The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

As shown in Figure 1.

A kind of chain vehicle theftproof lock, comprise base plate 1, have the chain 5 that lock housing 3, lock core 4, the manganese steel of chassis 2, the alarm bell shape of arch safe edge 20 are made, base plate 1 is provided with the fixing hole that is used to be fixed, chassis 2 links to each other with base plate 1, lock core 4 is installed on the lock housing 4, be processed with the keyhole of plug-in mounting key on the lock housing 4, lock core 4 is connected with the lock core shift lever 17 of this theftproof lock that has of switch, and lock core shift lever 17 drives driving lever 15 around fulcrum (O under the drive of key ₃) rotate, 2 center position is provided with the rectangular guide pillar in a cross section 6 and (also can be square on the chassis, triangle or other polygonized structure), around guide pillar 6, be provided with limited post 7 and (can be column structure, its upper end is provided with a limited block) and some chain posts 8 (every chain post 8 more than 4 or 4 can be set to theftproof lock), the size of chain post 8 should be less than the size of the centre bore of chain 5, so that chain 5 can overlap on the cochain post 8, be provided with the chain jack 11 that matches with chain post 8 quantity in the corresponding position of lock housing 3, chain 5 is actively socketed on (as shown in fig. 1) on the chain post 8, chain 5 can adopt manganese steel loop chain as shown in Figure 1 during concrete enforcement, also can adopt the rope chain of bracelet; Be provided with in the lock housing 3,

lower plate

9,10, between the two by a connecting rod and junction plate 12 location, wherein lower plate 10 is fixedly linked with the inwall of lock housing 3 and (train wheel bridge 9 and the inwall of lock housing 3 is fixedly linked, or the two all is fixedly linked with the inwall of lock housing 3), and be sleeved on the limited post 7, the upper end of limited post 7 is provided with one and prevents that lower plate 10 breaks away from the limited block 21 (also can be other similar devices) of limited post 7, the height of limited post 7 should be greater than the height of chain post 8, so that can drive chain 5 when lock housing 3 is upspring from shape chain post 8, be convenient to chain 5 is taken out from jack 11, realize the purpose of unblanking.Equal movable set also is set with back-moving spring 13 on upper and lower two laminated

planks

9,10 on the guide pillar 6 that is positioned at lower plate 10 bottoms on guide pillar 6; Between upper and

lower clamping plate

9,10 jam plate 14 is installed, jam plate 14 is provided with the jack that matches with guide pillar 6 and is inserted on the guide pillar 6, and the end hinge of jam plate 14 is contained in (O on the described junction plate 12 ₁The point place), the other end presses on the galianconism end of driving lever 15, at jam plate 14 close pin joint (O ₁) an end on little spring 16 is installed, one end of little spring 16 is fixed on the soffit of train wheel bridge 9, the other end and jam plate 14 offset, little spring 16 produces a pressure, make jam plate 14 have a moment of rotating all the time around pin joint, driving lever 15 L-shaped structures, its long-armed then hinge with junction galianconism is contained in (O on the lower plate 10 ₃The point place), the long arm end of driving lever 15 then contacts with lock core shift lever 17, and lock core shift lever 17 is installed on the lock core 4, and lock core 4 is driven around O by key ₂Point rotates.

For the ease of the installing and locating of chain 5, can be when specifically implementing at the soffit and the chain post 8 relative locator cards 18 that are provided with the insertion end location that makes chain 5 with regard to the position of lower plate 10.

Operating principle of the present utility model is:

As shown in Figure 1, jam plate 14 is subjected to a downward pressure under the effect of little spring 16, makes jam plate 14 produce one with pin joint O ₁Counterclockwise moment for the center, the two relative limits of the rectangular opening on the jam plate 14 then are pressed on two limits of the guide pillar 6 that is all rectangle, guide pillar 6 is then produced constraint reaction by the pressure place, this constraint reaction can be decomposed into horizontal component and vertical stress component and produce corresponding constraint reaction idol square, produce frictional force between the horizontal component of constraint reaction and the guide pillar 6, when this frictional force during greater than the elastic force of back-moving spring 13, entire mechanism is in locking state, when the frictional force of contact position during less than the elastic force of back-moving spring 13, lock housing 3 will be to upwards sliding and upspring (as shown in Figure 2) along guide pillar 6, when elastic force sum that downward active force makes progress greater than the frictional force and the back-moving spring 13 of contact position, lock housing will be to lower slider, the principle that why downwards light pressure that Here it is can make lock housing 3 move down, as shown in Figure 3.

When lock-out state, utilize key rotation lock core 4, lock core 4 drives coupled lock core shift lever 17 around center O ₂Rotate, lock core shift lever 17 is depressed the long arm end of driving lever 15 to counter clockwise direction, and this long arm end drive galianconism end is around pin joint O ₃Rotate, the galianconism end then upwards lifts jam plate 14, reduce or eliminated frictional force between jam plate 14 and the guide pillar 6, thereby lock housing 3 is moved up under the effect of back-moving spring 13, lock housing 3 is separated with chassis 2, as shown in Figure 2, can pull out lock housing 3 this moment with chain 5 from locator card 18, realizes the purpose of unblanking.When backward rotation lock core 4 and after taking off, the long arm end of driving lever 15 loses constraint, because jam plate 14 is subjected to the effect of little spring 16, produces a downward moment of torsion, the galianconism end of driving lever 15 under the compressing of jam plate 14 promptly around pin joint O ₃Rotate counterclockwise, driving lever 15 is in the lock state for the treatment of shown in Figure 3.

It is all same as the prior art that the utility model does not relate to part.
