Description

A kind of electronic lock

Technical field

The present invention relates to a kind of lockset, more particularly to a kind of electronic lock.

Background technology

At present, the door lock sold on market can substantially be divided into two kinds, i.e. mechanical lock and electronic lock.So-called mechanical lock is Refer to that, to be mechanically connected between each component in whole lock body, this kind of door lock is widely used in life；Wherein, mechanical lock The usual structure of unlocking apparatus is to include the shifting block between interior plectrum, outer plectrum and inside and outside plectrum；Although mechanical lock need not It is powered, but it has the drawback that security is poor, and the key for being mainly manifested in unlatching mechanical lock is easy to replicate.Therefore, it is existing Mechanical lock still can not meet people life needs, it would be highly desirable to improve.Electronic lock then by Password Input come control circuit or Chip operation (access control system), so as to the closure of control machinery switch, completes unlocking, the electronic product of locking task, but It is of the prior art by after access control system, further dead bolt and latch bolt is respectively moved in lock body respectively Portion, could realize the unlatching locked, and latch bolt generally just can open by being turned the handle in prior art, and dead bolt is then by electricity Road control section is driven it and is moved in lock body by key, such structure exist for electric power according to Bad property is too strong and operates more troublesome shortcoming.

For this purpose, Patent No.：200910248650.7, patent name is in the patent document of " arrangement of clutch of electronic lock " Disclose following technical scheme：Including outer plectrum, outer shifting block, interior shifting block, interior plectrum, be followed successively by outer plectrum outer shifting block, interior group Block and interior plectrum, it is characterised in that the cylinder being provided centrally with handle through hole of described outer shifting block, the side of outer shifting block It is provided with an outer rib, the groove on an outer rib and outer shifting block is domatic a, rib outward in rotating clockwise on direction for groove Exterior bayonet slot of the outer pin block of lower section corresponding to the outer plectrum；Put through hole in described interior shifting block center to arrange in outer shifting block On cylinder, respectively interior clockwise a rib, interior two rib and the interior Rhizoma Sparganii of the side of interior shifting block, the cylindricality below interior Rhizoma Sparganii Snap in groove corresponds to described groove, and the interior pin block of the top of interior Rhizoma Sparganii is arranged in the inner card cage of the interior plectrum, interior The side of Rhizoma Sparganii is provided with the limited post corresponding to interior Rhizoma Sparganii；Gap is provided between outer shifting block and interior shifting block, is arranged in gap There is the conductive sheet by solenoid actuated；Also include the dead bolt connecting rod of lock body, dead bolt and dead bolt axle connection, and with dead bolt phase The left side from locking plate mechanism even constitutes, left self-locking from locking plate and the right side from locking plate, a left side by from locking plate mechanism from locking plate from locking plate Left groove, the bracket groove of right-angled trapezium and the right groove of U-shaped are provided with piece.

When shutting, handle or during outer handle in upper lift rotates counterclockwise outer shifting block, outer shifting block to above-mentioned technical proposal An outer rib press dead bolt connecting rod, now, the pin on dead bolt by a left side from the right groove of locking plate right-angled trapezium in right-angled trapezium Groove is moved in the left groove of U-shaped, and dead bolt protrudes horizontally up lock body, is completely shut；During unlocking, in the case where having permission, on lock body Electromagnet is powered, and promotes conductive sheet, leaves gap of the conductive sheet between outer shifting block and interior shifting block；Then, interior handle is pushed Or outer handle, outer shifting block is rotated clockwise, then, the snap in cylindrical groove below interior shifting block falls into the groove of outer shifting block It is interior, outer shifting block is connected with interior shifting block by snap；With rotating clockwise for interior handle or outer handle, interior shifting block it is interior One rib is stirred clockwise from locking plate, makes from locking plate to rotate counterclockwise hook upwards to move the right side from locking plate, and the right side drives a left side from locking plate Move from locking plate, and then the pin on dead bolt is moved in right groove through bracket groove from the left groove of locking plate by a left side, at the same time interior shifting block Interior two rib rotate clockwise and stir dead bolt connecting rod, dead bolt is moved horizontally in lock body, complete to unlock.

Above-mentioned patent application document, its operation principle：When locking a door, by rotating counterclockwise handle dead bolt can just stretched Go out lock body；During unlocking, latch bolt component and bolt component are connected as a single entity, and by rotating clockwise hand-drive latch bolt component and a lock Tongue component, makes dead bolt be moved in lock body, but such structure is excessively complicated, and assembling and maintenance are more difficult.
