Abstract

The utility model discloses an additional device for remote control a color TV, comprising hand-hold remote control operation portion, a power supply switching control portion and the power supply portion of the additional device for remote control a color TV. The additional device for remote control a color TV is characterized in that the additional device for remote control a color TV is provided with a channel selecting control portion which uses an electric magnet to drive a push rod. The additional device for remote control a color TV can be used for a color TV which does not have remote control functions, and makes the color TV increase the channel selecting remote control function and the power supply switching remote control function.

Description

Additional divice for remote control of color TV

The utility model relates to a kind of remote control of colour television set attachment device, does not possess the color television set of distant control function applicable to itself.

The color television set of more existing kinds has distant control function, also has some kinds itself not have distant control function, make the latter increase the distant control function the same with the former, need do more repacking to the latter's circuit and structure, implements to acquire a certain degree of difficulty.

The purpose of this utility model is otherwise the circuit and the structure of changing television set use simple attachment device, makes the television set increase channel selection itself that do not possess distant control function and the distant control function of mains switch.

Remote control of colour television set attachment device provided by the utility model comprises the hand-held remote control operation part, the mains switch control section, and this device power unit is characterized in that being provided with the channel selection control section with the solenoid actuated push rod.

Remote control of colour television set attachment device provided by the utility model, has advantage of simple structure, the channel selection control section of this device is connected with television set with geometrical clamp or fixed mount, when not using this device, can separate easily, television set promptly restores to the original state, thus easy to use, and the utility model provides practical remote control attachment device for the user.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the embodiment schematic diagram of remote control attachment device of the present utility model;

Fig. 2 is the channel selection control section schematic diagram of remote control attachment device of the present utility model;

Fig. 3 is the principle calcspar of the embodiment of remote control attachment device of the present utility model;

Fig. 4 is the schematic circuit of the embodiment of remote control attachment device of the present utility model;

Fig. 5 is another embodiment schematic diagram of remote control attachment device of the present utility model.

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4,1 is the channel selection control section among the figure, it comprises that 8 are electromagnet, and 9 is push rod, and 10 is stage clip, 11 are the ad hoc elastic fixing clip that locating notch is arranged, 11 material is the ABS engineering plastics, and 12 is the geometrical clamp of adjustable elastic, and 12 material is an elastic copper sheet, 13 is the viscosity adhesive plaster, and 14 is screw.The shell of this part is rectangular sealing plastic casing.Several equidistant holes, garden of arranging are linearly arranged on the bottom surface of box, and the spacing in hole is corresponding with the spacing of the button of TV channel preselector, and the push rod 9 of garden cylindricality is arranged in each hole.The inside of box is by some covers being housed by electromagnet 8, the actuating mechanism that push rod 9 and stage clip 10 are formed, actuating mechanism is according to the positional alignment in hole, garden, electromagnet 8 is near push rod 9, and the action iron plate of electromagnet 8 just in time is pressed in push rod 9 tops, and stage clip 10 is enclosed within on the push rod 9, when electromagnet 8 energisings, its action iron plate promotes to stretch out the button of pressing the TV channel preselector the hole, garden of push rod 9 from the box bottom surface, and during electromagnet 8 outages, stage clip 10 resets actuating mechanism.The left surface of box with screw by 2 geometrical clamps 11 that have only locating notch are housed, it also can with box integral molded plastic moulding together.By the geometrical clamp 12 that 2 adjustable elastics are housed, its profile is the sheet strip to the right flank of box with screw, and its leading section is provided with viscosity adhesive plaster 13.2 pairs of clips of geometrical clamp 11 and geometrical clamp 12 relative formations utilize these 2 pairs of clips that box is installed in the dead ahead of TV channel preselector, make push rod 9 just in time aim at the button of TV channel preselector.Adjust the distance of 2 pairs of clips and the television set that elasticity can adapt to different model.Above-mentioned actuating mechanism can be 2 to 12 covers, and present embodiment is selected 4 covers for use, receives the quantity of TV station according to desire and decides.

2 is the mains switch control section among the figure, and it comprises this device power unit, comprises that also 4 are supply socket, for being inserted by the attaching plug of the television set of remote control.

3 is the hand-held remote control operation part among the figure, and it comprises that 5 are push-button switch (KA1--KA4), and it equates with the quantity of electromagnet 8, comprises that also 6 is that switchette (K) and 7 is cable.(about 5 meters of length).

Channel selection control section 1 is connected with cable 7 between mains switch control section 2 and the hand-held remote control operation part 3.Press the signal that switchette 6 sends the control TV set power switch, press the signal that push-button switch 5 sends channel selection, these signals are sent to mains switch control section 2 by cable and channel selection control section 1 removes to carry out command adapted thereto.

Referring to Fig. 4, L1-L4 is an electromagnet coil among the figure, and B is a power transformer, and T1--T4 is a rectifier diode, C is a filtering capacitor, and J is a relay coil, and J1 is a relay contact switch, CZ is supply socket, and K is a switchette, and KA1-KA4 is a push-button switch.Behind closed switchette, the relay coil energising, the relay contact switch adhesive is connected the 220VAC of supply socket, makes the television set energized, can press the button switch then and make corresponding electromagnet coil power, to select corresponding channel.

Referring to Fig. 5, Fig. 5 is another embodiment schematic diagram, and 15 is fixed mount among the figure, and television set is another type (the channel preselection device is positioned at the bottom of television set front) among the figure.The figure mid band selects the internal structure of control section 1 not change, above-mentioned geometrical clamp 11 and 12 need not, and use fixed mount 15 instead, fixed mount 15 is made up of 2 L shaped supporting legs and 1 base plate, leg material is plastics or iron sheet, baseboard material is plank or plastic plate, 2 supporting legs are installed in the box left and right side of channel selection control section 1 respectively with screw, supporting leg is installed on the base plate with screw again, again television set is placed appropriate location on the base plate of fixed mount 15, make push rod 9 aim at the button of TV channel preselectors.The control signal that hand-held remote control operation part 3 is sent among the figure also can adopt the emission of radio wave or infrared waves to be sent to other parts, and signal removes to carry out command adapted thereto after amplifying.
