[0016] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. 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 circumstances.
[0017] The following combines the embodiments and the attached Figures 1 to 3 , and further elaborates on the technical solutions of the present utility model.
[0018] Embodiment 1
[0019] A multi - part angle - adjustable folding bed, comprising: a main bracket 1, a backrest bracket 2, a leg bracket 3, a foot bracket 4, a first support frame 5 and a second support frame 6. On the left side of the upper end of the main bracket 1, there is an adjusting plate 11. At intervals on the adjusting plate 11, there are first slots 12. The backrest bracket 2 is rotatably arranged on the left side of the upper end of the main bracket 1. At the lower end of the backrest bracket 2, there is a first inserting rod 21 rotatably arranged. The lower end of the first inserting rod 21 is clamped in the first slot 12. The foot bracket 4 is slidably arranged in a first sliding groove 13 on the right side of the lower end of the main bracket 1. The foot bracket 4 includes a sliding rod 41 and an adjusting frame 42. The left end of the adjusting frame 42 is rotatably arranged in the sliding rod 41. The sliding rod 41 is slidably arranged in a second sliding groove 31 of the leg bracket 3. The first support frame 5 is rotatably arranged at the bottom end of the main bracket 1. The second support frame 6 is rotatably arranged at the lower right side of the leg bracket 3. On the second support frame 6, there is a second inserting rod 61 rotatably arranged. The second inserting rod 61 is clamped in a second slot 43 on the lower side of the adjusting frame 42. On the end faces of the main bracket 1, the backrest bracket 2, the leg bracket 3 and the foot bracket 4, there is a seat cushion 8.
[0020] As Figures 1 to 3 shown, the working principle of the present utility model: When it is necessary to adjust the support height of the head or back during use, by rotating the first inserting rod 21 of the backrest bracket 2 and inserting and clamping it in the first slots 12 at different positions of the adjusting plate 11, the angle of the backrest bracket can be conveniently adjusted. At the same time, the leg bracket 3 can adjust the extended length according to the height or posture of the user. By rotating the second inserting rod 61 of the second support frame 6 and inserting and clamping it in the second slots 43 at different positions of the adjusting frame 42, the angle of the foot bracket can be conveniently adjusted. At the same time, when not in use, the foot bracket 4 can be retracted into the bottom of the leg bracket 3, and the leg bracket 3 can be retracted into the bottom of the main bracket 1, which is convenient for subsequent storage and can be flexibly adjusted according to the user's usage method.
[0021] As a further preferred embodiment, a first limiting block 32 is fixed on the right side of the leg bracket 3, and a second limiting block 44 is arranged on the right side of the adjusting frame 42. Through the cooperation of the first limiting block 32 and the second limiting block 44, it is possible to prevent the leg bracket 3 from disengaging during the process of being retracted or extended.
[0022] As a further preferred embodiment, both the first slot 12 and the second slot 43 include a vertical rectangular slot 71 and a circular groove 72 located at the bottom of the vertical rectangular slot 71, which is convenient for the corresponding inserting rod to be guided and inserted into the slot.
[0023] As a further preferred embodiment, the backrest bracket 2 has a U - shaped cross - section, and the backrest bracket 2 is located outside the adjusting plate 11 in the vertical projection direction, so that the backrest bracket 2 can be completely laid flat to the left side of the main bracket 1.
