    摘要： A fire door lock structure includes a stopper disposed at a door frame and a latch assembly disposed at a fire door, wherein the latch assembly comprises a lock base, a latch unit, a blocking member, a pair of male and female means and a linking set. The latch unit includes a latch bolt. The latch unit and the blocking member are swingably disposed at an accommodating slot of the lock base. The blocking member is fastened at the stopper by the pair of male and female means, wherein the male means comprises a fastener formed at the blocking member. In the locked state, the fastener of the male means can be fastened at the stopper to prevent the stopper from being unable to block the latch bolt caused by a deformed fire door or deformed door frame under a fire condition.

    摘要翻译： 防火门锁结构包括设置在门框处的止动件和设置在防火门处的闩锁组件，其中闩锁组件包括锁定基座，闩锁单元，阻挡构件，一对男性和女性构件以及连接 组。 闩锁单元包括闩锁螺栓。 闩锁单元和阻挡构件可摆动地设置在锁定基座的容纳槽处。 阻挡构件通过一对阳和阴构件紧固在止动器处，其中阳装置包括形成在阻挡构件处的紧固件。 在锁定状态下，阳型装置的紧固件可以在止动件处紧固，以防止止动件在火灾状态下不能阻挡由变形的防火门或变形的门框引起的闩锁。

    摘要： A latch structure of fire door lock includes a lock base, a latch unit, a blocking member, an elastic member and a linking set. The lock base comprises an accommodating slot, a first lateral portion having a first sliding slot, and a second lateral portion having a second sliding slot. The latch unit has a combining pin. The blocking member is disposed in the accommodating slot and includes a contacting portion. The contacting portion is pressed by the elastic member. The combining pin is connected at the linking set and the latch unit. Two end portions of the combining pin are slidably disposed at the first sliding slot and the second sliding slot respectively. The end portions of the combining pin are restrained within a first recess of the first sliding slot and a second recess of the second sliding slot respectively.
