Abstract

普通剪刀因长期磨损,两片刀剪之间会产生一定 间隙,影响正常剪切。本实用新型介绍了一种自紧式 剪刀,它由两片刀剪和一副自紧式铰链构成,自紧式 铰链可以产生一弹性夹持力,夹紧在两片刀剪外侧, 从而消除因磨损而在两片刀剪之间产生的间隙。这 种剪刀使用应手,制造简单,而且成本低。

Description

剪刀是剪切布料和金属板材的必备工具,它由两片刀剪和一付铰链构成,铰链包括一个支承杆和两个垫片。装配时,先将支承杆穿过两片刀剪上对应的孔,再在支承杆两端分别套上一个垫片,而后对支承杆两端进行点铆,使两片刀剪贴紧,同时刀剪又可绕支承杆转动。这种剪刀的缺点是:磨损会引起铰链的松动,使本应贴紧的两片刀剪之间产生间隙,影响正常剪切。本实用新型的目的是要提供一种自紧式剪刀,这种剪刀优于普通剪刀,它没有铰链松动这一缺点,因而,使用应手、寿命长。
本实用新型的目的是这样实现的:自紧式剪刀由两片刀剪和一付自紧式铰链构成。其中,自紧式铰链包括一个支承杆、一个压簧,一个套管和一个垫片。压簧在套管内呈压缩状,其伸张力通过套管以及和支承杆铆连的垫片,以与其本身相反的方向作用在两片刀剪的外侧,使两片刀剪受到一弹性夹持力。当长期工作而出现磨损时,自紧式铰链所产生的弹性夹持力始终作用在两片刀剪的外侧,使两片刀剪紧密相贴,故而操作十分应手。
本实用新型的具体结构由以下实施例及其附图给出。
图1是本实用新型的结构图。
下面结合附图进一步说明本实用新型的结构和原理。
参照图1,自紧式剪刀由刀剪(1)、刀剪(2)、支承杆(3)、压簧(4)、套管(5)和垫片(6)构成。其中,支承杆(3)、压簧(4)、套管(5)和垫片(6)组成自紧式铰链。其工作原理是:压簧(4)的伸张力分别作用在支承杆(3)的(a)面和套管(5)的(b)面,此时,同支承杆(3)铆连的垫片(6)以及套管(5)的端环(7)受压簧(4)的伸张力的影响,产生同压簧(4)的伸张力方向相反的弹性夹持力,由于这一弹性夹持力的作用,刀剪(1)和刀剪(2)始终紧密相贴。

Claims (1)

1、一种主要由两片刀剪和一副自紧式铰链构成的自紧式剪刀,其特征在于:自紧式铰链由一根支承杆、一根压簧、一个套管和一个垫片构成。
