Abstract

The utility model provides an electronic door lock which can control the position of a lock tongue at any time and is suitable for a glass door. A step on the tail of a main lock tongue in a lock core is hooked by a draw hook, and a draw hook switch is arranged on the rear end of the draw hook. A lock tongue control switch is arranged on the draw hook switch. When the lock tongue control switch is rotated outside a lock body, the main lock tongue can be contracted in the lock core. After a glass door is opened, when the glass door does to-and-fro swing, the glass door can not be collided by the main lock tongue.

Description

Electronic lock

The utility model has related to a kind of electronic lock that can regulate latch bolt position.

Electronic lock is convenient and swift, has functionalized function, and the repetition rate of coding is low, and can make key by oneself, is subjected to liking of people.Electronic lock generally all adds packed battery, adopts many dead bolts structure, so volume is bigger, and after door was opened, dead bolt recovered overhanging state again, so how electronic lock is is just installed and used on glass door and become problem.Lock body lock core lock storehouse is difficult for installing on glass door, and overhanging dead bolt is very easily broken another that swing back and forth and fanned corresponding glass door.So general mode of locking a door that adopts high photoelectricity gate control system of price or the extremely inaesthetic door knob of employing to add iron chains with regard to abandoning.

The purpose of this utility model be design a kind of simple in structure, reliable, can control latch bolt position, be suitable for the electronic lock that glass door uses.

The technical solution of the utility model is as follows: electronic lock has interior lock body, outer lock body, lock core, the lock storehouse, control circuit, the unblank micro machine and the mechanical system of unblanking are housed in lock core, main dead bolt afterbody is equipped with drag hook in lock core, the drag hook front end is hook-shaped, contact for movable with the right flank of the step of main dead bolt afterbody, the rear end of drag hook is equipped with one and is lifted the drag hook switch, lifting the drag hook switch contacts for movable with the medial surface of drag hook, lift the dead bolt gauge tap vertically is housed on the drag hook switch, outside lock body was exposed in the other end of dead bolt gauge tap passed, be equipped with at the upper side of main dead bolt leading section and remove pin, the left surface of removing pin contacts for movable with the right flank of the step of locking tongue.Two sides, front and back at lock core is equipped with front plate and rear plate respectively, and the area of each clamping plate also is equipped with lock storehouse front plate and lock storehouse rear plate respectively greater than nipped plug face on the two sides in lock storehouse, and the clamping plate area is greater than nipped lock storehouse face.Behind the location, relevant position of door, locate clamping plate separately respectively in lock core and lock storehouse again, lock core, lock storehouse is fixed on the door by clamping plate with bolt fastener again.

The technical solution of the utility model is simple, just can make main dead bolt no longer overhanging under the state that opens the door by rotation dead bolt gauge tap, because in the main dead bolt withdrawal lock core, removing pin will lock tongue and also push in the lock core simultaneously, do not need to move specially again and lock tongue and remove button, easy to use, reliable, reached the purpose that electronic lock uses on glass door.Remove pin and replaced forcing to regain the rotational structure of locking tongue, the number of packages amount reduces in addition, has reduced weight and cost.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the outside drawing outdoors of the utility model electronic lock.

Fig. 2 is the interior outside drawing of the door of electronic lock.

Fig. 3 is the lock core cut-away view.

Embodiment of the present utility model sees that from Fig. 11 is the lock core front plate, and 4 are lock storehouse front plate, 2 is outer lock body, and 3 are the lock storehouse, and 5 remove button for locking tongue among Fig. 2,6 is the dead bolt gauge tap, 7 is interior lock body, and 8 is the lock core rear plate, and 9 are lock storehouse rear plate, dotted portion is a cut-out on the glass door among the figure, lock core and lock storehouse are contained in the cavity, and the forward and backward clamping plate made from metal or plastics respectively on left and right glass door leaf are fixed lock core and lock storehouse then, twist the jail with bolt system again.11 for locking tongue in Fig. 3, and 12 is finger, and 13 is main dead bolt, and 14 is the pick-proof tongue, and 15 are the ratchet of unblanking, and 16 is fan-shaped turbine, and 17 is scroll bar, and 18 is micro machine, and 19 is castle wheel, and 20 is shifting block, and 21 is drag hook, and 22 for lifting the drag hook switch.Dead bolt gauge tap 6 on the rotary locking cylinder rear plate, lift the drag hook switch with regard on lift, drag hook makes drag hook hook end break away from main dead bolt step, dead bolt is protruding; When opening the door in master's dead bolt indentation lock core, when rotating the dead bolt gauge tap round about, main dead bolt step is hooked in the drag hook end, dead bolt then remains in the lock core, because finger 12 drives that make on the main dead bolt that move inward of main dead bolt are locked in the tongue 11 retraction lock cores, needn't pull again and lock tongue and remove button 5 this moment, when glass door moves back and forth, dead bolt and door leaf can not take place collide.
