[0001] This utility model belongs to the field of profile technology, specifically relating to a sheet metal splicing structure. Background Technology

[0002] Boards are widely used in wall, ceiling, floor and various decorative board fields. In the process of use, splicing is often required to achieve large-area laying or specific size adaptation.

[0003] The patent disclosed in CN216713667U discloses a panel splicing mechanism that achieves a detachable connection between the first panel, the second panel, and the splicing device by directly interlocking the two ends of the splicing device with the splicing grooves of the first panel and the second panel, respectively. This eliminates the need for welding or riveting, and does not produce burrs, flash, or mounting holes during production. It simplifies the process, reduces labor costs, and improves the product appearance.

[0004] During long-term use, the aforementioned panel splicing mechanism is prone to loosening at the splicing points due to insufficient adaptability of the connection structure, which in turn affects the stability and service life of the splicing structure. Utility Model Content

[0034] Example 1:

[0035] See appendix Figures 1-2 As shown in the figure, an embodiment of the present invention provides a board splicing structure, including a connector 100, an inner connector 200 and an outer connector 300. The connector 100 is disposed between two adjacent boards 1, and two inner connectors 200 are symmetrically arranged on the connector 100.

[0036] The outer connector 300 is disposed on the plate 1, and is arranged in a one-to-one correspondence with the inner connector 200; the inner connector 200 includes a transition portion 210 fixedly connected to the side of the connector 100, and a limit hook is fixedly connected to the side of the transition portion 210 away from the connector 100.

[0037] The external connector 300 includes a transition groove 310 formed on the side of the plate 1 and adapted to the transition portion 210. One side of the inner cavity of the transition groove 310 is provided with a limiting groove for use with the anti-detachment component.

[0038] In the above technical solution, the transition part 210 and the limiting hook of the inner connector 200 and the transition groove 310 and the limiting groove of the outer connector 300 are correspondingly matched to achieve a detachable and reliable connection between adjacent plates 1. This avoids the complex process problems caused by traditional welding and riveting from the basic structure. With the connector 100 as the intermediate connecting carrier, the connection between adjacent plates 1 is achieved through the precise adaptation of the inner connector 200 and the outer connector 300. At the same time, it provides a stable foundation for subsequent structural optimization.

[0039] During splicing, one end of the connector 100 is placed at the ends of the two plates 1 to be spliced, so that the symmetrically arranged inner connectors 200 on the connector 100 correspond one-to-one with the outer connectors 300 on the side of the plate 1. The two plates 1 to be spliced ​​are pressed and fixed. Then the connector 100 is pushed in, so that the connector 100 drives the transition part 210 of the inner connector 200 to be inserted into the transition groove 310 of the outer connector 300. The protrusions A220 and B230 are inserted into the hook grooves A320 and B330 in sequence. The self-locking characteristics of the trapezoidal structure are used to form a stable double snap-fit, thus completing the splicing and fixing of the plate 1.

[0040] After splicing, the reinforcing strip 400 inside the cavity of the connector 100 and the inner connector 200 enhances the deformation resistance of key parts and prevents damage to the splice joint due to stress.

[0041] To achieve lightweight design while ensuring strength, the limiting hook includes a protrusion A220 fixedly connected to the outside of the transition portion 210, and a protrusion B230 on the other side of the protrusion A220. The inner cavities of the connector 100, the transition portion 210, and the protrusion A220 are interconnected. This combined limiting hook structure of protrusions A220 and B230 extends the engagement stroke of the inner connector 200, and the interconnected structure of the inner cavities of each component simplifies the manufacturing process and improves the structural rationality of the inner connector 200.

[0042] To further enhance the tightness of the engagement between the inner connector 200 and the outer connector 300, the limiting groove includes a hook groove A320 that is formed in the inner cavity of the transition groove 310 and is adapted to the protrusion A220. A hook groove B330 that is adapted to the protrusion B230 is formed on one side of the inner cavity of the hook groove A320. The transition groove 310, hook groove A320 and hook groove B330 are interconnected. The protrusion B230 is engaged in the inner cavity of the hook groove B330 and the protrusion A220 is engaged in the inner cavity of the hook groove A320. A combined limiting groove of hook groove A320 and hook groove B330 is provided corresponding to the limiting hook, so that the protrusion A220 and the protrusion B230 form a double engagement with the hook groove A320 and the hook groove B330 respectively, which significantly improves the anti-detachment ability of the splicing structure of the board.

[0043] To prevent lateral displacement at the joint and improve connection stability, the inner cross-sections of hooks A220, B230, A320, and B330 are all trapezoidal. The short lateral straight side of hook A220 connects to the long longitudinal straight side of hook B230, with the short lateral straight side of hook A220 being shorter than that of hook B230. The long longitudinal straight side of hook A220 connects to transition section 210, with the long longitudinal straight side of hook A220 being longer than that of hook B230. The distance between the two long straight sides of hook A220 is greater than the distance between the two long straight sides of hook B230. The trapezoidal cross-section allows the limiting hook and limiting groove to form a guiding snap-fit, facilitating precise alignment during installation. Simultaneously, the inclined surface characteristic of the trapezoidal structure creates a self-locking effect after snap-fit.

[0044] To address the issue of concentrated stress and easy deformation at the joint and extend the service life of the structure, both the connector 100 and the hook A220 are equipped with reinforcing strips 400 in their inner cavities. The reinforcing strips 400 and the short straight sides of the hook A220 are arranged parallel to each other to precisely enhance the bending strength of the connection between the inner connector 200 and the connector 100.

[0045] To improve the structural adaptability to different scenarios, the outer side of the connector 100 is flush with the outer side of the board 1, while the other outer side of the connector 100 is recessed compared to the other outer side of the board 1. This differentiated design of the connector 100, which is flush with and recessed, ensures the flatness of one side of the board 1 after splicing, meeting the appearance requirements, while also reserving operational space for subsequent decoration and accessory installation on the other side.

[0046] Example 2:

[0047] See appendix Figures 3-4 As shown, this embodiment of the utility model provides a plate splicing structure, which differs from Embodiment 1 in that:

[0048] The connector 100 has symmetrical support bars 110 on its outer side, flush with the plate 1. The inner wall of the support bars 110 is in contact with the surface of the plate 1. The support bars 110, connector 100, transition part 210, and protrusions A220 and B230 are integrally formed. The integrally formed structure eliminates assembly gaps and connection errors between components, making the support bars 110, connector 100, and inner connector 200 a mechanical whole. This not only improves the overall strength and stability of the structure but also simplifies the production process and reduces processing costs.

[0049] The above-mentioned technical solution's panel splicing structure consists of connector 100, support strip 110, inner connector 200, outer connector 300, and reinforcing strip 400. The support strip 110's close fit to the surface of the panel 1 can transfer the weight of the panel 1 and external forces to the connector 100, thereby dispersing the force and preventing the panel 1 from deforming or breaking due to excessive force at a single point, thus playing an auxiliary protective role for the panel 1.

[0050] In summary, the panel splicing structure of this utility model embodiment forms a precisely matched snap-fit ​​structure through the limiting hook of the inner connector 200 and the limiting groove of the outer connector 300, which improves the anti-detachment performance at the splicing point between two adjacent panels 1; at the same time, the support strip 110 forms a close-fitting support for the spliced ​​panels 1, dispersing the weight of the panels 1 themselves and external pressure, avoiding problems such as bending and breakage of the panels 1 due to uneven stress, and extending the service life of the panels 1.

[0051] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
