Abstract
The utility model discloses a double number key computer keyboard, which comprises a computer standard keyboard and a small numeric keyboard. A USB slot is arranged on the left side of the computer standard keyboard, and the small numeric keyboard is mutually connected with the computer standard keyboard through a USB interface in a splitting way; a plurality of jacks/fixed detents are also arranged on the left side of the computer standard keyboard, a plurality of jacks/fixed detents are arranged at the corresponding positions of small numeric keys, and the fixed detents can be plugged in the jacks. Pointing at the technical deficiencies that the freeness and the busyness of the left and the right hands of the prior computer standard keyboard are uneven, and the number input efficiency is low, etc., discontinuous inputted numbers can be operated with the left hand, thus the utility model avoids the extensive movement of the right hand; for professionals which frequently use a plurality of application software such as an AutoCAD, and a Pro-ENGINEER, etc., the double hand operation is realized, thereby the further time is saved; by utilizing the USB interface, the hot swap is supported, the computer keyboard is installed when being required, and the computer keyboard is disassembled when being not required, and the computer keyboard can be reasonably utilized.
Description
Technical field
The utility model relates to a kind of computor-keyboard, a kind of specifically even numbers keyboard computor-keyboard.
Background technology
The computer QWERTY keyboard of using is generally all-in-one-piece single digital keyboard now, and small digital keyboard all is positioned at the right side of computor-keyboard.Along with the particularly a large amount of uses of software such as AutoCAD, Pro-ENGINEER of WINDOWS system, make click and the operation that the numeral input frequently replaces become very common, this has just increased the workload of the right hand greatly, because common people use the right-hand operated mouse more, and the small digital keyboard on the keyboard is positioned at the right side just, therefore the right hand should be operated mouse, operates the numerical key on right side again.As reach upper keyboard operand keyboard with left hand, also very inconvenient.As be positioned at row's numerical key of keyboard top with left-handed operation, because of this row's numerical key distribution range is not easy to one-handed performance greatly.Not only operate mouse but also operate under the situation of small digital keyboard at the right hand, with the frequent switching that causes the right hand between mouse and numerical key, left hand is then idle relatively, has therefore both reduced work efficiency, has influenced operating continuity and harmony again.Particularly for the professional of many application software such as frequent use AutoCAD, Pro-ENGINEER, this problem is just more outstanding.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, proposes the computor-keyboard of the even numbers word keyboard that a kind of right-hand man can use and conveniently dismantle simultaneously, easily.
The utility model discloses a kind of even numbers keyboard computor-keyboard, comprises the computer QWERTY keyboard, and small digital keyboard; The left side of described computer QWERTY keyboard offers the USB slot, and described small digital keyboard is connected in described computer QWERTY keyboard and links to each other by USB interface is split type; The left side of described computer QWERTY keyboard also is provided with a plurality of jack/Fixed latches, and described decimal keyboard relevant position is provided with a plurality of Fixed latches/jacks, and described Fixed latches can be inserted in the described jack.
More preferably, the button of described small digital keyboard is the arrangement of camber line shape.
Compared with prior art, the utility model adopts small digital keyboard hot swappable mode to be connected on the computer QWERTY keyboard, and its advantage is as follows:
1, for the discontinuity input digit, can carry out with left hand, avoided moving of the right hand on a large scale;
2, for the professional of many application software such as frequent use AutoCAD, Pro-ENGINEER,, thereby save more time with the operation of realization both hands;
3, utilize USB interface, support hot plug, install when needing, the time spent does not remove, thereby reaches the purpose of reasonable utilization.
Description of drawings
Fig. 1 is that the solid of the utility model one preferred embodiment splits structural representation.
Embodiment
Below by embodiment in detail, and its structure is described in detail in conjunction with the accompanying drawings:
Please refer to shown in Figure 1ly, be that the solid of the utility model one preferred embodiment splits structural representation.Even numbers keyboard computor-keyboard comprises computer QWERTY keyboard 10 and small digital keyboard 20.Wherein, the left side of described computer QWERTY keyboard 10 offers USB slot 11, and described small digital keyboard 30 links to each other with described computer QWERTY keyboard 10 by USB interface 21; The left side of described computer QWERTY keyboard 10 also is provided with a plurality of jacks 12, and described decimal keyboard 20 relevant positions are provided with a plurality of Fixed latches 22, and described Fixed latches 22 can be inserted in the described jack 12; The button 23 of described small digital keyboard 20 is camber line shape and arranges.
In this, the utility model provides a kind of even numbers keyboard computor-keyboard, has realized the purpose that the right-hand man can be simultaneously, used and conveniently dismantle easily.
