Abstract

一种教师用磁力直尺,其特征在于包括刻度直尺、磁力吸铁部分,并且在塑料直尺两端或内部装有小磁铁。它克服了普通直尺在黑板(铁质)上画线易歪斜且费力的现象,并充分考虑到使用者(教师)对直尺的要求,采用直尺两端加装磁铁方式,增强直尺与黑板的吸附力。通过以上思路实现了根据使用者(教师)的授课特点,增强了直尺的实用性,更加体现出人性化。

Description

教师用磁力直尺
技术领域
教师用直尺在黑板(铁质)上教学领域。 
背景技术
目前教师在黑板(铁质)上用普通直尺画长直线经常会产生歪斜又费力。 
发明内容
现在教师塑料直尺单纯采用塑料为原料。本实用新型专利是一种教师用磁力直尺,其特征在于包括刻度直尺、磁力吸铁部分,并且在塑料直尺两端或内部装有小磁铁。使用传统的教师用直尺,教师用直尺在黑板(铁质)上画长直线时,经常会产生直尺滑动,而产生所画直线歪斜现象。通过本实用新型专利的改进,使直尺借磁力而贴服于黑板表面并不易产生滑动,画直线变的很轻松,从而提高教师画线效率,还能起到节省教师体力的作用。并可以把几把直尺同时使用,从而增加了教学手段。 
附图说明
下面结合附图和实施例对本实用新型进一步说明。
      图1是本实用新型的外观示意图。
图中 1.小磁铁(同2的厚度相同),2.有公制刻度塑料直尺
具体实施方式
      在图1中,在有公制刻度塑料直尺2的两端钻与小磁铁1直径相同的孔,然后把小磁铁1用胶粘合固定在有公制刻度塑料直尺2所钻的孔中。
创新之处: 
本项实用新型专利为一种实用直尺,它克服了普通直尺在黑板(铁质)上画线易歪斜且费力的现象,并充分考虑到使用者(教师)对直尺的要求,采用直尺两端加装磁铁方式,增强直尺与黑板的吸附力。通过以上思路实现了根据使用者(教师)的授课特点,增强了直尺的实用性,更加体现出人性化。
