Specific embodiment
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control attached drawing is described in detail
A specific embodiment of the invention.
As shown in Figure 1, 2, the refueling nozzle of one embodiment of the invention, including gun body 10 and flexible oil filling pipe 20, add
Oil pipe 20 is connected in gun body 10, and is connected to the inner cavity of gun body 10, and fuel oil flows to oil filling pipe 20 from gun body 10.
Wherein, as shown in Figure 2,4, oil filling pipe 20 includes the oiling tube body 21 passed through for fuel oil.Oiling tube body 21 include with
The linkage section 211 of the connection of fuel oil gun body 10 is inserted into the inserting paragraph 213 of oiling container and is connected to linkage section 211 and insertion
Bendable tune 212 between section 213.The bending of entire oiling tube body 21 is realized by the bending of bendable tune 212, is adjusted and is added
The direction of the inserting paragraph 213 of oil pipe body 21 facilitates insertion oiling container to refuel.
Oiling tube body 21 is structure as a whole.Preferably, the bendable tune 212 of oiling tube body 21 is wavy metal pipeline section.
It is equipped with oil discharge passage 214 and self-styled channel 215 in oiling tube body 21, oil discharge passage 214 and self-styled channel 215 are along adding
Oil pipe body 21 is axially extending and is isolated.Oil discharge passage 214 passes through for fuel oil to enter oiling container.
Specifically, oil discharge passage 214 penetrates through oiling tube body 21, i.e., extends to inserting paragraph 213 from linkage section 211, and perforation connects
Connect the import of section 211 and the outlet of inserting paragraph 213.Self-styled channel 215 ends in inserting paragraph 213, extends to from linkage section 211 slotting
Enter section 213, penetrates through the import of linkage section 211, the outlet without penetrating through inserting paragraph 213.Also, the side wall of inserting paragraph 213 is equipped with
Radial perforation is to the pore self-sealing 216 in self-styled channel 215, and when refueling, pore self-sealing 216 can be connected to inside oiling container.Work as oiling
When container fills it up with oil, oil liquid blocks pore self-sealing 216, and refueling nozzle then jumps rifle and stops refueling.
Further, 213 exit of inserting paragraph of oiling tube body 21 is additionally provided with drip-proof check-valves 22.The check-valves 22
It is located at the outside in self-styled channel 215 on oiling tube body 21.Check-valves 22 also prevents oil liquid from flowing back, and refueling nozzle is avoided frequently to jump
Rifle.
As an implementation, check-valves 22 may include pedestal 221, telescopic elastic component 222 and pass through elasticity
Part 222 is connected to the valve block 223 on pedestal 221.Valve block 223 is arranged in oil discharge passage 214, by valve block 223 to close or
The on-off of oil discharge passage 214 is controlled far from the movement of 221 direction of pedestal.Check-valves 22 can be mounted on oil filling pipe by pedestal 221
In the outlet of inserting paragraph 213 of body 21.The periphery of pedestal 221 can be equipped with screw thread and the inner circumferential of inserting paragraph 213 cooperates, or be equipped with step
It is fastened with the outlet end of inserting paragraph 213.
The end face opposite with valve block 223 of pedestal 221 is additionally provided with through-hole 224, leads to when oil discharge passage 214 is open with fuel-displaced
Road 214 is connected.
Further, sealed step 217 is equipped in oil discharge passage 214；Valve block 223 is under the pushing effect of elastic component 222
Sealed step 217 is compressed, oil discharge passage 214 is closed.
The sealed step 217 is the ring-shaped step being arranged on 213 inner wall of inserting paragraph, and the hole in the middle part of ring-shaped step is less than valve
When valve block 223 is pressed in sealed step 217, the hole in the middle part of ring-shaped step is closed, realizes the envelope of oil discharge passage 214 for piece 223
It closes.
When oiling, fuel oil flow to oil filling pipe 20 from gun body 10, flow to valve block 223 in the oil discharge passage 214 of oiling tube body 21,
Valve block 223 is pushed, valve block 223 is made to leave sealed step 217 to close to the movement of 221 direction of pedestal, open oil discharge passage 214,
Fuel oil is flowed out by through-hole 224 on oil discharge passage 214 and pedestal 221.Valve block 223 is flowed to when there are fuel flow returns to pass through through-hole 224
When, valve block 223 is pressed in sealed step 217 by pushing, is closed oil discharge passage 214, is prevented fuel oil from entering oil discharge passage 214.
In non-refuelling, valve block 223 is pushed by 222 restoring force of elastic component and is pressed in sealed step 217, closes oil discharge passage 214,
21 oil dripping of oiling tube body is prevented, to play the role of drip-proof.
Further, as shown in Fig. 1-3 and Fig. 5, which further includes the scalable set being set in outside oiling tube body 21
Pipe 30.It with reference to Fig. 2,4, remains static in refueling nozzle, the inserting paragraph 213 of oiling tube body 21 is located in telescopic sleeve pipe 30；
With reference to Fig. 3,4, it is in fueling state in refueling nozzle, telescopic sleeve pipe 30 is compressed to 10 direction of gun body, the insertion of oiling tube body 21
Section 213 is stretched out from telescopic sleeve pipe 30.
