Description
Technical field
The utility model relates to technical field of communication equipment, in particular to a kind of filter of plastic deformation tuning lid.
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 filter adjusts distance of the tuning cover board to resonant rod, this design structure by adjusting screw rod
Complexity, production efficiency are low.So need a kind of structure simpler, the filter being readily produced.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of filter of plastic deformation tuning lid, a kind of modeling
Property deformation tuning lid filter, save adjusting screw rod, structure is simple, is readily produced.
To solve the above-mentioned problems, the utility model provides a kind of filter of plastic deformation tuning lid, including cavity, humorous
Shake bar, tuning lid, cover board screw, tuning plug screw, and the tuning is covered with resonance cover board, and the centre of resonance cover board is equipped with plasticity
Control key, the resonance cover board is milling thin plate, and has plastically deformed performance；The centre in resonant rod portion in the cavity,
It is fixed by tuning plug screw, the tuning is covered in the top of cavity, is fixed by cover board screw.
It further says, the percussion or up hook drawing by plasticity control key changes resonance cover board to resonance
The distance of bar.
It further says, the plasticity control key can be a kind of T-shaped key.
It further says, the plasticity control key can be a kind of circular ring shape key, and there are three lug bosses for tool.
In use, since resonance cover board is milling thin plate, and there is plastically deformed performance, by being struck to plasticity control key
Hit or up hook drawing, the distance of change resonance cover board to resonant rod.
The beneficial effects of the utility model are：Traditional adjusting screw rod that is equipped with is saved, the plasticity of tuning cover board is only passed through
Deformation changes tuning cover board to the distance of resonant rod, and structure is simple, is readily produced.

Centre of the resonant rod 2 inside cavity 1 is stated, fixed by tuning plug screw 5, the tuning lid 3 passes through in the top of cavity 1
Cover board screw 4 is fixed.
Specifically：Since resonance cover board 30 is milling thin plate, and there is plastically deformed performance, by plasticity control key 31
Percussion or up hook draw, change resonance cover board 30 arrive resonant rod 2 distance.
Refering to shown in attached drawing 1, Fig. 2, Fig. 3, Fig. 4, the percussion or up hook drawing by plasticity control key 31 changes
Become the distance that resonance cover board 30 arrives resonant rod 2.
Refering to shown in attached drawing 1, Fig. 2, the plasticity control key 31 can be a kind of T-shaped key.
Refering to shown in attached drawing 3, Fig. 4, the plasticity control key 31 can be a kind of circular ring shape key, and there are three lug bosses for tool
311。
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.
