The plate 21 and the through holes opened in the side walls of the supporting bent plate 21 are all fixed with connecting rods 22, and one end of the connecting rods 22 is connected to a moving wheel 1 23 with limited rotation. One side of the moving wheel 1 23 is provided with a moving wheel 2 24 installed on the support frame 1. The two moving wheels 1 23 are manual wheels, and the two moving wheels 24 are universal rollers. The shape and composition structure of the moving wheel 1 23 are consistent with the tires of the existing wheelchair. A metal ring for manual rotation is fixed on the outside of the rubber wheel. When the user needs to move the toilet chair by himself, he can move the toilet chair as a whole by operating the metal rings on the moving wheel 1 23 with both hands. The two moving wheels 24 are universal rollers. Because the two universal rollers are installed at the front end of the toilet chair, it is convenient to The toilet chair turns as a whole when moving. In addition, both the moving wheel 1 23 and the moving wheel 2 24 are designed with silent wheels, and are light and easy to move with less effort. Brake lock assemblies 4 for limiting the moving wheel 1 23 are installed on the two supporting bent plates 21. A silicone seat cushion 5 and a backrest board 6 are arranged between the two sets of brake lock assemblies 4. The silicone seat cushion 5 is made of imported soft silicone, which has the advantages of outstanding anti-aging and corrosion resistance, excellent buffering and shock absorption ability, low stain adhesion, and easy cleaning. At the same time, the silicone seat cushion 5 has good anti-slip performance, which prevents the user from slipping and falling after sitting on the silicone seat cushion 5. A toilet opening 7 is provided on the surface of the silicone seat cushion 5, and the backrest board 6 is fixed to the surface of the support frame 1. The backrest board 6 is made of imported soft silicone. The backrest 6 is made of plastic, and heat dissipation vents 13 are equidistantly provided on the backrest plate 6. The backrest plate 6 conforms to the shape of the human back, and can support the patient's back when the patient sits on the toilet chair. The heat dissipation vents 13 allow the user to breathe when leaning on the backrest plate 6, avoiding the back from feeling stuffy and uncomfortable. When using this movable lifting toilet chair, the entire movable lifting toilet chair adopts a full set of waterproof function design. When the toilet chair is used later, the electric control box 3 and the lifting mechanism 8 are waterproofed, so direct scrubbing will not affect the normal use of the two. When the patient who is unable to walk on his own after being bedridden uses it, the caregiver can move the toilet chair to the bedside and then lift the user onto the toilet chair.Then, the toilet chair can be moved to the bathroom by the caregiver pushing it or the user operating the moving wheels 23 by themselves. When the toilet chair is moved to the bathroom, the brake lock components 4 provided on both sides of the support frame 1 can limit the two moving wheels 23 to prevent them from moving. When the user is using the toilet, the silicone seat cushion 5 can be adjusted to an appropriate height by activating the lifting mechanism 8 to improve the user's comfort when using the toilet. When the user needs to stand up, the lifting component 8 can be activated again to slowly lift the silicone seat cushion 5 to the maximum extent, thereby assisting the user to stand up. When the user needs to go indoors or outdoors for activities, the toilet chair can be moved as a whole by their own operation or by pushing it by a caregiver. In addition, a language alarm and broadcast function can be added to the toilet chair as a whole, so that when the user falls, they can call for help in time. For special users, in order to relieve their mental stress, the toilet chair can also be equipped with a light music playback function to further improve the functionality of the toilet.

[0030] like Figure 5 As shown, in some embodiments, the brake lock assembly 4 includes a support member 41 fixed to a side wall of the support bent plate 21, an operating rod 42 and a brake member 43 are rotatably connected to the support member 41, a brake rod 44 is fixed to one side wall of the brake member 43, and the brake rod 44 is a metal rod with anti-skid convex patterns on the surface, and the purpose of the anti-skid convex patterns is to increase the friction after it contacts the rubber tread of the moving wheel 23, thereby making the moving wheel 23 more stable after being limited, and a transmission member 45 is movably connected to the operating rod 42, and the other end of the transmission member 45 is connected to the brake member 43. The vehicle part 43 is movably connected. When in use, by rotating the operating lever 42 to one side, the brake part 43 can be driven to rotate with the cooperation of the transmission part 45. After the brake part 43 rotates, it will drive the brake lever 44 to fit the rubber tire surface of the moving wheel 23. At this time, the entire toilet chair can be braked when moving. The operating lever 42 is adapted to the user's hand, which is convenient for operation. In addition, all components are connected in a limited movably manner, so that when in use, the stability of the components in the brake lock assembly 4 can be guaranteed when used in combination.

[0031] like Figure 2 、 Figure 3 、 Figure 4 and Figure 6As shown, in some embodiments, a lifting mechanism 8 for driving the silicone seat cushion 5 to flip is further included. The lifting mechanism 8 includes two connecting members 81 fixed to the surface of the support frame 1. The connecting members 81 are movably connected to an electric push rod 82. A round rod 83 is fixed to the support frame 1. The surface of the round rod 83 is rotatably connected to a flip frame 84. Since the silicone seat cushion 5 has good anti-slip performance, the patient can avoid slipping and falling after sitting on the silicone seat cushion 5. In addition, in order to further enhance the safety of the user sitting on the toilet chair, a safety belt is also installed on the flip frame 84, and the safety belts on both sides are fixed by means of buckle clamping, and the length of the installation belt can be freely adjusted, which can enhance the self-care ability of some users with poor self-care ability. The safety of the user sitting on the toilet chair is ensured, but the safety belt part is not shown in the figure. The ejection ends of the two electric push rods 82 are rotatably connected to the flip frame 84, and the silicone cushion 5 is installed on the top of the flip frame 84. The top of the flip frame 84 is equipped with a side armrest assembly 85, which includes two side armrests 851 fixed on the top of the flip frame 84. The surfaces of the side armrests 851 are fixed with hand protection covers 852, armrest plates 853 and controllers 854. When the user's hand and the side armrests 851 are held by hand, the hand protection covers 852 can enhance the friction between the hand and the surface of the side armrests 851, thereby playing an anti-slip effect and making the hand more comfortable. The armrest plates 853 are provided. The utility model is made of plastic, and its purpose is that when the user gets up after using the toilet, if the user does not need to use the lifting mechanism, the user can get up by holding the armrests 853 on both sides. At the same time, it can also play an auxiliary role when sitting down. The two controllers 854 are provided to facilitate the control of the start and stop of the two electric push rods 82. One controller 854 is used to control the lifting operation of the ejecting ends of the two electric push rods 82, and the other controller 854 is used to control the lowering operation of the ejecting ends of the two electric push rods 82. When the user needs to lift the silicone seat cushion 5 before using the toilet, the user can operate the lifting controller 854 on one of the side support rods 851 to control the two electric push rods 82 to start, and then The ejection ends of the two electric push rods 82 will extend out. Since the ejection ends of the two electric push rods 82 are rotatably connected to the flip frame 84, and one side wall of the flip frame 84 is limited and rotatably connected to the round rod 83, the lifted flip frame 84 will rotate and rise along the round rod 83, so that the user can adjust it to a suitable height for toilet operation. When the flip frame 84 needs to be flipped down and reset, the user can operate the descent controller 854 on the other side handrail 851, and then control the ejection ends of the two electric push rods 82 to move downward, and then the flip frame 84 can be rotated and reset; in addition, the two controllers 854 control the two electric push rods 82 wirelessly, avoiding the subsequent inconvenience caused by wiring.

[0032] like Figure 1 As shown, in some embodiments, a U-shaped fixing rod 9 is fixed to the surface of the support frame 1, and a footrest 10 is movably connected to the surface of the U-shaped fixing rod 9. A plastic plate 11 is fixed to the top of the footrest 10, and anti-slip bumps 12 are fixed to the top of the plastic plate 11 at equal intervals. The footrest 10 is made of metal material, and the plastic plate 11 is fixed to its top. The anti-slip bumps 12 fixed at equal intervals on the top of the plastic plate 11 can enhance the friction between the user's feet and the plastic plate 11 after contact, and thus can play an anti-slip effect when the user's feet are placed on the plastic plate 11. In addition, in order to facilitate production and processing, the anti-slip bumps 12 and the plastic plate 11 are integrally molded. When in use, through the cooperation of the U-shaped fixing rod 9 and the footrest 10, when the user sits on the toilet chair, the footrest 10 provided can support the user's feet, and as shown in the figure, the footrest 10 will not fall again after being rotated and dropped, thereby playing the role of foot support, and when the footrest 10 is used, it can be rotated and folded.
