[0020] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] Figure 1 , Figure 2 , Figure 3 and Figure 4 A portable cushion is shown, comprising a cushion body 1 filled with sponge, a first hard support frame 2 being arranged on one side of the cushion body 1, and a second hard support frame 3 being arranged on the other side of the cushion body 1, the upper ends of the first hard support frame 2 and the second hard support frame 3 are provided with top connecting frames 4 with mutually staggered layouts, the first hard support frame 2 and the second hard support frame 3 are movably assembled by means of a transverse assembly rod 5 inside the top connecting frame 4, both side walls of the cushion body 1 are provided with lateral protrusions 6 protruding outwards, and embedded elastic locking frames 7 are fixedly assembled on both side walls of the lateral protrusions 6, and both sides of the inner top surface and inner bottom surface of the first hard support frame 2 and the second hard support frame 3 are provided with limit slots 8 matching with the embedded elastic locking frames 7.

[0023] In order to cooperate with the lateral installation limit, strip-shaped fixing grooves for fixing the embedded elastic locking frame 7 are opened on both sides of the lateral protrusion 6.

[0024] In order to cooperate with sliding adjustment and elastic reset, the embedded elastic locking frame 7 includes a side frame 71 fixed inside the strip fixing groove, a telescopic limit block 72 slidably assembled at both ends of the side frame 71, an inner guide rod 73 fixed on the inner side surface of the side frame 71, and an extrusion spring 74 sleeved on the inner guide rod 73.

[0025] In order to cooperate with sliding assembly and control, a side guide through hole matching the inner guide rod 73 is opened inside the telescopic limit block 72, and an outer control groove 75 for convenient control is opened on the outer surface of the telescopic limit block 72.

[0026] The telescopic limit block 72 is slidably assembled inside the side frame 71 by being sleeved on the outside of the inner guide rod 73 through the side guide through hole, and then the telescopic limit block 72 is controlled to extend outward by squeezing the spring 74. People control the sliding adjustment of the telescopic limit block 72 in the side frame 71 by inserting their fingers into the outer control groove 75.

[0027] In order to facilitate the inner storage and support, built-in flip support rods 9 are movably installed inside both sides of the first rigid support frame 2.

[0028] In order to limit and fix the angle between the first rigid support frame 2 and the second rigid support frame 3, a transverse limit rod 10 that cooperates with the built-in flip support rod 9 is fixed on the inner side surface of the second rigid support frame 3, and the built-in flip support rod 9 is connected to the transverse limit rod 10 for limiting by means of an end limit hook 11 that is sleeved on the transverse limit rod 10.

[0029] When it is necessary to unfold, the built-in flip support rod 9 is flipped outward, and then the limit hook 11 at the end is sleeved on the horizontal limit rod 10. At this time, the built-in flip support rod 9 is stuck on the horizontal limit rod 10, which will fix the angle between the first rigid support frame 2 and the second rigid support frame 3, so that a supporting triangle can be formed. Then the lateral protrusion 6 on one side of the cushion body 1 is inserted into the outer opening of the first rigid support frame 2, and then the telescopic limit block 72 is inserted into the outer control groove 75, so that the cushion body 1 will be fixed on the outside of the first rigid support frame 2; and when stored, the telescopic limit The positioning block 72 is separated from the outside control groove 75, and then the cushion body 1 is separated from the first rigid support frame 2, and then the built-in flip support rod 9 is lifted upward so that the limit hook 11 at the end is separated from the horizontal limit rod 10, so that the angle between the first rigid support frame 2 and the second rigid support frame 3 can be adjusted, and the lateral protrusions 6 on both sides of the cushion body 1 are inserted into the outside openings of the first rigid support frame 2 and the second rigid support frame 3, and then the telescopic limit block 72 is inserted into the outside control groove 75, so that the cushion body 1 will be fixed on the inside of the first rigid support frame 2 and the second rigid support frame 3.
