Abstract

紧固螺丝防脱落游标卡尺,涉及一种测量工具。设有尺身、螺钉盖紧定螺钉、游标紧定螺钉、螺钉盖和游标。所述螺钉盖安装在游标紧定螺钉上,所述游标紧定螺钉安装在游标上,所述螺钉盖的两端通过螺钉盖紧定螺钉固定在游标上。螺钉盖紧定螺钉对螺钉盖具有紧固作用,所述游标紧定螺钉的移动范围受螺钉盖的限制而不会脱落。结构简单、使用方便,由于在游标安装螺钉的正上方增加一个螺钉盖,限制螺钉的运动轨迹,防止螺钉的脱落丢失。

Description

紧固螺丝防脱落游标卡尺
技术领域
本实用新型涉及一种测量工具,具体涉及一种紧固螺丝防脱落游标卡尺。 
背景技术
游标卡尺是机械制造业中最常用的量具之一,它主要由尺身以及能在尺身上滑动的游标组成,通过尺身和游标上的刻线间距差及其积累值来细分计数,其结构简单,使用方便。现有技术中,游标上的游标紧定螺钉容易脱落及丢失,给使用者造成许多不便。 
发明内容
本实用新型的目的在于针对现有的游标卡尺游标上的螺钉易脱落丢失的问题,提供一种紧固螺丝防脱落游标卡尺。 
本实用新型设有尺身、螺钉盖紧定螺钉、游标紧定螺钉、螺钉盖和游标。 
所述螺钉盖安装在游标紧定螺钉上,所述游标紧定螺钉安装在游标上,所述螺钉盖的两端通过螺钉盖紧定螺钉固定在游标上。 
螺钉盖紧定螺钉对螺钉盖具有紧固作用,所述游标紧定螺钉的移动范围受螺钉盖的限制而不会脱落。 
与现有的游标卡尺相比,由于本实用新型在游标安装螺钉的正上方增加一个螺钉盖,限制螺钉的运动轨迹,以防止螺钉的脱落丢失。本实用新型无需在现有的游标卡尺上作很大的改变,即能使游标上的螺钉不会脱落丢失。
本实用新型结构简单、使用方便,能够有效预防游标卡尺螺钉脱落丢失等问题。 
附图说明
图1为本实用新型实施例的结构组成示意图。 
图2为图1的俯视图。 
在图1和2中,各标记如下:1-尺身;2-螺钉盖紧定螺钉;3-游标紧定螺钉;4-螺钉盖;5-游标。 
具体实施方式
参见图1和2,本实用新型实施例设有尺身1、螺钉盖紧定螺钉2、游标紧定螺钉3、螺钉盖4、游标5。 
所述螺钉盖4安装在游标紧定螺钉3上,所述游标紧定螺钉3安装在游标5上,所述螺钉盖4的两端通过螺钉盖紧定螺钉2固定在游标5上。 
螺钉盖紧定螺钉2对螺钉盖4具有紧固作用,所述游标紧定螺钉3的移动范围受螺钉盖4的限制而不会脱落。
