In order to solve the above technical problems, the technical scheme that the utility model is used is：A kind of blackboard, including it is plate body, black Blackboard eraser, the upper and lower ends of the plate body respectively offer the chute along the length direction extension of the plate body, and the blackboard eraser is length Strip, and its shape is adapted with the height of plate body, the upper and lower ends of the blackboard eraser are respectively connected with a rubber roll, the rubber Rubber-surfaced roll wheel can be rolled in chute, so as to drive blackboard eraser to be moved horizontally on plate body, the cunning is in " Ω " shape structure, described The left and right ends portion of plate body upper and lower ends is provided with a limited block for preventing blackboard eraser from sliding, and the limited block and plate body are removable Unload formula connection.

Further, the bottom of the plate body is also fixedly connected with a ledge for chalk on blackboard.

Further, the limited block constitutes for the cylinder by a cuboid and located at cuboid head.

Further, it is provided with external screw thread on the cylinder outer peripheral face of the limited block.

Further, the plate body is provided with the internal thread being adapted with the external screw thread on limited block.

From the above-mentioned description to the utility model structure, compared to the prior art, the utility model has following excellent Point：

1st, a kind of blackboard that the utility model is provided, is combined by using by plate body, blackboard eraser, chute and rubber roll The blackboard of composition so that if the blackboard structure it is simple, it is easy to use while promote blackboard eraser move back and forth on blackboard, just Whole face blackboard can be wiped clean easily, it is practical.

2nd, a kind of blackboard that the utility model is provided, by being provided with one limited block in the left and right ends portion of plate body, Limited block and plate body detachable connection so that can also be to the blackboard eraser while blackboard eraser can be avoided movable from plate body Changed, save use cost.
