Description

Technical Field

[0001] The utility model relates to the field of furniture, in particular to a combined bed frame. Background Art

[0002] A bed is a piece of furniture placed in the bedroom for people to lie down. Generally speaking, a bed is large in size, heavy in overall weight, and occupies a large area. Therefore, the beds currently on the market are usually configured to be composed of wooden boards and / or iron frames and connecting parts. During transportation and handling, the various parts of the bed are transported and handled separately to save logistics space and facilitate handling. Finally, after the various parts of the bed are transported to the bedroom, they are assembled on site by the installers.

[0003] The patent application with publication number CN217234036U discloses a snap-on connection structure and a bed frame thereof. When assembling, the second card arranged at one end of the second connecting member is inserted into the limiting groove of the first connecting member for limiting fixation, and then the second card arranged at the other end of the second connecting member is inserted into the limiting groove of another first connecting member for limiting fixation, and finally the head frame and the foot frame are installed to complete the assembly of the bed frame; however, the structures of the first card of the first connecting member and the second card of the second connecting member in this scheme are relatively complicated, and the assembly requirements are relatively high, which is not conducive to the on-site assembly of the bed frame. The patent application with publication number CN216822491U discloses a combined bed frame device, which has the effects of easy installation and stable installation by inserting the support frame into the opening and the solid part into the slot; however, in this scheme, the two ends of the support frame need to be inserted into the opening of the longitudinal frame. Since the support frame and the longitudinal frame are rigid and difficult to bend, when installing the support frame, especially the last few supports, since the distance between the two longitudinal frames is basically determined, it is difficult for the installer to insert the support frame into the opening of the longitudinal frame, which is not conducive to the on-site bed frame assembly. Utility Model Content

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a combined bed frame which is easy and quick to assemble and has a simple overall structure.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

By setting a fixing plate in the longitudinal rod, the crossbar, the second connection seat and the longitudinal rod can be fixedly connected by fasteners, and the assembly is stable.

[0015] Preferably, a blocking piece is provided at each end of the cross bar, so that the structure inside the cross bar is shielded and the overall appearance is more beautiful.

[0016] Preferably, the third connecting seat has a third U-shaped socket opening upward, and the two longitudinal rod units of each longitudinal rod are inserted into the third U-shaped socket of the third connecting seat, and the two longitudinal rod units are respectively fixed to the third connecting seat by fasteners. In this way, by providing the third connecting seat with the third U-shaped socket, the middle position of the two longitudinal rods is strengthened.

[0017] Preferably, an intermediate rod is further included, and a fourth connecting seat is provided on the inner side wall of the third connecting seat, and the fourth connecting seat has a fourth U-shaped socket opening upward, and the two ends of the intermediate rod are respectively supported and arranged in the fourth U-shaped sockets of the corresponding fourth connecting seat.

[0042] Compared with the complicated plug-in parts in the prior art or the structure that requires the two ends of the support rod to extend into the longitudinal rod, the support rod 4 and the first connecting seat 3 of the utility model have no complicated structure. Figure 2As shown, when installing the support rod 4, both ends of the support rod 4 can be clamped in the first U-shaped socket 31 of the first connecting seat 3 from top to bottom, which has a simple structure and is easy to assemble.

[0043] In order to reduce the weight of the bed frame and lower the cost of the bed frame, the crossbar 1, the longitudinal bar 2, the support bar 4 and the column 6 are all square tubes.

[0044] A cover 41 is respectively provided at both ends of the support rod 4 . In order to increase the smoothness of the support rod 4 when being inserted into the first U-shaped socket 31 of the first connecting seat 3 , a guiding inclined surface 311 is provided at the first U-shaped socket 31 of the first connecting seat 3 .

In this way, the middle position of the longitudinal rod 2 is stably supported by the third connecting seat 7 with the third U-shaped socket, so that the middle position of the longitudinal rod 2 is strengthened.

[0049] It also includes an intermediate rod 9, which adopts a square tube structure. A fourth connecting seat 8 is provided on the inner side wall of the third connecting seat 7. The fourth connecting seat 8 has a fourth U-shaped socket 81 opening upward. Both ends of the intermediate rod 9 are respectively supported and arranged in the fourth U-shaped socket 81 of the corresponding fourth connecting seat 8. The intermediate rod 9 and the longitudinal rod 2 are assembled by arranging the fourth connecting seat 8 with the fourth U-shaped socket 81.
