Abstract

The utility model discloses a split keyboard for a computer, which belongs to the technical field of computers. The split keyboard consists of a keyboard substrate (5), press keys (6) and a host machine connecting wire (8), and is characterized in that the keyboard substrate (5) is divided into a left keyboard (1), a right keyboard (2) and a small keyboard (3), the left keyboard (1) and the right keyboard (2) are connected via a connecting conducting wire (7), and the right keyboard (2) and the small keyboard (3) are also connected via the connecting conducting wire (7). The split keyboard for a computer is simple in structure, and can not only lead operators to be comfortable during working but also reduce fatigue strength of the operators, thereby preventing occupational disease. In addition, the split keyboard simultaneously has functions of a mouse, and then can increase work efficiency of the operators.

Description

The split type keyboard of computing machine

Technical field

The utility model relates to a kind of improvement of computer keyboard, belongs to field of computer technology, the split type keyboard of specifically a kind of computing machine.

Background technology

At present, along with the raising of the penetration of computer use, computer keyboard has been a necessary tool in the work as the input equipment of computing machine.The layout of standard computer keyboard commonly used is a layout of having continued to use machinery typewriter now; computer keyboard generally comprises the function key zone; enter key zone and keypad area; wherein; the enter key zone is divided into left keyboard and left keyboard again according to input habit usually; when typewriting; because the keyboard of general computing machine and the form of mouse for separating; combination by computer keyboard and mouse is to computer input of Chinese characters and figure; because keyboard and mouse are used in combination; when carrying out the Chinese character input; position is very restricted; refer to; wrist; elbow; shoulder; the back of the body and neck through regular meeting owing to posture not to or the unbalance numerous disease that causes of right-hand man's workload, as one-sided arm pain; occupational illness such as singlehanded finger strain.In addition, because the keyboard profile is fixing, when carrying out the Chinese character input, when the user carries out computer operation according to standard sitting posture and standard fingering, palm need rotate a certain angle from outside to inside around upper arm, also to rotate a certain angle to the both hands outside along surface level, the easy like this wrist that causes is to the non-natural torsion of upper arm each several part and reversing, the user uses keyboard for a long time like this, cause the wrist numbness easily, the joint distortion, one-sided shoulder pain and illness such as crooked, form occupational illness, can't well regulate right-hand man's workload and comfort level, thereby reduce operating personnel's work efficiency.

Summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, it is comfortable that operating personnel are worked, and reduces operating personnel's fatigue strength, thereby prevent the generation of occupational illness, have mouse function simultaneously, and can improve the split type keyboard of computing machine of operating personnel's work efficiency.

In order to reach above purpose, the technical scheme that the utility model adopted is: the split type keyboard of this computing machine, constitute by keyboard matrix, button and main frame connecting line, it is characterized in that described keyboard matrix is divided into separate left keyboard, left keyboard and keypad, be connected with being connected lead between left keyboard and the left keyboard and between left keyboard and the keypad.

Be equipped with Petting Area on described left keyboard and the left keyboard.

The beneficial effects of the utility model are: according to the button of being accustomed to being convenient to operate by left hand left keyboard, operate the button of left keyboard and keypad by the right hand; By the Petting Area that cursor is moved is installed on left keyboard and the left keyboard, can replace mouse function, hand can be not be used between keyboard and the mouse to move around, thereby alleviated the fatigue of hand, reduced the incidence of computing machine occupational illness, and save this device of mouse, reduced cost, and, operating personnel are selected according to custom owing on left keyboard and the left keyboard Petting Area is installed all, easy to use; In addition, by being connected lead and can being adjusted to suitable spacing and angle between left keyboard and the left keyboard, between left keyboard and the keypad, make left keyboard, left keyboard and keypad be placed on the position of left hand and right hand sensation the most comfortable, can guarantee palm and upper arm natural torsion like this, it is comfortable to make the user operate, thereby prevent the generation of occupational illness, and can improve operating personnel's work efficiency.The utility model is simple in structure, uses comfortablely, can reduce operating personnel's fatigue strength, is fit to the computer operator and uses.
