This invention generally relates to the technical field of daily-used articles, and more particularly, to a multifunctional folding chair.
Chinese patent CN112107181A discloses a folding chair comprising a bed surface module and a first supporting leg, wherein a first connecting rod and a second connecting rod are connected between the bed surface module and the first supporting leg. The bed surface module, the first supporting leg, the first connecting rod and the second connecting rod form a four-linkage mechanism, and the four-linkage mechanism may be selected to be in a folded state or a supporting state. In the folded state, the first supporting leg is folded on the rear surface of the bed surface module. In the supporting state, the top end surface of the first supporting leg supports the bottom surface of the bed surface module. Both the first connecting rod and the second connecting rod interact with the bed surface module and the first supporting leg to form a triangular supporting structure. The aforesaid solution achieves high support strength, high stability and long functional life while realizing the self-locking under the action of gravity. Moreover, the chair is stable in an unfolded state, the design is reasonable, and the structure is compact after being folded.
However, in the prior art, most of the folding chairs adopt a single moving structure or a single fixed structure, resulting in the failure of conversion between movement and fixation such that the moving performance is poor.

The locking cylinder is mounted in the first hinge plate and the second hinge plate, the latch is arranged in the middle of the first hinge plate, and the latch is clamped with the locking block.
In another preferred embodiment of the present invention, the folding chair further comprises wheel legs and moving wheels, and the moving wheels are mounted on two sides of the middle of the bed frame through the wheel legs.
In another preferred embodiment of the present invention, the folding chair further comprises a handrail seat, a handrail rod and a handrail. The handrail seat is fixedly connected to two sides of the middle of the bed frame, the handrail rod is slidably connected to the handrail seat, and the handrail is fixedly connected to the top of the handrail rod.
In another preferred embodiment of the present invention, the folding chair further comprises support legs and a support base. The support legs are hinged to two sides of the bed frame, and the support base is fixedly connected to the bottom of the support legs.
In another preferred embodiment of the present invention, the folding chair further comprises a bed body mounted in the middle of the bed frame.
Compared with the prior art, the present invention has the following advantages: the rotating rod is mounted in the folding leg, and through the rotation of the rotating rod, the auxiliary wheel and the anti-sliding pad are switched to contact the ground; the auxiliary wheel is a universal wheel structure, which is capable of realizing the moving and turning around on the spot; the anti-sliding pad significantly improves the stability and firmness of the bed frame; the folding block is capable of realizing the folding and unfolding of the bed frame, greatly improving the convenience of the folding chair.

To allow those skilled in the art to better understand the present invention, drawings and embodiments are combined hereinafter to further elaborate the technical solution of the present invention.
As shown in
According to the present invention, the rotating rod 14 is mounted in the folding leg 13, and through the rotation of the rotating rod 14, the auxiliary wheel 17 and the anti-sliding pad 18 are switched to contact the ground. The auxiliary wheel 17 is a universal wheel structure, which is capable of realizing the moving and turning around on the spot. The anti-sliding pad 18 significantly improves the stability and firmness of the bed frame 1. The bed frame 1 is formed by assembling and splicing. Through adopting this design, the bed frame 1 becomes firmer, and the size of the bed frame 1 becomes smaller after the bed frame 1 is disassembled. The cross rod 26 is connected to the center hole of the folding block 2 through the cross-rod connecting plate 25, and the cross rod is lower than the chair cloth, making a user feel more comfortable. The folding block 2 comprises a first hinge plate 3, a second hinge plate 4, a locking block 5, a locking cylinder 23 and a latch 24, wherein the first hinge plate 3 is rotatably connected to the second hinge plate 4, and the locking block 5 is arranged on the second hinge plate 4 and is clamped with the first hinge plate 3. The locking cylinder 23 is mounted in the first hinge plate 3 and the second hinge plate 4, the latch 24 is arranged in the middle of the first hinge plate 3, and the latch 24 is clamped with the locking block 5.
The folding block 2 realizes folding and unfolding of the bed frame 1, thereby improving the convenience of the folding chair.
The folding chair of the present invention further comprises wheel legs 6 and moving wheels 7, and the moving wheels 7 are mounted on two sides of the middle of the bed frame 1 through the wheel legs 6.
The folding chair of the present invention further comprises a handrail seat 8, a handrail rod 9 and a handrail 10. The handrail seat 8 is fixedly connected to two sides of the middle of the bed frame 1, the handrail rod 9 is slidably connected to the handrail seat 8, and the handrail 10 is fixedly connected to the top of the handrail rod 9.
The folding chair of the present invention further comprises support legs 11 and a support base 12. The support legs 11 are hinged to two sides of the bed frame 1, and the support base 12 is fixedly connected to the bottom of the support legs 11. The folding chair further comprises a bed body 19 mounted in the middle of the bed frame 1, a handle 27 is arranged in the middle of the bed body 19, and the handle 27 allows the folding chair to be conveniently transported.
