[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. The technical features designed in the different implementations of this application described below can be combined with each other as long as they do not conflict with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0034] In the description of this application, it should be noted that all terms used in this application (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains, and should not be construed as limiting this application; it should be further understood that the terms used in this application should be understood to have the same meaning as those in the context of this specification and the relevant field, and should not be understood in an idealized or overly formal sense, except as expressly defined in this application.

[0035] This application provides, as follows: Figure 1-11 The detachable bed frame shown in the embodiment has the following technical solution:

[0036] The detachable bed frame includes a head and tail assembly 100, side assemblies 200 located on both sides of the head and tail assembly 100, and a support assembly 300 for supporting the head and tail assembly 100 and the side assemblies 200.

[0037] The head and tail assembly 100 includes a headboard strip 110 and a footboard strip 120 arranged opposite to each other. The side assembly 200 includes a first side strip 210 and a second side strip 220 arranged opposite to each other. The support assembly 300 includes a first support leg 310, a second support leg 320, a third support leg 330, and a fourth support leg 340.

[0038] The first connecting end of the first side strip 210 is connected to the first side connecting end of the headboard strip 110 and the top of the first support leg 310 via mortise and tenon joints. The last connecting end of the first side strip 210 is connected to the first side connecting end of the footboard strip 120 and the top of the second support leg 320 via mortise and tenon joints. The first connecting end of the second side strip 220 is connected to the second side connecting end of the headboard strip 110 and the top of the third support leg 330 via mortise and tenon joints. The last connecting end of the second side strip 220 is connected to the second side connecting end of the footboard strip 120 and the top of the fourth support leg 340 via mortise and tenon joints. The mortise and tenon joints include a tenon groove, and a reinforcing plate 500 is provided on the surface surrounding the tenon groove.

[0039] like Figure 1-11 As shown in the embodiment of this application, the detachable bed frame is assembled using a mortise and tenon structure. A reinforcing plate 500 is added around the mortise groove. This reinforced mortise and tenon structure design significantly reduces the risk of breakage at the mortise groove. The overall connecting components of the bed frame are simplified, and the detachable connection parts are more stable and secure during use, effectively improving the quality and service life of the bed frame. Furthermore, due to its traditional mortise and tenon structure design, the disassembly and assembly steps are few, making operation convenient and enhancing the practicality of the bed frame.

[0040] Optionally, the upper surfaces of the connecting ends on both sides of the head and tail components 100 are provided with a downwardly recessed first mortise 121, which does not extend to the lower surface, so that the reserved block at the lower part of the first mortise 121 forms a first tenon block 122. The lower surfaces of the connecting ends of the side components 200 are provided with an upwardly recessed second mortise 211, which does not extend to the upper surface, so that the reserved block above the second mortise 211 forms a second tenon block 212. The first mortise 121 matches the second tenon block 212, and the second mortise 211 matches the first tenon block 122. The second tenon block 212 is embedded in the first mortise 121, and the first tenon block 122 is embedded in the second mortise 211, so that the connection between the head and tail components 100 and the side components 200 forms a cross-shaped combination block structure. The reinforcing plate 500 is provided on the outer surfaces of the first mortise 121 and the second mortise 211.

[0041] Adopting the above design, such as Figure 3 , 5 As shown in Figure 6, the mortise and tenon structure design allows the end components 100 and side components 200 to be interlocked. The connection between the end components 100 and the side components 200 forms a cross-shaped assembly block structure, which matches the cross-shaped groove 321 structure of the support component 300 for interlocking. This mortise and tenon structure connects the end components 100 and side components 200 to the support component 300, resulting in a stable and secure connection that is easy to assemble and disassemble. Furthermore, its appearance is aesthetically pleasing and simple, without any additional protrusions, effectively preventing users from being injured by bumps.

[0042] It should be noted that, in this embodiment, the mortise opening of the side component 200 faces upwards, allowing the side component 200 to be moved from top to bottom and inserted into the first and last components 100 to form a cross-shaped assembly. Based on the above design concept, the mortise design at the connection between the side component 200 and the first and last components 100 can also be reversed, allowing the first and last components 100 to be moved from top to bottom and inserted into the side component 200, for example:

[0043] The lower surfaces of the connecting ends on both sides of the head and tail components 100 are provided with upwardly recessed first mortises 121. The first mortises 121 do not extend to the upper surface, so that the reserved block above the first mortises 121 forms a first tenon block 122. The upper surfaces of the connecting ends of the side components 200 are provided with downwardly recessed second mortises 211. The second mortises 211 do not extend to the lower surface, so that the reserved block below the second mortises 211 forms a second tenon block 212. The first mortises 121 and the second tenon block 212 are matched, and the second mortises 211 and the first tenon block 122 are matched. The second tenon block 212 is embedded in the first mortises 121, and the first tenon block 122 is embedded in the second mortises 211, so that the connection between the head and tail components 100 and the side components 200 forms a cross-shaped combination block structure. The reinforcing plates 500 are provided on the outer surfaces of the first mortises 121 and the second mortises 211. Optionally, the top upper surface of the support component 300 is provided with a downwardly recessed cross groove 321; the cross groove 321 matches the cross assembly block structure so that the cross assembly block is fitted into the cross groove 321.

[0044] Similarly, the two ends of the side component 200 or the head and tail component 100 do not need to have the same mortise opening orientation. One can face upwards and the other downwards. According to the above design concept, the connection between the two can match each other to form a cross-shaped combination block structure.

[0045] In addition, in this embodiment, the first tenon 121 and the second tenon 211 are mutually matching square grooves. According to the above design concept, the two can adopt other shapes as long as they can be matched and fitted together, including but not limited to the square grooves in the embodiment.

[0046] Optionally, the head and tail components 100 are provided with a first positioning block 123 near their two connecting ends, and the side component 200 is provided with a second positioning block 213 near its head and tail connecting ends; wherein, when the cross combination block is embedded in the cross groove 321, the first positioning block 123 and the second positioning block 213 respectively abut against the outer peripheral surface of the top of the support component 300.

[0047] like Figure 3 , 5 As shown in Figure 6, with the above design, the first positioning block 123 and the second positioning block 213 can quickly position and insert the connecting ends on both sides of the head and tail components 100 and the head and tail connecting ends of the side components 200 into the cross groove 321, which is convenient for disassembly and assembly and makes the connection more secure and stable.

[0048] Optionally, a relief groove 124 is provided along the periphery of the tenon, the relief groove 124 matching the reinforcing plate 500, so that when the reinforcing plate 500 is fitted into the relief groove 124, the outer surface of the reinforcing plate 500 and the surface of the periphery of the tenon are located on the same plane.

[0049] like Figure 8 , 10 As shown in -11, the design of the relief groove 124 around the first tenon 121 and the second tenon 211 allows the installation of the reinforcing plate 500 to be accommodated, making the mortise and tenon structure easier to assemble and disassemble and convenient to use.

[0050] Optionally, the reinforcing plate 500 is a U-shaped plate structure, which is arranged around the surface surrounding the tenon groove. Optionally, the reinforcing plate 500 is fixedly connected to the surface surrounding the tenon groove by fasteners 510.

[0051] The U-shaped plate structure design of the reinforcing plate 500 allows the reinforcing plate 500 to surround the periphery of the tenon groove and be fastened by the fastener 510, thus firmly installing the reinforcing plate 500 in the relief groove 124 and preventing the reinforcing plate 500 from falling off.

[0052] It should be noted that fastener 510 consists of common bolts, screws, pins, and other similar parts. Fastener 510 achieves its fastening function through its engagement with the screw hole.

[0053] Optionally, it also includes a bed slat 600; the inner side of the side assembly 200 is provided with a support strip 214 protruding into the inner side of the bed frame; the support strip 214 is used to support the bed slat 600.

[0054] Optionally, it also includes a central component 400; the central component 400 includes a central strip 410 and a central support leg 420 for supporting the central strip 410; the two ends of the central strip 410 are detachably and fixedly connected to the central regions of the headboard strip 110 and the footboard strip 120, respectively.

[0055] like Figure 1 As shown, the central component 400 further supports the bed slats 600, improving overall stability. More preferably, the central slat 410 is detachably and fixedly connected to the central support leg 420.

[0056] Optionally, the reinforcing plate 500 is made of metal. It should be noted that the reinforcing plate 500 in this embodiment is made of sheet metal, which provides good reinforcement and fracture resistance.

[0057] Furthermore, those skilled in the art should understand that although many problems exist in the prior art, each embodiment or technical solution of this application can be improved in only one or a few aspects, without necessarily solving all the technical problems listed in the prior art or background art simultaneously. Those skilled in the art should understand that any content not mentioned in a claim should not be construed as a limitation on that claim.

[0058] Although this document frequently uses terms such as head and tail assembly, side assembly, support assembly, middle assembly reinforcing plate, bed slat, headboard slat, footboard slat, first side slat tenon, and tenon, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this application; interpreting them as any kind of additional limitation would contradict the spirit of this application. The terms "first," "second," etc. (if present), in the description of the embodiments of this application, the claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
