Description

自锁式窗户活动防护栏
技术领域
本发明涉及安装在窗户、阳台上的窗户活动防护栏。
背景技术
窗户活动防护栏安装在窗户、阳台上。目前公知的窗户活动防护栏存在以下缺陷:1、防护栏没有自动关闭的功能,如果使用者打开防护栏后忘记关闭,就有可能造成幼儿坠楼事故;2、安装在防护栏上的门锁没有自动退出钥匙的功能,如果使用者锁上防护栏后忘记取下钥匙,就有可能被幼儿自行打开防护栏造成坠楼事故。
发明内容
本发明的目的是提供一种具有自动关闭功能并且能自动退出钥匙的自锁式窗户活动防护栏。
为此,本发明所述的自锁式窗户活动防护栏,包括与固定框转动连接的防护栏,防护栏上安装有锁体,所述防护栏通过弹簧门铰与固定框转动连接,所述锁体的锁闩为伸缩式,锁闩与锁体之间连接有带动锁闩伸出的弹簧,锁闩的端头带有楔面,在防护栏关闭的过程中,锁闩端头的楔面与固定框上的锁闩阻挡件相碰,使得锁闩自动收缩,在锁体内安装有正对钥匙孔并且与插入钥匙孔内的钥匙顶触的顶触件,顶触件与锁体之间连接有弹簧,在弹簧力作用下顶触件将钥匙顶出锁体。
本发明利用弹簧门铰使防护栏具有自动关闭的功能,而且在钥匙插入锁体后,只要没有人按压钥匙,锁体内的顶触件就会将钥匙顶出,避免钥匙长期插在钥匙孔内。
本发明的优点是可避免因使用者忘记关闭防护栏而造成幼儿坠楼事故,而且钥匙不会遗留在锁体上,可避免幼儿自行打开防护栏造成坠楼事故。
附图说明
图1是本发明实施例的结构示意图;
图2是图1的B-B剖视并且顺时针90度旋转视图;
图3表示从图1的A向看到的钥匙孔形状
图4是图2插入钥匙后的示意图;
图5是图4的钥匙被顶出锁体后的示意图。
具体实施方式
参见图1、图2,自锁式窗户活动防护栏包括与固定框1转动连接的防护栏2(图2省去了防护栏)。固定框1可以是墙体或者一个固定在墙体上的框架。防护栏2可由金属管焊接而成。防护栏2上安装有锁体3。防护栏2通过弹簧门铰4与固定框1转动连接。弹簧门铰4可直接采用市售成品。弹簧门铰4带动防护栏2朝着图1中的逆时针方向转动,使防护栏2打开后能自动关闭。锁体3的锁闩5为伸缩式。锁闩5与锁体3之间连接有推动锁闩伸出的压缩弹簧6。锁闩5的端头带有楔面7。在防护栏2关闭的过程中,锁闩端头的楔面7首先与固定框上的锁闩阻挡件8相碰,通过锁闩阻挡件8对楔面7的作用力使锁闩5自动收缩。在锁闩5上固定有可被钥匙拨动的挡片9。锁体3上的钥匙孔10的形状如图3所示。
参见图1、图2,在锁体3内安装有正对钥匙孔10并且与插入钥匙孔内的钥匙顶触的顶触件11。本实施例所示的顶触件11是一个与锁体3滑动连接的套筒,套筒11与锁体3之间连接有压缩弹簧12。在弹簧力作用下套筒11的端面可将钥匙顶出锁体。
开锁时如图4所示,插入钥匙孔10的钥匙13迫使套筒11后退,当钥匙的凸牙14与锁闩5上的挡片9相对时即可转动钥匙,由钥匙的凸牙14拨动锁闩5上的挡片9,使锁闩5朝着图1中的左边方向滑动,当锁闩5的端头退出固定框上的锁闩阻挡件8后即完成开锁,随后朝着图1中的顺时针方向转动防护栏2即可将防护栏2打开。
开锁后,只要松开拿着钥匙的手,锁闩5就会在压缩弹簧6的弹力下自动伸出锁体3,在锁闩5伸出的同时,锁闩5上的挡片9带动钥匙回转复位,于是如图5所示钥匙13被套筒11顶出锁体。
以上实施例利用钥匙上的凸牙14直接拨动锁闩5,除此之外,本发明也可以像其他常规锁那样,由钥匙通过联动机构带动锁闩5收缩,并且由锁闩5通过联动机构带动钥匙回转复位。
