Abstract

The utility model relates to a theft-proof lock core, which belongs to the technical field of an electricity controlled theft-proof lock and is driven by a motor. A Horizontal lock rod is driven by a worm wheel, a worm rod, an eccentric shaft and a connecting rod, and a cone block is fixed on the horizontal lock rod. A slide way is arranged on the cone block and a vertical lock rod is arranged in the slide way through a slide block, which enables the vertical lock rod to do up-and-down movements. The cone difference of the cone block is used, which enables open and close operations of three horizontal and vertical locking points to be achieved. The utility model has the advantage of safety, and can be used for the fields of theft-proof doors, safety cabinets, file cabinets, cipher boxes, coffers, office doors, etc., and high-tech door control means, such as electric control, etc. can be achieved.

Description

The electric burglar-proof lock heart

The utility model is the lock cylinder device of electromechanical, is widely used in gates such as family security door, safety cabinet, file cabinet, hotel, office, national treasury, belongs to the theftproof lock field with electric control.

Existing home security door lock generally adopts cores such as lever type, spring-latch, shell fragment, pellet shot from a slingshot, usually install a tapered end, the door lock of two tapered ends is also arranged or add mechanical code lock, its shortcoming is to use key switch to be easy to generate key lock in door, inconvenient operation when using mechanical code lock to be used in security door glazed thread deficiency, more than existing simple door lock assembly, theftproof performance is poor, easily stolen.

The purpose of this utility model is to realize like this.

A kind of electric burglar-proof lock heart, it is characterized in that the worm screw 2 on 3 in the direct current generator, by worm screw 2 and worm gear 1 interlock transmission, 4 is worm-wheel shaft, eccentric shaft 5 on the worm gear 1 is connected with connecting rod 6, and for being rotatably assorted, the fork 9 usefulness bearing pins of the other end of connecting rod 6 and horizontal locking bar 8 flexibly connect, two taper pins 19 of awl piece 20 usefulness are fixed on the horizontal locking bar 8, on the conical surface up and down of awl piece slideway K are arranged ₁, K ₂, slide block 7 devices are at slideway K up and down ₁, K ₂In be slidingly matched, vertical up and down locking bar 21 is connected with slide block 7 respective fixation up and down, the horizontal guide pin bushing of horizontal locking bar 8 device about cone 10,11 is for being slidingly matched, the vertical guide pin bushing 13,14,15,16 of vertical up and down locking bar 21 devices is also for being slidingly matched, one end of horizontal locking bar is inserted in the doorframe lockhole 12, and vertical up and down locking bar is inserted in respectively in the E, F hole of doorframe 17.

The utility model has the advantages that: 1, novel structure, advanced person, electromechanical can be realized the opening and closing action of level, vertical three locks point simultaneously; 2, safe and reliable, core is contained in the door, and the no tapered end of door table does not use key, is easy to realize the automatic electronic gate, uses watchdog circuit and encrypts, and can not decode; 3, this mechanism has self-locking property.

Further specify operating principle of the present utility model below in conjunction with accompanying drawing:

Drive motors 3 is by worm screw 2, worm gear 1 deceleration transmission, and eccentric shaft 5 drivening rods 6 rotate, and horizontal locking bar 8 passes through guide pin bushing 10,11 horizontal M to slip, when connecting rod 6 rotates to A ₂During the position, promptly slide block 7 passes through slideway K up and down ₁, K ₂Move to low level S by high-order D, vertical up and down locking bar 21 is given up the throne, and doorframe 17 and door 18 are thrown off, and horizontal locking bar 8M gives up the throne to displacement simultaneously, this moment horizontal locking bar Z end, vertical E, F lock point is thrown off, and is unlocking condition, on the contrary as horizontal locking bar N during, i.e. A to displacement ₂The position rotates to A ₁During the position, promptly horizontal locking bar 8, awl piece 20 are by slideway K ₁, K ₂Be moved to high-order D by low level S, vertical up and down locking bar 21 carries are inserted in the doorframe lockhole, and the Z of horizontal locking bar 8 end inserts in the lockhole 12 simultaneously, is locking-in state.For guaranteeing the accurate position of lock point, horizontal locking bar Z end device microswitch locate at antitheft door device ball lock 22, and internal control is used after entering the room, to guarantee the mobility and the reliability of latch mechanism as Stroke Control.The utility model core is by the reciprocating motion of eccentric rod gear, the awl that awl piece displacement on the horizontal locking bar 8 is produced is poor, realize up and down the insertion of vertical locking bar and withdraw from action, horizontal locking bar Z holds the insertion of lock tube 12 and withdraws from and depends on eccentric throw, uses this mechanism to realize that simultaneously door lock is vertical, the opening and closing operating principles of three lock points of level.
