Abstract

一种门锁防盗装置,由加厚钢板(1),连接器(2), 锁定器(4)和锁头(5)构成。其特征在于:连接器(2) 和锁定器(4)是两套筒,由螺纹连接,在连接器(2)通 孔内带有一防钻器(3),防钻器(3)两端贴住加厚钢板 (1)和锁头(5),防钻器(3)为一圆片,中间开有通槽 (6)。

Description

本实用新型属于一种门锁保护装置,特别是一种防电钻破坏的门锁保护装置。
目前,普通安全防盗门、保险柜、铁皮柜的门锁,其锁芯均暴露在外面,用电钻从外部直接可以强行开启,防盗能力差。
本实用新型的目的在于解决上述现有技术存在的问题,提供一种可防电钻破坏的防盗装置。
本实用新型的目的是用如下方式完成的:
门锁防盗装置由加厚钢板1、连接器2和锁定器4是两套筒,由螺纹连接,在连接器2通孔内带有一防钻器3,防钻器3两端贴住加厚钢板1和锁头5,防钻器3为一圆片,中间开有通槽6。
本实用新型与现有技术相比具有如下优点:
安装、使用简便,受电钻破坏时,防钻器能随钻头高速旋转,使钻头无法达到锁芯,从而保护门锁,本实用新型可用普通门锁改进,结构简单。
下面结合附图对本实用新型作进一步描述:
图1是本实用新型的剖视图
图2是本实用新型除去门框和钢板的外形图
在图1中:1,加厚钢板;2,连接器;3,防钻器;4,锁定器;5,锁头。
图2中:6,通槽。
在图1中,锁头5为普通锁头(未剖视),钢板带有圆孔,防钻器3与连接器2的内孔为间隙配合。
