Abstract

本实用新型公开了一种双扇门锁,它包括锁芯, 齿轮轴上套有齿轮,齿轮带动齿条转动,其特征是门 外的齿条左、右端头是弹簧,齿条上开有开启槽和锁 固槽与锁芯相应吻合。它具有功能齐全,使用方便, 而且安全系数高,外观美观等特点。

Description

本实用新型涉及一种双扇门锁,是由齿轮带动齿轮条转动的一种新型门锁。
现有的国家专利授权的《一种里外能开的双扇门锁》,专利号为93245275.2,它包括锁芯,锁芯控制齿轮轴,齿轮轴外面是把手,齿轮轴上套有齿轮,齿轮与齿条垂直啮合转动,钥匙插入锁芯里,连动齿轮轴旋转把手,齿轮带动齿条移动,把门锁上。其缺点是:齿轮带动齿条位移距离长,旋转把手时要旋转几圈,这种锁装在大门里,防撬效果差。
本实用新型针对上述缺点,提出一种门锁装在大门外,开门时缩短了齿条的位移距离,齿条上的开启槽和锁固槽与锁芯吻合后即可打开或关闭大门。
本实用新型的任务是这样完成的,它包括锁芯,齿条上连动有齿轮,齿轮套在齿轮轴上,齿轮轴外面是把手,齿轮与齿条垂直啮合转动,其特征在于:锁芯连动齿条,门外的齿条上开有开启槽和锁固槽位移时与锁芯相应吻合,齿条的左、右端头是弹簧。
本实用新型具有以下效果:该锁装在门外,它具有结构简单,轻便坚固,功能全,安全系数高,使用方便之特点,而且锁的外观美观,具有观赏价值。
图1是本实用新型的锁体结构图。
图2是本实用新型锁体安装结构示意图。
结合以上附图详细描述实施例,齿条5上有开启槽2和锁固槽3,锁芯1与它们相应吻合时即是打开大门或关闭大门。齿条5的左、右端头上有弹簧4,齿轮6拨动齿条5垂直运动,控制齿轮6转动的是齿轮轴8,齿轮轴8和装有门外把手7相连,将钥匙插入锁芯旋转90度,锁芯下移和齿条5上的开启槽2脱离,这时齿条5被弹簧4向前弹出一部分,旋转右把手7,齿轮轴8带动齿条向左位移,齿条5上的锁固槽3与锁芯相互对应时,回转钥匙90度,锁芯上移在锁固槽里,即把大门锁上。如门里有人,旋转门里的把手10,即把大门从里关闭,外面的人只要旋转大门外的左把手11即可把大门打开,如需门里的人把门关闭,把销钉9插入销钉孔中,那门外的人无论怎样旋转门外左把手11,也无法打开大门。
