[0031] refer to Figures 1 to 10 ,like Figures 1 to 10The folding storage rack shown includes a first platform 10 and a second platform 20. One end of the first platform 10 is open and the bottom surface is provided with an extended first base plate 11. One end of the second platform 20 is open and the bottom surface is provided with an extended second base plate 21. The first base plate 11 and the second base plate 21 are stacked on top of each other and hinged by a hinge shaft 30. The first base plate 11 is provided with an arc groove 12 offset from the hinge shaft 30. The second base plate 21 is provided with a sliding pin 22 adapted to the arc groove 12. When the first platform 10 and the second platform 20 rotate relative to each other about the hinge shaft 30, the sliding pin 22 slides in a fan shape along the arc groove 12, so that the two are changed from being arranged coaxially to being arranged at an angle to each other.

[0032] In the above structure, the arc groove 12 is a 1 / 4 arc, which is used to limit the rotation angle between the first platform 10 and the second platform 20. When placing items normally, the first platform 10 and the second platform 20 are arranged coaxially in a straight line. When it is necessary to install it in a corner as a triangular basket, the first platform 10 and the second platform 20 are rotated so that they are arranged at an angle to adapt to the placement in the corner.

[0033] In this embodiment, the end of the arc groove 12 is connected to a first sliding groove 13 opened along the length direction of the first platform 10, and the end of the first sliding groove 13 is tangent to the end of the arc groove 12; the first base plate 11 or the second base plate 21 is provided with a second sliding groove 23 opened parallel to the first sliding groove 13, and the hinge shaft 30 is adapted to the second sliding groove 23; when the second sliding groove 23 is located on the first base plate 11, the hinge shaft 30 is fixed on the second base plate 21; when the second sliding groove 23 is located on the second base plate 21, the hinge shaft 30 is fixed on the first base plate 11; when the first platform 10 and the second platform 20 are coaxial and close to each other, the first sliding groove 13 is adapted to slide with the sliding pin 22, and at the same time, the second sliding groove 23 is adapted to slide with the hinge shaft 30 to shrink the length of the first platform 10 and the second platform 20; when the first platform 10 and the second platform 20 change from being coaxially arranged to being angled to each other, the hinge shaft 30 rotates on the second sliding groove 23.

[0034] In the above structure, based on the folding function, the first slide 13 and the second slide 23 realize the telescopic function between the first platform 10 and the second platform 20, so that it can be expanded in the length direction as needed, so as to adaptively adjust the storage area according to the placement position.

[0035] In this embodiment, the first slide 13 extends from the first base plate 11 to the bottom surface of the first platform 10, and the second slide 23 extends from the first base plate 11 to the bottom surface of the first platform 10 or from the second base plate 21 to the bottom surface of the second platform 20.

[0036] In the above structure, there is sufficient sliding distance between the first platform 10 and the second platform 20 to improve the telescopic adjustment range.

[0037] In this embodiment, the hinge shaft 30 is located at the center of the first base plate 11 and the second base plate 21.

[0038] The above structure ensures stability during rotation.

[0039] In this embodiment, both the first platform 10 and the second platform 20 are grooves; when the first platform 10 and the second platform 20 approach each other, the first platform 10 enters the second platform 20 through the open end of the second platform 20 and they are nested and superimposed, or the second platform 20 enters the first platform 10 through the open end of the first platform 10 and they are nested and superimposed.

[0040] In the above structure, when retracting and storing, it is preferable that the first platform 10 is nested and superimposed on the second platform 20.

[0041] In this embodiment, the first platform 10 has a third slide groove 24 extending along its length on its groove wall, and the open end of the second platform 20 has a slider 14 adapted to the third slide groove 24; or / and the second platform 20 has a third slide groove 24 extending along its length on its groove wall, and the open end of the first platform 10 has a slider 14 adapted to the third slide groove 24.

[0042] In the above structure, the ability to extend and retract the structure helps to improve the stability of the two components when they are interlocked.

[0043] In this embodiment, the third slide groove 24 is provided with a T-shaped / dovetail groove 241 at one end near the open end; the slider 14 is a T-shaped / dovetail block; the T-shaped / dovetail block enters the T-shaped / dovetail groove 241 through the elastic deformation of the groove wall of the first platform 10 or / and the second platform 20, and then slides by the first platform 10 and the second platform 20 along the length direction, while the T-shaped / dovetail block is misaligned with the T-shaped / dovetail groove 241 to prevent it from falling off.

[0044] In the above structure, by squeezing or stretching the open ends of the first platform 10 and the second platform 20, the T-shaped / dovetail block is inserted into the T-shaped / dovetail groove 241, and then the T-shaped / dovetail block slides along the third slide groove 24 and is offset from the T-shaped / dovetail groove 241 to avoid accidental dislodgement; it should be noted that the positions of the third slide groove 24 and the slider 14 can be interchanged on the first platform 10 and the second platform 20.

[0045] In this embodiment, when the first platform 10 and the second platform 20 are arranged at an angle to each other, the angle between them can be adjusted from 0 to 90 degrees.

[0046] In the above structure, the included angle between the two is preferably 90 degrees, which is convenient for adapting to the angle of the wall.

[0047] In this embodiment, both the hinge shaft 30 and the sliding pin 22 are provided with anti-detachment heads 31.

[0048] In the above structure, it is prevented from coming out of the arc groove 12, the first slide groove 13 and the second slide groove 23.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
