One side of the mounting seat 522 is provided with a convex buckle 524, the upper end of the buckle 524 is made into a circular arc shape, the buckle 524 is matched with the buckle groove 414, when the support frame 5 is in a unfolding state, the buckle 524 enters into the buckle groove 414 to play a certain locking role on the support frame 5, so that the support frame 5 is kept in the unfolding state, the support frame 5 is prevented from suddenly sliding to be in a folding state in the using process, and the safety is improved.

The technical scheme is as follows: the frame 51 includes side bars 512 and upper and lower cross bars 513, 514 on both sides, the inner side of the lower cross bar 514 is concave and the outer side is convex, the lower cross bar 514 protrudes out of the plane where the two side bars 512 are located, the upper ends of the two side bars 512 are bent outwards, both ends of the upper cross bar 513 are respectively connected with the bent upper ends of the two side bars 512, the upper cross bar 513 also protrudes out of the plane where the two side bars 512 are located, and the upper cross bar 513 increases the stability of the support frame 5. When the support frame 5 is in a folded state, the two side rods 512 penetrate through the notch 415 and cling to the bottom of the decorative ring 4, a gap exists between the lower cross rod 514 and the flat plate 11, and the upper cross rod 513 and the lower cross rod 514 serve as standing legs to enable the bath barrel in a storage state to be placed stably. When the support frame 5 needs to be unfolded, the support frame 5 can be unfolded by pulling the lower cross rod 514 by hand due to the gap between the lower cross rod 514 and the flat plate 11, so that the operation is more convenient and humanized. The bottom of the bottom cross bar 514 is also provided with an anti-slip pad 8, and the anti-slip pad 8 prevents the support frame 5 from sliding in the unfolded state, thereby improving the safety.

The technical scheme is as follows: as shown in fig. 11, the U-shaped pull ring 7 includes a handle 72 and slide bars 71 located at two sides of the handle 72, two slide rails 61 are formed on the inner surface of the bottom decoration board 6, the two slide bars 71 are respectively located in the two slide rails 61, and when the folding bath tub is in a semi-folded state, the handle 72 or the two slide bars 71 are located on the support frame 5 after the U-shaped pull ring 7 is pulled out, so as to support the flat plate 11.

The technical scheme is as follows: the head of the sliding rod 71 is provided with a protrusion 711, and the sliding rail 61 is provided with a stop 612 for limiting the moving distance of the protrusion 711. The inner end of the sliding rail 61 is also provided with a bottom hole 611, the bottom hole 611 is provided with a positioning hook 62, the positioning hook 62 has a certain elasticity, and the bottom hole 611 provides a space for ejecting the positioning hook 62. As shown in fig. 5, one end of the positioning hook 62 is connected with the sliding rail 61 and is provided with a groove 622, the groove 622 is matched with the protrusion 711, the other end of the positioning hook 62 is provided with a bump 621, a gap exists between the bump 621 and the hole wall of the bottom hole 611, the end surface of the bump 621 near the center of the sliding rail 61 is provided with a sliding-in inclined surface 6211, as shown in fig. 6, the end surface of the protrusion 711 near the inner end of the sliding rail 61 is provided with a guiding-in inclined surface 7111.

When the invention is in a storage state or a bath barrel state, the U-shaped pull ring 7 is pushed into the bottom decorative plate 6 as much as possible, the protrusion 711 extrudes the positioning hook 62 under the action of two inclined planes of the protrusion 711 and the protrusion 621, the positioning hook 62 downwards flicks under the action of force, the protrusion 711 slides into the groove 622, the positioning hook 62 is reset, the protrusion 711 is locked by the protrusion 621, the protrusion 711 is prevented from retreating and sliding out, and the handle 72 is positioned at the end part of the bottom decorative plate 6; when the invention is in a semi-folded vertical bathtub state, the U-shaped pull ring 7 is pulled by force, the protrusion 711 presses the protruding block 621, the positioning hook 62 downwards flicks under the action of force, the protruding block 621 and the protrusion 711 are unlocked, the protrusion 711 is driven by force to be separated from the groove 622, the U-shaped pull ring 7 is gradually pulled out until the protrusion 711 is limited by the stop block 612, the handle 72 or the two side sliding rods 71 are positioned on the upper cross rod 513 at the moment, and the handle 72 or the two side sliding rods 71 support the bottom plate 1, so that the annular bathtub wall 3 is not unfolded under the action of gravity, and the bathtub state is maintained.

The technical scheme is as follows: in order to facilitate water drainage, drain holes are formed at two ends of the bottom plate 1, the drain holes are staggered in the bottom decorative plate 6, the bottom of the bottom plate 1 further comprises a drain plug 9 matched with the drain holes, as shown in fig. 12, for clearly showing the direction of reference numerals, no section line is drawn in fig. 12, the drain plug 9 comprises a plug seat 91 and a plug body 92, the plug seat 91 is composed of an upper elastic sheet 911, a lower elastic sheet 912 and an elastic wall 913 connecting the upper elastic sheet 911 and the lower elastic sheet 912 into a whole, the upper elastic sheet 911, the lower elastic sheet 912 and the elastic wall 913 are all annular, an annular groove 914 is formed between the upper elastic sheet 912 and the outer wall of the elastic wall 913, and the plug body 92 is in interference fit with the inner wall of the elastic wall 913 after being inserted into the plug seat 91.

After the plug seat 91 of the drain plug 9 is plugged into the drain hole at the bottom of the bath appliance, the upper surface and the lower surface of the drain hole and the edge thereof can be in three-surface contact seal with the annular groove 914, and then the plug body 92 is in interference fit with the inner wall of the elastic wall 913 after being inserted into the plug seat 91, and meanwhile, the elastic wall 913 is supported, so that the outer wall of the elastic wall 913 is in extrusion contact with the drain hole wall of the bath appliance, and the sealing performance is greatly improved. In addition, this structure can prevent the plug seat 91 mounted on the drain hole from falling off.

As shown in fig. 13, the plug seat 91 and the plug body 92 are integrally connected by the water plug belt 93, so that the plug body 92 is prevented from being lost.

The upper edge of the plug 92 is provided with a connecting ear 921, one end of the water plug belt 93 is connected with the upper elastic piece 911, and the other end is connected with the connecting ear 921. The function of the connecting ear 921 is to provide a portion that can easily grasp and apply force to the plug 92 when the plug 92 is pulled out of the plug holder 91. Meanwhile, after the plug body 92 is inserted into the plug seat 91, the connecting ear 921 is located above the plug body 92, that is, a visible part in normal use, so that the plug body can be designed into different shapes to play a role in beautifying the visual effect, for example, the connecting ear 921 is designed into a plum blossom shape in the embodiment, as shown in fig. 14.

The outer diameter of the upper portion of the plug 92 is larger than that of the lower portion, and the plug 92 with a large upper portion and a small lower portion is more convenient to be inserted into the plug seat 91.

The upper portion of the plug 92 is formed with a cylindrical recess 922. The plug 92 with the cylindrical recess 922 has a short injection molding cycle and a relatively flat product surface, and substantially eliminates shrinkage shadows.

In addition, the outer diameter of the upper elastic piece 911 is slightly smaller than the outer diameter of the lower elastic piece 912. This design makes the plug 92 easier to install because the plug 92 is typically fitted into the drain hole in the bottom of the bathing implement from below to above.

The foregoing describes in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the invention by one of ordinary skill in the art without undue burden. Therefore, all technical schemes which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the technical personnel in the field according to the conception of the invention are within the protection scope of the invention.
