Turn edge under said spiral cover has, the lower end that this time turns edge is not higher than the upper end of the thread segment of said cock.Said cock and spiral cover are through being connected the rotation assembling of the fix shaft axial limiting between lock tube and the lock core.Said lockhole is the arc lockhole.
The fuel tank plug scheme of the utility model is: a kind of Anti-theft oil tank plug; The Anti-theft oil tank plug comprises that cock and axial limiting ground rotate the spiral cover that is assemblied in cock top; Said cock comprises that its underpart is provided be used for fuel tank on the thread segment that cooperates of open-top screw thread and be located in the cock or the lock tube on cock top; Said spiral cover comprises and is used for when the cock occlusion of openings, preventing fixing lock core on lid that cock exposes and the lid; Said lock core is inserted in the lock tube, and lock core is provided with by key and under lockup state and released state, drives and the dead bolt of action of stretching, contract, and said lock tube is provided with the lockhole that only revolves, separates cooperation with the dead bolt of the action of stretching, contract.
Turn edge under said spiral cover has, the lower end that this time turns edge is not higher than the upper end of the thread segment of said cock.Said cock and spiral cover are through being connected the rotation assembling of the fix shaft axial limiting between lock tube and the lock core.Said lockhole is the arc lockhole.
Only revolve under the state at spiral cover and cock, can turn on the fuel tank plug, carry out oiling work, under the state of spiral cover and cock turning fit, twist just idle running of spiral cover, can not open the fuel tank plug, and this two states needs the action of key actuated dead bolt to realize; And spiral cover can cover cock, prevents that cock from exposing to make staff can contact cock, does like this, and the people must drive cock rotating opening fuel tank through turning the spiral cover that only revolves state; The integral tank plug structure is difficult to be destroyed in addition, so can play good antitheft effect.
Description of drawings
Fig. 1 is the fuel tank scheme drawing;
Fig. 2 is a fuel tank plug structure scheme drawing.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Fuel tank embodiment
A kind of vehicle anti-theft fuel tank as shown in Figure 1 comprises fuel tank, and fuel tank is provided with oil inlet 21 and sewage draining exit 22 (as other embodiments, also can only establish oil inlet), is equipped with the Anti-theft oil tank plug on oil inlet 21 and the sewage draining exit 22.The concrete structure of Anti-theft oil tank plug is the embodiment of face as follows.
Fuel tank plug embodiment
Like Fig. 2, the Anti-theft oil tank plug comprises a cock 7, and the upper end button of cock 7 is established a spiral cover 11, and the lower end outer peripheral face of cock 7 is provided with screw thread, cooperates with cooresponding oil inlet or sewage draining exit helixseal; The cock internal fixation is provided with lock tube 6; And be fixed with lock core 13 on the spiral cover 11, like Fig. 2, lock core 13 forms the position relation of inserting lock tube 6; Be connected with an axial location axle 12 between lock tube 6 and the lock core 13; These axial location axle 12 axial limiting lock tubes 6 and lock core 13, and make their normal-running fiies, thus realize cock 7 and spiral cover 11 axial limiting ground normal-running fiies.Offer lockhole on lock tube 6 perisporiums, be provided with the dead bolt 5 that driven by key 8 in the lock core 13, dead bolt 5 stretches out the insertion lockhole when lock-out state, and spiral cover 11 and cock 7 are only revolved, and when released state, makes dead bolt 5 withdrawals, makes spiral cover 11 and cock 7 turning fites.Lockhole is the arcuate socket or the groove of 90 ° or other angles.
