Abstract

The utility model relates to an anti-destroy keyboard, which comprises a casing, a guide positioning plate, and an electronic switch. The structure thereof is characterized in that keys arranged on the casing are provided with key caps whose the diameters are larger than the key caps of key holes. The key body positioned on the inner side of the casing is provided with a clamping device, and the keys can not be pressed and pulled out under the strong force. The anti-damage capability of the utility model is improved, and the utility model is suitable for outdoor use.

Description

The anti-keypad that destroys

The utility model relates to the keyboard technique field.

Be provided in the electronic switch keypad on the various electric equipments at present, its overall structure all is to be made of the some electronic switches that are installed on plurality of keys on the guide positioning plate and button below.According to the structure difference of electronic switch, substantially can be divided into three types of light touch switch type, conducting resinl formula and full rubber types again.Above-mentioned three types electronic key dish is used for the various instrument and equipments of office work, its good performance is justifiable, but all there is a common weakness in they, be exactly that survivability is poor, be unable to undergo to knock, thereby be not suitable for being used on the various device of outside work, as electronic password lock, the keypad of stair calling set, electronic door bell etc.

The purpose of this utility model is exactly the electronic switch keypad that will provide a kind of survivability strong, thereby guarantees the safety of the electric apparatus control apparatus of various outside works.

For achieving the above object, the utility model is by the following technical solutions: have several keyholes on a metal shell, button is housed in the keyhole, the shell inboard by bolt be equipped with have on it with shell on the guide positioning plate of same quantity keyhole, the guide positioning plate inboard all is equipped with electronic switch corresponding to each keyhole place, its design feature is that the end that button exposes shell has the keycap of diameter greater than the keyhole diameter, has the OK a karaoke club device that prevents that button from extracting on the key body of button inside the shell.

Because button of the present utility model has keycap and the OK a karaoke club device of diameter greater than the keyhole diameter, when depressing button, electronic switch is connected, and continues to press down or clash into button if use violence again, keycap is propped up and can not move down by shell, thereby can protect electronic switch not to be damaged; When drawing button on exerting oneself, the OK a karaoke club device props up inner surface of outer cover, and button can not be drawn out, thereby the utility model has very strong survivability, the electric apparatus control apparatus use of suitable outdoor mounted.

Below in conjunction with drawings and Examples, the utility model is described in further detail.

Fig. 1 is an overall structure schematic diagram of the present utility model;
