Abstract

本实用新型公开了一种安全门锁,其由锁体(1)、旋钮(2)、锁销(3)及与锁销(3)对应的销孔盒(4)组成,锁销(3)的外侧面为直面。本实用新型锁门时,需借助钥匙,克服了钥匙丢入屋内的不足,且具有较强的防盗性能。

Description

安全门锁
本实用新型涉及一种锁,特别是涉及一种带锁销的门锁。
目前市场上销售及用户使用的门锁是由锁体、旋扭、锁销及与锁销对应的销孔盒组成,锁销有锥角,其外侧面是有一定弧度的斜面。锁门时,只需轻轻一碰,锁销便会通过斜面的外压力缩回,再弹入销孔中完成锁门。但是其存在着以下之不足:门锁在无需钥匙的情况下,会轻易地锁上,这很容易造成因疏忽忘记带钥匙,使钥匙丢入屋内而无法再进入的弊病;此外,这样的门锁防盗性能差,从门缝中插入硬片便很容易将锁销缩回,破门而入,从而增大了用户的不安全感。
本实用新型之目的在于提供一种改进的门锁,其克服了现有技术上述之不足,具有防盗性能好及使用寿命长等优点。
为达到上述之目的,本实用新型采取以下的技术方案:本实用新型由锁体、旋扭、锁销及与锁销对应的销孔盒组成,其特征在于:锁销的外侧面为直面。
本实用新型采取上述之结构,具有以下的有益效果:由于本实用新型的锁销采用了直面体,锁门时需借助钥匙方可使锁销缩入并弹入销孔盒中,克服了钥匙丢入屋内的不足,同理,从门缝中插入硬片也无法将锁销缩入,增强了其防盗性能。另外,这种借助钥匙锁门的方法,还避免了对门及锁销的撞击,在一定程度上会提高门锁及门的使用寿命。
下面结合附图对本实用新型做进一步详细介绍:
图1为本实用新型结构简图。
在图1中,本实用新型由锁体1、旋扭2、锁销3及与锁销3对应的销孔盒4组成,锁销3由旋扭2控制伸缩,锁销3的外侧面为直面,其可为圆柱体或其它多棱柱状体。
