Abstract
The utility model provides a deflecting apparatus for TV antenna with electronic control, mainly comprising a controller and a speed reducer. The positive rotation, inversion, and stop of the motor in the speed reducer are controlled by a control switch in the controller. Two worms are arranged on the output shaft of the motor and engage with corresponding worm wheels. The rotation of the motor drives the worm wheels and the output shaft. The output shaft drives a connecting plate and the television antenna through pins. The regulation of the direction of the television antenna at any distance within the controlled ranges is realized. The utility model has the advantages of simple device, reasonable structure and convenient operation. The adjusted direction of the antenna is accurate, and the operators don't directly contact the television antenna.
Description
The utility model proposes indicator device---the television antenna steering gear of control adjustment television antenna on a kind of any distance that is used in the control range.
Existing outdoor television antenna is fixed installation, it can only be aimed at a television transmitting station when mounted.Like this, just poor to the reception of television transmitting station wherein, can't watch sometimes at all, must be to the outdoor sensing of removing to readjust antenna.Especially inconvenience seems.
The purpose of this utility model is the problem at above-mentioned existence, designs on a kind of any distance in can be in a big way control and adjusts television antenna and point to not the directly television antenna steering gear of Contact antenna mode.
Accompanying drawing is a structural representation of the present utility model.
In the accompanying drawing 1 is motor, 2, the 8th, helical gear (or worm gear), the 3, the 10th, side cover, the 4th, casing, the 5th, output shaft, the 6th, pin, the 7th, gusset piece, 9, the 11st, worm screw, the 12nd, controller switches, the 13rd, dry cell.
Below in conjunction with the description of drawings the technical solution of the utility model: structure as shown in drawings. Mainly be made up of controller and reductor two parts, controller is made up of dry cell 13 and gauge tap 12 and shell, and controller switches 12 is motor 1 forward and backward in the control reductors or stop directly. Worm screw 11 directly is housed on the shaft of motor 1, it and helical gear (or using worm gear) 8 mesh, helical gear (or using worm gear) 8 is packed on the axle together with another root worm screw 9, worm screw 9 and helical gear (or using worm gear) 2 engagements, helical gear 2 joins with output shaft 5, output shaft 5 joins by pin 6 and gusset piece 7, and television antenna is to be solidly installed with gusset piece 7. When electric machine rotation is passed to helical gear (or using worm gear) 8 by worm screw 11, drive worm screw 9 with helical gear 8, worm screw 9 is passed to again helical gear (or using worm gear) 2, and helical gear 2 drives output shaft 5, and output shaft 5 is again by pin 6 Drive gusset piece 7 and rotate, and television antenna and gusset piece 7 are solidly installed. Thereby reach the purpose that drives the positive and negative rotation of antenna. Behind motor stalling, because the self-locking characteristic of worm screw has guaranteed the antenna direction unchanged direction. It can any distance control in the design scope adjust the television antenna sensing, and the direct Contact antenna of operator.
Embodiment:
Switch 12 residing positions are circuit open position in the accompanying drawing, and this moment, motor did not change, when switch 12 towards left shown in the accompanying drawing when pushing away, circuit forward connection, driven by motor worm screw 11 turns clockwise.Worm screw 11 drives helical gear (or worm gear) 8 again and turns clockwise, helical gear (or worm gear) 8 drives again with it and turns clockwise with being packed in a worm screw 9 on the axle, worm screw 9 drives helical gear (or worm gear) 2 again and turns clockwise, helical gear (or worm gear) 2 drives output shaft 5 and turns clockwise, and output shaft 5 drives television antenna by pin 6 and gusset piece 7 again and turns clockwise.In the process of antenna rotation, observation television screen simultaneously can see that image will become clearly by fuzzy, and this moment is cut-off switch 12 immediately, so motor stall at once, antenna has been set in the sensing of optimum reception effect.If, because hold inaccurate the opportunity of cut-off switch 12, antenna has turned over head, image is unclear again, so as long as push switch 12 to shown in accompanying drawing right, circuit is just oppositely connected, driven by motor worm screw 11 is rotated counterclockwise, worm screw 11 drives helical gear (or worm gear) 8 again and is rotated counterclockwise, helical gear (or worm gear) 8 drives again with it and is rotated counterclockwise with being packed in a worm screw 9 on the axle, worm screw 9 drives helical gear (or worm gear) 2 again and is rotated counterclockwise, and helical gear (or worm gear) 2 drives output shaft 5 and is rotated counterclockwise, and output shaft 5 drives television antenna by pin 6 and gusset piece 7 again and is rotated counterclockwise.Can cut-off switch 12 when forwarding television image the best to.
Aforesaid operations is all indoor.
Claims (1)
1, the television antenna steering gear of forming by controller and reductor, it is characterized in that control switch 12 controls in the motor 1 controlled device in the reductor, carry out forward and backward or stop, worm screw 11 is housed on the output shaft of motor, it and helical gear (or using worm gear) 8 mesh, helical gear 8 is to be contained on the axle together with another root worm screw 9, worm screw 9 and helical gear (or using worm gear) 2 engagements, helical gear 2 joins with output shaft 5, output shaft 5 joins by pin 6 and gusset piece 7, and television antenna and gusset piece 7 are solidly installed.
