[0001] This utility model relates to the field of furniture technology, and in particular to a quick-assembly folding bed frame and bed. Background Technology

[0002] Existing folding bed frames, such as the patent document with authorization announcement number CN217524418U, disclose a bed frame folding support device, including: an upper support member, the upper end of which is provided with a hinge structure for mounting on the folding part of the upper bed frame; a movable support member, which is movably mounted on the upper support member in the height direction of the bed frame and can contact the ground when it is in the extended position to cooperate with the ground support frame of the bed frame to support the bed frame, wherein the movable support member is hinged with a bracket that can move with the movable support member, the bracket including a first diagonal tie rod for hinged to a first side upper bed frame of the upper bed frame and a second diagonal tie rod for hinged to a second side upper bed frame of the upper bed frame.

[0003] While the aforementioned bed frames can be folded and unfolded in one operation, offering high efficiency in disassembly and use, they still possess considerable width and volume when folded, resulting in high transportation costs. Therefore, existing bed frames fail to achieve an effective balance between efficiency in disassembly and use and transportation costs. Utility Model Content

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1 As shown in the figure, this specification provides a quick-assembly folding bed frame, including a main frame 1, a secondary frame 2 and support legs 3. A secondary frame 2 is provided at each of the opposite ends of the main frame 1, that is, the support surface of the entire bed frame is formed by one main frame 1 and two secondary frame 2. Support legs 3 are installed under the main frame 1 and the secondary frame 2 to form a complete bed frame.

[0019] The main frame 1 includes a main connecting seat 11, main longitudinal members 12, and main width members 13. The two main longitudinal members 12 are rotatably connected to opposite ends of the main connecting seat 11, and the two main width members 13 are rotatably connected to opposite ends of the main connecting seat 11. Thus, when the main frame 1 is unfolded, it forms a cross-shaped support structure with a large support range. When the main frame 1 is folded, the two main longitudinal members 12 and the two main width members 13 can rotate upwards and converge, forming a cross-shaped support structure. Figure 5 As shown, its width and volume are relatively small, making it easy to transport and store.

[0020] like Figure 2As shown, the main connecting seat 11 includes a main base plate 111 and main groove-shaped components 112. The main base plate 111 is cross-shaped, with a main groove-shaped component 112 at each of its four ends. The main groove-shaped components 112 are U-shaped, and the four main groove-shaped components 112 are rotatably connected to two main longitudinal rods 12 and two main lateral rods 13 via shafts. In this way, the main longitudinal rods 12 and the main lateral rods 13 can only rotate upwards, while downward rotation is restricted, so as to ensure the levelness of the support surface and the structural stability when the main frame 1 is in the unfolded state. In addition, since a support foot 3 needs to be installed below the main base plate 111, a first operating space is left between the four main groove-shaped components 112 for easy disassembly and assembly. The main base plate 111 has a first support foot mounting hole 1111 below the first operating space. Correspondingly, each support foot 3 has a threaded hole 31 at its upper end to facilitate the installation of the support foot 3 by bolting from above the main base plate 111.

[0021] To further improve the structural stability of the main frame 1 in its unfolded state, reinforcement members 4 are installed between the two main longitudinal members 12 and the two main transverse members 13. For example... Figure 3 As shown, the reinforcement 4 specifically includes a main body 41 and a slot 42. The main body 41 is cross-shaped, with downward-facing slots 42 at each of its four ends. The four slots 42 are used to engage with two main longitudinal rods 12 and two main width rods 13, respectively. Each slot 42 has a fixing hole 421 between itself and the corresponding main longitudinal rod 12 or main width rod 13. In use, with the main frame 1 in a horizontally unfolded state and support feet 3 installed below the main base plate 111, the reinforcement 4 is fastened from top to bottom onto the two main longitudinal rods 12 and two main width rods 13. Then, bolts are used to connect and fix the reinforcement 4 to the four rods through the fixing holes 421.

[0022] like Figure 4 As shown, the sub-frame 2 includes a sub-connecting seat 21 and two sub-longitudinal rods 22. The two sub-longitudinal rods 22 are respectively rotatably connected to opposite ends of the sub-connecting seat 21. Thus, when the sub-frame 2 is unfolded, it forms a straight structure; when folded, the two sub-longitudinal rods 22 rotate to the same side and move closer together, forming a shape like... Figure 6As shown, this configuration occupies less space, facilitating transportation and storage. Correspondingly, the secondary connector 21 includes a secondary base plate 211 and secondary slotted components 212. The secondary base plate 211 has three secondary slotted components 212, each U-shaped. These components can be installed independently on the secondary base plate 211 or formed by bending a portion of the secondary base plate 211. The three secondary slotted components 212 are rotatably connected to two secondary longitudinal rods 22 and fixedly connected to one main width rod 13. When the main width rod 13 is inserted into the secondary slotted component 212 from top to bottom, the two can be connected and fixed using bolts. A second operating space is provided between the three secondary slotted components 212. A second support foot mounting hole is provided on the secondary base plate 211 below the second operating space, allowing support feet 3 to be installed from above the secondary base plate 211 via bolts. In addition, in order to improve the structural strength of the secondary connecting seat 21, two secondary slotted parts 212 that are rotatably connected to the two secondary longitudinal rods 22 are integrally connected to the side wall away from the main frame 1. Since no connecting rod is needed on this side, it can be closed to improve the structural strength.

[0023] As needed, a corresponding number of support feet 3 can be installed under the main frame 1 and the sub-frame 2. Generally, a support foot needs to be set under the main connecting seat 11, the sub-connecting seat 21 and the end of each rod. If it can be fixed in conjunction with the outer frame of the bed, some of the support feet can be omitted.

[0024] like Figure 7 As shown in the embodiment of this specification, a bed is also provided, including a frame 5 and a quick-assembly folding bed frame as described above. The frame 5 is composed of multiple side panels connected in sequence, and the quick-assembly folding bed frame is disposed inside the frame 5. In order to make the folding bed frame and the frame 5 fit more tightly and reduce shaking during use, support members 51 are provided at the four corners inside the frame 5. The support members are connected to the frame 5 by bolts and have a horizontal support surface. The four secondary longitudinal rods 22 are respectively connected to the four support members 51 by bolts. In this way, the support feet 3 below the secondary longitudinal rods 22 can be omitted.

[0025] The above are merely preferred embodiments of this utility model, and are implementations based on the overall concept of this utility model. Furthermore, the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
