Abstract
An oil filler cap sealing structure of an engine comprises an oil filler cap; and a seal ring and a valve chamber cover oil filler matched with the oil filler cap are arranged on the oil filler cap through mounting grooves. The utility model is characterized in that an oblique groove used for connection is formed at the lower part of the oil filler cap, and a groove mouth communicated with the oblique groove is arranged at the end part of the oil filler cap; and a lug boss matched with the oblique groove is arranged on the inner wall of the valve chamber cover oil filler. During sealing, the lug boss on the inner wall of the valve chamber cover oil filler is screwed in the oblique groove through the groove mouth to be connected. The seal ring adopts an O-shaped ring, and the inner wall of the valve chamber cover oil filler is a tapered surface with a larger outer part and a smaller inner part. In the utility model, the scheme that the wide-angle spiral oblique groove is matched and connected with the lug boss is adopted, and conical surface seal is also adopted, besides, the design is optimized on the basis of the full-thread screwing seal way, so that effective seal can be ensured only by rotating 180 DEG; and the structure is simple, and the assembly is convenient.
Description
Technical field
The utility model relates to a kind of lid sealing configuration, relates in particular to a kind of motor cap sealing configuration.
Background technique
Existing motor cap sealing configuration mostly is by rotation displacement mode and reaches pretension applying sealing purpose; Wherein have by spring clip elastic force to guarantee effective applying, but spring clip in long-term using process, elastic force can progressively be decayed, and finally causes gasket seal effectively not compress and oil impregnate, and this complex structure.Also having structure commonly used is Full Thread FT screwing hermetic mode, and this mode sealing effect is good, and it is more only to screw the number of turns, and installation time is long partially.
Chinese patent 02238175.9 discloses a kind of pressure-bearing with radially O type circle sealing and has rotated locking interface device, mainly by plug, socket, O type circle, backing-up screw and resilient pad are formed with compressing with cushion, and wherein plug and socket is a tube-shaped structure, be shaped on O type circle seal groove on the former its, a plurality of lugs and shoulder, the latter is shaped on a plurality of hooks on it, is shaped on a nail hole that backing-up screw is installed on a hook therein.To compress with cushion and be nested on the plug, and have certain flexible O type circle and insert in the O type circle seal groove, angle of plug and socket rotation is made lug combine with hook to load onto backing-up screw can become an integral body that seals.The utility model sealing is easy to be reliable, and physical dimension is little, and is in light weight, can be common to pipeline and function component, and working service is repaired simple and easy.Its deficiency is, complex structure, use convenient not enough.
The model utility content
The purpose of this utility model be to provide a kind of simple in structure, assembling is convenient, can guarantee the effectively cap sealing configuration of sealing again.
The utility model is to realize by the following technical solutions: a kind of motor cap sealing configuration comprises that cap, oil filler cover the valve chamber cover oil filler that seal ring and adaptive cap are set by mounting groove; It is characterized in that: described cap bottom has been provided with the oblique slot of anastomosis, 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 by notch and connects.
For better sealing, described seal ring is an O type circle.
Described valve chamber cover mouth inwall is the little conical surface of outer imperial palace.
Using method is, the cap notch being aimed at the boss of valve chamber cover mouth inwall presses, allow boss be in the cap skewed slot, dextrorotation turnback then, by rotation guarantee seal ring that oil filler covers along valve chamber cover downwards and the oil filler wall effectively compress, to reach sealing effect, to satisfy assembly and use requirements.
Adopt the sealing of O type circle between cap and the valve chamber cover, O type circle internal diameter is slightly less than the external diameter of cap mounting groove, guarantees that O type circle and oil filler are stamped certain magnitude of interference, guarantees that oil can not ooze out between O type circle and cap.
Concrete advantage of the present utility model and intention are summarized as follows: owing to adopt wide-angle spiral oblique slot to cooperate connecting mode with boss, be equipped with conical surface seal, optimal design on the basis of Full Thread FT screwing hermetic mode, only depend on the Rotate 180 degree just can guarantee effective sealing, simple in structure, it is convenient to assemble.
Below in conjunction with drawings and Examples, cap described in the utility model is described in further detail.
