As for the mechanical lock and the key, different password teeth on the key push the corresponding sliding pins to move and be separated from the core housing, thus opening the lock, achieving good anti-theft effect and having more convenient use; the password teeth have different thickness and can be installed alternatively, therefore, the user can still open the lock in person even if the key is lost.
Description
Technical field
The present invention relates to a kind of lock and key, relate in particular to a kind of mechanical lock and key.
Background technology
At present, most mechanical lock comprise dead bolt, lock, lock core assembly, external-open rotation hub, in open rotation hub and interlinked mechanism, the lock core assembly comprises core body and core retainer plate, and keyhole is set on the core body, when inserting key in keyhole, screw key drives the core body rotation and reaches the purpose of unblanking.The mechanical lock and the key of this structure have the following disadvantages: one, the supporting use of mechanical lock ﹠ key, in case key loss, the user can't open mechanical lock, must look for the unlock staff of specialty just can unblank, and mechanical lock can't use because of losing of matched key; Must just can unblank by screw key when two, inserting key, use inconvenience.
Therefore, need transform existing mechanical lock and key, under the situation of key loss, the user also can unblank, and can avoid mechanical lock can't use because of losing of matched key simultaneously, and more convenient when unblanking.
Summary of the invention
In view of this, the invention provides a kind of mechanical lock and key, under the situation of key loss, but user's lock in person even if has avoided mechanical lock can't use because of losing of matched key simultaneously, and more convenient when unblanking.
Mechanical lock provided by the invention, comprise that lock core assembly and external-open rotate hub, described lock core assembly comprises core body and core retainer plate, keyhole is set on the core body, described core retainer plate is enclosed within on the core body with the mode single-degree-of-freedom of longitudinal sliding motion, two sliding pins are set in the core body at least, described sliding pin slides along the relative core body single-degree-of-freedom of its axis, the vertical distance at sliding pin two ends equates with the size of core body in the sliding pin glide direction, the projection of sliding pin outer circle diameter in setting puts in keyhole, the corresponding locking hole that is provided with of core retainer plate with the two ends of sliding pin; Rotation external-open rotation hub can drive core retainer plate and slide on core body, and the core retainer plate end is provided with back-moving spring, and the restoring force of described back-moving spring is opposite with the driving force direction that external-open rotates hub;
Also comprise stage clip, the pressure of described stage clip is pressed on the sliding pin along the glide direction of sliding pin.
Further, the projection of described different sliding pins is provided with the position difference along its axis;
Further, described sliding pin is distributed in the left and right sides of keyhole, totally six;
Further, described external-open rotation hub and core retainer plate are by the edge cam respective outer side edges;
Further, the cross section of described projection is an arc transition;
Further, the interface of described edge cam is a spherical transition.
The present invention also provides a kind of key of opening mechanical lock, the described setting on the key and the corresponding password tooth of different projections, and the corresponding projection of password tooth promotion made sliding pin release lock tieholen when key inserted.
Further, described password tooth is arranged on the key removably;
Further, described key comprises key main body and key handle, has password tooth mounting groove on the key main body, and described password tooth is embedded in the password tooth mounting groove of key main body, and the key main body is inserted in the key handle and by bolt and locked;
Further, the front end of the front end of described key main body and password tooth is taper.
Beneficial effect of the present invention is: mechanical lock of the present invention and key, at least two sliding pins that slide along the relative core body single-degree-of-freedom of its axis are set on core body, projection is set on the sliding pin, under the pressure effect of the stage clip that is provided with on the projection, each sliding pin one end puts in the corresponding locking hole with different length respectively, different on the key password teeth promotes corresponding projection and moves and make sliding pin release lock tieholen when inserting key, reach and unblank, password teeth different when unblanking must be corresponding with corresponding projection, so good anti-theft effect; Insert key, rotating handles just can be unblanked, and need not screw key, uses more convenient; Password transverse tooth thickness degree on the key has nothing in common with each other, and interchangeable installation, the user only need remember the thickness of each password tooth, even when key loss, the user only needs just can unblank according to the thickness installation password tooth of original different password teeth on the key new, need not professional unlock staff and unblank, avoided mechanical lock can't use simultaneously because of losing of matched key.
