Abstract
The utility model relates to a gear cover oiling hole device which comprises a buckle cover and a refueling neck, wherein, one side of the buckle cover is hinged with the outer wall of an entrance of the refueling neck, and the other side of the buckle cover is locked on the outer wall of the refueling neck through a locking mechanism; a sealing element is arranged between the buckle cover and a top mouth of the refueling neck; the sealing element is composed of a rubber sealing pad which is clamped on the inner wall of the buckle cover in an axial sliding mode, and a spring which is axially arranged in an interstice between the rubber sealing pad and the buckle cover. The sealing element which is composed of the spring and the rubber sealing pad is additionally installed between the buckle cover and the entrance of the refueling neck, so the rubber sealing pad can be tightly pressed at the entrance of the refueling neck when the buckle cover is locked tightly; thus, the oil leakage phenomenon is avoided. The bottom surface of the rubber packing pad is provided with a conical wedge head which is buckled on an expanding mouth, and the expanding mouth is correspondingly arranged at the conical surface of the entrance of the refueling neck; thus, the seal contacting surface can be enlarged, and the sealing property can be strengthened further. The spring of the utility model is designed to a tower-shaped compressing spring which can cause the axial size of the inner part of the buckle cover to be reduced; thus, the whole structure of the utility model can become more compact and smarter.
Description
Technical field
The utility model relates to a kind of tank filler sleeve device, relates in particular to a kind of gear cover tank filler sleeve device that is made of the buckle closure and the neck that refuels.
Background technique
Existing gear cover tank filler sleeve device is made of the buckle closure and the neck that refuels, one side of buckle closure is hinged together by the outer wall of hinge with the oiling ingress of oiling neck, the opposite side of buckle closure is locked in by locking mechanism and refuels the opposite side of neck ingress outer wall, and the Sealing of making by malthoid between the inlet of buckle closure and oiling neck seals.The problem of this device is: malthoid impression can occur in long-term using process, also can cause seal clearance to increase, and seal action can weaken gradually, and the seepage phenomenon is day by day serious, has influence on the normal use of gear cover.
The model utility content
At the problems referred to above, the purpose of this utility model is to provide a kind of gear cover tank filler sleeve device, to solve the leakage problems of gear cover tank filler sleeve device.
For achieving the above object, the technical solution of the utility model is to adopt a kind of gear cover tank filler sleeve device, comprise buckle closure, oiling neck, one side of buckle closure is hinged together with the outer wall of oiling neck ingress, the opposite side of buckle closure is locked on the outer wall of oiling neck by locking mechanism, buckle closure and refuel and to be provided with Sealing between the top mouth of neck, described Sealing are installed on the spring of axially installing in rubber gasket on the buckle closure inwall and the gap between rubber gasket and the buckle closure and constitute by endwisely slipping.
Described spring is the turriform pressure spring.
The bottom surface of described rubber gasket is provided with a taper type wedge head, and the internal orifice of oiling neck is provided with a conical surface enlarging, and coincideing between two conical surfaces is sealed and matched.
Owing to add the Sealing that constitutes by spring and rubber gasket in buckle closure and oiling neck ingress, make that rubber gasket was pressed on the oiling neck inlet when buckle closure was locked, stopped the generation of seepage oil situation.Be buckled in the corresponding conical surface enlarging that is provided with in oiling neck ingress at the cone wedge head that is provided with on the rubber gasket bottom surface, can enlarge sealing contact surface, further the enhanced leaktightness performance.Spring is designed to the turriform compressing spring, and the inner shaft that can make buckle closure makes the structure of whole device compact more dexterous to size decreases.
