[0033] The following description is merely a preferred embodiment of this application and is not intended to limit the scope of this application.

[0034] like Figures 1-6 As shown, a detachable bed frame includes a width support plate 11, a headboard upright plate 1, a footboard horizontal plate 2, two side support frame units 3 that are screwed to the headboard upright plate 1 and the footboard horizontal plate 2 respectively at both ends and have the width support plate 11 on their upper surface, a central screwed frame unit 4 that is disposed between the two side support frame units 3 and is used to support the width support plate 11, and a width connecting frame unit 5 that is screwed to the central screwed frame unit 4 and the two side support frame units 3 and is used together with the width support plate 11 to support the mattress.

[0035] In this embodiment, the structure of the detachable bed frame specifically includes:

[0036] 10 or 12 width-direction support plates 11, 2 headboard uprights 1, 1 footboard crossbar 2, 2 side support frame units 3, 1 central bolted frame unit 4, and 1 width-direction connecting frame unit 5.

[0037] The headboard structure consists of two headboard uprights 1 and one headboard connecting plate 8 screwed together, upon which commonly available upholstered materials and / or backrests are installed to form a complete headboard structure. The width support plate 11, headboard uprights 1, footboard crossbeam 2, side panels 6, and headboard connecting plate 8 are all made of wood; the side support frame unit 3, the central screw-in frame unit 4, and the width connecting frame unit 5 are all made of steel. The footboard crossbeam 2 is generally rectangular in shape, with its long side running horizontally, hence the name "crossbeam," but its sides are perpendicular to the ground, allowing for vertical installation and use.

[0038] Finally, the width-direction support plate 11 is screwed to the side support frame unit 3 and to the middle screw-in frame unit 4; the side support frame unit 3 is screwed to the headboard upright 1, the footboard horizontal plate 2, the side baffle 6, and the width-direction connecting frame unit 5; the middle screw-in frame unit 4 is also screwed to the width-direction connecting frame unit 5. As a result, the detachable bed frame has relatively high stability. Compared with plug-in and hinged connections, the screw connection method has greater structural strength and is relatively less prone to deformation, disintegration, and breakage.

[0039] The side support frame unit 3 includes a length-direction horizontal plate 301, a vertical plate 302 disposed at one end of the length-direction horizontal plate 301 and used to screw the headboard upright 1, a horizontal plate 303 disposed at the other end of the length-direction horizontal plate 301 and used to screw the footboard horizontal plate 2, and a side support plate 304 disposed on the lower surface of the length-direction horizontal plate 301 and screwed to the width-direction connecting frame unit 5.

[0040] In this embodiment, the length-direction horizontal plate 301, vertical plate 302, and horizontal plate 303 are integrally formed into a square tube structure. The side support plate 304 is rectangular in shape, and it can be hollow or not. Its upper end face abuts against the lower surface of the length-direction horizontal plate 301. The connection and fixing effect between the two is provided by the width-direction connecting frame unit 5, that is, the width-direction connecting frame unit 5 simultaneously screws the length-direction horizontal plate 301 and the side support plate 304.

[0041] At this time, the headboard 1 and the footboard 2 respectively function as support legs at the head and foot of the bed, and neither the vertical board 302 nor the horizontal board 303 needs to touch the ground. A side support plate 304 is provided on the longitudinal horizontal board 301, and the side support plate 304 functions as a middle support leg at the long side of the bed frame.

[0042] The central screw-in frame unit 4 includes a length-direction central plate 401 for supporting the width-direction support plate 11 and the width-direction connecting frame unit 5, and a central support plate 402 disposed on the lower surface of the length-direction central plate 401.

[0043] In this embodiment, there are three central support plates 402, corresponding to the central support legs at the head of the bed, the central support legs at the foot of the bed, and the support legs at the center of the entire bed frame.

[0044] Furthermore, the upper end of the middle support plate 402 abuts against the lower surface of the length-to-middle plate 401. The connection between the two is achieved by the subsequent screw connection structure, which is also the meaning of the word "screw connection" in the middle screw connection frame unit 4.

[0045] Correspondingly, the above-mentioned screw-in structure can also position the entire central screw-in frame unit 4, ensuring that:

[0046] 1. The central screw-in frame unit 4 is located in the center between the two side support frame units 3;

[0047] 2. The width-oriented connecting frame unit 5 is located at the center of the middle screw-in frame unit 4;

[0048] 3. The central screw-in frame unit 4 is parallel to the side support frame unit 3 and perpendicular to the width-direction connecting frame unit 5.

[0049] The width-direction connecting frame unit 5 includes a width-direction horizontal plate 501 disposed on the upper surface of the length-direction middle plate 401, and a lower vertical plate 502 disposed at both ends of the width-direction horizontal plate 501 and used to screw the length-direction horizontal plate 301 and the side support plate 304.

[0050] In this embodiment, the width-direction horizontal plate 501 and the two lower vertical plates 502 are integrally formed. The length-direction central plate 401, the central support plate 402, and the width-direction horizontal plate 501 and the lower vertical plates 502 can all be square tube structures. The lower vertical plate 502 can be regarded as a bent section of the aforementioned square tube, which also does not need to touch the ground and may not be connected to the footboard horizontal plate 2.

[0051] On the other hand, the main function of the width-direction horizontal plate 501 is to support the mattress together with the width-direction support plate 11, and the main function of the lower vertical plate 502 is to connect the length-direction horizontal plate 301 and the side support plate 304 at the same time, so that the latter two can be relatively fixed.

[0052] Correspondingly, the length of the width-direction horizontal plate 501 is less than that of the width-direction support plate 11, but this will not significantly affect the support effect on the mattress.

[0053] The central screw-in frame unit 4 also includes an L-shaped connecting piece 403 disposed on the length-direction central plate 401 and the central support plate 402, and connected to the width-direction support plate 11 or the width-direction connecting frame unit 5.

[0054] In this embodiment, one or two L-shaped connecting pieces 403 are provided on a single central support plate 402. When in use, the horizontal section of the L-shaped connecting piece 403 is on top, and it is used to screw the width-direction support plate 11 or the width-direction horizontal plate 501. Its vertical section screws the length-direction central plate 401 and the central support plate 402, thereby fixing the two relatively.

[0055] The L-shaped connecting piece 403 is made of steel and is formed by bending a rectangular steel sheet.

[0056] The side support frame unit 3 further includes a vertical hole 305 disposed on the length transverse plate 301 for mounting the width support plate 11, a transverse hole 306 disposed on the vertical plate 302 and the transverse plate 303 for screwing the headboard upright plate 1 and the footboard transverse plate 2 respectively, and a mounting hole 307 disposed on the length transverse plate 301 and the side support plate 304 for screwing the width connecting frame unit 5.

[0057] In this embodiment, the vertical hole 305 is a threaded hole, and the width of the support plate 11 is installed at the vertical hole 305 by bolts. The width of the support plate 11 can be opened at the aforementioned end position with a circular hole without threads.

[0058] In addition, the transverse hole 306 is a circular hole without threads, and threaded grooves are respectively opened on the headboard 1 and the footboard 2, so that the bolts can be effectively connected without the bolts being exposed.

[0059] Finally, the mounting hole 307 is also a circular hole without threads. The length-direction horizontal plate 301 and the width-direction connecting frame unit 5, as well as the side support plate 304 and the width-direction connecting frame unit 5, are all fixed by a combination of bolts and nuts.

[0060] The detachable bed frame also includes a side baffle 6 disposed on the side of the length transverse plate 301, and the upper surface of which is higher than the width support plate 11; the side support frame unit 3 also includes a connecting hole 308 disposed on the length transverse plate 301 and used to install the side baffle 6.

[0061] In this embodiment, the side baffle 6 is made of wood, and one or two side baffles 6 are provided on a single longitudinal horizontal plate 301.

[0062] The connecting hole 308 is a circular hole without threads, and the inner side of the side baffle 6 is provided with a threaded groove so that the bolt can be effectively connected, and the bolt is not visible on the outer side of the side baffle 6.

[0063] In addition, the bottom edge of the side panel 6 touches the ground and, together with the headboard 1, footboard 2, side support plate 304 and central support plate 402, supports the entire bed frame.

[0064] The central bolted frame unit 4 also includes bolt holes 404 provided on the length-direction central plate 401, central support plate 402 and L-shaped connecting piece 403.

[0065] In this embodiment, the bolt hole 404 refers to an opening for installing bolts, which can be a "bolt hole" even if it is not threaded.

[0066] The bolt holes 404 on the L-shaped connecting piece 403 are unthreaded circular holes, while the bolt holes 404 on the length-oriented middle plate 401 and the middle support plate 402 can be threaded or not.

[0067] Specifically, one bolt hole 404 is provided on the middle plate 401 at a position corresponding to the middle support plate 402, and two bolt holes 404 are provided on the middle support plate 402. Two bolt holes 404 are provided on the upper horizontal section of the L-shaped connecting piece 403, and three bolt holes 404 are provided on its lower vertical section, thus corresponding to a total of three bolt holes 404 on the middle plate 401 and the middle support plate 402.

[0068] The width-direction connecting frame unit 5 also includes a positioning hole 503 disposed on the width-direction horizontal plate 501 for connecting the L-shaped connecting piece 403, and a through hole 504 disposed on the lower vertical plate 502 for connecting the length-direction horizontal plate 301 and the side support plate 304.

[0069] In this embodiment, the positioning hole 503 can be threaded or not. When it is unthreaded, it is a countersunk hole, so that the bolt and nut assembly installed on it will not protrude upwards, otherwise it will damage the mattress.

[0070] Furthermore, the through hole 504 is unthreaded, and a relatively long bolt and nut assembly passes through the through hole 504 and the mounting hole 307, thereby fully connecting the length-oriented horizontal plate 301, the side support plate 304, and the lower vertical plate 502.

[0071] Accordingly, in order to avoid the bolt and nut assembly from affecting the installation of the side baffle 6, the mounting hole 307 can be a countersunk hole, or the inner side of the side baffle 6 can be reserved with a groove to accommodate the bolt and nut assembly. That is, the inner side of the side baffle 6 needs to fit against the length-direction horizontal plate 301 and the side support plate 304, so as to make its installation stable.

[0072] The width-oriented support plate 11 is also provided with a plate opening 7 for connecting the L-shaped connecting piece 403.

[0073] In this embodiment, the use of the opening 7 on the plate is similar to that of the positioning hole 503. It is also possible to have threads on it or not, and it is also necessary to avoid damaging the mattress.

[0074] However, it should be noted that not all of the width-direction support plates 11 need to have the openings 7 on them. Accordingly, since there are three middle support plates 402, one of which is used to connect the width-direction cross plate 501, it is only necessary to have the openings 7 on two of the width-direction support plates 11. These two width-direction support plates 11 must be located at the outermost edge of a row of width-direction support plates 11, that is, one on each side of the headboard and footboard. The remaining width-direction support plates 11 only need to be pressed against the length-direction middle plate 401.

[0075] Finally, the upper surface of the width-direction support plate 11 is flush with the upper surface of the width-direction cross plate 501, thereby providing sufficient support for the mattress. The upper surfaces of the side baffle 6 and the footboard cross plate 2 are higher than the aforementioned flush surfaces, thus making it less likely for the mattress to shift or slip off the bed frame.

[0076] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of this application. These are non-inventive modifications and are protected by patent law as long as they are within the scope of the claims of this application.
