    • [OBJECT]
      To provide a push button lock which includes a mechanism and its components assembled in a cartridge for setting and storing a security code for locking and unlocking. The cartridge is detachably attached to the inside of a housing so that various designs are available on the surface of the housing. The lock is manufactured and designed in an efficient manner, and requires less maintenance, thereby facilitating mass production. The security code for the lock is easily and readily set or altered with the lock attached to a door and without using a tool. The lock has an increased protection function, thereby improving convenience and safety. Further, a streamlined design of the lock reduces the load applied to a lock pin, prevents damage by tampering and erroneously pushing the push buttons, and thereby enhancing safety in use and increasing productivity.
      [SOLVING MEANS]
      A housing 18 on which a plurality of depressible push buttons are located is provided.
      A lock pin 237 which moves axially with the push button 20 is provided and is engageable with and disengageable from the push button 20.
      A lock plate 155 is provided and formed with a plate key hole 211 and plate lock hole 211a. The lock pin 237 is insertable in the plate key hole 211, and the lock pin 237 abuts the plate lock hole 211a.
      A reset plate 154 is provided, and is parallel to the lock plate 155. A reset spring 205 is provided inside, and axial displacement of a lock pin 237 inserted via the reset spring 205 is maintainable and releasable.
      A driving cam 58 linked to a deadbolt lock 8 is provided, and the deadbolt lock 8 is rotatable and engageable with a movement area of the lock plate 155.
      The push button lock provided here controls a movement of the lock plate 155 via the lock pin 237 when the push button is pressed, and releases an engagement between the lock plate 155 and the driving cam 58.
      A security-code controller 149 which slidably stores the reset plate 145 and the lock plate 155 and are parallel to each other.
      The security-code controller 149 is detachably attached to the housing 18.
    • [对象]提供一种按钮锁,其包括组装在盒中的机构和组件,用于设置和存储用于锁定和解锁的安全代码。 盒可拆卸地附接到壳体的内部,使得在壳体的表面上可获得各种设计。 该锁以有效的方式制造和设计,并且需要较少的维护,从而促进批量生产。 锁的安全代码通过锁附在门上并且不使用工具而容易且容易地设置或改变。 锁具有增强的保护功能,从而提高了便利性和安全性。 此外,锁的流线型设计降低了施加到锁销的负载,防止篡改造成的损坏和错误地推动按钮,从而提高了使用中的安全性并提高了生产率。 [解决方案]设置有多个可按压按钮所在的壳体18。 提供与按钮20轴向移动的锁定销237,并且可与按钮20接合并脱离。锁定板155设置有板键孔211和板锁定孔211a。 锁定销237可插入板键孔211中,并且锁定销237邻接板锁定孔211a。 提供复位板154并且平行于锁定板155.复位弹簧205设置在内部,并且经由复位弹簧205插入的锁定销237的轴向位移是可维护的和可释放的。 设置有与锁死螺栓8连接的驱动凸轮58,并且锁舌8可旋转并与锁板155的移动区域相接合。此处提供的按钮锁通过锁定销控制锁定板155的移动 按压按钮237并释放锁定板155和驱动凸轮58之间的接合。一种安全代码控制器149,其可滑动地存储复位板145和锁定板155并且彼此平行。 安全代码控制器149可拆卸地附接到壳体18。
