Description

Technical Field

[0001] The utility model relates to the field of foldable bathtubs, in particular to a downward-pressing foldable bathtub. Background Art

[0002] A bathtub is a container for people to take a bath. After pouring hot water into it, people can soak in the water and take a bath. However, the existing bathtubs are usually large in size and take up a large space when not in use. Therefore, the bathtubs on the market are composed of several support frames and cloth covers. When the bathtub is not in use, the vertical support frames can be folded to make the bathtub smaller. However, during the folding process, since the connectors connecting the support frames are usually integrated with the support frames or fixed with screws, the folding process is relatively laborious, the folding effect is not particularly good, and the bathtub occupies a large space after folding, which is not conducive to storage.

[0003] Folding bathtubs that use splicing are not only difficult to assemble, but also very difficult to disassemble. They require strong wrist strength to break the interference fit of the connecting structure, which is very unfriendly to the elderly, children, and female users.

[0004] Therefore, there is a need for a foldable bathtub that can be folded more easily, has a good folding effect, and occupies a smaller space after folding. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a push-down foldable bathtub. The foldable bathtub has the advantages of simple folding process, can be assembled and delivered, and can be unfolded and used without user installation. It has the advantages of fast activation / storage, simple activation / storage steps, and small space occupation.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] A downward-pressing foldable bathtub comprises a bathtub body, wherein the bathtub body is provided with a soft covering layer and a bathtub support, wherein the soft covering layer is connected to the bathtub support;

[0008] The barrel-forming support member can support the soft covering layer to form a barrel-shaped structure in an unfolded state, which is a use state;

[0009] When the barrel support member is transformed from an unfolded state to a folded state, the soft covering layer can be folded together, so that the soft covering layer is transformed from a barrel-like structure to a block structure. This state is a storage state and occupies little space.

[0010] The barrel support is composed of a shaping frame and a supporting frame, and the shaping frame and the supporting frame are connected by a connector. The shaping frame and the supporting frame are both formed by splicing support rods and connectors. The connector can form the shaping frame and the supporting frame and also serves as a connecting member of the two, achieving a multi-functional effect.

[0011] The connector can be rotated on the shaping frame, that is, the support frame can change the angle between it and the shaping frame through the connector, so as to achieve flipping, which is convenient and simple to store. A limiter is also provided between the connector and the support rod, which can prevent the connector from being separated from the support rod during rotation or use. The bathtub body can be folded / activated repeatedly without being easily damaged.

[0012] The connector is divided into a fixed connector and a folding connector. The fixed connector is used to connect the support rod at the position where no displacement occurs to further improve the tightness. The folding connector is used at the position where the folding occurs to ensure the tightness while allowing the barrel support to be smoothly turned over for easy storage by the user.

[0013] At least one pair of folding joints is provided at the connection between the shaping frame and the supporting frame, so that the shaping frame can be folded so that the supporting frame can fit with the shaping frame, and the rest are fixed joints;

[0014] The support frame is provided with inclined support rods, forming a triangular structure in the support frame. Utilizing the stability principle of the triangle, a single support rod is directed to only one corner, and the length of the support rod determines the opening (i.e., size) of the corner. This structural characteristic enables the support frame to maintain its shape and size when subjected to force, thereby being stable, firm, and pressure-resistant.

[0015] The support frame can also be connected to the support rod through a folding joint and a fixed joint to form a support frame with a folding effect, that is, the shaping frame and the support frame can be folded, further reducing the cross-section of the bathtub body after folding.

[0016] In one embodiment, an inflatable ring is provided on the top of the soft covering layer for the user to lean on. The outermost layer of the soft covering layer is a shaping layer, which has an anti-stretching effect and prevents the bathtub body from deforming. The innermost layer in contact with the human body is a waterproof layer. An insulation layer is sandwiched between the shaping layer and the waterproof layer to delay temperature loss. The soft covering layer protrudes from the shaping frame. The protruding part can be turned outward to cover the shaping frame to form a sleeve that can be inserted into the shaping frame, forming a stable connection, which is convenient for deformation together with the shaping frame. A tight rod layer for the side support rods to penetrate is also provided on the shaping layer. The side support rods cooperate with the support frame to keep the side walls of the bathtub body in an expanded state and are not easy to deform. Insertion holes are provided at the upper and lower ends of the tight rod layer. The side support rods are connected to the shaping frame after penetrating the tight rod layer. The side support rods can also rotate around the shaping frame, that is, the side support rods can be folded and stored.

[0017] In one embodiment, the limiting member consists of a boss and a limiting groove, the boss is arranged on the support rod, and a spring is provided at the bottom of the boss, which can make the boss protrude from the support rod when not subject to external force and can be stuck in the limiting groove, and the limiting groove is divided into a hole groove and an arc groove, the hole groove can tighten the support rod so that it cannot be offset, and the arc groove can limit the support rod from being separated from the connecting head. At the same time, the arc groove is a space to avoid the boss when the connecting head and the support rod rotate, and the side wall of the limiting groove is inclined outward, and bosses are provided at both ends of the support rod, and the support rod must have a boss at one end placed in the hole groove.

[0018] In one embodiment, the folding joint is composed of two connecting rod seats connected by a folding piece, and the folding effect of the folding joint is achieved by the folding piece. The connecting rod seat is provided with at least one limiting groove and a rod entry port, and the folding piece is provided with an insert and a clamping piece. The insert and the clamping piece are provided with connecting holes located on the same straight line. The insert can be inserted into the clamping piece. The insert is arranged on one of the connecting rod seats, and the clamping piece is arranged on the other connecting rod seat. Bolts can be inserted into the connecting holes to lock the insert and the clamping piece so that the two can only be folded and cannot move longitudinally.

[0019] In one embodiment, the fixed joint is divided into a T-joint, a butterfly joint and an angled joint. Different parts are connected using fixed joints of different shapes to ensure the stability of the connection while reducing the space occupied by the fixed joint. The above three joints are all provided with at least two rod entry openings and the same number of limit slots. The limit slots can be selected as hole slots / arc-shaped slots according to actual needs. The T-joint and the butterfly joint can be used on the shaping frame to form the shaping frame. The rod entry openings at the lower ends of the T-joint and the butterfly joint are used to connect the side support rods or the support frame. The angle between the rod entry openings provided in the angled joint does not exceed 30°. The angled joint is used to connect the support rods on the lower side of the support frame and the inclined support rods in the middle of the support frame.

[0020] In one embodiment, the folding joint is divided into a straight-line flip head, a T-shaped flip head and a disc-shaped flip head. The appropriate folding joint is selected according to the number and structure of the linked support rods to ensure the reasonable occurrence of folding, so that the user can fold / activate quickly. The straight-line flip head is provided with two rod entry openings located on the same straight line, which support the two support rods to fold in a straight line state. The T-shaped flip head has the same shape as the T-joint, and the folding part is offset to one side to avoid the rod entry opening located below to prevent the support rod below from detaching when folding occurs. The T-shaped flip head supports a right-angle structure composed of two vertical support rods and another support rod connected to the T-shaped flip head. The support rod is folded, that is, the horizontal support rod on one side of the T-shaped structure is folded. The disc-shaped flip head has the same appearance as the butterfly joint, and the folding part is arranged in the middle of the disc-shaped flip head. One side of the disc-shaped flip head can be connected to a horizontal support rod and an inclined support rod. The two support rods form a pointed structure, and the disc-shaped flip head can form two mirrored pointed structures and flip them along the symmetry axis. The horizontal support rod is located on the shaping frame, and the inclined support rod is located on the support frame, so that the shaping frame can be folded and the triangular structure of the support frame can be accommodated at the same time. A reinforcement key is provided between the two connecting rod seats of the straight flip head, the T-shaped flip head and the disc-shaped flip head.

[0021] In one embodiment, the shaping frame is composed of arc-shaped rods and straight rods inserted into connecting heads, and is in the shape of a capsule with a hollow middle portion to form the mouth of the bathtub body. There are two arc-shaped rods, which are arranged on both sides of the straight rod. The support frame is composed of multiple straight rods inserted into connecting heads.

[0075] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0076] Example 1

[0077] See also Figure 1-7 A downward-pressing foldable bathtub comprises a bathtub body 1, wherein the bathtub body 1 is provided with a soft covering layer 2 and a bathtub support, wherein the soft covering layer 2 is connected to the bathtub support in a linkage manner;

[0078] The barrel-forming support member can support the soft covering layer 2 to form a barrel-shaped structure in the unfolded state;

[0079] When the tub support member is transformed from an unfolded state to a folded state, the soft covering layer 2 can be folded together, so that the soft covering layer 2 is transformed from a tub-like structure to a block-like structure. According to actual needs, the tub support member can be folded at least once, and the area occupied by the bathtub body can be reduced by half after each folding.

[0080] The barrel support is composed of a shaping frame 3 and a supporting frame 4, both of which are foldable. The shaping frame 3 and the supporting frame 4 are connected by a connector 5. The shaping frame 3 and the supporting frame 4 are both formed by splicing support rods and connectors 5, that is, the connector connecting the two is multi-purpose.

[0081] The connecting head 5 can be rotated on the shaping frame 3, that is, the supporting frame 4 can change the angle between it and the shaping frame 3 through the connecting head 5 to achieve a flipping effect. When flipping, the supporting frame 4 flips inward, and both sides cannot flip at the same time. After the flipping is completed, the supporting frame 4 on one side is located between the angle formed by the supporting frame 4 on the other side and the shaping frame 3, and is clamped by the two. The side wall of the bathtub body 1 will fit with the bottom wall of the bathtub body 1 as the supporting frame 4 flips, and the other side supporting frame 4 is pulled inward by the bottom wall to tilt inward, that is, only one side wall of the bathtub body 1 needs to be flipped inward to release the use state of the bathtub body 1 and enter the storage state. A limiter is also provided between the connecting head 5 and the support rod, and the limiter can prevent the connecting head 5 from being separated from the support rod during rotation or movement. At the same time, the limiter can also limit the angle at which the connecting head 5 can rotate.

[0082] The connector 5 is divided into a fixed connector and a folding connector. According to actual needs, the assembly scheme can be adjusted to achieve different folding schemes;

[0083] At least one pair of folding joints is provided at the connection between the shaping frame 3 and the supporting frame 4, so that the shaping frame can be folded, and the rest are fixed joints. That is, after the supporting frame 4 is flipped over, the bathtub body 1 is transformed from the use state to the storage state. The flat bathtub body 1 can be folded once more through the folding joints, so that the bathtub body 1 can be folded once more in the storage state, further reducing the area of the bathtub body 1 in the storage state.

[0084] The support frame 4 is provided with an inclined support rod, forming a triangular structure in the support frame 4. When in use, the triangular structure can firmly support the crossbar in the middle of the shaping frame 3, while maintaining the stability of the bathtub body 1 in use, and can also provide an area for the user to place his arms, thereby improving comfort;

[0085] Among them, the support frame 4 can also be connected to the support rod combination through a folding joint and a fixed joint to form a support frame 4 with a folding effect, that is, the support frame 4 can be folded together with the shaping frame 3, and the folding directions of the two are unified, and the folding of the two parts can be completed by folding once.

[0086] like Figures 2 to 6 As shown, an inflatable ring 6 is provided at the top of the soft bag 2, and the inflatable ring is provided with an inflation and deflation valve. The outermost layer of the soft bag 2 is a shaping layer 7, and the innermost layer in contact with the human body is a waterproof layer 9. An insulation layer 8 is sandwiched between the shaping layer 7 and the waterproof layer 9. The soft bag 2 protrudes from the shaping frame 3, and the protruding part can be turned outward to cover the shaping frame 3 to form a sleeve 10 that can be inserted into the shaping frame 3. A tight rod layer 12 for the side support rod 11 to penetrate is also provided on the shaping layer 7. Insertion holes are provided at the upper and lower ends of the tight rod layer 12. The side support rod 11 penetrates the tight rod layer 12. The rod layer 12 is connected to the shaping frame 3. When in use, the shaping layer 7 can offset the expansion force of the water pressure and the human body on the bathtub body 1. The soft layer 2 is connected to the bathtub support through the sleeve 10, so that the bathtub support can carry the soft layer 2 for folding or unfolding. In use, the sleeve 10 can ensure that the soft layer 2 is firmly connected to the bathtub support and transfer the pressure to the bathtub support. The tight rod layer 12 can cover the side support rod 11, so that the side support rod uses the connection between the ground and the shaping frame 3 as the support point, tightens the side wall where the tight rod layer 12 is located, and prevents the bathtub body 1 from deformation.

[0087] like Figures 8 to 11 When the support rod is in the state of being moved, the spring 13 is provided at the bottom of the support rod, and the spring 13 is provided at the bottom of the support rod, and the spring 13 can make the support rod 13 protrude from the support rod when not subjected to external force. When installing / disassembling, the support rod 13 needs to be pressed into the support rod to enter / disengage the limit groove. The installation / disassembly steps are special, which effectively prevents accidental touch. The limit groove is provided with a hole groove 14 and an arc-shaped groove 15. The hole groove 14 can fasten the support rod so that it cannot deviate. The arc-shaped groove 15 can limit the support rod from being separated from the connector 5. At the same time, when the connector 5 and the support rod rotate, the arc-shaped groove 15 is a space to avoid the protrusion 13, and the side wall of the limit groove is inclined outward. The inclined space makes it easier for the user to press the protrusion 13 when disassembling. The protrusion 13 is provided at the upper and lower ends of the support rod, and the spring is provided in the support rod. When one end of the support rod reaches the arc-shaped groove 15, the other end should be placed in the connector 5 provided with the hole groove 14.

[0088] like Figures 12 to 14As shown; the folding joint is composed of two connecting rod seats 16 connected by a folding piece, and the connecting rod seat 16 is provided with at least one limit groove and a rod entrance 17, so that the support rods installed on different sides of the same folding joint can be flipped relative to each other, and the folding piece is provided with an insert 18 and a clamping piece 19, and the insert 18 and the clamping piece 19 are provided with connecting holes 20 located on the same straight line, and the insert 18 can be placed in the clamping piece 19, and the insert 18 is arranged on one of the connecting rod seats 16, and the clamping piece 19 is arranged on the other connecting rod seat 16. During installation, the insert 18 is placed in the clamping piece 19, and the connecting holes 20 provided on the two are located in the same straight line. The connection of the two connecting rod seats 16 can be achieved by locking the bolts. When folding occurs, the two connecting rod seats 16 are folded about the axial center line of the connecting hole 20.

[0089] like Figure 15 As shown; the fixed joints are divided into T-joints 21, butterfly joints 22 and angled joints 23. All of the above three are provided with at least two rod entry openings 17 and the same number of limit slots. The T-joints 21 and butterfly joints 22 can be used on the shaping frame 3 to form the shaping frame 3. The rod entry openings 17 provided at the lower ends of the T-joints 21 and butterfly joints 22 are used to connect the side support rods 11 or the support frame 4. The angle between the rod entry openings 17 provided in the angled joints 23 does not exceed 30°. There are two types of T-joints 21;

[0090] Among them: the upper end of the T-joint 21 is straight and is used to connect to the support frame 4. The support frame 4 needs to be folded. In order to ensure the stability of the support frame 4, the folding of the support frame 4 is actually the rotation of the T-joint 21 on the shaping frame 3. Therefore, the limiting grooves behind the rod entrances 17 on the left and right sides of the upper end of the T-joint 21 are arc-shaped grooves 15, and the limiting grooves at the bottom for connecting to the support frame 4 are hole grooves 14;

[0091] The arc-shaped upper end of the T-joint 21 is provided at the front and rear ends of the shaping frame 3 for connecting the side support rods 11. To further stabilize the side support rods 11, the bottom limiting groove of the arc-shaped T-joint 21 is a hole groove 14. To accommodate the side support rods, the two side grooves of the arc-shaped T-joint 21 are arc-shaped grooves 15.

[0092] When the butterfly joint 22 is arranged in the middle of the shaping frame 3, it is rotatable. Therefore, the limiting groove at the upper end of the butterfly joint 22 is an arc-shaped groove 15. The lower end of the butterfly joint 22 is connected to the inclined support rod forming the triangular structure. To ensure the stability of the triangular structure, the limiting groove at the lower end of the butterfly joint 22 is a hole groove 14.

[0093] The angled joint 23 is provided at the bottom of the support frame 4 . To stabilize the triangular structure formed by the entire support frame 4 , all the limiting grooves on the angled joint 23 are hole grooves 14 .

[0094] like Figure 16 As shown; the folding joint is divided into a straight-shaped flip head 24, a T-shaped flip head 25 and a disc-shaped flip head 26;

[0095] The inline turning head 24 is provided with two rod inlets 17 located in the same straight line. The inline turning head 24 is used to turn over the two support rods arranged in an inline manner, and cooperates with the dish-shaped turning head 26 to enable the support frame 4 to have a folding effect. The inline turning head 24 is provided at the bottom of the support rod. For the stability of the support frame 4, the limiting grooves provided on both sides of the inline turning head 24 are both hole grooves 14;

[0096] The T-shaped turning head 25 has the same appearance as the T-shaped joint 21, and the position of the turning piece is offset to one side to avoid the rod inlet 17 located below. Specifically, the T-shaped joint 21 is composed of two connecting rod seats 16;

[0097] One of the connecting rod seats 16 is composed of the bottom rod entrance 17 and the side rod entrance 17 of the T-joint 21, specifically an integrally formed right-angle elbow structure. The rod entrance 17 at the lower end is used to connect to the support frame 4, so the limiting groove provided is a hole groove 14. The rod entrance 17 at the upper end is connected to the shaping frame 3, and for rotation, the limiting groove provided is an arc-shaped groove 15. In order to reduce weight and space occupied, the connecting rod seat 16 described in this paragraph is provided with an insert 18;

[0098] The other connecting rod seat 16 is provided with only one side rod entrance 17 and is connected to the forming frame 3. To facilitate rotation, the limiting groove is an arc-shaped groove 15. Due to the relatively simple structure, a clamping member 19 is provided to enhance the counterweight and structural strength of the connecting rod seat 16 described in this paragraph.

[0099] The dish-shaped turning head 26 has the same appearance as the butterfly joint 22, and the folding piece is provided in the middle of the dish-shaped turning head 26. The lower ends of the dish-shaped turning head 26 and the butterfly joint 22 are provided with block-shaped reinforcing ribs, which further improve the stability of the support frame 4 after the combination. When folding, the dish-shaped turning head 26 is folded at the center line, and the dish-shaped turning head 26 is located exactly in the middle of the shaping frame 3, which can ensure that the overall weight of the bathtub body 1 is evenly distributed after folding.

[0100] like Figure 17As shown in the figure; the shaping frame 3 is composed of arc-shaped rods 27 and linear rods 28 through the insertion of connecting heads 5. Among them, the connecting head 5 can be adjusted as needed, and it can be folded and stored through different schemes. The number of the arc-shaped rods 27 is two, and they are arranged on both sides of the linear rod 28, making the bucket mouth in a long-waisted shape. The support frame 4 is composed of multiple linear rods 28 through the insertion of connecting heads 5. Select a suitable connecting head 5 for combination according to whether the support frame 4 has a folding effect. The linear rods 28 on the outside of the support frame 4 form a U-shaped structure. In the support frame 4, two linear rods 28 are inclined to form a triangular structure. The bottoms of the two side support rods 11 are inclined inward, that is, the periphery of the support frame 4 is in a U-shaped structure, which forms a rectangular structure with the linear rod in the middle of the shaping frame 3. By inserting two inclined linear rods 28, three triangles with a common side are formed inside the support frame.

[0101] As Figures 17 to 20 shown in the figure; a scheme of two-time folding storage is provided, and the support frame 4 can also be folded. Among them: a disc-shaped flipping head 26 is provided in the middle of the shaping frame 3. Both sides of the disc-shaped flipping head 26 are connected with linear rods 28. One end of the linear rod 28 far from the disc-shaped flipping head 26 is connected with the arc-shaped rod 27 through a T-shaped joint 21, forming the shaping frame 3. A T-shaped joint 21 connecting the side support rod 11 is provided in the middle of the arc-shaped rod 27. This T-shaped joint 21 is arc-shaped, and the arc is the same as that of the arc-shaped rod 27. At the corresponding position of the lower end of the support frame 4 and the disc-shaped flipping head 26, a linear flipping head 24 is also provided, so that the support frame 4 can also be folded;

[0102] Among them, an arc-shaped groove 15 is provided at the upper ends of the disc-shaped flipping head 26 and the T-shaped joint 21, and the rest of the limiting grooves are all hole grooves 14;

[0103] The arc-shaped groove 15 provided at the upper end of the disc-shaped flipping head 26 enables it to rotate on the shaping frame 3, and then带动 the support frame 4 to fold;

[0104] The T-shaped joint 21 can rotate on the arc-shaped rod 27 through the arc-shaped grooves 15 provided at both ends thereof, and carry the side support rod 11 to rotate. And a convex column 13 for fixing the T-shaped joint 21 should be provided on the arc-shaped rod 27;

[0105] The specific folding steps are as follows: first, push the support frame 4 on one side inward to break the use state of the bathtub body 1 and put it into the storage state. When pushing the support frame 4 in, the disc-shaped turning head 26 and the T-joint 21 rotate around the straight rod 28 connecting the two in the middle of the shaping frame 3. When the support frame 4 on one side rotates (folds) to exceed the center line of the shaping frame 3, the support frame 4 on the other side can be pushed in at the same time to press the support frame 4 folded first to make it close to the shaping frame. When the support frames 4 on both sides have completed the folding work, the bathtub body 1 is in a block shape, and the disc-shaped turning head 26 and the straight turning head 24 are in an adjacent state. The two folding directions are the same. Lifting the arc-shaped rod 27 on one side of the block-shaped bathtub body 1 can cause the disc-shaped turning head 26 and the straight turning head 24 to fold together, thereby realizing the second folding of the bathtub body 1.

[0106] Example 2

[0107] like Figure 21 To 23; Based on Example 1, the present application also provides a solution of twice-folding storage, and the support frame 4 cannot be folded;

[0108] Among them: a butterfly joint 22 is symmetrically provided in the middle of the shaping frame 3, so that the middle of the shaping frame 3 does not have a folding effect, and both sides of the butterfly joint 22 are connected to a straight rod 28, and the end of the straight rod 28 away from the butterfly joint 22 is connected to the arc rod 27 through a T-shaped flip head 25. The arc rod 27 can be folded inward by the T-shaped flip head 25 for storage. The middle of the arc rod 27 is provided with a T-shaped joint 21 connected to the side support rod 11;

[0109] The arc-shaped groove 15 is provided at the upper ends of the butterfly joint 22 , the T-shaped turning head 25 and the T-shaped joint 21 , and the remaining limiting grooves are all hole grooves 14 .

[0110] The upper end of the butterfly joint 22 is provided with an arc-shaped groove 15, so that it can rotate around the connected straight rod 28 on the shaping frame 3 and can carry the support frame 4 to flip inward;

[0111] The T-shaped flip head 25 has arc-shaped grooves 15 on both sides, so that it can rotate around the connected straight rod 28 and arc rod 27 on the shapeable frame 3;

[0112] The T-joint 21 can rotate on the arc-shaped rod 27 through the arc-shaped grooves 15 at both ends, and carry the side support rod 11 to rotate (fold), and the arc-shaped rod 27 should be provided with a protruding column 13 for fixing the T-joint 21;

[0113] The specific folding steps are as follows: first, push the support frame 4 on one side inward to break the use state of the bathtub body 1 and put it into the storage state. When the support frame 4 is pushed in, the butterfly joint 22 and the T-shaped flip head 25 rotate around the straight rod 28 connected to the middle of the shaping frame 3. When the support frame 4 on one side rotates (folds) to exceed the center line of the shaping frame 3, the support frame 4 on the other side can be pushed in at the same time to press the support frame 4 folded first and make it close to the shaping frame. When the support frames 4 on both sides have completed the folding work, the bathtub body 1 is now in a block shape. At this time, the folding piece of the T-shaped flip head 25 is opened downward, that is, the arc rod 27 can be folded upward by the T-shaped flip head 25. At this time, you can hold the middle of the shaping frame 3, open the side support rods 11 outward, press down the block-shaped bathtub body 1, make the two side support rods 11 contact the ground, push up the two support rods 11 through the ground, and simultaneously push up the two arc-shaped rods 27 through the two support rods 11. At this time, you can fold one side of the arc-shaped rod 27 on the shaping frame 3 first, and adjust the support rod 11 to be folded with the connected arc-shaped rod 27, and then repeat the above steps on the other side, or you can put the bathtub body 1 on its side, adjust the angle of the side support rod 11 by hand, and finally fold the arc-shaped rod 27 to complete the storage.

[0114] Example 3

[0115] like Figures 24 to 28 As shown; Based on Example 1, the present application also provides a three-fold storage solution, and the support frame 4 can be folded;

[0116] A disc-shaped turning head 26 is symmetrically provided in the middle of the shaping frame 3, where rotation and folding can occur. A straight rod 28 is connected to both sides of the disc-shaped turning head 26. The end of the straight rod 28 away from the disc-shaped turning head 26 is connected to the arc-shaped rod 27 through a T-shaped turning head 25, which can cause the support frame 4 to turn over and give the arc-shaped rod 27 the ability to fold. A T-shaped joint 21 is provided in the middle of the arc-shaped rod 27 to connect to the side support rod 11. A straight turning head 24 is also provided at the lower end of the support frame 4 corresponding to the disc-shaped turning head 26, where folding can occur.

[0117] The arc-shaped groove 15 is provided at the upper ends of the dish-shaped turning head 26 , the T-shaped turning head 25 and the T-shaped joint 21 , and the remaining limiting grooves are all hole grooves 14 .

[0118] The arc-shaped groove 15 provided on the upper end of the dish-shaped turning head 26 enables it to rotate on the shaping frame 3, thereby driving the supporting frame 4 to fold;

[0119] The arc-shaped groove 15 provided on the T-shaped flip head 25 enables it to rotate on the shaping frame 3 and enables the arc-shaped rod 27 connected thereto to have folding ability;

[0120] The T-joint 21 can rotate on the arc-shaped rod 27 through the arc-shaped grooves 15 at both ends, and carry the side support rod 11 to rotate (fold), and the arc-shaped rod 27 should be provided with a protruding column 13 for fixing the T-joint 21;

[0121] The specific folding steps are:

[0122] The first folding process is as follows: push the support frame 4 on one side inward, breaking the use state of the bathtub body 1 and putting it into the storage state. When the support frame 4 is pushed in, the disc-shaped turning head 26 and the T-joint 21 rotate around the straight rod 28 connecting the two in the middle of the shaping frame 3. When the support frame 4 on one side rotates (folds) to exceed the center line of the shaping frame 3, the support frame 4 on the other side can be pushed in at the same time, so that it presses the support frame 4 that was folded first, making it close to the shaping frame.

[0123] When the support frames 4 on both sides have completed the folding work, the bathtub body 1 is now in a block shape and the first folding is completed. At this time, the folding piece of the T-shaped turning head 25 is facing upward, and the disc-shaped turning head 26 is adjacent to the straight turning head 24;

[0124] The second folding process is that the arc-shaped rod 27 can be folded upward by the T-shaped turning head 25. At this time, the two arc-shaped rods 27 can be folded and placed on the shaping frame 3, and the position of the side support rod 11 is adjusted at the same time to complete the second folding;

[0125] The third folding process is to hold the middle of the shaping frame 3 with both hands and let gravity bend the shaping frame 3 downward naturally, that is, let gravity make the dish-shaped turning head 26 and the straight turning head 24 open naturally under the action of gravity, and then push the bottom surface of the middle of the auxiliary shaping frame 3 by hand to fit along the folding line formed by the dish-shaped turning head 26 and the straight turning head 24;

[0126] Alternatively, in step 2, the frame 3 may be partially flipped over so that the arc-shaped rods 27 are tilted to support the middle of the shaping frame 3, so that the two arc-shaped rods 27 and the curved shaping frame 3 are in a W shape, and then the two arc-shaped rods 27 on both sides are pressed inward to complete the folding.

[0127] like Figure 29 、 30 A reinforcement key 29 is provided between the two connecting rod seats 16 of the straight-line flip head 24, the T-shaped flip head 25 and the disc-shaped flip head 26. The reinforcement key 29 is a protruding key and a recessed key, which are respectively placed on the connecting rod seats 16 on different sides. When the connecting rod seat 16 is in the straight-line state, the protruding key is embedded in the recessed key, and the surface is smooth.

[0128] Working principle: The bathtub body 1 is formed by a shaping frame 3 and a supporting frame 4 which support a soft covering layer 2 through a connecting head 5. The shaping frame 3 and the supporting frame 4 are composed of fixed joints and folding joints of different styles. There are multiple locations between the shaping frame 3 and the supporting frame 4 for rotation, folding, or both rotation and folding effects. The user can decompose the bathtub body 1 from a barrel shape into blocks through reasonable and limited steps, which is convenient for the user to store. When in use, the bathtub body 1 can be reactivated by simply reversing the decomposition steps. The rotation effect is achieved by the cooperation of the arc-shaped groove 15 and the boss 13. The arc-shaped groove 15 is the movable path of the boss 13, and the folding is achieved by the cooperation of the insert 18 and the clamp 19, so that the support rods connected at both ends of the two can be folded, thereby making the shaping frame 3 and the support frame 4 have a folding effect.

[0129] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
