Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention will be combined to clearly and completely describe the technical solutions of the embodiments of the present invention.
As shown in fig. 1 to 4, the present invention provides a sliding blackboard eraser, which is installed on a blackboard 1 and includes a first rail 2 and a blackboard eraser body 4; the first track 2 is arranged on the upper edge of the blackboard 1;
the inner side of the first track 2 is a barb type slide rail; the blackboard eraser main body 4 comprises a blackboard eraser erasing body 41 and a blackboard eraser shell 42, one side of the blackboard eraser erasing body 41 is fixedly connected with the blackboard eraser shell 42, and the other side of the blackboard eraser erasing body is tightly attached to the surface of the blackboard 1; one end of the blackboard eraser shell 42 is fixedly connected with a mounting plate 5, a roller 6 is arranged on the mounting plate, and the roller 6 is hooked in the barb type sliding rail of the first rail 2 and is in sliding connection with the barb type sliding rail;
when the blackboard eraser body 4 wipes the blackboard 1, the roller 6 slides in the barb type sliding rail of the first rail 2, and the blackboard eraser body 4 drives the blackboard eraser erasing body 41 to move transversely relative to the blackboard 1 to wipe.
Further, the lower edge of the blackboard 1 is provided with a second rail 3, a concave chute 301 is arranged on the second rail 3, and the bottom end of the blackboard eraser shell 42 is positioned in the concave chute 301 and does not contact with the concave chute 301.
Further, the magnetic strips 302 are arranged on the bottom surface of the inner cavity of the concave chute 302 and the lower edge of the blackboard eraser shell 42, and the magnetic poles of the opposite surfaces of the two groups of magnetic strips 302 are homopolar, so that when the blackboard eraser shell 42 is used and slides relatively, homopolar repulsion force exists between the two groups of magnetic strips 302, the blackboard eraser shell 42 is slightly lifted upwards, the friction force between the roller 6 and the first track 2 is reduced, and the bottom end of the blackboard eraser shell 42 which is not in contact with the concave chute 301 is matched so as to greatly reduce noise emitted by the blackboard eraser main body 4.
