Abstract
A kind of prerotation vane of self-lock, described prerotation vane has the lockhole stretched out for the main lock core of self-lock, safe lock cylinder, described prerotation vane also installs movable part, the collision bead of described movable part and described self-lock is just right, described movable part is connected with elastic telescopic mechanism, and during original state, the elastic force of elastic telescopic mechanism is greater than the stress value triggering described collision bead action.The problem the invention provides a kind of insurance of effectively avoiding can not linking when closing, normally cannot unblanking when opening, the prerotation vane of self-lock of lifting reliability.
Description
Technical field
The present invention relates to a kind of self-lock.
Background technology
Existing self-lock, except lock core, lock body and lock housing, lock core comprises main lock core and safe lock cylinder, also on lock body, be provided with collision bead, in closing process, when collision bead and doorframe touching, in linkage safe lock cylinder can be stretched out, during opening process, when doorframe is separated with collision bead, can unlock for safe lock cylinder; Problems existing is: in closing process, time distant between described doorframe and lockset, cannot effectively touch described collision bead, cause realizing insurance function; In opening process, between described doorframe and lockset during close together, doorframe is easy and collision bead is stuck, causes normally unblanking.
Summary of the invention
In order to the insurance that can not link when overcoming closedown that existing self-lock exists, open time problem, the reliability that cannot normally unblank poor deficiency, the invention provides a kind of effectively avoid cannot normally unblanking when can not link insurance, unlatching when closing problem, lifting reliability the prerotation vane of self-lock.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of prerotation vane of self-lock, described prerotation vane has the lockhole stretched out for the main lock core of self-lock, safe lock cylinder, described prerotation vane also installs movable part, the collision bead of described movable part and described self-lock is just right, described movable part is connected with elastic telescopic mechanism, and during original state, the elastic force of elastic telescopic mechanism is greater than the stress value triggering described collision bead action.
Further, described movable part is portable plate, described portable plate is curved, described portable plate is positioned at the installing hole of prerotation vane, and the cambered surface of described portable plate exceeds described prerotation vane place plane, described portable plate and one end are conflicted, and the other end of described torsion spring is arranged on bearing pin, and described bearing pin is arranged on the bottom of described prerotation vane.
The bottom of described portable plate is installed in rotation on described bearing pin.This form of structure, is convenient to portable plate location.
Further again, described movable part is motion stops, in the installing hole of described prerotation vane, gathering sill is installed, described motion stops can telescopically be positioned at described gathering sill up and down, piston rod is installed in the bottom of described motion stops, and described piston rod stretches out the through hole of the bottom of described gathering sill, described upper cover of piston rod shock mount, setscrew nut is installed in the lower end of described piston rod, and the external diameter of described setscrew nut is larger than described through hole.
Beneficial effect of the present invention is mainly manifested in: effectively avoid problem, the lifting reliability that cannot normally unblank when can not link insurance, unlatching when closing.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram of prerotation vane of self-lock.
Fig. 2 is the schematic diagram of portable plate.
Fig. 3 is the schematic diagram of the prerotation vane of another kind of self-lock.
Fig. 4 is the schematic diagram of motion stops.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
With reference to Fig. 1 ~ Fig. 4, a kind of prerotation vane of self-lock, described prerotation vane 1 has the lockhole 2 stretched out for the main lock core of self-lock, safe lock cylinder, described prerotation vane 1 also installs movable part, the collision bead of described movable part and described self-lock is just right, described movable part is connected with elastic telescopic mechanism, and during original state, the elastic force of elastic telescopic mechanism is greater than the stress value triggering described collision bead action.
Further, described movable part is portable plate 3, described portable plate 3 is curved, described portable plate 3 is positioned at the installing hole 4 of prerotation vane 1, and the cambered surface of described portable plate 3 exceeds described prerotation vane 1 place plane, described portable plate 3 is conflicted with torsion spring 5 one end, and the other end of described torsion spring 5 is arranged on bearing pin 10, and described bearing pin 10 is arranged on the bottom of described prerotation vane 1.
The bottom of described portable plate is installed in rotation on described bearing pin.This form of structure, is convenient to portable plate location.
Further again, described movable part is motion stops 6, in the installing hole of described prerotation vane 1, gathering sill 7 is installed, described motion stops 6 can telescopically be positioned at described gathering sill 7 up and down, piston rod 8 is installed in the bottom of described motion stops 6, and described piston rod 8 stretches out the through hole of the bottom of described gathering sill 7, pocketed springs 9 on described piston rod 8, setscrew nut 11 is installed in the lower end of described piston rod 8, and the external diameter of described setscrew nut 11 is larger than described through hole.
Certainly, described movable part also can be other forms, elastic telescopic mechanism except torsion spring, spring also can be other modes.
In the present embodiment, by arranging movable part and elastic telescopic mechanism, regardless of distant or close together between described doorframe and lockset, effectively collision bead can both be touched, and the situation effectively avoiding collision bead stuck, improve reliability.
