Description

Technical Field

[0001] This utility model relates to the field of folding bed technology, and in particular to a folding bed with retractable legs. Background Technology

[0002] In today's living and working environments, folding beds, as a flexible and convenient type of furniture, are widely used in various fields, such as home spare beds and medical care equipment.

[0003] For example, the integrated folding bed disclosed in Chinese utility model patent CN211748299U includes a bed body, bed legs and a bed frame. The bed body is composed of multiple foldable main bed boards connected in sequence. The sides of the main bed boards are integrally provided with extension bed boards for widening. The main bed boards and the extension bed boards are connected by hinges. The two flaps of the hinges are fixedly installed on the upper surfaces of the main bed boards and the extension bed boards respectively, and the pins of the hinges are set upwards.

[0004] The aforementioned folding beds have revealed numerous problems that urgently need to be addressed during actual use. For example, the bed legs are fixed structures, and when the extension board is used, the bed area increases significantly, making it impossible to adjust the originally fixed bed legs accordingly. Because the bed legs remain in the same position after extension, the center of gravity shifts, making the bed prone to swaying and tipping under pressure, seriously affecting safety.

[0005] Therefore, we propose a folding bed with retractable legs. Utility Model Content

[0006] The purpose of this invention is to provide a folding bed with retractable legs, thereby solving or at least alleviating one or more of the aforementioned problems and other issues existing in the prior art.

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0029] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0030] Please refer to Figures 1 to 6As shown, an embodiment of this utility model provides a folding bed with retractable legs. It is characterized by including a foldable bed board and a leg assembly 700. Extendable bed boards 600 are hinged to opposite sides of the foldable bed board, and leg assemblies 700 are provided at both ends of the bottom of the foldable bed board. The leg assembly 700 includes a square tube 701, with adjusting rods 703 slidably inserted into both ends of the square tube 701. A leg 704 is fixedly installed at the end of the adjusting rod 703 away from the square tube 701 by bolts. A U-shaped elastic piece 705 is provided inside the adjusting rod 703. The fixed end of the U-shaped elastic piece 705 is fixedly connected to the inner wall of the adjusting rod 703, and a locking head 706 is formed at the movable end of the U-shaped elastic piece 705. Several adjusting holes 7011 are provided on one side of the square tube 701, and the locking head 706 can be inserted into the adjusting holes 7011.

[0031] When the lateral width of the folding bed needs to be adjusted, the adjusting rod 703 is pulled outward. The adjusting rod 703 slides inside the square tube 701. At this time, the locking head 706 of the U-shaped elastic piece 705 is compressed and deformed, disengaging from the currently engaged adjusting hole 7011. After the adjusting rod 703 is pulled to the appropriate position, the U-shaped elastic piece 705 regains its elasticity, and the locking head 706 re-engages into the corresponding adjusting hole 7011, thus fixing the lateral spacing of the bed leg assembly 700. Through this structure, the spacing of the bed legs can be flexibly adjusted according to the unfolded state of the extended bed board 600, ensuring the stability of the folding bed under different usage conditions.

[0032] In this embodiment, the foldable bed board includes a first hip bed board 100, a second hip bed board 101, a leg bed board 200, a foot bed board 300, and a head bed board 400. One side of the first hip bed board 100 is hinged to the head bed board 400, and the other side of the first hip bed board 100 is hinged to the second hip bed board 101. The side of the second hip bed board 101 away from the first hip bed board 100 is hinged to the leg bed board 200, and the side of the leg bed board 200 away from the second hip bed board 101 is hinged to the foot bed board 300.

[0033] Because the bed boards are connected by hinges, when the folding bed needs to be stored, the first hip bed board 100, the second hip bed board 101, the leg bed board 200, the foot bed board 300, and the head bed board 400 can be folded and fitted together in sequence by rotating each hinge, reducing the size of the bed and making it easier to store and move. When in use, the bed boards are unfolded to form a flat sleeping surface.

[0034] In this embodiment, the foldable bed board also 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 headboard 400, and the piston rod end of the first electric push rod 500 is hinged to the first hipboard 100. One end of the second electric push rod 501 is hinged to the legboard 200, and the piston rod of the second electric push rod 501 is hinged to the second hipboard 101.

[0035] By controlling the extension and retraction of the first electric push rod 500 and the second electric push rod 501, the angle of the bed board can be changed. For example, when the folding bed needs to be adjusted to the backrest mode, the first electric push rod 500 extends, pushing the first hip bed board 100 to rotate around the hinge point with the head bed board 400, so that the head bed board 400 and the first hip bed board 100 form a certain angle; at the same time, the second electric push rod 501 extends and retracts appropriately to adjust the angle of the leg bed board 200 and the second hip bed board 101 to meet different user needs, such as sitting, lying down, or semi-reclining. In addition, during transportation, the bed leg assembly can be shortened to save space, thereby saving transportation costs.

[0036] In this embodiment, the bed leg assembly 700 further includes a connecting rod 702, one end of which is fixedly connected to the square tube 701. In one set of bed leg assemblies 700, the end of the connecting rod 702 away from the square tube 701 is fixedly connected to the first buttock bed board 100, and in another set of bed leg assemblies 700, the end of the connecting rod 702 away from the square tube 701 is fixedly connected to the second buttock bed board 101.

[0037] The connecting rod 702 connects the bed leg assembly 700 to the foldable bed board. After the square tube 701 is fixedly connected to the first hip bed board 100 and the second hip bed board 101, the bed leg assembly 700 can stably support the bed board. When the angle of the bed board changes, such as when adjusted by an electric push rod or when the bed board is extended, the bed leg assembly 700 moves in tandem with the bed board through the connecting rod 702, ensuring the stability of the overall structure and preventing the bed legs from detaching from the bed board or from wobbling.

[0038] In this embodiment, a connecting plate 707 is hinged to the connecting rod 702, which is fixedly connected to the second buttock bed board 101, and the other end of the connecting plate 707 is hinged to the footboard 300.

[0039] When it is necessary to adjust the leg tilt angle, the piston rod of the second electric push rod 501 is extended. Since the footboard 300 is hinged to the connecting rod 702 through the connecting plate 707, as the piston rod of the second electric push rod 700 extends, the hinge point between the footboard 300 and the legboard 200 arches upward to form an inverted V shape.

[0040] When it is necessary to adjust the tilt angle of the headboard 400, the piston rod of the first electric push rod 500 is extended. As the piston rod of the first electric push rod 500 extends, the headboard 400 rotates at the hinge point between the headboard 400 and the first hipboard 100, so that the end of the headboard 400 away from the first hipboard 100 is lifted.

[0041] In this embodiment, the bed leg assembly 700 has two connecting rods 702, which are fixedly connected to both ends of the square tube 701.

[0042] Two connecting rods 702 are fixedly connected to both ends of the square tube 701, enhancing the connection stability between the bed leg assembly 700 and the bed board. When the bed is under pressure, the two connecting rods 702 can more evenly transmit the pressure to the square tube 701 and the support legs 704, avoiding structural deformation or damage caused by single-point force. At the same time, when adjusting the lateral spacing of the bed leg assembly 700, the two connecting rods 702 work together to ensure that the bed leg assembly 700 and the bed board always maintain a good connection, improving the stability and reliability of the entire folding bed.
