The specific embodiment:

A preferred embodiment of the present utility model is: referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, this Fire-proof lock includes housing 1, straight hyoplastron 14, tiltedly tongue 22, transmission mechanism and square hole column assembly 6, and square hole column assembly 6 slides mutually for the concentric setting and revolves two of joining and connect upper and lower

square hole post

26,29 outer, interior, handle respectively; Following square hole post 29 is connected by the sliding panel 8 of an interlock plate 27 with transmission mechanism; Upper aperture post 26 cylindricals have the ratchet of the fire prevention safety plate 5 that ratchet 30 and a slice be hinged with square hole post 29 down to link to cooperate, the fire prevention safety plate 5 anti-ignition control system motor driver 4 that is hinged.

The structure of above-mentioned square hole assembly 6 is: packing ring 28 of lower end cylindrical upper sliding sleeve of a following hole post 29 that interior square hole arranged and cooperating with housing 1 wainscot, its middle part suit a slice interlock plate 27, an aperture inserting of a protruding pin 31 and interlock plate 27 is arranged on the following square hole post 29, this protruding pin 31 pass interlock plate 27 also with the pin-and-hole slip inserting of fire prevention safety plate 5, have the normal pin 19 and the sliding panel 8 of transmission mechanism to be connected on the Extendible flake of interlock plate 27; One of the upper end slip socket of following square hole post 29 has the upper aperture post 26 of interior square hole, packing ring 25 of upper end cylindrical upper sliding sleeve of upper aperture post 26 and cooperating with the outer panels of housing 1.

Above-mentioned fire prevention safety plate 5 is bending shape sheet, and the one end is a ratchet, and the other end is and the pin-and-hole of protruding pin 31 insertings that the normal pin of a hinge motor driver 14 is fixed at its middle part.Referring to Fig. 1 and Fig. 2, comprise a sliding panel 8 in the transmission mechanism, there are two to lead poor 2,11 and be slidingly matched with two pilot pins 3,15 that are fixed in housing 1 wainscot respectively on it, there are rectangular slot 17 and oblique strip shaped groove 7 in sliding panel 8 middle parts.Normal pin 19 on the interlock plate 27 of square hole column assembly 6 is in the rectangular slot 17 and is connected, the left profile of rectangular slot 17 is slided with the left surface of the vertical elbow 18 in the rear end of an impact switch 20 and is mated, rectangular slot 17 left profile have convex shoulder to connect coupling with vertical elbow 18 hooks, and the rear end face of impact switch 20 is by 16 supportings of a spring; The rearward end of straight hyoplastron 13 has 7 sliding of a normal pin 9 and oblique strip shaped grooves, and there is convex shoulder 14 at straight hyoplastron 13 middle parts and is supported by spring 12; Tiltedly there is the left surface of normal pin 23 and sliding panel 8 coupling of sliding at tongue 22 middle parts, have on sliding panel 8 left surfaces groove 24 when unlocking condition with oblique 23 sliding joining of normal pin of tongue 22; There is tapered end placement hole 10 at the following right corner place of housing 1.

The Fire-proof lock of this example has automatic blocking when closing the door without key, when meeting fire, can be without key by the function of directly unblanking with outdoor handle outdoors, and its operating principle is as follows:

Under the unlocked conditions of opening the door, go out when locking a door, as long as shut the door, impact switch 17 collides doorframes and inwardly shrinks, and the vertical elbow 18 in its rear end is threaded off with the convex shoulder of rectangular slot 17 left profile, then under the spring force effect of spring 12, straight hyoplastron 13 is protruding, thereafter the normal pin 9 of end is pushed sliding panel 8 to by oblique strip shaped groove 7 and is moved down, then tiltedly vertical 23 of tongue 22 connect with the limit, left side of sliding panel 8 and to melt, thereby make straight hyoplastron 13 and tiltedly tongue lock simultaneously.

When turning the key in the lock usually, to being placed in the tapered end on the tapered end placement hole 10, with key turns tapered end and continuous driving lever thereof, then the bottom of driving lever promotion sliding panel 8 is upwards slided it and is unblanked.

Usually rotate the following square hole post 27 of square hole column assembly 6 with the inner handle in the waiting room for officials, then upwards slide and unblank by interlock sheet 27 drive sliding panels.Rotate the outer outdoor handle of waiting room for officials in the case, inoperative.

When running into fire, the fire prevention safety plate links with upper aperture post 26 under the effect of anti-ignition control system motor driver, makes to pass through square hole column assembly 6 interlock sliding panels 8 by the outer outdoor handle of waiting room for officials, can directly unblank by rotating outdoor handle, enters the room and puts out a fire.
