Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to
Following embodiments.
Fig. 1 is the schematic diagram of the tuning pipe mechanism of traditional screw-type, it can be seen that traditional tuning pipe mechanism
Middle tuning screw 3 is provided with the thread to match with nut 2, and tuning screw 3 lock onto the cover plate of cavity body filter by nut 2
On 1, when being tuned, tuning screw 3 is adjusted to suitable height after first unscrewing tuning screw 3, then tighten nut 2 and fix tune
Humorous screw 3, reach the purpose of tuning.This mode not only wastes time and energy, and sliding tooth easily occurs for tuning screw 3, turns simultaneously
Tuning screw 3 easily produces chip and entered in cavity body filter during dynamic, and the cover plate 1 of cavity body filter also easily occurs should
Force deformation.
A kind of tuning pipe mechanism for cavity body filter provided in the present embodiment is provided, filtered with cavity
The cover plate 1 of device connects, and for realizing the tuber function of cavity body filter, the mechanism includes tuning pipe 5 and bushing 4, bushing 4 are located at
On the cover plate 1 of cavity body filter, it is connected respectively with tuning pipe 5 and cavity body filter, tuning pipe 5 is connected in cavity by bushing 4
On the cover plate 1 of wave filter；Tuning pipe 5 includes tuning body and flange face, and flange face is fixed on the side of tuning body, tuning pipe
Body is connected with bushing 4, is connected in by flange face on bushing 4, and tuning body is provided with the first projection, and first is raised positioned at close
One end of flange face.It is hollow to tune body.It is hollow including cylindric hollow tuning body or regular polygon shape to tune body
Body.Bushing 4 includes bush body, bushing top surface and the second projection, bushing top surface and is fixed on the side of bush body, and second is convex
The inwall positioned at bush body is played, cover plate 1 of the bush body respectively with tuning pipe 5 and cavity body filter is connected, and passes through bushing top
Face is connected on the cover plate 1 of cavity body filter and fixed by the second projection.Second raised quantity is no less than 3.Bushing top surface
For circle.Bushing top surface is welded on the cover plate 1 of cavity body filter.
Fig. 3 is the structural representation of tuning pipe 5,4 kinds of ways of realization of the tuning pipe 5 is given from figure, wherein (3a)
For a kind of common form, i.e., flange face is regular circular flange face, while it is cylinder type hollow body to tune body；In (3b)
It is still cylinder type hollow body to tune body, but flange face is then irregular flange face；Flange face in (3c) and (3d) is equal
For regular circle shapes, but it is respectively regular hexagon hollow body and equilateral triangle hollow body to tune the body of pipe 5, from this four implementations
Example finds out that the way of realization for tuning body is various, and flange face can be that regular shape can also be irregular shape, can be with
Whether convenient etc. considered according to the site environment of reality and taking to determine；It is also not unique that the shape of body is tuned simultaneously,
When needing larger frictional force between tuning body and bushing 4, regular polygon is could be arranged to, specific side number can be according to required
The size of frictional force, is determined by testing；Frictional force is enough between tuning body and bushing 4, without increasing more frictions
During power, tuning body can also be directly disposed as cylinder type hollow body, frictional force is reached minimum.
Fig. 4 is the structural representation of bushing 4, and as can be seen from the figure the inner surface of bushing 4 is provided with projection, general bushing 4
The raised quantity of inner surface is no less than 3, but this numeral can also change, and in tuning body sheet
When the projection of body can produce enough frictional force, the inwall of bushing 4 can also be not provided with projection, and this implementation can flexibly change
Become, determined by testing, equally, if in the case where the frictional force between tuning body and bushing in itself is enough, also may be used
To be not provided with tuning the projection on pipe, when bushing 4 is equipped with projection with tuning body, clamping schematic diagram therebetween is as schemed
Shown in 6.
The tuning pipe mechanism provided in the present embodiment is applied when on cavity body filter, as shown in figure 5, tuning pipe 5 passes through
The projection and the projection of bushing 4 set on tuning body is fixed on the cover plate 1 of cavity body filter, when needing to be tuned,
It only need to somewhat exert oneself to adjust the height for tuning pipe 5 up and down, after tuning pipe 5 is adjusted into proper height, need to only loose one's grip i.e.
Can, pipe 5 is now tuned due to frictional force caused by projection, is fixed on again on the cover plate of cavity body filter, it is no longer necessary to pass through
External force is tightened pipe 5 is tuned, and reaches time saving and energy saving effect.
