Abstract

The utility model relates to a double-core theft proof alarm lock, which has an outer lock core and an inner lock core installed in the tapered end. A marble is hidden between the inner lock core and the tapered end, and the space between the back end of the inner lock core and a back cover is also provided with a marble. A driving bar connected with a bolt is provided with gears and engages with the gear portion of the back end of outer lock core. A key comprises a key body, a key gear and sems. The utility model can enhance the burglarproof function effectively because the message of the marbles and the key doesn't expose. Simultaneously, because the construction can be disassembled, even if the key is lost but the key message isn't remembered, the key can be self-matched to open the lock, thereby making the users convenient. A line-fixed lock, the key gears and screws can be disassembled at any time, in order to prevent the key message being exposed. The alarm contact point of the utility model can put out the unlocking message, thereby intelligentizing the mechanism lock.

Description

Twin-core burglar alarm lockset

Affiliated technical field

The utility model relates to a kind of lockset, especially effectively the lock ﹠ key of burglar alarm.

Background technology

At present, known cylinder lock has only a lock core, and pellet shot from a slingshot is visible, and therefore, lock and key are revealed easily the information of unblanking, and key loss be difficult to enter, bring inconvenience for work and life.

Summary of the invention

Expose in order to overcome existing lockset pellet shot from a slingshot and key bit information, drawbacks such as key loss is difficult to unblank, the utility model provides a kind of twin-core burglar alarm lockset, the not only relevant pellet shot from a slingshot information of this lockset does not expose, and can be under the situation of key loss, assemble a key unlocking easily, therefore, totally unnecessary worried for losing key.

The technical solution of the utility model is: a kind of twin-core burglar alarm lockset, comprise lock body, tapered end, trace and dead bolt, lock core, key etc., it is characterized in that: in the circular tapered end that links to each other with lock body circular outer lock core is housed, be equipped with section in the outer lock core for falling the circular internal cylinder of " mountain " font, have on the bottom of internal cylinder and the bonnet same position and be cross pellet shot from a slingshot hole, and spring and pellet shot from a slingshot be housed, the top of tapered end and outer lock core is 90 degree at interval, radially have number row pellet shot from a slingshot hole, the internal cylinder correspondence position has chute, spring and pellet shot from a slingshot are housed in the pellet shot from a slingshot hole, in outer lock core bottom outer rim and bonnet junction trace is housed, and loads onto trace on the position of outer lock core trace driving gear, bonnet links to each other with the tapered end screw, interior, the outer lock core correspondence position is equipped with alarm actuating contact, and draws lead and link to each other with alarm; Its trace is two, and one is connected with circular dead bolt for straight-bar, and the centre has one section to be the tooth bar shape, another is the door word shape, and the Men Dingyi end is connected with the flat dead bolt, under the dead bolt spring is housed, door word connecting rod has a tooth on one side, handle is equipped with in the another side bottom; Its outer lock core bottom does that a tooth is arranged, and tooth top and cylindrical are contour, and before this tooth, several teeth are made to have in the position, certain angle of staggering; Key is by key body, and key bit and Screw assemble, and key body is that hollow metal pipe and 4 are the cross metal wing and handgrip is formed, metal wing equal intervals has skewed slot, metal wing top has screw hole, and key bit is contained in the skewed slot, and screw is contained in the screw hole.

The beneficial effects of the utility model are, do not leak the information of unblanking of tapered end and key, further strengthen anti-theft feature, just can utilize key standard component assembly key unlocking, removed because of losing the worry that key is kept outside of the door as long as remembered the information of own key simultaneously.

The specific embodiment

Require to make component according to the utility model technical scheme, assemble then, internal cylinder 1 is packed among the outer lock core 2, chute 9 is aimed at pellet shot from a slingshot hole 25, refill circular tapered end, also make simultaneously the alignment of pellet shot from a slingshot hole, pack into one by one then pellet shot from a slingshot and spring are again with the metal shutoff of the hole on the tapered end outer rim, in the lock body 5 of being packed in the tapered end bottom then, again dead bolt 6 and trace 10 are assembled, tooth position on the trace is corresponding with the tooth position on the outer lock core equipped, and the dead bolt adjustment stretched out the preformed hole of lock body 5, in the shell hole of bonnet 21, load onto spring and pellet shot from a slingshot, and with the corresponding assembling in position, pellet shot from a slingshot hole of internal cylinder, again bonnet and tapered end are screwed.After the key standard component is made, key teeth groove on the metal wing of key body 12 inserts certain key bit 16 for 13 li then, screw hole on the top is loaded onto screw 15 for 14 li, and the pellet shot from a slingshot in its lock core is to select assembling for use according to the assembling situation of key bit and screw.The utility model can also be drawn lead device taking alarm from alarm actuating

contact

7,8.

When unblanking, anchor point inserts key in the lock core by the key conduit along unblanking, the pellet shot from a slingshot at internal cylinder rear portion enters screw on the key, correct key can rotate internal cylinder, when internal cylinder is rotated, be hidden under the effect of pellet shot from a slingshot on the internal cylinder and enter in the key conduit at spring, join the correct key of tooth and just can rotate outer lock core, open lock.After lock was opened, screw key made the witness marker on it align with the anchor point that pulls key on the tapered end, and is pulled outwardly key, and fixedly the pellet shot from a slingshot of outer lock core slides to key teeth groove top and return along the key slope, can pull up key.The pellet shot from a slingshot of the utility model locking internal cylinder is at the afterbody of internal cylinder, the pellet shot from a slingshot of locking outer lock core is hidden on the internal cylinder, there is not any sensation when inserting key, theft is not known pellet shot from a slingshot information, can not be by the twisting key, feel the variation of exerting oneself and make master key and unblank, improved theftproof performance effectively.The position user of the position of key bit and what, screw will keep firmly in mind on the key, can the correct key unlocking of assembly during with anti-lost key.Because lock ﹠ key all is detachable structure, therefore, can arbitrarily split be ranked pellet shot from a slingshot and key bit and screw by oneself, prevent that by changing to adjust key bit information from exposing.
