Abstract

The utility model relates to a new blackboard groove, which comprises a groove body, wherein the groove body is positioned at the rear end of a blackboard, and forms an angle of 30 DEG with the blackboard, and one end of the groove body, which is away from the 30-degree angle, is coupled with a blocking cover; a hook is arranged on one side of the blocking cover, which is away from the groove body; and a hanging ring is arranged in the position of the groove body, which is corresponding to the hook. When in use, particularly when writing on the blackboard, the chalk powder falls into the groove body, moves downwards in the groove body under the action of the gravity, and deposits at the part of the groove body, which is close to the blocking cover, then, the powder can be easily cleaned up through taking out the hook from hanging ring. The blackboard groove has the advantages of simple structure, convenient use, reasonable structure, etc., and effectively solves the problem that the chalk powder deposited in the prior blackboard groove cannot be cleaned up easily.

Description

The new blackboard groove

Technical field the utility model relates to a kind of auxiliary device of blackboard, especially a kind of new blackboard groove.

The existing blackboard groove of background technology all is the parallel bottom that places blackboard, and the powder of chalk directly drops in the blackboard groove, but very difficult existing blackboard groove cleaning chalk powder the time, has brought difficulty to cleaning.

The summary of the invention the purpose of this utility model has overcome above-mentioned said deficiency, and a kind of new blackboard groove is provided, and is used to solve existing blackboard groove problem not easy to clean.

For achieving the above object, the utility model new blackboard groove comprises cell body, and cell body is positioned at the bottom of blackboard, and becomes the angle of 30 degree with blackboard, at the end axle connection door away from 30 degree angles of cell body; And be provided with hook away from the one side of cell body at door; The position corresponding with hook at cell body is provided with link.

After adopting said structure, during use, when on blackboard, writing, the powder of chalk will drop in the cell body, be subjected to the effect of gravity, powder can move downwards in cell body, is deposited in the position of close door in the cell body, to link up with in link then and take out, can light structure ground be cleaned out by powder.

The utility model has the advantages that: simple in structure, easy to use, structure has rationally solved existing chalk powder effectively and has been deposited in the blackboard groove, not the problem of easy to clean.

Description of drawings Fig. 1 is the overall structure schematic diagram of the utility model new blackboard groove.

The specific embodiment as shown in Figure 1, the utility model new blackboard groove comprises cell body 1, cell body 1 is positioned at the bottom of blackboard, and become the angles of 30 degree with blackboard, connect doors 2, and be provided with hook 3 away from the one side of cell body 1 at door 2 at the end axles away from 30 degree angles of cell body 1; Be provided with link 4 at cell body 1 with hook 3 corresponding positions; When writing on blackboard, the powder of chalk can drop in the cell body 1, is subjected to the effect of gravity, and powder can be deposited in door 2 positions in the cell body 1, and the hook 3 of door 2 is taken out in link 4, can like a cork the chalk powder in the cell body 1 be cleaned out.
