The utility model content
The purpose of this utility model provides a kind of tank cap lock with lost motion functionality, and when the solution tank cap lock was not opened, firmly the rotary oil tank lock caused the problem of tank cap lock damage.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of tank cap lock with lost motion functionality, include the fuel tank locking closure and the tank cap lock base that cooperate installation, and described tank cap lock base is provided with switch block; Described fuel tank locking closure is provided with and cooperates the lock housing of installing with switch block and place lock core assembly in the lock housing; Also be provided with dead bolt, dead bolt is pressed on the lock core assembly by stage clip, is provided with unidirectional ratchet on the described switch block inwall, is provided with latch on dead bolt and the face that ratchet cooperates.
For improving the locking power of dead bolt and switch block, be provided with drive block at the lock core assembly, be provided with the boss suitable with dead bolt on the drive block.
Described drive block lateral wall cooperates with the inside wall of dead bolt, is provided with boss on the lateral wall of drive block.
For making the stressed even of lock housing and switch block, described dead bolt has two, is arranged symmetrically on the lock housing.
Install for convenient, be provided with one group of fixed block on the described switch block, tank cap lock covers and is provided with one group of groove that matches, and switch block and fuel tank locking closure are connected and fixed by fixed block and groove.
For improving the dirt exclusion capabilities of lock core, described tank cap lock covers to be provided with and prevents that lock core from falling into the dust cap of dust.
The beneficial effects of the utility model: cooperate with ratchet by dead bolt, so that tank cap lock is in locked situation, rotate the fuel tank locking closure, fuel tank locking closure and tank cap lock base skid, the tank cap lock base is motionless, prevent from firmly twisting in the situation that tank cap lock is not opened the fuel tank locking closure, the stressed locking plate that is arranged on the tank cap lock base that causes of tank cap lock base damages, and makes the tank cap lock not tight.Described drive block boss can guarantee that under key operated state fuel tank locking closure and tank cap lock base the rotation of skidding can not occur; Dust cap can the Effective Raise tank cap lock dirt exclusion capabilities.
Below in conjunction with drawings and Examples, the utility model is described in further detail.

Fig. 2 is the explosive view of tank cap lock internal construction.
Fig. 3 is the fiting relation figure of lock core assembly, drive block, dead bolt and switch block.
The specific embodiment
Embodiment, as shown in Figures 1 to 3, a kind of tank cap lock with lost motion functionality includes the fuel tank locking closure 1 and the tank cap lock base 5 that cooperate installation, and described tank cap lock base 5 is provided with switch block 4; Described fuel tank locking closure 1 is provided with and cooperates the lock housing 2 of installing with switch block 4 and place lock core assembly 3 in the lock housing 2; Also be provided with dead bolt 6, dead bolt 6 is pressed on the lock core assembly 3 by stage clip 7, is provided with unidirectional ratchet 42 on described switch block 4 inwalls, is provided with latch 61 on dead bolt 6 lateral surfaces that cooperate with ratchet 42.When tank cap lock is locked, along opening direction rotary oil tank locking closure 1, when pressure reaches the contact stress that is enough to overcome 4 of dead bolt 6 and switch blocks, dead bolt 6 is stressed upon under the effect of stage clip 7 in the retraction lock housing 2, lock housing 2 is in switch block 4 interior rotations, so that the fuel tank locking closure 1 that is fixedly connected with lock housing 2 rotates with respect to the tank cap lock base 5 that is fixed together with switch block 4, i.e. fuel tank locking closure 1 idle running, tank cap lock can not be opened; If opposite spin, the latch 61 on the dead bolt 6 are stuck in switch block 4 ratchets 42, fuel tank locking closure 1 drives tank cap lock base 5 and revolves tighter and tighter.When tank cap lock is opened, along the opening direction rotation, just can open tank cap lock.
