[0032] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific implementation of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed for protection in the present invention.

[0033] Example 1

[0034] refer to Figure 1-4 and Fig. 9 The present embodiment provides a foldable bathtub, comprising a basin body 1, which can be switched between a folded state and an unfolded state. The basin body 1 comprises a basin bottom 11, a basin wall and a folding structure, wherein the basin bottom 11 and the basin wall are both made of a first plastic, wherein the folding structure is made of a second plastic, wherein the rigidity of the second plastic is less than that of the first plastic, and the second plastic has excellent toughness, so that the folding structure itself can be bent and deformed.

[0035] A bendable bottom flexible connection part 110 is provided at the periphery of the basin bottom 11. The basin wall is arranged at the top of the basin bottom 11, and the bottom periphery of the basin wall is connected to the bottom flexible connection part 110, so that the basin wall can rotate relative to the basin bottom 11. The basin wall includes a front wall surface 121, a rear wall surface 122 and two side wall surfaces 123, and the adjacent wall surfaces are connected by a bendable side wall flexible connection part 120, and the lower end of each side wall flexible connection part 120 is connected to the bottom flexible connection part 110, so that the adjacent wall surfaces can rotate relative to each other. In this embodiment, the bottom flexible connection part 110 and the side wall flexible connection part 120 are both made of the second plastic, and the bottom flexible connection part 110 is respectively integrally formed with the basin bottom 11, the basin wall and the lower end of the side wall flexible connection part 12, and the side wall flexible connection part 120 is integrally formed with the adjacent wall surface.

[0036] The folding structure includes two first folding portions 13 and a second folding portion 14. The two first folding portions 13 are respectively arranged on the two side wall surfaces 123. In this embodiment, the first folding portion 13 is integrally formed with the corresponding side wall surface 123, and the lower end of the first folding portion 13 is integrally formed with the bottom flexible connection portion 110 and / or the side wall flexible connection portion 120 arranged near it. The second folding portion 14 is transversely arranged in the middle of the front wall surface 121, and its left and right ends extend backward to the two side wall surfaces 123 and are connected to the two first folding portions 13. In this embodiment, the second folding portion 14 is respectively integrally formed with the front wall surface 121, the two side wall surfaces 123 and the two side wall flexible connection portions 120 arranged near it. Thus, the front wall surface 121 can be folded toward the inside of the basin body 1 relative to the second folding portion 14, that is, the front wall surface 121 can be folded backward, and the side wall surface 123 can be folded inward and backward or outward and backward relative to the first folding portion 13 and the second folding portion 14. This embodiment takes the folding of the side wall surface 123 inward and backward as an example.

[0037] When the basin body 1 is in a folded state, the front wall surface 121 is folded inwards, the two side walls 123 are folded inwards and backwards, and the rear wall surface 122 is driven by the two side walls 123 to rotate and close toward the front wall surface 121, so that the folded front wall surface 121 is sandwiched between the rear wall surface 122 and the basin bottom 11, and the two folded side walls 123 are also sandwiched between the rear wall surface 122 and the basin bottom 11, which is convenient for folding, storage and carrying. At this time, the dimensions of the folded basin body 1 in the left and right and front and back directions are close to the dimensions of the basin bottom 11 or the rear side wall 122, but the thickness in the height direction is larger. In addition, compared with the existing foldable bathtubs whose bottom can be lifted up or protruded downwards, the basin bottom 11 of the patent is flat, which ensures the stability of the support of the bottom of the bathtub and prevents the problem of shaking or being unsuitable for lifting the head upwards due to the unstable folding frame structure at the bottom.

[0038] It is particularly noted that when the side wall 123 is designed to be foldable outward and backward, when the basin body 1 is in a folded state, the folded front wall 121 is directly clamped between the rear wall 122 and the basin bottom 11, and the folded front wall 121 protrudes outside the rear wall 122 and the basin bottom 11. At this time, the folded basin body 1 is thinner in the height direction, but longer in the left and right direction.

[0039] refer to Figure 1-3 Further, the second folding portion 14 includes a bendable first front flexible connection portion 141 and two bendable side flexible connection portions 142, the first front flexible connection portion 141 is laterally arranged in the middle of the front wall surface 121, and the left and right ends of the first front flexible connection portion 141 are respectively connected to the two side wall flexible connection portions 120 arranged close thereto, at this time, the front wall surface 121 is separated into an upper front wall surface and a lower front wall surface by the first front flexible connection portion 141, and the upper front wall surface and the lower front wall surface can be folded close to each other or unfolded away from each other relative to the first front flexible connection portion 141.

[0040] The two side flexible connection parts 142 are respectively arranged horizontally or obliquely on the front ends of the two side wall surfaces 123, and the front ends of the two side flexible connection parts 142 are respectively connected to the left and right ends of the first front flexible connection part 141 through the two side wall flexible connection parts 120, and the rear ends of the two side flexible connection parts 142 are respectively connected to the two first folding parts 13. At this time, the front end of the side wall surface 123 is divided into a front upper part of the side wall surface and a front lower part of the side wall surface by the side flexible connection part 142. The front upper part of the side wall surface and the front lower part of the side wall surface can be folded close to or unfolded away from the side flexible connection part 142. In this way, after the side wall surface 123 is folded inward or outward with respect to the first folding part 13, it can be folded backward with respect to the second folding part 14, thereby driving the rear wall surface 122 to rotate and fold toward the front wall surface 121.

[0041] In other embodiments, the second folding portion 14 may also include a bendable second front flexible connection portion, and at least one second front flexible connection portion located on the front wall surface 121 is provided above and / or below the first front flexible connection portion 141, so that the front wall surface 121 can be folded relative to the second front flexible connection portion, thereby making the size of the folded front wall surface 121 smaller.

[0042] refer to Figure 1-3, further, the first folding portion 13 is in an inverted "Y" shape, which divides the side wall surface 123 into a front side wall portion, a rear side wall portion and a lower side wall portion, wherein the front side wall portion constitutes the front end of the side wall surface 123, and the rear side wall portion constitutes the rear end of the side wall surface 123. Specifically, the first folding portion 13 includes a bendable upper flexible connection portion 131 and two bendable lower flexible connection portions 132, the upper flexible connection portion 131 is vertically arranged at the middle of the upper end of the side wall surface 123; the two lower flexible connection portions 132 form an inverted "V" shape, and are obliquely arranged at the lower end of the side wall surface 123, and the upper ends of the two lower flexible connection portions 132 are connected to the lower end of the upper flexible connection portion 131, and the lower ends are connected to the side of the bottom flexible connection portion 110 and / or the lower end of the side wall flexible connection portion 120 arranged close thereto. The rear end of the side flexible connection portion 142 is connected to the corresponding upper flexible connection portion 131 and / or the corresponding lower flexible connection portion 132 .

[0043] refer to Figure 2-3 Furthermore, a gripping portion 1231 is provided at the upper ends of the two side walls 123. The gripping portion 1231 is a handle hole that passes through the upper end of the first folding portion 13, so that the user can carry or move the unfolded bathtub through the gripping portion 1231. Of course, the gripping portion can also be provided on the upper end of the front wall 121 and the upper end of the rear wall 122.

[0044] Furthermore, first flanges 1211 extending outward are respectively provided at the upper ends of the front wall 121 and the rear wall 122, and second flanges 1232 extending outward are respectively provided at the upper ends of the two side walls 123, so as to strengthen the wall strength of the basin and prevent scratches on the user. In addition, oppositely arranged avoidance portions 1212 are provided on the first flanges 1211 of the front wall 121 and the first flanges 1211 of the rear wall 122, and the avoidance portions 1212 are notches and can be used as handles or grips. In this way, when the bathtub is in a folded state, the distance between two adjacent avoidance portions 1212 is smaller than the distance between the first flanges 1211 of the front wall 121 and the first flanges 1211 of the rear wall 122, making it more convenient for the user to take the folded bathtub.

[0045] Example 2

[0046] refer to Figure 1-3 The difference between this embodiment and embodiment 1 is that the foldable bathtub also includes a basin lock assembly 3, and the upper end of the rear wall 122 and the front end of the basin bottom 11 are locked or unlocked through the basin lock assembly 3, or the upper end of the rear wall 122 and the front edge of the bottom flexible connecting part 110 are locked or unlocked through the basin lock assembly 3. In this way, the bathtub can be stably and reliably maintained in a folded state, avoiding automatic dispersal or unfolding during transportation or carrying, and is more convenient to carry and store.

[0047] Furthermore, the basin lock assembly 3 includes a lock buckle 31 and a lock tongue 32. The lock buckle 31 is arranged at the upper end of the rear wall surface 122 and is located outside the basin wall. In this embodiment, a lock pin extending downward is integrally formed at the outer edge of the first flange 1211 of the rear wall surface 122, and the lock pin constitutes the lock buckle 31. The fixed end of the lock tongue 32 is arranged on the front end of the basin bottom 11 or the front edge of the bottom flexible connection part 110, and the free end is used to cooperate with the lock buckle 31. Therefore, through the cooperation and engagement of the lock buckle 31 and the lock tongue 32, the folded bathtub can be prevented from automatically spreading or unfolding, which is more convenient to carry or store.

[0048] The locking tongue 32 can be a bendable rubber strip, plastic or shrapnel, or a draw cord. In the present embodiment, the locking tongue 32 is preferably plastic, which is integrally formed with the bottom flexible connecting portion 110, and of course, can also be integrally formed with the front end of the basin bottom 11.

[0049] Example 3

[0050] refer to Figure 1-9 The difference between this embodiment and the first or second embodiment is that the foldable bathtub further comprises a locking member 4, and the locking member 4 is provided with a slot 401 opening downward, and the slot 401 is suitable for accommodating the upper end of the side wall surface 123 or the upper end of the first folding portion 13. During installation, the locking member 4 is detachably or movably clamped on the upper end of the first folding portion 13 and the outer upper end of the side wall surface 123. In this embodiment, the locking member 4 is clamped on the upper end of the first folding portion 13 and the outer upper end of the side wall surface 123 movably. The locking member 4 can move forward and backward along the first folding portion 13 and the upper end of the side wall surface 123, and switch between a locked position and an unlocked position.

[0051] refer to Figure 1-4 When the locking member 4 is in the locked position, the locking groove 401 of the locking member 4 is engaged with the upper end of the first folding portion 13 and the upper end of the side wall surface 123 respectively. At this time, the locking member 4 can prevent the side wall surface 123 from folding inward or outward relative to the first folding portion 13, so that the side wall surface 123 is stably and reliably maintained in the unfolded state, thereby maintaining the bathtub in the unfolded state, avoiding the abnormal phenomenon of automatic folding during use. On the contrary, refer to Fig. 9 When the locking piece 4 is in the unlocked position, or when the locking piece 4 is detached from the basin body 1, the clamping relationship between the locking piece 4 and the upper end of the first folding portion 13 is released. At this time, the side wall surface 123 can be automatically folded inward or outward relative to the first folding portion 13, so that the bathtub can be folded and folded.

[0052] refer to Figure 4-6Furthermore, a receiving groove 402 is provided inside the upper end of the locking member 4, and the receiving groove 402 is connected with the locking groove 401 and together forms an inverted "U" shape. A second flange 1232 extending outward is integrally formed at the upper end of the side wall surface 123 and / or the upper end of the first folding portion 13, and the second flange 1232 is inserted into the receiving groove 402 and is used to hook the inner groove wall of the receiving groove 402, so that the locking member 4 is stably and reliably installed at least at the upper end of the side wall surface 123, and prevents the locking member 4 from automatically detaching from the bathtub 1.

[0053] refer to Figure 5-8 In this embodiment, the locking member 4 is designed in a split form, including a jacket 41 and a bracket 42, and the jacket 41 is provided with a concave cavity 411 opening downward. The upper end of the bracket 42 is inserted into the concave cavity 411 and is detachably connected to the jacket 41, and the upper end of the bracket 42 divides the concave cavity 411 into a connected card slot 401 and a receiving slot 402. In other embodiments, the locking member 4 can be designed in an integrated form, that is, the jacket 41 and the bracket 42 are designed to be integrally formed.

[0054] A lower boss 412 extending inward is integrally formed at the lower end of the outer cavity wall of the concave cavity 411. Correspondingly, a mounting groove 421 opening toward the lower boss 412 is provided at a position corresponding to the lower boss 412 in the middle of the bracket 42. During installation, the upper end of the bracket 42 is inserted into the concave cavity 411 and is detachably connected to the jacket 41. The lower boss 412 is embedded in the mounting groove 421 and is detachably connected to the bracket 42 via a connecting member (such as a screw). Specifically, two vertically arranged mounting holes 422 are spaced apart at the lower end of the bracket 42. The upper ends of the two mounting holes 422 are respectively connected to the mounting groove 421. A fixing hole 4121 is provided at a position corresponding to the mounting hole 422 of the lower boss 412. During installation, the connecting member passes through the mounting hole 422 and the fixing hole 4121 from bottom to top and is tightly connected to the hole wall of the fixing hole 4121.

[0055] In addition, an upper boss 413 extending inward is integrally formed in the middle of the outer cavity wall of the cavity 411, and the upper boss 413 is located above the lower boss and the two are arranged at an interval. A positioning groove 423 is provided at the upper end of the bracket 42 at a position corresponding to the upper boss 413, and the free end of the upper boss 413 is inserted into the positioning groove 413. In this way, the bracket 42 is quickly positioned on the jacket 41 through the matching and plugging of the upper boss 413 and the matching and plugging of the lower boss 412 and the mounting groove 421, so that the connection between the bracket 42 and the jacket 41 is more firm and reliable.
