As shown in Figure 3, Figure 4, the structure of described lock body is as follows: comprise lock panel 1, drain pan 7 and lid shell 18, one end of latch bolt 2 stretches out from the lockhole at lock panel 1 middle part, the other end of latch bolt 2, can certainly connect by modes such as welding, riveted joints on the tip of the V-arrangement junction plate 3 of lock body inside by screw.One end of latch bolt spring 5 inserts in the medial surface blind hole of latch bolt 2, the other end of latch bolt spring 5 be fixed on drive screw pin 6 on, drive screw pin 6 is fixed on the drain pan 7; The bipod that V-arrangement junction plate 3 diverges to end is two straight flanges, and the outer ledge of described straight flange leans against on the medial surface of drain pan 7, and V-arrangement junction plate 3 can be done in lock body and horizontally slip; Described diverge to the end bipod end respectively with right angle flange 28, the base butt of the medial surface of right angle flange 28 and interior shift fork 19, outer shift fork 17; Interior shift fork 19 is installed side by side with outer shift fork 17, and interior shift fork 19 is semilune, and the one side is with round boss 29, and opposite side is with concave station; Outer shift fork 17 also is semilune, and there is round boss 29 the one side, and opposite side has flange, and described flange sleeve is in described concave station; Be through with the square bar hole on the round boss 29.
Such as Fig. 2, Fig. 5 and shown in Figure 6, the structure of described outer plaque is as follows: comprise the housing 24 and the base plate 25 that are connected on the door-plate, have coaxial through hole on housing 24 and the base plate 25, the two ends of lock core body 11 respectively frame in described two through hole; The periphery at lock core body 11 middle parts is fixedly connected with thumb wheel 10, and thumb wheel 10 can rotate with lock core body 11, and an end of thumb wheel 10 is with dialling button 8, and the other end is with pointed shape projection 30; Device has thumb wheel spring 12 on the base plate 25, and an end of thumb wheel spring 12 and the inwall butt of housing 24, the other end are connected on the side of the pointed shape projection 30 on the thumb wheel 10; Housing 24 interior returning apparatus limited location plates 9, a lateral edges of limiting plate 9 is arranged in the gathering sill 31 of housing 24, and limiting plate 9 can be done in housing and slide up and down; Offer waist-shaped hole 901 on the limiting plate 9, a side of waist-shaped hole 901 also offers groove 902, and groove 902 fastens with dialling button 8, and the upper end of limiting plate 9 is with flange 903; For another example Fig. 2 and shown in Figure 4, outer handle 14 is installed on the housing, and an end of outer handle 14 is connected with square bar 16, and square bar 16 passes in the square bar hole in the boss 29 that inserts behind the described outer plaque on the outer shift fork 17; Also be connected with locking plate 27 on the square bar 16, locking plate 27 is positioned at housing, can rotate with square bar, on the locking plate 27 with the slope, described slope can with the edge butt of the flange 903 of limiting plate 9.
Such as Fig. 2, shown in Figure 4, the structure of described trim panel is as follows: comprise the housing 23 that is connected on the door-plate, be connected with interior handle 20 on the described housing 23, an end of interior handle 20 is connected with square bar 21, square bar 21 pass described trim panel insert in the square bar hole in the boss 29 on the shift fork 19; Square bar 21 on the interior handle 20 is coaxial with the square bar 16 on the outer handle 14, is provided with holly strip 22 between the end face of square bar 14 and square bar 16.
As shown in Figure 4, interior shift fork 19 and described outer shift fork 17 are positioned at the same side of V-arrangement junction plate 3; Holly strip 22 is square, is installed in the inner chambers of flange of outer shift fork 17 opposite sides.
Such as Fig. 2, Fig. 3 and shown in Figure 4, no matter door lock is in is opened or closed condition, handle 20 in rotating, square bar 21 can drive interior shift fork 19 and rotate, the base of interior shift fork 19 promotes the flange 28 of V-arrangement junction plate 3, so that V-arrangement junction plate 3 slides to the right, retract thereby drive latch bolt 2, thereby can under any circumstance drive the soda lock that opens the door.
Such as Fig. 5, shown in Figure 7, rotate counterclockwise key 26, the button 8 of dialling that lock core body 11 drives on the thumb wheel 10 rotates counterclockwise, dial button 8 and drive limiting plate 9 down slidings, the flange 903 of limiting plate 9 upper ends breaks away from locking plate 27, and rotate outer handle 14 this moment, can open door lock.
Such as Fig. 8, shown in Figure 9, clockwise rotate key 26, the button 8 clockwise hour hands of dialling that lock core body 11 drives on the thumb wheel 10 rotate, dial button 8 and drive limiting plate 9 upward slidings, flange 903 and locking plate 27 butts of limiting plate 9 upper ends, rotate outer handle 14 this moment, because locking plate is against on the flange 903 of limiting plate 9, can't rotate outer handle 14.
Installation of the present utility model is very simple: as shown in Figure 1, the drain pan 7 of lock body part is connected by crossed countersunk head screw 15 with lid shell 18; Outer plaque and trim panel are fixed by screws on the door-plate, have marked the installing hole 4 of screw among Fig. 1.
In addition, for existing most of lockset, owing to its locking mechanism is included in the lock body, thereby when mounted, can produce the inconsistent problem of handle opening direction.For example, if door is opened towards a left side, lockset is after installing, and outer handle when then door is opened towards the right side, re-uses same lockset down by opening the door, and lock will be inverted during installation, and outer handle will upwards be carried just and can open door this moment.Use the escape fire-proof lock of structure described in the utility model, owing to its locking mechanism is installed in the outer plaque, thereby just can adjust as required mounting means when mounted, so that no matter a door whichaway is opened, the action direction of inside and outside handle is identical.So also can avoid under emergency, some people do not open because of high-pressure the door situation.
Simultaneously door lock is simple in structure, even also can can't not open because the inner body distortion under hot environment, satisfies in the national standard refractoriness requirement to Fire-proof lock.
More than describing is to explanation of the present utility model, is not to restriction of the present utility model, and the utility model limited range is referring to claim.In the situation of the utility model basic structure, the utility model can be done any type of modification.
