The utility model discloses a sealing structure. An arc-shaped portion is arranged on the strip portion, a groove is arranged on the arc-shaped surface of the arc-shaped portion, and a plurality of pressure bands are arranged on the bottom surface of the groove. The utility model has the advantages that the cylinder head cover is sealed by the strip portion, and the cylinder head is sealed by the clamping groove and the pressure wave band on the arc portion, so that the sealing performance of the cylinder head cover and the cylinder head is not improved.
Description
Technical Field
The utility model relates to the technical field of sealing elements, in particular to a sealing structure.
Background
The sealing between the two parts is designed to be a plane in a sealing area needing sealing between the two parts, such as paper gaskets and rubber parts. With the development of production technology, more and more designs adopt unconventional structures due to structural problems. For example, in the diesel engine with the overhead camshaft structure, the camshaft is arranged on the cylinder cover, so that a camshaft hole is processed, when part of the cylinder cover is designed, one end of the cylinder cover can be in a semicircular hole state, when the cylinder cover and the cylinder cover are combined, the semicircular hole needs to be sealed by the middle sealing piece, the cylinder cover is also processed into the semicircular hole by the part of the cylinder cover, the half hole is sealed by a bowl-shaped plug and the like, but the structure is likely to cause oil leakage and air leakage due to the processing problem of the production port, and the sealing effect is poor.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of how to improve the sealing performance of a cylinder head cover and a cylinder head.
In order to solve the technical problems, the utility model provides the following technical scheme:
the utility model provides a sealing structure, be equipped with arc portion on the bar portion, be equipped with the recess on the arcwall face of arc portion, the bottom surface of the groove is equipped with a plurality of pressure wave sections.
Seal up the cylinder head cover through the bar portion, seal up the cylinder head through draw-in groove and pressure wave band on the arc portion, can not improve the leakproofness to cylinder head cover and cylinder head.
Preferably, the two sides of the strip-shaped part are provided with convex parts.
Preferably, the number of the press wave bands is two.
Preferably, the strip-shaped portion and the arc-shaped portion are both rubber elastic pieces.
Compared with the prior art, the utility model has the beneficial effects that:
seal up the cylinder head cover through the bar portion, seal up the cylinder head through draw-in groove and pressure wave band on the arc portion, can not improve the leakproofness to cylinder head cover and cylinder head.

Fig. 1 is a schematic structural view of an embodiment of the present invention;
FIG. 2 is a cross-sectional view A-A of FIG. 1;
fig. 3 is a schematic view of an installation structure of an embodiment of the present invention.
Detailed Description
In order to facilitate the understanding of the technical solutions of the present invention for those skilled in the art, the technical solutions of the present invention will be further described with reference to the drawings attached to the specification.
In this application, unless expressly stated or limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can include, for example, fixed connections, removable connections, or integral parts; the connection can be mechanical connection, electrical connection or communication; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
In this application, unless explicitly stated or limited otherwise, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
Referring to fig. 1 to 3, this embodiment discloses a sealing structure, including bar 1 and arc 2, bar 1 is used for sealed joint cylinder head cover 3, bar 1 one end is fixed and arc 2 of joint on cylinder head 4 again, it should explain, be equipped with bellied arc snap ring 41 on the camshaft hole of cylinder head 4, be equipped with the recess 21 of joint arc snap ring 41 on the arc of arc 2, specifically, the both sides face of recess 21 corresponds the laminating with the both sides face of arc snap ring 41, recess 21 bottom surface is equipped with a plurality of pressure wave bands 22 for sticis arc snap ring 41 top surface and realizes sealedly, in this embodiment, is equipped with two pressure wave bands 22, forms double wave seal structure.
Seal up cylinder head cover 3 through bar portion 1, seal up cylinder head 4 through draw-in groove 21 and pressure wave band 22 on the arc portion 2, can not improve the leakproofness to cylinder head cover 3 and cylinder head 4.
Furthermore, protruding parts 11 are arranged on two sides of the strip-shaped part 1, so that the clamping strength of the strip-shaped part 1 to the cylinder head cover 3 is improved.
Still further, the strip-shaped part 1 and the arc-shaped part 2 are both rubber elastic pieces.
The installation process of the utility model is as follows: firstly, the strip-shaped part 1 is sealed and clamped on the cylinder head cover 3 to ensure that the sealing structure is fixed on the cylinder head cover 3, then the cylinder head cover 3 is covered on the cylinder cover 4, meanwhile, the groove 21 on the arc-shaped surface of the arc-shaped part 2 is clamped on the arc-shaped clamp ring 41, and the two wave pressing bands 22 tightly press the top surface of the arc-shaped clamp ring 41 to form a double-wave sealing structure.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
The above-mentioned embodiments only represent the embodiments of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the concept of the present invention, and these embodiments are all within the protection scope of the present invention.
