The utility model content
The utility model is in order to overcome weak point of the prior art, and a kind of steering wheel can not use under the ruined situation of lock even provide, and theftproof performance is good, the automobile anti-theft lock that reliability is high.
The utility model is achieved through the following technical solutions:
A kind of automobile anti-theft lock is characterized in that, is fixedly connected with the square joint pin down that places in the shell on the vehicle steering drive link, and described joint pin down is with movable sleeve outward; Described movable sleeve lower end is provided with the lower limit back-up ring, be connected with following joint pin by alignment pin with the last joint pin that following joint pin matches, be provided with the upper limit back-up ring in last joint pin upper end, described upper limit back-up ring is connected with shell by pin, and last joint pin upper end is connected with steering wheel; Described movable sleeve is meshed with gear wheel; Gear wheel is provided with limiting tooth, be provided with reference column with the corresponding position of limiting tooth, gear wheel is provided with the driver blade coaxial with gear wheel, described driver blade is provided with the driving cog that cooperates with reference column, the power transmission shaft of gear wheel is connected with lock core shaft, and described gear wheel, driver blade, lock core are fixed in the enclosure.
Gear wheel is provided with locking hole, and described locking hole is provided with lock pin, and described lock pin is connected with the pressing lock locking mechanism.
Described upper limit back-up ring lower end is provided with upper limit bit slice, and the lower limit back-up ring is provided with the lower limit bit slice.
Described lock core is fixed on the shell by supporting spring.
The utlity model has following technique effect:
Automobile anti-theft lock of the present utility model has only the private key of use by the gear wheel transmission steering wheel drive link to be connected just with vehicle steering can make the steering wheel operate as normal, theftproof performance is good, the reliability height can avoid vehicle to lose the economic loss that causes to user vehicle.
Description of drawings
Fig. 1 is the sectional view of the utility model automobile anti-theft lock;
Fig. 2 is the running part schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
The schematic diagram of the utility model automobile anti-theft lock is fixedly connected with the square joint pin 5 down that places in the shell 10 as depicted in figs. 1 and 2 on vehicle steering drive link 8, be with movable sleeve 4 outside the joint pin 5 down.Described movable sleeve lower end is provided with lower limit back-up ring 7, be connected with following joint pin by alignment pin 3 with the last joint pin 9 that following joint pin matches, be provided with upper limit back-up ring 1 in last joint pin upper end, the upper limit back-up ring is connected with shell by pin, and last joint pin upper end is connected with steering wheel.Described movable sleeve 4 is meshed with gear wheel 11.Gear wheel 11 is provided with limiting tooth 17, be provided with reference column 16 with the corresponding position of limiting tooth, gear wheel is provided with the driver blade 12 coaxial with gear wheel, described driver blade is provided with the driving cog 15 that cooperates with reference column, the power transmission shaft 13 of gear wheel is connected with lock core shaft 20, and described gear wheel 11, driver blade 12, lock core 19 are fixed in the enclosure.Described upper limit back-up ring 1 lower end is provided with upper limit bit slice 2, and lower limit back-up ring 7 is provided with lower limit bit slice 6.Lock core is fixed on the shell by supporting spring 23.
To go up joint pin in the motor racing process in order making, to keep connection stability between joint pin, the movable sleeve down, gear wheel 11 is provided with locking hole 14, and locking hole is provided with lock pin 22, and described lock pin 22 is connected with pressing lock locking mechanism 21.Described pressing lock locking mechanism can adopt pressing lock locking mechanism commonly used on the furniture door.Make joint pin when gear wheel rotates, when keeping connecting between joint pin, the movable sleeve down, depress the pressing lock locking mechanism, lock pin enters locking hole, and gear wheel can not rotate.When needs lock car, depress the pressing lock locking mechanism, lock pin withdraws from from locking hole, rotates gear wheel and makes joint pin, breaks away between joint pin, the movable sleeve down.
Key 18 inserts in the key hole of lock core 19, key, lock core shaft 20 rotates, thereby the driver blade 12 that drives on the connected gear wheel power transmission shaft 13 rotates, the reference column 16 that driving cog 15 on the driver blade promotes on the gear wheel rotates gear wheel, and the movable sleeve 4 that meshes with gear wheel moves upward, and is connected with last joint pin, steering wheel is connected with the steering wheel drive link, and steering wheel can operate as normal.The backward rotation key, lock core shaft rotates, thereby the driver blade that drives on the connected gear wheel power transmission shaft rotates, the reference column that driving cog on the driver blade promotes on the gear wheel rotates gear wheel, move downward with the movable sleeve of gear wheel engagement, break away from last joint pin, steering wheel and truck drive shaft break away from, the steering wheel cisco unity malfunction.Therefore have only the key of use that steering wheel is connected with the steering wheel drive link, steering wheel ability operate as normal, theftproof performance is good, the reliability height.
Although relate to a kind of automobile anti-theft lock and carried out special description disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
