Description

OIL CAP ASSEMBLY OF AN OIL TANK
BACKGROUND OF THE INVENTION
1. Field of the Invention:
The present invention relates to oil tank technology and more particularly, to an oil cap assembly of an oil tank that assures tight engagement between the cap and the oil hole, preventing oil leakage.
2. Description of the Related Art:
A conventional metal oil tank for motor vehicle generally, as shown in FIGS. 1 and 2, comprises a pair of lugs 101 (only one lug is seen in the drawings) arranged at two sides of the oil hole 10, and a cap assembly, which is comprised of an oil cap 20 and a locking lever 30. The oil cap 20 is hinged to the peripheral wall of the oil hole 10 (see FIG. 3), and can be opened from the oil hole 10 or capped on the oil hole 10 to close the passage. The locking lever 30 has an inner end 301, and outer end 302, and a pair of legs 303. The inner end 301 of the locking lever 30 is pivoted to the top side of the oil cap 20.
When the user operate the outer end 302 to bias the locking lever 30 downwards, the legs 303 are forced into lugs 101, locking the oil cap 20 to the oil hole 10 in the close position.
FIGS. 4 and 5 show another structure of oil cap assembly according to the prior art. This design is substantially similar to the design shown in FIGS. 13 with the exception that the oil cap 20 has a transverse barrel 201 at the top, and the locking lever 30 has two through holes 304 aligned at two opposite lateral sides corresponding to the transverse barrel 201.
When the locking lever 30 is turned to the locking position, a pin 40 is inserted through the through holes 304 and the barrel 201, prohibiting biasing of the locking lever 30 relative to the oil cap 20. Therefore, the locking lever 30 can be biased to unlock the oil cap 20 only after the pin 40 has been removed from the through holes 304 of the locking lever 30 and the barrel 201 of the cap 20.
The aforesaid two prior art designs are still not
satisfactory in function. When the oil tank is kept in vertical after locking of the oil cap assembly, the oil cap assembly prohibits oil leakage. However, when the oil tank is overturned, the cap assembly cannot stop oil leakage. Therefore, an improvement in this regard is necessary.
SUMMARY OF THE INVENTION
The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide an oil cap assembly for oil tank, which holds down the locking lever and imparts a downward pressure to the oil cap to enhance the tightness of the engagement between the oil cap and the oil hole, avoiding oil leakage upon accidental overturn of the oil tank.
To achieve this and other objects of the present invention, the oil cap assembly comprises an oil cap hinged to an oil tank for closing the oil hole of the oil tank, a locking lever pivoted to the oil cap for locking the oil cap in the close position, and a holding down device for fastening to the free end of the locking lever to hold down the locking lever in the locking position and to impart a downward pressure to the oil cap, thereby enhancing the tightness of the engagement between the oil cap and the oil hole and avoiding accidental oil leakage.
Further, the holding down device comprises a mounting plate affixed to the oil tank, a horizontal rod pivotally coupled to the mounting plate, and a threaded connection rod perpendicularly extending from the horizontal rod and attachable to the outer end of the locking lever when the locking lever is in the locking position, and a locknut threaded onto the threaded connection rod and pressed on the outer end of the locking lever to impart a downward pressure to the locking lever and the oil cap.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 6 and 7, an oil cap assembly in accordance with the present invention is shown installed in the body 51 of an oil tank 5 and adapted for sealing the oil hole 1 of the oil tank 5. The body 51 of the oil tank 5 has two lugs 11 arranged at two sides of the oil hole 1. The oil cap assembly is comprised of an oil cap 2, a locking lever 3, and a holding down device 4.
The oil cap 2 is hinged to the body 51 of the oil tank 5 adjacent to the oil hole 1 and adapted to closing the oil hole 1, having a gasket pad (not shown) on the inside.
The locking lever 3 has an inner end 31, an outer end 32, and two legs 33. The inner end 31 is pivoted to the top side of the oil cap 2. The outer end 32 is configured for grasping by the user to bias the locking lever 3 relative to the oil tank 5. When the locking lever 3 is biased downwards, the legs 33 are respectively forced into the legs 11, thereby locking the oil cap
S
2 in the close position. Further, the outer end 32 of the locking lever 3 has a notch 321 (see FIG. 7).
Referring to FIG. 8, the holding down device 4 comprises a mounting plate 44 affixed to the body 51 of the oil tank 5, a horizontal rod 43 pivotally coupled to the mounting plate 44, a connection rod 41 fixedly and perpendicularly extending from a middle part of the horizontal rod 43 and having an outer thread 411 extending around the periphery, and a locknut 42 for threading onto the outer thread 411 of the connection rod 41. According to the embodiment shown in FIG. 8, the outer thread 411 extends around the periphery of the upper part of the connection rod 41. Alternatively, as shown in FIG. 14, the connection rod 41 can be made having the outer thread 411 extending around the periphery over the whole length.
Referring to FIGS. 9 and 10 and FIGS. 7 and 8 again, when the locking lever 3 is turned downwards to the locking position, the connection rod 41 is turned with the horizontal rod 43 relative to the mounting plate 44 and forced into the notch 321 of the outer end 32 of the locking lever 3 (see FIGS. 7 and 9), and then the locknut 42 is threaded onto the outer thread 411 of the connection rod 41 and pressed on the outer end 32 of the locking lever 3 to impart a downward pressure to the locking lever 3 (see FIG. 10), tightening the engagement between the oil cap 2 and the oil hole 1.
Therefore, when the locking lever 3 is turned to the locking position to force the legs 33 into the lugs 111, the oil cap 2 is locked to the oil hole 1. At this time, the user can thread the locknut 42 onto the outer thread 411 of the connection rod 41 to impart a downward pressure to the locking lever 3, tightening the engagement between the oil cap 2 and the oil hole 1. When wishing to open the oil cap 2, unfasten the locknut 42 from the connection rod 41 (see FIG. 11), and then turn the connection rod 41 away from the locking lever 3 (see FIG. 12), and then turn the locking lever 3 upwards to unlock the oil cap 2 for allowing the oil cap 2 to be opened from the oil hole 1 (see FIGS. 13 and 14).
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention.
