Abstract
The utility model discloses a frameless writing board which an upper faceplate and a lower faceplate. The upper faceplate and the lower faceplate are symmetrically distributed, the middle parts thereof are respectively sunken to form large faceplates, and U-shaped flanged edges which project upwards and have opposite opening directions are respectively formed on the peripheries of the upper faceplate and the lower faceplate; and the U-shaped flanged edges formed by butt-jointing the upper faceplate and the lower faceplate together are buckled together through U-shaped clipping strips. Fillers adopt any foaming plates, honeycomb card boards and corrugated boards and are arranged between the large faceplates of the upper faceplate and the lower faceplate. The upper faceplate and the lower faceplate are formed through being pressed and produced in a press forming manner and have simple structure, low material cost and more convenient installation. In addition, the frameless writing board has the advantages of more stable structure and longer service life.
Description
Technical field
The utility model belongs to the teaching equipment technical field, particularly a kind of no frame board.
Background technology:
