The utility model content
In order to overcome the problem of existing electronic lock theftproof performance difference, the utility model provides a kind of fingerprint electronic safety lock, and this fingerprint electronic safety lock has increased by two semi-circular dead bolts on the basis of existing technology, has improved its theftproof performance effectively.Have characteristics simple in structure and that theftproof performance is good.
The technical scheme of the utility model is: a kind of fingerprint electronic safety lock comprises electronic-controlled installation and lockset; Mechanical lock mainly by lock body, lock main dead bolt, tiltedly dead bolt, indoorly lock dead bolt, dead bolt driving mechanism, go up locking bar and down locking bar forms, the dead bolt driving mechanism comprises master gear, oblique dead bolt fork and pivoted arm, pivoted arm has half gear that is meshed with master gear; Pivoted arm through bearing pin with lock main dead bolt, go up locking bar and down locking bar be connected; Locking bar was provided with skewed slot in the opposite direction under last locking bar reached, and bearing pin is positioned at skewed slot, and the both sides up and down of lock body are hinged with semi-circular dead bolt respectively; The sidewall of lock body is provided with the through hole that semi-circular dead bolt passes and penetrates; The center fixation of semi-circular dead bolt has gear, last locking bar and down be equipped with tooth bar on the locking bar, and tooth bar is meshed with gear on the corresponding semi-circular dead bolt.
Be hinged with torsion spring on the described lock body, the other end of torsion spring and the end of semi-circular dead bolt are hinged.
The inwall of described semi-circular dead bolt is fixed with two spokes, and gear is fixed on the infall of two spokes.
Described cross section of locking main dead bolt and semi-circular dead bolt is rectangle or circle.
It is described that to lock main dead bolt be single overall structure, two branched structures, three branched structures and a plurality of branched structure.
The utlity model has following beneficial effect: owing to take such scheme; Two semi-circular dead bolts in lock body, have been increased; Two semi-circular dead bolts reach locking bar interlock down with last locking bar respectively; Realize locking and unblanking, improved the theftproof performance of lockset, have characteristics simple in structure and that theftproof performance is good.
Description of drawings
Accompanying drawing 1 is the structural representation of the lock-out state of the utility model.
Accompanying drawing 2 is structural representations of the unlocking condition of the utility model.
1-lock body among the figure, 2-locks main dead bolt, the oblique dead bolt of 3-, the indoor dead bolt of locking of 4-, 5-dead bolt driving mechanism; The 51-master gear, the oblique dead bolt fork of 52-, 53-pivoted arm, 54-half gear, 55-bearing pin; The last locking bar of 6-, locking bar under the 7-, 8-skewed slot, the semi-circular dead bolt of 9-, 91-spoke; The 10-through hole, 11-gear, 12-tooth bar, 13-torsion spring.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Combine shown in Figure 2 by Fig. 1; A kind of fingerprint electronic safety lock comprises electronic-controlled installation and mechanical lock; Mechanical lock mainly by lock body 1, lock main dead bolt 2, tiltedly dead bolt 3, indoorly lock dead bolt 4, dead bolt driving mechanism 5, go up locking bar 6 and down locking bar 7 forms, dead bolt driving mechanism 5 comprises master gear 51, oblique dead bolt fork 52 and pivoted arm 53, pivoted arm 53 has half gear 54 that is meshed with master gear 51; Pivoted arm 53 through bearing pin 55 with lock main dead bolt 2, go up locking bar 6 and down locking bar 7 be connected; Locking bar 7 was provided with skewed slot in the opposite direction 8 under last locking bar 6 reached, and bearing pin 55 is positioned at skewed slot 8, and the both sides up and down of lock body 1 are hinged with semi-circular dead bolt 9 respectively; The sidewall of lock body 1 is provided with the through hole 10 that semi-circular dead bolt 9 passes and penetrates; The center fixation of semi-circular dead bolt 9 has gear 11, last locking bar 6 and be equipped with tooth bar 12 on the locking bar 7 down, and tooth bar 12 is meshed with gear 11 on the corresponding semi-circular dead bolt 9.Owing to take technique scheme; In lock body 1, increased by 9, two semi-circular dead bolts 9 of two semi-circular dead bolts and reached locking bar 7 interlocks down with last locking bar 6 respectively, realized locking and unblanking; Improve the theftproof performance of lockset, had characteristics simple in structure and that theftproof performance is good.
Be hinged with torsion spring 13 on the described lock body 1, the end of the other end of torsion spring 13 and semi-circular dead bolt 9 is hinged.When locking, last locking bar 6 and locking bar 7 direction motion up and down respectively down drive semi-circular dead bolt 9 and rotate; Also torsion spring 13 is compressed torsion spring 13 along with rotating simultaneously; Semi-circular dead bolt 9 is when the position, and the energy of torsion spring 13 savings discharges, and promotes the locking that puts in place fast of semi-circular dead bolt 9; Process with when locking when unblanking is opposite.Can make the operator that feel is preferably arranged like this.
