detailed description of the inventionbelow in conjunction with detailed description of the invention, the utility model is described in further detail:

As shown in Figure 1, Figure 2 or shown in Fig. 3, a kind of motor vehicle lock of the utility model, it is located at the chain wheel cover position on motor car engine, it comprises lock housing 1, lock collar 2 and lockset 3, lockset 3 and lock collar 2 are located in lock housing 1 respectively, before the minor sprocket 6 on the sheathed output shaft 5 of lock collar 2, lock collar 2 and output shaft 5 synchronous axial system, lock collar 2 is provided with plural lockhole 21; Described lockset 3 comprises the first support 31, second support 32, lock core 33, lock pin 34, push rod 35, triangle push pedal 36, drag hook 37 and latch 38, described first support 31 and the second support 32 are all fixed in lock housing 1, described first support 31 is provided with lock chamber 311, lock core 33 is slidably arranged in the lock chamber 311 of the first support 31, lock core 33 end passes the first support 31, inwall and the outer step surface arranged of lock core 33 that the first retracing spring 331, first retracing spring 331 two ends are limited in the first support 31 is respectively arranged with outside lock core 33; Triangle push pedal 36 is arranged with outside one end that lock core 33 extends the first support 31, triangle push pedal 36 outer wall is provided with chute 361, described chute 361 is arc with the cross section of lock core 34 axes normal, lock core 33 is installed with the push rod 35 wearing this chute 361, triangle push pedal 36 is also provided with along the downward-sloping skewed slot 362 of the pushing direction of lock core 33, in skewed slot 362, is provided with the drag hook 37 slided along skewed slot 362; Described lock pin 34 is slidably arranged in the inner chamber of the second support 32, and lock pin 34 one end can pass the second support 32 and stretch in the lockhole 21 of lock collar 2; The first pressure spring 321 is also provided with in the inner chamber of the second support 32; Second support 32 outer wall is provided with the second chute 322, and drag hook 37 one end is stretched into the second support 32 inner chamber through the second chute 322 and is fixedly connected with first pressure spring 321 one end, and first pressure spring 321 other end is resisted against lock pin 34 1 end face; Be arranged with the second retracing spring 341, second retracing spring 341 two ends outside described lock pin 34 and be limited in the outer step surface of setting of lock pin 34 and the inwall of the second support 32 inner chamber respectively; Described lock core 33 outer wall is provided with inserts 38 slots entered 332 for latch, and described slot 332 is arc with the cross section of lock core 33 axes normal; One end of corresponding first support 31 inwall of described latch 38 is provided with the second pressure spring 312.Be provided with position-limited trough 333 bottom described lock core 33, inwall corresponding position-limited trough 333 in described lock chamber 311 is provided with limiting stopper 313, and limiting stopper 313 is plugged in position-limited trough 333.By the cooperation of position-limited trough 333 and limiting stopper 313, when lockset is unblanked, lock core 33 outwards separating lock chamber 311 can be prevented.

Described lockhole 21 is two or more, and plural lockhole 21 is along the circumferential direction arranged in lock collar 2 equably.

Be provided with flameout switch 4 in described lock housing 1, flameout switch 4 is connected with ignition system; When described lockset is locked, lock pin 34 moves up and touches flameout switch 4, and ignition system disconnects.

Described lock core 33 comprises mandrel 334 and is set in the lock tube 335 outside mandrel 334, and mandrel 334 and lock tube 335 are rotationally connected.When the key hole of key insertion mandrel 334 is unblanked, by key 90-degree rotation, mandrel 334 also synchronous axial system, the first retracing spring 331 makes lock tube 225 be moved to the left, and in this process, lock tube 335 is not with mandrel 334 synchronous rotary.Lock tube 335 moves right when locking, to moving to left when unblanking.

As shown in Figure 1, when self-propelled vehicle is locked, firmly press down lock core 33 and make it move right, latch 38 inserts in the slot 332 of lock core 33 under the effect of the second pressure spring 312, locates lock core 33.Lock core 33 is turned right in moving process, lock core 33 promotes triangle push pedal 36 by push rod 35 and synchronously moves right, drag hook 37 is also synchronously moved up along skewed slot 362, the first pressure spring 321 that drag hook 36 other end connects upwards pressure to lock pin 34, promoting lock pin 34 inserts in the lockhole 21 of lock collar 2, lock pin 34 end contacts with the flameout switch 4 in lock housing 1, flameout switch 4 point of cutoff ignition system signal, thus driving engine cannot be started.Meanwhile, after lock pin 34 inserts the lockhole 21 of lock collar 2, lock collar 2 and engine output shaft 5 cannot be rotated, complete the process of locking.

Because lock housing 1 is provided with the sliding tray 11 of corresponding drag hook 37, drag hook 37 slides up or down along sliding tray 11.

When lock pin 34 does not insert the lockhole 21 of lock collar 2, described first Compress Spring 321 compresses and energy storage, first Compress Spring 321 continues to lock pin 34 1 thrust upwards, once after output shaft rotation, lock collar 2 is rotated thereupon, during lockhole 21 rotational alignment lock pin 34 in lock collar 2, lock pin 34 just can insert in lockhole 21, complete automatic locking process.

As shown in Figure 2, when unblanking, as long as key clockwise rotates 90 degree, lock core 33 slot 332 also synchronous axial system, because slot becomes smooth along with Angulation changes, latch 38 leaves the slot 332 on lock core 33, now, push rod 35 on lock core 33 rotates along the chute 361 in triangle push pedal 36, and triangle push pedal 36 keeps non rotating; Then lock core 33 is under the effect of the elastic-restoring force of the first retracing spring 331, and lock core 33 resets, thus drive triangle push pedal 36 toward moving left successively, drag hook 37 and lock pin 34 move down reset, lock pin 34 and flameout switch 4 disconnect, and depart from lock collar 2.

Described second retracing spring 341 has two kinds of functions, function one: reset response.Function two: safety effect, if when drag hook 37 is out of shape or disconnects, due to the existence of the second retracing spring 341, lock pin 34 can not upwards insert in the lockhole 21 of lock collar 2.
