Abstract
The utility model discloses a kind of vehicle fuel tank cap with lost motion functionality, the lower cover that comprises upper cover, is threaded with reservoir port, in described upper cover, be pressed with lock housing, the dead bolt that lock core is installed in described lock housing and is driven by lock core, covers under described and is provided with the draw-in groove coordinating with dead bolt.The utility model by upper cover upper lock tongue with under cover coordinating of draw-in groove, in the time that dead bolt stretches into draw-in groove, upper cover and lower cover are fixed together, together rotate, thereby turn the screw thread that lower cover coordinates with reservoir port, open or close fuel lid; When in dead bolt retraction lock housing, upper cover and lower cover are rotationally connected, and upper cover can freely rotate, and after realizing fuel tank and locking, when rotary upper cover, upper cover freely rotates, and can not drive the threads turn between lower cover and reservoir port, improve theftproof performance.
Description
Technical field
The utility model relates to vehicle fuel tank cap field, especially relates to a kind of vehicle fuel tank cap with lost motion functionality.
Background technology
The reservoir port of fuel tank must seal with fuel lid, with ensure vehicle jolt, impact or the situation such as rollover under fuel oil can not flow out from the reservoir port of fuel tank, thereby the accident of avoiding fuel leakage and cause, in addition because heavy-duty vehicle oil consumption is large, great amount of fuel oil is usually housed, lawless person is many can take fuel tank locking cap apart, steals the fuel oil in fuel tank.
Existing fuel lid can reach leakproof and antitheft object to a certain extent, but in actual use, still there is following problem: because finger is partially thin, rigidity is poor, cause fuel lid to be combined with reservoir port firm not, reach the object of opening fuel lid by prizing destruction dead bolt, thereby be difficult to reach good anti-theft effect.As Chinese Patent Application No. is: 2012204739748 disclosed a kind of tank cap locks with lost motion functionality, include and coordinate fuel tank locking closure and the tank cap lock base installed, described tank cap lock base is provided with switch block; Described fuel tank locking closure is provided with and coordinates the lock housing of installing with switch block and be placed in the lock core assembly in lock housing; Also be provided with dead bolt, dead bolt is pressed on lock core assembly by stage clip, on described switch block inwall, is provided with unidirectional ratchet, on the dead bolt lateral surface coordinating, is provided with latch with ratchet.Described fuel tank locking closure can rotate relative to tank cap lock base, can prevent in the time that tank cap lock is not opened, and firmly tank cap lock is outwarded winding, and destroys tank cap lock, can be widely used in automotive oil tank and lock.Although above-mentioned patent coordinates latch rotation by ratchet is set, fuel tank locking closure can rotate the object that reaches antitheft relative to tank cap lock base.But this kind of structure, in the time of new-product development, need to newly be opened corresponding ratchet and latch mould.Complex structure, productive costs is high, later maintenance, detachable maintaining difficulty is large, often directly does and scraps processing.
Utility model content
The purpose of this utility model is to provide a kind of vehicle fuel tank cap with lost motion functionality, and while solving existing fuel lid self-locking, upper cover can not independently dally, and tank cap lock anti-theft is poor, the irrational problem of structure design.
The utility model solves the technical scheme that its technical matters adopts: a kind of vehicle fuel tank cap with lost motion functionality, the lower cover that comprises upper cover, is threaded with reservoir port, in described upper cover, be pressed with lock housing, the dead bolt that lock core is installed in described lock housing and is driven by lock core, covers under described and is provided with the draw-in groove coordinating with dead bolt.
Further, between described dead bolt one end and lock-shell lining, be provided with stage clip, dead bolt is positioned at the below of lock core, and on dead bolt, is provided with the resettlement groove coordinating with lock core end.
In order to improve oil tank cover sealing, cover under described and be also provided with automatic voltage regulation assembly, between described lower cover and reservoir port, be also provided with seal ring.
In order to prevent that dust from entering lock core, cover on described and be also provided with seal cover cap.
The beneficial effects of the utility model: by upper cover upper lock tongue with under cover coordinating of draw-in groove, in the time that dead bolt stretches into draw-in groove, upper cover and lower cover are fixed together, together rotate, thereby turn the screw thread that lower cover coordinates with reservoir port, open or close fuel lid; When in dead bolt retraction lock housing, upper cover and lower cover are rotationally connected, and upper cover can freely rotate, and after realizing fuel tank and locking, when rotary upper cover, upper cover freely rotates, and can not drive the threads turn between lower cover and reservoir port, improve theftproof performance.This kind of structure arranges rationally, when new-product development, only need to lock housing and under cover fluting, removed the die cost of offering separately ratchet and latch for different size fuel lid from, saved productive costs, improved production efficiency.And between lock housing and dead bolt, increase the power that the stage clip that is connected provides dead bolt to slide, prevent the generation that when dead bolt uses for a long time, dead bolt does not eject situation, raising fuel lid service life.By between lower cover and reservoir port, seal ring being set, and under cover automatic voltage regulation assembly be set, in ensureing fuel tank leak tightness, control fuel tank internal stable gas pressure, improve leak tightness and the safety of fuel lid.By seal cover cap being set on the lock core often plugging key, prevent that dust from entering, extend lock core service life.
Below with reference to drawings and Examples, the utility model is described in detail.

Detailed description of the invention
Embodiment, as shown in Figure 1 to Figure 3, a kind of vehicle fuel tank cap with lost motion functionality, the lower cover 21 that comprises upper cover 11, is threaded with reservoir port, in described upper cover 11, be pressed with lock housing 13, the dead bolt 14 that lock core 12 is installed in described lock housing 13 and is driven by lock core 12, is provided with the draw-in groove 211 coordinating with dead bolt on described lower cover 21.Between described dead bolt 14 one end and lock housing 13 inwalls, be provided with stage clip 15, dead bolt 14 is positioned at the below of lock core 12, and on dead bolt 14, is provided with the resettlement groove 141 coordinating with lock core 12 ends.
On described lower cover 21, be also provided with automatic voltage regulation assembly 22, between described lower cover 21 and reservoir port, be also provided with seal ring 23.In ensureing fuel tank leak tightness, control fuel tank internal stable gas pressure, improve leak tightness and the safety of fuel lid.On described upper cover 11, be also provided with seal cover cap 111.By seal cover cap 111 being set on the lock core 12 often plugging key, prevent that dust from entering, extend 12 service lifes of lock core.
When installation, screwed one side on fuel lid lower cover 21 is fixed on reservoir port by the mode of rotation, lower cover 21 is having seal ring 23 with reservoir port cooperation place, ensures that fuel lid normally packs the leak tightness after reservoir port into.
In the time of self-locking, key is by rotarily driving lock core 12, and the rotation of lock core 12 is retracted in resettlement groove 141 dead bolt 14, and under this state, fuel lid upper cover 11 is free to idle running, and lower cover 21 is fastened on reservoir port, and reservoir port is blocked.In the time unblanking, key is by rotarily driving lock core 12, the rotation of lock core 12 and make dead bolt 14 eject resettlement groove 141 under the effect of dead bolt stage clip 15 spring forces to be pressed in the corresponding draw-in groove 211 of lower cover 21, the now rotation of upper cover 11 drives the rotation of lower cover 22, fuel lid rotates reservoir port, and reservoir port is opened.
