Abstract

The utility model discloses a mechanical password switch of a television, which comprises a mechanical lock body fixed on the casing body of the television and is connected with the outer side of the switch of the television; the mechanical lock body comprises an encoder and a baffle, wherein the encoder is composed of three groups of rotating digital code wheels; the switch is arranged in the baffle. The password switch has the advantages that password control can be effectively realized, the operation is convenient, and the password switch is suitable for all televisions.

Description

Mechanical television secret code switch

Technical field

The utility model relates to a kind of cipher switch, especially is placed in the mechanical code switch on the television set.

Background technology

Television set is a kind of household electrical appliance of having popularized.Television set can bring various information and general entertainment programme to people, but also can bring negative effect to child.Studies show that, a little less than child's control, watch TV can cause the infringement of its body and mind for a long time.Therefore, the adult need control the unlatching of television set many time, to reach the purpose that the control child watches TV.

Chinese patent CN2316778 number disclosed " a kind of television set cipher switch " patent (application number: 97245594.9), output one end of rectifier is communicated with one group of gate circuit with one group of output pin through locking switch, the output of each gate circuit is controlled by locking switch separately, the output of the last gate circuit is controlled connect with the control coil of relay gate circuit in the output loop that is serially connected with rectifier simultaneously of another its output, the contact of relay and connecting respectively with between light-emitting diode and power supply and the socket, the output of gate circuit can move the joint that is connected with it and connect with one respectively.The weak point of this patent is: structure is too complicated, damage easily, and operation inconvenience.

Summary of the invention

The purpose of this utility model is exactly that a kind of mechanical television simple in structure secret code switch will be provided, and makes the adult can control the unlatching of television set easily.

In order to achieve the above object, the mechanical television secret code switch that the utility model provides comprises a mechanical lock body, is fixed on the tv shell, is connected the television set switch outside; The machinery lock body comprises encoder, catch, and wherein encoder rotates digital password wheels by three groups and forms; Switch is placed within the catch.The rotation digital encoder structure of machinery lock body is a prior art, is widely used in bag, case field, repeats no more here.When the utility model uses, have only three groups of rotation numerical ciphers to after accurate, can push catch aside, the switch open within the control catch.

The mechanical television secret code switch that the utility model provides has positive effect: comprises a mechanical lock body, is fixed on the tv shell, be connected the television set switch outside, and simple in structure, can effectively realize cipher control, easy to use.

Description of drawings

The utility model will be further described in conjunction with the accompanying drawings, please referring to accompanying drawing:

Accompanying drawing 1 expression schematic diagram of the present utility model.

Structure shown in the accompanying drawing 1 comprises: casing 1, mechanical lock body 2, encoder 3, catch 4, switch 5.The mechanical television secret code switch that embodiment the utility model provides comprises a mechanical lock body 2, is fixed on television cabin 1 body, is connected television set switch 5 outsides; Machinery lock body 2 comprises encoder 3, catch 4, and wherein encoder 3 rotates digital password wheels by three groups and forms; Switch 5 is placed within the catch 4.Rotation digital encoder 3 structures of machinery lock body 2 are prior art, are widely used in bag, case field, repeat no more here.When the utility model uses, have only three groups of rotation numerical ciphers to after accurate, can push catch 4 aside, the switch 5 within the control catch 4 is opened.

The utility model protection range relates to all changes form recited above.
