Description
Technical field
The utility model relates to a kind of end cap, is specifically related to a kind of end cover of fan.
Background technique
At present, the end cap of the blower fan on market, in using process, the rotation of blower fan constantly can be impacted end cover of fan, therefore, weight is very large, is not easy to transport, long use can make end cover of fan immovable point cause wearing and tearing, cause end cover of fan fixing not firm, even come off, security incident occurs, and, existing end cap mostly is sealing mechanism, and radiating effect is not good, can't observe inner working condition.
Model utility content
The purpose of this utility model overcomes deficiency of the prior art, the end cover of fan provided, under the prerequisite of not gaining in weight, increases by a circle stiffening rib at the outer wall of bearing mounting hole, improve the soundness of end cap, and, the edge of end cap is provided with draw-in groove, improves the soundness connected, and on end cap, increase ventilation peep hole, be convenient to heat dissipation ventilation, structure is simple, has a good application prospect.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of end cover of fan, comprise the end cover body of round basin shape, described end cover body center is provided with annular boss, described annular boss is provided with bearing mounting hole, it is characterized in that: the outer wall periphery of described annular boss is provided with some stiffening ribs at equal intervals, end cover body outside described annular boss is provided with two symmetrical ventilation peep holes, the edge of described end cover body is provided with a circle draw-in groove, the edge of described end cover body is also extended with some pieces of mounting blocks laterally, described mounting blocks is four pieces, be fixed on the edge of end cover body at equal intervals, each mounting blocks is provided with the first fixed hole.
Aforesaid a kind of end cover of fan, is characterized in that: the shape of described stiffening rib is right-angle triangle, and its right angle side is close to the outer wall of annular boss.
Aforesaid a kind of end cover of fan, is characterized in that: the quantity of described stiffening rib is nine, is spacedly distributed at the outer wall periphery of annular boss.
Aforesaid a kind of end cover of fan, is characterized in that: described annular boss is provided with the second fixed hole be spacedly distributed, and described second fixed hole quantity is four.
The beneficial effects of the utility model are: end cover of fan of the present utility model, under the prerequisite of not gaining in weight, increase by a circle stiffening rib at the outer wall of bearing mounting hole, improve the soundness of end cap, and, the edge of end cap is provided with draw-in groove, improve the soundness connected, and on end cap, increase ventilation peep hole, be convenient to heat dissipation ventilation, structure is simple, has a good application prospect.
