Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a portable support seat of this utility model includes a U-shaped frame 1, a seat plate 3, and a backrest 2. The U-shaped frame 1 forms a rectangular groove inside. The backrest 2 and the seat plate 3 are arranged one above the other in the rectangular groove. A limiting part 6 protrudes from the opening at the end of the rectangular groove away from the backrest 2. The two sides of the backrest 2 are bent to form fixing parts. The fixing parts abut against the limiting parts 6. Each fixing part is equipped with a limiting mechanism to fix the seat plate 3 to the U-shaped frame 1. One end of the rectangular groove is provided with an inclined placement surface 11. Rotation mechanisms connected to the U-shaped frame 1 are installed on both sides of the backrest 2.

[0023] In this embodiment, the limiting mechanism includes a push plate 4, multiple positioning rods, and multiple compression springs 7. The fixed part is provided with multiple shaft holes. The two sides of the rectangular groove are provided with first positioning holes directly opposite the shaft holes. The two sides of the rectangular groove are provided with second positioning holes 8 above the first positioning holes. The push plate 4 is provided inside the fixed part. One end of the push rod extends to the outside. One end of the positioning rod is installed on the push plate 4, and the other end passes through the shaft hole and is inserted into the first positioning hole. The compression springs 7 are all sleeved on the positioning rods. One end of the compression springs 7 is installed on the push plate 4, and the other end is installed on the fixed part.

[0024] In this embodiment, the rotating mechanism includes a bearing and a shaft 9. The bearing is embedded in the side of the backing plate 2, and one end of the shaft 9 is installed in the inner ring of the bearing, while the other end is installed in the U-shaped frame 1.

[0025] In this embodiment, a handle 5 is installed at one end of the U-shaped frame 1, so that the device can be carried directly by holding the handle.

[0026] In this embodiment, a space is formed between one end of the seat plate 3 and the U-shaped frame 1 to allow the seat plate 3 to rise smoothly until it is flush with the upper surface of the U-shaped frame, thus avoiding being blocked by the backrest after it is opened.

[0027] In this embodiment, the upper surface of the backing plate 2 is flush with the outer surface of the U-shaped frame 1, which increases the flatness of the surface and allows for better stacking and carrying.

[0028] In this embodiment, magnets 10 are embedded in both sides of the rectangular groove, and metal sheets are embedded in both sides of the backing plate 2. The metal sheets are all magnetically attracted and fixed by the magnets 10. The stability of the backing plate after it enters can be ensured by magnetic attraction.

[0029] As attached Figure 4 As shown, when in use, lift the backrest upwards to open it around the axis until one side of the backrest rests against the placement surface, tilting the backrest to better conform to ergonomics. After the backrest is no longer obstructed, first pull the positioning rod outwards using the push plate to pull it out of the first positioning hole, and then lift the seat plate upwards. After the surface of the seat plate is flush with the surface of the U-shaped frame, the positioning rod can be positioned opposite the second positioning hole. After releasing the push plate, the return energy of the compression spring will insert the positioning rod into the second positioning hole to ensure the flatness of the seat plate surface, allowing for better sitting on the seat plate and U-shaped plate, while the back can rest on the backrest.

[0030] When not in use, the positioning rod can be pulled out again, and the base plate can be moved downwards so that the fixed part on the base plate abuts against the limiting part. At this time, the positioning rod can be inserted into the first positioning hole, and as the base plate moves downwards, space can be made above the base plate for the backing plate to enter, allowing the backing plate to rotate into the rectangular groove and be attracted and fixed by the magnet. After the backing plate enters the rectangular groove, the backing plate and the U-shaped plate can be combined to form a relatively flat plate, so that the device can be stacked together and is convenient to carry.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
