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 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. 1-5, the present invention provides a technical solution: brushless fan centrifugation impeller joint structure, including upper cover plate 1 and

lower apron

4, 1 lower extreme fixedly connected with inserted bar 2 of upper cover plate, and 2 outside fixedly connected with stoppers 3 of inserted bar, jack 5 has been seted up to 4 inside inboards of lower apron, and the mutual block of jack 5 and inserted bar 2, upper cover plate 1 and the inside fixedly connected with block board 6 of

lower apron

4, and 6 inside reservations of block board have

block groove

7, 7 inside blocks in block groove are connected with impeller piece 8.

Further, the specification of upper cover plate 1 is unanimous with

lower cover plate

4, and 1 upper end fixedly connected with plug connector 9 of upper cover plate, and the inside reservation of plug connector 9 has interface 10, and interface 10 has two sets ofly about the equidistant distribution of 9 horizontal central lines of plug connector, interface 10 is on the output shaft of the convenient integral erection fan of plug connector 9, and interface 10 can be easy to assemble and dismantle with the mutual block of the spring card button on the output shaft.

Further, inserted bar 2 is inside threaded groove structure, and 2 inside detachably of inserted bar is connected with screw 11,

screw

11 and 2 inside threaded groove looks adaptations of inserted bar, and inserted bar 2 and jack 5 correspond and have four groups at upper cover plate 1 and the inside annular distribution of lower cover plate 4, and screw 11 and inserted bar 2 can carry out threaded connection to guarantee that upper cover plate 1 and lower cover plate 4 carry out stable connection, increased the stability of connecting.
