The specific embodiment

Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.

Consult Fig. 1 to shown in Figure 8, the technical scheme of present embodiment is achieved in that a kind of protecting against shock AGO Automotive Gas Oil case lid, and it comprises valve body 4, handle 1; The upper end of valve body 4 is located in handle 1 activity, on the valve body 4 of handle 1, is concaved with groove 11, is provided with rotary vane 3 in the groove 11; Like Fig. 5, shown in Figure 6; The inwall of groove 11 is provided with rubber-like cantilever 5, and the outer wall of rotary vane 3 is provided with the ratchet 6 with cantilever 5 couplings, like Fig. 6, Fig. 7, shown in Figure 8; Cantilever 5 has the square edge 51 perpendicular with the inwall of groove 11; Ratchet 6 has the square edge 61 perpendicular with the outer wall of rotary vane 3, is installed with torsion spring 2 between handle 1 and the rotary vane 3, offers the arc opening 7 of a pair of symmetry on the rotary vane 3; On the handle 1 of rotary vane 3, convex with a pair of backing block 8 that can in arc opening 7, slide; Each backing block 8 be able to embed a wherein end of arc opening 7, and when the other end rotation that is positioned at arc opening 7 to backing block 8 when handle 1 was less than or equal to the angle of arc opening 7, handle 1 produced relative rotation with the interaction energy of valve body 4 through torsion spring 2; The other end rotation that is positioned at arc opening 7 to backing block 8 when handle 1 is during greater than the angle of arc opening 7; Backing block 8 goes to the other end of arc opening 7; And drive rotary vane 3 rotations, and the square edge 51 that the square edge 61 of ratchet 6 drives cantilevers 5 rotates, and valve body 4 rotations realize unscrewing.

Like Fig. 3, Fig. 5, Fig. 6, shown in Figure 8; Cantilever 5 also has the inwall inclined side 52 in obtuse angle with groove 11; Ratchet 6 also has the outer wall inclined side 62 in obtuse angle with rotary vane 3; When handle 1 is positioned at end when rotation of arc opening 7 to backing block 8, the inclined side 62 of ratchet 6 is conflicted with the inclined side of cantilever 5 52, and forces cantilever 5 to be upspring.

Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; Torsion spring 2 with the fixed form of rotary vane 3 and handle 1 is in the present embodiment: the center of rotary vane 3 is provided with first draw-in groove 9; Handle towards rotary vane 3 is provided with second draw-in groove 10; The two ends of torsion spring 2 are formed with 21, two clamps 21 of a pair of clamp that is parallel to each other and embed respectively in first draw-in groove 9 and second draw-in groove 10.

Be the fuel lid of screwing when present embodiment is designed to up time rotary handle 1, for unscrewing fuel lid, and the angle of the arc opening 7 of present embodiment is 90 ° during left-hand revolution handle 1.

When handle 1 receives an impulsive force, like Fig. 1, Fig. 6, Fig. 7, shown in Figure 8,, this impulsive force impacts if being cw, and then fuel lid can more be screwed on the automobile fuel filler pipe; Impact if this impulsive force is a conter clockwise, then present embodiment has one 90 ° cushion stroke, and when impulsive force was in the state of effect handle 1, impulsive force forced handle 1 to rotate counterclockwise; If the angle of handle 1 rotation does not exceed 90 °, then the backing block 8 on the handle 1 only rotates counterclockwise separately in arc opening 7, at this moment; Torsion spring 2 is twisted state and has torsion, but this torsion can't drive valve body 4, when impulsive force removes; Rotary vane 3 and valve body 4 only receive the torsion of torsion spring 2, and at this moment, the torsion spring 2 that is in twisted state discharges torsion; Can force handle 1 revolution, this moment, valve body 4 still kept screwing state, and handle 1 guarantees to produce relative rotation with the effect of valve body 4 through torsion spring 2; Have a cushion stroke, it is loosening easily to have solved valve body 4, is prone to the problem of oil and gas leakage phenomenon.

When unscrewing fuel lid, like Fig. 1, Fig. 6, shown in Figure 7, left-hand revolution handle 1, the angle that needs rotation is greater than 90 °; Through test of many times, the angle that the general job personnel only need rotation amplitude to be about 120 ° can unscrew fuel lid, and its principle of work is following: backing block 8 conter clockwises go to the other end of arc opening 7, because the angle of rotation has surpassed 90 ° of strokes of arc opening 7; Backing block 8 drives rotary vane 3 and rotates, and at this moment, the square edge 51 of square edge 61 conter clockwise Operating valve bodies 4 upper cantilevers 5 of ratchet 6 on the rotary vane 3 is after two pairs of square edges contacts; Can not upspring and stagger, then valve body 4 receives the effect rotation of cantilever 5 and realizes unscrewing, in the whole process; Handle 1 has all rotated 120 ° with valve body 4, though in preceding 90 ° of handle 1 motion, valve body 4 does not rotate; Back 30 ° of handle 1 motion then drive 30 ° of valve body 4 rotations, still, and behind the disengaging of the fuel lid after unscrewing filler neck; Torsion spring 2 discharges torsion again, drives rotary vane 3 and 90 ° of valve body 4 left-hand revolutions, and 4 benefits of valve body this moment have been revolved 90 °; Torsion spring 2 returns to state of nature then, and is as shown in Figure 6,8 initial positions that are in arc opening 7 again of backing block.

When screwing fuel lid, like Fig. 1, Fig. 6, shown in Figure 8, clockwise rotate handle 1, drive rotary vane 3 through the stop on the handle 1 fast 8 and rotate together with valve body 4; When valve body 4 is tightened on the automobile fuel filler mouth of pipe, continue rotary handle 1 and drive rotary vane 3, the rubber-like cantilever 5 of valve body 4 will be by ratchet 6 extruding of rotary vane 3; As shown in Figure 8, during clickwise, the inclined side 62 of ratchet 6 contacts with the inclined side 52 of cantilever 5; Because ratchet 6 contacts with cantilever 5 and is the dip plane, then cantilever 5 can be extruded and upspring, at every turn through behind the ratchet 6; Will produce " " sound feed back to the user, explain that fuel lid has been tightened.

Above embodiment is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the people that is familiar with this technology understand the content of the utility model and implements; Can not limit the protection domain of the utility model with this; All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the utility model.
