Abstract

本实用新型公开了一种带压簧的直尺，它与量具有关，它方便使用操作得力，无需预留刀口差，其技术方案的内容如下：它包含长条形的尺体，在靠近尺边一侧加工有数个横向束口销孔，每个销孔内都装置有一个端头加粗的销杆，销杆外端都从销孔伸出且套有一压簧同时又与一个横截面为方形的尺杆连接。本设计适用于裁划玻璃用的直尺。

Description

带压簧的直尺
技术领域：
本实用新型与量具有关，具体是指带压簧的直尺。 
背景技术：
将整块的玻璃裁划为较小的形状需用到直尺，广见的加工玻璃场所所用的直尺一般为长条形，使用操作时一般用左手按在测量好后确定的位置然后右手持杆形玻璃刀靠住尺边划线，由于杆形玻璃刀的较特殊造型，其刀刃尖距尺边存在一个2-3mm的间隔距离，刀尖在玻璃表面的划线位置因此并不就是这种长条形直尺的边口位置而是稍往外2-3mm，而直尺的边口相对于尺体来说都是整体的一个，不能作相对移动，人们惯常的做法便是在裁划前的测量时需要留出这个刀口差，裁划玻璃的操作者十分希望有一种无需预留刀口差的直尺。 
发明内容：
本实用新型的目的便是提供一种直尺的新的技术方案即带压簧的直尺，它可以解决上述不便。 
本实用新型技术方案的内容如下：它包含长条形的尺体，在靠近尺边一侧加工有数个横向束口销孔，每个销孔内都装置有一个端头加粗的销杆，销杆外端都从销孔伸出且套有一压簧同时又与一个横截面为方形的尺杆连接。 
本实用新型的有益效果是测量直接明了，无需预留刀口差。 
附图说明
图1为直尺的俯视图。图2为直尺销孔部位的横截面视图。 
各图中，1为尺体，2为销孔，3为压簧，4为销杆，5为尺杆。 
具体实施方式：
如图1、图2所示，在长条形的尺体1的靠近尺口边一侧(即前侧)加工有数个横向的束口销孔2，每个销孔内都装置有一根端头加粗的销杆4，销杆外端都从销孔伸出且共同与一个横截面为方形的尺杆5连接成一体，同时在销杆上套有一压簧3，尺杆5连同销杆4横向的弹性活动量设计为杆形的玻璃刀刀尖到刀头一侧(也即到尺边)的距离(约2.5mm)，也就是刀口差的大小，由于销杆的后端头加粗，在置于束口的销孔内后便会在横的方向上被束口控制(束口部位的加工可采用粘结的方式实现)，只能有限度的活动，同时销杆4又可以保证尺杆5与尺体1在纵向上的整体一致性，不会在划线时发生相对移动，而销杆上穿套的压簧3的弹性力会使其在无外力作用下始终处于最向外的位置，当受到横向外力的挤压后比如玻璃刀刀头的挤压，尺杆5连同销杆4便向后压缩压簧3，促使尺杆5靠住尺体1的尺边，此时尺杆由前向后横向移动的距离就是杆形的玻璃刀刀尖到尺边的距离，这样玻璃刀尖划线的位置也就是最初量得的所裁划玻璃成品的需要尺寸，无需再考虑或加或减刀口差了。
