Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in Figure 1 and Figure 2, a kind of safety valve of oil tank door gear described in the utility model, including flexible plug mechanism, push away
Draw trigger mechanism and safety switch 9；Oil suction base 11 is set in fuel tank 1 to be connected with fuel sucking pipe 12；Taper in flexible plug mechanism
Plug 7 is held out against in oil suction base 11 under the effect of spring 6；Taper plug 7 touches with setting push-and-pull at the mating connection of oil suction base 11
Mechanism is sent out, push-and-pull trigger mechanism is made up of handle 10 and conducting body 8, and conducting body 8 can move under the push-and-pull action of handle 10；With
The side of fuel tank 1 of the correspondence position of handle 10 sets safety switch 9, and safety switch 9 is triggered after being moved by handle 10, and handle 10 is moved to
Body 8 is turned on during 9 trigger position of safety switch and is inserted between taper plug 7 and oil suction base 11 makes the inner space of fuel tank 1 and oil suction
Pipe 12 connects.
The flexible plug mechanism is made up of spiral cover 2, guide sleeve 4, guide pillar 5, taper plug 7 and spring 6；Guide sleeve 4 is logical
Cross spiral cover 2 to be fixed in fuel tank 1, sealed between spiral cover 2 and fuel tank 1 by ring flange 3；Taper plug 7 is fixed with guide pillar 5 to be connected
Connect, the top of guide pillar 5 is sleeved in guide sleeve 4 and is slidably connected with guide sleeve 4, and spring 6 is set between guide sleeve 4 and taper plug 7.
The cone end of the taper plug 7 sets transition arc.
