DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0026] Embodiment 1: refer to Figures 1-5 A bottom frame, the structure of which comprises a bed frame 1, a moving ring 2 is slidably connected inside the bed frame 1, the top of the moving ring 2 extends above the bed frame 1, and a bed plate 3 is fixedly installed. In addition, the soft bed bottom frame further comprises a lifting mechanism and a transmission mechanism.

[0027] The lifting mechanism is installed inside the moving ring 2. Specifically, the lifting mechanism comprises a support frame 5 fixedly installed inside the moving ring 2. Two transmission rods 6 are symmetrically and slidably connected to the support frame 5. Each transmission rod 6 is connected with a set of connecting rod assemblies. Each set of connecting rod assemblies comprises a plurality of rotating rods 7 rotatably connected at equal intervals at the bottom of the transmission rod 6. The bottom ends of the rotating rods 7 extend below the moving ring 2 and are collectively and fixedly connected with a support shaft 8 located inside the bed frame 1. The two ends of the support shaft 8 are rotatably connected with the two inner walls of the bed frame 1. After the connecting rod assemblies receive the driving force of the transmission mechanism, the transmission rod 6 can be driven to move upward or downward in an arc shape. Since the transmission rod 6 is horizontally slidably connected with the support frame 5, this arc-shaped movement will be converted into the longitudinal movement of the support frame 5, thereby driving the moving ring 2 to move longitudinally, and finally realizing the adjustment of the height of the bed plate 3.

[0028] In addition, the embodiment also provides a soft bed which comprises the soft bed bottom frame and a mattress 4 placed on the bed plate 3.

[0029] The application can be used in the field of furniture technology and other fields applicable to the application.

[0030] Embodiment 2: Reference Figures 3-5 On the basis of the first embodiment, the soft bed bottom frame is improved and applied to the field of furniture technology, and the transmission mechanism is installed on the inner wall of one side of the bed frame 1. Specifically, the transmission mechanism comprises a mounting box 10 fixedly installed on the inner wall of the bottom of one side of the bed frame 1. Threaded assemblies are installed on the inner walls of both sides of the mounting box 10, and each threaded assembly comprises a screw rod 15 rotatably connected to the inner wall of one side of the mounting box 10. The two screw rods 15 are jointly connected at the ends close to each other, and a transmission shaft 12 is fixedly sleeved with a worm wheel 14. A rotating shaft 11 is rotatably connected to the inner wall of one side of the mounting box 10, and a worm gear 13 engaged with the worm wheel 14 is fixedly sleeved on the rotating shaft 11. One end of the rotating shaft 11 penetrates through the inner wall of one side of the bed frame 1 and extends to the outside of the bed frame 1, and a hand wheel 19 is fixedly installed at the end. A moving plate 16 and a nut 17 threadedly connected to the moving plate 16 are respectively sleeved on each screw rod 15, and the nut 17 is fixedly installed on one side of the moving plate 16. The top of the moving plate 16 extends above the mounting box 10 and is fixedly installed with a rack 18. The two racks 18 are respectively engaged with the gears 9 fixedly sleeved on the support shafts 8.

[0031] When the hand wheel 19 is rotated, the rotating shaft 11 and the worm gear 13 are driven to rotate. Since the worm gear 13 is engaged with the worm wheel 14, the rotation of the worm gear 13 drives the worm wheel 14 and the transmission shaft 12 to rotate. The rotation of the transmission shaft 12 further drives the two screw rods 15 to rotate. Since the nut 17 is threadedly connected with the screw rod 15 and the nut 17 is fixedly installed on the moving plate 16, the rotation of the screw rod 15 is converted into the lateral movement of the moving plate 16. The lateral movement of the moving plate 16 drives the rack 18 to move laterally, and since the rack 18 is engaged with the gear 9, the lateral movement of the rack 18 is converted into the rotation of the gear 9 and the support shaft 8. The rotation of the support shaft 8 drives the multiple rotating rods 7 thereon to rotate upward or downward, thereby driving the transmission rods 6 to perform arc-shaped movement, and finally realizing the adjustment of the height of the bed plate 3.

[0032] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
