Abstract
The utility model relates to an oblique lock-tongue direction-changing mechanism of a mechanical lock, which is composed of a diamond-shaped oblique lock tongue, a pressure spring, a direction-changing transmission mechanism and a direction-changing force application member, wherein in the direction-changing transmission mechanism, at least three linkage rods form a linkage relationship; each of the linkage rods is respectively provided with a rotary fulcrum A, a rotary fulcrum B and a rotary fulcrum C which are connected with a lock body; a torsion spring is installed on one of the rotary fulcrums; the terminal end of a first linkage rod is connected with the starting end of a second linkage rod through a transmission pin a, and the terminal end of the second linkage rod is connected with the starting end of a third linkage rod through a transmission pin b to form to transmission points; the starting end of the first linkage rod is connected with the direction-changing force application member; the terminal end of the third linkage rod is correspondingly matched with a clamping groove on the side face of the oblique lock tongue. When the starting end of the first linkage rod is stressed, the terminal end of the third linkage rod is clamped in the clamping groove to restrict the oblique lock tongue to rotate; inversely, when the terminal end of the third linkage rod is out of the clamping groove, the oblique lock tongue can freely change directions in the process of locking and unlocking. Therefore, the convenience of locking and unlocking a lock is improved, the service life of the lock is prolonged and the heat preservation performance and the sound insulation performance of a door leaf are improved.
Description
Technical field
The utility model belongs to lockset manufacturing technology field, is specifically related to a kind of oblique dead bolt commutating structure of mechanical lock.
Background technology
Be used at present that lockset on the door is of a great variety, performance is different on often, but their oblique dead bolt is all not capable of reversing, wants frequent in the use and rubs with doorframe, causes dead bolt and doorframe to wear and tear, and has shortened the application life of lockset.Moreover, influence fitting tightly of door leaf and doorframe, the insulation and the sound insulation value of door are weakened.
Summary of the invention
The utility model does not have commutation function at the oblique dead bolt that present mechanical lock exists, disclose a kind of oblique dead bolt commutating structure of mechanical lock, make its oblique dead bolt capable of reversing in the switching process, improve the convenience of switch lock, prolong the application life of lockset, improve insulation, the sound insulation value of door leaf.
Technical solution of the present utility model is as follows:
The utility model just partly improves at the oblique dead bolt of mechanical lock, the lockset that it can constitute a complete function with other parts such as main dead bolt, the safety tongue etc. of existing machinery lock.
This oblique dead bolt commutating structure is made up of oblique dead bolt, a stage clip and a cover commutation transmission mechanism and a commutation force application part of a rhombus.
Lock body is stretched out in described oblique dead bolt outer end, and the inner is equipped with stage clip, and the stage clip end is fixed on the appropriate location of lock body, and when at closing time, tiltedly dead bolt reaches flexible purpose by external force effect compression press spring.In order to commutate back location, tiltedly dead bolt has draw-in groove in side up and down.
Described commutation drive mechanism constitutes interaction relation by at least three gangbar, and they have rotating fulcrum A, B, the C that is connected with lock body respectively, makes them can rotate around it fulcrum under external force and rotates.On the rotating fulcrum torsion spring is installed therein, is produced corresponding reset force to rotate the back to it.The top of the end of first gangbar and second gangbar, the top of the end of second gangbar and the 3rd gangbar is coupled together by trundle a and b respectively, form two drive station, the top of first gangbar connects the commutation force application part, accept the commutation power that the outside applies, the draw-in groove corresponding matching of the end of the 3rd gangbar and oblique dead bolt side, like this in that the top of first gangbar is not stressed when being F1=0, the end of the 3rd gangbar is stuck in the draw-in groove of a side of oblique dead bolt, oblique dead bolt can not be rotated, otherwise, then withdraw from draw-in groove, tiltedly dead bolt is free to rotate, realizes commutation.
Described commutation force application part and door handle, knob or/and the drive link that drives by this mechanical lock core is connected and drives the commutation power that acceptance is applied by them.
Further, in order to make oblique dead bolt after commutation, reach more stable location, also can all leave relative draw-in groove in the two sides up and down of oblique dead bolt, design second gangbar simultaneously and also have the 3rd end, the draw-in groove corresponding matching of the 3rd end and oblique dead bolt another side, like this at the top of first gangbar when not stressed, the 3rd end of second gangbar is stuck in the another side draw-in groove of oblique dead bolt, block oblique dead bolt with the 3rd gangbar, in like manner, under the situation that is applied in commutation power, two gangbar then withdraw from draw-in groove, tiltedly dead bolt is free to rotate, realizes commutation.
Below just tiltedly the commutation and the telescopic process of dead bolt do an explanation:
1, arrive from handle when the top of first gangbar is stressed, knob is or/and during the power of the drive link that is driven by this mechanical lock core, be F1＞0: under the effect of F1 power, first gangbar activity supporting point B that rotates turns an angle, the torsion spring that is installed in this moment on the rotating fulcrum produces certain torsion, drive station a rotates also power transmission in second gangbar thereupon, second gangbar turns an angle around fulcrum C, drive station b rotates also power transmission in the 3rd gangbar thereupon, therefore the second and the 3rd gangbar is rotated respectively, force direction points to the lock body wall that closes on, second and three gangbar front ends withdraw from the draw-in groove of oblique dead bolt both sides respectively, and at this moment, tiltedly dead bolt just can freely commutate.
2, when the top of first gangbar remove stressed after, promptly during F1=0, under the reducing power effect of torsion spring, second and three gangbar front ends snap in respectively in the draw-in groove of oblique dead bolt both sides, at this moment, tiltedly dead bolt can not commutate, and can only do common stretching motion.
Advantage of the present utility model is as follows:
1, when mechanical lock under the state that master latch is opened, outdoor by swing handle or knob, force in the commutation transmission mechanism in this lock, unclamp oblique dead bolt, make oblique dead bolt commutation at the interaction force minimum between oblique dead bolt and the doorframe that leans in a flash that opens the door, it is just extremely convenient to open the door like this, the trouble of having removed the key operated oblique dead bolt of outdoor use from.
2, because of tiltedly dead bolt is capable of reversing, reduced the friction with doorframe, can prolong the application life of lockset.
3, door leaf direction of oblique dead bolt when closing changes thereupon, makes the applying of door leaf and doorframe tightr, thereby insulation, the sound insulation value of door are improved environmental protection more.
This commutating structure can be used in the theftproof lock, also can be used for doing the passageway lock.
