Abstract
A kind of bonnet for DC brushless motor, including body and fixed part, body two ends are provided with holding section；Fixed part is the punching structure being arranged on body, smooth with body excessive is connected；And at least two reinforcements it are symmetrically arranged with in junction.By increasing the holding section of concave in this utility model so that for the bonnet of DC brushless motor before fastening, accurate positioning, and be difficult to after tightening loosen, effectively prevent install not in place or because of the loosening hidden danger brought.
Description
Technical field
This utility model relates to blower fan and manufactures field, particularly relates to a kind of bonnet for DC brushless motor.
Technical background
Blower fan by high speed rotating, improves gas pressure and supplies gas side by side body, shake in real work in real work
Relatively big, but at the bonnet for DC brushless motor in the middle of installation process, all directly positioned by securing member and fix, this
There is relatively high tolerance due to hole, location in sample so that positions inaccurate, and fix bonnet simply by securing member, in real work
In be susceptible to loosen, cause fault.
The defect existed in view of the above-mentioned existing bonnet for DC brushless motor, the present inventor produces based on being engaged in this type of
Practical experience that product engineer applied enriches for many years and Professional knowledge, and coordinate the utilization of scientific principle, research and innovation the most in addition, to
Found a kind of novel bonnet for DC brushless motor so that it is have more practicality.
Utility model content
This utility model provides a kind of bonnet for DC brushless motor, by increasing the engaging of concave
Portion so that for the bonnet of DC brushless motor before fastening, accurate positioning, and be difficult to after tightening loosen, effectively prevent
Not in place or because of the loosening hidden danger brought because installing.
The technical scheme that this utility model is taked is: a kind of bonnet for DC brushless motor, including body with fixing
Portion, body two ends are provided with holding section；Fixed part is the punching structure being arranged on body, smooth with body excessive is connected；And
At least two reinforcements it are symmetrically arranged with in junction；Holding section is concave hole, is symmetricly set in body two ends；And to
Internal projection side is near fixed part.
Further, reinforcement is punching press reinforcement.
Further, the thickness of body is 1 ~ 2mm.
Further, the thickness of body is 1.5mm.
Further, fixed part is symmetrically arranged with at least two installing hole.
Further, installing hole is unthreaded hole.
After have employed technique scheme, this utility model has a following beneficial effect:
By increasing the holding section of concave so that for the bonnet of DC brushless motor before fastening, accurate positioning,
And be difficult to after tightening loosen, effectively prevent install not in place or because of the loosening hidden danger brought；By increasing punching structure
Reinforcement so that ensureing on the premise of bonnet intensity, reducing material thickness, effectively saved the cost of raw material.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it is therefore apparent that the accompanying drawing in describing below is only
Some embodiments described in this utility model, for those of ordinary skill in the art, are not paying creative work
Under premise, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of bonnet in this utility model for DC brushless motor；Fig. 2 is the right view of Fig. 1；
1 body, 2 fixed parts, 3 holding sections, 21 installing holes.
Detailed description of the invention
For the technical scheme making those skilled in the art be more fully understood that in this utility model, below in conjunction with this reality
With the accompanying drawing in new embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that
Described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on this utility model
In embodiment, the every other enforcement that those of ordinary skill in the art are obtained under not making creative work premise
Example, all should belong to the scope of this utility model protection.
This utility model embodiment uses the mode gone forward one by one to write.
As it is shown in figure 1, a kind of bonnet for DC brushless motor, including body 1 and fixed part 2, body 1 two ends are arranged
There is holding section 3；Fixed part 2 is the punching structure being arranged on body 1, smooth with body 1 excessive is connected；And it is symmetrical in junction
It is provided with two reinforcements 4；Holding section 3 is concave hole, is symmetricly set in body 1 two ends；And inwardly protruding side leans on
Nearly fixed part 2；By increasing the holding section 3 of concave so that bonnet before fastening, accurate positioning, and being difficult to after tightening
Loosen, effectively prevent install not in place or because of the loosening hidden danger brought；By increasing the reinforcement of punching structure so that
On the premise of ensureing bonnet intensity, reduce material thickness, effectively saved the cost of raw material.
Wherein, reinforcement 4 is punching press reinforcement, easily realizes in technique, it is not necessary to use special installation can realize adding
The processing of strong muscle 4, human cost is controlled；The thickness of body 1 is 1.5mm, reduces about 1mm than existing bonnet thickness；Fixed part 2
Being symmetrically arranged with 4 installing holes 21, installing hole 21 is unthreaded hole, there is the upper deviation, in order to securing member penetrates, in installation process first
By holding section, bonnet is positioned, after having positioned, use securing member, by installing hole 21, bonnet is fixed.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses this practicality new
Type.Multiple amendment to these embodiments will be apparent from for those skilled in the art, is determined herein
The General Principle of justice can realize in the case of without departing from spirit or scope of the present utility model in other embodiments.Cause
This, this utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest scope consistent with features of novelty.
