The purpose of the utility model is to provide a kind of cavity body filter and its resonant rod of height adjustable band locking function, purports
The deficiencies in the prior art are being solved, the production cost of filter is reduced, are improving production efficiency.
In order to achieve the above object, the technical scheme adopted by the utility model is a kind of height adjustable band locking function
Resonant rod comprising resonance bar body, the bottom of the resonance bar body attenuate convex and the resonant rod body bottom portion outer
It is provided with self-locking thread on side wall, is threadedly coupled on the self-locking thread there are two self-locking ring, on the outer circumference surface of two self-locking rings
It is provided with external screw thread.
Preferably, the bottom of the resonance bar body is provided with the plum blossom trough for adjusting resonant rod body height.
Preferably, which is overlapped with the central axis of both resonance bar bodies.
Preferably, the cross section of the plum blossom trough is in hexagonal star-shape.
Preferably, the diameter of the resonant rod body bottom portion is 4 ~ 8mm.
A kind of cavity body filter with the resonant rod, including cavity are provided with fulcrum bearing in cavity, open in the fulcrum bearing
Equipped with threaded hole, which is mounted in the fulcrum bearing, in the external screw thread being arranged on two self-locking rings and the threaded hole
The internal screw thread of setting matches.
Compared with prior art, the utility model has the following beneficial effects:
1, flexibility is big, since the resonant rod can adjust height of the resonant rod in cavity body filter by plum blossom trough, therefore
It can be adjusted at any time according to practical debugging, test case；
2, production efficiency is improved, due to having normalized resonant rod, the use of a variety of resonant rods is avoided, reduces because of object
Material obscures the risk for causing production efficiency low；
3, cavity weight is alleviated, Material Cost has been saved, since the resonant rod has self-locking function, therefore is eliminated previous
It is largely used to the screw of fastening resonant rod；
4, install convenient has saved cost of labor, similarly, since the resonant rod has self-locking function, and height is adjustable, therefore
Operator can be assembled easily；
In conclusion the resonant rod of the height adjustable band locking function of the utility model, it is small-sized to have complied with present filter
Change the trend of development, has flexibility big, saved production cost, improved production efficiency.

Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described reality
Applying example is the utility model a part of the embodiment, instead of all the embodiments, based on the embodiments of the present invention, ability
It is practical new to belong to this for domain those of ordinary skill every other embodiment obtained without creative efforts
The range of type protection.
As shown in Figure 1, a kind of resonant rod of height adjustable band locking function comprising resonance bar body 1, the resonant rod sheet
The bottom of body 1, which attenuates, is provided with self-locking thread 2 on convex and 1 bottom of resonance bar body lateral wall, the resonance bar body 1
Bottom be provided with the plum blossom trough 4 for adjusting 1 height of resonance bar body, the center of both the plum blossom trough 4 and resonance bar body 1
Axis is overlapped, and the cross section of the plum blossom trough 4 is in hexagonal star-shape, can also is the other shapes such as pentagon shape, be needed to illustrate herein
It is that convex architecture and the resonance bar body 1 of 1 bottom of resonance bar body are wholely set, self-locking thread 2 is arranged on convex architecture,
The convex architecture is in column type, and diameter 6mm, the flight pitch in self-locking thread is different, is threaded with two on the self-locking thread 2
