The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises basic function part (seeing Fig. 4, Fig. 5 for details), this part mainly comprises locking bar 1, ratchet 5, unlocking rod 6, ratchet 5 rotates by axle and passes lock body 1, the other end connects dead bolt 3 (not shown), and unlocking rod 6 is positioned at the below of ratchet 5, and a vertical post 63 of unblanking is arranged at the middle part of unlocking rod 6, one end of unlocking rod 6 and lock body 1 are hinged, and the other end is connected on the lock body 1 by extension spring 62.Also comprise handle lever 7, shift fork 8, interior locking lever 9, fulcrum 71 in the middle of the handle lever 7 is rotatably connected on one side of described ratchet 5, the tail end 81 of one end and shift fork 8 is hinged, this end 81 also is connected with outer handle connecting rod B, the other end of this handle lever 7 is connected with interior handle connecting rod C by a hinge hook 10, at the middle part of handle lever 7 vertical end 72 is arranged, this end is connected with lock body 1 by extension spring 73; The fulcrum 91 of interior locking lever is rotatably connected on the connecting axle of described unlocking rod 6 one ends and lock body 1, an end of locking lever 9 is connected with interior locking connecting rod D in being somebody's turn to do, the other end is connected with locking head connecting rod E, vertical end 92 is arranged in the middle, at this end one driving lever 93 vertical with lock body 1 arranged, this driving lever 93 is positioned at the prong 82 of described shift fork 8.More stable for locking lever 9 residing two states that open and lock in making, can between one end and lock body 1, add a torsion spring 94.
Referring to Fig. 3, the hinge hook 10 that described and interior handle connecting rod is connected is the L type, and its middle part is hinged in the vertical end 11 of lock body, and one end and interior handle connecting rod C are hinged, and the other end leans against the downside of an end of described handle lever 7.
Referring to Fig. 4 and Fig. 5, this is the part of the utility model basic function, pass dead bolt axle 2 at lock body 1, both are for being rotationally connected, this end of 2 is a hook-type dead bolt 3, by the rotation of axle 2, dead bolt 3 expansibles or close, the snap close 4 that will be fixed on when closing on the car door frame is stuck in the recess 11 of lock body.What be connected axle 2 other ends is ratchet 5, and its outer rim has two ratchets, the ratchet 61 at corresponding therebetween adjacent unlocking rod 6 middle parts, and an end and the lock body 1 of unlocking rod 6 are hinged, and the other end has extension spring 62 to be connected on the lock body 1.The torsion that on dead bolt axle 2, also has torsion spring 21 to produce to a direction.When the ratchet 61 that makes unlocking rod 6 by transmission mechanism left ratchet 5, it rotated under the effect of torsion spring 21, and dead bolt 3 is opened; When at closing time, dead bolt 3 turns to fastening position under the percussion of snap close 4, makes it block snap close A, and the ratchet of ratchet 5 and 61 engagements of the ratchet on the unlocking rod 6 are blocked, and ratchet 5 can not be in the state of locking a door to back rotation.
After main purpose of the present utility model is exactly in car to lock a door with lockable mechanism, again can not be with inside and outside handle with car door opening, available key opens the door by tapered end.Its operating principle is as follows:
At first repeat process at the switch door described in the explanation of Fig. 4 and Fig. 5, promptly when the time from lock attitude unlatching door, the end that unlocking rod 6 connects extension spring 62 must be depressed (promptly opposite with the pulling force of extension spring 62 power), make ratchet 61 on the unlocking rod 6 leave the ratchet of ratchet 5, ratchet 5 rotates under the effect of torsion spring 21, makes dead bolt 3 get back to the state of (unlatching) of relieving.
Referring to Fig. 1, handle lever 7 two ends connect inside and outside handle respectively, they all can drive handle lever 7 and turn over certain angle clockwise around its fulcrum 71, and drive shift fork 8 downward straight lines simultaneously and move, because locking lever 9 is in lockup state (locking rod is depressed promptly) downwards in this moment, shift fork 8 ends drive the post 63 of unblanking that has left on the unlocking rod 6 at the driving lever on the interior locking lever 9 93, can not promote unlocking rod 6 actions so inside and outside handle drives moving of shift fork 8, and dead bolt 3 can not be opened.
Referring to 2, when interior locking connecting rod D is upwards pulled out (or the head that opens the lock with the key, also can play same function by locking head connecting rod E), locking lever 9 rotates around 91 pages of hour hands of its fulcrum in making, and shift fork 8 ends are pushed post 63 upsides of unblanking facing to unlocking rod 6 by the driving lever on it 93, move down shift fork 8 by inside and outside handle this moment again, just can promote unlocking rod 6 reverses downwards, make ratchet 61 on it leave the ratchet of ratchet 5, ratchet 5 rotates under the effect of torsion spring 21, drive dead bolt and become opening, car door just can be opened.
If car door is depressed (lock attitude) with interior locking connecting rod D opening mistiming, rotates under snap close A effect at dead bolt 3 at closing time, and in driving by ratchet 5 locking lever 9 to get back to heeling condition be opening, prevented to lock by mistake.
