Description
Technical Field
The utility model belongs to a cylinder gasket, and particularly relates to a split type cylinder gasket for enhancing sealing performance.
Background
The cylinder gasket, also called cylinder liner, is positioned between the cylinder cover and the cylinder body, and has the functions of filling microscopic holes between the cylinder cover and the cylinder body, ensuring good tightness at the joint surface, further ensuring the sealing of the combustion chamber and preventing the air leakage of the cylinder and the water leakage of the water jacket. According to different materials, the cylinder gasket can be divided into a plurality of metal-asbestos gaskets, metal-composite gaskets, all-metal gaskets and the like, and sealing positions are not arranged on the traditional cylinder gasket, so that the condition of liquid leakage after installation is caused.
Disclosure of Invention
The present utility model has been made keeping in mind the above problems occurring in the prior art, and an object of the present utility model is to provide a split cylinder gasket which enhances sealability.
The aim of the utility model can be achieved by the following technical scheme: the utility model provides a split type cylinder gasket of reinforcing leakproofness, includes the cylinder gasket main part, its characterized in that, the cylinder gasket main part constitute by gasket one, gasket two and gasket three, gasket two be provided with protruding ring all around, both ends all are provided with a plurality of rubber bump about this arch is changed, gasket two on set up two combustion chamber holes, the edge of this combustion chamber hole is provided with a plurality of rubber bump, gasket two both ends all set up flutedly about, this recess is used for with gasket one and gasket three cooperation, the recess on be provided with elastic rubber strip.
In the split cylinder gasket with enhanced sealing performance, the top ends of the elastic rubber strips are respectively bent towards two sides.
In the split cylinder gasket with enhanced sealing performance, the top ends of the elastic rubber strips are respectively contacted with the first gasket and the third gasket.
In the split type cylinder gasket with enhanced sealing performance, threaded holes are formed in the first gasket, the second gasket and the third gasket, and the threaded holes of each layer of gasket correspond to each other.
Compared with the prior art, the split type cylinder gasket with enhanced sealing performance is provided with rubber salient points at the edge of the cylinder gasket and the edge of the combustion chamber hole, so that the friction force between the split type cylinder gasket and the cylinder cover is increased, and the sealing performance is further enhanced.

Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
As shown in fig. 1, 2 and 3, the split type cylinder gasket with enhanced sealing performance comprises a cylinder gasket main body and a positioning ring, wherein the cylinder gasket main body consists of a first gasket 1, a second gasket 2 and a third gasket 3, the periphery of the second gasket 2 is provided with a convex ring 4, the upper end and the lower end of the convex ring are respectively provided with a plurality of rubber protruding points 5, the second gasket 2 is provided with two combustion chamber holes 6, the edge of the combustion chamber holes 6 is provided with a plurality of rubber protruding points 5, the upper end and the lower end of the second gasket 2 are respectively provided with a groove, the grooves are used for being matched with the first gasket 1 and the third gasket 3, and elastic rubber strips 7 are arranged on the grooves.
During installation, the first gasket 1 and the third gasket 3 are extruded towards the second gasket 2, so that the rubber protruding points 5 are fully contacted with the cylinder cover and the cylinder, the rubber protruding points 5 have certain elasticity, deformation can be generated during contact, and the contact area is further increased.
Further, the top ends of the elastic rubber strips 7 are respectively bent to two sides, and the top ends of the elastic rubber strips 7 are continuously bent downwards in the extrusion process.
Further, the top ends of the elastic rubber strips 7 are respectively contacted with the first gasket 1 and the third gasket 3.
Further, threaded holes are formed in the first gasket 1, the second gasket 2 and the third gasket 3, the threaded holes of each layer of gasket are corresponding, the first gasket 1 and the third gasket 3 are inwards extruded through locking bolts, and the contact area between the rubber protruding points 5 and the cylinder cover is larger as the bolts are tightened.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
Although the terms first gasket 1, second gasket 2, third gasket 3, raised ring 4, rubber bumps 5, combustion chamber holes 6, elastomeric rubber 7, etc. are used more herein, the possibility of using other terms is not precluded. These terms are used merely for convenience in describing and explaining the nature of the utility model; they are to be interpreted as any additional limitation that is not inconsistent with the spirit of the present utility model.
