Abstract

The invention discloses a press key fixing device used for installing a press key. The press key comprises a switch, the press key fixing device comprises a substrate provided with a through channel, and the through channel is used for containing the switch of the press key. The press key fixing device also comprises two first fixed walls which extend from two opposite sides of the through channel and are used for clamping the press key, a second fixed wall at least comprising one first backstop part, and an elastic sheet provided with at least one second backstop part, wherein, the second fixed wall extends out from one of the other two opposite walls of the through channel; the elastic sheet is arranged on one side of the through channel, which is opposite to the second fixed wall; and the first backstop part of the second fixed wall and the second backstop part of the elastic sheet are used for stopping the press key between the first backstop part of the second fixed wall and the second backstop part of the elastic sheet. When a press key is installed to the press key fixing device of the invention, the installation direction of the press key is vertical to the stress direction used by the press key so as to better solve the problem that the press key is easy to loose.

Description

technical field [0001] The invention relates to a button fixing device. Background technique [0002] Buttons are arranged on an electronic device, such as a computer case panel. Usually the button is mounted on a button fixing device of the panel, and the button is used to press the touch switch of the button installed on the button fixing device, so as to realize functions such as starting of the computer and ejecting of the CD-ROM. But, after using for a long time, the button will get loose from the button fixing device under the repeated pressing of the button, so that when the button is operated again, the purpose cannot be achieved. Trace it to its cause, this is because in common practice, the direction in which the key is installed in the key fixing device is the same as the direction of the force (that is, the pressing of the button) during use. Contents of the invention [0003] In view of the above, it is necessary to provide a key fixing device that can effec...
