The specific embodiment
The utility model fuel tank of vehicle lock provides following function:
1. the fuel tank of vehicle internal gas pressure is regulated automatically, guarantees the safety and normal use of fuel oil;
2. guarantee the non-volatile and leakage of fuel oil;
3. guaranteeing that fuel tank is locked in is not damaged in the use and loses.
For this reason, see figures.1.and.2, the utility model fuel tank of vehicle lock comprises base 23, loam cake 6, lock core 21, dead bolt 16, switch block 13 and limited block 8, wherein, switch block 13 and dead bolt 16 intermesh by dentalation, also are provided with to be used for the self-regulating unidirectional air pressure regulator of fuel tank internal gas pressure, hermetically-sealed construction and to be used for antitheft idling structure.
With reference to Fig. 2 and Fig. 5, in the embodiment of the utility model fuel tank of vehicle lock, unidirectional air pressure regulator is between the bonnet 14 of snapping on the inner chamber of switch block 13 and switch block 13 end faces, comprise the dividing plate that is installed in switch block 13 inner chambers 33 and be positioned at sealing ring 34, press spring base 35 and the stage clip of installing successively below it 36 that stage clip 36 is fixed in the truncated cone-shaped groove of the boss of press spring base 35 and bonnet 14.
The course of work of unidirectional air pressure regulator is: when the fuel tank internal gas pressure drops to certain numerical value, because fuel tank inner and outer air pressure difference is to the active force of press spring base 35 force value greater than stage clip, press spring base 35 moves downward, stage clip 36 is compressed, produce the slit between sealing ring 34 and the dividing plate 33, gas constantly enters in the fuel tank from the slit of switch block 13 and the hole of bonnet 14.When the fuel tank internal gas pressure slowly is elevated to certain numerical value, fuel tank inner and outer air pressure difference is to the active force of press spring base 35 force value less than stage clip, and press spring base 35 moves upward, stage clip 36 elongations, sealing ring 34 is closed with dividing plate 33 slits, guarantees the normal supply of the non-volatile and vehicle fuel of fuel oil.
With reference to Fig. 2, Fig. 6 and Fig. 7, in the embodiment of the utility model fuel tank of vehicle lock, hermetically-sealed construction comprises the latch segment 11 that links to each other respectively with base 23, switch block 13 and the corrosion resistant plate 7 that snaps together with the port of loam cake 6, switch block 13 has equally distributed 3 brace rods 15, and by the lower end of brace rod 15 and corresponding 3 inclined-plane sliding-contacts of latch segment 11.Be provided with the snap ring 28 and the card pad 29 of mutual snapping between the draw-in groove on switch block 13 tops and the corrosion resistant plate 7, be provided with sealing ring 26 between corrosion resistant plate 7 and the fuel tank mouth of pipe seat.
With reference to Fig. 2, Fig. 3 and Fig. 6, the course of work of hermetically-sealed construction is: when switch block 13 was in opening, the boss of limited block 8 and base 23 was in aligned position.The dentalation of the dentalation of dead bolt 16 and switch block 13 is in engagement.Be in the mated condition that is in contact with one another between drive block 20 and the dead bolt 16.Dead bolt 16,, can only move with switch block 13 so dead bolt 16 can not retreat because do not have the slit between drive block 20 and the dead bolt 16 in the time spent of doing that is subjected to power.With the boss of limited block 8 and base 23 alignment filler neck seat screens groove, the lock body loam cake 6 that turns clockwise makes it to drive dead bolt 16, switch block 13, base 23 and does simultaneously and turn clockwise.By 3 brace rods of switch block 13 and the routing motion between latch segment 11 corresponding 3 inclined-planes, switch block 13 drives by snap ring 28, card and fills up 29 corrosion resistant plates 7 that connect with the sealing ring 26 and the locking of filler neck seat that are provided with between corrosion resistant plate 7 and the oil pipe mouth seat, thereby guarantees the non-volatile and leakage of fuel oil.
With reference to Fig. 2, Fig. 3 and Fig. 4, in the embodiment of the utility model fuel tank of vehicle lock, idling structure comprises lock core 21, dead bolt 16 and switch block 13, dead bolt 16 has the endoporus that the cross section is an octagon, be provided with the drive block 20 that cooperates with lock core 21 in the endoporus, the cross section of drive block 20 is an octagon, and wherein one group of opposite side and dead bolt 16 are for contacting cooperation, when drive block 20 half-twists, there is the bar shaped gap in another group opposite side with dead bolt 16 when cooperating.
The course of work of idling structure is: after dead bolt 16 drives switch blocks 13 and base 23 and is screwed into the position, key 32 is clockwise rotated 90 °, switch block 13 promptly is in lockup state.Extract key 32, antitheft idling structure just works.This moment, the boss of limited block 8 and base 23 was in misalignment position.The dentalation of dead bolt 16 still is in engagement with the dentalation of switch block 13.Become the mated condition that is in the gap between drive block 20 and the dead bolt 16.Dead bolt 16 because have the gap between drive block 20 and the dead bolt 16, tooth idle running phenomenon occur jump so dead bolt 16 can retreat in the time spent of doing that is subjected to power when stressed, just produce relative motion between dead bolt 16 and the switch block 13 like this.Forward switch block 13 to opening without key 32, lock body can not be taken off from the filler neck seat, so not only prevented that fuel tank lock lock body is destroyed but also guaranteed that fuel oil is not stolen no matter rotate how many circles counterclockwise.
See figures.1.and.2, in the embodiment of the utility model fuel tank of vehicle lock, bonnet 14 is equipped with theft-resistant link chain 17, and the other end of theft-resistant link chain 17 and filler neck seat be hook company mutually.When automobile factory when car load assembles, the other end of theft-resistant link chain 17 is hooked on the filler neck seat, like this, in use do not cause damage on the ground with regard to can fuel tank not being locked because of artificial carelessness, more can be because of forgetting the loss of locking the fuel tank lock and causing the fuel tank lock after refueling.
