Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, a blackboard for teaching convenient to fold, including outer frame 1 and spacing groove 2, the equal opening of the upper and lower extreme of the inside of outer frame 1 is provided with spacing groove 2, equal vertical the inserting of right side below and the upper right side of outer frame 1 is equipped with spacing bolt 3, the embedding of positive surface left side of outer frame 1 is provided with left clipboard 4, the back fixed mounting of left clipboard 4 has corrosion resistant plate 401, the equal fixed mounting in the upper right side and the right side below at the 4 back of left clipboard has hinge 5, the right side fixed mounting of two hinges 5 has right clipboard 6, the back fixed mounting of right clipboard 6 has rubber slab 601, the equal fixed mounting of the upper and lower extreme on left clipboard 4 and the upper and lower extreme on right side of right clipboard 6 has spacing post 7, the inside of spacing post 7 all rotates and is connected with universal wheel 701, the equal embedding in top of left clipboard 4 and right clipboard 6 is provided with hidden handle 8.

In this embodiment, be the symmetry setting around hinge 5's vertical axis between left clipboard 4 and the right clipboard 6, left clipboard 4 and right clipboard 6 rotate around hinge 5's the end about respectively 90, rotate through promoting left clipboard 4 and right clipboard 6 and hold about hinge 5 for the left clipboard 4 and the right clipboard 6 collapsible accomodating of hinge 5 left and right ends are in the same place.

In this embodiment, the position of the left writing board 4 and the right writing board 6 in the outer frame 1 can be adjusted by pushing the left writing board 4 and the right writing board 6 to slide in the limiting groove 2 when the limiting posts 7 of the left writing board 4 and the right writing board 6 are just embedded in the limiting grooves 2 arranged at the upper end and the lower end of the outer frame 1 and the left writing board 4 and the right writing board 6 are embedded in the limiting grooves 2 of the outer frame 1.
