A kind of location lock gall

Technical field

This utility model belongs to lock technology field, is specially a kind of location lock gall.

Background technology

The lock core of existing market, the basic machinery lock gall that adopts, the frame mode of machinery lock gall, determine the one_to_one corresponding pattern opened different locks with different keys.For intelligent lock core, market is also proposed some electronics lock galls successively.Although existing electronics lock gall can realize the intelligent management of key, but owing to, in design, range of application has significant limitation, part lock core is due to contour structures and the reason such as cooperation, it is impossible to use electronics lock gall.

Utility model content

For prior art Problems existing, the purpose of this utility model is in that design provides a kind of technical scheme positioning lock gall, its simple in construction, dependable performance.

Described one location lock gall, including lock gall shell and the lock core shell that is mated, lock gall shell is set in lock core shell, the lockhole that electron key inserts it is arranged in lock gall shell, the micro machine being connected with circuit board is also set up in lock gall shell, it is characterized in that the motor shaft of micro machine is fixedly installed cam, lock gall shell housing outside cam is symmetrical arranged two steel ball chutes, one or more axially movable steel balls are set in each steel ball chute, lock core shell inwall is correspondingly arranged two steel ball draw-in grooves；Cam rotation to its nose of cam with press inside steel ball coordinate time, the steel ball in outside be extruded part snap in steel ball draw-in groove；Cam rotation can axially free activity to steel ball time corresponding with inside steel ball to its cam recess.

Described one location lock gall, it is characterised in that the steel ball of two axial activities is set in each steel ball chute.

Described one location lock gall, it is characterized in that the motor shaft of micro machine is fixedly installed block of spiral, push rod it is equipped with above block of spiral, push rod inner end arranges push rod projection, block of spiral is correspondingly arranged one end to be wide mouth, one end is the random coil groove of slot, push rod projection and random coil groove are slidably matched, and push rod outer end is contacted with the block elasticity being fixed on lock gall shell by push rod spring and coordinates.

Above-mentioned a kind of location lock gall, when its electron key inserts lockhole, circuit board drives micro machine to open, motor shaft rotate drive cam rotation to its cam recess with inside steel ball to the time in of corresponding steel ball can axially free activity, in steel ball retraction lock gall shell automatically, lock gall rotates relative to lock core, drives opening structure opening lock master；Cam rotation to its nose of cam with press inside steel ball coordinate time, the steel ball in outside be extruded part snap in steel ball draw-in groove, lock gall can not rotate relative to lock core, it is impossible to opening lock master.This structural safety is reliable, small volume, uses scope wide.

Detailed description of the invention

This utility model is further illustrated below by way of Figure of description.

As shown in the figure, this location lock gall, including lock gall shell 2 and the lock core shell 1 that is mated, the lockhole that electron key inserts it is arranged in lock gall shell 2, the micro machine 10 being connected with circuit board is also set up in lock gall shell 2, the motor shaft 5 of micro machine 10 is fixedly installed cam 4, lock gall shell 2 housing outside cam 4 is symmetrical arranged two steel ball chutes 201, one or more axially movable steel balls 3 are set in each steel ball chute 201, lock core shell 1 inwall is correspondingly arranged two steel ball draw-in grooves 101；Cam 4 turn to its nose of cam 402 with press inside steel ball 3 coordinate time, the steel ball 3 in outside be extruded part snap in steel ball draw-in groove 101；Cam 4 turns to its cam recess 401 can axially free activity to steel ball time corresponding 3 with inside steel ball 3.As preferably, arranging the steel ball 3 of two axial activities in each steel ball chute 201.The motor shaft 5 of micro machine 10 is fixedly installed block of spiral 9, push rod 6 it is equipped with above block of spiral 9, push rod 6 inner end arranges push rod projection 601, block of spiral 9 is correspondingly arranged one end to be wide mouth, one end is the random coil groove 901 of slot, push rod projection 601 and random coil groove 901 are slidably matched, and push rod 6 outer end is contacted with block 8 elasticity being fixed on lock gall shell 2 by push rod spring 7 and coordinates.The width of rotation groove mouth width is for controlling block of spiral 9 and the slewing area of motor shaft 5.Described lock core shell 1 is different according to lockset, it is possible to be the shell of the various locksets such as safe-guard door lock, gourd lock, wood door lock, drawer-lock, ball catch.

Operation principle is as described below: when key inserts lock core, key bit, by push rod 6 sinciput, the wide mouth of push rod projection 601 to the random coil groove 901 of push rod 6, releases the partial turn space of block of spiral 9；In tapered end, single-chip microcomputer passes through electronically to identify key code simultaneously, the rotation of control micro electric machine 10, block of spiral 9 is driven to rotate in random coil groove 901 scope, motor shaft 5 drives block of spiral 9, cam 4 to rotate together, cam 4 turn to its cam recess 401 with inside steel ball 3 to steel ball time corresponding 3 can axially free activity, in steel ball 3 retraction lock gall shell 2 automatically, lock gall rotates relative to lock core, drives opening structure opening lock master；When extracting key, push rod 6 return under the action of the spring slides, push rod projection 601 is oppressed helicla flute 901 and is driven helicla flute to overturn, also cam 4 has just been driven to overturn, cam 4 turn to its nose of cam 402 with press inside steel ball 3 coordinate time, the steel ball 3 in outside be extruded part snap in steel ball draw-in groove 101, lock gall can not rotate relative to lock core, cannot opening lock master, use conveniently, safely.
