Abstract
The utility model relates to a controllable steering gear, which is a controllable device of an outdoor antenna which is able to be operated indoors. The pulsed current of utility model is generated by an oscillating circuit. The conducting and cutting of the current which flows through an electromagnet coil is controlled by the oscillating circuit. Therefore, an armature is attracted or released. A carrier rod pushes a ratchet wheel on the armature, and drives an antenna axis rotate. The aim of regulating the steering of the outdoor antenna indoors is achieved.
Description
The utility model is a kind of steering control device of relevant outdoor television antenna, can operate indoor.
Existing exterior aerial mainly is made up of antenna and support.After this antenna installed, it just was fixed up to direction, just can not adjust direction at any time as required in the process of televiewing, and made the reception of television set be subjected to influence.
The utility model be to provide a kind of can be at the controlled transfer of the outdoor television antenna of in-house operation.But the operator sees on the limit TV limit and regulates the direction of antenna, to obtain the optimum reception effect.
The utility model comprises that a housing and a rotating vertical rotation axis that is fixed with electromagnet, armature etc. reaches the ratchet of interlock with it, and the power that wherein orders about the antenna rotation is not to adopt conventional motor, but the employing electromagnet.The break-make of control electromagnet current, the adhesive that promptly produces armature---restoring action is established a push rod at the suitable position of armature, and there is ratchet the push rod front portion, then just can the corresponding ratchet that pushes, ratchet links with rotating shaft, and antenna is one-directional rotation intermittently just.Because antenna has constant weight, add outdoorly can be subjected to windage at any time, push ratchet by push rod and directly drive antenna many difficulties are arranged.Therefore need to increase a gear between antenna and ratchet, this can use gear train, also available scroll bar worm gear drive.Adopt this a kind of transmission in back can avoid the influence of wind.Use the button control electromagnet, whenever push once, ratchet can only rotate little lattice, and this makes troubles to use.So increase an oscillating circuit on the line again, when pressing button, can produce pulse current continuously, push ratchet and rotate, thereby, just can reach the purpose of control antenna rotational angle as long as the button time is pressed in control.It line-spacing television set has certain distance, uses two control lines can improve user's burden separately, and the utility model is realized with feeder.Specific practice is to increase a TV set aerial plug, and two chokes of polyphone are in parallel with oscillating circuit on plug, just can realize this scheme.
This steering gear can obtain the best and watch effect in the direction of indoor any adjustment exterior aerial; It compares safety without alternating current; It replaces control line with feeder line, reduces use cost, and its advantage is tangible.
Below in conjunction with accompanying drawing most preferred embodiment of the present utility model being done one describes.
Fig. 1 is a schematic diagram of the present utility model, and Fig. 2 is a vertical view of the present utility model, and Fig. 3 is a clapp oscillator circuit diagram of the present utility model.
With reference to Fig. 1, Fig. 2, electromagnet (1) is fixed on the housing (9), and armature (2) is vertical to be installed, and its lower end and spring leaf connect (spring leaf is then fixed in housing).The upper end is become flexible with bolt and push rod (3) and is connect, and the ratchet of push rod (3) then becomes matching relationship with ratchet (4), and ratchet is meshed with turbine (6) with the coaxial interlock of scroll bar (5), scroll bar, turbine (6) and vertical rotation axis (7) moved in coaxial that is with antenna.With reference to Fig. 3, electromagnet coil J is controlled by oscillating circuit, push button K
1The starting of oscillation voluntarily of back circuit, armature (2) is make contact switch J when promoting push rod (3)
1, capacitor C discharge at this moment, coil J dams, and armature discharges, contact switch J
1Turn-off capacitor C charging, coil J water conservancy diversion, armature adhesive.Circulation is carried out like this, becomes the action that continues of electromagnet.R among the figure

3Be unidirectional breakover element, in order to the protection triode; Choke GZL can hinder the influence of high-frequency signal to switching circuit.Armature (2) is driven push rod (3) and produces an active force left by adhesive, promotes ratchet (4) and rotates counterclockwise, and the ratchet revolution moves a week, and turbine then rotates a tooth.The antenna required time of circle of rotating was controlled within two minutes.
The utility model divides outdoor and indoor two parts manufacturing.Indoor section (frame of broken lines of Fig. 3 in part) is assembled in the capsule (plug is suitably pulled out) with 6 volts of DC power supply, button, feeder head with the plug of two chokes; In addition oscillating circuit is made printed circuit board (PCB) and be installed in the housing, form outdoor section.For rainproof, also can add a rain-proof cover, be fixed on the vertical rotation axis in company with rotating.
Claims (4)
1, a kind of outdoor television antenna steering controller, comprise that one has the housing (9) of electromagnet (1), armature (2) and a rotating vertical rotation axis (7) to reach the ratchet (4) of interlock with it, it is characterized in that going up the loosening push rod (3) that is associated with at armature (2), the push rod front portion has ratchet, and ratchet becomes matching relationship with ratchet.
2, by the described controller of claim 1, it is characterized in that having on the ratchet (4) a coaxial scroll bar (5), a coaxial turbine (6) is arranged on the vertical rotation axis (7), scroll bar and turbine are meshing with each other.
3, by claim 1 or 2 described controllers, it is characterized in that the coil of electromagnet (1) is controlled by an oscillating circuit.
4,, it is characterized in that being parallel with on the oscillating circuit TV set aerial plug, centre two chokes of contacting respectively by the described controller of claim 3.
