[0002] With the improvement of people's living standards, the requirements for bathroom equipment in the family are also getting higher and higher. The bathtub is a very commonly used bathroom equipment. However, the bathroom space in general families is limited. The existing bathtubs are usually made of ceramic and have a rigid structure, occupying a large space. If the bathroom area is too small, it will be difficult to install a bathtub, resulting in many families being unable to use a bathtub. Especially under the influence of the current rising housing prices, most just-needed people purchase houses with a relatively small area. The space in the bathroom of the family is sometimes small and generally not suitable for installing a large bathtub. However, the just-needed people often have a great work pressure and hope to have a bathtub for bathing to relieve fatigue after working hard. There is a problem that the bathroom space is not enough to meet the requirement of taking a bath.

[0003] At present, the folding bathtubs existing on the market and those recorded in relevant literatures have various structural forms, but most of them have the problem of troublesome unfolding and folding. It is very difficult to achieve one-step unfolding and folding operations. Most of the folding bathtubs recorded in relevant literatures cannot be effectively implemented due to poor practicality in design. The various folding bathtubs sold online generally have their defects and a large number of negative reviews. Summary of the Invention

[0044] The skeleton part includes the rear side frame 1 and the front side frame 2, wherein the rear side frame 1 is the fixed part and the front side frame 2 is the movable part. Figure 1 It can be seen that both the rear side frame 1 and the front side frame 2 include U-shaped rods, and upper connecting rods are connected to the upper ends of the U-shaped rods through fixing sleeves.

[0045] On the left and right sides of the upper ends of the rear side frame 1 and the front side frame 2, rotatable hinge parts are respectively installed. Refer to Figure 6 As shown, each hinge part is respectively fixedly connected with a swing rod 4. The ends of the pair of swing rods 4 on the left are respectively hinged in the left connecting sleeve through a rotating shaft, and the ends of the pair of swing rods 4 on the right are respectively hinged in the right connecting sleeve through a rotating shaft.

[0046] In this embodiment, a vertical fixed sleeve tube 7 is further arranged below the connecting sleeve, and a column 3 is sleeved in the vertical fixed sleeve tube 7.

[0047] The rear side frame 1 is fixed to the wall through a fixing component, and the fixing component can be as Figure 1The shown punch-free fixing component includes a wall fixing patch 10, on which a fixing bolt 11 is vertically connected. At the same time, fixing holes are provided on the rear side frame 1, and the fixing bolt 11 passes through the fixing holes and is locked by nuts. A support sleeve 12 can be sleeved on the fixing bolt 11 to adjust the distance between the rear side frame 1 and the wall surface. The fixing component can also fix the rear side frame 1 by drilling holes in the wall and installing expansion wires. Thus, the rear side frame 1 can rely on the support of the wall to keep the overall folding skeleton stable and with high strength. The flipping part can cooperate with the fixing part, so that in the folded state, the flipping part can also fit against a single-sided wall (usually set below the shower for easy use), so as to compress the bathtub frame as much as possible and keep the bathtub hidden in the wall corner position after being folded.

[0048] See Figure 4 As shown, the bathtub cloth layer 23 is a bagged structure containing side walls and a bottom surface all around, and the bagged structure is provided with a cloth layer upper sleeve at least at the upper peripheral edge. See Figure 21 and Figure 22 As shown, the bathtub cloth layer 23 is a single-layer waterproof cloth layer, or a double-layer waterproof cloth layer, or sequentially includes a nano cloth layer, a waterproof cloth layer, a heat preservation cotton layer, a waterproof cloth layer and a nano cloth layer from the inside out. See Figure 5 As shown, each cloth layer upper sleeve is sleeved on the connecting rods on the upper sides of the rear side frame 1 and the front side frame 2 and on each swing rod 4. The skeleton structure of this embodiment can adopt a limiting structure to maintain the stability of the skeleton when unfolding or folding. The limiting structure can also not be adopted, in which case the whole skeleton can be appropriately deformed without affecting the overall support strength. The appropriately deformed skeleton can keep the folding bathtub bypass necessary obstacles.

[0049] During the unfolding process of the front side frame 2 relative to the rear side frame 1, the swing rods 4 on both sides are stretched, but each swing rod 4 is provided with a positioning mechanism to prevent excessive flipping. After water is added to the folding bathtub, the bathtub cloth layer 23 is pressed by the water and stretches outwards, forming a positive and negative reaction force with the positioning mechanism of the swing rod 4. Coupled with the support of the rear side frame 1 and the front side frame 2, the whole folding bathtub forms a stable support structure. Coupled with the support and restraint of the wall, the overall stability of the folding bathtub is very strong. This solution can achieve one-step unfolding or folding, with simple and convenient operation. Especially, it can realize bathing by unfolding the bathtub in one step while taking a shower, that is, having the bathing condition during the shower, and this way is very easy to be accepted and used by the majority of consumers.

A vertical column 3 is fixedly connected between the upper and lower connecting sleeves on the left. Moreover, a vertical column 3 can also be fixedly connected between the upper and lower connecting sleeves on the right.

[0054] In this embodiment, in addition to the U-shaped structure of Example 1, the rear side frame 1 and the front side frame 2 can also be a combined frame formed by fixedly combining upper and lower connecting rods and each vertical column 3. The structural scheme of this embodiment has very high strength.

[0055] Example 5: On the basis of Example 1, referring to Figures 10 - 17 the shown skeleton structure, both the rear side frame 1 and the front side frame 2 are n-shaped rods.

[0056] Movable sleeves are installed at the ends of the swing rod 4, and the movable sleeves at the ends of adjacent pairs of swing rods 4 are meshed with each other through gears.

[0057] A fixed retaining sleeve fixed on the rear side frame 1 or the front side frame 2 is arranged below the hinge part, and a locking pin is arranged on the fixed retaining sleeve.

[0058] In addition, as Figure 15 and Figure 16 shown, a vertical fixed retaining platform 21 is arranged on the upper side edge of the fixed retaining sleeve, and a vertical movable retaining platform 20 is arranged on the lower side edge of the hinge part. The fixed retaining platform 21 and the movable retaining platform 20 can be matched and docked.

[0059] The bathtub cloth layer 23 in this embodiment can be folded in two ways. Refer to Figure 12 , Figure 13 and Figure 21 shown, which is the first folding method. Refer to Figure 23 and Figure 24 shown, which is the second folding method. Among them, when the first folding method is adopted, it is not suitable to use the column 3 to support under the connecting sleeve at the end of the swing rod 4. However, when the second folding method is adopted, the column 3 can be used to support under the connecting sleeve at the end of the swing rod 4.

[0060] Embodiment 6: On the basis of Embodiment 5, combined with Figure 18 shown, a pair of swing rods 4 on the left and right sides are respectively provided with an enhanced structure of two pairs of swing rods 4. In this case, either the method of using the column 3 to support the connecting sleeve or the column 3 can be omitted. That is, the first folding method or the second folding method can be adopted.
