Bar is provided with a plectrum being threadedly coupled with it, and the worm screw connects with plectrum, and can be driven in the drive lower edge of plectrum
Bar slides to engage from different worm gears.
By controlling the rotating speed of drive rod and screw rod, worm screw is often rotated one week and be equal to worm screw along the distance that drive rod is slided
Tooth pitch, so as to worm screw pass through worm gear when interference is not produced to it.
Each worm gear is to that should have a locking device, and the locking device can be made with a spring and one in spring
With the latch segment in the locking hole set on lower insertion worm gear end face.
The both sides of the latch segment are provided with lead-in chamfered, and plectrum can be extruded in moving process by the lead-in chamfered to be locked
Tight block, and it is exited locking hole.
Described locking device, which is provided with, to be used to guide the reciprocating axis of guide of latch segment.
The centre bore section of the worm screw is identical with the section of drive rod, worm screw and drive rod by the projection that matches with
Groove is circumferentially positioned.
The end of the worm screw is in ladder shaft-like, and one end of plectrum coordinates with the shaft shoulder portion of the multi-diameter shaft.
One end of the plectrum has the opening of semi-cylindrical, and the opening and the shaft shoulder portion of worm end multi-diameter shaft coordinate.
Described drive rod and screw rod is each configured with the motor for driving it to rotate.
The beneficial effects of the invention are as follows：Worm screw level and rotary motion are controlled by screw rod and drive rod respectively, by worm screw
It is moved at corresponding worm gear, just the phase shifter that the worm gear is connected can be individually controlled, it is achieved thereby that a transmission
Device drives multiple phase shifters respectively.Its power source need to only control drive rod and screw rod respectively, at most using two motors
Control multiple phase shifters.Compared with original mode, the usage quantity of motor is saved, antenna volume is reduced, and greatly
Reduce cost.

Embodiment
Embodiments of the present invention are illustrated below in conjunction with accompanying drawing.
As illustrated, a kind of phase shifter transmission device, provided with least two worm gears 4 being arranged in a linear, each worm gear 4 is equal
It is connected with phase shifter.Fig. 1 embodiment is controls the embodiment of 6 phase shifters, in order to show that the locking at worm gear rear portion is filled
Put, one of worm gear is eliminated in figure.The drive rod 5 and spiral shell of rotation can be controlled respectively by being provided with along the orientation of worm gear 4
Bar 6.Drive rod 5 and screw rod 6 are parallel to each other, and are installed along with worm gear 4 in a housing.One is provided with drive rod 5
The individual worm screw 3 that slides along but can not rotate against.In order to ensure smooth motion, the centre bore section of the worm screw 3 is with driving
The section of lever 5 is identical.Can using it is any it is applicable by the way of ensure that worm screw 3 does not rotate against with drive rod 5, such as worm screw
Pass through the projection and groove that match with drive rod（Key or keyway）It is circumferentially positioned.Connect on screw rod 6 provided with one with its screw thread
The plectrum 2 connect, the worm screw 3 connects with plectrum 2.Plectrum 2 is provided with the internal thread coordinated with screw rod 6, when screw rod 6 rotates, and dials
Piece 2 can not be rotated due to being limited by worm screw 3, thus by rotating screw rod 6 plectrum 2 can be made to be moved left and right along it, so that
Worm screw 3 is set to slide to engage from different worm gears 4 along drive rod 5 under the drive of plectrum 2.Can be by any feasible
Mode make plectrum 2 drive worm screw 3 while do not influence it to rotate.Bearing, the end of worm screw 3 are for example set on plectrum 2
It is placed in bearing.Or as shown in Figure 4,5, it is in ladder shaft-like, one end of plectrum 2 and the ladder that the end of worm screw 3, which is arranged to,
The shaft shoulder portion of axle coordinates.Further, one end of plectrum 2 can be arranged to the opening with semi-cylindrical, the opening with
The shaft shoulder portion of the end multi-diameter shaft of worm screw 3 coordinates.
After worm screw 3, which slides into, to be engaged and stop with one of worm gear 4, by rotary worm 3 worm gear 4 can be driven to revolve
Turn, and then corresponding phase shifter is adjusted.Select the worm gear 4 to be adjusted when, worm screw 3 be typically passed through it is several be not required to adjust
Whole worm gear.In order that worm screw 3 by when not to these without adjustment worm gears produce interference, can be by controlling drive rod
5 and the rotating speed of screw rod 6, worm screw 3 is often rotated the tooth pitch for being equal to worm screw 3 for one week along the distance that drive rod 5 is slided.Its principle exists
When the static engagement of, it is assumed that worm and wheel, worm screw every revolution worm gear turns over a tooth, i.e. worm and gear relative displacement one
Tooth pitch P1, if opposite direction makes worm screw move one, apart from P1, worm gear can be motionless with remains stationary, so that worm screw can be realized
By any worm gear without producing interference.The distance that worm screw can be controlled to move in the following way.First way：By setting
Count drive screw 6 pitch be P1, drive screw 6 turn around then worm screw movement be P1.The second way：If drive screw 6
Pitch is not equal to P1, then can be by adjusting stepper motor rotating speed, and it is P1 to make worm screw amount of movement.
When not adjusting phase shifter, in order to prevent worm gear wheel, a locking device can be configured to each worm gear, should
Locking device has the lock in a spring 8 and a locking hole that can be set under the effect of spring 8 on the insertion end face of worm gear 4
Tight block 7.The shape of latch segment and locking hole can be arranged as required to, as long as its function can be realized, such as at worm gear end
The locking hole for the circular hole that is circularly and evenly distributed on face, protrusion is set on latch segment, the cylinder in locking hole is inserted into
Shape is raised.Further, lead-in chamfered 9 is provided with the both sides of the latch segment 7, plectrum 2 can be by this in moving process
Lead-in chamfered extrudes latch segment 7, and it is exited locking hole, so that during worm movement to the position engaged with worm gear, accordingly
Worm gear automatic unlocking.The locking device also can be set for guiding the reciprocating axis of guide of latch segment 7, to ensure its essence
Positive motion is made.
In the transmission device of the present invention, 6 need of drive rod 5 and screw rod are respectively provided for driving the motor of its rotation
Realize the control to multiple phase shifters.The embodiment of 6 phase shifters of control is given shown in Fig. 1, Fig. 2, according to actual needs,
It is settable 5,8, even more many phase shifters.
