The transverse side bars and longitudinal side bars are usually arranged as two parallel bars, and the two ends of the transverse side bars and longitudinal side bars are respectively connected to the supporting legs to form a bed frame.

[0003] The support legs, a crucial component of the bed frame, are designed to facilitate detachable assembly with the side rails. Bolts are located at the top of the legs, and bolt holes are provided in the side rails. These two rails are connected via a threaded connection for detachable assembly.

Instead, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0045] Example 1

[0046] like Figures 1 to 9 As shown, an assembly structure of a support leg and a side rod according to an embodiment of the present invention is suitable for a bed frame, especially a metal bed frame, and includes a support leg 1, a connecting piece 2 and a side rod 3.

[0047] The support leg 1 includes a side wall 11 and a hollow portion 12 surrounded by the side wall 11. The side wall 11 is provided with a first slot 13 communicating with the hollow portion 12. The cross section of the support leg 1 can be fan-shaped, such as Figure 1 As shown, the cross section of the support foot 1 can also be rectangular, such as Figure 5As shown, it can also be a triangle, a pentagon, etc. The first slot 13 can be a rectangular slot, and the first slot 13 is provided on two adjacent surfaces of the side wall 11 of the support leg 1.

[0048] The connecting piece 2 can be inserted into the hollow portion 12 of the supporting leg 1. The connecting piece 2 is provided with a second slot 21 adapted to the first slot 13. That is, the second slot 21 of the connecting piece 2 is positioned opposite the first slot 13 of the supporting leg 1 and can be of equal size. When the connecting piece 2 is inserted into the hollow portion 12 of the supporting leg 1, the second slot 21 of the connecting piece 2 communicates with the first slot 13 of the supporting leg 1. The second slot 21 can be a rectangular slot.

[0049] Optionally, the connecting piece 2 has an L-shaped cross-section and includes adjacent first and second contact surfaces 22, 23. The first and second contact surfaces 22, 23 respectively abut against the interior of different adjacent side walls 11 of the support leg 1. The first and second contact surfaces 22, 23 are respectively provided with second slots 21. The first and second contact surfaces 22, 23 are respectively provided with first slots 13 on different adjacent side walls 11 of the support leg 1, and the first slots 13 correspond one-to-one with the second slots 21.

[0050] The end of the side rod 3 is fixedly connected to the plug-in piece 4, which can be integrally connected to the end of the side rod 3, such as by welding, or can be separately connected. The plug-in piece 4 is provided with a buckle 5. In this example, the buckle 5 is set to one, and can be set to two or more. The buckle 5 has a limiting portion 51; the buckle 5 can be inserted into the first slot 13 and the second slot 21 in sequence, so that the side wall 11 of the supporting foot 1 and the connecting piece 2 are snapped into the limiting portion 51; the plug-in piece 4 is fixedly connected to the supporting foot 1 and the connecting piece 2 in sequence through the fixing member 6.

[0051] Optionally, the clip 5 includes a first clip plate 52 radially connected to the plug-in plate 4 and a second clip plate 53 radially connected to the first clip plate 52. The second clip plate 53 is arranged parallel to the plug-in plate 4, and a stopper 51 is formed between the second clip plate 53 and the plug-in plate 4. The distance between the second clip plate 53 and the plug-in plate 4 is equivalent to the sum of the thickness of the side wall 11 of the support leg 1 and the thickness of the connecting plate 4, so that the side wall 11 of the support leg 1 and the connecting plate 2 can be precisely snapped into the stopper 51, thereby ensuring a tight fit between the clip 5 and the support leg 1 and improving support stability.

[0052] Optionally, the first slot 13 of the support leg 1, the second slot 21 of the connecting plate 2, and the buckle 5 are all provided as one, and the fixing member 6 includes a first bolt hole 41 provided on the plug-in plate 4, a second bolt hole 14 provided on the side wall 11 of the support leg 1, a threaded hole 24 provided on the connecting plate 2, and a bolt 61 that passes through the first bolt hole 41 and the second bolt hole 14 and connects to the threaded hole 24 in sequence. Specifically, second bolt holes 14 are provided on adjacent different side walls 11 of the support leg 1, and the second bolt holes 14 are located below the first slot 13. Correspondingly, threaded holes 24 are provided on the first contact surface 22 and the second contact surface 23 of the L-shaped connecting plate 2, and the threaded holes 24 are located below the second slot 21. The fixing member 6 can also be other structures, such as a metal rod, rivet, or screw that directly connects the first bolt hole 41 on the plug-in plate 4, the second bolt hole 14 on the side wall 11 of the support leg 1, and the threaded hole 24 on the connecting plate 2.

[0053] In an embodiment of the present invention, an assembly structure of a support foot and a side rod is provided. Since the end of the side rod 3 is fixedly connected to the plug-in piece 4, the plug-in piece 4 is provided with a buckle 5. The buckle 5 can be inserted into the first slot 13 and the second slot 21 in sequence, so that the side wall 11 of the support foot 1 and the connecting piece 2 are snapped into the limit portion 51. The plug-in piece 4 is fixedly connected to the support foot 1 and the connecting piece 2 in sequence by the fixing member 6. This makes the structure simple and stable, and effectively solves the problems of shaking and friction noise. Specifically, the connecting piece 2 is provided inside the side wall 11 of the support foot 1, which can effectively improve the strength of the connection. After the plug-in piece 4 is fixedly connected to the support foot 1 and the connecting piece 2 in sequence by the fixing member 6, the buckle 5 and the support foot 1 and the connecting piece 2 cooperate tightly, effectively improving the problems of shaking and friction noise.

[0054] During installation, the buckle 5 on the plug-in plate 4 passes through the corresponding rectangular grooves on the supporting foot 1 and the connecting plate 2 to connect the side rod 3 to the supporting foot 1. At this time, a screw or bolt 61 is used to pass through the first bolt hole 41, the second bolt hole 14 and the bolt hole 24 corresponding to the supporting foot 1, the connecting plate 2 and the plug-in plate 4 to further strengthen the connection and effectively improve the strength of the connection. After the screw or bolt 61 is completely locked in, the buckle 5 and the supporting foot 1 fit very tightly, effectively improving the problem of shaking and friction noise of the bed frame.

[0055] like Figure 8 and Figure 9 As shown, the first slot 13 of the support leg 1, the second slot 21 of the connecting piece 2, and the buckle 5 are each provided in pairs. The fixing member 6 includes a supporting member 62 provided on the outside of the side wall of the support leg 2. The supporting member 62 connects the plug-in piece 4 and the side rod 3. Specifically, the supporting member 62 is provided as a U-shaped groove, and the plug-in piece 4 and the side rod 3 are placed in the U-shaped groove to provide support therefor.

[0056] Optionally, when the number of the clips 5 is greater than one, the number of the first slots 13 and the second slots 21 also increases corresponding to the number of the clips 5, and each group of the clips 5, the first slots 13 and the second slots 21 are connected through their respective limiting portions 51.

[0057] Because the end of the side rod 3 is fixedly connected to the plug-in piece 4, the plug-in piece 4 is provided with a buckle 5. The buckle 5 can be sequentially inserted into the first slot 13 and the second slot 21, so that the side wall 11 of the support leg 1 and the connecting piece 2 are locked into the limit portion 51. The plug-in piece 4 is connected to the support leg 1 via the fixing member 6, resulting in a simple structure, good stability, and effectively solving the problems of shaking and friction noise. Specifically, the connection piece 2 is provided inside the side wall 11 of the support leg 1, which can effectively improve the strength of the connection. After the plug-in piece 4 is connected to the support leg 1 via the fixing member, the buckle 5, the support leg 1, and the connecting piece 2 cooperate tightly, effectively reducing the shaking and friction noise problems.

[0058] During installation, the buckle 5 on the connector 4 passes through the corresponding first slot 13 and second slot 21 on the support leg 1 and the connecting piece 2, connecting the side bar 3 to the support leg 1. At this time, the side bar 3 and the connector 4 are placed in the support member 62, further strengthening the connection and effectively improving the strength of the connection, effectively improving the shaking and friction noise problems of the bed frame.

[0059] Optionally, the connector 4 has an abutment surface 42. After the clip 5 is sequentially inserted into the first slot 13 and the second slot 21, the abutment surface 42 contacts the outer surface of the side wall 11 of the support leg 1. The connecting piece 2 contacts the inner surface of the side wall 11 of the support leg 1. The contact between the connector 4 and the outer surface of the side wall 11 of the support leg 1 and the contact between the connecting piece 2 and the inner surface of the side wall 11 of the support leg 1 make it less susceptible to deformation due to stress, and provide better support and durability.

[0060] Optionally, the assembly structure of the support leg and sidebar also includes a cap 7, which has the same cross-sectional shape as the support leg 1 and is mounted on the upper end surface of the support leg 1. The cap 7 is made of a soft material and can be fan-shaped, rectangular, triangular, pentagonal, or other shapes. It serves as a safety feature and, after installation, tightly covers the top of the support leg 1 to prevent cuts, sharp angles, and other hazards.

[0061] Optionally, the side bars 3 include transverse side bars 31 and longitudinal side bars 32. The ends of the transverse side bars 31 and longitudinal side bars 32 are respectively fixedly connected to the plug-in piece 4. Two adjacent side walls 11 of the support leg 1 are respectively provided with a first slot 13 that communicates with the hollow portion 12. The buckles 5 of the transverse side bars 31 and longitudinal side bars 32 can be sequentially inserted into the first slot 13 and the second slot 31, respectively, so that the side walls 11 of the support leg 1 and the connecting piece 2 are snapped into the limiting portion 51. Specifically, the longitudinal side bars 32 are provided with a radially extending stepped portion 321 for connecting to the bed board inside the bed frame.

Optionally, the side bars 3 include a transverse side bar 31 and a longitudinal side bar 32, and the transverse side bar 31 and the longitudinal side bar 32 are respectively arranged in parallel. The ends of the transverse side bar 31 and the longitudinal side bar 32 are respectively fixedly connected to the plug-in piece 4, and the ends of the transverse side bar 31 and the longitudinal side bar 32 are respectively connected to the support leg 1 through the plug-in piece 4; the two adjacent side walls 11 of the support leg 1 are respectively provided with a first slot 13 connected to the hollow portion 12, and the buckles 5 of the transverse side bar 31 and the longitudinal side bar 32 can be inserted into the first slot 13 and the second slot 21 in sequence, so that the side wall 11 of the support leg 1 and the connecting piece 2 are respectively engaged with the limiting portion 51.

[0064] like Figure 12 As shown, specifically, the bed frame also includes a transverse reinforcing side rod 33 and a longitudinal reinforcing side rod 34. The two ends of the transverse reinforcing side rod 33 are respectively connected to the supporting foot 1 and are arranged parallel to the transverse side rod 31; the two ends of the longitudinal reinforcing side rod 34 are respectively connected to the supporting foot 1 and are arranged parallel to the longitudinal side rod 32.

Since the end of the side rod 3 is fixedly connected to the plug-in piece 4, the plug-in piece 4 is provided with a buckle 5. The buckle 5 can be inserted into the first slot 13 and the second slot 21 in sequence, so that the side wall 11 of the support leg 1 and the connecting piece 2 are snapped into the limit portion 51. The plug-in piece 4 is fixedly connected to the support leg 1 and the connecting piece 2 in sequence through the fixing piece 6, making the structure simple and stable, and effectively solving the problems of shaking and friction noise. Specifically, the connecting piece 2 is provided inside the side wall 11 of the support leg 1, which can effectively improve the strength of the connection. After the plug-in piece 4 is fixedly connected to the support leg 1 through the fixing piece 6, the buckle 5 and the support leg 1 and the connecting piece 2 cooperate tightly, effectively improving the problems of shaking and friction noise.
