Composite computer input keyboard

Abstract

The invention discloses a composite computer input keyboard, which comprises a keyboard body, a shell and an air pressure device arranged on the inner side wall of the shell. The air pressure device comprises a limiting device, an air bag, a connecting pipe, an air pressure box, an extrusion plate, a threaded rod, a threaded pipe and an air spraying pipe. According to the device, a threaded pipe rotates to enable a threaded rod in threaded connection with the interior of the threaded pipe to move towards the outer side wall, and in the process that the threaded rod moves towards the outer side, an extrusion plate is pushed to enable gas in an air pressure box to enter an air bag, so that an air bag cushion is expanded under the action of the air bag, the hands can be supported conveniently, and hand ache caused by long-term work is prevented; and when the fixed plate is rotated reversely, the extrusion plate returns, air in the air pressure box is blown to the keyboard main body through the air spraying head, dust on the keyboard main body is blown away, the situation that the keyboard main body is contaminated by too much dust due to long-term use, and the normal service life of equipment is affected is avoided, and the cleanliness of the equipment is effectively improved.

Description

technical field [0001] The invention relates to the technical field of keyboards, in particular to a composite computer input keyboard.

Problems solved by technology

[0003] In the process of daily use of traditional keyboards, since the surface of the keyboard is exposed to the outside world for a long time, this will cause a lot of dust to adhere to the surface of the keyboard, and it is very difficult to clean. It often causes soreness because there is no place to rely on, and it is not convenient for users to work and use. Therefore, we propose a composite computer input keyboard to solve the above problems
