Detailed Description

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 of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides a fan motor with louvre seal structure, including motor body 1 and end shell 2, set up fluted 3 and opening 4 on the end shell 2, louvre 5 has been seted up to opening 4 department, internal thread on the inner wall of opening 4 passes through threaded connection with the external screw thread on the apron 10 bottom disc 12 outer wall, install handle 14 on the apron 10, can make things convenient for rotatory apron 10 more through handle 14, rotate apron 10 to disc 12 and opening 4 threaded connection, apron 10 can laminate with recess 3, louvre 5 at this moment is sheltered from by apron 10, consequently, can effectually prevent that dust or liquid from entering into motor inside through louvre 5 and causing the damage to motor internals, the user can decide by oneself whether need to install apron 10 on the end shell 2 of motor, be equipped with the mounting to apron 10 rigidity on the end shell 2.

Specifically, as shown in fig. 3, the fixing member includes the supporting block 6 of the inner wall fixed connection of the end shell 2, the supporting block 6 has a round block 7 through the butt of the spring 9, the round rod 8 of the upper fixed connection of the round block 7 and the end shell 2 sliding connection, the circular groove 13 and the opening 11 are provided on the cover plate 10, the clamping of the circular groove 13 is provided with the snap ring 15, the bottom fixed connection of the snap ring 15 extends into the clamping block 16 of the opening 11, the snap ring 15 is clamped with the circular groove 13, because the clamping force of the snap ring 15 and the circular groove 13 is greater than the elastic force given to the round rod 8 by the spring 9, when the snap ring 15 rotates along with the cover plate 10, the round rod 8 cannot push the clamping block 16 to separate the snap ring 15 from the circular groove 13, and when the snap ring 15 is clamped with the circular groove 13, the bottom of the clamping block 16 is flush with the bottom of the cover plate 10, and the round rod 8 can be effectively prevented from extending into the opening 11.
