Description
Technical field
The present invention relates to a kind of vehicle-use oil tank cover, in particular a kind of antitheft spill-proof fuel tank cover.
Background technology
Fuel lid refers to the chest for laying in gasoline on automobile, above locking.Shape is square, makes with corrosion-resistant steel, and leak tightness is fine.Only have the round entrance that slight, this mouthful only has the lid of bottle equally large, is convenient to store, and is generally the bottom being placed on automobile.
The feature of current usual products is: 1, key operated be transformed into locking twisting angle be 180 degree, it is bad that hand turns round 180 degree of operation comforts;
2, key is under unlatching or lockup state, and key all can be extracted, and which kind of state fuel lid is in, and rotates fuel lid sometimes under the state of locking to cause user often can not judge, causes fuel lid to damage;
3, key is transformed in locking process in unlatching, does not have gear, and to shelves without fixing, unlatching or lockup state are not felt, and when user takes off fuel lid in opening, the easy sideslip of gear.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of antitheft spill-proof fuel tank cover, realize the function of sealed, burglarproof.
The present invention is achieved by the following technical solutions, the present invention includes lock core assembly, helical pitch hold-down mechanism and lid assembly; Described lock core assembly comprises key, protecting cover, locking plate, lock core, and described lid assembly comprises lid, pallet, bonnet, and described helical pitch hold-down mechanism comprises spring, drive block, helical pitch block and nest; Nest and the inserted connection of pallet, lid is connected with drive block key, and bonnet is connected with helical pitch block key, and drive block is positioned on helical pitch block, and lid is connected with lock core assembly inner blocking type, and pallet is between lid and bonnet, and spring is arranged between bonnet and helical pitch block; Described locking plate is arranged in lock core, key and lock core with the use of, locking plate and lock core are arranged in lid, and protecting cover is connected with lid; Be provided with spring leaf on described lock core, spring leaf is fixed on lid, and lock core is provided with multiple groove, and spring leaf is provided with boss, and described boss and groove fit use.
As one of optimal way of the present invention, described bonnet, drive block, lid and pallet are connected by screw.
Groove on described lock core has three, and the angle of adjacent grooves is 135 °.When fuel lid is in unlatching or lockup state, the boss above spring leaf is just fallen in the groove of lock core, realizes gear sensation.
Described groove is circular, and the boss on spring leaf is circular, is convenient to the turnover of spring leaf convex platform.
As one of optimal way of the present invention, described spring leaf is zigzag, and the head end of spring leaf is arranged on lock core, and end is fixed on lid, and boss is arranged at the head end of spring leaf.
Described lock core is eccentric structure.Lock core eccentric position, higher than the locations on lid, makes lid cannot gyroscopic movement, thus reaches the effect of locked reservoir port.
Be provided with packing seal between pallet and bonnet, between pallet and lid, be provided with packing seal.Drive block drives lid to move downward, and makes two packing seal compressions, touch reservoir port, vehicle fuel tank cap and reservoir port are sealed completely.
The present invention has the following advantages compared to existing technology: the key operated angle of fuel lid of the present invention is 135 °, hand twisting key, and traveling comfort is good; Under the state that key is opened at fuel lid, can not extract, client correctly can judge the state residing for mailbox lid; Fuel lid is when unlatching or locking, and obvious to shelves, when being taken off by fuel lid, gear can not sideslip.
