The rear end of the lock tongue is also provided with a dial slot. The dial includes a hinge part and a dialing part at the lower end. The hinge part is articulated on a lock box through a rotating shaft. The rotating shaft is provided with a rotating shaft. The rotating shaft is provided with a rotating shaft. The rotating shaft is provided with a lock box. The rotating shaft is provided with a rotating shaft. The toggle hole can drive the swing of the toggle piece, and the toggle part is provided with a toggle column, and the toggle column is inserted into the dial slot. By adopting the structure of the safety lock tongue in the utility model, the movement of the safety latch tongue can be more precise and the service life is longer. The utility model can be applied to the internal structure of the earth lock.
【技术实现步骤摘要】
一种天地锁的保险锁舌结构
本技术属于门锁
,特别涉及天地锁内的保险锁舌的结构。
技术介绍
现有天地锁一般设置有三种锁舌,即主锁舌,斜锁舌和保险锁舌。保险锁舌采用室内开启和关闭,它具有一定的防盗能力,使用方便安全。在室内无需钥匙就可以上锁,上锁后,屋外即使有钥匙,也无法开门进入屋内。目前天地锁中保险锁舌机构都采用弹簧控制保险锁舌的运动,采用弹簧控制保险锁舌的运动有以下几点不足:1)精度不够高,2)弹簧使用久后容易失效,3)不方便装配。
技术实现思路
本技术提供一种天地锁的保险锁舌结构,其结构中不使用弹簧控制保险锁舌运功,避免了使用弹簧带来的易失效,精度不高等缺点,并此结构简单,方便装配。为实现上述目的,本技术采用如下技术方案:一种天地锁的保险锁舌结构,包括锁盒和衬板,在锁盒和衬板围闭成的腔体内还包括保险锁舌、滑动导柱、拨动片,所述衬板上设有供保险锁舌穿出的锁舌孔,所述滑动导柱与锁盒固定连接,所述保险锁舌中部设有与锁舌孔的中心线相互平行的滑动槽,所述滑动导柱插套在滑动槽内且活动连接,所述保险锁舌的后端部还设有拨动槽,所述拨动片包括上端的铰接部和下端的拨动部,所述铰接部通过转轴铰接在锁盒上,所述转轴设有可带动拨动片摆动的拨动孔,所述拨动部设有拨动柱,所述拨动柱插套在所述拨动槽内。进一步地,所述拨动槽结构为U型槽结构。进一步地,所述拨动片形状为扇形。本技术的有益效果:本技术中采取拨动槽与拨动柱配合来控制保险锁舌的运功,取代了传统保险锁舌中控制其运动的弹簧,这就避免了使用弹簧带了的使用寿命短等一些问题。采用本技术中保险锁舌的结构,可以使得保险锁舌运动更为精准,使用寿命 ...
