Abstract
The utility model belongs to the field of fuel tanks of vehicles, in particular to a leakage and theft resistant fuel tank cover, which comprises an outer cover covered outside a fuel tank opening, a clamping claw inner cover sealing the oil tank cover in rotating mode and an elastic connecting member which penetrates through the center of the clamping claw inner cover and pushes the inner cover to the outer cover. A key blocking lock pin and a lock catch which are matched with each other are respectively arranged on a face of the outer cover and a face of the clamping claw inner cover, and the two faces are matched with each other. A sealing ring is arranged on a position of the center of the clamping claw inner cover corresponding to the outer cover. By adopting the technical scheme, fuel tank covers of heavy trucks are convenient to operate and use, and good in leakage and theft resistant effects.
Description
Technical field
The utility model belongs to the vehicle fuel tank field, be specifically related to a kind of in, the fuel tank locking cap of heavy motor vehicle.
Background technology
The reservoir port of fuel tank must seal with fuel lid; With guarantee vehicle jolt, impact or situation such as rollover under fuel oil can not flow out from the fuel tank reservoir port; Thereby avoid accident, because the heavy-duty vehicle oil consumption is big, great amount of fuel oil usually is housed in addition by the fuel leakage initiation; The lawless person usually can take fuel tank locking cap apart, steals the fuel oil in the fuel tank.
At present; In order to realize leakproof and theft-proof purpose; Its structure of prior fuel oil case lid generally is 3～4 elastic claws that finger and symmetrical distribution are set in fuel lid, and clamping is to reach the purpose of the anti-leakage of oil of sealing fuel tank mutually for the draw-in groove of elastic claw and reservoir port inside edge, and lockset control finger combines with reservoir port to reach the locking fuel lid; Prevent that fuel lid from rotating, thereby realize the antitheft purpose of fuel tank.
Though the prior fuel oil case lid can reach leakproof and theft-proof purpose to a certain extent; But still there is following problem in actual the use: 1; Because finger is thin partially, rigidity is poor, and it is firm inadequately to cause fuel lid to combine with reservoir port; Can arbitrarily open at the reservoir port edge, thereby be difficult to reach anti-theft effect preferably; 2, owing to the draw-in groove clamping mutually of adopting 3～4 elastic claws with the reservoir port inside edge, the elastic force of these 3～4 elastic claws is generally all unbalanced; And be very easy to damage; Thereby cause fuel tank locking cap to be difficult to turn, and seal the inhomogeneous oil leakage phenomenon that occurs easily, the more important thing is that fuel oil usually can enter into lockset along finger; And leak out from lockhole, leak preventing effect is good inadequately.
The utility model content
The technical matters that the utility model will solve provides a kind of easy for operation, the heavy vapour fuel tank locking cap of antitheft and good leak-proof effect.
In order to solve the problems of the technologies described above; The utility model provides a kind of leakproof theft-proof fuel tank locking cap, includes the claw inner cap of the enclosing cover that covers on the fuel tank mouth outside, rotary seal fuel tank mouth and pass claw inner cap center it is expressed to the Flexible Connector of enclosing cover; Wherein, enclosing cover is respectively arranged with key interlock lock pin and the snap close that matches with the claw inner cap in the one side of its cooperation, and the cooresponding place of claw inner cap center and enclosing cover is provided with seal ring.
Because the claw inner cap directly is screwed in the fuel tank mouth with sealing fuel tank mouth; Enclosing cover cover on the fuel tank mouth and with the same axle mounting of claw inner cap; Therefore Flexible Connector is crowded together claw inner cap, fuel tank mouth and enclosing cover closely, and the user of service can only directly be screwed to enclosing cover, has only and uses key that the snap close that covers in the outer key interlock lock pin that covers and the claw is connected; The claw inner cap is rotated with enclosing cover; At this moment rotate enclosing cover and just can rotate the claw inner cap simultaneously, when the snap close that covers in the key that outside key makes, covers interlock lock pin and the claw separated, inner cap no longer rotated with enclosing cover simultaneously; How no matter rotate and pull enclosing cover this moment, all can't inner cap be opened.
Adopt the theft-proof fuel tank locking cap of leakproof of technique scheme to have following advantage; 1; Owing to adopted claw inner cap rotary seal fuel tank mouth, key lock pin to be arranged on outer covering, therefore avoided getting into the fuel leakage of lockset through lock pin; The catching inner cap has also been avoided leakage of oil through the extruding and the tight-lipped leakproof fit of fuel tank of Flexible Connector in addition; 2, owing to cancelled the elastic card that traditional fuel tank locking cap adopts, therefore be not easy to damage, and the process of twisting is lighter; 3 and since enclosing cover cover on the fuel tank mouth and with the same axle mounting of claw inner cap, Flexible Connector is crowded together claw inner cap, fuel tank mouth and enclosing cover closely; Therefore the user of service can only directly be screwed to enclosing cover, has only and uses key that the snap close that covers in the outer key interlock lock pin that covers and the claw is connected, and the claw inner cap is rotated with enclosing cover; At this moment rotate enclosing cover and just can rotate the claw inner cap simultaneously; When the snap close that covers in the key that outside key makes, covers interlock lock pin and the claw separated, inner cap no longer rotated with enclosing cover simultaneously, no matter how to rotate this moment and pulled enclosing cover; All can't inner cap be opened, so anti-theft effect is very good.
As preferred version; In order better to seal the fuel tank mouth; Limit described claw inner cap include circular seal receptacle, pawl dish and be arranged on seal receptacle and chuck between prevent the locating dowel pin that it rotates, the one side of said seal receptacle is provided with the seal gasket that matches with fuel tank mouth upper edge, another side is provided with the tubular convexity; Described snap close is arranged on the convexity, described pawl dish outward flange be provided with the fuel tank mouth in the claw that cooperates of side bayonet slot.
As preferred version; For better elasticity connects enclosing cover and claw inner cap; Described Flexible Connector includes pipe link, spring and spring end cap, and said pipe link one end is connected to the enclosing cover center, and the other end passes the inner cap center successively and links to each other with spring and with the spring end cap.
As preferred version,, also be provided with the balance pad of an annular between enclosing cover and the claw inner cap in order to prevent rocking relatively of inner cap and enclosing cover.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the theft-proof fuel tank locking cap structure of a utility model leakproof exploded perspective view;
