It has solved among the prior art machine oil filler hole not convenient to produce processing, and the leakproofness is poor, pulls out and inserts inconvenient problem. This machine oil filler cap structure, including the lid, the lid top is provided with the lid and emits, the lid emits and has the buckling towards the lid other end, and the lid lower extreme is provided with the thread, is provided with the sealing washer on the lid between thread and the lid emits, be provided with the cavity through lid lower extreme and outside UNICOM in the lid. The utility model discloses a lid design that inside has the cavity and has the bending type makes the structure be convenient for draw the material and guarantees that the wall thickness is even, makes things convenient for the demolding, can be with the oil flap formula of being one-tenth again, simple structure, and the processing of being convenient for does benefit to sealedly.

Description

Engine oil filler cap structure

Technical Field

The utility model belongs to the technical field of auto-parts, a oil filler hole part is related to, especially an engine oil filler cap structure.

Background

The machine oil filler cap is used for sealing the automobile oil filler, but the current machine oil filler cap has a complex structure, is inconvenient to produce and process, has poor sealing performance and is inconvenient to pull and insert.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an above-mentioned problem to prior art exists has provided an engine oil filler cap structure, and engine oil filler cap simple structure, the production and processing of being convenient for improves sealing performance, conveniently pulls out and inserts.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides an engine oil filler cap structure, includes the lid, the lid top is provided with the lid and emits, the lid emits and has the buckling towards the lid other end, and the lid lower extreme is provided with the spiral shell and detains, is provided with the sealing washer on the lid between spiral shell knot and the lid emits, be provided with the cavity through lid lower extreme and outside UNICOM in the lid. This structure is convenient for draw the material and guarantees that the wall thickness is even, makes things convenient for the demolding, can be with the oil flap formula as an organic whole again, simple structure, the processing of being convenient for.

In the above-mentioned oil filler cap structure, the sealing washer is the elasticity sealing washer that has the cavity, the cavity of sealing washer with the cavity of lid passes through the air flue UNICOM for the sealing washer can be passed to the pressure in the oil port, and the sealing washer rises when pressure is big, and is sealed tighter.

In the above oil filler cap structure, the cavity of the cap body is a cylindrical cavity, a piston is arranged in the cavity, and a magnet is arranged on the piston, so that the attraction or repulsion of the piston is realized by placing another magnet on the cap, thereby controlling the pressure in the cavity and controlling the size of the sealing ring.

Compared with the prior art, the oil filler cap structure of the engine has the following advantages:

the utility model discloses a lid design that inside has the cavity and has the bending type makes the structure be convenient for draw the material and guarantees that the wall thickness is even, makes things convenient for the demolding, can be with the oil flap formula of being one-tenth again, simple structure, and the processing of being convenient for does benefit to sealedly.

In the figure, a cover body 1, a cover cap 2, a screw thread 3, a sealing ring 4, an air channel 5, a piston 6, a magnet 7, an opening 8, a push rod 9, a pressure rod 10, a connecting rod 11, an oil port 12 and a pressure pad 13.

Detailed Description

The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

Example one

As shown in fig. 1, an engine oil filler cap structure, including lid 1, the lid top is provided with lid cap 2, the lid cap has the buckling towards the lid other end, and the lid lower extreme is provided with the spiral shell and detains 3, is provided with sealing washer 4 on the lid between spiral shell and the lid cap, be provided with the cavity through lid lower extreme and outside UNICOM in the lid. This structure is convenient for draw the material and guarantees that the wall thickness is even, makes things convenient for the demolding, can be with the oil flap formula as an organic whole again, simple structure, the processing of being convenient for.

Example two

As shown in fig. 2, the sealing ring is an elastic sealing ring with a cavity, and the cavity of the sealing ring is communicated with the cavity of the cover body through an air passage 5, so that the pressure in the oil port can be transmitted to the sealing ring, and the sealing ring expands when the pressure is high, thereby achieving tighter sealing.

The cavity of lid is cylindrical cavity, be provided with piston 6 in the cavity, be provided with magnet 7 on the piston to thereby place another magnet through covering and realize the size of the pressure control sealing washer in the attraction or the repulsion control cavity to the piston.

Although some terms are used more herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed in a manner that is inconsistent with the spirit of the invention.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
