Abstract
The utility model specifically discloses a small -size gasoline engine muffler protection casing structure, including interior protection casing and outer protection casing, wherein outer protection casing comprises bead cover and muffler cover, its characterized in that: be provided with muffler assembly breach on the interior protection casing, muffler assembly breach is located the pressure connection's of muffler top, is equipped with with muffler assembly breach matched with level protrudingly on the muffler cover. The utility model adopts the above structure, fastening or unclamp and need not lean on the fabrication hole when nut is realized the pressure connection's of muffler assembly or is dismantled the gasoline engine, assembly or dismantle to finish and also do not need two extra rubber buffers to stop up the fabrication hole has reduced product cost when having reduced the complexity of part, and is easier when assembling gasoline engine protector to realize the invention mesh effectively.
Description
Technical field
The utility model belongs to mechanology technical applications, particularly relates to a kind of miniature gasoline engine silencer protective cover structure.
Background technique
Impeller on existing petrol engine and baffler all have employed protective housing protection; current protective housing comprises interior protective housing, impeller outer protective housing and baffler outer protective cover; first interior protective housing is fixed on petrol engine when assembling; again impeller is arranged on the impeller shaft of petrol engine; the air input joint of baffler is connected on the relief opening of petrol engine by tightening nut; after being bolted between impeller outer protective housing and baffler outer protective cover, be connected to form protective housing with interior protective housing together again, but in use have the following disadvantages:
1, because the gap between interior protective housing inwall and baffler is less, interior protective housing is provided with two auxiliary holes, tighten or loosen through auxiliary hole assembling or the dismounting that nut realizes the air input joint of baffler by instrument, when assembling or needing again two pieces rubber stopper to block auxiliary hole after having dismantled, required parts are more, need processing to all parts, manufacturing procedure is complicated, and cost of production is higher;
2, in prior art, petrol engine baffler outer cover comprises impeller outer protective housing and baffler outer protective cover two-part.When installing containment envelope, the more complexity not only increasing part of outer cover amount of parts, and strengthen the difficulty of construction assembling, the Percent of contact area required for specifications parameter simultaneously between each outer cover is higher, bring the important task of production management among stealth, the production brought and user cost larger.
Model utility content
The purpose of this utility model is to provide that a kind of cost is low, assembling and miniature gasoline engine silencer protective cover structure convenient for production.
The utility model object realizes by the following technical solutions: a kind of miniature gasoline engine silencer protective cover structure, comprise interior protective housing and outer protective cover, wherein, outer protective cover is made up of impeller chimney and muffler cover, described interior protective housing is provided with baffler assembling breach, described baffler assembling breach is positioned at the top of the air input joint of baffler, and muffler cover is provided with the horizontal projection of to assemble breach with baffler and matching.
Prior art impeller outer protective housing and baffler outer protective cover two structure unite two into one in being wholely set by described baffler outer protective cover, by the component of outer protective cover integrally property.
Owing to being provided with the utility model technique scheme on interior protective housing, formed by the assembling breach of containment envelope to petrol engine direction, the gap structure of described interior protective housing forms a larger space scope, therefore realize baffler air input joint assembling or dismounting time, the mode no longer needing instrument to pass auxiliary hole carries out tightening or loosening the operation of nut, install more for convenience, and the complexity of simultaneously protecting inner cover also reduces, and greatly improves industrial production efficiency.Assemble with baffler on interior protective housing the horizontal projection structure that breach matches owing to muffler cover being provided with one, therefore omit two pieces rubber stopper after installing when installing baffler tightening nut, can reduce costs.Impeller outer protective housing and baffler outer protective cover unite two into one by new design, and containment envelope structure is more simple, and production and fixing link thereof decrease assembling number of times, improve utilization efficiency and are conducive to commercial Application and management, thus more effectively realize goal of the invention.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows.
Fig. 1 is the structural representation of interior protective housing.
Fig. 2 is the structural representation of outer protective cover.
Fig. 3 is the assembling schematic diagram of the utility model on petrol engine.
Fig. 4 is the structural representation after the utility model assembling.
In figure, 1, interior protective housing; 2, outer protective cover; 3, impeller chimney; 4, muffler cover; 5, baffler assembling breach; 6, horizontal projection.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect clearly and be easy to understand, below in conjunction with the drawings and specific embodiments, the utility model being further elaborated.
A kind of miniature gasoline engine silencer protective cover structure, as shown in Figure 1, comprise interior protective housing 1 and outer protective cover 2, wherein, outer protective cover 2 is made up of impeller chimney 3 and muffler cover 4, it is characterized in that: interior protective housing 1 is provided with baffler assembling breach 5, described baffler assembling breach 5 is positioned at the top of the air input joint of baffler, and muffler cover 4 is provided with the horizontal projection 6 of to assemble breach 5 with baffler on interior protective housing 1 and matching.
As shown in Figure 1, impeller chimney 3 and muffler cover 4 are in being wholely set.
As shown in Figure 3,4, first interior protective housing 1 is fixed on petrol engine 7 when assembling, then impeller 8 is arranged on the impeller shaft of petrol engine, fix impeller by screw.The relief opening that the air input joint 10 of baffler 9 is connected to petrol engine is fixed by tightening nut, because interior protective housing connects petrol engine superstructure and forms an assembling breach being positioned at baffler, thus can damage from assembling breach when making to screw or unclamp tightening nut, there is larger space, be convenient to flexible operating.Muffler cover 4 has the projection of a relative baffler assembling breach 5, and this projection can play the effect of blocking assembling breach, can improve aesthetic property, the utility model eliminates the processing of auxiliary hole and eliminates rubber stopper parts, reduce manufacturing procedure, decrease component, reduce cost.
By reference to the accompanying drawings the embodiment of model utility is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
Claims (2)
