Description

The automobile burglar Fuel path lock

The utility model relates to a kind of automobile burglar Fuel path lock that locks the automobile oil circuit.

At present, the anti-joyride device of automobile is broadly divided into Door Lock, electric door lock and all kinds of antitheft special-purpose lock.Wherein Door Lock, the electric door lock person that is easy to the stolen car overcomes and loses antitheft effect, and antitheft special-purpose lock as bearing circle crutch are locked, and very inconvenient again in use, electronic anti-theft is latched in cost height, poor practicability, is difficult to shortcomings such as popularization.In recent years, the anti-joyride device that adopts mechanical valve or solenoid control oil circuit to close, but its complex structure more, parts are various, make, install time-consuming.

The purpose of this utility model be to provide a kind of simple in structure, volume is little, simple installation, with low cost, adopts automobile burglar Fuel path lock key operated and locking automobile oil circuit.

The purpose of this utility model is achieved by the following technical solution: the automobile burglar Fuel path lock, comprise key, lock core, lock body, and wherein, be provided with lock core, spool, asphalt channel in the lock body, lock body is outside equipped with seal cover cap; The mutual joining place of its lock core and spool respectively is provided with a shift fork; Retaining pin is stuck in the draw-in groove of lock core; The spline pin is stuck in the draw-in groove of spool.

In addition, the angle of inclination of shift fork is 45 °.

The utility model adopts key operated and locking automobile oil circuit, and when this Fuel path lock was destroyed under lock-out state, oil circuit was promptly destroyed, and automobile loses supply capability, can't travel, and plays the function that prevents that automobile is stolen.Have simple in structure, volume is little, easy to use, simple installation, with low cost, characteristics such as theftproof performance is reliable.

The utility model is described in further detail below in conjunction with drawings and Examples: consult Fig. 1, shown in Figure 2, the automobile burglar Fuel path lock, mainly constitute by lock core 2, lock body 4, retaining pin 5,8, seal ring 6,11, spool 9, spline pin 10, be provided with asphalt channel 12 in its lock body 4, the two ends tapped bore joins with automobile oil pipe respectively, constitutes automobile fuel feeding path.Also be provided with lock core 2, spool 9 in the lock body 4, lock core 2 and spool 9 one ends respectively are provided with one 45 ° shift fork 13,14 (extremely shown in Figure 6 as Fig. 3), are connected mutually, and lock core 2 is stirred 9 pairs of oil circuits of spool and formed switch valve; Retaining pin 5 and 8 is passed in the draw-in groove that lock body 4 is stuck in lock core 2, plays the effect that prevents that lock core from withdrawing from; Spline pin 10 passes in the draw-in groove that lock body 4 is stuck in spool 9, spool 9 is played the effect of spacing spline.Seal ring 6 is housed on the spool 9, and seal cover cap 7 is equipped with seal ring 11 and covers on lock body 4; Also be provided with nut 3 on the lock body 4, the utility model can be fixedly installed in automobile oil circuit institute through any convenience.

When key 1 inserts and during the dextrorotation three-sixth turn, lock core 2 is stirred spool 9 from lock core groove, spool 9 clockwise rotates 90 degree, and spacing spool 9 and the lock core 2 of preventing of spline pin is rotated further, and transfers to key, and oil circuit locking at this moment can not fuel feeding, plays the automobile burglar effect.Insert key again, when left-hand revolution 360 was spent, lock core was stirred spool, and spool rotates counterclockwise 90 degree, and spacing spool and the lock core of preventing of spline pin is rotated further, and also can extract key, and oil circuit is communicated with, and recovers fuel feeding, automobile normal running.If when the utility model was destroyed under lock-out state, oil circuit was promptly destroyed, automobile loses supply capability, can't travel, and still can play the function that prevents that automobile is stolen.
