Abstract

The utility model relates to a multi-directional door lock with a plug-in core, which is characterized in that the inner of a lock box is provided with a pair of transverse bolts 6, and inclined sliding grooves 6a are arranged on the transverse bolts and are matched with shaft pins 7 arranged on rack bar bolts 8. A pusher dog on a lock core can toggle a link stopper 10 on a gear 9 which drives the rack bar bolts to move horizontally, but the shaft pins drive the transverse bolts to move vertically. The utility model has the advantages of multi-directional locking function and thin lock body, and the utility model can be widely used as a lateral built-in door lock with a plug-in core.

Description

Multi-faceted mortise door lock

The utility model relates to a kind of lockset, particularly a kind of mortise door lock that rolling gate door lock is improved gained.

Existing rolling gate door lock, mainly be to be used for various rolling-gates, its primary structure is gear and the tapered end that a pair of tooth bar bolt, a band hand wheel shaft are set in the lock box, the tooth bar bolt matches with gear, the pusher dog that is provided with on the lock core of tapered end matches with link stopper on the gear, and handwheel is installed on the hand wheel shaft of gear.But there is following shortcoming in it: 1, can only unidirectionally open; 2: can only folk prescription to locking; Need when 3, installing to punch, can't install from the side of door at the door back side.

The purpose of this utility model just provides a kind of novel mortise door lock that can multi-facetedly lock, can install from the side.

To achieve these goals, the utility model has adopted following technical proposals:

On the basis of existing rolling gate door lock (forming) by lock box, tapered end, gear, a pair of tooth bar bolt, a pair of horizontal bolt is set in lock box, each horizontal bolt is provided with oblique chute, and oblique chute matches with pivot pin on the tooth bar bolt.Gear centre is provided with through hole, be provided with rectangular channel in the hole, one handwheel is set in addition, the hand wheel shaft center is a through hole, axle head is provided with a pair of shift fork, and it matches with rectangular channel on the gear, also connects a mounting disc on the hand wheel shaft, the one end cooperates the location with shoulder on the hand wheel shaft, and the other end cooperates with back-up ring and collar location on being associated in hand wheel shaft.Working condition of the present utility model is as follows: 1, turn lock core with key from the front, shifting block on the pusher dog handsetting gear on it, gear is rotated and the telescopic moving of drive tooth bar bolt, move in the oblique chute of the pivot pin on the tooth bar bolt in horizontal bolt and make its generation laterally moving perpendicular to the tooth bar bolt.2, the shift fork on the hand wheel shaft inserts in the rectangular channel in the gear, the switching of (as the user back of entering house) available handwheel control tooth bar bolt under the lock core opening, as required, can be from the hand wheel shaft central through hole with key with its locking or unlatching.

Owing to adopted technique scheme, make to the utlity model has multi-faceted locking function that it is very thin that the thickness of lock body can be done, can be from a reveal face body of packing into, because be provided with through hole in the handwheel, so all available key operated door lock of indoor and outdoor, door lock opened at indoor handwheel.

For the utility model is described in further detail, following routine accompanying drawing provides a most preferred embodiment of the present utility model.

Description of drawings:

Fig. 1 is a main sectional view of the present utility model;

Fig. 2 be the A-A of Fig. 1 to sectional view, and omit lock core, figure middle rack bolt and horizontal bolt are for stretching out state;

Fig. 3 is tooth bar bolt and horizontal bolt retracted mode;

Fig. 4 is the asymmetric installment state of horizontal bolt (tiltedly chute in the same way).

As shown in Figure 1 and Figure 2, lock box 1 inner chamber is symmetrical arranged a pair of tooth bar bolt 8,8a with center line, and each tooth bar bolt is provided with pivot pin 7, and the oblique chute 6a in pivot pin 7 and the horizontal bolt 6 is slidingly matched, and the notch that tooth bar bolt, horizontal bolt are offered from the side of lock box 1 leads to outside the box body.Be provided with a gear 9 at the center of lock box 1, its center is through hole and is provided with a pair of rectangular channel 9a, also is provided with a link stopper 10 on gear 9 end faces.A lock box cover 2 is established in lock box 1 upper end, connects a tapered end 3 on it, the center of its lock core 4 and gear 9 center-aligned, and 4 times client links of lock core, one pusher dog 5, it cooperates handsetting gear 9 to rotate with link stopper 10.Handwheel 11 as shown in Figure 1, the hand wheel shaft center is a through hole 12, axle head is provided with a pair of shift fork 12a, it inserts among the rectangular channel 9a of gear 9 from the hole that open at the back side of lock box 1, also be provided with expanding ring 15, back-up ring 14 and mounting disc 13 on the hand wheel shaft, it is spacing that mounting disc upper end contacts with back-up ring, and the lower end cooperates spacing with shoulder on the hand wheel shaft.Mounting disc is provided with installing hole for being fixed on the doorframe.Fig. 1, state shown in Figure 2 is a locking (tooth bar bolt, horizontal bolt all stretches out) state, key can open and close lock core from positive (tapered end) or the back side (handwheel) both direction, the pusher dog that lock core drives on it when rotating is stirred link stopper 10, making gear 9 rotate (rotating counterclockwise as shown in Figure 2) gears 9 cooperates with tooth on the tooth bar bolt it is reclaimed in box, 7 of pivot pins on the tooth bar bolt move along the oblique chute on the horizontal bolt 6, horizontal bolt is pushed back downwards, till the bossing 6b of horizontal bolt contact lock box side, as shown in Figure 3, be opening this moment, pusher dog 5 is positioned at the right side of link stopper 10, if rotate handwheel 11 (clockwise direction), because being subjected to pusher dog stops (lock core can not rotate), then tooth bar bolt and horizontal bolt all can not stretch out, make pusher dog be positioned at the left side of link stopper if clockwise rotate a circle with key, then rotatable tooth bar bolt and the horizontal bolt of making of handwheel stretches, and this situation is applicable to the switching that has man-hour only to use the handwheel control gate within doors; If it is locked with lock core that the people gos out, then from opening with handwheel within doors.Horizontal bolt shown in Figure 2 is symmetrical installment state, and promptly horizontal bolt is simultaneously to unidirectional motion, if with its asymmetric installation, as shown in Figure 4, then horizontal bolt is simultaneously to different direction motions, in multi-faceted security door.
