Description

机械自动门锁 技术领域
本发明涉及机械锁领域，具体涉及机械自动门锁。

具体实施方式
如下具体实施方式将结合上述附图进一步说明。
在下文中，阐述了多种特定细节，以便提供对构成所描述实施例基础的概念的透彻理解。然而，对本领域的技术人员来说，很显然所描述的实施例可以在没有这些特定细节中的一些或者全部的情况下来实践。在其他情况下，没有具体描述众所周知的处理步骤。
如图1-9所示，机械自动门锁，包括锁壳1，所述锁壳1内设有斜舌机构2，方舌3，第一传动机构4和第二传动机构5。所述锁壳1的外侧分别设有外推动机构6和锁芯组件7，内侧设有内推动机构8和旋钮9。转动或者推拉所述外推动机构6和所述内推动机构8，外推动机构6和内推机构8能拨动所述第一传动机构4转动，使得所述斜舌机构2的端部从门框内退出。所述旋钮9和所述锁 芯组件7均能拨动所述第二传动机构5转动，使得所述方舌3的端部卡入门框内或从门框内退出。所述第一传动机构4包括内传动组件40和外传动组件41，以及离合组件42。所述外推动机构6拨动所述外传动组件41转动，所述内推动机构8驱动所述内传动组件40旋转。所述第一传动机构4与所述第二传动机构5之间设有第三传动机构10，所述第二传动机5构与所述斜舌机构2之间设有第四传动机构11。所述第二传动机构5拨动所述第三传动机构10推动所述离合组件42与所述内传动组件40和外传动组件41离合；在离合组件42与内传动组件40和外传动组件41啮合时，外推动机构6带动外传动组件41转动，外传动逐渐41带斜舌机构2滑动。所述斜舌机构2从门框退出时，斜舌机构2拨动所述第四传动机构11，所述第四传动机构11再拨动所述方舌3从门框内退出。因此，方舌3锁入到门框内时，第四传动机构11对斜舌机构2起到限位作用，并且同时带动第三传动机构10往下运动，使得离合组件42与内传动机构40处于分离状态，因此在房门外时，能转动外推动机构6或者转动外推动机构6，从而不会造成外推动机构6受到硬力而受损，达到对门锁起到保护作用。在房门的内侧时，内推动机构8能带动内传动组件40，从而达到斜舌机构2与门框分离；并且在方舌3锁入到门框内时，第四传动机11构限位斜舌机构2；当在室内打开斜舌机构2时，斜舌机构2同时会拨动第四传动机构11，由于第四传动机构11带动第二传动机构5，从而达到将方舌3与门框分离，因此，在房门内 侧时，无论是何种锁紧方式，均可只操作内推动机构就能实现将门打开，从而给居民开门造成便利。
如图1和图4所示，所述内传动组件40包括与内推动机构8连接的第一连接杆400和套于所述第一连接杆400上的拨动凸轮401。所述内推动机构8推动所述第一连接杆400和所述拨动凸轮401转动，所述拨动凸轮401推动所述斜舌机构2。第一连接杆400为方轴或者其他的多变形轴，拨动凸轮401套在第一连接杆400上的孔位方孔或者多变形孔。
所述外传动组件41包括与所述外推动机构6连接的第二连接杆410，套于第二连接杆410上的连接拨块411。第二连接杆410为方轴或者其他的多变形轴，连接拨块411套在第二连接杆410上的孔位方孔或者多变形孔。所述连接拨块411的端部设有滑槽，所述拨动凸轮401的端部设有卡槽。所述离合组件42包括一端与所述锁壳1枢接连接的摆臂420和滑动连接在所述摆臂420上的滑动啮合块421；所述滑动啮合块421与所述滑槽滑动连接。在旋钮9或者锁芯组件7拨动第二传动机构5旋转时，所述第三传动机构10推动所述摆臂420摆动，所述滑动啮合块421沿所述滑槽滑动卡入所述拨动凸轮401的卡槽内。实现拨动凸轮401与连接拨块411连接，所以转动第二连接杆410时，达到带动拨动凸轮401转动。所述第三传动机构10往下运动复位时，一弹性复位件422推动所述摆臂420复位。弹性复位件422为设于锁壳1内壁与摆臂420之间的压缩弹簧，并压缩弹簧是推动摆臂420绕枢轴往远离拨动凸轮401端摆动。弹性复 位件422还可是设于摆臂420与锁壳1之间的扭转弹簧；扭转弹簧。在连接拨块411的外侧对称地设置有两个限位凸块，在锁壳1上设置有与避空限位凸块的避空槽。
进一步，所述拨动凸轮401靠近所述内推动机构8的一侧还设有与所述锁壳1转动连接的辅助连接拨块43，所述辅助连接拨块43上设有第二滑槽，所述啮合块421的一侧与所述第二滑槽滑动连接；所述连接拨块411与所述锁壳1转动连接。在连接拨块411的外侧对称地设置有两个限位凸块，在锁壳1上设置有与避空限位凸块的避空槽。辅助连接拨块43的外侧对称地设置有两个第二限位凸块，在锁壳1上设置有与第二避空限位凸块的第二避空槽。因此通过辅助连接拨块43对啮合块421起到支撑和限位作用，保证啮合块421与卡槽卡合的稳定性。辅助连接拨块43与连接拨块411通过一销钉连接，并且在拨动凸轮401上设有避空销钉的弧形槽；通过销钉对辅助连接拨块43和连接拨块411起到定位和增加强度作用。
进一步，所述摆臂420与所述啮合块421连接端为弧形。所述啮合块421的两端分别设有避空所述拨动凸轮401的第一避空槽，和避空所述摆臂420的第二避空槽。所述第一避空槽使得所述啮合块421形成两分别与所述第一滑槽和所述第二滑槽连接的凸起，所述第二避空槽的两内侧壁设有限位在所述摆臂420上的限位凸块。在啮合块421与卡槽卡合时，第一避空槽与第二避空槽中间形成的实体卡入到卡槽内。并且摆臂420与啮合块421连接端为弧形；因此在 啮合块421与卡槽卡合后，在第一连接杆400和第二连接410转动时，啮合块421能随摆臂420转动。
如图1、5和6所示，所述斜舌机构2包括贯穿所述锁壳1一侧的斜舌组件20和连接在所述斜舌组件20与拨动凸轮401之间的连接件21；在锁壳1上设有多个平行的导向槽，连接件21上设有伸入到导向槽内的滑块。所述拨动凸轮401转动拉动所述连接件21和所述斜舌组件20直线滑动；所述锁壳1的内侧设有限位板100，所述限位板100上设有推动所述斜舌组件20复位的复位弹簧22；所述连接件21的底侧设有推动滑槽或拨动凸台，所述第四传动机构11的端部伸入所述推动滑槽内或者第四传动机构11的上端位于所述拨动凸台的一侧。通过第一连接杆400或者第二连接杆410带动拨动凸轮401转动，拨动凸轮401拉动连接件21克服复位弹簧22的弹力，使得斜舌组件20收缩到锁壳1内。
如图6所示，所述斜舌组件20包括与所述连接件21连接的拉杆200和与所述拉杆200枢接连接的斜舌201。所述拉杆200上设有导向滑槽202，所述斜舌201与所述拉杆200枢接的枢轴贯穿所述导向滑槽202；所述拉杆200上设有限位台阶203，所述斜舌201上设有与所述限位台阶203配合的限位缺口204；所述连接件21拉动所述拉杆200往所述锁壳1内侧运动，所述斜舌201的侧面受力时，所述枢轴在所述导向滑槽202内滑动，使得所述限位台阶203与所述限位缺口204脱离，在轻推门时，斜舌201的侧面受力，使得所述斜舌201往 所述锁壳1内侧转动。因此轻推内推动机构8或者轻微转动内推动机构8，从而可将门打开。
进一步，所述连接件21的两侧均设有连接孔，所述拨动凸轮401的两侧均有分别延伸到两所述连接孔内的拨动连接位。拨动连接位的外侧面为弧形面；因此在拨动凸轮401转动时，拨动连接位拉动连接件21滑动。
如图7-8所示，所述第二传动机构5包括与所述锁芯组件7中的拨轮固定连接的旋转件50，设于旋转件50外圈的齿形51，转动连接在所述锁壳1上的拨动齿轮52，设有所述拨动齿轮52上拨动所述方舌3运动的拨块53，以及定位所述拨动齿轮52的扭转弹簧54；所述拨动齿轮52与所述旋转件50外圈的齿形51啮合；所述旋钮9与所述锁芯组件7中的拨轮连接。因此通过对应的钥匙插入到锁芯组件7的锁芯内，转动拨轮，或者通过旋钮9带动拨轮旋转，拨轮带动旋转件50旋转，由旋转件50摆动拨动齿轮52旋转，从而使得拨块53拨动方舌3滑动。
进一步，所述方舌3包括贯穿所述锁壳1侧面的卡入部30，限位在所述锁壳1内侧的限位部31，以及与所述拨块53连接的连接部32。所述连接部32上设有拨动槽33，所述拨块53的端部设于所述拨动槽33内。所述拨动槽33的两侧设有定位所述拨块53的定位槽34。拨块53的端面与侧面的夹角为90°，定位槽34为V形槽；在拨块53拨动方舌3滑动时，拨块53的端部卡瑞到定位槽34内，从而能对拨块53起到止推作用。
如图1、4、7和8所示，所述第三传动机构10包括与所述锁壳1滑动连接的推块1000和所述拨动齿轮52枢接连接的第一连接臂1001；所述推块1000的内侧面与所述摆臂420的外侧面贴合；钥匙或者所述旋钮9拨动所述锁芯组件7中的拨轮旋转，所述拨轮带动所述拨动齿轮52转动，所述第一连接臂1001推动所述推块1000滑动，使得所述摆臂420推动所述啮合块421卡入所述拨动凸轮401内的所述卡槽内或者从所述卡槽内滑出；从而实现离合。推块1000的内圆弧面与摆臂420的外圆弧面贴合。
所述连接件21靠近所述第四传动机构11的一侧设有限位。所述第四传动机构11包括与所述锁壳1枢接连接的推动摆臂110，一端枢接在所述推动摆臂110远离所述连接件21的一端，另一端与所述拨动齿轮52枢接的第二连接臂111；所述推动摆臂110的端部伸入所述限位槽内。
如图2-3和图9所示，所述内推动机构8包括与所述锁壳1固定连接或与门固定连接的第一安装板80和第一安装座81，与所述第一安装板80转动连接的第一旋转连接组件82，所述第一旋转连接组件82的一端与所述内传动组件40中第一连接杆400连接，另一端伸入所述第一安装座81内。所述第一安装座81上枢接有一与所述第一旋转连接组件82卡接的第一旋转摆臂83；所述第一旋转摆臂83的一端穿过所述第一安装座81延伸到外侧。推动或拉动一转动连接在所述第一安装座80上或者固定连接在所述第一旋转摆臂83外端的内推拉 手柄84，使得所述第一旋转摆83臂绕枢轴旋转拨动所述第一旋转连接组件82旋转。
所述外推动机构6包括与所述锁壳1固定连接或与门固定连接的第二安装板60和第二安装座61，与所述第二安装板60转动连接的第二旋转连接组件62，所述第二旋转连接组件62的一端与所述外传动组件41中的第二连接杆410连接，另一端伸入所述第二安装座60内；所述第二安装座60上枢接有一与所述第二旋转连接组件62卡接的第二旋转摆臂63；所述第二旋转摆臂63的一端穿过所述第二安装座60延伸到外侧；推动或拉动一转动连接在所述第二安装座61上或者固定连接在所述第二旋转摆臂63外端的内推拉手柄64，使得所述第二旋转摆臂63绕枢轴旋转拨动所述第二旋转连接组件62旋转。因此只需推或拉内推拉手柄64和内推拉手柄64方可将门打开，从而代替传统的转动式把手，达到便于门打开。
如图9所示，所述第一旋转连接组件82包括贯穿所述第一安装板80的第一旋转套820和套于所述第一旋转套820内端的第一扭力弹簧821；所述第一旋转套820外端的一侧设于与所述第一旋转摆臂83卡接的第一凸块822。第一扭力弹簧821的两端限位在第一安装板80内侧的限位凸台上，中间固定连接在第一旋转套820的端部。因此第一旋转套820旋转后，通过第一扭力弹簧821复位，达到带动内推拉手柄684复位。
所述第二旋转连接组件62包括贯穿所述第二安装板60的第二旋转套620和套于所述第二旋转套620内端的第二扭力弹簧621；所述第二旋转套620外端的一侧设于与所述第二旋转摆臂63卡接的第二凸块622。因此第二旋转套620旋转后，通过第二扭力弹簧621复位，达到带动外推拉手柄64复位。
