Abstract

本发明公开了一种带自动卡舌的锁，其结构包括锁体、锁舌、锁芯、拨杆、卡舌和回位弹簧；所述锁舌的上侧上设有凹槽；所述锁舌的后段的上侧设有挡块；所述锁舌的上方设有卡舌；所述卡舌呈7字形的块状结构；所述卡舌的前端与所述锁舌上的凹槽适配。本发明的有益效果是：因为卡舌的前端位于所述锁舌的凹槽中并将锁舌卡住导致如果不用钥匙开锁则无法用卡片从门缝中将锁舌拨开，所以本发明在关上门后无需将门反锁就能防止他人利用卡片将门打开。

Description

带自动卡舌的锁
技术领域
本发明涉及一种锁，尤其涉及一种带自动卡舌的锁。
背景技术
传统的锁在关上门后可以用卡片等片状物块将楔形结构的锁舌离开门框从而将门打开。
发明内容
本发明所要解决的问题在于提供一种带自动卡舌的锁，其结构包括设计新颖，使用方便，在关上门后无需将门反锁就能防止他人利用卡片将门打开。
为了解决以上问题，本发明的技术方案如下：
一种带自动卡舌的锁，其结构包括锁体、锁舌、锁芯、拨杆、卡舌和回位弹簧；所述锁舌的上侧上设有凹槽；所述锁舌的后段的上侧设有挡块；所述锁舌的上方设有卡舌；所述卡舌呈7字形的块状结构；所述卡舌的前端与所述锁舌上的凹槽适配；所述卡舌能绕固定轴转动；所述卡舌向上转动时其前端能从所述凹槽中离开；所述锁舌的尾部设有回位弹簧；所述锁舌的下方设有锁芯；所述锁芯的外围设有拨杆；所述拨杆的上端位于所述卡舌的下侧方；所述拨杆能绕所述锁芯转动；所述拨杆的转动能将卡舌进行逆时针转动使得卡舌的前端从所述凹槽中离开；所述拨杆的上端的外侧设有横向凸出的凸块；所述拨杆逆时针转动时所述凸块能顶住所述锁舌上的所述挡块向后移动；所述卡舌的前端位于所述锁舌的凹槽中时所述锁舌便无法左右移动。
本发明的有益效果是：因为卡舌的前端位于所述锁舌的凹槽中并将锁舌卡住导致如果不用钥匙开锁则无法用卡片从门缝中将锁舌拨开，所以本发明在关上门后无需将门反锁就能防止他人利用卡片将门打开。
附图说明
图1为本发明实施例中卡舌的前端位于锁舌的凹槽中时的结构示意图。
图2为本发明实施例中转动拨杆使得卡舌的前端离开锁舌上的凹槽时的结构示意图。
图3为本发明实施例中转动拨杆使得卡舌的前端离开锁舌的凹槽后拨杆上的凸块进一步将锁舌向后推动后时结构示意图。
具体实施方式
下面结合附图和实施例对本发明作进一步说明：
如图1所示，本发明其结构包括锁体1、锁舌2、锁芯3、拨杆4、卡舌5和回位弹簧7；锁舌2的上侧上设有凹槽20；锁舌2的后段的上侧设有挡块21；锁舌2的上方设有卡舌5；卡舌5呈7字形的块状结构；卡舌5的前端与锁舌2上的凹槽20适配；卡舌5能绕固定轴转动；卡舌5向上转动时其前端能从凹槽20中离开；锁舌2的尾部设有回位弹簧7；锁舌2的下方设有锁芯3；锁芯3的外围设有拨杆4；拨杆4的上端位于卡舌5的下侧方；拨杆4能绕锁芯3转动；拨杆4的转动能将卡舌5进行逆时针转动使得卡舌5的前端从凹槽20中离开；拨杆4的上端的外侧设有横向凸出的凸块；拨杆4逆时针转动时凸块能顶住锁舌2上的挡块21向后移动；卡舌5的前端位于锁舌2的凹槽20中时锁舌2便无法左右移动。
本发明是这样使用的：如图1、图2和图3所示，当锁舌2的前端伸出锁体1将门锁上时卡舌5的前端位于锁舌2上的凹槽20中使得锁舌2无法缩回到锁体1中，此时用卡片从门缝中是无法将锁舌2拨动打开门的。如果要打开门，则将钥匙插入到锁芯3中逆时针转动锁芯时，套在锁芯3上的拨杆4逆时针转动，拨杆4首先将卡舌5向上顶使得卡舌5的前端脱离开锁舌2上的凹槽20，然后拨杆5的继续转动使得拨杆5上端的凸块顶住锁舌2后段的挡块21并将锁舌2向右推动使得锁舌2的前端完全缩回到锁体1中从而完成了开锁。
