Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector buckle. Background Technology

[0002] In existing shelving systems (such as shelves, display racks, industrial supports, etc.), the side panels or center panels between two uprights are typically fixed using traditional mechanical connections, such as bolts, screws, or metal clips. This type of connection presents the following technical challenges:

[0003] Low installation efficiency: Traditional screw fixing requires pre-drilling holes and tightening each screw individually, which is cumbersome and time-consuming, especially in large-scale assembly scenarios. For example, a single partition requires multiple screws, making installation tools highly dependent and unable to achieve rapid assembly and disassembly.

[0004] Limited compatibility: Different board thicknesses (such as 12mm, 18mm, 25mm, etc.) require different specifications of connectors or adjustment hole designs, resulting in a wide variety of accessories, complex inventory management, and inability to adapt to customized board requirements.

[0005] Insufficient structural stability and durability: Metal screws are prone to loosening due to vibration or load after long-term use and require regular maintenance; while some plastic clips are prone to breakage or elastic failure due to unreasonable elastic design, resulting in the plate not being firmly fixed.

[0006] Material and cost issues: Metal connectors increase the overall weight and cost, while pre-drilled holes for screws may weaken the strength of the sheet metal, especially in thin sheet metal (such as 12mm) applications, which may lead to cracking risks.

[0007] In recent years, although some screwless snap-fit ​​solutions have been proposed, most of them use a single boss or rigid snap-fit ​​structure, which is difficult to adapt to various sheet thicknesses and can easily cause permanent deformation of plastic parts during disassembly. For example, some snap-fits are only optimized for 15mm or 20mm sheet materials and cannot cover a wider range of thicknesses through elastic deformation, resulting in poor versatility.

[0008] Therefore, there is an urgent need for a screwless, adaptable, and highly reliable flexible snap-fit ​​connection solution to simplify the frame assembly process, reduce maintenance costs, and improve structural adaptability. This invention was developed in this context. Utility Model Content

[0009] The purpose of this invention is to provide a connecting buckle to achieve a boltless connection between the column and the plate.

[0010] This utility model is achieved using the following technical solution: a connecting buckle, characterized in that it includes a buckle body, one side of which is provided with a connecting post for insertion into a side hole of a vertical plate, and the other side is provided with a connecting plate. A protruding locking block is provided on the outer side of the connecting plate. One end of the connecting plate is elastically connected to the buckle body via an elastic connecting section. A groove is formed in the buckle body at a corresponding position on the connecting plate. The groove accommodates the connecting plate and allows it to float on both sides of the plane where the end face of the buckle body is located via the elastic connecting section. This structure, through the cooperation of the floating connecting plate and the elastic connecting section, enables the buckle to self-adjust during installation, achieving rapid locking of the locking block and the mounting groove without precise alignment, significantly improving installation efficiency and adapting to the compatibility requirements of different plate thicknesses.

[0011] Furthermore, the elastic connecting section, the buckle body, and the connecting plate are integrally molded structures made of elastic plastic material. This integral molding design avoids the risk of parts loosening associated with traditional assembled buckles. Simultaneously, the elastic properties of plastic ensure that the buckle maintains stable elastic recovery during repeated assembly and disassembly, extending its service life.

[0012] Furthermore, the elastic connecting section is a semi-circular arc-shaped extension structure, with one end connected to the buckle body and the other end connected to the connecting plate. This semi-circular arc-shaped extension structure undergoes elastic deformation under pressure. The semi-circular arc structure can evenly distribute external force between the connecting plate and the buckle body, reducing stress concentration and preventing the elastic connecting section from breaking due to excessive local deformation. It also provides a greater elastic stroke, ensuring reliable engagement of the buckle block within the mounting groove.

[0013] Furthermore, the depth of the groove is configured such that when the connecting plate is fully pressed into the groove, the locking block does not protrude from the end face of the buckle body. This design prevents accidental collision damage to the locking block during transportation or when not in use, while ensuring no interference when the buckle body is fitted with the column, reducing installation resistance and improving operational smoothness.

[0014] Furthermore, the connecting plate is inclined relative to the end face of the buckle body in its natural state, and the connection point between the connecting plate and the elastic connecting section is lower than its free end. During installation, the inclination of the connecting plate decreases due to the pressure of the column, and the connecting plate returns to parallel with the end face of the buckle body after the buckle block enters the mounting groove. The inclined connecting plate can automatically adjust its angle through elastic deformation during installation, and the squeezing action of the column guides the buckle block to accurately enter the mounting groove without manual intervention, simplifying the installation steps and reducing the risk of operational errors.

[0015] Furthermore, the column is provided with a mounting groove that mates with the locking block. The mounting groove is located on the side wall of the column, and its width is adapted to the size of the locking block to limit the lateral displacement of the upright plate. The tight fit between the width of the mounting groove and the locking block can effectively prevent the upright plate from shifting or swaying under load, ensuring the overall stability of the frame system, which is especially suitable for high load-bearing scenarios.

[0016] Furthermore, the thickness of the buckle body matches the gap between the upright plate and the column. By precisely matching the gap size, the buckle can completely fill the gap between the upright plate and the column after installation, eliminating vibration or abnormal noise problems caused by excessive gaps, while improving the overall aesthetics and safety of the frame structure.

[0017] The connecting buckle described in this utility model has the following advantages:

[0018] Through the coordinated design of flexible connecting sections and floating connecting plates, an efficient and reliable connection between the uprights and columns in the frame system is achieved. The flexible connecting section adopts a semi-circular arc-shaped one-piece molding structure, which evenly distributes stress under pressure, avoiding localized breakage. Simultaneously, the elastic recovery characteristics of the plastic material ensure that the buckle maintains stable engagement force after repeated disassembly and assembly, significantly extending its service life. The floating adjustment capability of the connecting plate can adapt to different thicknesses of sheet metal. Combined with the tight fit between the buckle and the mounting groove, it eliminates the cumbersome process of traditional screw fixing, enabling tool-free rapid installation, and effectively limits the lateral displacement of the uprights, enhancing the load-bearing stability of the frame. Furthermore, the thickness of the buckle body is precisely matched to the gap between the uprights and columns, and the hidden groove design avoids damage to the buckle during transportation and reduces installation resistance, ensuring smooth operation. This solution significantly reduces material and processing costs through lightweight one-piece plastic molding technology, while possessing excellent corrosion resistance and modular expansion capabilities. It can adapt to the flexible modification needs of various scenarios such as shelves and display racks, combining practicality and economy. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Example

[0025] like Figure 1-2 As shown, a connecting buckle includes a buckle body 1, a connecting post 3 on one side of the buckle body 1, a connecting plate 2 on the other side, a protruding locking block 4 on the outer side of the connecting plate 2, and one end of the connecting plate 2 is elastically connected to the buckle body 1 through an elastic connecting section 5.

[0026] The buckle body 1 has a groove at a corresponding position on the connecting plate 2. The groove accommodates the connecting plate 2 and allows the connecting plate 2 to float back and forth on both sides of the plane where the end face of the buckle body 1 is located under the action of the elastic connecting section 5. The connecting plate 2 is initially located outside the end face of the buckle body 1.

[0027] The connection between the upright plate 6 and the column 7 is achieved through the buckle. The upright plate 6 has holes on its side that mate with the connecting column 3, and the column 7 has mounting grooves 8 that mate with the locking block 4. In actual installation, the buckles are first installed on both sides of the upright plate 6, and then the upright plate 6 is pushed between the two columns 7. When the locking block 4 moves to the mounting groove 8, it is locked into the mounting groove 8 by the action of the elastic connecting section 5 to achieve fixation. Example

[0028] This embodiment is a further optimization based on Embodiment 1, specifically:

[0029] The elastic connecting section 5, the buckle body 1, and the connecting plate 2 are integrally formed. One end of the connecting plate 2 extends along a semi-circular arc and connects to the buckle body 1. This semi-circular arc structure is the elastic connecting section 5. The groove depth of the buckle body 1 should ensure that the buckle block 4 does not protrude from the end face of the buckle body 1 after the connecting plate 2 is pressed down. The gap between the upright plate 6 and the upright column 7 is the same as the thickness of the buckle body 1.

[0030] The connecting plate 2 remains tilted under the action of the elastic connecting section 5. The connection between the connecting plate 2 and the elastic connecting section 5 is lower than the free end of the connecting plate 2. When the upright plate 6 is pushed between the two uprights 7, the elastic connecting section 5 is pushed inward. The tilt of the connecting plate 2 gradually decreases due to the pressure of the uprights 7. When the locking block 4 enters between the upright plate and the upright 7, the tilt angle of the connecting plate 2 becomes a negative angle. When the locking block 4 is inserted into the mounting groove 8, the connecting plate 2 returns to being parallel to the end face of the buckle body 1.

[0031] The above embodiments describe the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Modifications and variations made by those skilled in the art without departing from the spirit and scope of this utility model should be protected within the scope of the appended claims.
