Description

Technical Field

[0001] This utility model belongs to the field of metal shelf technology, and specifically refers to a shelf column connector. Background Technology

[0002] The main structure of the metal shelving unit consists of several vertical columns and multiple horizontal shelves assembled together. This modular design gives it significant advantages in transportation and storage. Compared to traditional one-piece solid wood furniture, metal shelving units can be flexibly disassembled and reassembled according to usage needs, saving space and facilitating handling, greatly improving ease of use and adaptability.

[0003] For multi-layered metal shelving structures, especially those with more than three layers, longer uprights often become a key factor limiting packaging costs. These shelving units typically require a larger shelf space; therefore, the shelf length is generally designed to be around 1.2 meters, while the uprights, which must extend throughout the entire structure's height, often exceed 1.5 meters in length, significantly larger than the shelf dimensions. This dimensional difference directly leads to packaging challenges, as the uprights, being the longest components, must occupy more space during packaging, thus significantly increasing the package volume. Larger packaging volume not only means the need for more packaging materials but also increases transportation and storage costs, further impacting overall economic efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a shelf column connector to solve the problems existing in the prior art, and to be applied to metal shelf products to splice the upper and lower columns together.

[0005] To achieve the above objectives, the solution of this utility model is: A shelf column connector is made of a metal sheet. The metal sheet is bent into a pair of mutually perpendicular outer plates on the left and right sides of its middle section. A support plate that is bent inward into a horizontal position is formed between the upper and lower ends of the outer plates by stamping, and a locking hole is located on each of the upper and lower sides of the support plate. An arc-shaped connecting part is bent into the outer side of the outer plate, and the end of the arc-shaped connecting part is an inner plate that is parallel to the outer plate.

[0006] The inner plate and the outer plate respectively constitute the limiting part that limits the inner and outer sides of the shelf column, and the upper and lower surfaces of the support plate respectively cooperate with the end faces of the upper and lower columns; the locking hole is used to cooperate with the locking fastener and the mounting hole of the column to achieve locking.

[0007] The inner side of the inner plate is provided with several protrusions.

[0008] Preferably, the protrusions are arranged at equal intervals along the vertical direction.

[0009] The outer side of the outer plate is provided with directional markings to indicate the installation direction of the shelf column connectors.

[0010] The support plate is semi-circular in shape.

[0011] The metal plate has a protrusion on its upper middle surface.

[0012] Preferably, a perforation is provided 1-2 cm below the protrusion.

[0013] After adopting the above technical solution, the present invention has the following technical effects: The outer plates, arc-shaped connecting parts, and inner plates on both sides of the middle of the metal plate component of this utility model each form a groove-shaped structure, giving the entire shelf column connector an approximately V-shaped slot. During assembly, simply insert the upper and lower columns into this slot from the top and bottom respectively. Through a reasonable dimensional design, when the end faces of the upper and lower columns are respectively attached to the upper and lower surfaces of the support plate, ensure that the mounting holes and locking holes are aligned. Then, by using fasteners (such as rivets, bolts, or locks) passing through the mounting holes and locking holes, a stable connection between the upper and lower columns can be achieved, thus splicing short columns into longer ones to meet usage requirements. This connection method is not only simple in structure and convenient to operate, but also effectively ensures connection strength and stability, solving the packaging and transportation problems caused by excessively long columns in existing technologies. At the same time, the design of this connector fully considers the modular characteristics of metal shelves, facilitating disassembly and reassembly, further improving the ease of use and adaptability of metal shelves.

Detailed Implementation

[0019] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0020] refer to Figures 1 to 4 As shown, this utility model discloses a shelf column connector, the raw material of which is a metal plate 100; the middle of the metal plate 100 is bent to form a pair of mutually perpendicular outer plates 101; between the upper and lower ends of the outer plates 101, a support plate 102 is formed by stamping and bending inward to a horizontal position, and a locking hole 103 is located on each of the upper and lower sides of the support plate 102; the outer side of the outer plate 101 (i.e., the side away from the middle of the metal plate 100) is bent into The arc-shaped connecting part 104 has an inner plate 105 at its end that is parallel to the outer plate 101. The inner plate 105 and the outer plate 101 respectively constitute the limiting parts of the inner and outer sides of the limiting shelf column 200. The upper and lower surfaces of the support plate 102 respectively cooperate with the end faces of the upper and lower columns 200 and 200'. The locking hole 103 is used to cooperate with the locking fastener 300 (such as rivets, bolts, buckles and similar locking fasteners) and the mounting hole 201 of the column 200 to achieve locking.

[0021] Through the above solution, the outer plate 101, the arc connecting part 104, and the inner plate 105 on both sides of the middle of the metal plate 100 of this utility model respectively form a groove-shaped structure, so that the entire shelf column connector has an approximately V-shaped slot. During assembly, the upper and lower columns 200 and 200' are simply inserted into the slot from the upper and lower sides respectively. Through reasonable size design, when the end faces of the upper and lower columns 200 and 200' are respectively attached to the upper and lower surfaces of the support plate 102, the mounting hole 201 is aligned with the locking hole 103. Then, by passing the fastener 300 (such as rivets, bolts, or buckles) through the mounting hole 201 and the locking hole 103, a stable connection between the upper and lower columns can be achieved, thereby splicing short columns into longer ones to meet usage requirements. This connection method is not only simple in structure and convenient in operation, but also effectively ensures the connection strength and stability, solving the packaging and transportation problems caused by excessively long columns in the prior art. Meanwhile, the design of this connector also fully considers the modular characteristics of metal shelves, making them easy to disassemble and reassemble, further improving the ease of use and adaptability of metal shelves.

[0022] The following are specific embodiments of the present invention.

[0023] The inner surface of the inner plate 105 is provided with a plurality of protrusions 106, which are evenly spaced along the vertical direction. By providing the protrusions 106, when the columns 200 and 200' are inserted into the slots, the protrusions 106 can increase the friction and prevent the columns from easily sliding in the slots, thereby further enhancing the stability of the connection; moreover, these protrusions 106 can also play a certain positioning role during the assembly of the columns and connectors, making it easier to align the mounting holes 201 and the locking holes 103, thereby improving assembly efficiency.

[0024] The outer side of the outer panel 101 is provided with a direction mark 107 to indicate the installation direction of the shelf column connector, which serves to prevent mistaken installation and facilitates quick installation.

[0025] The aforementioned support plate 102 is semi-circular in shape, ensuring that the corresponding stamped holes are also semi-circular. This design reduces material waste, improves material utilization, and lowers production costs during the stamping process. Simultaneously, the semi-circular support plate 102 provides a relatively uniform stress distribution when bearing pressure from the end faces of the columns 200 and 200', reducing stress concentration and thus enhancing the load-bearing capacity and service life of the connector. Furthermore, the semi-circular design ensures a suitable contact area between the support plate 102 and the end faces of the columns 200 and 200', guaranteeing sufficient support while facilitating installation and disassembly.

[0026] The metal plate 100 has a protrusion 108 on its upper middle surface, and a perforation 109 is provided near the lower part of the protrusion 108 (1-2 cm away). The protrusion 108 provides a larger support area for the upper column 200, especially in scenarios where it needs to support heavy items or where higher local strength of the shelf is required, the protrusion 108 can enhance the overall stability of the shelf. The perforation 109 has multiple uses. On the one hand, it can be used as a hole for installing other accessories (such as hooks, clips, etc.), allowing users to expand the functionality of the shelf according to their actual needs. On the other hand, during the assembly of the shelf, the perforation 109 can also be used as an auxiliary positioning or fixing hole. For example, by inserting pins, the connection accuracy between the shelf column connector and other components can be further ensured, improving the stability of the entire shelf structure.

[0027] In practical applications, the shelving column connector can be manufactured using metal plates 100 of appropriate specifications, depending on the size and requirements of different metal shelving units. For example, for metal shelving units with a large load-bearing capacity and numerous layers, thicker, higher-strength metal plates 100 can be selected to ensure that the connector can withstand sufficient pressure and guarantee the stability of the entire shelving structure. Conversely, for smaller, lighter metal shelving units, relatively thinner, lower-cost metal plates 100 can be used to reduce manufacturing costs while meeting usage requirements.

[0028] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
