The following further describes the present invention through specific embodiments with reference to the accompanying drawings. These embodiments are only used to illustrate the present invention, and are not intended to limit the protection scope of the present invention.

A Rubik's cube rotating cabinet as shown in FIG. 1, which includes: a base (1), a box hinge (3), a rotating mechanism (5), a hinge (4), a handle (6), and a box hinge (3) It is a cube structure (or a cuboid structure) with one side open; the structure of the base (1) is shown in Figures 2 and 3, the first side of which is facing the ground, and a mobile device (pulley, etc.) is used on the ground The three sides of the box (3) are placed on the second side of the base (1), and there are 4 boxes (3) on each layer. In the closed state of the Rubik's cube rotating cabinet, the openings of each layer of boxes (3) are opposite to each other, and the opening directions of adjacent two layers of boxes (3) in the same row are different by 90 degrees.

As shown in Figure 4, two adjacent box hinges (3) on each floor are connected by hinges (4), so there are a total of 4 hinges (4); the first side of any box hinge Hinges are set on the side and the second side respectively. The first side is the side close to the center of this floor when the box opening is closed, and the second side is located next to the opening. The side of the combined contact, the second side is opposite to the first side, and the second side is the side of the box opening that is exposed to the outside when the Rubik's cube rotating cabinet is closed.

A rotation mechanism (5) is provided between the two adjacent boxes (3), so that the box (3) can rotate with the rotation mechanism (5) as an axis, and can rotate up to 180 degrees; The rotating mechanisms are all set on the same straight line perpendicular to the ground; here, the four boxes (3) on each floor correspond to the four quadrants, and the top of each box (3) is equally divided. 4 quadrants; then, the bins in column ABCD correspond to the first to fourth quadrants of each layer, and the rotation mechanism (5) of each bin in column A is set in the third quadrant of a single bin; each bin in column B The rotating mechanism (5) of each box is set in the first quadrant of a single box, the rotating mechanism (5) of each box in column C is set in the first quadrant of a single box, and the rotating mechanism (5) of each box in column D is set ) Is set in the fourth quadrant of a single bin.

When the rotating cabinet is closed, the middle box (3) is exposed on two of the sides, and handles (6) are respectively provided to facilitate the rotating box (3). On these sides provided with a handle (6), hinges (4) are not provided at the same time.

The second surface of the base (1) is provided with 4 slide rails (2), on which a first box (3) is placed; the slide rails (2) include slide rails (21) and slide rails (22); The slide rail slide (22) is a strip-shaped structure, one end of which faces the center of the base (1) and the other end faces the corners of the base (1); the slide rail guide (21) is arranged inside the slide slide (22), Furthermore, a rotation mechanism (5) is slidably arranged on the first layer of the box (3) so that the first-layer box combination (3) can rotate around the rotation mechanism (5) and move along the slide rail (21) with the rotation mechanism (5).

A first embodiment of the present invention is shown in FIG. 5. In this embodiment, upper, middle, and lower three-layer boxes are used, and the four rows are A, B, C, and D. Among them, the rotation between the upper and middle boxes is taken as an example. When the Rubik's cube rotating cabinet is closed, the upper box structure is opposite to the opening of the A box and the C box, and the B box and the D box. The openings of the rows of boxes are oppositely arranged. The middle-level box structure is opposite the openings of the rows of A and B, and the openings of the rows of C and D.

The hinges on the upper level of the A-box and the C-boxes are close to the center, the A-box and the B-boxes are exposed to the outside, and the D-box and the C-boxes are close to the center. The hinges connected to the D-line bin and the B-line bin are near the center. Because the opening directions are staggered by 90 degrees, the sides of the hinges on the upper and middle boxes are staggered (Figure 6a). The hinges connected to the A-box and the C-box on the middle layer are exposed and the A-boxes are exposed. The hinges connected to the B-box bins are near the center, the hinges connected to the D-box bins and the C-box bins are exposed, and the hinges connected to the D-bin bins and the B-box bins are near the center.

As shown in Figures 5a to 5b, when the rotation of the middle row C box and the D row box are closed, the angle between the openings changes from 0 degrees to 180 degrees (Figure 5a corresponds to 30 degrees unfolded, and its top view The effect is shown in Figure 6a; Figure 5b corresponds to a 90-degree expansion, and its top view is shown in Figure 6b.) The hinge connects the A-box and the B-box, and connects the C-box and the D-box. The hinges that move from inside to outside are hinges that connect the A-box and the C-boxes, and the hinge that connects the B-box and the D-boxes move from the outside to the inside; the upper part of each box in the middle The set rotating mechanism drives the boxes in the same row in the upper direction to rotate in the opposite direction. In this process, the upper box connects the hinges of the A box and the B box, and connects the C box and the D box. The hinges move from the outside to the inside, and the hinges connecting the A-box and the C-box, and the hinges connecting the B-box and the D-box are moved from the inside to the outside. When the opening is 90 degrees, the middle box and the upper box appear in a cross shape in the same direction. At this time, due to the misalignment of the rotating mechanism, there is a misalignment in the front-rear direction between the middle layer and the upper box.

As shown in FIG. 5c, when the rotation of the middle row C box and the D row box are closed, and the angle between the openings is 180 degrees, the top view is shown in FIG. 6c. At this time, the middle-level box and the upper-level box are each formed into a rectangular structure, but due to the dislocation arrangement of the rotating mechanism, the middle-level box and the upper-level box are not only displaced in the front-back direction but also in the left-right direction. And the openings of the boxes on each floor are oriented outward, realizing the function of the display cabinet, and the visual effect is good when opened and closed.

When closed or at various unfolding angles, the opening and hinge arrangement and moving method of the lower box are the same as those of the upper box.

The invention is not limited to the foregoing specific embodiments. The invention extends to any new feature or any new combination disclosed in this specification, and to any new method or process step or any new combination disclosed.

Although the content of the present invention has been described in detail through the above preferred embodiments, it should be recognized that the above description should not be considered as limiting the present invention. Various modifications and alternatives to the present invention will be apparent to those skilled in the art after reading the foregoing. Therefore, the protection scope of the present invention should be defined by the appended claims.
