[0021] From the above description of the present application and its preferred embodiments, relative to the prior art, the technical scheme of the present application and its preferred embodiments has the following beneficial effects due to the use of the following technical means:

[0022] 1. In scheme one and its preferred embodiments, a hinge suitable for rotating the second door body relative to the first door body, the hinge comprising a first hinge, a rotary joint, a second hinge and a first torsional spring. The first hinge is fixed relative to the first door body, one end of the rotary joint is suitable for rotating connection with the first hinge around the first axis, the second hinge is suitable for rotationally connecting with the second door body to rotate synchronously with the second door body; the second hinge and the other end of the rotary joint are rotationally connected around the second axis parallel to the first axis, so that the second hinge can rotate relative to the rotary joint, and the position of the second hinge relative to the first hinge can change due to the rotation of the rotary joint relative to the first hinge.

[0023] The first mounting end is fixed to one of the rotary joint and the second hinge, and the first abutting end abuts the other of the rotary joint and the second hinge,

[0024] When rotating the second door body in the forward direction, due to the presence of the first torsional spring, the second hinge and the rotary joint will not rotate relative to each other, and the rotation freedom is limited to a certain extent, and will not be chaotic, and the force of the second door body acting on the rotary joint will be transmitted to the rotary joint through the first torsional spring, so that the rotary joint and the second hinge rotate synchronously relative to the first hinge, achieving the purpose of rotating the second door body. When the forward rotation of the rotary joint is limited, the force of the first torsional spring can be overcome to realize the rotation of the second hinge (second door body) relative to the rotary joint, thereby realizing more states.

[0025] 2. In Scheme 2 and its preferred embodiments, one of the rotary joint and the second hinge is provided with a mounting portion extending in a direction parallel to the first axis, and the mounting portion is provided with a mounting groove; the other is provided with a limiting post extending in a direction parallel to the first axis; the first torsion spring is provided with a first mounting end and a first abutting end, the first mounting end is placed in the mounting groove, and the first abutting end abuts against one side of the limiting post to provide a force that prevents the second hinge from rotating in the forward direction relative to the rotary joint, so as to realize the installation of the torsion spring.

[0026] 3. In Scheme 3 and its preferred embodiments, the rotary joint is adapted to rotate forward relative to the first hinge from its initial position until it abuts against at least one of the first door body, the first hinge, and the crossbeam, so that the rotary joint is located in the first limiting position. Braking of the rotary joint is achieved by abutting against the corresponding parts, eliminating the need for manual operation and making it more convenient. The second hinge is adapted to overcome the force applied by the first torsion spring when the rotary joint rotates to the first limiting position, so that it rotates forward relative to the rotary joint to the first folding position. Since the rotary joint cannot continue to rotate forward at this time, the second hinge rotates until the first folding position. During this process, the user does not need to change the operation method to achieve the rotation of the second hinge to the first folding position, making the operation simple.

[0027] 4. In Scheme 4 and its preferred embodiments, during the above process, the second hinge and the rotary joint will not rotate relative to each other and will not cause disorder when rotating only in the forward direction. This scheme also includes a second torsion spring, which has a second mounting end and a second abutting end. The second mounting end is placed in the mounting groove, and the second abutting end abuts against the other side of the limiting post to provide a force that prevents the second hinge from rotating relative to the rotary joint in the reverse direction, so that disorder will not occur when rotating in the reverse direction.

[0028] 5. In Scheme 5 and its preferred embodiments, the rotary joint is adapted to rotate in the opposite direction relative to the first hinge from its initial position until it abuts against at least one of the first door body, the first hinge, and the crossbeam, so that the rotary joint is located in the second limiting position. Braking of the rotary joint is achieved by abutting against the corresponding parts, eliminating the need for manual operation and making it more convenient. The second hinge is adapted to overcome the force applied by the second torsion spring when the rotary joint rotates to the second limiting position, so as to rotate in the opposite direction relative to the rotary joint to the second folding position. Since the rotary joint cannot continue to rotate in the opposite direction at this time, the second hinge rotates until it reaches the second folding position. During this process, the user does not need to change the operating method to achieve the rotation of the second hinge to the second folding position, making the operation simple. Furthermore, the second door body can achieve the door opening action by rotating forward or backward relative to the first door body, facilitating user entry and exit.

[0029] 6. In Scheme 6 and its preferred embodiments, the first and second top abutments are hook-shaped. Compared with straight shapes, hooks have better wrapping properties with the mounting part and are less likely to detach from the limiting post. Of course, in other schemes, the first and second top abutments can also be straight.

[0030] 7. In Scheme 7 and its preferred embodiments, since the first torsion spring and the second torsion spring are installed in the same position, if the first torsion spring and the second torsion spring are in contact, they may interfere with each other, causing the corresponding action to fail. This scheme also includes an isolation gasket, which is disposed in the mounting part to achieve installation. The isolation gasket is located between the first torsion spring and the second torsion spring to prevent interference between the first torsion spring and the second torsion spring.

[0031] 8. In Scheme 8 and its preferred embodiments, a first limiting gasket and a second limiting gasket are further included. The first limiting gasket and the second limiting gasket are disposed on the mounting part to achieve installation. The first limiting gasket is located at the end of the first torsion spring away from the second torsion spring, and the second limiting gasket is located at the end of the second torsion spring away from the first torsion spring, so that the working positions of the first torsion spring and the second torsion spring are determined. That is, the space between the first limiting gasket and the isolation gasket is the working space of the first torsion spring, and the space between the second limiting gasket and the isolation gasket is the working space of the second torsion spring, so that during use, the first torsion spring and the second torsion spring are not easily disengaged due to swaying.

[0032] 9. In Scheme Nine and its preferred embodiments, a door assembly includes a first door body, a second door body, and a hinge as described above. The number of hinges is two, and they are located at the two ends of the first door body and the second door body, respectively, so as to make the force more stable and have the beneficial effects brought by the hinge described above.

[0033] 10. In Scheme 10 and its preferred embodiments, the first hinge is integrally formed with the first door body, and the second hinge is integrally formed with the second door body, thereby reducing the number of parts.

[0034] 11. In Scheme 11 and its preferred embodiments, a shower room includes a third door and the aforementioned door assembly. The first door and the third door are coplanar and have a first opening between them. When the rotary joint and the second hinge are in the initial position, the second door is adapted to close the first opening. The first opening can be opened and closed by rotating the second door, and the beneficial technical effects brought about by the aforementioned hinge are achieved.

[0035] 12. In Scheme Twelve and its preferred embodiments, a fourth door is also included. The fourth door is perpendicular to the first door and has a second opening between them. The rotary joint is adapted to rotate in the opposite direction to the first hinge from its initial position to a second limiting position that abuts against the first door or the first hinge. When the rotary joint is in the second limiting position and the second door and the third door are coplanar, the second door is adapted to close the second opening. By cooperating with the wall, the shower room can achieve functions such as dry and wet separation. Attached Figure Description

[0064] In this embodiment, the first door body 20, the third door body 40 and the fourth door body 50 are fixed doors, the first door body 20 and the third door body 40 are coplanar and have a first opening 60 therebetween, one end of the first door body 20 away from the third door body 40 is connected with the left side wall, one end of the third door body 40 away from the first door body 20 is connected with the right side wall, and the inner sides of the first door body 20 and the third door body 40 are the shower room space.

[0065] The fourth door body 50 is perpendicular to the first door body 20 and located in the shower room space, and divides the shower room space into two spaces, which can be set as dry and wet separation. The fourth door body 50 and the first door body 20 have a second opening 70 therebetween. One end of the fourth door body 50 away from the first door body 20 is connected with the inner side wall.

[0066] Reference Figures 1-6 The hinge 10 includes a first hinge 1, a rotary joint 2, a second hinge 3, a first torsional spring 4, a second torsional spring 5, an isolation gasket 6, a first limiting gasket 7 and a second limiting gasket 8.

[0067] The first hinge 1 is fixed relative to the first door body 20, that is, there is no relative motion between them during use, for example, the first hinge 1 can be rotationally connected with the cross beam 80 (as shown in Figure 17 ), or can be rotationally connected with the first door body 20, the rotationally connected mode can be adhesive, screw locking, or setting rotation stopping structure, integrally made, etc. Reference Figure 18The first door body 20 comprises a door plate 201 and a door frame 202. The door plate 201 is usually a glass piece which is not easy to process. If the first hinge 1 is rotationally connected with the first door body 20, the first hinge 1 can be rotationally connected with the door frame 202 to facilitate processing and installation.

[0068] One end of the rotary joint 2 is adapted to be rotationally connected with the first hinge 1 about the first axis, and the other end of the rotary joint 2 is rotationally connected with the second hinge 3 about the second axis which is parallel to the first axis. The rotationally connected mode can be the mode that the shaft sleeve is matched with the rotation hole. In the embodiment, the rotary joint 2 has three use positions, which are respectively an initial position, a first limit position and a second limit position. Referring to Figure 7 In the initial position, the rotary joint 2 is coplanar with the first door body 20, and is used to close the first opening 60. Figure 9 The rotary joint 2 is adapted to abut against at least one of the first door body 20, the first hinge 1 and the cross beam 80 along the forward direction of the initial position (in the embodiment, counterclockwise) relative to the first hinge 1, so that the rotary joint 2 is located at the first limit position. Figure 13 The rotary joint 2 is adapted to abut against at least one of the first door body 20, the first hinge 1 and the cross beam 80 along the reverse direction of the initial position (in the embodiment, clockwise) relative to the first hinge 1, so that the rotary joint 2 is located at the second limit position, and is used to open the first opening 60. In the embodiment, the rotary joint 2 abuts against the first door body 20 and the cross beam 80 to be located at the first limit position and the second limit position. For details, refer to Figure 5 The rotary joint 2 comprises an arc surface 21 and two straight surfaces 22 connected with the arc surface 21. The subtended central angle of the arc surface 21 is 180 degrees. When one straight surface 22 abuts against the first door body 20 and the cross beam 80, the rotary joint 2 reaches the first limit position. When the other straight surface 22 abuts against the first door body 20 and the cross beam 80, the rotary joint 2 reaches the second limit position. In other embodiments, corresponding limit protrusions can be arranged on the first door body 20, the first hinge 1 or the cross beam 80. The limit protrusions are on the rotation path of the rotary joint 2. When the rotary joint 2 touches the limit protrusions, the rotary joint 2 reaches the limit position.

[0069] The second hinge 3 is adapted to be rotationally connected with the second door body 30. The rotationally connected mode can be adhesion, screw locking, or setting a rotation-stopping structure, integrally manufactured, etc. In the embodiment, the second hinge 3 is provided with a plug-in column, and the door frame 202 of the second door body 30 is provided with a plug-in slot. The plug-in column and the plug-in slot are rotationally plugged in. The other end of the rotary joint 2 is rotationally connected with the second hinge 3 about the second axis. One of the rotary joint 2 and the second hinge 3 is provided with an installation part 23 extending in the direction parallel to the first axis, and the installation part 23 is provided with an installation slot 231. The other of the rotary joint 2 and the second hinge 3 is provided with a limit column 31 extending in the direction parallel to the first axis. In the embodiment, refer to Figure 4 ,Figure 5 The rotating joint 2 is provided with a mounting portion 23, a mounting groove 231 penetrating through the mounting portion 23 in a direction perpendicular to the second axis and opening towards the second hinge 3 to facilitate mounting of the first torsion spring 4 and the second torsion spring 5. The second hinge 3 is provided with a limiting post 31.

[0070] With reference to Figure 6 The first torsion spring 4 is provided with a first mounting end 41 and a first abutting end 42, the first mounting end 41 being fixed to one of the rotating joint 2 and the second hinge 3, and the first abutting end 42 abutting the other one of the rotating joint 2 and the second hinge 3. Specifically, the first mounting end 41 is disposed in the mounting groove 231 and acts on the groove wall of the mounting groove 231; the first abutting end 42 is hook-shaped and abuts the outer wall of the limiting post 31, and the first abutting end 42 abuts one side of the limiting post 31 to provide a force resisting the second hinge 3 from rotating in the positive direction relative to the rotating joint 2. Therefore, when a positive rotating force is applied to the second door body 30, the rotating joint 2 and the second hinge 3 will initially rotate in the positive direction synchronously, i.e., the second door body 30 and the rotating joint 2 rotate in the positive direction synchronously. When the rotating joint 2 rotates in the positive direction to the first limiting position, the rotating joint 2 cannot continue to rotate in the positive direction, at which time the second hinge 3 is adapted to overcome the elastic force exerted by the first torsion spring 4 to rotate in the positive direction relative to the rotating joint 2 to the first folding position.

[0071] With reference to Figure 6 The second torsion spring 5 is provided with a second mounting end 51 and a second abutting end 52, the second mounting end 51 being disposed in the mounting groove 231 and acting on the groove wall of the mounting groove 231; the second abutting end 52 is hook-shaped and abuts the outer wall of the limiting post 31, and the second abutting end 52 abuts the other side of the limiting post 31 to provide a force resisting the second hinge 3 from rotating in the reverse direction relative to the rotating joint 2. The second abutting end 52 and the first abutting end 42 are opposite in direction. When a reverse rotating force is applied to the second door body 30, the rotating joint 2 and the second hinge 3 will initially rotate in the reverse direction synchronously, i.e., the second door body 30 and the rotating joint 2 rotate in the reverse direction synchronously. When the rotating joint 2 rotates in the reverse direction to the second limiting position, the rotating joint 2 cannot continue to rotate in the reverse direction, at which time the second hinge 3 is adapted to overcome the elastic force exerted by the second torsion spring 5 to rotate in the reverse direction relative to the rotating joint 2 to the second folding position.

[0072] With reference to Figure 3 The isolating gasket 6 is disposed on the mounting portion 23 and located between the first torsion spring 4 and the second torsion spring 5. In this embodiment, the isolating gasket 6 is sleeved on the mounting portion 23.

[0073] The first limiting gasket 7 and the second limiting gasket 8 are sleeved on the mounting portion 23; the first limiting gasket 7 is located at one end of the first torsion spring 4 away from the second torsion spring 5, and the second limiting gasket 8 is located at one end of the second torsion spring 5 away from the first torsion spring 4.

[0074] The following is a detailed description of its working state: (the second hinge 3 action is consistent with the second door body 30 action)

[0075] The first torsional spring 4 and the second torsional spring 5 are independent, when the second door body 30 is forward rotation, the second torsional spring 5 is in the free state, when the second door body 30 is reverse rotation, the first torsional spring 4 is in the free state. In order to make the drawing more clear, only the torsional spring in action is drawn.

[0076] Close the first opening 60 state: reference Figure 7 、 Figure 8 When the second door body 30 is in the closed state, the first door body 20, the second door body 30 and the third door body 40 are coplanar, the rotary joint 2 and the second hinge 3 are in the initial position, at this time. The second door body 30 closes the first opening 60. At this time, the second door body 30 is suitable for both the inside opening door and the outside opening door.

[0077] Open 90°: reference Figure 9 、 Figure 10 When the second door body 30 is forward rotation to open outward, due to the action of the first torsional spring 4, the second hinge 3 is hindered to rotate in the positive direction relative to the rotary joint 2, so it will be shown that the rotary joint 2 and the second hinge 3 will rotate in the positive direction at first, until reaching the 90° opening position, at this time, the straight surface 22 of the rotary joint 2 is in contact with the first door body 20 and the cross beam 80, the rotary joint 2 reaches the first limit position and cannot continue to rotate in the positive direction.

[0078] Open 180°: reference Figure 11 、 Figure 12 Based on the 90° opening state, continue to rotate the second door body 30 in the positive direction, due to the rotary joint 2 cannot continue to rotate in the positive direction, the force will be borne by the second hinge 3, the second hinge 3 is suitable to overcome the force exerted by the first torsional spring 4, forcing the first torsional spring 4 to elastically deform to rotate in the positive direction relative to the rotary joint 2 to the first folding position, that is, the 180° opening.

[0079] When starting to close from the 180° opening position, due to the action of the first torsional spring 4, the whole closing process first performs a rotating action to release the torsional force of the first torsional spring 4, that is, the second hinge 3 first rotates in the reverse direction relative to the rotary joint 2 to the 90° opening state, when continuing to close, due to the existence of the second torsional spring 5, the rotary joint 2 and the second hinge 3 will rotate in the reverse direction at the same time, until reaching the closed first opening 60 state.

[0080] Open 90°: reference Figure 13 、 Figure 14When the second door body 30 is reversely rotated to open inward, the second hinge 3 is hindered from rotating in the reverse direction relative to the rotary joint 2 due to the action of the second torsion spring 5, so that the rotary joint 2 and the second hinge 3 will initially rotate in the reverse direction synchronously until reaching the 90-degree inward opening position. At this time, the other flat surface 22 of the rotary joint 2 abuts against the first door body 20 and the cross beam 80, and the rotary joint 2 reaches the second limiting position and cannot continue to rotate in the reverse direction. At this time, the second door body 30 is coplanar with the third door body 40, and the second door body 30 is closed.

[0081] 180-degree inward opening: refer to Figure 15 、 Figure 16 Based on the 90-degree inward opening state, when the second door body 30 is continuously rotated in the reverse direction, the second hinge 3 is adapted to overcome the elastic force exerted by the second torsion spring 5 to force the second torsion spring 5 to elastically deform to rotate in the reverse direction relative to the rotary joint 2 to the second folding position, i.e., the 180-degree inward opening position. At this time, the first opening 60 and the second opening 70 are both open.

[0082] When the door is closed from the 180-degree inward opening position, due to the action of the torsion force of the second torsion spring 5, the entire closing process first performs a rotating action of releasing the torsion force of the second torsion spring 5, i.e., the second hinge 3 first rotates in the forward direction relative to the rotary joint 2 to the 90-degree inward opening state. When the closing action continues, the rotary joint 2 and the second hinge 3 will synchronously rotate in the forward direction due to the presence of the first torsion spring 4 until reaching the closed first opening 60 state.

[0083] Through the hinge 10, the second door body 30 can have multiple states relative to the first door body 20, which is convenient for the user to use, and is not prone to disorder during use, making the operation more simple.

[0084] Compared with the prior art, the embodiment has the following beneficial effects:

[0085] In an exemplary embodiment, a hinge 10 is adapted to rotate a second door body 30 relative to a first door body 20, and the hinge 10 comprises a first hinge 1, a rotary joint 2, a second hinge 3, and a first torsion spring 4. The first hinge 1 is fixed relative to the first door body 20, one end of the rotary joint 2 is adapted to be rotationally connected with the first hinge 1 about a first axis, and the second hinge 3 is adapted to be rotationally connected with the second door body 30 to rotate synchronously with the second door body 30. The second hinge 3 is rotationally connected with the other end of the rotary joint 2 about a second axis parallel to the first axis, so that the second hinge 3 can rotate relative to the rotary joint 2 and can change the position relative to the first hinge 1 due to the rotation of the rotary joint 2 relative to the first hinge 1.

[0086] The rotation joint 2 and the second hinge 3 are provided with a mounting part 23 extending along the direction parallel to the first axis, the mounting part 23 is provided with a mounting groove 231, and the other is provided with a limiting column 31 extending along the direction parallel to the first axis; the first torsion spring 4 is provided with a first mounting end 41 and a first abutting end 42, the first mounting end 41 is arranged in the mounting groove 231, and the first abutting end 42 abuts against one side of the limiting column 31 to provide a force resisting the forward rotation of the second hinge 3 relative to the rotation joint 2; when the second door body 30 rotates in the forward direction, the second hinge 3 and the rotation joint 2 will not rotate relative to each other due to the existence of the first torsion spring 4, the rotation freedom is limited to a certain extent, and disorder will not occur, and the force acting on the rotation joint 2 by the second door body 30 will be transmitted to the rotation joint 2 through the first torsion spring 4, so that the rotation joint 2 and the second hinge 3 rotate synchronously relative to the first hinge 1, and the purpose of rotating the second door body 30 is achieved. When the forward rotation of the rotation joint 2 is limited, the force of the first torsion spring 4 can be overcome to realize the rotation of the second hinge 3 (the second door body 30) relative to the rotation joint 2, thereby realizing more states.

[0087] In an exemplary embodiment, the rotation joint 2 is adapted to rotate relative to the first hinge 1 in the forward direction from the initial position to abut against at least one of the first door body 20, the first hinge 1 and the cross beam 80, so that the rotation joint 2 is located at the first limiting position, and the rotation joint 2 is braked by abutting against the corresponding part, without the need for manual operation, which is more convenient; the second hinge 3 is adapted to overcome the force exerted by the first torsion spring 4 to rotate relative to the rotation joint 2 in the forward direction to the first folding position when the rotation joint 2 rotates to the first limiting position, so that the second hinge 3 rotates until the first folding position due to the fact that the rotation joint 2 cannot continue to rotate in the forward direction at this time, and the user does not need to change the operation mode to realize the rotation of the second hinge 3 to the first folding position, which is simple to operate.

[0088] In an exemplary embodiment, in the above process, only when rotating in the forward direction, the second hinge 3 and the rotation joint 2 will not rotate relative to each other, and disorder will not occur, and the scheme further comprises a second torsion spring 5, the second torsion spring 5 is provided with a second mounting end 51 and a second abutting end 52, the second mounting end 51 is arranged in the mounting groove 231, and the second abutting end 52 abuts against the other side of the limiting column 31 to provide a force resisting the reverse rotation of the second hinge 3 relative to the rotation joint 2, so that when rotating in the reverse direction, disorder will not occur.

[0089] In an exemplary embodiment, the rotary joint 2 is adapted to rotate reversely relative to the first hinge 1 to the initial position to abut against at least one of the first door body 20 and the first hinge 1 and the cross beam 80, so that the rotary joint 2 is located at the second limiting position, and the braking of the rotary joint 2 is achieved by abutting against the corresponding part without manual operation, which is more convenient; the second hinge 3 is adapted to overcome the force exerted by the second torsional spring 5 to rotate reversely relative to the rotary joint 2 to the second folding position when the rotary joint 2 rotates to the second limiting position. Since the rotary joint 2 cannot continue to rotate reversely at this time, the second hinge 3 rotates until the second folding position, and in this process, the user does not need to change the operation mode to achieve the rotation of the second hinge 3 to the second folding position, which is simple to operate. And in this way, the forward rotation and the reverse rotation of the second door body 30 relative to the first door body 20 can both achieve the door opening action, which is convenient for the user to enter and exit.

[0090] In an exemplary embodiment, the first top abutting end 42 and the second top abutting end 52 are hook-shaped, which has better wrapping performance than linear shape and is not easy to separate from the limiting column 31. Of course, in other schemes, the first top abutting end 42 and the second top abutting end 52 can also be linear.

[0091] In an exemplary embodiment, since the installation positions of the first torsional spring 4 and the second torsional spring 5 are the same, if the first torsional spring 4 and the second torsional spring 5 are attached, interference between them may occur, which causes the corresponding action to be unable to be achieved. The present scheme further includes an isolation gasket 6, which is arranged on the mounting portion 23 to be installed, and is located between the first torsional spring 4 and the second torsional spring 5 to prevent interference between the first torsional spring 4 and the second torsional spring 5.

[0092] In an exemplary embodiment, the first limiting gasket 7 is located at one end of the first torsional spring 4 away from the second torsional spring 5, and the second limiting gasket 8 is located at one end of the second torsional spring 5 away from the first torsional spring 4, so that the working positions of the first torsional spring 4 and the second torsional spring 5 are determined, i.e., the space between the first limiting gasket 7 and the isolation gasket 6 is the working space of the first torsional spring 4, and the space between the second limiting gasket 8 and the isolation gasket 6 is the working space of the second torsional spring 5, so that in the use process, the first torsional spring 4 and the second torsional spring 5 are not easy to be unhooked due to deflection.

[0093] In an exemplary embodiment, a door assembly includes a first door body 20, a second door body 30, and two hinges 10 as described above, which are located at both ends of the first door body 20 and the second door body 30, respectively, so that the stress is more stable, and has the beneficial effects of the hinge 10 described above.

[0094] In an exemplary embodiment, the first hinge 1 is integrally formed with the door frame 202 of the first door 20, and the second hinge 3 is integrally formed with the door frame 202 of the second door 30, thereby reducing the number of parts.

[0095] In an exemplary embodiment, a shower room includes the third door 40 and the door assembly, the first door 20 and the third door 40 are coplanar and have a first opening 60 therebetween, the second door 30 is adapted to close the first opening 60 when the rotary joint 2 and the second hinge 3 are in the initial position, and the first opening 60 can be opened and closed by rotating the second door 30, and has the beneficial technical effects of the hinge 10.

[0096] In an exemplary embodiment, the shower room further includes a fourth door 50, the fourth door 50 is perpendicular to the first door 20 and has a second opening 70 therebetween, the rotary joint 2 is adapted to rotate relative to the first hinge 1 to a second limit position abutting the first door 20 or the first hinge 1 in the reverse direction of the initial position, the second door 30 is adapted to close the second opening 70 when the rotary joint 2 is in the second limit position and the second door 30 is coplanar with the third door 40, and the shower room can realize dry and wet separation and other functions by cooperating with the wall.
