Description
Technical field
The utility model is related to wave filter resonance structure application field, more particularly to a kind of spacing for increasing two resonant rods
From eccentric resonance structure.
Background technology
At present, the existing resonance structure of cavity body filter industry is the part of coaxial resonator, resonance plate and resonant rod
It with one heart, in this way can be easy to process, and cost is relatively low.But due to closer to the distance between two resonant rods, safe distance is not achieved
Requirement, until product is made to there is security risk.
Utility model content
To solve the problems, such as above-mentioned background technology, the purpose of this utility model is to provide a kind of eccentric resonance knots
Structure, to achieve the purpose that make distance between its two resonant rod of increasing.
In order to achieve the above objectives, the technical solution of the utility model is as follows：
A kind of bias resonance structure, including cavity and the resonator being arranged in the cavity, the cavity is set as phase
The cube structure to connect, adjacent two cavity share same vertical plane, and inverted U-shaped winged bar is provided on the vertical plane
A winged bar is fixed in seat, the both sides of the winged pole socket respectively, and the resonator is by resonant rod and is fixed on the resonant rod top
Resonance plate forms, and the bottom end of the resonant rod is fixed on the bottom surface of the cavity, is set between the resonant rod and resonance plate
For eccentric shape, the resonator eccentric part of two eccentric shapes is opposite to be installed, and the distance between two resonant rods of eccentric shape are more than concentric
The distance between resonant rod two-by-two of shape.
Preferably, the cavity top end is provided with cover board.
Preferably, the resonant rod is fixed by being arranged on the fixed seat of cavity bottom end.
Preferably, the length end of the winged bar is located at the circle centre position of the resonance plate.
Through the above technical solutions, a kind of eccentric resonance structure provided by the utility model, resonance plate and resonant rod are set
The opposite installation of the eccentric part of eccentric resonator, the structure can not only be increased two when being set to eccentric shape, i.e. decentraction, and installing
Distance before resonant rod has reached the requirement of safe distance, and avoiding product, there are security risks, can also increase winged bar
The useful space of length direction weakens the coupling between two resonators.
Description of the drawings
It 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

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
A kind of eccentric resonance structure provided by the utility model, as shown in Figure 1, including cavity 1 and being arranged on the cavity 1
Interior resonator 2, the cavity 1 are set as the cube structure being connected with each other, and adjacent two cavity 1 shares same vertical plane 3,
Inverted U-shaped winged pole socket 4 is provided on the vertical plane 3, a winged bar 5, the resonator are fixed in the both sides of the winged pole socket 4 respectively
2 are made of resonant rod 6 with the resonance plate 7 for being fixed on 6 top of resonant rod, and the bottom end of the resonant rod 6 is by being arranged on chamber
The fixed seat 8 of 1 bottom end of body is fixed, and eccentric shape is set as between the resonant rod 6 and resonance plate 7, and the resonator 2 of two eccentric shapes is inclined
Center portion split-phase is more than the distance between installation, two resonant rods 6 of eccentric shape the distance between two resonant rods 6 of same heart shaped, institute
The length end for stating winged bar is located at the circle centre position of the resonance plate.
1 top of cavity is provided with cover board 9, and the cover board 9 is fixedly connected by welding or screw with cavity 1.
A kind of bias resonance structure, eccentric shape is set as by resonance plate and resonant rod disclosed in the utility model, i.e., different
The heart, and the opposite installation of the eccentric part of eccentric resonator, the structure can not only be increased into the distance before two resonant rods during installation,
The requirement of safe distance is reached, avoiding product, there are security risks, can also increase effective sky in winged pole length direction
Between, weaken the coupling between two resonators.
The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or new using this practicality
Type.A variety of modifications of these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide range consistent with features of novelty.
