Abstract
The utility model discloses a kind of metal blade device that rotor is facilitated to assemble, including metal blade, the compression spring with the matched rotor of the metal blade and for preventing rotor from loosening；The rotor includes motor shell and the magnet ring with the inner wall close-fitting of the cavity of the motor shell；The peripheral surface convex of the motor shell is equipped with hook, and the card slot of the hook and the recessed cavity inner wall in the metal blade fastens；The cavity inner bottom surface of the metal blade is circumferentially embedded with the equal compression spring of multiple elastic force, and the upper end of the compression spring presses on the bottom surface of the motor shell.With this structure design, passing through the cooperation of hook and card slot so that easily assembling is integrated for rotor and metal blade, meanwhile, by the setting of compression spring, hook and the reliable and stable connection of card slot can be effectively prevent, prevents the product caused by the two loosens abnormal.
Description
Technical field
The utility model is related to metal blade technical field more particularly to a kind of metal blade that rotor is facilitated to assemble dresses
It puts.
Background technology
Rotor under the prior art in metal blade assembling process, passing through the mandatory pressing of press, Zhi Hou mostly
Rotor and metal blade are fixed by mode for dispensing glue, set by this method, technique is cumbersome, and rotor is being pressed into metal
During the cavity of flabellum, the magnet ring in easy damaging rotor, and assemble in this way, reliability is also poor.
Utility model content
The purpose of this utility model is to provide a kind of convenient for assembly, reliable metal blade devices of stable connection.
For this purpose, the utility model uses following technical scheme：
A kind of metal blade device that rotor is facilitated to assemble, including metal blade and matched turn of the metal blade
Son and the compression spring for preventing rotor from loosening；The rotor includes motor shell and the inner wall with the cavity of the motor shell
The magnet ring of close-fitting；The peripheral surface convex of the motor shell is equipped with hook, the hook and the recessed chamber in the metal blade
The card slot of internal wall fastens；The cavity inner bottom surface of the metal blade is circumferentially embedded with the equal compression spring of multiple elastic force, described
The upper end of compression spring presses on the bottom surface of the motor shell.
Wherein, the lower face circumferential direction integrated punching of the motor shell is provided with multiple positioning grooves, the positioning groove with
The compression spring matches.
Wherein, the card slot is molded with the metal blade using integrated punching.
Wherein, the hook is circumferentially distributed in the upper end of the motor shell peripheral surface.
Wherein, it is embedded with shaft in the middle part of the cavity inner bottom surface of the metal blade.
The beneficial effects of the utility model：The utility model includes metal blade and matched turn of the metal blade
Son and the compression spring for preventing rotor from loosening；The rotor includes motor shell and the inner wall with the cavity of the motor shell
The magnet ring of close-fitting；The peripheral surface convex of the motor shell is equipped with hook, the hook and the recessed chamber in the metal blade
The card slot of internal wall fastens；The cavity inner bottom surface of the metal blade is circumferentially embedded with the equal compression spring of multiple elastic force, described
The upper end of compression spring presses on the bottom surface of the motor shell.With this structure design, pass through the cooperation of hook and card slot so that rotor
It easily assembles and is integrated with metal blade, meanwhile, by the setting of compression spring, hook and card slot can be effectively prevent reliable and stable
Connection, prevent product caused by the two loosens abnormal.
Description of the drawings
Fig. 1 is a kind of structure diagram for the metal blade device that rotor is facilitated to assemble of the utility model.
Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, a kind of metal blade device that rotor is facilitated to assemble in the present embodiment, including metal blade 1 and institute
State 1 matched rotor of metal blade and the compression spring 3 for preventing rotor from loosening；The rotor include motor shell 21 and
With the magnet ring 22 of the inner wall close-fitting of the cavity of the motor shell 21；The peripheral surface convex of the motor shell 21 is equipped with hook 211,
The card slot 11 of the hook 211 and the recessed cavity inner wall in the metal blade 1 fastens；The cavity of the metal blade 1
Inner bottom surface is circumferentially embedded with the equal compression spring 3 of multiple elastic force, and the upper end of the compression spring 3 presses on the bottom of the motor shell 21
Face, the lower face circumferential direction integrated punching of the motor shell 21 are provided with multiple positioning grooves, the positioning groove and the compression spring
3 match, and the card slot 11 is molded with the metal blade 1 using integrated punching, and the hook 211 is circumferential to be distributed in the horse
Up to the upper end of 21 peripheral surface of shell, shaft 4 is embedded in the middle part of the cavity inner bottom surface of the metal blade 1.
The metal blade device designed using the above structure, in assembling, it is only necessary to can be by rotor with smaller pressure
It being pressed into metal blade, the rotor bottom after assembling is acted on by the reaction force of compression spring, and hook and card slot is promoted to be fitted close,
And then prevent the generation of the product abnormal phenomenon caused by the two is in long-term engagement process due to loosening.It assembles in this way,
It is at low cost, it is convenient and efficient, it is reliable and stable.
The technical principle of the utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With novel principle, and it cannot be construed to the limitation to scope of protection of the utility model in any way.Based on explanation herein,
Those skilled in the art would not require any inventive effort the other specific embodiments that can associate the utility model,
These modes are fallen within the scope of protection of the utility model.
