[0041] A specific embodiment of the present utility model, as Figures 1 to 9 shown, discloses a foldable toilet backrest, comprising a cushion 1, a wall fixing member 2 and a support frame 3; wherein, the wall fixing member 2 has a hinged end and a fixed end, and the fixed end is configured to be fixedly connected to the wall behind the toilet; the support frame 3 has a connection end and a mounting position; the mounting position is configured to mount the cushion 1; the connection end is hinged to the hinged end of the wall fixing member 2, so that the support frame 3 and the cushion 1 can rotate around the hinge to realize the folding of the backrest.

[0042] In one alternative embodiment, the support frame 3 is made of a U-shaped steel pipe, including two parallel vertical rods 31 and a cross rod 32, the cross rod 32 is connected to the front parts of the two vertical rods 31, and the rear parts of the two vertical rods 31 are respectively hinged to one of the wall fixing members 2.

[0043] Furthermore, the mounting position is located on the cross rod 32, and all or part of the cross rod 32 can also be understood as the mounting position. Specifically, the cushion 1 is mounted on the cross rod 32 through a metal plate 5 and a saddle clamp 6, and the metal plate 5 and the saddle clamp 6 are fixedly connected by screws.

[0044] In this embodiment, the riding clamp 6 and the metal plate 5 can not only fix the back cushion 1 in the middle of the steel pipe, but also enable the back cushion 1 to rotate around the cross bar 32 at a certain angle. Specifically, the interior of the riding clamp 6 has a certain damping function, so that the back cushion 1 can rotate along the axis of the cross bar 32 within a certain angle range, for example, 45° up and down around the axis of the cross bar 32. With this structural arrangement, the user can adjust the angle with his back after the back contacts the back cushion 1.

[0045] In one optional embodiment, the cushion 1 is a memory foam cushion 1. The memory foam can relieve waist pressure, provide better blood circulation, and improve comfort.

[0046] Furthermore, the surface of the back cushion 1 facing the user is concave, with both ends raised, which better fits the human body structure and further improves comfort.

[0047] It should be noted that the backrest can be made of various shapes, structures and materials, which are not particularly limited in this embodiment.

[0048] In this embodiment, the wall fixing member 2 is generally a T-shaped structure, and the wall fixing member 2 includes a connecting plate 21 and a hinge frame 22 vertically arranged on the connecting plate 21, and the connecting plate 21 is fixedly connected to the wall through expansion bolts or metal nails; the vertical rod 31 of the U-shaped steel pipe is connected to the hinge frame 22 through a rotating connection component 4. The rotating connection component 4 includes a rotating shaft 41 and a locking member 42, and the hinge end of the hinge frame 22 is rotatably connected to the vertical rod 31 of the U-shaped steel pipe through a rotating shaft 41 and a locking member 42.

[0049] In one of the optional embodiments, the rotating shaft 41 is a screw, the locking piece 42 is a nut, a first through hole 311 is provided on the vertical rod 31 of the U-shaped steel pipe, and a second through hole 221 is provided on the hinged end of the wall fixing piece 2, that is, a second through hole 221 is provided on the hinged frame 22, the screw is passed through the first through hole 311 and the second through hole 221, and the vertical rod 31 of the U-shaped steel pipe is connected to the hinged end of the wall fixing piece 2 using a nut.

[0050] Furthermore, the vertical rod 31 of the U-shaped steel tube is provided with a plurality of first through holes 311 spaced apart along the axial direction of the vertical rod 31, and the plurality of first through holes 311 can be evenly arranged. Since the rotating connection assembly 4 is a disassembly structure, the vertical rod 31 can be removed separately, and the distance between the cushion 1 and the wall can be adjusted by inserting the rotating shaft 41 into the first through holes 311 at different positions on the vertical rod 31, and there is no need to disassemble repeatedly after adjustment.

[0051] In this embodiment, the wall fixing member 2 is not only used for being fixedly connected to the wall and hinged to the support frame 3, but also used for maintaining the backrest in a folded state and a use state, and switching between the two states.

[0052] In order to stably maintain the toilet backrest in the use state and the folded state, the hinge frame 22 is provided with a first rotation limiting portion and a second rotation limiting portion. The first rotation limiting portion and the second rotation limiting portion cooperate to enable the vertical rod 31 of the U-shaped steel pipe to rotate 90° around the rotating shaft 41 between the horizontal plane and the vertical plane and stop.

[0053] In an alternative embodiment, the hinge frame 22 has a rotation space 222. The top of the rotation space 222 is closed by a top plate 223. The lower part and the front end of the rotation space 222 are open. The rear end opening of the rotation space 222 is sealed by a connecting plate 21. The cross-sectional area of the hinge frame 22 is an inverted U-shape, and this cross-section is parallel to the connecting plate 21; the rear part of the vertical rod 31 of the U-shaped steel pipe is installed in the rotation space 222 and can rotate in the rotation space 222 around the rotating shaft 41. The rear part has a certain length. That is to say, there is still a certain length between the first through hole 311 on the vertical rod 31 and the rearmost end of the vertical rod 31. This section is called the limiting section 312; when the vertical rod 31 of the U-shaped steel pipe rotates to the horizontal position, the limiting section 312 at the rear part of the vertical rod 31 contacts the top wall surface 224 of the rotation space 222, and the top wall surface 224 defines the horizontal rotation position of the vertical rod 31. At this time, it is the use state of the backrest. Here, the top wall surface 224 of the rotation space 222 serves as the first rotation limiting portion. When the backrest needs to be switched from the use state to the folded state, the vertical rod 31 of the U-shaped steel pipe is rotated upward. When it rotates to the vertical state, the outer wall of the vertical rod 31 abuts against the front end of the top plate 223, and the front end of the top plate 223 defines the vertical rotation position of the vertical rod 31. Here, the front end of the top plate 223 serves as the second rotation limiting portion.

[0054] Preferably, an inner concave arc-shaped structure 225 is provided at the front end break of the top plate 223. The inner concave radian of the inner concave arc-shaped structure 225 is adapted to the circular outer wall contour of the vertical rod 31. When the circular outer wall of the vertical rod 31 contacts the inner concave arc-shaped structure 225 at the front end of the top plate 223, the toilet backrest is just in the folded state. Here, the inner concave arc-shaped structure 225 serves as the second rotation limiting portion.

[0055] Furthermore, the rotation connection assembly 4 further includes two pipe wall washers 43. That is, each set of rotation connection assembly 4 includes a rotating shaft 41, a nut and two pipe wall washers 43. The two pipe wall washers 43 are located on both sides of the vertical rod 31 and are within the rotation space 222 of the hinge frame 22. The pipe wall washers 43 are in extrusion contact with the inner side wall of the rotation space 222 and the outer wall of the vertical rod 31. Among them, the pipe wall washers 43 can be made of plastic material. By providing the plastic pipe wall washers 43, the vertical rod 31 can have a certain damping when rotating.

[0056] Further, the pipe wall gasket 43 is provided with a through hole for the rotating shaft 41 to pass through. The pipe wall gasket 43 is provided with an inner concave surface 431, and the inner concave surface 431 can be attached to the circumferential surface of the vertical rod 31 and can rotate around the rotating shaft 41 together with the vertical rod 31.

[0057] Compared with the prior art, the foldable toilet backrest provided in this embodiment can achieve the following beneficial effects:

[0058] 1. The backrest is designed to be foldable, which solves the problem that the original toilet lid cannot be closed after installing the toilet backrest in the prior art, can meet the needs of different people when using the toilet, users can independently choose whether to use the backrest, and at the same time the toilet lid can still be opened and closed freely, improving the flexibility of the backrest.

[0059] 2. By providing a first rotation limiting portion and a second rotation limiting portion on the hinge frame, the structures of the two rotation limiting portions are simple, and the cooperation of the two can enable the vertical rod of the U-shaped steel pipe to rotate 90° between the horizontal plane and the vertical plane around the rotating shaft and stop, realizing the switching between the use state and the folded state of the toilet backrest.

[0060] 3. A plurality of first through holes are axially provided on the vertical rod of the U-shaped steel pipe, and the plurality of first through holes can be evenly arranged. A rotation connection component with a detachable structure is adopted, so that the vertical rod can be detached separately, and the distance between the cushion and the wall surface can be adjusted by inserting the rotating shaft into different first through holes on the vertical rod, and there is no need to disassemble repeatedly after adjustment.

[0061] The specific embodiments described above have further elaborated the purpose, technical solutions and beneficial effects of the present application. It should be understood that the above are only specific embodiments of the present application and are not used to limit the protection scope of the present application.
