The specific embodiment
Shown in Fig. 1-5, a kind of centreless escape of the utility model Fire-proof lock, form by lock panel 1, shell 17, dead bolt 2, outer fork 4, interior fork 31, location-plate 3, described lock panel 1 is followed closely pin 7 by being weldingly connected with panel, and described outer fork 4 and interior fork 31 bottoms one side are provided with derivation mechanism.
Described derivation mechanism comprises fixed head 13, fork spring 14, spring support 12, described fork spring 14 1 ends are fixedly mounted on the fixed head 13, the other end is connected with spring support 12, and described spring support 12 1 ends withstand on interior fork 31 and the outer fork 4.
Described dead bolt 2 one sides are provided with changement, described changement comprises dead bolt commutation spring 10, collar 11, slide block 5, described dead bolt commutation spring 10 1 ends withstand on the collar 11, the other end withstands on the slide block 5, described slide block 5 one sides are provided with slide block fixed mount 18, described slide block fixed mount 18 is close to mutually with interior fork 31 and outer fork 4 upper ends one side, and described interior fork 31 and outer fork 4 tops are provided with locking mechanism.
Described locking mechanism comprises location-plate 3, keyhole 22, lining 20, screw 21, latch bolt spring 19, described latch bolt spring 19 1 ends are installed on the shell 17, the other end is connected with slide block fixed mount 18, described screw 21 is installed in a side of location-plate 3 plate faces, described location-plate 3 positions by lining 20, described location-plate 3 one sides are close to mutually with steel ball 9, described steel ball 9 is installed on the steel ball holder 6 by holder spring 8, fork 31 links to each other by adapter sleeve 30 with outer fork 4 in described, and described interior fork 31 and outer fork 4 are installed in the both sides of adapter sleeve 30.
The utility model is to implement like this, as shown in Figure 1, be opening schematic diagram of the present utility model, at this moment, steel ball 9 withstands on the following groove in location-plate 3 left sides, steel ball 9 plays the effect that it is stabilized in this position, at this moment location-plate 3 is in position on the upper side, screw 21 is owing to be installed on the panel of location-plate 3, screw 21 also is in position on the upper side, at this moment, outer fork 4 grip hole 16 in addition clockwise rotates for the center, as shown in Figure 4, the outer fork 4 and the interior fork 31 of adapter sleeve 30 both sides can rotate, when interior fork 31 or outside fork 4 when rotating, drive spring support 12 and be moved to the left, fork spring 14 tightens up, and drives slide block fixed mount 18 simultaneously toward moving right, slide block fixed mount 18 can drive slide block 5 makes dead bolt 2 shrink, door is opened, by rotate outer grip hole 16 can so that door open, after the door unlatching, loosen the active force of outer grip hole 16, because the reaction force of fork spring 14, fork spring 14 stretches, and promotes outer fork 4 and rotates counterclockwise, outer fork 4 withstands on the staple pin 15, and outer fork is classified as.Dead bolt 2 is return under latch bolt spring 19 effects.
As shown in Figure 2, be locking state schematic diagram of the present utility model, this moment, keyhole 22 insertion keys clockwise rotated key, and key turns promotes location-plate 3 and moves down, screw 21 is along with moving down, when screw 21 moved down into certain position, screw 21 had just in time blocked outer fork 4, because screw 21 is installed in a side of location-plate 3, therefore fork 31 in screw 21 moves down and can not influence, as shown in Figure 4.Screw 21 blocks outer fork 4 and clockwise rotates, at this moment can't realize the rotation of outer fork 4 by the active force of outer grip hole 16, but interior fork 31 can move to right by rotating band movable slider fixed mount 18 in the same old way, make dead bolt 2 shrink, this moment, steel ball 9 withstood on an inside grooves above location-plate 3 left sides, can realize the location of location-plate 3 like this, can arbitrarily not rock, when key rotates once more, key is stirred a ledge on location-plate 3 left sides, can allow location-plate 3 up move again, reach state as Fig. 1.
As Fig. 1, Fig. 4, shown in Figure 5, when opening outdoors, key 26 injects in the keyhole 22, outer handle 25 is installed on the outer grip hole 16, Internal handle 24 is installed on the interior fork 31, drive interior fork 31 and 4 rotations of outer fork respectively by Internal handle 24 and outer handle 25, outer plaque 28 is installed in outer side of door, and trim panel 29 is installed in an inboard.
As shown in Figure 1: described changement mainly plays the effect that changes dead bolt 2 directions, because door has outside unlatching or inwardly opens in installation process, therefore dead bolt 2 need change the orientation along with the mode of door installation, by dead bolt 2 is pulled outward, drive collar 11 and be moved to the left this moment, and collar 11 is to make dead bolt commutation spring 10 tighten up, rotating lock tongue 2, dead bolt 2 is rotated 180 degree, and dead bolt 2 can be classified as again then, because the reason of the extension force of dead bolt commutation spring 10.
The effect of latch bolt spring 19 mainly is to withstand on the slide block fixed head 18, when interior fork 31 and outside pull out 4 for forks when all playbacking state, can promote slide block fixed mount 18 toward moving left, guarantee that dead bolt 2 can stretch out.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this manual has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
