Detailed description of the invention
Embodiment, as Fig. 1 is to shown in 11, and a kind of fuel tank lock locking structure, including housing 2, the bottom coordinated with housing 2
10, the lock core 6 being arranged in housing 2, lock housing 5 and blade 4.It is positioned at lock housing 5 installation place in described housing 2 and is provided with projection, convex
Being set with fixed block 7 on post, projection and fixed block 7 are provided with location structure, and the fixed block 7 made can not rotate on projection.
It is arranged with relatively turnable block 9 outside described fixed block 7, between fixed block 7 and block 9, is provided with return torsion spring 8.Described block
It is relatively set with two block boss 91 on the outer wall of 9, described fixed block 7 is provided with two deformable pivoted arms 71, pivoted arm
71 are connected with fixed block 7 by one end, and the end of pivoted arm 71 is provided with the pivoted arm grab 711 coordinated with block boss 91.Install
Time, return torsion spring 8 is under original state, and now block boss 91 separates with pivoted arm buckle 711.
Being additionally provided with latch segment 3 in described housing 2, the external diameter of latch segment 3 is identical with the internal diameter of housing 2, makes latch segment 3
Outer wall leans against on the inwall of housing 2.One group of latch segment boss 31, latch segment boss 31 it is provided with on the inner ring of described latch segment 3
Be the ramp structure suitable with pivoted arm grab 711 back side along clockwise direction, latch segment boss 31 be in the counterclockwise direction with
What pivoted arm grab 711 end face coordinated faces structure directly.
The bottom of described latch segment 3 is provided with one group of locking latch 32, and clockwise of latch 32 of locking is inclined-plane
Structure, anticlockwise for facing structure directly.Two cantilevers it are provided with latch segment 3 on the end face that described bottom 10 coordinates
102, the centre position of cantilever 102 is fixed together with bottom 10, and the two ends of cantilever 102 are each provided with a locking grab 101,
The side of locking grab 101 is for facing structure directly, and opposite side is ramp structure, and that locks grab 101 faces and lock latch 32 directly
Facing cooperation directly, the inclined-plane of locking grab 101 coordinates, as shown in Figure 2 with the inclined-plane of locking latch 32.
The bottom of described block 9 is provided with the back-up ring 92 coordinated with lock core 6, back-up ring 92 is symmetrically arranged with one and concaves
V-type limiting section 921, the bottom oblique cutting of lock core 6 makes block 9 to rotate freely in the range of 90 °, such as Fig. 5 in back-up ring 92
Shown in.4 lock housing grooves 51 suitable with blade 4, the most symmetrically arranged two locks it are evenly arranged with on the inwall of described lock housing 5
The sidewall of shell groove 51 is faces structure directly, and two further pairs claims the sidewall of lock housing groove 51, one of them sidewall for facing structure directly, another
Individual sidewall is ramp structure, as shown in Figure 10, Figure 11.
When fuel tank lock is contained on reservoir port locking, now, the pivoted arm grab 711 on fixed block 7 and the gear on block 9
Block boss 91 is in released state, as shown in Figure 3.Rotate clockwise housing 2, drive fixed block 7 to rotate together, angle from figure
Seeing, fixed block 7 is rotate in an anti-clockwise direction, makes the end face of pivoted arm grab 711 be pressed in facing directly of latch segment boss 31 locked, this
Time, continuing the housing 2 that turns clockwise, latch segment 3 rotates with fixed block 7, as in figure 2 it is shown, the locking latch on latch segment 3
The inclined-plane of 32 mutually extrudes with the inclined-plane of locking grab 101, makes cantilever 102 be deformed, and locking latch 32 strides across locking grab
101, latch segment 3 and bottom 10 produce relative motion, thus realize in the locked condition, being rotated further housing 2, housing clockwise
2 dally on bottom 10, reach the prompt facility that dallies, and remind operator's fuel tank lock to have locked up with reservoir port.Now, inverse
When clockwise rotates housing 2, from the point of view of Fig. 3, fixed block 7 now does rotationally clockwise with housing 2, pivoted arm card
The back side of hook 711 coordinates with the inclined-plane of latch segment boss 31, due to the pivoted arm grab 711 on now fixed block 7 with on block 9
Block boss 91 is in released state, therefore, when the back side of pivoted arm grab 711 extrudes the inclined-plane of latch segment boss 31, and pivoted arm
71 are deformed, and make pivoted arm grab 711 separate with latch segment boss 31, and fixed block 7 and latch segment 3 produce relative motion, thus
Bottom 10 can not be further driven to rotate, it is achieved the idle running of the relative bottom 10 of housing 2, now, rotate housing 2 counterclockwise, it is impossible to
Fuel tank lock is back-outed from reservoir port, reaches antitheft effect of dallying.In this case, the position relationship of lock core 6 and lock housing 5 is such as
Shown in Figure 11, the blade 4 in lock core 6 stretches out and is in sidewall and is in the lock housing groove 51 facing structure directly, makes lock core 6 not turn
Dynamic, now, bottom lock core 6 with block 9 bottom matching relationship as shown in Figure 5.
When fuel tank lock is backed out by needs from reservoir port, by key rotation lock core 6, make lock core 6 half-twist, blade 4
It is from sidewall and faces the lock housing groove 51 of structure directly and proceed to side for facing structure directly, in opposite side is the lock housing groove 51 on inclined-plane.Meanwhile,
Lock core 6 drives block 9 to rotate, and makes the block boss 91 on block 9 coordinate stuck with the pivoted arm grab 711 on fixed block 7, such as figure
Shown in 4.Another mistake hour hands rotate housing 2, and housing 2 drives block 9 to rotate counterclockwise together with lock core 6, i.e. block in terms of Fig. 4 direction
9 rotate clockwise.When pivoted arm grab 711 goes to contact with latch segment boss 31, due to pivoted arm grab 711 with block boss
91 is stuck, therefore, and can not compression when encountering latch segment boss 31 so that pivoted arm grab 711 squeezes with latch segment boss 31
Forcing together, fixed block 7 drives latch segment 3 to rotate counterclockwise together while rotating counterclockwise, now, and the lock on latch segment 3
Facing directly of tight latch 32 coordinates, with facing directly of locking grab 101, compressions so that latch segment 3 drive bottom 10 together counterclockwise just
To rotation, fuel tank lock is back-outed from reservoir port.
When fuel tank lock is screwed on fuel port time, turn clockwise housing 2, and housing 2 drives lock housing 5 to turn together with lock core 6
Dynamic, make lock core 6 be positioned at the position shown in Fig. 6, be rotated further housing 2, blade 4 coordinates retraction with the inclined-plane of lock housing groove 51, makes
Lock core 6 rotates relative to housing 2 and lock housing 5, makes blade 4 go to sidewall and is in the lock housing groove 51 facing structure directly, it is achieved on Zi Dong
Lock.Now, being rotated further housing 2, housing 2 drives fixed block 7 to rotate clockwise together with block 9, i.e. in terms of Fig. 4 direction, Gu
Determine block 7 and block 9 rotate in an anti-clockwise direction, when the end face of pivoted arm grab 711 is pressed in when facing directly upper of latch segment boss 31, in pressure
Under the effect of power, making pivoted arm 71 stretch out deformation, make pivoted arm grab 711 separate with block boss 91, block 9 is at return spring
Effect under counterclockwise rotate, return to the position under lockup state, now, block 9 also returns to the matching relationship of lock core 6
Position shown in Fig. 5.Now, fixed block 7 moves clockwise together with latch segment 3 locking, due to the rotation of housing 2 now
Power is deformed required power less than cantilever 102, and therefore, now, housing 2 can drive bottom 10 to move together, thus realizes
Fuel tank lock screws with fuel port, after screwing, continues to go into overdrive, and cantilever 102 is deformed, and makes housing 2 produce idle running.
