Abstract
Disclosed is a visible valve cover, comprising a valve cover main body and a visible mirror. The middle part of the valve cover main body is provided with a circular through hole with boss, and is in an interference fit with the visible mirror in the through hole. The visible mirror are assembled by an inner frame made up of metal circles, a sealing ring, a high strength glass mirror and a fluoroelastomer sealer. The outer edge of the valve cover main body is provided with a tightening and loosing mechanism in the shape of cross protrusion or cross groove. The major advantages of the utility model are that the scheme is concrete, the conception is ingenious, the design is reasonable, the producing is convenient and the practicability is strong. Especially by the ingeniously designed visible mirror, the working condition of the valve actuating mechanism of engine and the lubricating condition of engine oil can be seen. The utility model is convenient to check and maintain, and is suitable for volume-produce.
Description
Technical field the utility model relates to the improvement technology of motorcycle engine structure, is specifically related to a kind of visual valve cap that can see engine interior distribution device state.
In the background technique prior art, be furnished with valve cap on the motorcycle engine cylinder head usually, its structure is the threaded cap of band hexagonal nuts, and main effect is the convenient valve clearance of regulating.Be metallic material and make, therefore can't observe the internal mechanical motion conditions of motor, be not easy to inspection and maintenance.Chinese patent 02273328.0 " transparent four stroke engine valve inspection cover " discloses a kind of valve inspection cover of being made by transparent material and non-transparent material, only is a kind of thinking but it provides.Its technological scheme lacks feasibility, and first kind of mode is to make valve cap by transparent material; In the heart, transparent valve inspection cover is made in combination to second way usefulness transparent material " edge " in non-transparent material.The former makes obvious shortage exploitativeness for transparent material, does not still have a kind of inexpensive material that can bear high-temperature pressure-proof power like this at least at present both at home and abroad; The latter just proposes transparent material " edge " is combined into transparent flap on non-transparent material synoptically, though also mention in the specification and can put the O RunddichtringO or sealer is installed in it on motor, does not form complete, technological scheme clearly.Therefore, one of ordinary skill in the art can not realize its goal of the invention by the content of specification.And, the center of top of existing valve cap is less and protruding hexagon nut shape, and this patent is located at peep hole among original hexagon nut, and inevitable masking aperture is less, be not easy to clear view, even the hole is amplified also and need be tightened/pine with the higher Allen wrench of price.Therefore, also do not see enforcement up to this technology nowadays, product is also failed listing.Many manufacturers also urgently wish to develop the observation mirror that can conveniently observe engine interior, establish the hole at the valve cap top and be set with the glass of seal rubber sleeve, in the hope of reaching the purpose of being convenient to observe, but because seal rubber sleeve or rubber gasket rigidity are poor, there are defectives such as poorly sealed, finally also are difficult to realize.
The deficiency that summary of the invention exists at above-mentioned prior art, the purpose of this utility model is to provide that a kind of technology is reliable, scheme is feasible, can directly see engine interior distribution device state and oil lubricating situation and not need the higher Allen wrench of price to get final product the visual valve cap of degree of tightness.
The purpose of this utility model is achieved in that visual valve cap, form by valve cap body and visible mirror, valve cap body middle part is provided with the manhole of boss, interference fit visible mirror in the through hole, visible mirror makes inner frame by the metal circle and seal ring, high strength glass mirror and fluorine rubber sealing layer combine.Cross projection or cross groove degree of tightness mechanism are established in valve cap body outer.
Valve cap body outer also can be hexagonal configuration degree of tightness mechanism.
Major advantage of the present utility model is: scheme is reliable, be skillfully constructed, reasonable in design, easy to make, practical, especially by designing visible mirror cleverly, visible mirror is by the seal ring support of band skeleton, can on lid, open than large through-hole, realization can be seen engine valve actuating mechanism working condition and oil lubricating situation, and degree of tightness do not need special spanner, only needs the very low general tool of configuration one price can make things convenient for degree of tightness, examination and maintenance have been made things convenient for, the suitable production in enormous quantities in enormous quantities.
Description of drawings Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model plan view.
Fig. 3 is another mode of execution plan view of the utility model.
Fig. 4 is the utility model mode of execution plan view again.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments for embodiment.As shown in Figure 1, visual valve cap is made up of valve cap body and visible mirror, and valve cap body 1 middle part is provided with the manhole of boss 6, interference fit visible mirror in the through hole.Boss 6 its effects in the manhole are conveniently to settle visible mirror and to its location, prevent downslide.Can find out also that from Fig. 1 visible mirror is made inner frame 4 by the metal circle and seal ring 5, high strength glass mirror 3 and fluorine rubber sealing layer 2 combine.Its assembly process is: at first place viton seal ring 5 in circular metal circle bottom, insert circular high-strength transparence glass 3 then, get final product through mould heat-sealing (secondary fluidisation) through fluorine rubber sealing layer 2.
As shown in Figure 2, be the plan view of Fig. 1 structure, the cross projection is made in valve cap body 1 outer, is convenient to use the general tool degree of tightness.
As shown in Figure 3, cross groove degree of tightness mechanism is established in the utility model valve cap body outer.As shown in Figure 4, valve cap body outer also can be hexagonal configuration degree of tightness mechanism.Its profile had been not only attractive in appearance, but also be convenient to common instrument degree of tightness, and was convenient and practical.
Valve cap body outer also can be made into
Or the concave, convex degree of tightness mechanism of in-line all can.
