Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1~3, in the utility model embodiment, a kind of drawing and pulling type blackboard convenient for wiping, including rear plate body 1
With preceding plate body 2, rear plate body 1, preceding plate body 2 and associated joint members constitute existing drawing and pulling type blackboard, since connecting elements is
The prior art does not repeat them here herein, and the rear surface two sides of the bottom of the rear plate body 1 are symmetrically fixed with first support 11, and first
Bracket 11 extends to the front side of preceding plate body 2, is rotatably equipped with the first transfer roller 3, the foreboard between first support 11 described in two sides
Two sides are symmetrically fixed with second support 21 at the top of the rear surface of body 2, and second support 21 extends to the front side of rear plate body 1, two sides institute
It states and is rotatably equipped with the second transfer roller 4 between second support 21, it is preferred that first support 11 and second support 21 are stainless steel
Material is made, and can effectively guarantee service life, and first transfer roller 3 and the second transfer roller 4 are provided with a wiper rail 5,
