Description
Technical Field
The utility model relates to a crankshaft horizontal output's general gasoline engine, especially a crankshaft horizontal output's general gasoline engine silencer protection casing.
Background
At present, the protective cover on the general engine silencer mostly adopts metal stamping parts, and is formed by stamping a single plate-shaped opening, so that the structure is not only complex and difficult to process, but also has heavier weight, and the size of the opening is limited, thereby being not beneficial to the heat dissipation of the silencer.
The utility model discloses a utility model patent of "a general gasoline engine silencer protection cover" is disclosed in CN207583476U, the dustcoat includes the carriage of being connected with the silencer be provided with the wire net that constitutes by cylindrical steel wire on the carriage. Although the silencer increases the heat dissipation area and is beneficial to the heat dissipation of the silencer, the silencer has limited heat dissipation effect, and meanwhile, the silencer protection outer cover of the mechanism cannot prevent rain and snow from entering, and particularly cannot prevent the rain and snow from entering the engine when being used on a snow sweeper, so that the damage to the engine is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a gasoline engine silencer protection casing of bent axle horizontal output that the radiating effect is good.
The utility model aims at realizing through such technical scheme, a crankshaft horizontal output's general gasoline engine silencer protection casing, including the protection casing body the up end of protection casing body is provided with the shutter the equal vertical heat dissipation muscle that is provided with of left side, right side and the rear end face of protection casing body.
In order to improve the strength, a reinforcing rib surrounding the louver is arranged on the upper end face of the protective cover body and positioned at the outer edge of the louver.
In order to shield the immersion of snow rain, a semi-surrounding baffle plate used for shielding the front side surface and the right side surface is arranged on the inner wall of the protective cover body.
In order to drain snow rain, a groove-shaped waterproof belt is arranged on the lower portion of the right side face of the protective cover body.
Further described, the trough-like flashing strip is arranged horizontally.
In order to make the structure pleasing to the eye, play simultaneously prevent scalding, waterproof the left surface of protection casing body is provided with outside convex gas vent, the gas vent is the polygon that is the rule form.
In order to reduce weight, the protective cover body is made of thermoplastic plastic.
To further reduce weight, the plastic part is a single layer.
Since the technical scheme is used, the utility model has the advantages of structural design is ingenious, use reliably, low cost, adopt it not only to improve the radiating effect, but also can effectually prevent the invasion of sleet, prevented the harm to the engine to, through plastics injection moulding, alleviateed weight, reduced the manufacturing degree of difficulty.
Drawings
The drawings of the utility model are as follows:
fig. 1 is a schematic structural view of the present invention;
fig. 2 is a left side view of the present invention;
fig. 3 is a bottom view of the present invention.
Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the accompanying drawings, but the present invention is not limited to these embodiments, and any modifications or substitutions in the basic spirit of the embodiments will still fall within the scope of the present invention as claimed in the appended claims.
Example 1: as shown in fig. 1, 2 and 3, the general gasoline engine muffler protective cover with the crankshaft horizontally output comprises a protective cover body 1, wherein a shutter 3 is arranged on the upper end face of the protective cover body 1, and heat dissipation ribs 4 are vertically arranged on the left side, the right side and the rear end face of the protective cover body 1.
In order to improve the strength of the shield body and improve the impact resistance, a reinforcing rib 6 surrounding the louver 3 is arranged on the upper end surface of the shield body 1 and positioned at the outer edge of the louver 3.
In order to block the invasion of snow rain, a semi-surrounding baffle 5 for blocking the front side and the right side is arranged on the inner wall of the protective cover body 1.
In order to drain snow rain on the protection cover body, a groove-shaped waterproof belt 2 is arranged on the lower portion of the right side face of the protection cover body 1.
Further described, the groove-like flashing strip 2 is arranged horizontally.
In order to improve the aesthetic measure, an air outlet 7 protruding outwards is arranged on the left side surface of the protective cover body 1, and the air outlet 7 is a regular polygon.
In order to reduce weight and manufacturing difficulty, the protective cover body 1 is a thermoplastic plastic piece. This reduces the volume and mass, and reduces the cost.
To further reduce weight, the plastic part is a single layer.
In the utility model, the louver 3 and the heat dissipation ribs 4 are adopted, so that the heat dissipation area is increased, and the heat dissipation effect is better; meanwhile, when rain and snow are splashed on the protective cover body, the rain and snow can be prevented from immersing the engine through the semi-surrounding baffle 5, the groove-shaped waterproof belt 2 and the exhaust port 7, and the engine is effectively protected.
