Fireproof door lock
The invention relates to a fireproof door lock which comprises an upper lock body and a lower lock body. The lower lock body comprises a lower lock shell and a lower lock rod connected with the lower lock shell in a sliding mode in the vertical direction. The upper lock body comprises an upper lock shell, a clamping plate, a sliding rod connected with the upper lock shell in a sliding mode in the vertical direction, an upper spring bolt rotationally connected with the upper lock shell, a clamping piece connected with the upper spring bolt and a limiting piece located between the clamping piece and the sliding rod. The limiting piece is connected with the sliding rod; the upper spring bolt can drive the clamping piece to rotate to the position below the limiting piece. A clamping groove matched with the clamping plate in a clamping manner is formed in the upper end wall of the upper spring bolt; a middle lock shell is arranged between the sliding rod and the lower lock rod, a sliding rod is arranged on the middle lock shell in a sliding mode in the vertical direction, and connecting rods are connected between the sliding rod and the sliding rod and between the sliding rod and the lower lock rod. The middle lock shell is provided with a driving device used for driving the sliding rod to slide upwards. According to the invention, the unlocked lower lock rod can be separated from the ground, so that the possibility of abrasion of the lower lock rod or the ground is reduced.
本申请涉及一种防火门锁，包括上锁体和下锁体；下锁体包括下锁壳和与下锁壳沿上下方向滑移连接的下锁杆；上锁体包括上锁壳、卡板、与上锁壳沿上下方向滑移连接的滑移杆、与上锁壳转动连接的上锁舌、与上锁舌相连的卡接件、位于卡接件与滑移杆之间位置的限位件；限位件与滑移杆相连；上锁舌可带动卡接件转动至限位件的下方；上锁舌的上端壁设置有用于与卡板卡接配合的卡接槽；滑移杆与下锁杆之间设置有中间锁壳，中间锁壳沿上下方向滑移设置有滑动杆，滑动杆与滑移杆之间、滑动杆与下锁杆之间均连接有连接杆；中间锁壳设置有用于驱动滑动杆向上滑动的驱动装置。本申请可使解锁后的下锁杆与地面保持分离，以减小下锁杆或地面发生磨损的可能性。
