Description
Technical field
The present invention relates to the fuel tank cap of Work machine such as hydraulic shovel, especially prevent to the inside anti-locking mechanism of immersion of immersion of fuel.
Background technique
Fig. 4 is the side view of previously known hydraulic shovel, symbol 1 expression lower running body, symbol 2 expression upper rotating body, symbol 3 expression shear legs, symbol 4 expression cantilevers, symbol 5 expression scraper bowls, symbol 6 expression operator cabins, symbol 7 expression counterweights, symbol 8 expression engine compartments, symbol 9 expression fuel tanks.From this figure as can be known, in Work machines such as hydraulic shovel, fuel tank 9 is configured to be exposed to outside state.
On the top board 9a of fuel tank 9, generally perpendicularly be provided with fuel inlet 10 cylindraceous, on its opening portion, releasably be equipped with and be used to prevent from the volatilization of the fuel of fuel tank 9 and the fuel tank cap 11 that foreign matter is invaded in fuel tank 9.
As shown in Figure 5, fuel tank cap 11 comprises: releasably be installed in the lid main body 12 on the fuel inlet 10; Be arranged at the lock core box 13 that covers on the main body 12; The lock core 14 that in lock core box 13, is provided with; The cap assembly 15 of the lock core of installing at the outer surface of lock core box 13 14; And the sealed member 16 of the waterproof between sealing lock core 14 and the cap assembly 15.
As shown in Figure 6, cap assembly 15 is that the center can be along the outer surface rotation of lock core box 13 with the pin 15a to back side lateral process setting, by rotary cover parts 15 up to the center of the center of cap assembly 15 and lock core box 13 consistent location almost, available covers parts 15 cover the space A (with reference to Fig. 5) between the outer surface of the internal surface of lock core box 13 and lock core 14, can prevent to soak in fuel tank 9 from this space A.In addition, insert the position that mouthful 14a exposes by being center rotary cover parts 15 with pin 15a up to the key that is located on the lock core 14, then can carry out key inserts the unblanking and locking and take out fuel tank caps 11 of insertion, lock core 14 from mouthful 14a to key from fuel inlet 10.
The fuel tank cap 11 of above-mentioned original structure is owing to possess the cap assembly 15 that is used for covering lock core 14 on lock core box 13, if thereby cap assembly 15 words of correctly closing with respect to lock core box 13 and lock core 14, just can prevent to prevent the deterioration of fuel and the corrosion of fuel tank 9 from the immersion of space A in fuel tank 9 between the outer surface of the internal surface of lock core box 13 and lock core 14.
Yet, because cap assembly 15 must be closed with manual unlocking, thereby, if having forgotten, the worker closes cap assembly 15, or operation trouble and when deliberately not closing cap assembly 15, sparge water when rainwater and carwash soaks in fuel tank 9 from the space A between the outer surface of the internal surface of lock core box 13 and lock core 14, can not prevent the deterioration of fuel and the corrosion of fuel tank 9.
Summary of the invention
The present invention proposes for the shortcoming that solves this original technology, even its objective is the fuel tank cap that the Work machine of the immersion in fuel tank also can be provided when providing a kind of cap assembly correctly not closed.
The present invention proposes following technological scheme in order to solve above-mentioned problem, first scheme of the present invention, a kind of fuel tank cap of Work machine, possess lid main body on the fuel inlet that releasably is installed in fuel tank, be arranged on lock core box on this lid main body,, the lock core of in this lock core box, setting and the cover of closing of opening that on this lock core box, covers this lock core, adopt between the outer surface of the internal surface of this lock core box and this lock core the structure of waterproof with sealed member be set.
Adopt the words of this structure, even the occasion of correctly not closed at cap assembly, owing to prevented immersion in fuel tank by the waterproof that between the outer surface of the internal surface of lock core box and lock core, is provided with sealed member, thereby can prevent the deterioration of fuel and the corrosion of fuel tank.
In addition, alternative plan of the present invention, in the fuel tank cap of the structure of described first scheme, adopting described waterproof sealed member is the structure of O shape circle (O-ring).
Because O shape circle (O-ring) is a staple, obtains necessary size easily, thereby can implement to possess the fuel tank cap of waterproof at an easy rate with sealed member.
Adopt this structure, owing to can intactly utilize original fuel tank cap, thus can implement to possess the fuel tank cap of waterproof at an easy rate with sealed member.In addition, owing to can prevent space A immersion between the outer surface of the internal surface of lock core box and lock core more reliably by cap assembly, thus can further improve the water proofing property of fuel tank cap.
The present invention has following effect.
Adopt words of the present invention, owing between the outer surface of the internal surface of lock core box and lock core, the waterproof sealed member is set, even the occasion of correctly not closed at cap assembly, also can prevent between the outer surface of the internal surface of lock core box and lock core, in fuel tank, to soak, prevent the deterioration of fuel and the corrosion of fuel tank.

Embodiment
Below, based on Fig. 1 to Fig. 3 the mode of execution of the fuel tank cap of Work machine of the present invention is described.Fig. 1 is the sectional view of the fuel tank cap of relevant mode of execution, and Fig. 2 is the B portion amplification view of Fig. 1, and Fig. 3 is the stereogram of the waterproof of relevant mode of execution with sealed member.
As shown in Figure 1, the fuel tank cap 11 of the Work machine that this is routine fuel tank cap with the Work machine of Fig. 5 and original example shown in Figure 6 on overall structure is identical, have main body covered 12, at the lock core box 13 that is provided with on the lid main body 12, the lock core 14 that lock core box 13 in, is provided with, be rotatably installed in the waterproof sealed member 16 between cap assembly 15, sealing lock core 14 and the cap assembly 15 of lock core 14 of outer surface of lock core box 13.
This routine fuel tank cap 11 is with the difference of the fuel tank cap of original example, is provided with waterproof with sealed member 21 between the outer surface of the internal surface of lock core box 13 and lock core 14.Can use the rubber elastomer of O shape circle (O-ring) shown in Figure 3 or O shape circle ring-type in addition etc. with sealed member 21 as waterproof.Because O shape circle is a staple, is easy to obtain necessary size, thereby be particularly suitable for implementing at an easy rate to possess the fuel tank cap of waterproof with sealed member.As shown in Figures 1 and 2, waterproof with sealed member 21 folding and unfoldings in being formed at the sealing folding and unfolding recess 22 of lock core box 13 internal surfaces.Like this, can stably keep waterproof with sealed member 21, can prevent the space A immersion between the outer surface of the internal surface of lock core box 13 and lock core 14.Also have, waterproof is provided with the position so long as the words in the scope of the internal surface of lock core box 13 with sealed member 21, just have no particular limits, but consider be easy to carry out waterproof with sealed member 21 operation is set and water is not trapped in the A of space, prolong the wear life of waterproof, then be arranged on position as far as possible near the outside (cap assembly 15 sides) with sealed member 21.
Because the fuel tank cap 11 of this routine Work machine is provided with waterproof usefulness sealed members 21 such as O shape circle between the outer surface of the internal surface of lock core box 13 and lock core 14, even the occasion of correctly not closed at cap assembly 15, also can prevent from fuel tank, to soak, prevent the deterioration of fuel and the corrosion of fuel tank from space A.In addition, owing on lock core box 13, possess cap assembly 15, thus closing space A by operation cap assembly 15, can prevent from more reliably in fuel tank, to soak from space A.
