 8 is fixed to the two sides of the base 6 through the connecting plate buckle 61 of the base 6. The rear insert 12 of the hanging piece 1 is fixed to the display rack to achieve quick installation. Its insertion hole 11 is engaged with the outer insert 62 of the base 6 to reinforce the overall structure. The groove 3 at the front end of the shelf 2 is used to place labels. The surface holes reduce weight and enhance functionality. The side 72 of the mounting base 7 wraps around the edge of the shelf 2 to limit and prevent shaking.
[0033] In summary, the shelf telescopic structure of this utility model significantly improves the space utilization efficiency and functionality of the display rack. The double-track symmetrical sliding design combined with snap-fit assembly greatly enhances the stability and structural rigidity of shelf extension and retraction, effectively preventing tilting and jamming caused by unilateral force, while simplifying the installation process. The elastic limiting mechanism uses spring-driven pressure plates to automatically engage, ensuring the shelf is securely locked after retraction, preventing accidental slippage, and balancing ease of operation and safety. The connecting plate and hanging plate design enhances overall stability, suppresses vibration displacement, and supports quick assembly and disassembly to adapt to various scenarios. The shelf groove and hole structure expands functionality, facilitating label positioning, exhibit anti-slip, and accessory hanging, while reducing weight and load. This structure significantly optimizes the flexibility of merchandise display, meets the needs of exhibits of different sizes, and enhances the space adaptability and practical value of the display rack.
