In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0040] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0041] Such as Figure 1-7As shown in the figure, the embodiment of the present utility model provides a folding bed frame, which includes a main frame 1, a backrest support 2, a foot support frame 3, and a gear adjustment component 4; wherein the backrest support 2 is used to support the back and head of the user, one end is rotatably arranged on the main frame 1, and the other end is free. The gear adjustment component 4 is used to adjust the rotation angle of the backrest. When the angle of the backrest needs to be adjusted, it can be achieved only by operating the gear adjustment component 4; wherein the foot support frame 3 is used to support the main frame 1, one end is free, and the other end is rotatably arranged on the inner side wall of the main frame 1. When it needs to be used, only the foot support frame 3 needs to be rotated away from the main frame 1 until it reaches a certain angle. When it needs to be folded, only the foot support frame 3 needs to be rotated towards the main frame 1 until it rotates to the horizontal direction. Because the end of the foot support frame 3 is rotatably arranged on the inner side of the main frame 1, after the foot support frame 3 rotates, the whole foot support frame 3 will rotate to the inner side of the main frame 1, so that it will not protrude to the outside of the main frame 1. Compared with the existing situation where the end of the foot support frame 3 is connected to the inner side of the main frame 1 and the foot support frame 3 will be located outside the bottom of the main frame 1 after rotation and folding, the overall thickness of the entire folding bed frame will be reduced after folding. Therefore, when storing or carrying, the occupied space will be reduced, and the number of storage or carrying in the same space will be more.

[0042] Specifically, the main frame 1 includes two main support rods 11. A plurality of first connecting rods 12 are arranged between the two main support rods 11. The middle part of the first connecting rod 12 is an arc structure, which is used to increase the support strength of the overall main frame 1. Moreover, both ends of the first connecting rod 12 are rotatably connected to the two main support rods 11 respectively. After unfolding, the arc structure of the first connecting rod 12 faces perpendicular to the main frame 1, which is used to increase the support strength of the main frame 1. When folding is needed, only the arc structure of the first connecting rod 12 needs to be made to face parallel to the support frame, so that the first connecting rod 12 is completely located inside the two main support rods 11. Thus, after folding, the arc structure of the first connecting rod 12 will not increase the overall thickness.

[0043] Specifically, the foot support frame 3 includes a foot rotating frame and a limiting member. The foot rotating frame includes a second connecting rod 32 and two foot support rods 31. The two foot support rods 31 are connected by the second connecting rod 32 to form a whole. One ends of the two foot support rods 31 are respectively rotatably connected to the inner side walls of the two main support rods 11, and the other ends are free, so that the entire foot rotating frame can rotate relative to the main frame 1. Correspondingly, there are two limiting members, and the two limiting members cooperate with the two foot support rods 31 respectively to limit the rotation angle of the foot support rods 31 when they are unfolded. Specifically, the limiting member includes a limiting plate 33. One end of the limiting plate 33 is rotatably connected to the inner side wall of the main support rod 11. A limiting sliding hole 34 is provided on the limiting plate 33, and a sliding rod 35 is provided on the foot support rod 31. The sliding rod 35 is inserted into the limiting sliding hole 34. The length of the limiting sliding hole 34 determines the rotation angle of the foot support rod 31. When the foot support rod 31 is unfolded, the rotation directions of the foot support rod 31 and the limiting plate 33 relative to the main support rod 11 are opposite, and both rotate away from the main support rod 11. Finally, the sliding rod 35 moves from one end of the limiting sliding hole 34 to the other end until the sliding rod 35 moves to the other end of the limiting sliding hole 34, and the foot support rod 31 rotates to the maximum angle. When folding, similarly, the rotation directions of the foot support rod 31 and the limiting plate 33 relative to the main support rod 11 are opposite, and both rotate towards the main support rod 11 until the foot support rod 31 rotates to the folding direction.

[0044] Specifically, a rotating member 5 is provided at one end of the foot support rod 31. The foot support rod 31 is rotatably connected to the main support rod 11 through the rotating member 5. In order to make the limiting plate 33 and the foot support rod 31 both located inside the two main support rods 11 after folding, the connecting end of the rotating member 5 located outside the foot support rod 31 is located outside the side wall of the foot support rod 31. When the rotating member 5 is rotatably connected to the main support rod 11, a space for placing the rotated limiting plate 33 is formed between the foot support rod 31 and the main support rod 11. Thus, during the folding process of the limiting plate 33 and the foot support rod 31, the rotation directions of the foot support rod 31 and the limiting plate 33 relative to the main support rod 11 are opposite, and both rotate towards the main support rod 11. Finally, after folding is completed, the foot support rod 31 and the limiting plate 33 are both located inside the two main support rods 11, and the limiting plate 33 is located between the foot support rod 31 and the main support rod 11, making the folded structure more compact and the space utilization more isolated. Specifically, the rotating member 5 is a plastic part. The rotating member 5 includes an insertion part 51 and a connecting part 52. The insertion part 51 is inserted into the foot support rod 31 and connected by bolts. The connecting end is located outside the foot support rod 31 and is located laterally outside the side wall of the foot support rod 31. Thus, after the connecting part 52 is rotatably connected to the main support rod 11, the foot support rod 31 and the main support rod 11 can be spaced apart.

[0045] Specifically, the backrest support 2 includes a third connecting rod 22 and two backrest support rods 21. The two backrest support rods 21 are connected by the third connecting rod 22 to form an integral body. One ends of the two backrest support rods 21 are respectively rotatably connected to the inner side walls of the two main support rods 11, and the other ends are free. Correspondingly, the gear adjustment assembly 4 includes a U-shaped rod 41 and a limiting rod 44. A plurality of card slots 43 are provided on the U-shaped rod 41. Two ends of the U-shaped rod 41 are respectively rotatably connected to the inner side walls of the two backrest support rods 21. The limiting rod 44 is arranged on the foot support frame 3 close to the backrest support 2. Thus, after the overall bed frame is unfolded, by rotating the U-shaped rod 41, different card slots 43 are matched with the limiting rod 44, that is, the limiting rod 44 is snapped into the card slots 43 at different positions to realize the adjustment of the rotation angle of the backrest support 2. At the same time, the U-shaped rod 41 also acts as a support for the backrest support 2. When the limiting rod 44 is snapped into the card slot 43, the limiting rod 44 supports the U-shaped rod 41, and the U-shaped rod 41 supports the two backrest support rods 21 to realize the stability of the backrest support 2. Specifically, the U-shaped rod 41 includes two adjusting rods and a fourth connecting rod. One ends of the two connecting rods are respectively rotatably connected to the inner side walls of the two backrest support rods 21, and the other ends are respectively connected to the two ends of the fourth connecting rod. Plastic strips 42 are arranged on the side walls of the two adjusting rods facing the limiting rod 44, and a plurality of card slots 43 are arranged along the length direction of the adjusting rods on the plastic strips 42.

[0046] Preferably, an L-shaped connecting plate 6 is rotatably connected between one end of the backrest support rod 21 and the inner side wall of the main support rod 11. The backrest support rod 21 and the main support rod 11 are connected by the L-shaped connecting plate 6, which can increase the freedom degree of installation of the backrest support rod 21. Moreover, after folding, the backrest support rod 21 can be raised to a certain height to avoid the foot support frame 3 and provide a storage space for the foot support frame 3 after folding, that is, inside the main support rod 11. In this way, the length of the entire main frame 1 can be shortened because there is an overlapping part between the foot support rod 31 and the backrest support rod 21 in the top view after folding, so that the overall length is shortened, and thus the overall storage space is shortened.

[0047] As Figure 8-9 shown, the present utility model also provides a folding bed, which includes a bed cloth 7 and the above-mentioned folding bed frame. The bed cloth 7 is arranged on the support surface formed by the main frame 1 and the backrest support 2. Among them, the bed cloth 7 is connected to the main support rod 11 and the backrest support rod 21. The connection method can be through ropes or other well-known connection methods.

[0048] The above embodiments are only the preferred embodiments of the present utility model, and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model belong to the protection scope required by the present utility model.
