Detailed Implementation

[0022] like Figures 1 to 4 As shown, a foldable toilet chair with wheels includes a main body 1, which includes a lid support 10 on which a toilet seat 11 is mounted. Push rod supports 20 are movably mounted on both sides of the lid support 10, and these supports can be folded or unfolded relative to the lid support 10. Rear leg supports 30 are movably mounted on the rear ends of both sides of the push rod supports 20. Through folding joints at the connection points, the rear leg supports 30 can rotate around the push rod supports 20, switching between folding and support functions. Armrest supports 40 are movably mounted on the front ends of both sides of the push rod supports 20. The armrest supports 40 can be folded inwards or upwards as needed, providing lateral support to the user when unfolded. A backrest component 50 is mounted on the upper rear end of the push rod supports 20 to support the user's back in a seated position, improving comfort. Universal wheels 21 are mounted on the lower ends of both sides of the push rod supports 20, giving the toilet chair good directional adjustment capabilities during movement. The lower ends of both sides of the rear leg support 30 are equipped with movable rear wheels 31, which ensure stability during use and ease of movement. In use, both the push rod support 20 and the rear leg support 30 are extended to the working position, forming a stable support frame for the toilet chair body 1. The swivel front wheel 21 and the movable rear wheel 31 land simultaneously, allowing the entire toilet chair to be pushed to the usage position. The user sits on the lid support 10, with the armrest support 40 providing support on both sides after unfolding, and the backrest component 50 providing back support from the rear. For cleaning or waste disposal, the toilet lid 11 can be opened to expose the toilet opening. After use or when storage is required, the push rod support 20 is folded towards the lid support 10 by folding the joints, simultaneously causing the rear leg support 30 to fold forward, folding the toilet chair into a compact structure for easy transport and storage.

[0023] In practical implementation, the cover plate bracket 10 and the push rod bracket 20 are movably connected by a push rod connecting rod 22 via fasteners. The push rod connecting rod 22 can rotate relative to the cover plate bracket 10 and the push rod bracket 20, providing guidance and support for the folding and unfolding of the push rod bracket 20. The push rod bracket 20 and the rear leg bracket 30 are movably connected by a rear leg connecting frame 32 via fasteners. The rear leg connecting frame 32 acts as a folding linkage, ensuring that the rear leg bracket 30 moves synchronously with the push rod bracket 20 when folding or unfolding, ensuring that the overall frame maintains a stable trajectory when changing states. In use, the push rod bracket 20 is rotated outwards and unfolded, causing the push rod connecting rod 22 to drive the push rod bracket 20 to be stably locked in the working position; at the same time, the rear leg connecting frame 32 drives the rear leg bracket 30 to unfold backwards, allowing the rear leg support structure to fully unfold. The unfolded push rod bracket 20, rear leg bracket 30, and cover plate bracket 10 together form a stable triangular support frame, giving the toilet chair body 1 a reliable load-bearing capacity.

[0024] In practical implementation, armrest connectors 41 are fixedly installed at the lower rear ends of the two armrest supports 40. The ends of the armrest connectors 41 are movably connected to folding connectors 42. The folding connectors 42 are fixedly installed on the outside of the push rod support 20. Through the movable connection between the armrest connectors 41 and the folding connectors 42, the armrest supports 40 can rotate around the folding connectors 42 to achieve upward folding or inward folding, thereby significantly reducing the lateral width of the entire toilet chair when not in use or when it needs to be stored.

[0025] In practical implementation, the upper rear end of the push rod bracket 20 is symmetrically provided with backrest connecting parts 23 on both sides, and the backrest component 50 is symmetrically provided with backrest connecting rods 51 on both sides. The two backrest connecting rods 51 are correspondingly inserted into the two backrest connecting parts 23, thus allowing the backrest component 50 to be detachably installed on the upper rear end of the push rod bracket 20. This plug-in structure makes the backrest component 50 easy to assemble and disassemble, facilitating transportation, storage, or configuration according to different usage needs. In use, the backrest connecting rods 51 are inserted into the corresponding backrest connecting parts 23, securing the backrest component 50 firmly in place on the upper rear end of the push rod bracket 20, providing back support for the user. When the user sits on the cover bracket 10, the backrest component 50 effectively supports the lower back, improving posture stability and making toileting or nursing procedures more comfortable and safer.

[0026] In practical implementation, a first limiting rod 33 is movably connected between the middle of the cover plate bracket 10 and the rear leg bracket 30. The first limiting rod 33 provides central support when the rear leg bracket 30 is unfolded, and its movable connection allows it to rotate or retract synchronously with the folding action. A second limiting rod 34 is movably connected between the rear of the cover plate bracket 10 and the rear leg bracket 30. The second limiting rod 34 is positioned closer to the rear edge of the cover plate bracket 10 and provides a second support point for the rear leg bracket 30 when the toilet chair is in the unfolded state. Together with the first limiting rod 33, it forms a triangular stable structure, thereby improving the overall load-bearing capacity and lateral stability.

[0027] In practical implementation, push handles 24 are installed at both ends of the push rod bracket 20. The push handles 24 are used by caregivers or users to push the toilet chair when it is moved. The outer surface of the handles can be covered with a non-slip coating to improve grip stability and reduce fatigue during long-term operation. Armrest pads 43 are installed on the two armrest brackets 40. The armrest pads 43 are made of soft material and cover the upper surface of the armrest brackets 40, providing comfortable arm support when the user sits down or gets up, and preventing the metal bracket from directly contacting the skin and causing discomfort.

[0028] In practical implementation, a brake handle 25 is installed at the front end of the push handle 24. The brake handle 25 is used to control the braking of the entire toilet chair. Its position allows caregivers to operate it with one or both hands, improving safety during movement. A brake bracket 35 is installed at the upper end of the movable rear wheel 31. A brake cable 251 connects the brake handle 25 and the brake bracket 35. The brake cable 251 can be made of steel wire core with good force transmission and durability. When the brake handle 25 is squeezed, the brake cable 251 pulls the brake bracket 35 backward, putting the movable rear wheel 31 into a braking state. When the brake handle 25 is released, the brake bracket 35 releases the brake under the action of the reset structure, allowing the movable rear wheel 31 to resume free rolling.

[0029] In practical implementation, toilet seat brackets 12 are symmetrically arranged on both lower sides of the toilet seat bracket 10. A toilet 60 is placed on the toilet seat bracket 12. The toilet 60 and the toilet seat 11 are correspondingly arranged, that is, when the toilet seat is unfolded, the upper opening of the toilet 60 is coaxially aligned with the lower cover of the toilet seat 11, so that the user can directly guide excrement into the toilet 60 when sitting on the toilet. When the toilet seat 11 is open, it provides a passage for toileting, and when closed, it can cover the upper opening of the toilet 60, preventing odor leakage and improving the cleanliness of the usage environment.

[0030] In practice, the lower ends of the two sides of the push rod bracket 20 are provided with pedal connecting parts 26. The outer sides of the two pedal connecting parts 26 are respectively foldable and connected with folding foot pedals 27. When using the toilet chair, the user can unfold the folding foot pedals 27 as a support pedal to facilitate getting on and off the toilet chair. When not in use, the folding foot pedals 27 can be folded up to reduce the overall space occupied and facilitate storage and movement.

[0031] In summary, this utility model's foldable toilet chair with wheels achieves flexible folding and unfolding through a multi-point folding and connection structure of the push rod bracket 20, rear leg bracket 30, and lid bracket 10. The armrest bracket 40 and folding footrest 27 can be adjusted or folded away according to usage needs to save space. The backrest component 50 is detachable, providing comfortable back support for the user. The omnidirectional front wheel 21 and movable rear wheel 31, combined with a braking system, enable convenient movement and fixing. The toilet lid 11 and toilet 60 are correspondingly arranged, allowing the toilet chair to have complete toilet functions when unfolded. This design not only improves user comfort and safety but also facilitates transport, storage, and maintenance through folding and disassembly functions.
