    DETAILED DESCRIPTION OF THE EMBODIMENTS

    [0029] The implementations of the present disclosure will be explained in detail below in conjunction with the accompanying drawings and embodiments, so that an implementation process of how to solve the technical problems using the technical means and achieve the technical effects in the present disclosure can be fully understood and implemented.

    [0030] Referring to FIG. 1 to FIG. 6, an embodiment of the present disclosure provides a folding bed with stretchable supporting legs, including a folding bed plate and bed leg assemblies 700. Two opposite sides of the folding bed plate are hinged with expansion bed plates 600. The bed leg assemblies 700 are arranged at two ends of a bottom of the folding bed plate. Each bed leg assembly 700 includes a square tube 701. Adjustment rods 703 are slidably plugged into two ends of the square tube 701. A supporting leg 704 is fixedly mounted at one end of each adjustment rod 703 away from the square tube 701 through a bolt. A U-shaped elastic sheet 705 is arranged inside each adjustment rod 703. Fixed ends of the U-shaped elastic sheets 705 are fixedly connected to inner walls of the adjustment rods 703. Clamping heads 706 are formed at movable ends of the U-shaped elastic sheets 705. A plurality of adjustment holes 7011 are provided in one side of each square tube 701. The clamping heads 706 are able to be clamped into the adjustment holes 7011.

    [0031] When a transverse width of the folding bed needs to be adjusted, the adjustment rods 703 are pulled outwards, and the adjustment rods 703 slide inside the square tubes 701. In this case, the clamping heads 706 of the U-shaped elastic sheets 705 are compressed to deform, and are separated from the current adjustment holes 7011. After the adjustment rods 703 are pulled to appropriate positions, the U-shaped elastic sheets 705 recover its elasticity, and the clamping heads 706 are re-clamped into the adjustment holes 7011 at the corresponding positions, thereby fixing a transverse distance of the bed leg assemblies 700. Through this structure, distances between the bed legs can be flexibly adjusted according to an unfolded state of the expansion bed plates 600, thereby ensuring stability of the folding bed in different usage states.

    [0032] In this embodiment, the folding bed plate includes a first hip bed plate 100, a second hip bed plate 101, a leg bed plate 200, a bed-end bed plate 300, and a head bed plate 400. One side of the first hip bed plate 100 is hinged to the head bed plate 400, and another side of the first hip bed plate 100 is hinged to the second hip bed plate 101. One side of the second hip bed plate 101 away from the first hip bed plate 100 is hinged to the leg bed plate 200. One side of the leg bed plate 200 away from the second hip bed plate 101 is hinged to the bed-end bed plate 300.

    [0033] Due to the hinged connection between the bed plates, when the folding bed needs to be stored, the first hip bed plate 100, the second hip bed plate 101, the leg bed plate 200, the bed-end bed plate 300, and the head bed plate 400 can be folded and fitted in sequence by rotating hinged parts, thereby reducing the volume of a bed body and facilitating storage and transportation. During use, the bed plates are unfolded to form a flat sleeping plane.

    [0034] In this embodiment, the folding bed plate further includes a first electric push rod 500 and a second electric push rod 501. One end of the first electric push rod 500 is hinged to the head bed plate 400. An end portion of a piston rod of the first electric push rod 500 is hinged to the first hip bed plate 100. One end of the second electric push rod 501 is hinged to the leg bed plate 200. A piston rod of the second electric push rod 501 is hinged to the second hip bed plate 101.

    [0035] By controlling extension and contraction of the first electric push rod 500 and the second electric push rod 501, angles of the bed plates can be changed. For example, when the folding bed needs to be adjusted to a backrest mode, the first electric push rod 500 extends to push the first hip bed plate 100 to rotate around the hinged part between the first hip bed plate 100 and the head bed plate 400, thus forming an angle between the head bed plate 400 and the first hip bed plate 100. Meanwhile, the second electric push rod 501 can appropriately extend and contract to adjust angles of the leg bed plate 200 and the second hip bed plate 101, to meet different user needs, such as sitting, lying down, and half-sitting. In addition, during transportation, an occupied space can be saved by shortening the bed leg assemblies, thereby saving transportation costs.

    [0036] In this embodiment, each bed leg assembly 700 further includes a connecting rod 702. One end of the connecting rod 702 is fixedly connected to the square tube 701. One end, away from the square tube 701, of the connecting rod 702 in one bed leg assembly 700 is fixedly connected to the first hip bed plate 100. One end, away from the square tube 701, of the connecting rod 702 in the other bed leg assembly 700 is fixedly connected to the second hip bed plate 101.

    [0037] The connecting rods 702 play a role in connecting the bed leg assemblies 700 to the folding bed plate. After the square tubes 701 are fixedly connected to the first hip bed plate 100 and the second hip bed plate 101, the bed leg assemblies 700 can stably support the bed plates. When the angles of the bed plates are changed, for example, when the angles are adjusted through the electric push rods or are enlarged through the bed plates, the bed leg assemblies 700 keep synergistic movement with the bed plates through the connecting rods 702, to ensure stability of the overall structure and avoid separation between the bed legs and the bed plates or avoid shaking.

    [0038] In this embodiment, a connecting plate 707 is hinged to the connecting rod 702 fixedly connected to the second hip bed plate 101, and another end of the connecting plate 707 is hinged to the bed-end bed plate 300.

    [0039] When tilting angles of the legs of a user need to be adjusted, the piston rod of the second electric push rod 501 is controlled to extend. Since the bed-end bed plate 300 is hinged to the connecting rods 702 through the connecting plates 707, as the piston rod of the second electric push rod 501 extends, a hinged part between the bed-end bed plate 300 and the leg bed plate 200 is arched upwards to form an inverted V shape.

    [0040] When a tilting angle of the head bed plate 400 needs to be adjusted, the piston rod of the first electric push rod 500 is controlled to extend. As the piston rod of the first electric push rod 500 extends, the head bed plate 400 rotates around a hinged point between the head bed plate 400 and the first hip bed plate 100, so that one end of the head bed plate 400 away from the first hip bed plate 100 is lifted up.

    [0041] In this embodiment, two connecting rods 702 are arranged in each bed leg assembly 700, and the two connecting rods 702 are fixedly connected to two ends of the square tube 701.

    [0042] The two connecting rods 702 are fixedly connected to the two ends of each square tube 701 respectively, thus enhancing stability of connection between the bed leg assembly 700 and the bed plate. When a pressure is applied to the bed body, the two connecting rods 702 can more uniformly transmit the pressure to the square tube 701 and the supporting legs 704, to avoid avoiding structural deformation or damage caused by the pressure being applied to a single point. Meanwhile, during the adjustment of the transverse spacing of the bed leg assembly 700, the two connecting rods 702 work synergistically to ensure that the bed leg assembly 700 always maintains a good connection with the bed plates, thereby improving stability and reliability of the entire folding bed.
