Abstract
The utility model provides a DC remote control turning TV receiving aerial whose direction converter adopts the 180 DEG combination of two planet gears and which proceeds a speed reducing transmission by three-stage superimposition, an internal gear and a gear frame are respectively provided with a positioning shaft and a positioning hole, and accurate centering ensures a good mesh of the gear. The inner wall of a casing is provided with three ribs, and the gears combination of three-stage superposition is pushed in to position and fix. A toggle switch and two diodes which have the same direction and which are connected in parallel are used as spacing and turning to make the antenna do 360 DEG forward and reverse rotation. The direction converter is matched with a 'Z'-shaped support frame and a log-periodic antenna which is made by aluminum tube dipoles; the 'Z'-shaped support frame and the log-periodic antenna are connected by a feed line and a controller whose power supply is dry cells to make one DC remote control turning TV receiving antenna.
Description
The utility model belongs to the television reception field.
Television set has entered huge numbers of families at present, and TV station also constantly increases.In order to watch the TV programme of far and near variant direction better, the remote control position controlled rotary antenna has obtained extensive use.
Commercially available remote control position controlled rotary antenna has two big classes: a class adopts and exchanges steering gear, the steering gear of another kind of employing direct current.Adopt the safe, convenient of direct current steering gear, thereby use wider because of it.
The present direct current remote control position controlled rotary antenna (is 87206685 as the patent No.) that uses, its steering gear mostly is the floated transmission of multi-stage superimposed tri-star wheel, complex structure, poor reliability, and commutate with series diode, diode seals in power supply circuits during rotation, 0.7 volt of step-down is arranged, pivoting moment is reduced, must use 6 volts of (four joint C-size batteries) above power supplys, the power utilization rate is low, and loss is fast.
The utility model is exactly for simplified structure, improves reliability, and the performance of improvement and raising direct current position controlled rotary antenna proposes.
The purpose of this utility model is achieved in that in plastic casing, and direct current micromotor is installed, the multistage planet wheel decelerator, and spacing reversing arrangement is formed the direct current steering gear.Install a secondary logarithm periodic antenna in the steering gear additional, be connected with controller, can form one pair of direct current remote control and turn to television receiving antenna with feeder line.
Accompanying drawing 1 is the profile of direct current steering gear, and accompanying drawing 2 is steering gear electrical schematic diagrams, and accompanying drawing 3 is that the direct current remote control turns to the television receiving antenna overall pattern, and accompanying drawing 4 is fixed supports that the socket antenna oscillator is used.
In the accompanying drawing, 1, rotating shaft, 2, split washer, 3, toggle switch, 4, shell, 5 tooth rests, 6, gear shaft, 7, split washer (Φ 2), 8, tooth rest, 9, planetary gear, 10, packing ring, 11, wiring board, 12, the tooth axle, 13, motor, 14, screw, 15, rubber washer, 16, tapping screw, 17, nut (M8), 18, base, 19, spring shim, 20, bolt, 21 lead-in wires, 22, lead-in wire, 23, diode, 24, the internal gear I, 25, the internal gear II, 26, reverse wheel, 27, plastic washer, 28, screw, 29, steering gear, 30, antenna, 31, feeder line, 32, controller, 33, plug special, 34, the oscillator support.
Housing is made up of shell, base, screw bolt and nut, rises to install and fix and supporting role.
Decelerator is by internal gear, planetary gear, and three grades of stack combinations of tooth rest and tooth axle form.The design adopts two planetary gear structures of 180 degree.In order to make central gear (with the tooth rest one) self-centering, so on internal gear and tooth rest, increased locating shaft and location hole.
Three grades of combination stacks of the design are made buffer by three rib location (can increase outer cover intensity like this and simplify assembly technology again) on the outer casing inner wall with rubber washer, whole reducing mechanism are compressed (seeing figure one) with base.This structure is not only saved trip bolt, and simplifies assembly technology, can also make its autobalance gear meshing at different levels to gears at different levels because of the deviation in manufacture process compensates.
The course of work of this decelerator is as follows: press button on the controller, and energized, electrical micro-machine rotates.The tooth axle drives the two planetary gears rotation of the first order on the electrical micro-machine, and two planetary gear rotations drive the rotation of first order tooth rest, and the tooth axle on the first order tooth rest drives second level planetary gear rotation again, and the like.The afterbody tooth rest drives the rotating shaft rotation, and rotating shaft just drives antenna and slowly rotates.
This steering gear can rotate freely by 360 degree, and toggle switch is adopted in spacing commutation.The diode that is attempted by in the same way on the toggle switch only works the stream effect that continues when commutation, diode is not had 0.7 volt of pressure drop by short circuit during normal rotation, and the power utilization rate improves greatly, thereby can adopt low voltage.The shell of steering gear adopts ABS plastic, and gear adopts the nylon 1010 with self-lubrication performance to make, so the lubricating fluid of need not annotating.Antenna is compound logarithm periodic antenna.This antenna bandwidth, gain is high.The oscillator support adopts " Z " type structure, modern design, sound construction.
Claims (3)
1, a kind of Novel DC remote control turns to television receiving antenna, and multistage planet wheel stack combinations location deceleration transmission is adopted in steering gear; Make stop and commutator with toggle switch and diode, it is characterized in that: planetary gear is the two-wheeled transmission that 180 degree are placed, and locating shaft and location hole are arranged on internal gear and the tooth rest.
2, television receiving antenna according to claim 1 is characterized in that: two commutation fly-wheel diodes (are both negative or positive electrode) in the same way and are attempted by on the toggle switch.
