Requisite instrument when tuning sleeve is the filter debugging.
In traditional tuning sleeve, every a tuning screw just needs a tuning sleeve, does not want different tuning sleeves for different tuning screws and matches, and this greatly reduces the utilance of tuning sleeve.The material selection stainless steel 303 of tuning sleeve, the stainless steel intensity and toughness is all good not, while using for a long time pullover interior hexagonal to be out of shape to use, skids or chipping is scrapped.Just can not use after the higher and pullover chipping of the manufacturing cost of this sleeve, cause the waste of material, increase use cost.
The utility model content
The purpose of this utility model is to provide a kind of tuning sleeve assembly, is intended to solve tuning sleeve and the matching used problem of tuning screw in prior art.
The utility model is to realize like this, a kind of tuning sleeve assembly, for the resonance frequency of regulating coaxial cavity filter, described tuning sleeve assembly comprises handle, coordinate be used in conjunction with described tuning screw pullover with described handle and be fixedly connected with described handle and described pullover fixture, described handle comprise be convenient to grip part that hand grips and along described grip part outstanding with the described pullover connecting portion be connected.
Further, the outer surface of described grip part is provided with annular knurl.
Further, describedly pulloverly comprise the stiff end that coordinates with described connecting portion and, along the outstanding adjusting rod extended to coordinate with described tuning screw of described stiff end, described fixture coordinates with described connecting portion and described stiff end.
Further, described fixture is trip bolt, pin for suppressing metal or latch.
Further, described connecting portion is provided with the host cavity of accommodating described stiff end and the fixing hole coordinated with described fixture, and described stiff end is provided with the draw-in groove of the described fixture of restriction.
Further, described connecting portion is provided with the first plane, the chamber wall surface that described the first plane is described host cavity, and described stiff end is provided with the second plane cooperatively interacted with described the first plane.
The utility model also provides a kind of coaxial cavity filter, comprises above-mentioned tuning sleeve assembly.
The tuning sleeve assembly that the utility model provides coordinates by pullover and handle, in use, by changing the pullover of different model, with the tuning screw from different, coordinate, and without changing and this pullover handle coordinated, simple to operate, easy to use, need the problem according to the whole tuning sleeve assembly of model replacing of tuning screw in avoiding using.
