Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of motor car engine cap.
Background technique
At present, the cap that motor car engine is used exists operates effort and inconvenient shortcoming, and the machine oil pipe filler cap that common engine is used adopts a steel sheet spring and an inclined-plane to seal oil filler, when this structure is unclamped after tightening again, relatively requires great effort; In addition, there is poorly sealed shortcoming in said structure, and this is that afterwards sealing contact surface is little because common machine oil pipe filler cap is tightened, and some particulate matters are easy to from then on poorly sealed place and get into motor, bring harm to motor.
Existing Chinese patent document discloses a kind of engine motor oil pipe filler cap [patent No.: ZL02255622.2]; Comprise cover plate, operating grip, block rubber and base plate, a cavity is arranged at the bottom of cover plate, is embedded with a columniform block rubber in the cavity; The block rubber upper part diameter equals the diameter of cover plate cavity; And be embedded in the cavity, the diameter of block rubber bottom is slightly less than upper part diameter, equals the internal diameter of oil filling pipe; Base plate is positioned at the below of block rubber, and diameter is slightly less than the diameter of block rubber bottom, and the center is porose, and internal thread is arranged, and matches with the outside thread of operating grip, and for better sealing, the bottom of block rubber has annular groove.Though this model utility has solved the not good problem of sealing effect, it adds machine oil lid and has handle, and is made up of three and above component, and structure is complicated, and cost of production is higher.
Existing Chinese patent document discloses a kind of motor cap sealing configuration [application number: 201020218275.X], comprises that cap, oil filler cover through the seal ring of mounting groove setting and the valve chamber cover oil filler of adaptive cap; It is characterized in that: described cap bottom has been provided with the oblique slot of interconnect function, and in the end notch that is communicated with oblique slot is set; The boss of adaptive described oblique slot is set on the described valve chamber cover oil filler inwall; During sealing, the boss on the described valve chamber cover mouth inwall screws in the described oblique slot through notch and connects.There is baroque problem equally in this model utility, and it also will design the valve chamber cover oil filler adaptive with it on the basis of design cap, and cost of production is higher.
Summary of the invention
There are the problems referred to above in the utility model to existing technology, has proposed a kind of motor car engine cap, and this motor car engine cap can reduce production costs and can reach reliable sealing effect.
The utility model is realized through following technical proposal: a kind of motor car engine cap; The lid that comprises integral structure; The upper end portion of said lid has the flange of outside protrusion; The lower surface of described flange offers the mounting groove of annular, in mounting groove, is provided with sealing gasket, and described sealing gasket exceeds mounting groove.
In above-mentioned motor car engine cap, the underpart outer side surface of said lid is a worm structure.
This cap comprises the lid and the sealing gasket of integral structure; Its sealing gasket is anchored on the mounting groove of lid; Its sealing gasket exceeds mounting groove one segment distance; When this cap was screwed in oil filler, its part that exceeds mounting groove combines with the worm structure of lid underpart outer side surface, and was more reliable to the sealing effect of oil filler.
In above-mentioned motor car engine cap, the external diameter of said sealing gasket is greater than the external diameter of mounting groove.Such design makes sealing gasket and mounting groove form interference fit, in conjunction with tight, and difficult drop-off, simple in structure.
In above-mentioned motor car engine cap, the outer periphery of said flange is concavo-convex alternate structure.Loading and unloading in its concavo-convex alternate structure process easy to use and can play anti-skidding effect.
In above-mentioned motor car engine cap, the lower surface of said flange is evenly distributed with circular groove, and described circular groove is positioned at the projection of above-mentioned concavo-convex alternate structure, and is positioned at the outside of mounting groove.Its equally distributed circular groove can alleviate the overall weight of cap.
In above-mentioned motor car engine cap, described lid portion inside is a cavity structure, and its cavity internal surface is evenly distributed with stiffening rib.This stiffening rib can overcome the shortcoming of cavity worm structure insufficient strength, makes in use more reliable.
In above-mentioned motor car engine cap, the end face of the upper end portion of said lid is provided with sign.This identifies the identification in the process easy to use.
Compared with prior art, this motor car engine cap has the following advantages:
1, sealing gasket exceeds mounting groove one segment distance in the utility model; Its part that exceeds mounting groove combines with the worm structure of lid underpart outer side surface, makes more reliably to the sealing effect of oil filler, and the used material category of this model utility is few in addition; Be beneficial to batch process, cost is low.
2, the external diameter of sealing gasket makes sealing gasket and mounting groove form interference fit greater than the external diameter of lid mounting groove in the utility model, in conjunction with tight, and difficult drop-off, simple in structure.
