Description

Technical Field

[0001] This utility model relates to a component connection structure for a bed, specifically a connection structure between a headboard and a bed frame. Background Technology

[0002] In the existing field of bed structure, such as Figure 1 As shown, the connection structure between the bed frame and the headboard involves installing ear plate assemblies 3A on both sides of the main bed frame 1A at positions used for mounting the headboard 2A. These ear plate assemblies support and connect the headboard. However, the installed ear plates protrude noticeably from the outer surface of the headboard, disrupting the overall minimalist aesthetic of the bed. Furthermore, to ensure stability, screws are required for secondary fixing. This cumbersome assembly process not only increases production time and manpower but also significantly diminishes the consumer's experience of DIY assembly. In addition, headboards are typically made of hollow plastic sheets, which are prone to flattening or collapsing when leaned against. While using solid plastic sheets or a more rigid metal material would improve stability, the cost would also increase accordingly. Utility Model Content

[0021] like Figures 2-6 As shown, a connection structure between a headboard and a bed frame includes a headboard 1 and a frame 2 for supporting the headboard. The frame 2 includes a horizontally arranged crossbar 201 and vertical bars 202 installed at both ends of the crossbar. The headboard 1 has a connecting rod 3 that extends through and out to both sides. The bottom of the headboard 1 has several protruding inserts 101. The crossbar has slots 203 that are adapted to mate with the inserts. The vertical bars have "L"-shaped grooves 4 at positions opposite to the connecting rods. The side of the vertical bars also has through notches 5 for the connecting rods to be smoothly engaged in the grooves. The aforementioned connection structure between the headboard and the bed frame utilizes a precise fit between the insert at the bottom of the headboard and the slot on the crossbar, enabling pre-positioning and initial connection of the headboard and crossbar, facilitating subsequent assembly. This allows the connecting rods extending from both sides of the headboard to align with the through-holes in the slots on the vertical bar, enabling the connecting rods to slide smoothly into the slots. Once the headboard is vertical, gently pressing down on the headboard lowers the connecting rods relative to the through-holes, securing them firmly. Simultaneously, the insert further extends into the slot for further engagement, completing the tight assembly of the headboard and frame. This assembly is convenient, quick, and safe. The headboard is securely installed. Furthermore, the outer surface of the headboard has no protruding connecting structures; only internal connecting rods extending from both sides of the headboard and fastening into the vertical bars of the frame, ensuring the headboard and frame surfaces are flat and clean, combining practicality and aesthetics. In addition, the connecting rods penetrate the headboard from within, providing stable internal support for the leaning parts, effectively preventing flattening or collapse due to leaning. This allows the headboard to be made of lightweight plastic material with a hollow internal structure without worrying about flattening or collapse. This not only increases the stability of the headboard but also reduces production costs.

[0022] The two sides of the bed backrest 1 are provided with extension edges 102, the connecting rods are arranged on one side of the extension edges, and the lengths of the end portions of the connecting rods extending outwards to the two sides of the bed backrest are less than the lengths of the extension edges extending in the same direction. The vertical rod 202 is provided with a blocking edge 204 wrapping around the extension edge, and the horizontal cross section of the vertical rod is in the shape of "L". The connecting rod is arranged on one side of the extension edge, and the length of the end portion extending outwards is less than the length of the extension edge extending in the same direction, so that the end portion of the connecting rod is ensured to be within the limited range of the extension edge, and the connecting rod can be smoothly buckled into the clamping groove of the vertical rod. In addition, the blocking edge of the vertical rod can wrap around the bed backrest from both sides, so that the bed backrest and the vertical rod are tightly fitted, the structure is more stable, and the bed backrest and the frame surface are more neat.

[0023] The clamping groove 4 is composed of a horizontal transverse groove 401 and a vertical groove 402 extending downwards, the transverse groove and the vertical groove are in communication with each other, forming an "L" shaped structure, the side edge of the vertical rod is provided with a through gap 5 in communication with the transverse groove, facilitating the buckling of the connecting rod into the clamping groove, realizing the tight connection of the bed backrest and the vertical rod, and improving the assembly efficiency and structural stability.

[0024] The connecting rod 3 is sleeved with a limiting piece 6 abutting against the side edge of the bed backrest at a position close to the end portion, the connecting rod can be fixed in the bed backrest by the limiting piece, preventing the relative movement of the connecting rod relative to the bed backrest, thereby improving the stability of the structure. Further, the limiting piece can be a rubber ring or a nut screwed with the connecting rod.

[0025] A plurality of concave grooves 7 are arranged horizontally and transversely in the bed backrest 1 inside, close to the upper and lower sides of the connecting rod 3, and the grooves on the upper and lower sides are arranged in a staggered manner. Further, the depth of the concave groove can exceed the center position of the connecting rod, and the grooves on the upper and lower sides of the bed backrest can limit the connecting rod, preventing the connecting rod from being misaligned by falling or rising when passing through the bed backrest, ensuring smooth passing through the bed backrest and improving the assembly efficiency.

[0026] A strip-shaped limiting groove 8 is arranged horizontally and transversely in the bed backrest 1 inside, close to the left and right sides of the connecting rod 3. Further, the depth of the limiting groove can be that the side wall of the limiting groove is flush with the side wall of the connecting rod, or there is a gap between the side wall of the limiting groove and the connecting rod. The strip-shaped limiting groove can limit and press the left and right sides of the connecting rod from the side, ensuring that the connecting rod can smoothly pass through the bed backrest, and further improving the assembly efficiency.
