Description
Technical field
The utility model relates to technical field of communication equipment, in particular to a kind of filter for being centrifuged tuned resonating cavity.
Background technique
Filter plays an important role in the processing of electronic signal always, it have allow useful signal as far as possible
No failure passes through, the function of the failure as big as possible to garbage signal.Filter is widely used in the communications such as radio frequency, microwave neck
Domain, wherein traditional metal coaxial cavity filter technical maturity, most widely used.It is fast with microwave radio commu system
Speed development, the resource of frequency range it is in short supply, the requirement received to the transmitting loose joint of signal is also higher and higher, to the performance and volume of filter
Propose increasingly higher demands.
Conventional filter is single-chamber tuning manner at present, and is center capacitive coupling design method, as shown in figure 3, lid
Distance from bottom is tuning distance a in plate to resonant rod cylinder, since conventional filter is by the height of erecting bed, fastening screw head
Limitation is suitble to use in the equipment of 600Mhz or more so tuning distance a is shorter；But for the equipment of low-frequency range, just
It is not available；So needing a kind of tuning distance a long, it is suitble to the filter used in low-frequency range equipment.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of filter of rotary tuning self-locking structure, the one kind
It is centrifuged the filter of tuned resonating cavity, is improved using exocentric structure, distance is tuned, is suitble to use in the equipment of low-frequency range.
To solve the above-mentioned problems, the utility model provides a kind of filter for being centrifuged tuned resonating cavity, which is characterized in that
Including cavity, tuning cover board, resonant rod, two tuning screws, two nuts, fixing screws, multiple cover screws, the cavity
Interior centre is equipped with resonant rod bracket；The resonant rod is set there are two cylinder, fixed supported hole, and the fixed supported hole is in two cylinders
Between body；The resonant rod in the cavity, fix on resonant rod bracket, and with fixing screws by the fixation supported hole of resonant rod
Firmly；Tuning cover board is covered above the cavity, and is fixed with multiple cover screws；Described two tuning screws pass through tuning lid
Plate, and each cylinder on each tuning screw alignment resonant rod；Each nut is above each tuning screw；The tune
The distance of the lower section of humorous cover board to cylinder body bottom is tuning distance a.
Furtherly, the tuning distance a, more compared with tuning distance a produced by only single cylinder resonant rod filter
It is long.
Furtherly, described since tuning distance a is longer, so can be used in low-frequency range equipment.
In use, since resonant rod is set, there are two cylinders, fixed supported hole, and fix supported hole between two cylinders,
So its tune distance a, not by the erecting bed at resonant rod center, the height of fastening screw head and limit, compared with only single cylinder
Tuning distance a produced by body resonant rod filter is longer；Since tuning distance a is longer, so can be used in low-frequency range equipment.
The utility model has the beneficial effects that: the design is improved using exocentric structure, there are two cylinder, debugging for resonant rod
Screw is installed in resonant rod centrfugal stretching hole, so that tuning screw is not by the erecting bed at resonant rod center, the height of fastening screw head
It spends and limits, compared with the filter that conventional i.e. resonant rod only has single cylinder, tune apart from longer；Since tuning is apart from longer,
So can be used in low-frequency range equipment.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, and the attached drawing in describing is that this is practical
Novel some embodiments to those skilled in the art without creative efforts, can be with
Other accompanying drawings can also be obtained according to these attached drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is Fig. 1 schematic top plan view.
Fig. 3 is the structural schematic diagram of conventional filter.
Below with reference to embodiment, and referring to attached drawing, the realization of the utility model aim, functional characteristics and advantage are made into one
Walk explanation.
Specific embodiment
In order to keep the purposes, technical schemes and advantages of utility model clearer, implement below in conjunction with the utility model
Attached drawing in example, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described reality
Applying example is utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, this field
It is practical new to belong to this for those of ordinary skill's every other embodiment obtained without making creative work
The range of type protection.
Embodiment one:
Refering to shown in attached drawing 1, Fig. 2, Fig. 3, a kind of filter being centrifuged tuned resonating cavity, including cavity 1, tuning are covered
Plate 2, resonant rod 3, two tuning screw 4, two nut 5, fixing screws 6, multiple cover screws 7, it is intermediate in the cavity 1
Equipped with resonant rod bracket 11；The resonant rod 3 is set there are two cylinder 31, fixed supported hole 32, and the fixed supported hole 32 is two
Between a cylinder 31；The resonant rod 3 in cavity 1, use on resonant rod bracket 11 by the fixation supported hole 32 of resonant rod 3
Fixing screws 6 are fixed；Tuning cover board 2 is covered above the cavity 1, and is fixed with multiple cover screws 7；Described two tune
Humorous screw 4 passes through tuning cover board 2, and each tuning screw 4 is directed at each cylinder 31 on resonant rod 3；Each nut 5 exists
Each 4 top of tuning screw；The distance of lower section to 31 bottom of cylinder of the tuning cover board 2 is tuning distance a.
Specifically: since resonant rod 3 is set, there are two cylinders 31, fixed supported hole 32, and fixed supported hole 32 is in two cylinders
Between body 31, thus its tune distance a, not by the erecting bed at resonant rod center, the height of fastening screw head and limit, compared with only
There is tuning distance a produced by single cylinder resonant rod filter longer；Since tuning distance a is longer, so can be set in low-frequency range
Standby middle use.
Refering to shown in attached drawing 1, Fig. 2, Fig. 3, the tuning distance a is produced compared with only single cylinder resonant rod filter
Raw tuning distance a is longer.
It is described since tuning distance a is longer refering to shown in attached drawing 1, Fig. 2, so can be used in low-frequency range equipment.
Above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although referring to aforementioned reality
Example is applied the utility model is described in detail, those skilled in the art should understand that: it still can be to preceding
Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features, and these
Modifications or substitutions, the spirit and model of various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
It encloses.
