Description

Technical Field

[0001] This utility model relates to the field of connecting structures and storage devices, specifically an adjustable connecting rod and a storage rack. Background Technology

[0002] There are many unresolved issues in existing connection structures and shelving products. Traditional connecting rods are mostly of fixed length and structure, making it difficult to flexibly adjust them according to actual usage needs. When it is necessary to change the height or width of the shelving or to perform diverse assembly, the fixed structure of the connecting rods cannot meet this requirement, forcing users to purchase various sizes of shelving, increasing costs and wasting resources.

[0003] In the field of shelving, common shelving support structures are not stable enough. Some shelving units have simple connections between support rods and connecting rods, making them prone to loosening, deformation, or even breakage under heavy loads, severely impacting the lifespan and safety of the shelving unit. At the same time, the connection between the shelf and the support frame is often not tight enough, making it prone to displacement during daily use and causing instability of placed items.

[0004] Furthermore, the selection of materials for existing shelving units also has certain limitations. Some shelving units use ordinary materials, making it difficult to achieve a balance between strength and lightweight. For example, some metal shelving units, while strong, are too heavy, making them inconvenient to move and install; while some plastic shelving units, although...

[0005] While lightweight, they lack strength and cannot support heavy items. This makes it difficult for users to find a storage rack that meets both load-bearing requirements and ease of use. Utility Model Content

[0006] The present invention aims to solve the above-mentioned technical problems by providing an adjustable connecting rod and a shelf, which is suitable for home, office and industrial storage scenarios that require flexible assembly, adjustable structure and a certain load-bearing capacity.

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: an adjustable connecting rod, comprising: L-shaped cross-section uprights have inverted gourd-shaped holes arranged in an array on their surface, and folded edges on both sides. The upper diameter of the gourd-shaped holes is 2-3mm larger than the lower diameter to form a snap-fit ​​anti-reverse structure. L-shaped cross-section connector, with mounting hole group and edge-sealing structure matching the hole spacing of the hoist; The connector is axially limited and connected to the folded edge at the end of the upright through the edge-wrapping structure; A fixing snap is provided between the gourd hole and the mounting hole group.

[0008] A shelf using an adjustable connecting rod includes: Four support rods, the support rods having a V-shaped stepped cross-section, and their ends having positioning protrusions made of elastic metal material. The diameter of the protrusions is smaller than the upper diameter of the gourd hole but larger than the lower diameter. The transverse connecting rod has mounting shafts at both ends that are interference-fitted with the limiting holes of the support rod, forming a rectangular support frame; A honeycomb aluminum shelf is mounted on a rectangular support frame, and its bottom surface has a guide groove that fits into the V-shaped stepped surface of the support rod.

[0009] Furthermore, the ribs on the outer surface of the L-shaped cross-section upright have a height of 1.2-1.5 times the wall thickness of the L-shaped cross-section upright, and the cross-section of the ribs is a semi-circular structure.

[0010] Furthermore, the ribs are integrally formed with the L-shaped cross-section upright body.

[0011] The advantages of this utility model compared with the prior art are as follows: 1. The adjustable connecting rod design makes the assembly of the shelf more flexible. Users can freely adjust the length and angle of the connecting rod according to the actual space and usage needs, thereby realizing changes in dimensions such as the height and width of the shelf, greatly improving the versatility and adaptability of the shelf.

[0012] 2. The folded edges of the uprights, the ribs, and the edging structure of the connectors work together to enhance the strength and stability of the entire structure. The connection method between the support rods and the horizontal connecting rods, as well as the fitting method between the shelf and the support frame, enable the shelf to withstand greater weight, making it less prone to deformation or loosening, thus extending the shelf's service life.

[0013] 3. The storage rack uses a honeycomb aluminum platform, which reduces the overall weight while ensuring sufficient load-bearing capacity. The honeycomb aluminum material has a good strength-to-weight ratio, making the rack easy to move and install while meeting the load-bearing requirements of daily use.

[0014] 4. The installation of the shelf is simple and quick thanks to the fit between the gourd hole and the positioning protrusion, as well as the interference fit between the horizontal connecting rod and the support rod. Disassembly is also convenient, facilitating storage and transportation. Attached Figure Description

Detailed Implementation

[0025] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly, for example, it can be a fixed connection, a detachable connection, or an integral connection; for those skilled in the art, the specific meaning of the above term in this utility model can be understood according to the specific circumstances.

[0027] I. Working principle of this utility model: Adjustable connecting rod The adjustable connecting rod of this utility model is mainly composed of an L-shaped cross-section upright and an L-shaped cross-section connector.

[0028] L-shaped cross-section upright: The upright surface is arrayed with inverted gourd-shaped holes. The unique design of these holes is one of the key features of this invention; the upper hole diameter is 2-3mm larger than the lower hole diameter, creating a snap-fit ​​anti-reverse structure. The folded edges on both sides not only enhance the structural strength of the upright but also provide a foundation for connection with the connectors. Ribs are also provided on the outer surface of the upright. The rib height is 1.2-1.5 times the wall thickness of the L-shaped cross-section upright, and the rib cross-section is semi-circular. Furthermore, the ribs are integrally formed with the L-shaped cross-section upright body. The ribs significantly improve the load-bearing capacity and stability of the upright, while the integral forming process ensures the integrity and strength of the structure.

[0029] L-shaped cross-section connector: The connector is equipped with a set of mounting holes that match the spacing of the hoist holes and an edge-sealing structure. A fixing snap is provided between the hoist holes and the mounting hole set. The edge-sealing structure forms an axial limiting connection with the folded edge at the end of the upright. This connection method allows the connector to be adjusted along the axial direction of the upright. After adjustment to the appropriate position, stable fixing is achieved through the cooperation of the hoist holes, the mounting hole set, the fixing snap, and the snap-fit ​​anti-reverse structure.

[0030] Shelves with adjustable connecting rods Support rods: The shelf consists of four support rods with a V-shaped stepped cross-section. Springs are provided at the ends.

[0031] The positioning protrusion is made of a metallic material, with a diameter smaller than the upper diameter of the gourd hole but larger than the lower diameter. This design allows the support rod to be quickly and stably connected to the gourd hole on the upright through the positioning protrusion, and it will not easily fall off after connection.

[0032] Lateral connecting rod: The two ends of the lateral connecting rod are equipped with mounting shafts that are interference-fitted with the limiting holes of the support rod. This interference fit forms a rectangular support frame, which ensures the structural stability of the support frame.

[0033] Honeycomb aluminum shelf: The shelf is set on a rectangular support frame, and the bottom surface has a guide groove that fits into the V-shaped stepped surface of the support rod. This fitting method allows the shelf to be placed stably on the support frame and will not shift when items are placed on it.

[0034] II. Implementation Method: Fabrication and installation of adjustable connecting rods L-shaped cross-section pole fabrication: Select a suitable metal material, such as aluminum alloy, and fabricate the L-shaped cross-section pole using an extrusion molding process. During extrusion, surface ribs are simultaneously formed, ensuring the ribs are integrally formed with the pole body. Then, using drilling equipment, inverted gourd-shaped holes are drilled on the pole surface in a predetermined array, controlling the upper diameter of the gourd-shaped holes to be 2-3mm larger than the lower diameter. Finally, the two sides of the pole are folded to form the folded edges.

[0035] L-shaped cross-section connector fabrication: Based on the dimensions of the upright and the hole spacing of the hoist, L-shaped cross-section connectors are fabricated using a stamping process. Mounting holes matching the hoist hole spacing are punched into the connectors, and an edge-sealing structure is fabricated at the ends.

[0036] Installation process: Align the edge of the L-shaped cross-section connector with the folded edge at the end of the L-shaped cross-section pole, and slide it axially to select a suitable position. Then, secure it by passing the snap fasteners through the mounting hole group and the corresponding gourd hole. During adjustment, utilize the locking mechanism of the gourd hole to prevent accidental slippage of the connector.

[0037] Assembly of the storage rack Support rod preparation: Use metal processing equipment to process the metal material into a support rod with a V-shaped stepped structure, and install a positioning protrusion made of elastic metal material at the end of the support rod.

[0038] Lateral Link Preparation: Fabricate lateral links with mounting shafts at both ends, ensuring the dimensions of the mounting shafts match... The limiting hole of the support rod can achieve an interference fit.

[0039] Support frame assembly: Insert the mounting shaft of the transverse connecting rod into the limiting hole of the support rod, and assemble it into a rectangular support frame by interference fit.

[0040] Connecting the upright to the support frame: Align the positioning protrusion at the end of the support rod with the hoist hole on the upright, press the support rod down to engage the positioning protrusion into the hoist hole, thus completing the connection between the upright and the support frame. Hoist holes at different locations can be selected for connection according to the required height.

[0041] Installation of the shelf: Align the guide groove on the bottom of the honeycomb aluminum shelf with the V-shaped step surface of the support rod, and slowly lower the shelf so that the guide groove fits into the V-shaped step surface to complete the assembly of the shelf.

[0042] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
