Description

Plug latch

The utility model relates to a kind of attaching plug that can pin electrical appliance, particularly needs the special messenger to control the device of attaching plug of the electrical appliance of use.

Some electrical appliance as television set, video recorder etc., is needing the special messenger to control use in some cases.Such as preventing that child from seeing TV, video recording too much.Because at present not unified, effective form, some people packs television set, video recorder in one cupboard into.Control the use of electrical appliance with the method for pinning cupboard.Also there is the people that the room that is placed with television set, video recorder is pinned the use of controlling electrical appliance.

The purpose of this utility model provides a kind of simple in structure, easy to use, device that cost is low.Use this device can reach the special messenger effectively and control the purpose of using electrical appliance.

The purpose of this utility model is achieved in that mechanical lock and socket is equipped with in inside and closable housing is made one.Closing by mechanical lock control of housing that is to say, key is inserted when rotating in the mechanical lock, can open or pin housing.Just as pinning with lock or opening cupboard, not having key is to open or to pin housing.Open housing, can be in the socket in the attaching plug of the electrical appliance insertion housing.After pinning housing, not having key is to take out the attaching plug of electrical appliance in housing.In addition, key is inserted when rotating in the mechanical lock, not only can open or pin housing, but also can be switched on or switched off the electric current on the housing interpolation block.Lead-out wire on the housing interpolation block links to each other with external power source.And provide power supply for electrical appliance by it.When using electrical appliance, the socket in the attaching plug insertion housing of electrical appliance is got final product.When not using, housing is pinned, and cut off the electricity supply simultaneously with key.Because other people can't be for electrical appliance provides power supply, and can not use electrical appliance, so just can reach the purpose that the special messenger controls the use electrical appliance.

Such scheme is to reach the purpose that the special messenger uses electrical appliance by the power supply of controlling electrical appliance, needs change electrical appliance itself.Use this device, can not bring any influence electrical appliance.

The concrete structure of utility model is provided by following embodiment and accompanying drawing.

Fig. 1 is the sectional drawing according to the plug latch that the utility model proposes.

Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

When key inserts mechanical lock (1) rotation, can drive cam (2) and rotate together.When the convex portion of cam (2) turns to the left side, because the effect of spring (4) moves upward the compound body (3) of latch and switch rod.Latch moves upward, and makes latch leave the recess of closure plate (9).At this moment, closure plate (9) can be released to the left and right sides along the groove of housing (8).And the switch rod moves upward, and the conductor of its bottom (6) is connected socket (7) and external power supply contact (5).At this moment, if lead-out wire (10) is linked to each other with external power source, socket (7) just can provide power supply for electrical appliance.If the use electrical appliance, insert the attaching plug of electrical appliance in the socket (7) and the closure plate of closing (9) just passable.If do not use electrical appliance, and prevent that other people from using, once more key is inserted mechanical lock (1) and rotate, drive cam (2), make convex portion turn to the below, its compound body (3) that promotes latch and switch rod is moved downward.Latch moves downward, and enters the recess of closure plate (9).Closure plate (9) can't be moved, thereby the attaching plug of electrical appliance also can't take out from housing (8).The switch rod moves downward, and has disconnected being connected of external power supply contact (5) and socket (7), has promptly cut off the power supply of electrical appliance, and electrical appliance can't be worked, and has reached the special messenger and has controlled the purpose of using electrical appliance.

Claims (1)

1, plug latch, in closable housing, mechanical lock and socket separating device is characterized in that: the cam on the mechanical lock links to each other with the compound body of latch with the switch rod, thereby make mechanical lock and socket switch, housing close synchronous operation.
