Abstract
The invention discloses a keyboard with a telescopic hand support. The keyboard comprises an upper shell (1) and a lower shell (2) which are matched mutually, wherein an accommodating cavity (3) and a passage (4) are formed in the lower shell (2); the passage (4) is communicated to the accommodating cavity (3) from the front end of the lower shell (2); a scroll (6) is arranged in the accommodating cavity (3); both ends of the scroll (6) are connected with both ends of the accommodating cavity (3) by coil springs (7); the scroll (6) is wound with fiber cloth (8); one end of the fiber cloth (8) passes through the passage (4) and is fixed at the upper edge of the front end of the lower shell (2); chutes (9) are formed at both ends of the lower shell (2); push rod mechanisms are arranged in the chutes (9) and are used for pushing out the fiber cloth (8) to form the keyboard hand support; when the keyboard hand support does not need to be used, the push rod mechanisms are pushed backwards, the scroll rotates under the drive of the coil springs to wind the fiber cloth into the lower shell, and use of the keyboard is not influenced.
Description
Technical field
The present invention relates to a kind of keyboard with scalable hand rest, belong to computer fittings technical field.
Background technology
The hand rest of keyboard be keyboard bottom for holding in the palm the parts of arm, not all keyboard all with.Increase at keyboard
If hand rest, wrist can be held up to facilitate use keyboard, its shortcoming be by the keyboard that accounts for before part table top, and work as
Table top is narrow, keyboard when the forward position of workbench, cause the existing keyboard with hand rest to use, hands
Arm still lacks suitable supporting.
Therefore it provides the keyboard of a kind of band hand rest, this hand rest is telescopically installed on inside keyboard lower house, when
Table top is narrow or keyboard is when the forward position of workbench, can be taken in inside keyboard lower house by hand rest, not affect
The use of keyboard, with the problem overcoming existing keyboard hand support to take the part table top before keyboard.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of keyboard with scalable hand rest, when table top is narrow
Or keyboard is when the forward position of workbench, hand rest can be taken in inside keyboard lower house, not affect making of keyboard
With, with the problem overcoming existing keyboard hand support to take the part table top before keyboard..
It is an object of the invention to be achieved through the following technical solutions:
A kind of keyboard with scalable hand rest, including the upper shell cooperated and lower house, the button of keyboard
Being arranged on upper shell, be provided with containing cavity and passage on described lower house, containing cavity is positioned in the middle of lower house
Position, passage is communicated to containing cavity by the front end of lower house, is provided with rotating shaft in containing cavity, and spool two ends lead to
Crossing wind spring to be connected with the two ends of containing cavity, spool is wound with fiber cloth, fiber cloth one end is through passage and fixes
At upper edge, lower house front end, lower house two ends are provided with chute, in chute, are provided with transfer bar mechanism use
Keyboard hand support is formed in fiber cloth being released.
Preferably, described transfer bar mechanism includes push rod, slide block and cross bar, and cross bar connects left and right two push rods
Front end formed " U " type structure, cross bar is positioned at the inner side of fiber cloth, and described slide block is arranged on the rear end of push rod
And slide in chute.The simple in construction of transfer bar mechanism, easy to use.
Preferably, described cross bar is provided with multiple roller.Pulley is set, by between cross bar and fiber cloth
Friction becomes sliding friction, has both been easy to part fiber cloth and has released from lower house is internal, reduce again fiber cloth and cross bar it
Between abrasion.
Preferably, the front end at lower house is provided with groove.By arranging groove, when need not use fiber cloth
The when of the keyboard hand support formed, may be used for receiving described roller and cross bar, contribute to reducing whole keyboard
Width.
Compared with prior art, the invention have the benefit that the present invention to pass through inside lower house and fiber is set
Cloth, and by transfer bar mechanism, fiber cloth is released formation and can form keyboard hand support, when in use, fiber
Cloth soft comfortable, has good breathability simultaneously.It addition, when table top is narrow or keyboard is near workbench
During forward position, can promote transfer bar mechanism backward, the drive spool at wind spring rotates and is involved in inside lower house by fiber cloth,
Do not affect the use of keyboard.

Detailed description of the invention
Below in conjunction with the accompanying drawings and invention is described further by specific embodiment:
A kind of keyboard with scalable hand rest, including the upper shell 1 cooperated and lower house 2, keyboard
Button 5 is arranged on upper shell 1, is provided with containing cavity 3 and passage 4, containing cavity on described lower house 2
3 are positioned at lower house 2 centre position, and passage 4 is communicated to containing cavity 3 by the front end of lower house 2, at containing cavity
Being provided with rotating shaft 6 in 3, spool 6 two ends are connected with the two ends of containing cavity 3 by wind spring 7, and spool 6 twines
Be wound with fiber cloth 8, fiber cloth 8 one end through passage 4 be fixed at upper edge, lower house 2 front end, under
Housing 2 two ends are provided with chute 9, are provided with transfer bar mechanism for fiber cloth 8 is released formation in chute 9
Keyboard hand support.
Described transfer bar mechanism includes push rod 10, slide block 11 and cross bar 12, and cross bar 12 connects left and right two
