[0012] By adopting the above technical solution, all the template horizontal strips of the support plate assembly are connected together by the second Velcro, so that when laying the support plate assembly, there is no need to take and position the wooden horizontal strips one by one, and the assembly is more convenient. At the same time, the structure of the first Velcro and the second Velcro makes the support plate assembly easy to disassemble and replace.

[0013] Preferably, it also includes two longitudinal parts in the bed, which include a longitudinal tube in the bed and connectors fixed at both ends of the longitudinal tube in the bed, a socket is fixed in the middle of the head of the bed horizontal tube towards the end of the bed, sockets are fixed on both sides of the middle of the transverse tube in the bed, and a socket is fixed in the middle of the end of the bed horizontal tube towards the head of the bed.

[0016] By adopting the above technical solution, the fixing plate is used as the welding fixing surface of the plug-in component, and the inclined guide plate part formed by the bending of the fixing plate below the bending joint cooperates with the inclined pressure plate part on the socket, so that the bed frame always bears the vertical force during use. The matching part of the inclined guide plate and the inclined pressure plate is continuously compressed under the vertical force, so that the connection of the bed frame becomes tighter after continuous use. The spacing between the two inclined guide plates and the two inclined pressure plates ensures that even if the plug-in component and the socket are slightly deformed during the welding process, it can still be compensated by squeezing the two inclined guide plates closer together or squeezing the two inclined pressure plates apart. The deformed plug-in component can not only be inserted into the socket, but also can fit tightly with the inner wall of the socket after deformation adjustment.

[0017] Preferably, it also includes a bedside frame assembly, the bedside frame assembly includes two plug-in components, the bedside support component includes a bedside support column made of a square tube, and socket components are fixed on three adjacent surfaces of the bedside support column.

A plurality of adjusting holes penetrating the headboard panel are evenly distributed along the length direction on the vertical square tubes, and two through holes are spaced apart on the adjusting square tube. The position of the adjusting square tube and the relative position of the vertical square tube are fixed by fasteners passing through the two through holes and the adjusting holes, and two connectors are respectively fixed on the two adjusting square tubes.

[0020] By adopting the above technical solution, other parts of the bed frame can be placed in the internal space of the headboard frame assembly after being disassembled, and the adjustable square tube can also be put into the internal space, making it more convenient to store, pack and transport. At the same time, the distance between the headboard side plate and the headboard crosspiece can be changed by aligning and fixing the perforations of the adjustable square tube with different adjustment holes to adapt to mattresses of different thicknesses.

[0021] Preferably, the plug-in connector includes a welding section and an insertion section, the welding section is U-shaped, and both ends of the U-shape are located in the same plane for welding and fixation, the insertion section is a funnel-shaped integrally formed with the welding section, and one side of the insertion section is formed with a first breaking opening that runs through the entire insertion section; the socket connector is a funnel-shaped whose size gradually decreases from top to bottom, and one side of the socket connector is formed with a second breaking opening that runs through the entire socket connector.

[0022] By adopting the above technical solution, the plug-in and the socket are both arranged in a funnel-shaped structure, so that the plug-in and the socket are continuously pressed by the longitudinal force during use, so the bed frame will become more and more stable during use. At the same time, the arrangement of the first breaking point and the second breaking point ensures that even if the plug-in and the socket are slightly deformed during the welding process, they can still adapt to the deformation through the cooperation of the first breaking point and the second breaking point.

[0024] By adopting the above technical solution, the upper and lower ends of the insertion section and the sleeve are set to be tangent to the outer ring projection, so that the sleeve can be directly welded and fixed through this side without setting other additional structures. On the one hand, the processing difficulty of the sleeve is reduced, and on the other hand, the deformation error caused by the sleeve welding is reduced, and the installation difficulty caused by the angle deviation of the insertion fit is reduced. The position and angle of the sleeve during welding are ensured by the design of the positioning groove.

[0025] Preferably, the connector includes a transition plate, two fixed plates connected on both sides of the transition plate and perpendicular to the transition plate, the middle parts of the two fixed plates away from one end of the transition plate are formed with a bending connection notch, and the part of each fixed plate located below the bending connection notch is bent to form an inclined guide plate, the inclined guide plate is inclined from top to bottom toward the direction close to the transition plate, and a gap is left between the lower end of the inclined guide plate and the transition plate, the two inclined guide plates are located in the same plane, and a gap is left between the two inclined guide plates; the socket includes a bonding plate, the bonding plate Both sides of the extension plate are bent to form an extension plate, the extension plate is a right-angled triangle, and the side where the extension plate is connected to the bonding plate and the upper side of the extension plate are its right-angled sides.

[0026] By adopting the above technical solution, the spacing between the two inclined guide plates and the two inclined pressure plates ensures that even if the connector and the socket are slightly deformed during the welding process, the two inclined guide plates can still be squeezed together or the two inclined pressure plates can be squeezed apart to compensate. The deformed connector can not only be inserted into the socket, but also fit tightly with the inner wall of the socket after deformation adjustment. The lower end of the extension plate is welded and fixed to the inclined pressure plate, and a spacing is left between the lower part of the inclined guide plate and the transition plate. On the one hand, it avoids the situation that the insert cannot be smoothly inserted into the socket due to processing errors and deformation after welding; on the other hand, during the process of inserting the connector into the socket after the bed frame is assembled, even if deformation occurs during long-term use, the deformation will stop when the inclined guide plate is squeezed to fit the transition plate, and the bed frame will not drop significantly, or a certain support point will be deformed to cause the bed frame to tilt.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

The bed frame of the present application solution can be assembled by simply plugging in, without the need to use special tools to operate, which makes assembly more convenient and eliminates a series of problems caused by untightened bolts. At the same time, the plug-in structure makes the connection of the bed frame more and more reliable during practical use. BRIEF DESCRIPTION OF THE DRAWINGS
