Detailed Description

The utility model will be further described with reference to specific embodiments, and the advantages and features of the utility model will become apparent as the description proceeds. These examples are illustrative only and do not limit the scope of the present invention in any way. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model, and that such changes and modifications may be made without departing from the spirit and scope of the utility model.

Referring to fig. 1 and 2, the utility model relates to an angle-adjustable reading and writing board, which comprises a lower board 1, an upper board 2 and an angle adjusting mechanism, wherein the upper board 2 is connected with the lower board 1 through a hinge, the angle adjusting mechanism comprises a fixing nut 3, a screw rod 5, a handle 6 and a rubber sleeve 4, the fixing nut 3 is fixedly installed on one side of the upper part of the lower board 1 through a screw, and the screw rod 5 is arranged along the vertical direction and assembled with the fixing nut 3; the lower end of the screw is provided with the handle 6, and the upper end is sleeved with the rubber sleeve 4; the screw 5 is lifted, so that the included angle between the upper plate 2 and the lower plate is continuously adjusted within the range of 90-180 degrees; two folding support rods are arranged on the back of the lower plate 1, and when the folding support rods are opened, the lower plate 1 and the horizontal direction form an included angle of 10 degrees (refer to the national standard angle of a desk, which is beneficial to reading and writing); the screw rod is lifted and descended by rotating the holding handle.

The hinge be hinge 7, hinge 7 be two, two hinge 7 along fixation nut 3 symmetry setting.

As shown in fig. 2, the upper plate 2 is far from the lower plate 1, and when the upper plate is in a turned-over state, the rubber sleeve 4 is pressed against the upper plate 2 to support the upper plate 2.

As shown in fig. 1, when the upper plate 2 is placed close to the lower plate 1 and is stacked on the lower plate 1, the inner surface of the upper plate 2 is adjacent to the lower plate 1, and felt is attached to the outer surface, so that writing or drawing can be performed on the felt without opening the upper plate.

The upper plate 2 is close to the lower plate 1, when the upper plate and the lower plate 1 are overlapped together, the inner side surface (back surface) of the upper plate 2 is adjacent to the lower plate 1, and felt is compounded on the outer side surface (front surface); and the inner side surface (front surface) of the lower plate 1 is compounded with felt.
