Description

Technical Field

[0001] The invention relates to a component connection structure of a bed, in particular to a connection structure between a bed back plate and a bed frame. Background Art

[0002] In the existing field of bed structure, such as Figure 1 As shown, the connection structure between the bed frame and the bed backboard is to install the ear plate assembly 3A at the position for installing the bed backboard 2A on both sides of the bed frame main frame 1A, and rely on the ear plate assembly to carry and connect the bed backboard. However, the installed ear plate will obviously protrude from the outer surface of the bed backboard, destroying the overall simple beauty of the bed. Moreover, in order to ensure the stability of the connection, screws are required for secondary fixation. This cumbersome assembly process not only increases the time cost and manpower investment in the production process, but also greatly reduces the experience of consumers' self-assembly. In addition, the bed backboard is usually made of hollow plastic sheet material, which is prone to flattening or collapse when leaning. If solid plastic sheet material is used, or metal material with better rigidity is adopted, although the stability can be improved, the cost will also increase accordingly. Summary of the invention

[0003] The invention provides a connection structure between a bed back plate and a bed frame which has a simple structure and is convenient and quick to assemble.

[0004] The connection structure between a bed back plate and a bed frame described in the present invention comprises a bed back plate and a frame for supporting the bed back plate, the frame comprising a horizontally arranged cross bar and vertical bars vertically installed at both ends of the cross bar, the bed back plate has a built-in connecting rod that passes through and extends out of both sides, a plurality of protruding plug blocks are provided at the bottom of the bed back plate, the cross bar is provided with a slot that is adapted to be connected with the plug blocks, an "L"-shaped slot is provided at a position opposite to the connecting rod, and a through notch is also provided on the side of the vertical bar for the connecting rod to be smoothly buckled into the slot.

[0005] The connection structure between the bed back plate and the bed frame can realize the quick pre-positioning and preliminary connection of the bed back and the cross bar through the precise cooperation of the plug block at the bottom of the bed back plate and the slot on the cross bar, which provides convenience for subsequent assembly operations; it is convenient for the connecting rods extending from both sides of the bed back plate to align with the through-notches of the slots set in the vertical bars, so that the connecting rods can slide smoothly into the slots. When the connecting rods slide into the slots until the bed back plate is in a vertical state, the bed back plate is gently pressed down to make the connecting rod move down relative to the height of the through-notch and firmly buckle. At the same time, the plug block is further extended into the slot for buckling, so that the close assembly of the bed back plate and the frame can be completed, and the assembly is convenient, fast and safe. The bed backboard is firmly installed; in addition, there is no protruding connection structure on the outer surface of the bed backboard, and only the connecting rods extending from both sides of the bed back are buckled into the vertical rods of the frame, so that the bed backboard and the frame surface are flat, and the overall appearance is flat and simple, which is both practical and ornamental; in addition, the connecting rod runs through the inside of the bed backboard, providing a stable internal support for the leaning part of the bed backboard, which can effectively prevent flattening or collapse caused by leaning, so that the bed backboard can be made of lightweight plastic material with a hollow internal structure without worrying about flattening or collapse. In this way, not only the stability of the bed backboard is increased, but also the production cost is reduced.

[0006] As a preferred solution of the present invention, the bed backboard is provided with extended edges on both sides, the connecting rod is placed on one side of the extended edge, and the length of the end of the connecting rod extending to both sides of the bed backboard is less than the length of the extended edge extending in the same direction, the vertical rod is provided with a retaining edge surrounding and fitting the extended edge, and the horizontal cross-section of the vertical rod is "L" shaped.

[0021] like Figure 2-6 As shown, a connection structure between a bed back plate and a bed frame comprises a bed back plate 1 and a frame 2 for supporting the bed back plate, the frame 2 comprises a horizontally arranged cross bar 201 and vertical bars 202 vertically installed at both ends of the cross bar, the bed back plate 1 has a built-in connecting rod 3 that passes through and extends from both sides, a plurality of protruding plug blocks 101 are provided at the bottom of the bed back plate 1, the cross bar is provided with a slot 203 adapted to be connected with the plug blocks, an "L"-shaped slot 4 is provided at a position opposite to the connecting rod, and a through notch 5 is provided on the side of the vertical rod for the connecting rod to be smoothly buckled into the slot. The connection structure between the bed back plate and the bed frame can realize the quick pre-positioning and preliminary connection of the bed back and the cross bar through the precise cooperation of the plug block at the bottom of the bed back plate and the slot on the cross bar, which provides convenience for subsequent assembly operations; it is convenient for the connecting rods extending from both sides of the bed back plate to align with the through-notches of the slots set in the vertical bars, so that the connecting rods can slide smoothly into the slots. When the connecting rods slide into the slots until the bed back plate is in a vertical state, the bed back plate is gently pressed down to make the connecting rod move down relative to the height of the through-notch and firmly buckle. At the same time, the plug block is further extended into the slot for buckling, so that the close assembly of the bed back plate and the frame can be completed, and the assembly is convenient, fast and safe. The bed backboard is firmly installed; in addition, there is no protruding connection structure on the outer surface of the bed backboard, and only the connecting rods extending from both sides of the bed back are buckled into the vertical rods of the frame, so that the bed backboard and the frame surface are flat, and the overall appearance is flat and simple, which is both practical and ornamental; in addition, the connecting rod runs through the inside of the bed backboard, providing a stable internal support for the leaning part of the bed backboard, which can effectively prevent flattening or collapse caused by leaning, so that the bed backboard can be made of lightweight plastic material with a hollow internal structure without worrying about flattening or collapse. In this way, not only the stability of the bed backboard is increased, but also the production cost is reduced.

[0022] The bed support board 1 is provided with an extension edge 102 on both sides, the connecting rod is placed on one side of the extension edge, and the length of the end of the connecting rod extending to both sides of the bed support board is less than the length of the extension edge extending in the same direction, and the vertical rod 202 is provided with a retaining edge 204 surrounding and fitting the extension edge, and the horizontal cross section of the vertical rod is "L" shaped. The connecting rod is located on one side of the extension edge, and the length of its end extending outward is shorter than the length of the extension edge extending in the same direction, which can ensure that the end of the connecting rod is within the limited range of the extension edge and ensure that the connecting rod can be smoothly buckled into the card slot of the vertical rod; in addition, the retaining edge set on the vertical rod can wrap the bed support board from both sides, which can further make the bed support board and the vertical rod fit tightly, the structure is more stable, and the bed support board and the frame surface can be made more neat.

[0023] The slot 4 is composed of a horizontal transverse slot 401 and a vertical slot 402 extending vertically downward. The transverse slot and the vertical slot are connected to each other to form an "L"-shaped structure. A through notch 5 connected to the transverse slot is provided on the side of the vertical rod to facilitate the connecting rod to buckle into the slot, thereby achieving a close connection between the bed back plate and the vertical rod, and improving assembly efficiency and structural stability.

[0024] The connecting rod 3 is provided with a stopper 6 near the end thereof, which abuts against the side of the bed support board. The stopper can fix the connecting rod inside the bed support board to prevent the connecting rod from moving relative to the bed support board, thereby improving the stability of the structure. Furthermore, the stopper can be a rubber ring or a nut screwed to the connecting rod.

[0025] The inner part of the bed support board 1 is provided with a plurality of concave grooves 7 along the horizontal direction near the upper and lower sides of the connecting rod 3, and the grooves on the upper and lower sides are staggered. Furthermore, the depth of the concave grooves can exceed the center position of the connecting rod, and the grooves on the upper and lower sides of the connecting rod of the bed support board can limit the connecting rod, preventing the connecting rod from falling or rising when passing through the bed support board, ensuring smooth insertion of the bed support board and improving assembly efficiency.

[0026] The inner side of the bed support board 1 is concavely and horizontally provided with strip-shaped limit grooves 8 at the left and right sides near the connecting rod 3. Further, the concave depth of the limit groove can be such that the side wall of the limit groove is flush with the side wall of the connecting rod, or there can be a gap between the side wall of the limit groove and the connecting rod. The strip-shaped limit groove can limit the left and right sides of the connecting rod from the side to support the connecting rod, ensuring that the connecting rod can smoothly pass through the bed support board, further improving the assembly efficiency.
