The waveguide transmission structure includes a first assembly and a second assembly, the first assembly is composed of an orthogonal membrane coupler and a movable link, and the second assembly is composed of a filter and an LNB. The waveguide transmission structure is characterized in that the movable link is sleeved on one end of the orthogonal membrane coupler trough a bearing, the upper portion of the filter and the axial direction position of the orthogonal membrane coupler are provided with through holes corresponding to each other, the orthogonal membrane coupler is fixedly connected to the filter through screws, a lower protruding portion of the filter is provided with a flange, the flange and the lower portion of the LNB are provided with through holes corresponding to each other, the LNB is fixedly connected to the lower portion of the filter through screws, and the filter and the LNB form a closed shape encircling the orthogonal membrane coupler.
Description
Technical field
The utility model relates to a kind of waveguide structure, relates in particular to waveguide transmission structure in a kind of portable satellite station and communication in moving system.
Background technology
Traditional portable satellite station waveguide structure is by quadrature film coupler, filter, activity link and low noise block downconverter (LNB) form, filter, LNB assembly axially with the axially parallel of quadrature film coupler, and connect in turn.Due to filter, the axial dimension of LNB assembly is long, causes waveguide structure to take up space larger.So, be unfavorable for the installation of complete machine structure, safeguard loaded down with trivial detailsly, be more unfavorable for miniaturization and the portability of complete machine structure, and affect the visual effect of complete machine structure overall appearance.Waveguide mechanism takes up space greatly, correspondingly makes the huge of its installed part (integrated support arm) change, has increased the difficulty of machining.
Therefore, those skilled in the art is devoted to develop a kind of taken up space little, easy for installation, is beneficial to the waveguide structure that complete machine is safeguarded and miniaturized structure designs.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of taken up space little, easy for installation, is beneficial to the waveguide structure that complete machine is safeguarded and miniaturized structure designs.
For achieving the above object, the utility model provides a kind of waveguide structure, comprise the first sub-assembly and the second sub-assembly, described the first sub-assembly is comprised of quadrature film coupler and activity link, described the second sub-assembly is comprised of filter and LNB, it is characterized in that activity link is connected on one end of quadrature film coupler by bearing holder (housing, cover); There is the through hole of mutual correspondence at the axial position of the top of described filter and described quadrature film coupler, by screw, described quadrature film coupler is fixedly connected on described filter, the outstanding position, bottom of described filter is provided with ring flange, the through hole of mutual correspondence is arranged on described ring flange and the bottom of described LNB, by screw, described LNB is fixedly connected on to the bottom of described filter, described filter and described LNB formation are close-shaped around described quadrature film coupler.
Further, described LNB refers to low noise block downconverter.
Further, the front end of described quadrature film coupler is nose circle waveguide.
Further, described quadrature film coupler, described filter and described LNB make the as a whole axle around described quadrature film coupler and rotate up.
Further, described waveguide structure size is in the axial direction described nose circle waveguide to the length of described activity link.
This structural advantages of technique effect is: reduced waveguide structure and taken up space, reduced the difficulty of its machining, also strengthened the attractive in appearance of monnolithic case simultaneously.The most important thing is that this waveguide structure can be general on communication in moving, because communication in moving system is very harsh to the requirement of complete machine structure overall dimension (miniaturization), reducing that waveguide machine structure takes up space is very favorable undoubtedly concerning communication in moving system.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to understand fully the purpose of this utility model, feature and effect.
Accompanying drawing explanation
Fig. 1 is the waveguide structural representation of a preferred embodiment of the present utility model.
Number in the figure explanation
1-LNB; 2-filter; 3-activity link; 4-quadrature film coupler.
Embodiment
A structure, comprises the first sub-assembly and the second sub-assembly, and the first sub-assembly is comprised of quadrature film coupler 4 and activity link 3, and the second sub-assembly is comprised of filter 2 and LNB1, and activity link 3 is connected on one end of quadrature film coupler 4 by bearing holder (housing, cover); There is the through hole of mutual correspondence at the axial position of the top of filter 2 and described quadrature film coupler 4, by screw, quadrature film coupler 4 is fixedly connected on filter 2, the outstanding position, bottom of filter 2 is provided with ring flange, the through hole of mutual correspondence is arranged on ring flange and the bottom of LNB1, by screw, LNB1 is fixedly connected on to the bottom of filter 2, filter 2 and LNB1 formation are close-shaped around quadrature film coupler.Wherein, LNB1 refers to low noise block downconverter.The front end of quadrature film coupler 4 is nose circle waveguides.Like this, quadrature film coupler 4, filter 2 and LNB1 make the as a whole axle around quadrature film coupler 4 and rotate up.Waveguide structure size is in the axial direction nose circle waveguide to the length of activity link 3, and size significantly reduces.
More than describe preferred embodiment of the present utility model in detail.The ordinary skill that should be appreciated that this area just can be made many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection range by claims.
