Description

Technical Field

[0001] This utility model relates to the field of storage furniture technology, and in particular to a retractable shelf. Background Technology

[0002] Shelves are a common type of storage furniture used to store books, decorations, and miscellaneous items. They are simple in design, highly practical, and widely used in homes, offices, shops, and other places. They can meet different storage needs and decorating styles, and proper selection and use can improve space utilization.

[0003] Existing shelves are usually composed of a support frame and shelves connected together. The support frame serves as the main structure supporting the shelves, and several shelves can be installed at the vertical height of the support frame. After assembly, the shelves serve as a flat surface for placing items directly. For example, Chinese utility model patent CN209629024U, entitled "A Structurally Stable Folding Frame," describes a series of support plates and supports on both sides of the support plates. The support plates are divided into a top plate and multiple folding plates located below the top plate. The top plate is an integral structure, with its left end rotatably connected to the support on the same side and its right end overlapping the support on the same side. The folding plates are divided into left and right layers. The sides of the left and right layers that are far apart from each other are rotatably connected to the support on the same side. The sides of the left and right layers that are close to each other are provided with a first and a second connector that cooperate with each other. The first and second connectors are rotatably connected by a rotating pin. When the folding frame is unfolded, the locking plate is engaged with the snap fastener to keep the folding frame stable. When the folding frame is folded up, the locking plate is disengaged from the snap fastener, causing the top support plate to rotate to the left and be placed to one side.

[0004] However, the existing technology still has the following drawbacks:

[0005] 1. Existing shelves used for placing items are either fixed or foldable. Fixed shelves cannot be folded or extended, and take up a lot of space. Foldable shelves can be folded for storage, but the size of the storage space cannot be adjusted according to the user's needs, making them inflexible. Both of these structural designs are limited by the application space scenario.

[0006] 2. Existing shelving support frames are usually designed with a fixed structure, which cannot be freely disassembled and reassembled according to the number of shelves. Even after being folded and stored, the support frame still occupies a lot of space and has high transportation costs. Moreover, the fixed structure design of the support frame is relatively difficult to disassemble and assemble, and the maintenance and replacement costs are relatively high.

[0007] 3. The shelves used in existing shelving are usually quite heavy, difficult to install, and have high material costs. Some vendors have made holes in the shelves, but they are still quite heavy. Some vendors use wire mesh shelves, but their structural design is not stable enough, resulting in low load-bearing capacity of the shelving. Utility Model Content

[0040] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0041] like Figure 1-9 As shown, a retractable shelf is used to store books, decorations, sundries, and other items. It is widely used in homes, offices, shops, and other places, and can meet different storage needs and decoration styles. Reasonable selection and use can improve space utilization. The retractable shelf includes a side frame assembly 10 and a shelf layer assembly. The side frame assembly 10 has a first side tube frame 101 and a second side tube frame 102. The first side tube frame 101 and the second side tube frame 102 are each composed of at least two parallel vertical tubes. The vertical tubes are fixed together by a horizontal connector. In this embodiment, the vertical tubes are kept in a fixed connection relationship by the shelf layer assembly.

[0042] The storage layer assembly includes an inner storage layer 20 and an outer storage layer 30. The inner storage layer 20 has an inner fixed end 201 and an inner movable end 202 at its two ends. The inner fixed end 201 is detachably connected to the vertical tube of the first side tube frame 101 through a sleeve 205. The inner movable end 202 serves as one end that can be telescopically connected to the outer storage layer 30. If necessary, a sliding mechanism (such as a roller or slider) can be provided on the inner movable end 202.

[0043] In addition, the outer storage layer 30 has an external fixed end 301 and an external movable end 302 at its two ends. The external fixed end 301 is also detachably connected to the vertical tube of the second side tube rack 102 through a sleeve 205. The external movable end 302 is provided with a limiting component 40 (such as a limiting rod, a limiting ring, or a buckle). The front and rear edges of the outer storage layer 30 are provided with guide grooves 305 (such as an L-shaped plate 3051, a U-shaped track, or a slide).

[0044] In the telescopic operation of the storage layer assembly, the inner movable end 202 of the inner storage layer 20 is embedded in the guide groove 305 of the outer storage layer 30. The telescopic adjustment of the storage layer assembly is achieved by manually pushing and pulling the inner storage layer 20 to slide laterally along the guide groove 305. After sliding to the target position, the sliding stroke of the limiting component 40 is locked by tightening or other operations.

[0045] Therefore, by sliding the inner storage layer 20 and the outer storage layer 30 together, the horizontal expansion and contraction of the storage space can be adjusted to flexibly adapt to the needs of different application scenarios, solving the problem of insufficient flexibility of previous fixed structures or folding shelves; the design of the guide groove 305 and the limiting component 40 ensures the stability of the sliding process, avoids the shaking of the storage layer, and improves the load-bearing capacity; the retractable structure design of the storage layer component allows for folding and storage when not in use, significantly reducing the space occupied and lowering transportation and storage costs.

[0046] The limiting component 40 of this application embodiment has a limiting screw 401, which is used to lock the inner layer 20. Specifically, the limiting screw 401 is installed in pre-drilled holes on the upper and / or bottom of the front and rear sides of the outer movable end 302 of the outer layer 30. In this application embodiment, the limiting screw 401 is preferably installed at the bottom of the front and rear sides of the outer movable end 302.

[0047] When the built-in layer 20 slides to the target position, tighten the limiting screw 401 so that the end of the screw passes through the guide groove 305 and abuts against the side of the built-in layer 20, thereby fixing the built-in layer 20; when adjustment is needed, loosen the screw to release the lock and adjust the sliding position of the built-in layer 20 on the guide groove 305, that is, adjust the storage space of the built-in layer 20 and the outer layer 30.

[0048] Therefore, the limit screw 401 with a simple structure is set by the limit component 40, which is easy to operate and allows users to quickly adjust the locking state with manual tools; moreover, the multi-point (top and bottom) limit design enhances the locking stability and prevents the shelf from sliding unexpectedly under load.

[0049] A protruding limiting portion 2021 (or a concave limiting groove formed by stamping) is welded to the outer side of the inner movable end 202. For example, the limiting portion 2021 is formed by welding a ring-shaped metal rod. The limiting assembly 40 of this application embodiment also includes a limiting plate 402, which has an assembly portion 4021 and a blocking portion 4022. The assembly portion 4021 and the blocking portion 4022 are integrally formed. The assembly portion 4021 is fixed to the outer movable end 302 by the aforementioned limiting screw 401, and the blocking portion 4022 is bent and extends above the guide groove 305.

[0050] When the inner layer 20 slides, the limiting part 2021 of the inner movable end 202 can be limited by selecting the limiting screw 401 or the limiting plate 402 to physically control the movement range of the inner layer 20 on the guide groove 305; and the sliding stroke can be customized by adjusting the installation angle or position of the limiting plate 402.

[0051] Therefore, the limiting plate 402 and the limiting screw 401 provided by the limiting component 40 provide double locking protection for the built-in layer 20, preventing accidental unlocking caused by loose screws, improving the safety of adjusting the storage space between the built-in layer 20 and the outer storage layer 30, and optimizing space utilization by bending the blocking part 4022 of the limiting plate 402, avoiding interference with other structures such as the storage layer.

[0052] The structural design of the built-in shelf 20 and the outer shelf 30 in this embodiment is further described below: The built-in shelf 20 has vertically extending inner side mesh frames 203 (mesh-like metal frames) welded to its front and rear sides, and the outer shelf 30 has vertically extending outer side mesh frames 303 welded to its front and rear sides. Furthermore, the inner fixed end 201 has an inner end mesh frame 204, and the outer fixed end 301 has an outer end mesh frame 304. Both the inner and outer end mesh frames 204 are also mesh-like metal frames. Therefore, the mesh frame structure design of the shelf reduces its weight and material costs while maintaining sufficient structural strength. The vertically extending side and end mesh frames enhance the bending resistance of the shelf edges and improve load-bearing capacity.

[0053] Sleeves 205 (such as cylindrical or square steel pipes) are welded to the corners of the inner side frame 204 and the outer side frame 304. These sleeves 205 also connect the inner side frame 203 and the outer side frame 303. The vertical pipes of the first side frame 101 and the second side frame 102 are inserted into the corresponding sleeves 205 and fixed with pins or bolts. Therefore, the sleeve 205 connection method enables modular assembly and disassembly between the storage layer and the side frame, as well as layered assembly and disassembly design of the storage layer. The plug-in structure simplifies the assembly process, reduces maintenance and replacement costs, and allows users to freely increase or decrease the number of layers and flexibly change the storage space according to their needs.

[0054] The guide groove 305 in this embodiment is composed of two L-shaped plates 3051, one upper and one lower. The two L-shaped plates 3051 are welded to the upper and lower sides of the outer side frame 303, thereby forming the guide groove 305 on the upper and lower edges of the outer side frame 303. Specifically, when the L-shaped plate 3051 is installed on the inner side of the outer side frame 303, the inner side frame 203 slides inside the outer side frame 303; when the L-shaped plate 3051 is installed on the outer side of the outer side frame 303, the inner side frame 203 slides around the outer side frame 303. In this way, the inner side frame 203 of the inner layer 20 can slide directly on the guide groove 305 or slide by adding rollers or slide rails. The L-shaped plate 3051 provides a stable sliding track, reduces frictional resistance, and extends the service life of the telescopic sliding adjustment between the inner layer 20 and the outer layer 30. The double-layer nested design of the inner and outer frames further strengthens the structure and prevents the mesh from deforming.

[0055] Furthermore, several transverse reinforcing plates 306 (such as rectangular steel pipes or channel steel plates) are welded between the outer side frame 303 on the front and rear sides of the outer storage layer 30. The spacing of the reinforcing plates 306 is evenly distributed according to the length of the storage layer. The two ends of the reinforcing plates 306 are welded and fixed to the L-shaped plates 3051 of the guide grooves 305 on the front and rear sides of the outer storage layer 30. In this way, the overall rigidity of the outer storage layer 30 is improved by welding the transverse reinforcing plates 306, avoiding structural distortion caused by expansion and contraction adjustments. At the same time, the structure of the guide grooves 305 is strengthened, and the evenly distributed reinforcing plates 306 disperse the load pressure, improving the maximum load-bearing capacity of the rack.

[0056] In this embodiment, the vertical tubes of the side tube rack assembly are divided into an upper vertical tube 103 and a lower vertical tube 104. The upper diameter of the upper vertical tube 103 is larger than that of the lower diameter, forming a stepped structure. The inner diameter of the sleeve 205 is designed to be narrower at the top and wider at the bottom. The upper end of the upper vertical tube 103 is inserted into the wider end of the sleeve 205, and the lower end is inserted into the narrower end of the sleeve 205 or the upper end of the lower vertical tube 104. In addition, the upper and lower diameters of the lower vertical tube 104 are the same. Its upper end is inserted into the wider end of the sleeve 205, and its lower end passes through the sleeve 205 of another shelf layer and is fixed to the ground by installing foot pads.

[0057] In this way, the stepped vertical tubes and sleeves 205 work together to achieve quick alignment and insertion between the storage layer and the side tube rack, avoiding assembly errors and improving disassembly and assembly efficiency; the foot pad design enhances the stability of the bottom of the shelf and prevents slippage.

[0058] Furthermore, pin holes 1041 are made at the upper and lower ends of the vertical tube, and a conical kit 206 is installed inside the sleeve 205. The conical kit 206 is composed of two assembled pieces 2061 with elastic locking pins 2062. When the vertical tube is inserted, the two assembled pieces 2061 of the conical kit 206 clamp the upper and lower ends of the upper vertical tube 103 and the lower vertical tube 104, respectively, while the locking pins 2062 automatically spring into the pin holes 1041 to lock. When disassembling, the locking pins 2062 can be ejected from the pin holes 1041 by the misaligned sliding of the vertical tube and the locking pins 2062 to complete the separation. In this way, the conical kit 206 provides a tool-free quick assembly and disassembly function, improving the user experience, while the elastic locking pins 2062 ensure the connection is stable and prevent accidental detachment during the use of the shelving.

[0059] The extendable shelving provided in this embodiment allows for quick stacking and storage by inserting the wider ends of the sleeves 205 of the inner and outer shelving layers 20 and 30 into the narrower ends of adjacent layers, stacking them on the bottom shelf. The upper and lower vertical tubes 103 and 104, after disassembly, are placed horizontally on the shelving surface and secured with straps. Therefore, the stacking design maximizes the reduction of shelving volume, minimizing transportation and storage space requirements; the horizontal placement of the vertical tubes prevents parts from scattering and facilitates overall handling.

[0060] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
