Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
The locking fuel lid of one as shown in Figure 1, comprise oil cap seat 1, be sheathed on the shell 2 of oil cap seat 1 outside, in oil cap seat 1, spline is provided with interlock seat 3, shell 2 is provided with blocking device, blocking device comprises and is fixedly connected with lock housing 41 with shell 2, lock core (not shown) is provided with in lock housing 41, it should be noted that, lock housing 41 is provided with the key hole inserted for key, the bottom of lock housing 41 is inserted in interlock seat 3, the bottom of lock housing 41 is provided with the locking bolt 42 driven by lock core, locking bolt 42 coordinates form engaging and disengaging gear with interlock seat 3, the inwall of shell 2 is circumferentially provided with some spacing preiections 21, one end of the contiguous spacing preiection 21 of oil cap seat 1 is provided with stage portion 11, the outer cover of oil cap seat 1 is provided with annulus 5, annulus 5 is arranged between the bottom of stage portion 11 and the top of spacing preiection 21.
Principle of work of the present utility model is same as the prior art, therefore does not repeat at this.
The locking fuel lid of the one that the utility model provides, by arranging stage portion 11 in one end of oil cap seat 1, and in the outside of oil cap seat 1 sheathed annulus 5, annulus 5 is between the bottom of stage portion 11 and the top of spacing preiection 21, this structure is adopted can not only effectively to prevent from coming off between oil cap seat 1 and shell 2, ensure normal use of the present utility model, compared with prior art simultaneously, the utility model is owing to adopting split to arrange annulus 5 and oil cap seat 1, when pulling shell 2 in the locked state, between spacing preiection 21 and annulus 5, frictional fit is between annulus 5 and stage portion 11, even if now rotation case 2, friction force between annulus 5 and stage portion 11 is still not enough to impel oil cap seat 1 to rotate, thus make guard against theft oil better effects if.
In addition, it is to be noted, even if increase the pulling force of shell 2, because annulus 5 is to being located between spacing preiection 21 and stage portion 11, annulus 5 can be caused because of the stressed phenomenon occurring distortion, tilt, the area of contact between annulus 5 and stage portion 11 is reduced, thus the friction force between annulus 5 and stage portion 11 is also reduced thereupon, oil cap seat 1 now still cannot be driven to rotate, fully reach the effect of guard against theft oil.
The outer wall of oil cap seat 1 is arranged with seal ring 6, annulus 5, to being located between stage portion 11 and seal ring 6, by arranging seal ring 6, both ensure that the stability of annulus 5 installation site, also further increases the leak tightness between oil cap seat 1 and tank filler opening simultaneously.
The inwall of interlock seat 3 is circumferentially provided with some tooth bars 31, and locking bolt 42 is linked by tooth bar 31 and interlock seat 3.When locking bolt 42 stretches out and engages with tooth bar 31, locking bolt 42 is linked with interlock seat 3; When locking bolt 42 is retracted and is departed from tooth bar 31, the interlock event resolves between locking bolt 42 and interlock seat 3.
In order to realize the degassing function of fuel tank, to ensure the normal work of fuel tank, be disposed with spring 7 between interlock seat 3 and the inner bottom part of oil cap seat 1 from top to bottom and pad lid 8, the bottom of oil cap seat 1 is provided with some first row pores 12, be provided with some air discharge duct (not shown)s between interlock seat 3 and the inwall of oil cap seat 1, annulus 5 be provided with some second row pores 51.Packing ring 9 is provided with between interlock seat 3 and pad lid 8.Specifically, when tank internal pressure is too high, the gas in fuel tank upwards pushes against pad lid 8 through first row pore 12, impels spring 7 to compress, occur gap between pad lid 8 and oil cap seat 1, the gas in fuel tank is discharged through first row pore 12, air discharge duct and second row pore 51; When the pressure in fuel tank reduces, spring 7 resets, pad lid 8 shutoff first row pore 12 again, ensures that the gas in fuel tank cannot be discharged.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
