Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing technology, and in particular to a bookcase with adjustable storage space. Background Technology

[0002] As an indispensable piece of furniture in daily life, the design of a bookcase directly impacts the user experience and space utilization. Traditional bookcases use a fixed shelf structure, which has several drawbacks: the non-adjustable shelf height makes it unsuitable for storing items of different heights; accessing items in the upper shelves is inconvenient and poses safety hazards; and it lacks intelligent functional modules, such as integrated lighting systems. Although some bookcases with adjustable shelf heights have appeared on the market, the adjustment process is cumbersome and fails to fundamentally solve the problem of flexible space adaptability. Existing bookcases with height-adjustable functions mostly use electric drives, which are not only structurally complex and costly but also functionally limited, failing to organically combine adjustable storage space, convenient access, and auxiliary lighting. These problems severely restrict the practicality and user experience of bookcase products. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to provide a bookcase with adjustable shelf height, convenient access, and integrated lighting that can change storage space.

A placement cavity is formed inside the rear inner surface of the bookcase body, and the placement cavity is connected to the guide rail groove. A cavity is formed at the lower end of the rear inner surface of the bookcase body, and the cavity is connected to the placement cavity. A worm wheel is provided in the cavity, and a worm gear for driving the worm wheel is meshed with the worm wheel. The left end of the worm gear extends through the bookcase body to the outside of the bookcase body. A rotating block is provided at the left end of the worm gear, and the rotating block is located on the left side of the bookcase body. A screw is connected to the worm wheel, and the screw is located in the placement cavity. A lifting plate is spirally sleeved on the screw. The left and right ends of the lifting plate are connected to the lifting placement frame via connecting plates. The connecting plates pass through the guide rail groove and are connected to the lifting placement frame.

[0006] Furthermore, the pull-out component includes a guide wheel, and limit grooves are provided at both the upper and lower ends of the pull-out groove. L-shaped blocks are provided at the left ends of the upper and lower surfaces of the support plate. The guide wheel is embedded in the limit groove on the L-shaped block, and a rubber anti-collision block is provided on the right side of the vertical plate of the L-shaped block.

[0007] The beneficial effects of this utility model are as follows: This utility model achieves the adjustment of the floor height by driving the lifting and placing frame through the lifting component, expands the storage space with the pull-out support plate, and improves the convenience of use by combining the embedded lighting strip.

[0010] Figure 3 This is a schematic diagram of the internal structure of this utility model. Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] Please see Figures 1 to 3As shown, this utility model provides an embodiment: a bookcase with adjustable storage space, including a bookcase body 1, a placement plate 11 is provided at the lower end of the bookcase body 1, guide rail grooves 12 are provided at both the left and right ends of the upper side of the inner rear surface of the bookcase body 1, a lifting placement frame 2 is provided at the upper end of the bookcase body 1, and a lifting component 3 for driving the lifting placement frame 2 to move up and down is provided on the inner rear surface of the bookcase body 1, a pull-out groove 21 is provided on the right side of the upper and lower horizontal plates of the lifting placement frame 2, a support plate 22 is provided in the pull-out groove 21 through the pull-out component 4, the right ends of the support plates 22 at the upper and lower ends are connected by a connecting rod 23, and multiple lighting strips 24 are embedded at equal intervals on the lower surface of the upper support plate 22.

[0013] In this utility model, the right side of the bookcase body 1 has an opening 10 to facilitate the pull-out action of the support plate 22.

[0014] The lifting drive device refers to the mechanism that achieves vertical movement of the frame through mechanical transmission. Specifically, it can be implemented using a worm gear and worm wheel transmission system. The rotation of the worm gear drives the worm wheel to rotate the screw, thereby pushing the lifting plate along the guide rail groove. The pull-out mechanism is a guiding structure that allows the support plate to extend and retract horizontally. Specifically, it can be implemented using a sliding assembly with a guide wheel and a limiting groove. The guide wheel slides within the limiting groove, and the support plate is connected to the guide wheel via an L-shaped block. The lighting strip is a linear light source embedded in the lower surface of the support plate. Specifically, it can be implemented using LED light strips, powered and controlled by a built-in circuit.

[0015] Specifically, when the worm gear of the lifting drive rotates, the worm wheel drives the screw to rotate, causing the lifting plate sleeved on the screw to move up and down along the guide rail groove, thereby adjusting the height of the lifting and placing frame. When it is necessary to expand the operating space, the support plate is pulled horizontally out of the pull-out slot via a pull-out mechanism, and the connecting rod keeps the upper and lower support plates moving synchronously. The lighting strip automatically or manually turns on after the support plate is pulled out, providing illumination to the space below. Adjusting the shelf height by lifting the frame can accommodate different item sizes; pulling out the support plate expands the operating area and avoids climbing; and the built-in lighting directly illuminates the book area.

[0016] Compared to existing technologies, traditional bookcases rely on fixed shelves and external lighting, while this solution achieves flexible space adjustment through a mechanical lifting and pull-out structure, while also integrating lighting functionality. Compared to electric lifting bookcases, the worm gear transmission structure simplifies the drive system and reduces manufacturing costs; the pull-out support plate and connecting rod design maintains structural stability while expanding space, avoiding the cumbersome operation of traditional manual shelf adjustment.

[0017] Through the above technical solutions, this application realizes the dynamic adjustment of the bookcase storage space to adapt to the storage needs of items of different sizes; the pull-out support plate expands the operating area and improves the convenience and safety of accessing the upper space; the built-in lighting strip directly illuminates the book display area and improves the search efficiency in low-light environments.

[0018] Please continue reading. Figures 1 to 3 As shown, in one embodiment of this utility model, the lifting component 3 includes a worm gear 31. A placement cavity 32 is formed in the rear inner surface of the bookcase body 1, and the placement cavity 32 is connected to the guide rail groove 12. A cavity 33 is formed at the lower end of the rear inner surface of the bookcase body 1, and the cavity 33 is connected to the placement cavity 32. A worm wheel 34 is provided in the cavity 33, and a worm gear 31 for driving the worm wheel 34 is meshed with the worm gear 34. The left end of the worm gear 31 passes through the... The bookcase body 1 extends outside the bookcase body 1. A rotating block 36 is provided at the left end of the worm gear 35 and the rotating block 36 is located on the left side of the bookcase body 1. A screw 37 is connected to the worm wheel 34 and is located inside the placement cavity 32. A lifting plate 38 is spirally sleeved on the screw 37. The left and right ends of the lifting plate 38 are connected to the lifting placement frame 2 via connecting plates. The connecting plates pass through the guide rail groove 12 and are connected to the lifting placement frame 2.

[0019] The components are as follows: A worm gear is a transmission rod with helical teeth, specifically made by machining helical grooves into a metal rod, used to transmit rotational motion to a worm wheel. A worm wheel is a gear that meshes with the worm gear, specifically made by casting copper alloy, used to convert the worm gear's rotational motion into the vertical lifting motion of the screw. A screw is a cylindrical rod with external threads, specifically manufactured by cold rolling or machining processes, used to drive the lifting plate to move through threaded engagement. A lifting plate is a flat plate structure fitted onto the screw, specifically made by stamping steel plate, used to support the connecting plate and transmit lifting force. A connecting plate is a transition component connecting the lifting plate and the lifting placement frame, specifically made by cutting aluminum alloy profiles, used to convert the linear motion of the lifting plate into the overall displacement of the lifting placement frame.

[0020] Specifically, when the rotating block is manually rotated, the worm gear drives the worm wheel to rotate, which in turn drives the screw to rotate around its axis. Since the lifting plate is threaded onto the screw, the screw's rotational motion is converted into the vertical movement of the lifting plate. The lifting plate is fixedly connected to the lifting and placing frame via connecting plates on both sides, allowing the lifting and placing frame to move vertically along the guide rail groove. The guide rail groove constrains the movement trajectory of the connecting plate, ensuring stability during the lifting process. Through the self-locking characteristic of the worm gear transmission mechanism, the lifting and placing frame can remain stationary at any height.

[0021] Compared to existing technologies, traditional bookcases using electric lifting mechanisms rely on motors and circuit control, resulting in complex structures and high maintenance costs. This solution, however, utilizes a worm gear and screw mechanical transmission structure to achieve purely manual lifting, avoiding reliance on electricity. Compared to existing bookcases with manually adjustable shelf heights, this solution achieves continuous adjustment of storage space through the overall frame lifting mechanism. Furthermore, the worm gear transmission offers higher transmission stability than ordinary gears, effectively preventing slippage or jamming during lifting.

[0022] Through the above technical solution, this application solves the problem of low space utilization caused by the fixed shelf height of traditional bookcases. The lifting and lowering of the frame can be smoothly achieved by manually rotating the worm gear, allowing the bookcase to flexibly adapt to the storage needs of items of different heights. No external tools or electrical equipment are required during the lifting process, making operation simple and highly reliable. At the same time, the self-locking characteristic of the worm gear drive prevents the frame from sliding down due to gravity, ensuring safety during use.

[0023] Please continue reading. Figures 1 to 3 As shown, in one embodiment of the present invention, the pull-out component 4 includes a guide wheel 41, and limit grooves 42 are provided at both the upper and lower ends of the pull-out groove 21. L-shaped blocks 43 are provided at the left ends of both the upper and lower surfaces of the support plate 22. The guide wheel 41 is embedded in the limit groove 42 on the L-shaped block 43, and a rubber anti-collision block 44 is provided on the right side of the vertical plate of the L-shaped block 43.

[0024] Among them, the guide wheel refers to the rolling component installed on the edge of the support plate. Specifically, it can be implemented by a metal wheel body with bearings, which reduces the frictional resistance when the support plate moves through rolling contact.

[0025] The limiting groove refers to the groove structure opened on the upper and lower walls of the pull-out groove. Specifically, it can be implemented using a straight channel to limit the movement trajectory of the guide wheel and prevent the support plate from detaching.

[0026] The L-shaped block refers to a connector with a vertical bending structure, which can be made by stamping steel plate. It is used to fix the guide wheel to the edge of the support plate and transmit the load.

[0027] Among them, the rubber anti-collision block refers to an elastic buffer component, which can be made by molding vulcanized rubber. It absorbs kinetic energy through contact and collision to avoid rigid impact between the support plate and the inner wall of the pull-out groove.

[0028] Specifically, as the support plate moves horizontally along the pull-out groove, the guide wheel rolls within the limiting groove to provide linear guidance. The L-shaped block transfers the load of the support plate to the guide wheel, and the rubber anti-collision block contacts the inner wall of the pull-out groove for cushioning when the support plate reaches its limit position. Through the cooperation of the guide wheel and the limiting groove, the support plate maintains a stable movement trajectory during the pull-out process, while the rubber anti-collision block eliminates the risk of collision damage caused by inertia.

[0029] Compared to existing technologies, traditional bookcase pull-out structures typically use direct sliding contact between the slide rail and the slider, resulting in high frictional resistance and easy wear. This solution replaces the sliding contact with a rolling guide, significantly reducing movement resistance and extending service life. Furthermore, the added rubber anti-collision blocks, not found in existing technologies, effectively prevent structural deformation or noise problems caused by frequent collisions.

[0030] Through the above technical solution, this application achieves smoothness and stability of the pull-out operation of the support plate, solves the problems of easy jamming and rapid wear of traditional bookcase pull-out structures, and extends the service life of the support plate and pull-out groove through buffer collision protection.

[0031] The lighting strip in this invention is existing technology, which is already well understood by those skilled in the art, and will not be described in detail here.

[0032] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
