Description

A kind of high sealed lock lid for outomobile oil tank

Technical field

The utility model relates to automative petrol tank lock fields, more particularly, to a kind of high sealed lock lid for outomobile oil tank.

Background technique

For bulk transport vehicle, fuel tank is provided separately within outside car body, directly naked to be exposed on the external in environment, and environment is disliked It is bad.To guarantee that not having pollutant in fuel tank enters, it is desirable that fuel tank locking closure has very high leakproofness.Leakproofness is better, fuel tank Working environment it is better, use is more longlasting.Existing mailbox locking closure pressing force is insufficient, is entered for a long time using there is also dust The problem of.Meanwhile to meet antitheft requirement, existing fuel tank locking closure is designed with idle running theft-prevention structure, the existing antitheft knot of idle running Structure is complex, at high cost.

Utility model content

The purpose of the utility model is to provide a kind of high sealed lock lid for outomobile oil tank, solve existing automative petrol tank lock sealing Spend low, the problem for the theft-prevention structure complexity that dallies.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of high sealed lock lid for outomobile oil tank, Including shell, it is fixedly mounted on the intracorporal lock core assembly of shell, lock core assembly includes lock core and the lock tongue that is mounted on lock core；It is described The end of lock core assembly is arranged with pedestal, is equipped with pedestal on pedestal, and the support being sleeved on pedestal, the support is fitted in oil It is fixed on case mouth, it is provided with drive block on the support, is provided with pressure spring between the drive block and the end of pedestal；

One group of convex ribs is provided on the inner wall of the pedestal, lock tongue stretching is stuck between two convex ribs；The drive block and branch It is provided with one group of convex closure on the end face of seat cooperation, the track groove of one group with convex closure cooperation is provided on the support.

To improve leakproofness, it is additionally provided with sealing ring on the pedestal, the support is fitted on sealing ring.

For the reliability for guaranteeing pressure spring assembly, the end of the pedestal is fixedly installed U-shaped fixed frame, described pressure spring one end It is placed in U-shaped fixed frame.

For the reliability for guaranteeing pedestal and pedestal assembly, one group of cross spacing muscle and vertical is provided on the outside of the pedestal Limit rib is provided with the limiting groove with cross spacing muscle and the cooperation of vertical spacing muscle on the inner wall of the pedestal.

To meet the anti-theft function that dallies, the end of the lock core is provided with eccentric shaft, what the lock tongue and eccentric shaft cooperated It is arranged fluted on end face, is provided with ejector spring between the lock tongue and the outer housing of lock core assembly.

The utility model has the beneficial effects that the utility model passes through the cooperation of lock tongue and pedestal, make lock core assembly and pedestal It is fixed together, rotation lock core assembly rotates drive block relative seat, and the convex closure on drive block is climbed out of out of track groove, passes Motion block moves up extruding pressure spring, increases pressure spring force, so that the power for being pressed in support on reservoir port increases, to improve leakproofness. The structure makes each of tank cap lock to press together by the strong pressure of pressure spring, big to the pressure of reservoir port, and pressure spring can Moment provides pressing force, to improve the leakproofness of tank cap lock.The sealing ring meets compressive strain, to further increase tank cap lock Leakproofness.The U-shaped fixed frame guarantees that pressure spring not will pop up under pressure.Cross spacing muscle on the pedestal and perpendicular Guarantee the reliability that pedestal and pedestal fixation and power are transmitted to limit rib.The fit structure of the lock core and lock tongue guarantees lock tongue energy Enough pop-ups and timely return, when the key is withdrawn, lock tongue return under the action of lock core make lock tongue and base-separation, realize shell The idle running of body, to reach the anti-theft function of tank cap lock.

Below with reference to drawings and examples, the utility model is described in detail.
