Abstract
The utility model discloses a kind of phase shifter synchronizing moving transmission arm, transmission arm intermediate symmetry arranges two sections of draw-in grooves, and draw-in groove size is consistent with pull bar; Arrange two cylindrical locating pins between two sections of draw-in grooves, hemisphere is made in termination, and the summit of cylindrical locating pin is greater than the vertical range of draw-in groove top to transmission arm to the distance of transmission arm; One group of taper locating pin is respectively established at transmission arm two ends, and tapering is 1 °, and termination is hemisphere, and the summit of taper locating pin is greater than the vertical range of draw-in groove top to transmission arm to the distance of transmission arm.The utility model has the advantage of: this transmission arm does not need screw-nut when assembling, as long as press the draw-in groove clamping pull bar that just can allow and carry, assembling easily, the draw-in groove carried also solves the not positive problem of transmission arm while clamping pull bar, and two cylindrical locating pins between two sections of draw-in grooves can well ensure the synchronism of phase shifter and pull bar.
Description
Technical field
The utility model relates to a kind of phase shifter synchronizing moving transmission arm, especially a kind of Novel transmission arm can fixed with the draw-in groove realization carried.
Background technology
At present, the basic lower decline angle adjustment adopting two phase shifters to realize antenna in dual polarization electrical tilt antenna one-segment, two phase shifters require synchronizing moving.The transmission arm that normally design one is flat, transmission arm two ends are connected with the slipper of two phase shifters respectively, are connected with pull bar by screw-nut.Drive axis drives pull bar to slide thus realizes the synchronous slide of two phase shifters.Such transmission arm and pull bar are fixedly to use screw-nut; be connected with phase shifter slipper again after first transmission can only being fixed with pull bar; assemble cumbersome, transmission arm usually can be made when tightening screw-nut to deflect simultaneously, occurring the different phenomenon of positive and negative bicker degree.
Utility model content
The technical problems to be solved in the utility model is a kind of phase shifter synchronizing moving transmission arm easy to assembly.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of phase shifter synchronizing moving transmission arm, and its innovative point is: comprise the supporting of transmission arm, taper locating pin, draw-in groove, cylindrical locating pin, pull bar, phase shifter and pull bar;
Described transmission arm intermediate symmetry arranges two sections of draw-in grooves, draw-in groove size is consistent with pull bar, two cylindrical locating pins are distributed with on the wide shaft centre line of transmission arm, two cylindrical locating pins are with the center of transmission arm for symmetric points are symmetrical arranged, and one group of taper locating pin is respectively established at the two ends of described transmission arm long axis direction;
Described pull bar is opened two location hole A, the diameter of location hole A is consistent with cylindrical locating pin, and the distance between two location hole A is consistent with the distance between two cylindrical locating pins;
The upper surface of described phase shifter is provided with slide assemblies, and slide assemblies has location hole
band the size of location hole B is consistent with taper locating pin;
Described pull bar all opens spacing hole in the middle of supporting and the size of spacing hole is consistent with pull bar.
Further, described cylindrical locating pin termination is hemisphere, and the summit of cylindrical locating pin is greater than the vertical range of draw-in groove top to transmission arm to the distance of transmission arm.
Further, described taper locating pin tapering is 1 °, and termination is hemisphere, and the summit of taper locating pin is greater than the vertical range of draw-in groove top to transmission arm to the distance of transmission arm.
The utility model has the advantage of: this transmission arm does not need screw-nut when assembling, as long as press the draw-in groove clamping pull bar that just can allow and carry, assembling easily, the draw-in groove carried also solves the not positive problem of transmission arm while clamping pull bar, and two cylindrical locating pins between two sections of draw-in grooves can well ensure the synchronism of phase shifter and pull bar.
