Description

A kind of combined type anti-theft vehicle lock

Affiliated field

The utility model relates to a kind of lock, relate to or rather be used for a kind of two taking turns, the theftproof lock of three-wheeled vehicle, divide by International Patent Classification (IPC) (IPC) and to belong to operation Department of Transportation, communications and transportation branch.

Background technology

Along with the raising gradually of living standard, people's walking-replacing tool is except bicycle, and the motorcycle of various novelties, power assist vehicle etc. also enter ordinary citizen house, brings great convenience for people's trip.Simultaneously, because the stolen phenomenon of vehicle takes place repeatedly, also brought the worry that can't state, particularly bicycle to people, car body is less, and weight is lighter, especially robber's preferred object.The theftproof lock of existing vehicle is various in style, form each one, adopt outer exposure formula more, single lock point, stolen easily, theftproof performance is relatively poor.

Summary of the invention

The utility model provides the anti-theft vehicle lock of a kind of combined type, enclosed type, Multiple locking point at the deficiencies in the prior art.

The technical solution of the utility model is such: it comprises shell, steel wire, band-type brake pot etc., and lock body and fixing iron are set in the enclosure, the band-type brake pot, fixedly all has locked groove on the iron; Two row's pellets shot from a slingshot are set on lock body, between lock core in lock body and the steel mortise lock head moving component are set, steel mortise lock head is moved up and down; One end of steel wire is fixed on fixedly on the iron, and the other end connects the steel wire tapered end, has the R breach on steel mortise lock head and steel wire tapered end.

The described moving component that is provided with is fixed gear on lock core, and steel mortise lock head connects tooth bar by alignment pin.

Also fixedly electric conductor and isolator on the described lock core.

The beneficial effects of the utility model:

1, has two lock points, overcome the disadvantage of monolock point.One be in the lock body steel mortise lock head along with the motion of gear, tooth bar drop to the band-type brake pot, fixedly in the locked groove of iron, locked wheel has better hidden anti-theft feature; Another is that the steel wire tapered end of steel wire can be inserted in the lock body and joins with steel mortise lock head, forms blocking.

2, applied range both can be used for bicycle, tricycle, also can be used for motorcycle, power assist vehicle etc.If on lock core, connect electric conductor and isolator, can increase a lock point again, promptly for power assist vehicle, motorcycle, during power connection, steel mortise lock head just can leave band-type brake pot, the fixing locked groove of iron; When the power supply weak point was opened, steel mortise lock head just fell into band-type brake pot, the fixing locked groove of iron.

3, the utility model adopts closed assembling, is provided with row's pellet shot from a slingshot more, and lock point is survivable, and theftproof performance is good, and materials economize, and processing, operation easily, installs, and is easy to use.

The specific embodiment

As shown in Figure 1, lock body 2 and band-type brake pot 9, fixing iron 10 are arranged in shell 1, band-type brake pot 9, fixedly all have locked groove on the iron 10.As shown in Figure 2, fixedly the projection of iron 10 directly is stuck on the axletree 12 in the car beam groove 13, and is fastening with nut, plays the effect of fixed housing 1.

First row's pellet shot from a slingshot 15, second row's pellet shot from a slingshot 16 are set on lock body 2, in lock body 2, be provided with lock core 3, steel mortise lock head 6, moving component is set between the two, shown in accompanying drawing 1,2, gear 4 is installed on lock core, steel mortise lock head 6 connects tooth bar 5 by alignment pin 7, relies on the motion of gear 4, tooth bar 5 to drive moving up and down of steel mortise lock head 6.Above-mentioned moving component is also mentioned wheel and spring, or cam, spring and steel are slotting, or the combination of shift fork and spring.

One end of steel wire 11 adopts methods such as welding, riveted joint to be fixed on fixedly on the iron 10, and other end connection has the steel wire tapered end 8 of bayonet socket, all has the R breach on steel mortise lock head 6 and steel wire tapered end 8.

Steel wire tapered end 8 is in the outside of shell 1, removable when not locking, when needing locking, insert in the lock body 2, key is inserted lock core 3 rotate up 90 °, driven gear 4, tooth bar 5 rotates, and steel mortise lock head 6 is moved down, and falls into band-type brake pot 9, fixedly in the locked groove on the iron 10, can pin wheel, steel wire tapered end 8 does not overlap with the R breach of steel mortise lock head 6 simultaneously, and promptly the R breach of steel wire tapered end 8 just in time inserts the disc of steel mortise lock head 6, thereby forms locking state.At this moment, in second row's pellet shot from a slingshot, the 16 incision lock cores 3, first row's pellet shot from a slingshot 15 then contacts with the disc of lock core 3.

Among Fig. 2, the position after the dotted line in the lock body 2 is represented to move on the steel mortise lock head 6.In the time of need unblanking, key is inserted lock core 3 be rotated down 90 °, driven gear 4, tooth bar 5 rotates, and makes on the steel mortise lock head 6 and moves, and leaves band-type brake pot 9, the fixing locked groove on the iron 10.Simultaneously, the R breach on steel mortise lock head 6 and the steel wire tapered end 8 overlaps, and steel wire tapered end 8 can be extracted, and is hung on the Spring Card that is located at the car body correct position.At this moment, 16 discs with lock core 3 of second row's pellet shot from a slingshot contact.

As shown in Figure 2, on lock core 3, also can connect electric conductor and isolator 14, can increase a lock point like this, promptly for power assist vehicle, motorcycle, power supply disconnects during parking, be equivalent to key and insert lock core 3 and rotate up 90 °, make that gear 4 drives tooth bars 5, steel mortise lock head 6 moves down, fall into band-type brake pot 9, fixedly in the locked groove on the iron 10.
