Description

双擦式黑板
本实用新型涉及一种将黑板擦嵌在黑板表面的双擦式黑板。
目前现有的黑板下部有一条较宽的糟,黑板擦较小,可放在糟内,黑板与板擦为分离式,黑板擦常被随意放置而用时找不到,造成许多麻烦,另外用这种黑板擦擦黑板时,粉笔灰仅有一小部分落入下部糟中,造成较大污染。
本实用新型的目的是提供一种可减少粉笔灰的将板擦嵌入黑板表面的双擦式黑板。
为实现上述目的,本实用新型的技术方案是:一种双擦式黑板,其特征在于黑板(1)的上、下边设有槽(2),黑板擦(3)的上下边嵌入槽(2)内,并可沿槽(2)移动,黑板擦(3)上固定有手柄(4)。
本实用新型由于将黑板擦嵌入黑板表面,使之成为一体,因此可避免由于板擦随意放置而造成的麻烦,可随时拉手柄擦黑板,因此更加方便;板擦长度与黑板的宽度相同,擦黑板比小板擦节约时间,粉笔灰受长板擦的限制沿同一方向运动,减少了室内污染,板擦可随时更换。
图1为本实用新型的结构示意图。
下面结合附图对本实用新型的具体实施方式作进一步说明:黑板1的上、下边设有槽2,将黑板擦3的上、下边嵌入槽2内,板擦3正面正对黑板1表面,其背面上固定安装有手柄4,拉动手柄4,板擦3被带动沿着槽2可左右移动,板擦3可根据需要安装1-2个。
