In order to solve the technical problems, the utility model is realized by the following technical scheme:
the utility model provides a dustproof and waterproof's fan support structure, includes fan support, sleeve and fan hub, the sleeve rotate connect in on the fan hub, the fan support be fixed in on the sleeve, fan hub outer end is provided with fan hub seat circle, fan hub seat circle pass through hexagon head bolt fastening in fan hub outer end, the sleeve outer end totally closed is provided with the shield.
Preferably, a bearing is arranged between the sleeve and the fan hub, check rings are arranged at the inner end and the outer end of the bearing, and a sealing ring with a metal ring is arranged between the check rings and the bearing.
Preferably, the dust cover is of a disc-shaped sheet structure, the outer ring of the sheet structure is bent to form an annular groove, and the outer wall of the annular groove abuts against the inner wall of the sleeve to form a sealing surface.
Compared with the prior art, the utility model has the following advantages:
the utility model mainly designs the fan support structure, cancels the existing sealing structure, selects the sealing ring with the metal ring on the side of the fan support matched with the hub of the bearing fan (the shape of the metal ring and the sealing ring is not limited), upgrades the dustproof and waterproof function of the end, the sealing form of the other side of the bearing is not limited, adopts the dustproof cover to fully seal the bottom end of the fan support on the outer side of the bearing, upgrades the dustproof and waterproof function and the attractive degree of the end, and the novel structure can prolong the service life of the fan support and reduce the production cost and the after-sale cost.

Detailed Description
In order that those skilled in the art will better understand the technical solutions of the present utility model, preferred embodiments of the present utility model will be described below with reference to specific examples, but it should be understood that the drawings are for illustrative purposes only and should not be construed as limiting the present patent; for the purpose of better illustrating the embodiments, certain elements of the drawings may be omitted, enlarged or reduced and do not represent the actual product dimensions; it will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The positional relationship depicted in the drawings is for illustrative purposes only and is not to be construed as limiting the present patent.
As shown in fig. 1 and 2, the present utility model provides a dustproof and waterproof fan support structure, which comprises a fan hub 1, a retainer ring 2, a bearing 3, a sealing ring 31, a fan hub race 4, a hexagon head bolt 5, a dustproof cover 6, a fan support 7 and a sleeve 8.
In this embodiment, sleeve 8 rotate connect in on the fan hub 1, fan support 7 is fixed in on the sleeve 8, fan hub 1 outer end is provided with fan hub seat circle 4, fan hub seat circle 4 is fixed in through hexagon head bolt 5 fan hub 1 outer end, sleeve 8 outer end totally closed is provided with shield 6, promotes fan support 7 dustproof waterproof performance, increases fan support 7 life, reduces after-sale failure rate.
Further, a bearing 3 is arranged between the sleeve 8 and the fan hub 1, a retainer ring 2 is arranged at the inner end and the outer end of the bearing 3, a sealing ring 31 with a metal ring is arranged between the retainer ring 2 and the bearing 3, the existing sealing structure is eliminated, and one press-fitting procedure is reduced.
Further, the dust cover 6 is in a disc-shaped sheet structure, the outer ring of the sheet structure is bent to form an annular groove 61, and the outer wall of the annular groove 61 abuts against the inner wall of the sleeve 8 to form a sealing surface. The curved annular groove 61 can provide self-elastic force, and the sheet structure can be automatically embedded into the sleeve 8 to form a sealing structure under the action of external force, so that a sealing gasket and a fastening component are not required to be additionally arranged.
The utility model solves the problem that the service life of the bearing is reduced due to self-produced impurities as the service time of the existing fan bracket structure is increased, reduces materials and working procedures, saves cost and reduces after-sales.
