Detailed Description

In order to fix right side meal backplate at any time conveniently to reach the purpose of the maintenance engine of being convenient for, the embodiment of the utility model provides an engine housing. The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present embodiment provides an engine cover casing, including casing 1, rear side guard plate 2, front side guard plate 3 and right side guard plate 4, rear side guard plate 2 and front side guard plate 3 all pass through screw and casing 1 fixed connection, and right side guard plate 4 rotates through the pivot with casing 1 to be connected, and a plurality of first louvres 21 have all been seted up to the surface of rear side guard plate 2, front side guard plate 3 and right side guard plate 4, prevent that the engine from shortening life because of the high temperature.

The seat is rotated to the inboard of right side guard plate 4 is installed, rotates and installs between seat and the 1 inside wall of casing and open the rotary device 6 that the angle was fixed at any time to right side guard plate 4, fixes right side guard plate 4 at any time to need not the manual work and support right side guard plate 4 and be convenient for fix right side guard plate 4 on the angle of the maintenance engine of being convenient for.

For better to the 4 support effects of right side guard plate, rotary device 6 includes connecting rod 61 and fixed column 62, and fixed column 62 passes through connecting seat and 1 inside wall fixed connection of casing, and the one end of connecting rod 61 rotates with the rotation seat to be connected, and the other end and the fixed column 62 swing joint of connecting rod 61, spout 621 has been seted up to fixed column 62's lateral wall, and the inside movable mounting of spout 621 has the annular stopper 622 that plays limiting displacement to connecting rod 61.

The manual work rotates right side guard plate 4, connecting rod 61 receives the turning force to take place to rotate and laminate mutually with fixed column 62 all the time, after right side guard plate 4 rotates to required angle, annular stopper 622 that will be located on fixed column 62 slides, it is spacing to connecting rod 61, make connecting rod 61 can not take place to rotate at will, right side guard plate 4 this moment, form a triangle-shaped between 1 inside wall of casing and the connecting rod 61 three, thereby play the effect of support to right side guard plate 4, it is fixed at any time to reach right side guard plate 4, the purpose of engine is conveniently maintained.

In order to promote the limiting effect on the connecting rod 61, the connecting rod 61 is internally provided with a waist-shaped hole 611 matched with the fixing column 62, so that the connecting rod 61 is always attached to the fixing column 62 and rotates along a given track, the outer side wall of the connecting rod 61 is provided with a plurality of limiting grooves 612 matched with annular limiting blocks 622, the limiting grooves 612 and the annular limiting blocks 622 are matched for use, and the fixing effect on the connecting rod 61 is better.

Spout 621 sets up to L type structure for annular stopper 622 can rotate and slide in the inside emergence of fixed column 62, when needs are closed with the upset of right side guard plate 4, rotates the shrink with annular stopper 622 at the innermost of spout 621, and is spacing to annular stopper 622 this moment, makes when rotating right side guard plate 4, annular stopper 622 can not appear receiving the phenomenon of external force and the sliding block of spacing groove 612, thereby avoids appearing the condition that right side guard plate 4 closed not last.

In order to make the bore of first louvre 21 change as required, thereby under the circumstances of guaranteeing engine radiating effect, can be fine again prevent debris invasion, the surface slidable mounting of rear side guard plate 2 has sliding plate 22, a plurality of second louvre 221 have been seted up to sliding plate 22's surface, second louvre 221 and first louvre 21 mutually perpendicular, slide on rear side guard plate 2 through sliding plate 22, make first louvre 21 and second louvre 221 crisscross each other, thereby change the size of the actual thermovent of first louvre 21, reach the radiating effect that can guarantee the engine, can be fine again prevent the mesh of debris invasion.

In order to be convenient for link together right side guard plate 4 and casing 1, the maintenance hole 11 of being convenient for the maintenance is seted up to casing 1's upper surface, and maintenance hole 11 sets up to polygonized structure, can increase the bore of maintenance mouth, convenient maintenance.

The outer fixed surface of right side guard plate 4 installs the handle 41 of being convenient for to draw and getting, and right side guard plate 4 is inside to rotate through rolling disc 5 and to install L type piece 51, and casing 1's inboard fixed mounting has a connecting block, and the connecting block is inside seted up with L type piece 51 assorted recess 12, with the closed back of the upset of right side guard plate 4, rotates rolling disc 5 for L type piece 51 and recess 12 mutually perpendicular, thereby accomplish the function of being connected between right side guard plate 4 and casing 1.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
