[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0046] The directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "inner," "outer," and "side," are merely for reference to the accompanying drawings. Therefore, the directional terms used are for explanation and understanding of this invention, and not for limiting it. Furthermore, in the accompanying drawings, structures that are similar or identical are indicated by the same reference numerals.

[0047] Reference Figures 1 to 8 This utility model provides a detachable bed frame. The structure and working principle of this detachable bed frame will be described in detail below with reference to the accompanying drawings. Figures 1 to 8As shown, the detachable bed frame includes: a detachable bed body 10, which includes an upper frame 1, a lower frame 2, support columns 3, and a support keel 4. The upper frame 1 and the lower frame 2 are spaced apart vertically and connected by the support columns 3. The support keel 4 is connected to the upper frame 1. Both the upper frame 1 and the lower frame 2 include two parallel horizontal bars 11 and two parallel vertical bars 12, which are perpendicular to each other. The upper and lower ends of the support columns 3 are provided with mutually perpendicularly extending transverse connecting parts 31 and longitudinal connecting parts 32. The transverse connecting parts 31 and the longitudinal connecting parts 32 are detachably connected to the ends of the horizontal bars 11 and the vertical bars 12, respectively. The support keel 4 is detachably connected to the two horizontal bars 11 or the two vertical bars 12 of the upper frame 1. A ribbed bed board 20 is laid on the upper frame 1 and the support keel 4 and can be folded for storage.

[0048] In practical implementation, the detachable bed frame mainly includes a detachable bed body 10 and a slatted bed board 20. The detachable bed body 10 is the main part of the detachable bed frame, mainly designed with metal materials. The detachable bed body 10 serves as the main structure of the detachable bed frame and can be completely disassembled. The slatted bed board 20 is a foldable and storable slatted structure, set on the upper side of the detachable bed body 10 as a support structure. Specifically, the detachable bed body 10 includes an upper frame 1, a lower frame 2, support columns 3, and support ribs 4. The upper frame 1 and lower frame 2 are both rectangular frame structures, and are arranged vertically and horizontally, with the upper frame 1 on top, mainly used to support the human body, while the lower frame 2 is on the bottom, mainly used for ground support. The upper frame 1 and lower frame 2 are connected by the support columns 3, specifically, the upper end of the support column 3 connects to the upper frame 1, and the lower end connects to the lower frame 2. In practical applications, the number of support columns 3 can be set to four, respectively connected to the four corners of the upper frame 1 and the lower frame 2. After the lower frame 2 touches the ground, the upper frame 1 is supported by the support columns 3 at a certain height above the ground. The number of support keels 4 can be at least one. The support keel 4 is mainly connected to the upper frame 1, and its main purpose is to touch the ground and provide support, so as to strengthen the overall support capacity of the frame structure and improve its stability.

[0049] Specifically, such as Figures 5 to 7As shown, both the upper frame 1 and the lower frame 2 consist of two parallel horizontal bars 11 and two parallel vertical bars 12. The horizontal bars 11 are arranged transversely, and the vertical bars 12 are arranged longitudinally, perpendicular to each other. According to the design requirements of the bed frame size, the length of the horizontal bars 11 is usually less than the length of the vertical bars 12. The horizontal bars 11 of the upper frame 1 are the same length as those of the lower frame 2, and the vertical bars 12 of the upper frame 1 are the same length as those of the lower frame 2. The bed frame size can usually be set to 1.8m×1.5m, 1.8m×1.2m, etc. The specific lengths of the horizontal bars 11 and vertical bars 12 can be designed according to the size requirements of the bed frame. The upper and lower ends of the support column 3 are provided with transverse connecting parts 31 and longitudinal connecting parts 32 extending perpendicularly to each other. The transverse connecting parts 31 and longitudinal connecting parts 32 are detachably connected to the ends of the horizontal bars 11 and vertical bars 12, respectively. Specifically, the transverse connecting part 31 and the longitudinal connecting part 32 extend perpendicularly to each other. The transverse connecting part 31 extends in the axial direction of the crossbar 11, and the longitudinal connecting part 32 extends in the axial direction of the longitudinal bar 12. The transverse connecting part 31 at the upper end of the support column 3 is detachably connected to the crossbar 11 of the upper frame 1, and the longitudinal connecting part 32 at the upper end of the support column 3 is detachably connected to the longitudinal bar 12 of the upper frame 1. The transverse connecting part 31 at the lower end of the support column 3 is detachably connected to the crossbar 11 of the lower frame 2, and the longitudinal connecting part 32 at the lower end of the support column 3 is detachably connected to the longitudinal bar 12 of the lower frame 2. The supporting keel 4 is entirely housed within the upper frame 1. The supporting keel 4 is detachably connected to either the two horizontal bars 11 or the two vertical bars 12 of the upper frame 1. Specifically, the supporting keel 4 can be configured in two ways: horizontally or vertically. If the supporting keel 4 is horizontally configured, it remains parallel to the horizontal bars 11 and is detachably connected to the two vertical bars 12 of the upper frame 1. If the supporting keel 4 is vertically configured, it remains parallel to the vertical bars 12 and is detachably connected to the two horizontal bars 11 of the upper frame 1. The slatted bed board 20 is laid on top of the upper frame 1 and the supporting keel 4, and the slatted bed board 20 can be folded for storage.

[0050] In practical applications, when the detachable bed frame is assembled, the horizontal bars 11 and vertical bars 12 of the lower frame 2 form a square lower frame 2 structure, which provides stable ground support and prevents the bed from shaking. The horizontal bars 11 and vertical bars 12 of the upper frame 1 form a square upper frame 1 structure. The upper frame 1 is connected to the supporting keel 4 to form a stable supporting skeleton. The ribbed bed board 20 is laid on the upper frame 1 and the supporting keel 4, thereby providing even and stable support for the mattress or the human body. When the detachable bed frame needs to be transported or stored, it can be disassembled and packed as a whole. Specifically, first remove and fold the slatted bed board 20, then remove the supporting keel 4 from the horizontal bar 11 or vertical bar 12 of the upper frame 1. Next, remove the two horizontal bars 11 and two vertical bars 12 of the upper frame 1 from the transverse connection part 31 and the longitudinal connection part 32 at the upper end of the support column 3. Then, remove the two horizontal bars 11 and two vertical bars 12 of the lower frame 2 from the transverse connection part 31 and the longitudinal connection part 32 at the lower end of the support column 3, thereby completely disassembling the bed frame. Figure 8 As shown, the disassembled crossbars 11, longitudinal bars 12, support columns 3, support keels 4, and longitudinal bars 12 are neatly stacked together and packaged, which greatly reduces the packaging volume during transportation of the detachable bed frame. It can easily adapt to various spatial environments, and will not take up much space when stored when not in use. It is also very convenient to assemble.

[0051] In a further embodiment, refer to Figure 2 , Figure 3 , Figure 4 as well as Figure 9 The detachable bed frame 10 also includes a limiting member 5. One end of the limiting member 5 is detachably connected to the crossbar 11 of the lower frame 2 and is a certain distance from its end. The other end of the limiting member 5 is detachably connected to the longitudinal bar 12 of the lower frame 2 and is a certain distance from its end. The limiting member 5 is used to restrict the axial movement of the crossbar 11 toward the longitudinal bar 12 and the axial movement of the longitudinal bar 12 toward the crossbar 11. In a specific implementation, the detachable bed frame 10 also includes four limiting members 5, which are respectively connected to the four corners of the lower frame 2 to enhance the stability of the lower frame 2. Specifically, one end of the limiting member 5 is detachably connected to the crossbar 11 of the lower frame 2 and is a certain distance away from the end of the crossbar 11 of the lower frame 2. The other end of the limiting member 5 is detachably connected to the longitudinal bar 12 of the lower frame 2 and is a certain distance away from the end of the longitudinal bar 12 of the lower frame 2. Thus, the limiting member 5 forms a triangular structure with the crossbar 11 and the longitudinal bar 12 of the lower frame 2, which can restrict the relative movement between the crossbar 11 and the longitudinal bar 12, improve the structural stability of the lower frame 2, and the detachable connection between the limiting member 5 and the crossbar 11 and the longitudinal bar 12 of the lower frame 2 makes assembly or disassembly very convenient.

[0052] In a further embodiment, refer to Figure 10 The limiting member 5 has a first groove 51 matching the shape of the crossbar 11 and a second groove 52 matching the shape of the vertical bar 12 at both ends. The crossbar 11 of the lower frame 2 is embedded in the first groove 51, and the vertical bar 12 of the lower frame 2 is embedded in the second groove 52. In a specific implementation, the limiting member 5 has a first groove 51 and a second groove 52 at both ends. The first groove 51 and the second groove 52 extend in two mutually perpendicular directions. Both the first groove 51 and the second groove 52 are U-shaped groove structures. The first groove 51 matches the shape of the crossbar 11 of the lower frame 2, and the second groove 52 matches the shape of the vertical bar 12 of the lower frame 2. In the assembled state, the crossbar 11 of the lower frame 2 is detachably embedded in the first groove 51, and the longitudinal bar 12 of the lower frame 2 is detachably embedded in the second groove 52. This can restrict the movement of the crossbar 11 and the longitudinal bar 12 relative to each other, thereby stabilizing the lower frame 2 and preventing the bed from swaying left and right. Moreover, the assembly and disassembly of the limiting member 5 are very simple and convenient.

[0053] In one embodiment, reference is made to Figure 11 The upper and lower ends of the support column 3 have grooves 301 formed in the transverse connecting portion 31 and the longitudinal connecting portion 32. The ends of the crossbar 11 and the longitudinal bar 12 are embedded in the grooves 301. In a specific implementation, grooves 301 are formed in the transverse connecting portion 31 and the longitudinal connecting portion 32 at the upper and lower ends of the support column 3. The grooves 301 on the transverse connecting portion 31 and the longitudinal connecting portion 32 are U-shaped groove structures. The grooves 301 on the transverse connecting portion 31 and the longitudinal connecting portion 32 at the upper end of the support column 3 match the shape of the crossbar 11 and the longitudinal bar 12 of the upper frame 1. The grooves 301 on the transverse connecting portion 31 and the longitudinal connecting portion 32 at the lower end of the support column 3 match the shape of the crossbar 11 and the longitudinal bar 12 of the lower frame 2. The slots 301 on the transverse connecting part 31 and the longitudinal connecting part 32 at the upper end of the support column 3 are designed with the slot openings facing upwards, while the slots 301 on the transverse connecting part 31 and the longitudinal connecting part 32 at the lower end of the support column 3 are designed with the slot openings facing downwards, facilitating installation. In the assembled state, the ends of the horizontal bars 11 and the vertical bars 12 of the upper frame 1 are detachably embedded into the slots 301 of the transverse connecting part 31 and the longitudinal connecting part 32 at the upper end of the support column 3, respectively. The ends of the horizontal bars 11 and the vertical bars 12 of the lower frame 2 are also detachably embedded into the slots 301 of the transverse connecting part 31 and the longitudinal connecting part 32 at the lower end of the support column 3, respectively, achieving a detachable connection between the horizontal bars 11 and the vertical bars 12 and the support column 3. The assembly and disassembly of the horizontal bars 11 and the vertical bars 12 and the support column 3 are very simple and convenient.

[0054] In a further embodiment, refer to Figures 11 to 13The detachable bed frame 10 also includes a hand-tightening screw 7. Both the transverse connecting part 31 and the longitudinal connecting part 32 are provided with through holes 302 extending into the slot 301. The ends of the crossbar 11 and the longitudinal bar 12 are each provided with a first threaded hole 101. The hand-tightening screw 7 passes through the through hole 302 and is threadedly connected to the first threaded hole 101. In a specific implementation, through holes 302 extending into the slot 301 are provided on both the transverse connecting part 31 and the longitudinal connecting part 32, and first threaded holes 101 are provided at corresponding positions at the ends of the crossbar 11 and the longitudinal bar 12. The detachable bed frame 10 also includes hand-tightening screws 7, the number of which corresponds to the number of through holes 302. The hand-tightening screw 7 is a fastener that can be manually tightened or loosened without tools, and its knurled head design enhances grip. In the assembled state, the hand-tightening screw 7 passes through the through hole 302 on the transverse connecting part 31 and is threaded into the first screw hole 101 at the end of the crossbar 11. Similarly, the hand-tightening screw 7 passes through the through hole 302 on the longitudinal connecting part 32 and is threaded into the first screw hole 101 at the end of the longitudinal bar 12. During actual bed installation, the user can manually tighten the hand-tightening screw 7 without tools to fix the ends of the crossbars 11 and longitudinal bars 12 of the upper frame 1 and lower frame 2 into the slots 301 at both ends of the support column 3, making the bed structure more stable. When disassembling the bed, the user can easily remove the ends of the crossbars 11 and longitudinal bars 12 of the upper frame 1 and lower frame 2 from both ends of the support column 3 without tools, by manually unscrewing the hand-tightening screw 7 out of the first screw hole 101.

[0055] In one embodiment, reference is made to Figures 2 to 4 The detachable bed frame 10 also includes several side support rods 6. A portion of the side support rods 6 are detachably connected between the crossbar 11 of the upper frame 1 and the crossbar 11 of the lower frame 2, and another portion of the side support rods 6 are detachably connected between the longitudinal rod 12 of the upper frame 1 and the longitudinal rod 12 of the lower frame 2. In specific implementation, the detachable bed frame 10 also includes several side support rods 6. The number of side support rods 6 is unlimited. All side support rods 6 are arranged vertically. In the assembled state, some of the side support rods 6 are detachably connected between the crossbars 11 of the upper frame 1 and the crossbars 11 of the lower frame 2, and other side support rods 6 are detachably connected between the longitudinal rods 12 of the upper frame 1 and the longitudinal rods 12 of the lower frame 2. The side support rods 6 can enhance the stability of the connection between the crossbars 11 and longitudinal rods 12 of the upper frame 1 and the crossbars 11 and longitudinal rods 12 of the lower frame 2, making the overall frame structure more stable. Moreover, the side support rods 6 can be flexibly disassembled relative to the crossbars 11 and longitudinal rods 12 of the upper frame 1 and the lower frame 2, making the bed frame disassembly more convenient.

[0056] In a further embodiment, refer to Figure 14 and Figure 15 The upper frame 1 has second screw holes 102 at the bottom of both the crossbar 11 and the vertical bar 12, and the lower frame 2 has insertion holes 103 at the top of both the crossbar 11 and the vertical bar 12. The upper end of the side support rod 6 is threaded to the second screw hole 102, and the lower end of the side support rod 6 is inserted into the insertion hole 103. Specifically, the lower end of the side support rod 6 is a stud structure with a thread matching the second screw hole 102, and is threaded to the second screw hole 102. The other end of the side support rod 6 is directly inserted into the insertion hole 103, and is removable from the insertion hole 103. In practical applications, when assembling the bed frame, one end of the side support rod 6 can be screwed into the second screw hole 102 at the bottom of the crossbar 11 and longitudinal bar 12 of the upper frame 1 and tightened. Then, the other end of the side support rod 6 can be inserted into the insertion hole 103 of the crossbar 11 and longitudinal bar 12 of the lower frame 2, which can easily complete the installation of the side support rod 6. When disassembling the bed frame, one end of the side support rod 6 is pulled out of the insertion hole 103, and then the side support rod 6 is rotated to unscrew the other end out of the second screw hole 102, which can remove the side support rod 6. The assembly and disassembly of the side support rod 6 are very convenient.

[0057] In one embodiment, reference is made to Figure 16 The supporting keel 4 includes a beam 41 and a support column 42. The beam 41 is located between the two crossbars 11 of the upper frame 1, and its two ends are detachably connected to the two crossbars 11 respectively. The support column 42 is vertically located below the beam 41, and its top end is detachably connected to the beam 41. The bottom end of the support column 42 is flush with the bottom of the lower frame 2. In specific implementation, the supporting keel 4 includes a beam 41 and a support column 42. The beam 41 is a rod-shaped structure with the same length as the longitudinal bar 12. The direction of the beam 41 is the same as that of the longitudinal bar 12, both being longitudinally arranged. The beam 41 is located between the two beams 41 of the upper frame 1, parallel to the longitudinal bar 12, and its two ends are detachably connected to the two crossbars 11 of the upper frame 1 respectively. The support column 42 is vertically located below the beam 41, and its top end is detachably connected to the bottom of the beam 41. The bottom end of the support column 42 is flush with the bottom of the lower frame 2. In practical applications, the bottom of the support column 42 touches the ground, supporting the bone beam 41.

In specific implementation, each of the two crossbars 11 of the upper frame 1 has an upward-facing slot 1101 on one side facing each other, the number of slots 1101 on the two crossbars 11 is the same and their positions correspond, and the number of slots 1101 on the two crossbars 11 is set according to the number of supporting ribs 4. All slots 1101 are open facing upwards, with the openings facing upwards. The ends of the supporting beams 41 of the keel 4 are detachably embedded in the slots 1101. That is, one end of the beam 41 is detachably embedded in the slot 1101 of the crossbar 11 of the upper frame 1, and the other end of the crossbar 11 is detachably embedded in the slot 1101 of the other crossbar 11 of the upper frame 1. The slots 1101 provide a connection for the supporting beams 41 of the keel 4. The beams 41 can be flexibly assembled and disassembled, which is very convenient.

[0059] In one embodiment, reference is made to Figure 19 The slatted bed board 20 includes several parallel panels 21 arranged at intervals along the same direction. The panels 21 are placed flat on the upper frame 1 and the bone beams 41 and are perpendicular to the bone beams 41. All the panels 21 are connected by flexible webbing 22, and adjacent panels 21 can be folded together. In specific implementation, the slatted bed board 20 includes several panels 21, which are flat, plate-like structures. The number of panels 21 is determined by the size of the bed; the larger the bed, the more panels 21 are required. All panels 21 are arranged parallel at intervals along the same direction, with a distance of one panel 21 width between each adjacent panel 21. Each panel 21 is placed flat on the upper frame 1 and the bone beams 41 and is perpendicular to the bone beams 41. All panels 21 are supported by the upper frame 1 and the bone beams 41, and their ends do not extend beyond the two longitudinal bars 12 of the upper frame 1. All the panels 21 are connected by flexible webbing 22, which can be made of high-toughness nylon material. Due to the flexibility of the webbing 22, adjacent panels 21 can be folded together, so that all the panels 21 can be stacked together to form a roll, which does not take up much space when stored.

[0060] In a further embodiment, refer to Figure 18 and Figure 20Each of the two longitudinal bars 12 of the upper frame 1 has an inner flange 121 protruding from its opposing sides, and the end of each shelf 21 rests flat on the inner flange 121. In specific implementation, each of the two longitudinal bars 12 of the upper frame 1 has an inner flange 121 protruding from its opposing sides. Specifically, the inner flange 121 of one longitudinal bar 12 of the upper frame 1 protrudes toward the other longitudinal bar 12, and the inner flange 121 extends axially in the longitudinal bar 12. The end of each shelf 21 rests flat on the inner flange 121, which provides support for the end of the shelf 21, preventing the shelf 21 from warping and making the overall support of the bone bed board 20 more stable.

[0061] In one embodiment, reference is made to Figure 16 , Figure 21 as well as Figure 22 The bone beam 41 has two sets of limiting blocks 4101 protruding upwards. One set of limiting blocks 4101 is embedded between the first two adjacent rows of plates 21, and the other set of limiting blocks 4101 is embedded between the last two adjacent rows of plates 21. In a specific implementation, the bone beam 41 has two sets of limiting blocks 4101 protruding upwards. The two sets of limiting blocks 4101 are respectively located near both ends of the bone beam 41 and are far apart from each other. Each set of limiting blocks 4101 may include two limiting blocks 4101. The bone bed board 20 is composed of several parallel and spaced boards 21 connected by webbing 22. The axial length of the limiting block 4101 is less than the interval between two adjacent boards 21. One set of limiting blocks 4101 on the bone beam 41 is embedded between the first two adjacent boards 21, and the other set of limiting blocks 4101 is embedded between the last two adjacent boards 21. Thus, the two ends of the bone bed board 20 are positioned by the two sets of limiting blocks 4101, so that the bone bed board 20 can be kept flat and the boards 21 of the bone bed board 20 can be prevented from stacking together when the bed is in use.

[0062] In summary, the detachable bed frame provided in this application embodiment can be completely disassembled for packaging, greatly reducing packaging volume, facilitating transportation, easily adapting to various spatial environments, and can be assembled and disassembled without the need for tools, which is very convenient.

The size of the backrest cushion 220 is designed according to the width of the detachable bed frame 100, and the size of the mattress 210 is precisely designed according to the length and width of the detachable bed frame 100. Both the backrest cushion 220 and the mattress 210 can be elastically compressed. During the compression process, the elasticity and support of the mattress 210 remain unchanged. The volume can be greatly reduced by rolling and pressing, and it can return to its natural shape after unfolding. The backrest cushion 220 and mattress 210 are independently assembled onto the detachable bed frame 100. The backrest cushion 220 is attached to the headboard side of the detachable bed frame 100, typically installed against the wall. The backrest cushion 220 provides back support and also serves a decorative purpose. The mattress 210 is attached to the upper side of the detachable bed frame 100, supported by the upper frame 1 and the slatted bed board 20. The mattress 210 primarily provides support, protects spinal health, and improves rest comfort. In practical applications, the backrest cushion 220, mattress 210, and detachable bed frame 100 are used together. When the bed 200 is shipped from the factory or needs to be stored, such as... Figure 24 As shown, the detachable bed frame 100 can be completely disassembled and packed away. The backrest cushion 220 and mattress 210 can be flattened, rolled up, and then packed.
