The specific embodiment
As Fig. 1, Fig. 2, Fig. 4, shown in Figure 5, the lock core side of the comprising tongue assembly of the upside-down mounting safe-guard door lock that the utility model provides, tiltedly tongue assembly and cucurbit lock 1, the tongue assembly side of comprising, the side tongue 3 and the first band tooth connecting lever 2, side's tongue 3 is slidingly mounted on the lock housing and square tongue 3 is provided with the gathering sill 4 that diagonally distributes, gathering sill 4 from left to right, from up to down tilt, the first band tooth connecting lever 2 is provided with first column 5, second column 6, first gear 7 and the shifting block of stirring for the cucurbit lock 8, first column 5 is arranged in gathering sill 4, and first column, 5 drive side's tongues 3 are made stretching motion when the first band tooth connecting lever 2 rotates; Tiltedly the tongue assembly comprises oblique tongue 9, the shift fork 10 and the second band tooth connecting lever 12, the second band tooth connecting lever 12 and the socket of handle plug-in unit, door handle is plugged on the handle plug-in unit, can be called the utility model patent of anti-theft lock core with reference to the name of applying on the same day with this patent about inside and outside handle plug-in unit with the structural relation of the second band tooth connecting lever 12, the second band tooth connecting lever 12 is provided with second gear 13, second gear 13 and 7 engagements of first gear, shift fork 10 is rotationally connected by rotating shaft with lock housing, shift fork 10 right-hand members are in block piece below, oblique tongue bottom (so-called below is that Fig. 1 is that the pass, position is an example), and common shifting fork 10 contacts with the block piece bottom.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, be arranged with transmission circle 11 on the second band tooth connecting lever 12 on the basis of the foregoing description, the second band tooth connecting lever 12 can relatively rotate with transmission circle 11, transmission circle 11 is provided with kink 14 and projection 15, projection 15 contacts with shift fork 10 left ends, the first band tooth connecting lever 2 and the second band tooth connecting lever, 12 tops are provided with guide strip 16, guide strip 16 is provided with swinging chute 17 and through hole 18, swinging chute 17 is that bending distributes and the turning is curved, kink 14 pass that through hole 18, the second columns 6 are arranged in swinging chute 17 and when the first band tooth connecting lever 2 rotates second column 6 promote guide strips 16 left-hand end and move up and down.
In the present embodiment, door handle is in the panel of lock below, after panel of lock is installed, still have redundant space after Fingerprint Identification Unit or cipher input or brushing card device are installed, the area that just can reduce panel of lock when making panel of lock makes panel of lock that door handle and Fingerprint Identification Unit or cipher input or brushing card device enough are installed and gets final product.
The lock core of describing the upside-down mounting safe-guard door lock that the utility model provides below in detail is by cucurbit lock release and closedown mode:
First, side's tongue release can only pass through the electronic lock release, thereby the cucurbit lock 1 that perhaps turns clockwise is stirred shifting block 8 and driven first and be with tooth connecting lever 2 to rotate counterclockwise, impel first column 5 on the first band tooth connecting lever 2 upwards to oppress the upper side wall of gathering sill 4, contract in 3 releases of the side's of impelling tongue.
Second, tiltedly tongue release, when cucurbit lock first lap is swung clockwise second column 6 by move for 17 li at swinging chute make guide strip 16 to bottom offset (reason be second column 6 along swinging chute 17 in a left side moves right process, along the tendency of the swinging chute of bending state to lower compression guide strip 16, both can not bump above guide strip 16 was in cucurbit lock swinging track before this), this moment continue to clockwise rotate cucurbit lock 1 one the circle after, cucurbit lock 1 promotes guide strip 16 and moves right, because kink 14 passes through hole 18 guide strip 16 and transmission circle 11 is in transmission connection, transmission circle 11 can move right and does and clockwise rotate along with guide strip 16, projection 15 on the transmission circle 11 promotes shift fork 10 left ends rotates shift fork 10, shift fork 10 right-hand member counter-clockwise swings, thus and then promote oblique tongue 9 bottoms and oblique tongue 9 is contracted inward reach the purpose of release.
Closedown mode of the present utility model only need rotate counterclockwise the cucurbit lock and get final product, its step is opposite with the release mode, general only need to rotate a circle can the side's of protrusion tongue 3 and tiltedly tongue 9 make it be in locking state, certainly the cucurbit lock need to rotate several circles fully release can carry out personalization adjustment as required, can be that a circle release also can be two to enclose release side's tongue 3 and oblique tongue 9 stage by stage.
