Description
Technical field
The utility model relates to a kind of waveguide junction, specifically sealed rotary joint belongs to waveguide rotation
Joint technical field.
Background technique
Waveguide junction is interface unit important in microwave communication circuit, since antenna is in rotary polarization, waveguide
It is connect between duplexer using loose flange, needs to unscrew on the bolt above loose flange when rotating duplexer every time, wave
It leads between double function devices that leakproofness is particularly poor, is easy to happen signal leakage.
Summary of the invention
In place of the purpose of this utility model is to overcome above-mentioned deficiency, to provide a kind of sealed rotary joint, improve
The leakproofness of waveguide junction, avoids waveguide signal from leaking.
According to technical solution provided by the utility model, sealed rotary joint includes upper waveguide and lower waveguide, feature
Be: the upper downward waveguide end of waveguide surface is equipped with multiple closure gasket grooves, and the lower waveguide waveguide end that faces upward is equipped with and sealing ring slot number
Measure identical sealing strip, in the corresponding multiple closure gasket grooves for being inserted into upper waveguide of multiple sealing strips of lower waveguide, in realizations waveguide with
The sealing of lower waveguide contact end face;Lower waveguide outer ring is equipped with pressing ring, and pressing ring upper end is bolted upper waveguide, lower waveguide by multiple
Deep groove ball bearing there are two being set between pressing ring.
Further, spacer ring is equipped between two deep groove ball bearings, spacer ring is bolted in lower waveguide sidewalls.
Further, pressing ring lower end inside is equipped with postive stop baffle, and lower waveguide is limited in pressing ring by postive stop baffle.
Further, positioned at multiple sealings of a sealing strip of outmost turns and upper waveguide in multiple sealing strips of lower waveguide
Sealing ring is equipped in annular groove between a closure gasket groove of outmost turns, is realized and is sealed by sealing ring.
Compared with the prior art the utility model has the advantage that
The utility model structure is simple, compact, reasonable, stable and reliable in work, improves the leakproofness of waveguide junction,
Waveguide signal is avoided to leak.
Detailed description of the invention
Fig. 1 is the utility model main view.
Description of symbols: waveguide, 3- pressing ring, 4- deep groove ball bearing, 5- spacer ring, 6- sealing ring, 7- under the upper waveguide of 1-, 2-
Closure gasket groove, 8- sealing strip, 9- postive stop baffle.
Specific embodiment
The utility model will be further described in conjunction with the embodiment in attached drawing below:
As shown in Figure 1, the utility model mainly includes upper waveguide 1 and lower waveguide 2, upper waveguide 1 is set 2 one end of waveguide downwards
There are multiple closure gasket grooves 7, lower waveguide 2 faces upward 1 one end of waveguide equipped with sealing strip 8 identical with 7 quantity of closure gasket groove, lower waveguide
In the corresponding multiple closure gasket grooves 7 for being inserted into upper waveguide 1 of 2 multiple sealing strips 8, waveguide 1 and lower 2 contact face of waveguide in realization
Sealing.
Positioned at multiple sealings of a sealing strip 8 of outmost turns and upper waveguide 1 in multiple sealing strips 8 of the lower waveguide 2
Sealing ring 6 is equipped in annular groove 7 between a closure gasket groove 7 of outmost turns, is realized and is sealed by sealing ring 6.
Lower 2 outer ring of waveguide is equipped with pressing ring 3, and 3 upper end of pressing ring is bolted upper waveguide 1, lower waveguide 2 and pressing ring 3 by multiple
Between set there are two deep groove ball bearing 4.
Spacer ring 5 is equipped between described two deep groove ball bearings 4, spacer ring 5 is bolted on lower 2 side wall of waveguide.
3 lower end inside of pressing ring is equipped with postive stop baffle 9, and lower waveguide 2 is limited in pressing ring 3 by postive stop baffle 9.
