Next to the desktop book grid (12) a desktop rotating part (13) is installed, and one end of the desktop rotating part (11) is provided with an inverted U-shaped groove, and the other end is provided with a bending device. The desktop (13) is connected, and the inverted U-shaped groove of the desktop rotating part (11) is buckled on the desktop frame (10) of the fixed mount (7). The front lower part of the gear is connected, and due to the effect of the desktop rotating part, the desktop can be turned upwards by 90 degrees.

Referring to Fig. 6, the fixed frame (7) is a rectangular frame member, and its left and right sides are respectively two straight rails with a T-shaped section, and the middle of the two straight rails is connected by two upper and lower hook connecting plates (25) to form a whole . In the middle of every hook connecting plate, two hooks are arranged, that is, the upper hook (5) and the lower hook (9), and the hook is hung on the pasting board cross-hanging block (3), and the upper end surface of the fixed mount (7) is installed The upper fastener (4), referring to Fig. 7a and Fig. 7b, the front end of the upper fastener (4) is like a small hoe, the rear end is connected with the upper fastener base plate (22), and the front end of the upper fastener (4) can Rotate up.

Referring to Fig. 8a and Fig. 8b, pasting board is two independent small boards and promptly goes up pasting board (2) and following pasting board (8), and the center of every pasting board is provided with two square holes, outside each square hole A horizontal hanging block (3) is set, the back of the pasting board is pasted on the wall where the table needs to be installed with two double-sided adhesive tapes, and the entire fixing frame is hooked on the pasting board through the upper hook (5) and the lower hook (9) on the horizontal hook (3).

Referring to Fig. 9, the folded book can be made of various materials, such as planks and plastics, and the present embodiment is made of corrugated cardboard. When the table is erected, the upper fastener (4) hooks the edge seal (17) of the desktop, and the desktop is fixed in the fixed frame (7). When using the table, the side legs are rotated upwards to 90 degrees. Fastener (4), the front end of last fastening piece (4) has left the table edge seal (17), and the table just can be put down and used.

Example

The thickness of the corrugated cardboard used in the foldable desk in this embodiment is 3MM. According to the structural characteristics of each part of the desk, it is pasted by three or more layers, and folded into a certain angle at the edge. When bending, the length of the outer ring is greater than the length of the inner ring. The feature keeps the angle after pasting unchanged and greatly increases rigidity and overall strength.

The fixing frame is composed of two straight bars with a T-shaped section on the left and right, pasted by two upper and lower hook connecting plates in the middle, and the upper fastener and the desktop fixing frame are respectively pasted on the upper and lower sides. The front section of the upper fastener is like a hoe. The end is connected with the bottom plate of the upper fastener, and there is a certain angle between the bottom plate and can be rotated freely. Since the upper fastener is heavy in the front and light in the rear, the upper fastener can be tightly attached to the bottom plate of the upper fastener by using its own weight. The function can make the upper end of the table top firmly fastened by the upper fastener when the desktop is erected. Since the bottom edge of the upper fastener is an inclined plane, the upper fastener can be easily pushed open when the side legs are turned upward. Two groups of hooks are respectively arranged in the upper and lower hook connecting plates, which are used to hook the pasting board pasted on the wall. The desktop fixing frame is used for cooperating with the desktop rotating part so that the desktop and the fixing frame form an integral body.

The desktop part is made up of desktop, side feet, desktop rotating parts, side foot rotating parts, desktop book case and side foot book case. The desktop is pasted with three layers of corrugated paper, and the two long sides of the desktop are bent at 90 degrees and 45 degrees to form reinforcing ribs, and a desktop edge seal is installed at one end. The two vertical sides of the side legs are folded into the same shape as the desktop reinforcing rib so that the side legs can be close to the desktop when the desktop is upright so as to reduce the size.

The side foot book grid is installed at the lower end of the side foot. The side foot book grid is a three-sided frame with a bottom plate. The space formed by the two vacant sides can be used to store books and other items.

The desktop and the side legs are connected by the side leg rotating parts, which are partially pasted by multi-layer corrugated paper, using a new multi-layer board folding process, which is the first case in the multi-layer board rotating structure, its structure and The principle is shown in Figure 5a and Figure 5b. The side leg rotating parts are pasted with three layers of corrugated cardboard, and can be rotated from 180 degrees to 90 degrees. layer and the third layer of the side foot rotating part are glued together. Figure 5a is the state of 180 degrees. The length of the circle is consumed by each rotation point, and the first layer has only one rotation point in essence. The two rotation points shown in the figure are material thickness rotation points. Due to the material thickness, one rotation point cannot rotate the plate to 180 degrees. The second layer and the third layer each have three rotation points, the top one of the three rotation points is shared by the angle rotation point and the consumption rotation point, and the other two are consumption rotation points. The principle is that the length is changed after bending, and the rotation The space between the dots must not be pasted and the rest should be pasted with high-quality glue under pressure. In the bending process of the multi-layer plate, the number of layers of the plate can be determined according to needs, and the more the number of layers, the greater the strength. Paste the desktop connection surface (29) on the desktop as shown in Figure 5a, and paste the side foot connection surface (33) on the side foot simultaneously.

The other end of the desktop is provided with a second rotating part which is the desktop rotating part. The structure and working principle of the desktop rotating part are shown in Figure 4a and Figure 4b. The desktop rotating part is a component that rotates from 90 degrees to 180 degrees. It is also made of three layers of corrugated cardboard. Its working principle is the same as that of the side foot rotating part. It’s just that after the rotation, the rotation points of each layer are on a plane (the rotation points of the side leg rotation parts are on a 45-degree oblique line), so the middle layer, the second layer of this case, needs four rotation points, of which the top One is the angle rotation point, and the other three are consumption rotation points, and there are some differences in the peripheral structure. The desktop rotation part has only one connection surface, that is, the connection surface (39) with the desktop. The lower end of the desktop rotation part is provided with an inverted U-shaped Groove, the groove is buckled on the desktop frame of the fixed frame, so that the desktop can be laid flat or rotated 90 degrees upwards, and a hook-shaped boss is designed outside the U-shaped groove to store mobile phones, pens, etc. thing.

A desktop book grid is installed on the top of the desktop rotating part. The desktop book grid is like a dustpan, buckled upside down on the long ribs on the back of the desktop, and forms a large space between the desktop and the desktop, which can store laptops and iPads. , books, etc.

Referring to Fig. 10a, multiple grooves are provided on both sides of the fixing frame for hanging the storage box. As shown in Figure 10b, the shape of the storage box can be varied to suit the needs of different users.
