下面详细描述本发明的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面结合图1-图3描述根据本发明实施例的静音锁。
根据本发明实施例的静音锁包括锁壳1、斜舌2、第一弹性件21和第二弹性件22，斜舌2与锁壳1可滑动地相连，斜舌2具有位于锁壳1内的第一缩回位置和至少部分凸出于锁壳1外的第一伸出位置。第一弹性件21连接斜舌2和锁壳1并朝第一伸出位置压迫斜舌2，第二弹性件22连接斜舌2和锁壳1并朝第一缩回位置压迫斜舌2，斜舌2位于第一伸出位置时，第一弹性件21的弹性力等于第二弹性件22的弹性力。
根据本发明实施例的静音锁，在关锁或开锁时，斜舌2受到外力按压，并由第一伸出位置向第一缩回位置移动，第一弹性件21和第二弹性件22的弹性力不再平衡。释放外力后，斜舌2在第一弹性件21和第二弹性件22的合力作用下复位，当斜舌2复位至第一伸出位置时，第一弹性件21和第二弹性件22对于移动的斜舌2起到缓冲、减震的作用，辅助斜舌2在第一伸出位置附近往复移动，直至斜舌2的动能耗尽，停在第一伸出位置。
由此，第一弹性件21和第二弹性件22减小了斜舌2在复位时的冲击力度，避免了斜舌2和机械部件(如关锁时的门扣)的机械碰撞和剧烈摩擦，从而降低了开关锁时的噪声，实现了静音的效果。
另外，本实施例中的静音锁不受安装环境的限制，适用范围更广。此外，本实施例中的静音锁免于改造侧条，既保证了侧条的外形美观度，又避免了复杂的加工和装配操作。
可以理解地，斜舌2在第一伸出位置，第一弹性件21作用于斜舌2的力和第二弹性件22作用于斜舌2的力平衡。
在一些实施例中，静音锁还包括第一导向轴23、第一挡板24和活动 板25，第一导向轴23的第一端和斜舌2相连。第一挡板24固设于锁壳1内，第一挡板24设有适于供第一导向轴23滑动穿过的第一过孔，第一弹性件21包括套设于第一导向轴23的第一弹簧211，第一弹簧211压设于斜舌2和第一挡板24之间。活动板25位于第一挡板24背离斜舌2的一侧并与第一导向轴23的第二端相连，第二弹性件22包括套设于第一导向轴23的第二弹簧221，第二弹簧221压设于第一挡板24和活动板25之间。
由此，第一导向轴23和第一过孔的配合实现了对于斜舌2的滑动方向的限制，保证了斜舌2在第一伸出位置和第一缩回位置之间滑动的可靠性。第一弹簧211和第二弹簧221实现了对于斜舌2复位时的减震和缓冲，保证了斜舌2在第一伸出位置和第一缩回位置之间滑动的稳定性，降低了斜舌2的运动噪音。
可以理解地，第一过孔的孔径大体等于第一导向轴23的轴径。
具体地，第一挡板24具有在第一导向轴23的轴向相对的第一端面和第二端面，静音锁还包括第一垫片，第一垫片设于第一挡板24的第一端面，第一弹簧211的第一端止抵于斜舌2，第一弹簧211的第二端通过第一垫片止抵于第一挡板24的第一端面。
具体地，静音锁还包括第二垫片，第二垫片设于第一挡板24的第二端面，第二弹簧221的第一端止抵于活动板25，第二弹簧221的第二端通过第二垫片止抵于第一挡板24的第二端面。
在一些实施例中，静音锁还包括检测舌3、第三弹性件31和拨片32，检测舌3可滑动地配合于锁壳1内，检测舌3具有位于锁壳1内的第二缩回位置和至少部分凸出于锁壳1外的第二伸出位置，检测舌3朝第二缩回位置滑动的方向与斜舌2朝第一缩回位置滑动的方向一致。第三弹性件31连接检测舌3和锁壳1并朝第二伸出位置压迫检测舌3。拨片32位于锁壳1内并与检测舌3相连，斜舌2具有朝向第一挡板24的限位面26，拨片32的至少部分与限位面26抵接。
由此，斜舌2受到外力由第一伸出位置向第一缩回位置移动时，通过限位面26和拨片32的配合，带动检测舌3由第二伸出位置向第二缩回位置移动。斜舌2复位时，检测舌3在第三弹性件31的作用下复位，即重回至第二伸出位置。检测舌3在斜舌2带动下移动，避免了开门时检测舌3 与门框的碰撞，进一步降低了噪声，保证了静音效果。
具体地，第一伸出位置和第二伸出位置在锁壳1的长度方向上对齐，第一缩回位置和第二缩回位置在锁壳1的长度方向上对齐。
在一些实施例中，静音锁还包括第二导向轴33和第二挡板，第二导向轴33的第一端和检测舌3相连。第二挡板固设于锁壳1内，且第二挡板设有供第二导向轴33滑动穿过的第二过孔，第三弹性件31包括套设于第二导向轴33的第三弹簧311，第三弹簧311压设于第二挡板和检测舌3之间。
由此，第二导向轴33实现了对于检测舌3滑动方向的限制，保证了检测舌3滑动的可靠性，第三弹簧311用于向检测舌3提供弹力，辅助检测舌3复位。
可以理解地，第二过孔的孔径大体等于第二导向轴33的轴径。
在一些实施例中，静音锁还包括方舌组件4和第一缓冲件41，方舌组件4和锁壳1可滑动地相连，方舌组件4具有位于锁壳1内的第三缩回位置和至少部分凸出于锁壳1外的第三伸出位置。第一缓冲件41固设于锁壳1内，方舌组件4在第三缩回位置止抵于第一缓冲件41。
由此，第一缓冲件41实现了对于方舌组件4缩回的限位，同时，实现了对于方舌组件4缩回运动的缓冲，避免了方舌组件4的刚性碰撞，进一步加强了降噪静音的效果。
在一些实施例中，方舌组件4包括方舌42和连接架43，方舌42的数量有多个并在锁壳1的长度方向上间隔分布，多个方舌42中的每一者均和锁壳1可滑动地相连，连接架43位于锁壳1内且第一端与多个方舌42的每一者相连，连接架43的第二端在第三缩回位置止抵于第一缓冲件41。
由此，连接架43用于带动多个方舌42的同步移动，多个方舌42的设计进一步加强了静音锁的安全性，第一缓冲件41用于限制连接架43的缩回。
具体地，斜舌2、检测舌3和多个方舌42在锁壳1的长度方向上间隔排布。
为了便于理解，图1中的箭头A所示为锁壳1的长度方向。
在一些实施例中，静音锁包括第二缓冲件44，第二缓冲件44置于锁壳1内并固设在任意相邻两个方舌42之间，方舌组件4位于第三伸出位置 时，第二缓冲件44夹设于锁壳1的周壁和连接架43之间。
由此，第一缓冲件41实现了对于方舌组件4伸出的限位，同时，实现了对于方舌组件4伸出运动的缓冲，避免了方舌组件4的刚性碰撞，进一步加强了降噪静音的效果。
在一些实施例中，第一缓冲件41包括支轴411和柔性套412，支轴411固设于锁壳1内，柔性套412套设于支轴411，连接架43的第二端在第三缩回位置止抵于柔性套412；第二缓冲件44包括柔性块441。
由此，柔性套412实现了对于连接架43缩回的柔性缓冲，柔性块441实现了对于连接架43伸出的柔性缓冲。
具体地，柔性套412的材质可以是橡胶、硅胶或海绵等。
具体地，柔性块441的材质可以是橡胶、硅胶或海绵等。
在一些实施例中，静音锁还包括销轴5和防拆勾6，斜舌2具有安装槽27和第一轴孔28，第一轴孔28在锁壳1的长度方向上延伸并与安装槽27连通，销轴5通过第一轴孔28和安装槽27与斜舌2相连。防拆勾6设有第二轴孔61，防拆勾6通过第二轴孔61套设于销轴5并相对于销轴5可枢转地配合在安装槽27内。
由此，防拆勾6相对于斜舌2可以在安装槽27内进行适量地转动，保证了防拆勾6对于斜舌2的保护效果，提升了斜舌2的安全性，增强了斜舌2的防盗性能。
具体地，安装槽27设于斜舌2的中部。
具体地，第一轴孔28的数量有两个并分设于安装槽27的两侧。
在一些实施例中，第二轴孔61的壁面和销轴5的外周面之间填充有阻尼剂，或者，销轴5的外周面设有阻尼涂层。
由此，阻尼剂/阻尼涂层降低了防拆勾6的回弹速度，进一步加强了降噪静音的效果。
