The tuning pipe includes tuning body and flange face, and the flange face is fixed on the side of tuning body, the tune
Humorous body is connected with bushing, is connected on bushing by flange face.
The tuning body is hollow.
The flange face is hexagon.
The bushing includes bush body, bushing top surface and projection, and the bushing top surface is fixed on the side of bush body,
The raised inwall for being located at bush body, the bush body are connected with the cover plate of tuning pipe and cavity body filter respectively, are led to
Cross bushing top surface to be connected on the cover plate of cavity body filter and by raised fixed.
The raised quantity is no less than 3.
The bushing top surface is circle.
The bushing top surface is welded on the cover plate of cavity body filter.
Compared with prior art, this utility model has the advantages that：
(1) the projection locking immediately that Gutron is crossed on bushing is tuned, additional lock power need not be reused, assembling regular worker is reduced
Sequence, it is easy to use.
(2) due to by the raised and unconventional nut check on bushing, therefore tune that pipe is upper need not to arrange thread, adjust
Humorous pipe does not have sophisticated burr yet, without sliding tooth risk.
(3) when tuning pipe is debugged up and down, only friction is contacted with raised generation of bushing inwall, rubbing surface is little,
Reduce the risk for producing that chip enters cavity.
(4) tuning pipe is hollow-core construction, lightweight, is conducive to radio frequency apparatus lightweight.
(5) as tuning pipe need not arrange thread, therefore surface smoothness is high, is adapted to high-frequency high-power and high intermodulation
Application.
(6) bushing is welded on the cover plate of cavity body filter, and bushing top surface is circle, on cavity filter cover board
Opening matches, it is ensured that bushing will not fall off, and security performance is high.
(7) top for tuning pipe is hexagon flange face, is connected in above bushing, and hexagon carrys out snap effect compared with circle
More preferably, it is not susceptible to slide, has ensured that tuning pipe can be locked.
(8) raised quantity is no less than 3, it is ensured that tuning pipe is difficult to slide.

Specific embodiment
This utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with this utility model
Implemented premised on technical scheme, given detailed embodiment and specific operating process, but guarantor of the present utility model
Shield scope 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 matched 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 after first unscrewing tuning screw 3 to suitable height, then tightens nut 2 and fix tune
Humorous screw 3, reaches the purpose of tuning.This mode not only wastes time and energy, and tuning screw 3 is susceptible to slide tooth, while turning
During dynamic, tuning screw 3 easily produces chip and enters in cavity body filter, and the cover plate 1 of cavity body filter is also susceptible to should
Force deformation, the structural representation of its cover plate 1 are as shown in Figure 6.
The tuning pipe mechanism provided in being illustrated in figure 2 the present embodiment, the mechanism include tuning pipe and bushing, and bushing is located at
On the cover plate of cavity body filter, it is connected with tuning pipe and cavity body filter respectively, tuning Gutron is crossed bushing and is connected in cavity filtering
On the cover plate of device.
As shown in figure 3, tuning pipe includes tuning body and flange face, flange face is fixed on the side of tuning body, tuning
Body is connected with bushing, is connected on bushing by flange face.Tuning body is hollow.Flange face is hexagon.
