Abstract
The utility model relates to a back locking structure of a door lock. The back locking structure of the door lock comprises a face plate, a handle and a drive plate linking and matching with the handle, and is characterized by further comprising a knob, an ejector rod and a drive mechanism, the knob drives the ejector rod to extend and retract via the drive mechanism, and a clamping groove for clamping the ejector rod is formed in the drive plate. By the aid of the technical scheme, the back locking structure of the door lock can well prevent undesirables from unlocking by rotating the handle from a peephole, and is high in ant-theft coefficient.
Description
Technical field
The utility model relates to field of lockset, particularly a kind of door lock back locking structure.
Background technology
Existing a kind of door lock includes panel, is arranged on the handle on the panel, is provided with the drive plate that is linked with handle in the panel, is provided with lock core in the panel, and drive plate and lock core are linked, rotate handle through the work of drive plate control lock core realize unblanking, locking.
But, the door lock of this structure, some undesirables reach the purpose of unblanking thereby can stretch into the rotation handle from the opal on the door body by special tool, therefore, and this door lock, its antitheft coefficient is low.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model provides a kind of door lock back locking structure, can prevent well that the undesirable from rotating handle from opal and unblanking its antitheft coefficient height.
The technical solution of the utility model: a kind of door lock back locking structure, the drive plate that includes panel, handle, is linked with handle, it is characterized in that: also include knob, push rod, transmission mechanism, it is flexible that described knob drives push rod through transmission mechanism, and described drive plate is provided with the draw-in groove that snaps in for push rod.
Adopt technique scheme, can pass through turning knob, the control push rod snaps in draw-in groove, and at this moment, handle can not rotate namely and can not unblank, when unblanking, need first turning knob to make push rod and exact separation, therefore, the door lock back locking structure of this structure, can prevent well that the undesirable from rotating handle from opal and unblanking its antitheft coefficient height.
Further setting of the present utility model: described transmission mechanism includes driving member, described driving member and knob are linked, knob drives driving member and rotates, described driving member is provided with circular-arc slotted eye, described push rod is provided with STATEMENT OF FEDERALLY SPONSORED, and described STATEMENT OF FEDERALLY SPONSORED places in the described slotted eye.
Adopt above-mentioned further setting, when transmission, knob drives the driving member rotation, and it is flexible that the circular-arc slotted eye on the driving member just can drive push rod through STATEMENT OF FEDERALLY SPONSORED, and the transmission mechanism of this structure is simple in structure, installation, easy to process.
Further setting more of the present utility model: described knob is provided with drive link, described drive link is provided with the location division, the cross section of described location division is rectangle, described slotted eye is semicircle, be arranged with spring on the described location division, described spring includes two parallel sides, and two parallel sides of spring are conflicted with the two opposite side walls of location division respectively.
Adopt above-mentionedly further to arrange, the each rotation of knob is set to 90 degree again, and knob just changes, reverses once, push rod or be positioned at draw-in groove, or be positioned at outside the draw-in groove, can conveniently control like this.
Further setting of the present utility model: be provided with positioning seat in the described panel, described positioning seat is provided with guide groove, described push rod places in the guide groove, described guide groove is provided with gland, described gland is fixedlyed connected through screw with positioning seat, and corresponding screw position is provided with chute along its flexible direction on the push rod.
Adopt above-mentionedly further to arrange, the guide groove of setting and gland can be so that push rod is flexible can not to be offset, thereby make push rod flexible more reliable.
Further setting more of the present utility model: described spring also includes for the fillet that connects its two parallel sides, and described spring is " U " font, and described guide groove two bottom sides is provided with bayonet socket, and described spring two parallel sides embed in the bayonet socket.
Adopt above-mentioned further setting again, the spring set-up mode of this structure, rational in infrastructure, simple, easy to process.
