Abstract

The utility model discloses a CAD special keyboard, comprising a common keyboard (1) and an auxiliary keyboard (2). The auxiliary keyboard (2) is additionally arranged at the left side of the common keyboard (1) and includes keys of R, O, S, C, H, A, P, L, M, T, E, X and a space key, and the keys of R, O, S, C, H, A, P, L, M, T, E, X and the space key have the same electric signal source as the relative keys of R, O, S, C, H, A, P, L, M, T, E, X and a space key of the common keyboard (1). The keys of R, O, S, C, H, A, P, L, M, T, E, X and the space key which are used commonly in CAD drawing are centralized in an area, thereby improving the input speed and drawing efficiency.

Description

The CAD keyboard special

Technical field

The utility model relates to a kind of computor-keyboard, particularly relates to a kind of CAD keyboard special.

Background technology

The permutation and combination of existing computor-keyboard considers that all the operating habit of people's left hand and right hand is provided with, this keyboard is adapted at using under the general situation, but the use that button R, O, S, C, H, A, P, L, M, T, E, X and space bar can be frequent when people utilize computer to carry out the CAD drawing, these buttons are not the same area that concentrates on keyboard, and people are when carrying out the CAD drawing, it generally all is right hand mouse beacon, the left-handed operation keyboard, so it is very inconvenient that one hand carries out keyboard operation, influenced drawing speed.

The utility model content

At above-mentioned the deficiencies in the prior art part, the utility model provides a kind of CAD keyboard special, can address the above problem fully.

The technical solution adopted in the utility model is: a kind of CAD keyboard special, comprise keyboard commonly used, it is characterized in that: additional keyboard is set up on the left side at keyboard commonly used, described additional keyboard is made of button R, O, S, C, H, A, P, L, M, T, E, X and space bar, the electric signal of button R, O, S, C, H, A, P, L, M, T, E, X and space bar source with use keyboard always on button R, O, S, C, H, A, P, L, M, T, E, X and space bar have identical source accordingly.

It is five layers that above-mentioned a kind of CAD keyboard special, described additional keyboard are divided into, and from top to bottom button R, O, S are ground floor, and button C, H, A are the second layer, and button P, L, M are the 3rd layer, and T, E, X are the 4th layer, and space bar is separately as layer 5.

Above-mentioned a kind of CAD keyboard special, the size of button R, O, S, C, H, A, P, L, M, T, E and X on the described additional keyboard, shape, structure are identical with the conventional key of existing computor-keyboard, the space key length is 3 times of alphabet key, and its shape is identical with conventional space bar with structure.

Above-mentioned a kind of CAD keyboard special, the electric signal source of button R, O, S, C, H, A, P, L, M, T, E, X and space bar on the described additional keyboard is in parallel with button R, O, S, C, H, A, P, L, M, T, E, X and space bar on using keyboard always.

Advantage of the present utility model is: button R, O, S, C, H, A, P, L, M, T, E, X and space bar commonly used concentrated and is arranged on a zone when CAD was charted, and improved input speed and drawing efficiency.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

As shown in Figure 1, a kind of CAD keyboard special, comprise keyboard 1 commonly used, set up additional keyboard 2 on the left side of keyboard 1 commonly used, described additional keyboard 2 is made of button R, O, S, C, H, A, P, L, M, T, E, X and space bar, the electric signal of button R, O, S, C, H, A, P, L, M, T, E, X and space bar source with use keyboard 1 always on button R, O, S, C, H, A, P, L, M, T, E, X and space bar have identical source accordingly.

Above-mentioned a kind of CAD keyboard special, it is five layers that described additional keyboard 2 is divided into, and from top to bottom button R, O, S are ground floor, and button C, H, A are the second layer, and button P, L, M are the 3rd layer, and T, E, X are the 4th layer, and space bar is separately as layer 5.

Above-mentioned a kind of CAD keyboard special, the size of button R, O, S, C, H, A, P, L, M, T, E and X on the described additional keyboard 2, shape, structure are identical with the conventional key of existing computor-keyboard, the space key length is 3 times of alphabet key, and its shape is identical with conventional space bar with structure.

Above-mentioned a kind of CAD keyboard special, the electric signal source of button R, O, S, C, H, A, P, L, M, T, E, X and space bar on the described additional keyboard 2 is in parallel with button R, O, S, C, H, A, P, L, M, T, E, X and space bar on using keyboard 1 always.

This CAD keyboard special is with CAD drawing shortcut key combinations commonly used, measured zone and girth AA, paint circular arc A, draw circle C, skew O, mobile M, straight line L, multistage line PL, chamfer CHA, rotate RO, duplicate CO, characteristic matching MA, mirror image MI, fill H, multirow literal T, extend EX, be revised as object characteristic CH, proportional zoom SC and concentrate on a zone, make things convenient for one-handed performance, improved drawing efficiency.
