The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
As Figure 1-3, present embodiment provides a kind of rack and pinion drive mechanism of electronic lock, and it comprises panel and lock body drain pan 1, square tongue assembly 2, tiltedly tongue assembly 3, tiltedly tongue lever 4, square core 5 and square core gear 6, tooth bar 7, idler gear 8, turn-button gear 9.
The square core gear that wherein is positioned at the tooth bar downside is positioned at the idler gear of tooth bar upside and the turn-button gears engaged of drive side's tongue motion by the Fang Xin connection drive that can rotate and can open oblique tongue with Door handle.
Side's core 5 is cast form, and on the circular hole of the cylinder boss lock body drain pan that is hinged on oblique tongue assembly 3 belows and lock cover, center square hole 5a inserts rotations for handle square rod 10 up and down.The intermediate cylindrical member of described Fang Xin is provided with monodentate spline 5b, is used to the rotation of the side's of drive core gear 6.The clockwise rotating of side's core 5 makes oblique tongue lever 4 drive oblique tongue assembly 3 by cam angle 5c and withdraws in lock body, realized that oblique tongue, square tongue withdraw together and open the door.
Side's core gear 6 is established arc groove 6a for drawing on the center hole, be used to the rotation torsion of the side of transmission core monodentate spline 5b, outside profile of tooth 6b and tooth bar downside profile of tooth 7a engagement.
Idler gear 8 is cast form, and bottom is established profile of tooth 8a, and profile of tooth 8b is established on the upper strata, and center hole is enclosed within on the gear spindle 8c of lock body drain pan, bottom profile of tooth 8a and tooth bar profile of tooth 7b engagement; Profile of tooth 8b and turn-button gear 9a engagement are established in the upper strata.
Turn-button gear 9 is cast form, and on the circular hole of the lock body drain pan of the cylinder boss side of being hinged on tongue assembly 2 tops and lock cover, the center oblong aperture is inserted for turn-button and rotated, and establishes crank 9b on the cylinder on profile of tooth upper strata up and down, and the crank front end is established T shape rivet 9c.Torsion is transmitted in profile of tooth 9a and idler gear 8b engagement, and the crank 9b side of drive tongue moves horizontally, and on the T shape rivet 9c torsion spring is housed.
The transmission principle of locking a door with the handle square rod: as Fig. 1, shown in 3, carry when rotating on doing among the square hole 5a of handle square rod 10 insertion side's cores 5, the monodentate spline 5b side of drive core gear 6a rotates counterclockwise and by profile of tooth 6a, the engagement of 7b moves up tooth bar 7, the profile of tooth 8a engagement of tooth bar epimere profile of tooth 7b and idler gear is rotated the center tooth crop rotation inverse time, the profile of tooth 8b of idler gear and turn-button gear 9a engagement, turn-button gear 9 is clockwise rotated, the drive side's tongue that clockwise rotates of crank 9b is made level and is stretched out outside lock panel, thereby makes door lock be in locking states as Fig. 2.
The transmission principle that opens the door with the handle square rod: shown in Fig. 2,3, when door lock place and locking states, press down among the square hole 5a of handle square rod 10 insertion side's cores 5 when rotating, its drive path is: the monodentate spline 5b side of drive core gear 6 clockwise rotates, tooth bar 7 moves down, and center tooth crop rotation up time is rotated, and turn-button gear 9 rotates counterclockwise, the drive side's tongue that rotates counterclockwise of crank 9b is made level and is resetted in lock panel, thereby the side's of making gyrus lingulais is to released state.Meanwhile, the clockwise rotating of square core 5 makes oblique tongue lever 4 drive oblique tongue assembly 3 by cam angle 5c and withdraws in lock body, realized that oblique tongue, square tongue withdraw together and open the door.
The operating principle of the rack and pinion drive mechanism of the utility model electronics mortise door lock is:
The handle square rod of an electronic lock side is outdoors controlled by electric clutch, and electric clutch just can be in engagement state when receiving correct electric signal.
Handle is opened oblique tongue process outdoors: handle pressed down rotation when electric clutch was in engagement state, by handle square rod, Fang Xin, the oblique mechanism driving of tongue lever, oblique tongue assembly was withdrawn in the lock panel and open the door (this moment side's core gear does not rotate).
Turn-button locking and unlatching side's tongue process in the door: as long as the interior turn-button of rotary door can make the crank side of the drive tongue of turn-button gear move horizontally, reach the purpose of locking a door and opening the door in any case.
Handle locking side tongue process outdoors: carry handle on when electric clutch is in engagement state, by the mechanism driving of handle square rod, Fang Xin, square core gear, tooth bar, idler gear and turn-button gear, square tongue assembly is transferred to lock panel and lock a door (electric clutch just is in disengaged position under the locking states).
Handle is opened oblique tongue and square tongue process outdoors: when door lock locking and electric clutch are in engagement state, rotate Door handle, by the mechanism driving of handle square rod, Fang Xin, square core gear, tooth bar, idler gear, turn-button gear, square tongue assembly; By the mechanism driving of handle square rod, Fang Xin, oblique tongue lever and oblique tongue assembly, make oblique tongue and square tongue withdraw together and open the door simultaneously.
Handle is operated oblique tongue and square tongue process in the door: handle in the door that the square rod other end is connected, not controlled by electric clutch, therefore under any circumstance need only propose rotation just can be with square tongue locking; Press down to rotate and just oblique tongue and square tongue can be opened together, its transmission principle is identical with the drive path of handle outdoors.
The above is a preferred implementation of the present utility model; certainly can not limit the interest field of the utility model with this; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement and change, these improvement and change also are considered as protection domain of the present utility model.
