Abstract
The invention relates to a protrusion at two sides of a return clutch shifting sheet structure assembly guide groove of an anti-theft lock. 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 projection of return clutch plectrum element of construction gathering sill both sides of lock, specifically one can make pin in gathering sill horizontally slip along domatic, baffle plate is driven to swing relative to fixed head, hide or expose lock core hole, reaching the device opened or close lockset object.
Background technology
At present, existing mechanical anti-theft lock comprises the mechanical lockhole of the electronic lock of biological identification technology, lock core inserts the outside that key end is exposed to lock protective plate, provide operation technique to robber unblank and turn round the possibility that spoon violence unblanks, What is more robber's direct drawing lock core, lock gall is to reach almost opening door lock under several noiseless state, thus enter indoor and commit theft, many moneys invisible lockset in prior art, though anti-theft effect is better, but the technical barrier that lock core opens rear automatic invisible instantaneously cannot be solved all the time, and need to carry out training on installation specially and open exercise instructing, operating procedure is more complicated, masses can not be popularized fast.
Summary of the invention
For above defect, the invention provides a kind of projection of return clutch plectrum element of construction gathering sill both sides of lock, fixed head is provided with self-return clutch plectrum element of construction and lock core hole cam structure assembly, described self-return clutch plectrum element of construction comprises self-return clutch plectrum, self-return gathering sill and spring, one end of spring is arranged on fixed head by rivet, the other end is connected with bottom self-return clutch plectrum, one end of self-return clutch plectrum is arranged on fixed head by bearing pin riveted joint, the other end is arranged in self-return gathering sill by pin, the both sides of self-return gathering sill are provided with projection, lock core hole cam structure assembly comprises boss, cam and keyhole, and the inner edge of described cam neighboring and self-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 thickness of the domatic degree ≈ fixed head of described projection.
After adopting above technical scheme, the present invention has simple to operate, assembling is simple, insurance is reliable, the features such as suitability is wide, lock core stealth and reset process are and automatically complete, without the need to increasing the step of open and close door, effectively overcome previous generations invisible lockset fault of construction (forget manually stealthy or automatic delayed is stealthy time can block the fault of key), cause the drawback of anti-theft effect difference.The effective interoperation of the present invention realizes while open and close door lock extracts mechanical key, completing the moment stealth protection to mechanical lock.

Detailed description of the invention
According to Fig. 1, shown in Fig. 2, the projection of the return clutch plectrum element of construction gathering sill both sides of a kind of lock of the present invention, fixed head 1 is provided with self-return clutch plectrum element of construction and lock core hole cam structure assembly, described self-return clutch plectrum element of construction comprises self-return clutch plectrum 6, self-return gathering sill 8 and spring, one end of spring is arranged on fixed head 1 by rivet, the other end is connected with bottom self-return clutch plectrum 6, one end of self-return clutch plectrum 6 is arranged on fixed head 1 by bearing pin riveted joint, the other end is arranged in self-return gathering sill 8 by pin 10, the both sides of self-return gathering sill 8 are provided with projection 9, lock core hole cam structure assembly comprises boss 13, cam 5 and keyhole 7, and the inner edge of described cam 5 neighboring and self-return clutch plectrum 6 matches.
Cam 5 of the present invention is due to the effect of spring elongation, and when key band moving cam 5 rotates, the inner edge of its neighboring and self-return clutch plectrum 6 matches.When cam 5 is in level, spring is in extended state, and the lower end position of self-return clutch plectrum 6 moves to the outward flange of on fixed head 1, and pin 10 slides to the domatic least significant end of projection 9, and lock core hole is in opening; When cam 5 is in plumbness, spring is in contraction state, and the lower end position of self-return clutch plectrum 6 moves to the inner side of on fixed head 1, and pin 10 slides to the domatic most significant end of projection 9, and lock core hole is in closed condition.
When rotating key, the edge of cam 5 and the inner edge close contact of self-return clutch plectrum 6, the height point at cam 5 edge drives self-return clutch plectrum 6 extension spring, stored energy, the pin of self-return clutch plectrum 6 lower end outwards moves in self-return gathering sill 8 along the domatic of self-return gathering sill 8 both sides, pin 10 slides to domatic low side, the difference in height of domatic highs and lows approximates the thickness of fixed head 1, due to domatic effect, the height that the height of pin 10 exceeds fixed head 1A face fixes baffle plate 4, baffle plate 4 is fixed in supporting role due to the cross section of mechanical key, in case baffle plate 4 swings, expose lock core, now keyhole is in opening.
When extracting key, spring releases energy, and pin 10 moves inward in self-return gathering sill 8, bounce back in domatic projection 9, now the height in the height≤fixed head 1A face of pin 10, baffle plate resets rapidly and blocks keyhole, hide lock core, keyhole is in closed condition.
According to Fig. 3, the projection of the return clutch plectrum element of construction gathering sill both sides of a kind of lock of the present invention, the both sides of described self-return gathering sill 8 are provided with and form domatic projection 9 with ecto-entad.
According to Fig. 4, the projection of the return clutch plectrum element of construction gathering sill both sides of a kind of lock of the present invention, the thickness of the domatic degree ≈ fixed head 1 of described projection 9.
