Abstract

The utility model discloses a case cover of an air-cooled gasoline engine case body, which comprises: the box cover body is provided with a plurality of bolt holes, the front face of the box cover body is provided with a plurality of heat dissipation rib plates, a gap between every two adjacent heat dissipation rib plates is a heat dissipation air duct, and a plurality of reinforcing rib plates are radiated outwards from positions, located in the bolt holes, on the rear side face of the box cover body. According to the air-cooled gasoline engine case cover, the arrangement of the heat dissipation rib plates and the heat dissipation air channels improves the heat dissipation capacity of the case cover, can reduce the engine oil temperature of a gasoline engine, and the reinforcing rib plates can improve the strength of the case cover and ensure the service life of the case cover.

Description

Case cover of air-cooled gasoline engine case body

Technical Field

The utility model relates to the technical field of gasoline engine case covers, in particular to a case cover of an air-cooled gasoline engine case body.

Background

A plurality of bolt holes are generally processed on the existing gasoline engine case cover, so that the strength of the existing gasoline engine case cover is reduced, and the case cover generally has no cooling and heat dissipation structure, so that the engine oil temperature of the gasoline engine is higher.

Therefore, how to provide a box cover of an air-cooled gasoline engine box body with high strength and a heat dissipation function is a problem which needs to be solved urgently by the technical personnel in the field.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a box cover of an air-cooled gasoline engine box body, which has high strength and a heat dissipation function.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a tank cover of an air-cooled gasoline engine tank body, comprising: the box cover comprises a box cover body, wherein a plurality of bolt holes are formed in the box cover body, a plurality of heat dissipation rib plates are arranged on the front side of the box cover body, a gap between every two adjacent heat dissipation rib plates is a heat dissipation air duct, and a plurality of reinforcing rib plates are outwards radiated at positions, located in the bolt holes, on the rear side face of the box cover body.

According to the technical scheme, compared with the prior art, the utility model discloses the case cover of the air-cooled gasoline engine case body, and the arrangement of the heat dissipation rib plates and the heat dissipation air duct improves the heat dissipation capability of the case cover, can reduce the engine oil temperature of the gasoline engine, and can improve the strength of the case cover through the reinforcing rib plates, thereby ensuring the service life of the case cover.

Furthermore, the case cover body is made of die-casting aluminum alloy, so that the case cover is good in heat dissipation performance and easy to cast.

Furthermore, the heat dissipation rib plates and the reinforcing rib plates are integrally connected with the box cover body, so that the cover plate is simple in manufacturing process.
