DETAILED DESCRIPTION

[0020] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show typical embodiments of the present invention.

[0021] Embodiment 1:

[0022] like Figure 1-4 As shown, the utility model is an improved butterfly chair that is convenient to fold, comprising a base 1, a folding assembly 2 is fixedly connected to the bottom surface of the base 1, and an adjustment assembly 3 is provided on the surface of the folding assembly 2;

[0023] The folding assembly 2 includes a recessed block 201 fixed to the bottom surface of the base 1, and a sleeve 202 is fixedly connected to the side surface of the recessed block 201, an arc groove 203 is provided on the surface of the recessed block 201, and a rotating block 204 is installed inside the recessed block 201 through a rotating shaft, a sliding groove 205 is provided on the surface of the sleeve 202, and a groove 206 is provided on the inner wall of the sliding groove 205, a spring 207 is provided inside the sleeve 202, a boss 208 is movably connected inside the sleeve 202, and a sliding column 209 is fixedly connected to the surface of the boss 208.

[0024] like Figure 1-4 As shown, a through hole 210 is opened on the surface of the rotating block 204 , and the inner wall of the through hole 210 contacts the surface of the protruding column 1 208 .

[0025] like Figure 1-4 As shown, the surface of the boss 208 contacts the inner wall of the sleeve 202, and the side surface of the boss 208 contacts the surface of the spring 207.

[0026] like Figure 1-4 As shown, there are multiple groups of recessed blocks 201, and the recessed blocks 201 are symmetrically arranged with each other. The recessed blocks 201 and the base 1 form a fixed structure through bolts.

[0027] During implementation, when folding is required, the threaded rod 312 is twisted to separate the threaded rod 312 from the lifting column 303, and the sliding column 209 is slid at the same time. The sliding column 209 drives the protruding column 208 to slide, so that the protruding column 208 is separated from the through hole 210 on the surface of the rotating block 204, and the rotating block 204 is rotated to a suitable position. At the same time, the sliding column 209 is released, and the spring 207 pushes the protruding column 208 to slide, so that the protruding column 208 is engaged with another through hole 210 on the surface of the rotating block 204, and the butterfly chair can be folded for easy carrying.

[0028] Embodiment 2:

[0029] like Figure 1-4As shown, on the basis of the first embodiment, the utility model provides a technical solution: the adjustment component 3 includes an annular column 301 fixed to the bottom surface of the rotating block 204, and the side surface of the annular column 301 is fixedly connected with a sleeve 2 302, and a lifting column 303 is arranged inside the annular column 301, and the surface of the lifting column 303 is connected with a threaded rod 312 through a thread, and the surface of the threaded rod 312 is movably connected with a sleeve 313.

[0030] like Figure 1-4 As shown, the surface of the lifting column 303 is in contact with the inner wall of the annular column 301, a plurality of limit holes 304 are provided on the surface of the lifting column 303, and a connecting plate 305 is fixedly connected to the bottom surface of the lifting column 303, a wear-resistant pad 306 is fixedly connected to the bottom surface of the connecting plate 305, and a protective pad 307 is fixedly connected to the bottom surface of the connecting plate 305.

[0031] like Figure 1-4 As shown, a second slide groove 308 is provided on the surface of the second sleeve 302 , a second spring 309 is provided inside the second sleeve 302 , a second boss 310 is movably connected inside the second sleeve 302 , and a second slide column 311 is fixedly connected to the surface of the second boss 310 .

[0032] During implementation, by sliding the second sliding column 311, the second sliding column 311 can drive the second convex column 310 to slide, and at the same time slide the lifting column 303 to a suitable position, loosen the second sliding column 311, and the second spring 309 pushes the second convex column 310 to slide, so that the second convex column 310 is engaged with the limiting hole 304 on the surface of the lifting column 303, and the height of the base 1 can be adjusted. At the same time, due to the arrangement of the threaded rod 312 and the sleeve 313, the stability between the connecting plates 305 is improved, and the height of the lifting column 303 on the other side can be adjusted to be different from the lifting column 303, so that the angle of the base 1 can be adjusted.

[0033] The advantages of this technical solution in practical applications include but are not limited to the following:

[0034] 1. By twisting the threaded rod 312, the threaded rod 312 is separated from the lifting column 303, and the sliding column 209 is slid at the same time, and the sliding column 209 drives the protruding column 208 to slide, so that the protruding column 208 is separated from the rotating block 204, and the rotating block 204 is rotated to a suitable position, so that the butterfly chair can be folded;

[0035] 2. By sliding the second slide post 311, the second slide post 311 can drive the second convex post 310 to slide, and at the same time slide the lifting post 303 to a suitable position, so that the second convex post 310 is engaged with the limiting hole 304 on the surface of the lifting post 303, and the height can be adjusted.

[0036] When the present technical solution needs to be folded, the threaded rod 312 is twisted to separate the threaded rod 312 from the lifting column 303, and the sliding column 209 is slid at the same time. The sliding column 209 drives the protruding column 208 to slide, so that the protruding column 208 is separated from the through hole 210 on the surface of the rotating block 204, and the rotating block 204 is rotated to a suitable position. At the same time, the sliding column 209 is loosened, and the spring 207 pushes the protruding column 208 to slide, so that the protruding column 208 is engaged with another through hole 210 on the surface of the rotating block 204. The butterfly chair can be folded for easy carrying. Since the wear-resistant pad 306 and the protective pad 306 are arranged on the bottom surface of the connecting plate 305 07, the friction between the connecting plate 305 and the ground is improved to avoid slipping. By sliding the sliding column 2 311, the sliding column 2 311 can drive the convex column 2 310 to slide, and at the same time slide the lifting column 303 to a suitable position, loosen the sliding column 2 311, and the spring 2 309 pushes the convex column 2 310 to slide, so that the convex column 2 310 is engaged with the limiting hole 304 on the surface of the lifting column 303, and the height of the base 1 can be adjusted. At the same time, due to the arrangement of the threaded rod 312 and the sleeve 313, the stability between the connecting plates 305 is improved, and the height of the lifting column 303 on the other side can be adjusted to be different from the lifting column 303, so as to adjust the angle of the base 1.
