Description

Stealthy lock core

Affiliated technical field

The present invention relates to lockset and especially relate to the stealthy lock core that is used to open lockset

Background technology

Traditional lock core is made up of lock core body, key at present; Wherein key is made up of spoon body, the shank of the key, and mostly the shape of the shank of the key is circular or square and is staight shank that both spoon body and the shank of the key were on same straight line; Hand is being pinched the shank of the key during use; The spoon body is inserted in the keyhole, open the lock core of lockset, such making skill lock core key jack down is exposed to the lock tube outside.Along with the progress of society, growth in the living standard, various high-grade household products get into common people house; Incident thievery frequently takes place; Thereby various locks arise at the historic moment, but are hidden in the lockset in the lock tube for a kind of lock such as lock core, make the staight shank key to use.

Summary of the invention

The object of the present invention is to provide a kind of stealthy lock core that is used for lock.Be that the lock core key jack is hidden in the lock tube; Key is arranged to L shaped shape; And the spoon body can rotate in the shank of the key circular hole; Insert the spoon body in the key hole earlier, at this moment lock core marble is in opening, promotes the stealthy lock core of a kind of theftproof lock that rotating guide drive lock in-core cover, spoon body synchronously rotate again.

For realizing that above-mentioned purpose the present invention can take following technical proposals:

Described lock core body is mechanical billiard structure (or magnetic bullet structure), and it comprises cover in lock core sleeve, the lock core, and offers several pellet shot from a slingshot perforation; Built-in spring marble; Cover one end is provided with dead bolt in the lock core, and offers circular hole rotating guide is installed, and the cover other end is offered key hole in the lock core.

Describedly L shapedly turn the handle screw key it comprises a spoon body, the shank of the key.Spoon body one end offers corresponding to the lock core body pellet shot from a slingshot and arranges the different tartar (or cylindrical shape magnetic spoon body) of height, and the other end is arranged to cylinder, and offers perforation corresponding to pin; The shank of the key one end side of being body (or cylinder); Offer circular hole corresponding to spoon body cylinder, offer pin road groove at the shank of the key circular hole place, offer perforation with the shank of the key circular hole parallel direction; And spring steel ball is set, offer perforation for being convenient for carrying at the shank of the key other end hand place of pinching.

Described spoon body barrel portion inserts in the shank of the key circular hole; Constitute L shaped shape through pin, pin road groove, the shank of the key circular hole; And the spoon body can rotate in the shank of the key circular hole, and spoon body location stays steel ball to realize through giving, and makes the L shaped handle screw key that turns to insert smoothly in the lock core body key hole.

Beneficial effect of the present invention: key is provided with L shaped structure, spoon body can be inserted in the key hole that is hidden in the lock tube internal lock core body smoothly, hand pinches the shank of the key and turns the shank position during use; The spoon body is inserted in the lock core key jack from the slot that is opened on the lock tube sidewall; At this moment lock core marble is in opening, rotating lock tongue place rotating guide, and cover and spoon body synchronously rotate in transmission dead bolt, the lock core; Dead bolt separates with snap close; Open lockset, the closed lockset of counter-rotation rotating guide, very easy to use.

Described transmission device is a rotating guide, also can be spring or the gear that has hardness.

The specific embodiment

Stealthy lock core of the present invention, it comprises lock core body 1, the L shaped handle screw key 8 that turns.Lock core body 1 comprises lock core sleeve 5, cover 4 in the lock core, and offer several pellet shot from a slingshot perforation, and cover 4 one ends are provided with dead bolt 3 in the interior placement spring marble 7, lock core, and offer circular hole rotating guide 2 is installed, and the other end is offered key hole 6.The L shaped handle screw key 8 that turns comprises spoon body 9, the shank of the key 10, and spoon body 9 one ends offer key tooth flower 12 corresponding to lock core body pellet shot from a slingshot 7; The other end is arranged to cylinder 13, and offers perforation 15, the shank of the key 10 1 end side of being bodies corresponding to pin 22; Offer the shank of the key circular hole 16 corresponding to spoon body cylinder 13, offer pin road groove 14, offer perforation 23 in the shank of the key circular hole parallel direction corresponding to pin 22; The interior spring steel ball 17 of placing holds the hand place of pinching to offer perforation 11 for being convenient for carrying at the shank of the key in addition, and spoon body cylinder 13 inserts in the shank of the key circular holes 16; Pin 22 is combined closely with corresponding perforation 15, be combined into L shaped shape through 14 spoons of bodies 9 of pin road groove and the shank of the key 10, and a spoon body 9 can rotate in the shank of the key circular hole 16; Spoon body 9 positioning of rotating are realized by steel ball 17, make the L shaped handle screw key 8 that turns insert key hole 6 smoothly, and at this moment lock core body pellet shot from a slingshot 7 is in opening; Manually rotation Anti-theft cap 18 drives shop bolt 21, rotating guide 2 is done rotation; Cover 4 and spoon body 9 synchronously rotate along 20,19 directions in transmission dead bolt 3, the lock core, and dead bolt 3 is separated with snap close 24 with closed.
