[0022] See also Figure 1-Figure 7 , is a structural diagram of a folding toilet chair and some components thereof provided by an embodiment of the present utility model.

[0023] As shown in the figure, the embodiment of the present invention provides a folding toilet chair, which includes a seat frame 1, a main body tube group, a long connecting rod group, a short connecting rod group, a seat plate 5, a support rod 6 and a support piece 7. Among them, the main body tube group includes two main body tubes 2, which are respectively arranged relatively parallel to the front end of the seat frame 1. The bottom ends of the main body tubes 2 are respectively hinged to the front end of the seat frame 1. One end of the support piece 7 is hinged to the main body tube 2 through an indexing pin 8, and the other end of the support piece 7 is hinged to the front end of the seat frame 1. The long connecting rod group includes an indexing pin 8. Two long connecting rods 3 are respectively arranged on both sides of the bottom end of the seat plate 5, and the short connecting rod group includes two short connecting rods 4 respectively arranged on both sides of the bottom end of the seat plate 5. One end of the long connecting rod 3 is hinged to the rear bottom end of the seat plate 5, and the other end is hinged to the main body tube 2. One end of the short connecting rod 4 is hinged to the front bottom end of the seat plate 5, and the other end is hinged to the main body tube 2. The top end of the support rod 6 is hinged to the middle part of the long connecting rod 3 through the flat head pin 9, and the other end is hinged to the rear end of the seat frame 1. The seat plate 5, the long connecting rod 3, the short connecting rod 4 and the main body tube 2 form a linked quadrilateral support structure.

[0024] The indexing pin can be inserted or pulled out by operating a knob at one end, thereby connecting or disconnecting two connected parts.

[0025] The indexing pin and the flat pin are hinged to make the folding toilet chair of the present invention have the effect of being foldable. Figure 6As shown, the connection is released by pulling out the pin by turning the knob at one end.

[0026] In one possible implementation, the support rod 6 is a telescopic push rod, which controls the rotation of the long connecting rod by the extension and retraction of the telescopic push rod, thereby driving the seat plate to flip up or lay flat.

[0027] In the present utility model, the power of the folding toilet chair comes from the telescopic push rod below the rear end of the seat frame. When the telescopic push rod pushes the long connecting rod, one end of the telescopic push rod is hinged to the bottom end of the seat frame, and the other end is hinged to the long connecting rod. When the telescopic push rod is extended, the angle change of the long connecting rod drives the short connecting rod group to rotate forward. One end of the long connecting rod and the short connecting rod are respectively hinged to the bottom end of the seat frame. When the telescopic push rod is extended and pushes the long connecting rod to rotate, the seat frame will form an upward and forward movement at the same time under the hinged cooperation of the two groups of connecting rod groups, thereby achieving the effect of helping the user to stand up or sit slowly in the opposite direction.

[0028] Specifically, the electric telescopic push rod can be extended to push the long connecting rod to drive the short connecting rod to rotate in the same direction. Through the rotational drop between the long connecting rod and the short connecting rod, the seat plate can be flipped up at an angle or laid flat downward, thereby helping the user to stand up or sit down slowly.

[0029] Among them, in a possible implementation, such as Figure 7 As shown, the long connecting rod 3 includes a long tube 31 and a Y-shaped connecting piece 32. The bottom end of the middle part of the long tube 31 is hinged to the telescopic end of the telescopic push rod 6. One end of the long tube 31 is hinged to the rear bottom end of the seat plate 5, and the other end is hinged to one end of the Y-shaped connecting piece 32 through the indexing pin 8. The other end of the Y-shaped connecting piece 32 is hinged to the main tube 2.

[0030] By setting the Y-shaped connecting piece, when the folding toilet chair is folded, the indexing pin switches and penetrates into different holes to achieve locking in the folded state.

[0031] In one possible implementation, the bottom end of the middle portion of the long tube 31 is hinged to the telescopic end of the telescopic push rod 6 via a flat pin 9 .

[0032] Among them, in a possible implementation, the folding toilet chair also includes an armrest tube 10, the rear end of the armrest tube 10 is inserted into the tube hole on the rear end of the seat plate 5, and the front end of the armrest tube 10 is overlapped on the seat plate 5.

[0033] In one possible implementation, support legs 11 are respectively provided around the bottom end of the seat frame 1 .

[0034] The design of the supporting feet can facilitate movement during toileting, and anti-slip pads can be added to the supporting feet to effectively prevent slipping and improve safety of use.

[0035] In one possible implementation, the telescopic push rod 6 is an electric telescopic push rod.

[0036] Based on the structural design of the present invention, the folding process of the folding toilet chair is further described in detail in combination with the drawings in the specification.

[0037] See also Figure 2 When you need to fold the toilet chair, first pull the armrest tube out of the tube hole to both sides along the direction of the arrow in the figure ( Figure 2 A), then place the handrail tube in the hollow of the seat frame ( Figure 2 B) to complete the first step of folding. Then continue to see Figure 3 , remove the flat pins on the upper ends of the telescopic push rods on both sides (i.e. the telescopic ends), turn the telescopic push rods forward and place them to complete the second step of folding. Figure 4 , pull open the indexing pin that fixes the main pipe end of the support plate ( Figure 4 C), and rotate the support piece forward, then rotate the entire upper part of the toilet chair forward and lay it flat ( Figure 4 D) to complete the third step of folding. Finally, refer to Figure 5 , pull open the indexing pin of the Y-shaped connecting piece so that the long connecting rod is folded down to the limit position, loosen the indexing pin, and let the pin of the indexing pin pass through the other hole of the Y-shaped connecting piece, so that the entire toilet chair can be fully folded.

[0038] From the above detailed description of the folding toilet chair in the present invention in combination with the drawings in the specification, it can be understood that the folding toilet chair of the present invention is a quadrilateral support structure composed of a main tube group, a long connecting rod group, a short connecting rod group and a seat plate, and is hinged through a specific structure such as a flat head pin and an indexing pin, thereby realizing the foldability of the toilet chair. Compared with the existing welded one-piece frame toilet chair on the market, the foldable toilet chair of the present invention can be easily disassembled and assembled, reducing the product packaging volume, reducing the product transportation cost, and improving the product portability.

[0039] Secondly, the folding toilet chair of the present invention further controls the rotation of the long connecting rod through the telescopic push rod to drive the seat plate to flip up or lay down flat, thereby assisting people with limited mobility to sit down slowly to use the toilet or stand up slowly.

[0040] In addition, this product is suitable for different toilets, takes up little space, has strong adaptability, has a compact and reasonable structural design, is safe, convenient and quick to use, and greatly increases the safety of users when using the toilet.
