Abstract

A night lock without a lock cylinder comprises a lock shell (2), a ball (9) and a ball spring (10), and is characterized in that the lock shell (2) is internally provided with a hand shaft (3), an outer cone ring (4) and an inner cone ring (5); the upper end surface of the lock shell (2) is provided with a big handle (1), an arc small handle groove (13) and a keyhole (12); a key (14) is not provided with a handle, and the tail part of the key is provided with a snap ring hole (15); the outer end of the hand shaft (3) passes through a through hole at the upper end surface of the lock shell (2) and is connected into a whole with the big handle (1), and the other end thereof is connected with a bolt; the inner cone ring (5) is fixedly connected with the middle-rear part of the hand shaft (3); and the outer cone ring (4) is rotatably contacted with the inner wall of the lock shell (2). The night lock has novel structure, reasonable design, has the functions of preventing the technical lock drawing and the unlocking by violence, and greatly improves the safety and the prevention of burglary of the night lock.

Description

No lock core marble lock

Technical field

The utility model relates to mechanical lockset, particularly a kind of no lock core marble lock.

Background technology

All locksets mostly are the cylinder lock type at present.The basic principle of cylinder lock is: in the middle of the tapered end lock core is arranged, lock core directly or indirectly connects with dead bolt, drives the dead bolt motion when lock core rotates, thereby realizes unblanking.If lock core is blocked by the pellet shot from a slingshot in the tapered end, lock core can not rotate generally speaking.Keyhole is arranged on the lock core, and supporting key enters Kong Zhonghou, touches corresponding pellet shot from a slingshot, and lock core no longer is stuck, and can rotate, and at this moment rotational lock core can drive dead bolt and unblanks.

But existing cylinder lock has two tangible safety defects, and one is easily drawn out by technology, and the man of skill can stretch into keyhole with iron wire or other instrument and touch pellet shot from a slingshot without key, thereby realizes no key unlocking; Its two, easily opened by violence because lock core is weak parts, easily unblanked by electric drill or other instrument strong destruction.

Summary of the invention

The purpose of this utility model provides a kind of no lock core marble lock with high safety performance and theftproof performance.

Described no lock core marble lock, comprise lock housing, pellet shot from a slingshot, marble spring, it is characterized in that: be provided with handle axle, outer conical ring, interior conical ring in the described lock housing, be provided with big handle, the little handle slot of arc, keyhole in the lock housing upper surface, described key does not have handle, and its afterbody is provided with the clasp hole; Described handle axle outer end is passed lock housing upper surface through hole and is connected as a single entity with big handle, and the other end can connect with dead bolt, and described interior conical ring and handle axle postmedian connect firmly, and described outer conical ring can rotate with lock-shell lining and contact.Many group marble springs, pellet shot from a slingshot are installed in the pellet shot from a slingshot hole in described on the conical ring.The upper surface of described outer conical ring is fixedly connected with little handle, and little handle can be in little handle slot and its sliding-contact.The upper surface of described outer conical ring is provided with key.The conical surface of outer conical ring and interior conical ring can mate chimeric.

The utility model has been cancelled traditional lock core at weakness of the prior art, adopts handle axle to replace, and rotates this handle axle, can drive dead bolt and unblank.Its feature is: 1, block handle axle with pellet shot from a slingshot at ordinary times it can not be rotated, like this dead bolt is pinned, because the intensity of handle axle is higher, can uprising preferably power unblank; 2, since keyhole away from the pellet shot from a slingshot position, key enters Kong Zhonghou, still touch less than pellet shot from a slingshot, and, between key and the pellet shot from a slingshot spacer is arranged, even from keyhole, put in iron wire or other instrument all can not contact pellet shot from a slingshot, accomplished anti-drawing fully; 3, key does not have handle, the taking-up that inserts in the hole of available clasp.

The utility model novel structure, reasonable in design, have anti-technology and draw lock and anti-violence unlocking function, greatly improved the safety and the theftproof of cylinder lock.

Description of drawings

Fig. 1 is the utility model vertical view,

Fig. 2 is the tapered end front view after the wisp hand puts the key motion in place,

Fig. 3 is the A-A sectional drawing of Fig. 2,

Fig. 4 is that big handle draws outward and makes key to bitmap,

Fig. 5 is no handle key figure.

Among the figure: conical ring, 6-lock housing bonnet, the little handle of 7-, 8-key, 9-pellet shot from a slingshot, 10, marble spring, 11-dead bolt, 12-keyhole, the little handle slot of 13-, the 14-key flank of tooth, 15-clasp hole in the big handle of 1-, 2-lock housing, 3-handle axle, the outer conical ring of 4-, the 5-.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified: among Fig. 1,2,3, described no lock core marble lock, comprise lock housing 2, pellet shot from a slingshot 9, marble spring 10, it is characterized in that: be provided with handle axle 3, outer conical ring 4, interior conical ring 5 in the described lock housing 2, be provided with big handle 1, the little handle slot 13 of arc, keyhole 12 in lock housing 2 upper surfaces, described key 14 no handles, its afterbody is provided with clasp hole 15; Described handle axle 3 outer ends are passed lock housing 2 upper surface through holes and are connected as a single entity with big handle 1, and the other end can connect with dead bolt, and described interior conical ring 5 connects firmly with handle axle 3 postmedians, and described outer conical ring 4 can rotate with lock housing 2 inwalls and contact.Many group marble springs 10, pellet shot from a slingshot 9 are installed in the pellet shot from a slingshot hole on the interior conical ring 5.The upper surface of described outer conical ring 4 is fixedly connected with wisp hand 7, and wisp hand 7 can be in little handle slot 13 and its sliding-contact.The upper surface of outer conical ring 4 is provided with key described in Fig. 4.Outer conical ring 4 can mate chimeric with the conical surface of interior conical ring 5.

Its course of work is: will not have handle key 15 and insert tapered end from keyhole 12, and with the outer conical ring of wisp hand 13 drives 4 mechanisms this key is moved in the tapered end enclosed inside.After the key motion puts in place, big handle 1 is pulled outwardly, makes outer conical ring 4 chimeric, make the pellet shot from a slingshot 9 on the key shake-up handle axle with the conical surface coupling of interior conical ring 5.Like this, big handle 1 just can rotate, and as rotating big handle 1 again and driving dead bolt, realizes unblanking.
