Detailed Description

The utility model is further described with reference to the following drawings and detailed description.

Example one

As shown in fig. 2, 3, 4, 5 and 6, the lifting whiteboard comprises a whiteboard 1 and a bracket provided with two upright posts 2. Be equipped with first corner cover 3 on 1 lower extreme two corners of blank respectively, be equipped with the bellying 30 that is close to stand 2 on the first corner cover 3, bellying 30 and stand 2 contact.

The side of the white board 1 is respectively provided with a wrapping 11, and two ends of the wrapping 11 are provided with connecting holes 110. The first corner sleeve 3 is connected with the side edge covering 11 and the lower end edge covering of the whiteboard 1, two connecting columns 31 are arranged on the first corner sleeve 3, the axes of the two connecting columns 31 are perpendicular to each other, and the two connecting columns 31 on the first corner sleeve 3 are respectively inserted into the connecting holes 110 of the two adjacent edge covering 11. Two corners at the upper end of the white board 1 are respectively provided with a second corner sleeve 4, the second corner sleeves 4 are connected with the side edge covering edge 11 and the upper end edge covering edge of the white board 1, and the second corner sleeves 4 are not provided with a mechanism which is in contact with the stand column 2.

The rear end of the first corner sleeve 3 is provided with a rear plate 32, the rear plate 32 is provided with a right-angled triangle plate 33, the right-angled end of the right-angled triangle plate 33 is connected with the rear plate 32, and two acute-angled ends of the right-angled triangle plate 33 are provided with backward folded edges 331. After the first corner sleeve 3 is connected with the whiteboard 1, the front surface of the right-angle triangle 33 is attached to the back surface of the whiteboard 1, and the folded edge 331 plays a role in guiding when the first corner sleeve 3 is inserted.
