Abstract
The utility model provides the anti-lost chain of a kind of Pneumatic extinguisher fuel tank cap, and comprise fuel tank lid, fuel tank lid is provided with fixed hole, and fixed hole is provided with blanking cover, and blanking cover is provided with the fixed end of band self-locking dop.Between fuel tank lid and blanking cover, be provided with anti-lost chain, anti-lost chain one end is provided with air inlet annular groove, air inlet annular groove is provided with through hole, through hole is fixed wtih blanking cover, and the other end of anti-lost chain arranges snap ring, and the maximum inner diameter of snap ring is consistent with fuel tank mouth effective diameter of thread.When the anti-lost chain of this Pneumatic extinguisher fuel tank cap avoids oiling, fuel tank cap drops to the phenomenon in thick grass, has saved the time of refueling.
Description
Technical field
The utility model relates to a kind of Pneumatic extinguisher parts, more particularly relates to the anti-lost chain of a kind of Pneumatic extinguisher fuel tank cap.
Background technique
The main Fire extinguisher of the current still forest extinguishing of the Pneumatic extinguisher as forest-fire prevention equipment, in use often needs to supplement fuel oil in fuel tank, needs fuel tank cap to screw down to be placed on one side, fuel tank cap of screwing on again after adding oil when interpolation fuel oil.Due at fire-extinguishing location, weeds, fallen leaves etc. are a lot, and frequent produced problem is after adding oil, and fuel tank cap drops in thick grass and is not easy to find, and have impact on the normal use of machinery, have seriously delayed flame extinction time.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model provides the anti-lost chain of a kind of Pneumatic extinguisher fuel tank cap.
The utility model is achieved through the following technical solutions: the anti-lost chain of a kind of Pneumatic extinguisher fuel tank cap, comprise fuel tank lid, described fuel tank lid is provided with fixed hole, and fixed hole is provided with blanking cover, described blanking cover is provided with fixed end, and fixed end is provided with self-locking dop; Be provided with anti-lost chain between fuel tank lid and blanking cover, described anti-lost chain one end is provided with air inlet annular groove, and air inlet annular groove is provided with through hole, through hole is fixed wtih blanking cover, the other end of anti-lost chain arranges snap ring, and the maximum inner diameter of snap ring is consistent with fuel tank mouth effective diameter of thread.
In such scheme, for the ease of installing anti-lost chain, the snap ring of described anti-lost chain is provided with slotted eye.
In such scheme, in order to fixing anti-lost chain connects with fuel tank lid, the fixed end of described blanking cover is arranged
There is self-locking dop.
A kind of anti-lost chain of the utility model compared with prior art, has following beneficial effect:
Owing to being provided with anti-lost chain in fuel tank cap, when refueling in mechanical fuel tank, the fuel tank cap backed out can hang over the side of fuel tank, avoids fuel tank cap and to drop phenomenon, has saved the time of refueling.
Accompanying drawing explanation
Fig. 1 is the structural representation of the anti-lost chain of the utility model fuel tank cap;
Fig. 2 is the plan view of part 2 in Fig. 1.
In figure: 1. fuel tank lid, 2. anti-lost chain, 3. blanking cover, 4. through hole, 5. self-locking dop, 6. fixed hole, 7. snap ring, 8. slotted eye, 9. air inlet annular groove, 10, fixed end.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the anti-lost chain of the utility model Pneumatic extinguisher fuel tank cap is further described:
Fig. 1 is the structural representation of the anti-lost chain of the utility model Pneumatic extinguisher fuel tank cap.In figure, the anti-lost chain of this Pneumatic extinguisher fuel tank cap, comprises the fixed hole 6 on fuel tank lid 1 and fuel tank lid 1.Fixed hole 6 is provided with blanking cover 3, one end of blanking cover 3 is provided with self-locking dop 5.Between fuel tank lid 1 and blanking cover 3, be provided with anti-lost chain 2, anti-lost chain 2 one end is provided with air inlet annular groove 9, air inlet annular groove 9 is provided with through hole 4, through hole 4 is fixed wtih blanking cover 3.The other end of anti-lost chain 2 arranges snap ring 7, and the maximum inner diameter of snap ring 7 is consistent with fuel tank mouth effective diameter of thread.For the ease of installing anti-lost chain 2, the snap ring 7 of anti-lost chain 2 is provided with slotted eye 8.
During use, placed by blanking cover 3 on the through hole 4 of the air inlet annular groove 9 of anti-lost chain 2, the self-locking dop 5 of the fixed end of blanking cover 3 puts into the fixed hole 6 of fuel tank lid 1.The other end snap ring 7 of anti-lost chain 2 is enclosed within fuel tank mouth outside thread, fuel tank lid 1 of then screwing on.When adding fuel oil, backing out fuel tank lid 1, because snap ring 7 is enclosed within fuel tank mouth outside thread, fuel tank lid 1 can not being fallen, avoid fuel tank lid 1 and drop, saved the time of refueling.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when the method and technology contents that can utilize above-mentioned announcement are made a little change or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, still belong in the scope of technical solutions of the utility model.
