Description

The anti-theft automotive fuel lid

Technical field

The present invention relates to a kind of anti-theft automotive fuel lid.

Background technology

Being connected of fuel filler pipe mainly is that buckle-type connects on existing vehicle fuel tank cap and the fuel tank, and the shortcoming that this connection mode exists is that theftproof performance is not good.For improving the theftproof performance of fuel tank, the mode that adopts usually is to connect the hasp that cooperatively interacts on fuel lid and fuel filler pipe respectively at present, and is aided with lockset with snap lock.But the hasp in this latch-up structure is in the open, and is easier to destroy.

Summary of the invention

The object of the present invention is to provide a kind of anti-theft automotive fuel lid, this fuel lid can cooperate with the inside of fuel filler pipe realizes locking.

For achieving the above object, the present invention adopts following scheme: the anti-theft automotive fuel lid, the enclosing cover internal fixation has inner cap, the roof of inner cap is outstanding to the uncovered direction of enclosing cover, has cavity between inner cap and enclosing cover, the middle part of lid top wall is penetrated with a permanent seat outside, one lock core passes permanent seat and lower end and stretches in the cavity between enclosing cover and inner cap, the top of lock core has an outstanding lock nose, lock has through hole on the nose, and the outside of lid roof is hinged with a locking plate, has on the locking plate and locks the groove that nose cooperates, the chute that has on the dead bolt in the pin that the lower end of lock core has and the cavity cooperates, and inner cap is stretched out in the front portion of dead bolt.

By such scheme as seen, at the inner block that cooperates with dead bolt that is provided with of fuel filler pipe, with vehicle fuel tank cap provided by the invention and fuel filler pipe screw be connected after, rotational lock core stretches out dead bolt, cooperate with block by dead bolt, can guarantee that this fuel lid can not be removed again, simultaneously locking plate is enclosed within on the lock nose, and with lockset both are locked, can finish the locking of fuel lid.

The present invention is simple and reasonable for structure, and it locks convenient, and safety is better.

cover

1,1 of inner cap 6 and enclosing cover have cavity, being penetrated with a permanent seat 4, one lock cores 5 at the middle part of enclosing cover 1 roof passes in the cavity that permanent seat 4 and lower end stretch to 6 of enclosing cover 1 and inner caps.The top of lock core 5 has an outstanding lock nose 5a, have through hole 5b on the lock nose 5a, the outside of enclosing cover 1 roof is hinged with a locking plate 3 that cooperates with lock nose 5a, and locking plate 3 and the pedestal 2 that is fixed on enclosing cover 1 roof are hinged, has on the locking plate 3 and locks the groove 3a that nose 5a cooperates.

Referring to Fig. 1, Fig. 2, Fig. 3

The chute 8a that has on the dead bolt 8 in the pin 5c that the lower end of lock core 5 has and the cavity cooperates, and inner cap 6 is stretched out in the front portion of dead bolt 8.Rotational lock core 5 by cooperating of pin 5c and chute 8a, can make dead bolt 8 stretch out or withdraws.

Referring to Fig. 2, Fig. 3

The bottom of inner cap 6 inboards is provided with a spring washer 7, is fixed with a plate spring 9 on the roof inboard that inner cap 6 is given prominence to, and the edge of plate spring 9 has a pair of positioned opposite and the outstanding claw 9a of being.

In addition,, tank filler tube is made conformability improve, make to have block and the fin that cooperates with dead bolt and claw respectively in the fuel filler pipe, this automotive oil tank failure-free is connected with fuel filler pipe and realizes locking at anti-theft automotive fuel tank provided by the invention.
