Abstract
The invention relates to an anti-theft lock with a protrusion at two sides of a return clutch shifting sheet structure assembly guide groove. An automatic return clutch shifting sheet structure assembly and a lock core hole cam structure assembly are arranged on a fixing plate (1); the automatic return clutch shifting sheet structure assembly includes an automatic return clutch shifting sheet (6), an automatic return guide groove (8) and a spring; one end of the spring is installed on the fixing plate (1) through a rivet; the other end of the spring is connected with the bottom of the automatic return clutch shifting sheet (6); one end of the automatic return clutch shifting sheet (6) is riveted onto the fixing plate (1) through a pin shaft; the other end of the automatic return clutch shifting sheet (6) is installed in the automatic return guide groove (8) through a pin (10); and protrusions (9) are arranged at two sides of the automatic return guide groove (8). The protrusion of the invention has the advantages of simple operation, simple assembly, being safe and reliable, as well as high adaptability. Lock core hiding and return steps are completed automatically; and based on effective cooperation of actions, a mechanical key can be pulled out when a door lock is unlocked and locked, and instant invisible protection for a mechanical lock core can be realized.
Description
Technical field
The present invention relates to a kind of lock with the lateral process of return clutch plectrum construction package gathering sill two, specifically
Say it is that one kind can make pin in gathering sill horizontally slip along domatic, drive baffle plate swing relative to fixed plate, hide or
Exposure lock core hole, reaches the device for being turned on and off lockset purpose.
Background technology
At present, existing mechanical anti-theft lock includes the mechanical lockhole of the electronic lock of biological identification technology, and lock core inserts key end
The outside of lock protective plate is exposed to, is provided using technology unlocking to robber and is turned round the possibility that spoon violence is unlocked, What is more
Robber's direct drawing lock core, lock gall are committed theft with reaching the almost opening door lock in the state of several noiselessness hence into interior, existing
There are many money invisible locksets in technology, though anti-theft effect preferably, cannot solve all the time the skill of moment automatic invisible after lock core is opened
An art difficult problem, and need to exclusively carry out training on installation and open exercise to instruct, operating procedure is more complicated, it is impossible to which quick popularization is big
It is many.
The content of the invention
For disadvantages described above, the invention provides a kind of return clutch plectrum construction package gathering sill both sides of lock
Projection, fixed plate is provided with self-return clutch plectrum construction package and lock core hole cam structure component, the self-return
Clutch plectrum construction package includes self-return clutch plectrum, self-return gathering sill and spring, and one end of spring passes through rivet
In fixed plate, the other end is connected with self-return clutch plectrum bottom, and one end of self-return clutch plectrum passes through
Bearing pin riveting is arranged in fixed plate, and the other end is arranged in self-return gathering sill by pin, self-return gathering sill
Both sides are conformed with；Lock core hole cam structure component includes boss, cam and keyhole, the cam neighboring with it is automatic
The inner edge of return clutch plectrum matches.
The both sides of self-return gathering sill of the present invention are provided with and form domatic projection with ecto-entad；The projection
Domatic degree ≈ fixed plates thickness.
After above technical scheme, the present invention has simple to operate, and assembling is simple, and insurance is reliable, and suitability extensively waits special
Point, lock core is stealthy and reset process is and is automatically performed, and the step of without the need for increasing open and close door, effectively overcomes previous generations hidden
The fault of construction of shape lockset（The failure of key can be blocked when forgetting that manually stealthy or automatic time delay is stealthy）, cause anti-theft effect
The drawbacks of difference.While effective interoperation of the invention realizes that open and close door lock extracts mechanical key, the wink to mechanical lock is completed
Between stealthy protection.

Specific embodiment
According to Fig. 1, Fig. 2, a kind of return clutch plectrum construction package gathering sill both sides of lock of the invention
Projection, fixed plate 1 is provided with self-return clutch plectrum construction package and lock core hole cam structure component, the self-return from
Closing plectrum construction package includes self-return clutch plectrum 6, self-return gathering sill 8 and spring, and one end of spring passes through rivet
In fixed plate 1, the other end is connected with the bottom of self-return clutch plectrum 6, and one end of self-return clutch plectrum 6 leads to
Cross bearing pin riveting to be arranged in fixed plate 1, the other end is arranged in self-return gathering sill 8 by pin 10, and self-return is led
Both sides to groove 8 are conformed with 9；Lock core hole cam structure component includes boss 13, cam 5 and keyhole 7, outside the cam 5
Periphery matches with the inner edge of self-return clutch plectrum 6.
Cam of the present invention 5 due to the effect of spring elongation, when key band moving cam 5 rotates, its neighboring with it is automatic
The inner edge of return clutch plectrum 6 matches.When cam 5 is in horizontality, spring is in extended state, self-return clutch
The lower end of plectrum 6 is moved in fixed plate 1 outward flange, and pin 10 slides to the domatic least significant end of projection 9, and lock core hole is in unlatching
State；When cam 5 is in plumbness, spring is in contraction state, and the lower end of self-return clutch plectrum 6 is moved to fixation
1 inner side on plate, pin 10 slides to the domatic most significant end of projection 9, and lock core hole is closed.
When key is rotated, the edge of cam 5 is in close contact with the inner edge of self-return clutch plectrum 6, the edge of cam 5
The extension spring of high point drive self-return clutch plectrum 6, stored energy, the pin of the lower end of self-return clutch plectrum 6 is along certainly
Dynamic the domatic of the both sides of return gathering sill 8 is moved from inside to outside in self-return gathering sill 8, and pin 10 to domatic low side slides, domatic
The difference in height of highs and lows be approximately equal to the thickness of fixed plate 1, due to domatic effect, the height of pin 10 is beyond solid
The height of the another side of fixed board 1 fixes baffle plate, because baffle plate is fixed in the supporting role in the section of mechanical key, in case backstop
Plate swings, and exposes lock core, and now keyhole is in opening.
When key is extracted, spring releases energy, and pin 10 is moved inward in self-return gathering sill 8, bounces back into slope
In face projection 9, the now height of the another side of the height≤fixed plate 1 of pin 10, baffle plate resets block keyhole rapidly, hides
Lock core, keyhole is closed.
According to Fig. 3, a kind of projection of the return clutch plectrum construction package gathering sill both sides of lock of the invention,
The both sides of the self-return gathering sill 8 are provided with and form domatic projection 9 with ecto-entad.
According to Fig. 4, a kind of projection of the return clutch plectrum construction package gathering sill both sides of lock of the invention,
The thickness of the domatic degree ≈ fixed plates 1 of the projection 9.
