The second end 142 of the elastic member 140 is coupled to the engaging pin 122 of the locking tongue set 120, so The elastic member 140 is in an elongated state, and an elastic restoring force is generated to pull the fastening plate 130 back toward the locking tongue 121, so that the fastening hook 133 of the fastening flap 130 is further The buckle portion 130 is more difficult to be detached from the accommodating portion 221, and the splicing plate 130 is more difficult to be detached from the splicing seat 2 ,, so that the fire door 099146920 Form No. A0101 Page 8 / Total 26 Page 0992080664-0 201226681 300 It is more stably maintained in the closed position. Referring to FIG. 8 , the lock structure 100 of the fire door lock is unfastened from the stop seat 20G to form an unlocked state. Please refer to the 8th, & and the lake. The adapter lever 170 drives the pivotal connection. The rod (10) moves up along each of the longitudinal grooves 116 and simultaneously interlocks the second linkage 152 of the linkage group 15 to the bottom portion η of the lock seat 110, at this time, due to the first linkage 151 and the The two linking members 152 are connected to each other, so that the first linking member 151 is also pivotally interlocked, thereby causing the first linking member 51 to swing with the positioning pin m as a rotating shaft, since the coupling pin 122 is pivoted The first linking member 151 of the interlocking group 150 and the two linking plates 123 of the locking tongue set 12 are restricted from moving in the first sliding slot 1123 and the second sliding slot 113a, so the coupling pin 122 When the first linking member 151 is driven, the first sliding slot 112a and the second sliding slot 1133 are moved outwardly to simultaneously drive the two linking plates 123, and the locking bolts 121 are driven by the two linking plates 123. The lock tongue 121 is retracted into the lock seat no. At the same time, because the coupling pin 122 moves outward along the first sliding slot 1123 and the second sliding slot 113a, the latching striker 130 is no longer limited by the coupling pin 126, so the elasticity can be The elastic restoring force of the member 14 〇 causes the fastening damper 130 to swing toward the locking tongue 121 with the positioning pin 160 as a rotating shaft, and the locking tongue 121 is received at the limit of the fastening damper 130 In the slot 135, the body 131 of the latching flapper 130 is in contact with the limiting surface 121b of the latching tongue 121. In this embodiment, the limiting surface 121b can be blocked by the latching flapper 130. In order to limit the reset of the bolt 121, when the fire door 300 is opened, when the door is closed again, the stopper 200 pushes the fastening flap 130 to disengage the bolt 121 from the buckle. The limiting slot 135 of the plate 130 is no longer locked. At this time, the locking tongue 121 099146920 form number A0101 page 9 / 26 pages 0992080664-0 201226681 can be reset and protruded from the lock seat 110, and The stopper seat 200 is positioned between the locking tongue 121 and the fastening flap 130 to form a locked state. When the fire door lock combination of the present invention is configured in the locked state, the buckle 1 3 3 of the fastening baffle 1 3 0 can fasten the receiving portion 221 ′ of the crash seat 200 to avoid the fire prevention. When the door 300 or the door frame 4 is thermally deformed in the event of a fire, the fire door lock combination structure can still be maintained in a locked state to prevent the fire door 300 from being opened. The scope of the present invention is defined by the scope of the appended claims, and any changes and modifications made by those skilled in the art without departing from the spirit and scope of the invention are within the scope of the present invention. .
