DETAILED DESCRIPTION

[0020] 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.

Embodiment 1

[0021] As shown in FIGS. 1-2, The multifunctional folding chair comprises a bed frame 1, folding legs 13, overturning blocks 20, overturning grooves 21 and overturning rods 22. The bed frame 1 is a partitional bed frame structure hinged by a plurality of folding blocks 2. The folding legs 13 are hinged to two ends of the bed frame 1 through the overturning blocks 20, and each overturning block 20 is provided with an overturning groove 21. The overturning rod 22 is fixedly connected to the bed frame 1, and the overturning rod 22 is slidably connected with the overturning groove 21. The folding leg 13 comprises a rotating rod 14, an auxiliary wheel seat 15, an auxiliary wheel shaft 16, an auxiliary wheel 17 and an anti-sliding pad 18. The rotating rod 14 is rotatably clamped with the middle portion of the folding leg 13, the auxiliary wheel seat 15 is fixedly connected to the top of the rotating rod 14, and the auxiliary wheel 17 is rotatably connected to the auxiliary wheel seat 15 through the auxiliary wheel shaft 16. The anti-sliding pad 18 is fixedly connected to the bottom of the rotating rod 14, a side edge of the folding block 2 is connected to a cross-rod connecting plate 25 and a cross rod 26, and the two ends of the cross rod 26 are connected to the cross-rod connecting plate 25. The bed frame 1 may be an integrally formed structure, or may be formed by assembling a plurality of parts using elbow members.

[0022] 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.

[0023] The folding block 2 realizes folding and unfolding of the bed frame 1, thereby improving the convenience of the folding chair.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] Finally, it should be noted that the above embodiments are merely used to illustrate the technical solution of the present invention and not to limit it. Although the present invention has been described in detail in preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be equivalently modified or replaced without departing from the purpose and scope of the technical solution of the present invention.
