Specific embodiments

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present invention. The same or similar reference numerals in the drawings represent the same or similar components.

[0025] Refer to Figures 1 to 4 , an embodiment of a bed frame structure provided by the present invention includes a frame body 1 with a rectangular outer contour, a plurality of support feet 3 vertically connected to the frame body 1, and a plurality of support rods 8 spaced apart on the frame body 1. A plurality of mounting holes 5 are spaced apart on two opposite inner sides of the frame body 1, and an elastic positioning part 7 is movably fitted in the mounting holes 5.

[0026] Refer to Figure 5 , Figure 6 , a positioning groove 9 is provided on one side of the positioning part 7 facing the inside of the frame body 1, and the groove width of the positioning groove 9 is adapted to the rod width of the support rod 8, so as to accommodate the support rod 8. A second retaining edge 19a is provided on the opening side of the positioning groove 9 and a first retaining edge 19b is provided on the upper side. After the positioning part 7 is manually pushed into the mounting hole 5, the second retaining edge 19a and the first retaining edge 19b abut against the tube wall of the frame body 1, thereby limiting the positioning part 7. And a plurality of support rods 8 are installed in the positioning groove 9 of the positioning part 7.

[0027] Assembly process: First, insert the positioning part 7 into the mounting hole 5. The elastic (such as plastic, rubber) positioning part 7 is first squeezed by the tube wall of the frame body 1, and then the second retaining edge 19a and the first retaining edge 19b abut against the tube wall of the frame body 1 to realize the limitation of the positioning part 7 on the frame body 1. Then, put the end of the support rod 8 into the space of the positioning groove 9 of the positioning part 7 to complete the limitation of the support rod 8 on the frame body 1.

[0028] It can be seen that by removing some materials from the frame 1 to create the mounting holes 5 and using the elastic positioning member 7 to replace the traditional metal U-shaped block, the weight of the bed frame is significantly reduced. Moreover, the positioning member 7 is elastic, and the positioning member 7 can be manually pushed into the mounting hole 5. Therefore, this structure not only has the characteristics of simple assembly, but also reduces the manufacturing cost and transportation cost.

[0029] Continue to refer to Figure 5 、 Figure 6 For further strengthening the positioning of the positioning member 7 on the frame 1 and preventing the positioning member 7 from shaking, guiding protrusions are provided on the outer walls of both sides of the positioning groove 9. In this embodiment, the pipe body forming the frame 1 is a square pipe with a hollow structure. A transverse groove 20a is provided between the guiding protrusion and the second retaining edge 19a, and a longitudinal groove 20b is provided between the guiding protrusion and the first retaining edge 19b. When the positioning member 7 is pushed into the mounting hole 5, the guiding protrusion first abuts against the wall body of the frame 1, and then enters the inner cavity of the pipe body, and the pipe wall is clamped with the transverse groove 20a and the transverse groove 20a to further limit the positioning member 7.

[0030] Continue to refer to Figure 5 、 Figure 6 The guiding protrusion is a slope that gradually rises from the back surface of the positioning groove 9 towards the opening side. In this way, a guiding effect can be provided throughout the process of the positioning member 7 entering the mounting hole 5, which is more convenient and improves the user experience.

[0031] Refer to Figure 3 On the upper surface of the mounting hole 5, a through hole adapted to the end face shape of the guiding protrusion is provided. When it is necessary to remove the positioning member 7 from the frame 1, two fingers squeeze the two second retaining edges 19a of the positioning member 7 towards each other, slide the positioning member 7 upwards along the transverse groove 20a, and then pass through the through hole, so as to achieve rapid removal.

[0032] Specifically, refer to Figure 1 、 Figure 2 And Figure 4 The frame 1 includes two outer horizontal bars 1a and two outer vertical bars 1b that can be detachably connected to each other. The outer horizontal bar 1a is perpendicularly connected to the outer vertical bar 1b, such as by screw connection or snap connection. The above-mentioned mounting holes 5 are provided on the two outer vertical bars 1b. In this way, the product is in a disassembled state during transportation, reducing the packaging size, facilitating transportation and also reducing the transportation cost.

[0033] For a large-sized bed frame, to improve its stability, the frame 1 further includes an intermediate vertical bar 2 and an intermediate horizontal bar 10 that makes the intermediate vertical bar 2 more stable. Among them, the intermediate vertical bar 2 is perpendicularly connected to the intermediate horizontal bar 10, both ends of the intermediate vertical bar 2 are connected to the outer horizontal bar 1a, and both ends of the intermediate horizontal bar 10 are connected to the outer vertical bar 1b.

[0034] In some embodiments, the support rod 8 is an integral long rod, and the support rod 8 spans across the middle longitudinal rod 2, and the middle longitudinal rod 2 is mainly used to support the support rod 8. In this embodiment, the support rod 8 is a segmented type, that is, a short rod. A plurality of U-shaped members corresponding to the positioning members 7 are provided at intervals on both sides of the middle longitudinal rod 2. The fixing method of the U-shaped members on the middle longitudinal rod 2 can be inlaying, welding, or threaded connection, and the material thereof can be hard plastic, light metal, etc. In this embodiment, to avoid insufficient strength caused by the method of digging holes in all longitudinal rods, the fixing method of the U-shaped members on the middle longitudinal rod 2 is welding on both sides. One end of the support rod 8 is placed in the positioning groove 9, and the other end is placed in the U-shaped member. In this way, both the overall strength of the bed frame is ensured, and at the same time, rapid assembly and reduction of the packaging length are achieved.

[0035] Specifically, referring to Figure 1 , the outer horizontal bar 1a, the outer longitudinal bar 1b, the middle longitudinal bar 2, and the middle horizontal bar 10 in this embodiment are all foldable structures. In this way, their lengths can be further reduced, making transportation more convenient.

[0036] Referring to Figure 2 , the outer horizontal bar 1a and the outer longitudinal bar 1b both include two first short bars 13. One end of the two first short bars 13 opposite to each other is hinged to the upper end of the support foot 3 and unfolds into a T shape. The other end of the first short bar 13 of the outer horizontal bar 1a or the outer longitudinal bar 1b is hinged with the support foot 3. The middle longitudinal bar 2 includes two second short bars 12. One end of the two second short bars 12 opposite to each other is hinged to the upper end of the support foot 3 and unfolds into a T shape, and the other end is connected to the outer horizontal bar 1a. The middle horizontal bar 10 includes two third short bars 11. One end of the two third short bars 11 opposite to each other is connected to the middle longitudinal bar 2, and the other end is connected to the outer longitudinal bar 1b. Among them, the above-mentioned rod bodies are threadedly connected through a plurality of connecting pieces 15 and connecting screws 16 provided with connecting holes 14. During transportation, the above structure is in a folded state. During assembly, it is correspondingly unfolded, and the connecting pieces 15 and connecting screws 16 are used to achieve fixed connection. It is not only convenient for transportation, and each part is initially in a hinged state, so the risk of part loss is small. At the same time, in this step of assembly, the rectangular frame 1 and the support foot 3 can be assembled synchronously, the assembly workload is smaller, and the overall structure of the assembled bed frame is stronger, further improving the stability.

[0037] Referring to Figure 4 and Figure 7 , the frame 1 further includes a plurality of retaining pieces 17 oppositely arranged on the rectangular frame 1. The top end of the retaining piece 17 is higher than the frame 1, which can quickly position the mattress and prevent it from shifting.

[0038] Continuing to refer to Figure 7, the longitudinal section of the baffle 17 is L-shaped. By quickly fitting the baffle 17 with the side and bottom of the frame 1 and then using threaded connection or welding to fix it to the frame 1. In this way, it is difficult for the baffle 17 to shift laterally, and the position of the baffle 17 can be kept stable, enabling it to perform the function of positioning the mattress.

[0039] Refer again to Figure 1 , a plurality of mounting holes 5 are provided on the support feet 3 located at the head and / or foot of the bed, for mounting a headboard or a footboard (not shown in the figure), so that the user can independently choose the styles of the headboard and the footboard they like, improving the usage experience.
