Abstract

Keyboard, including keyboard body, the USB line that is connected with host computer, the upper side of keyboard body are articulated with the groove set in cover plate and the plate cover lid keyboard body, several through holes are offered on the cover plate；The USB line is spacing by a through hole on cover plate；The top of the keyboard body is articulated with lamp socket, and the LED installed on lamp socket is connected with multiple-pole switch.The utility model proposes keyboard advantage it is as follows：USB line can be carried out spacing by the through hole of diverse location on cover plate, and adjustment USB line exposes aerial length, avoided producing with the foot of operator and contacted, so as to avoid the unexpected disconnection of keyboard and main frame；Lamp socket need to only be dug during night, LED is opened by multiple-pole switch, and adjusted to optimal brightness and keyboard can be used, avoiding, which influences other people, rests.

Description

Keyboard

Technical field

It the utility model is related to a kind of computer entry device, and in particular to a kind of keyboard.

Background technology

Keyboard is a kind of equipment for computer input, is connected usually through USB line with host computer and realizes input function. In order to ensure the connection of keyboard and host computer, USB line is all longer at present, and except two ends, remaining is largely all exposed to In air.When operator uses computer, its foot often steps down on USB line or wound by USB line, when operator rises suddenly During body, big city causes USB line stress suddenly, is easier to disconnect the connection with main frame and the service life of shortening keyboard.Pass simultaneously System keyboard does not possess illumination functions, and when night uses computer, if do not turned on light, keyboard does not see Chu；If turned on light, him is influenceed again People rests.

The content of the invention

The purpose of this utility model is to provide a kind of keyboard, and technical problem to be solved is can Reasonable adjustment USB line exposes aerial length, and has illumination functions, thus more suitable for practicality.

The purpose of this utility model and to solve its technical problem realized using following technical scheme.It is new according to this practicality The keyboard that type proposes, including keyboard body 1, the USB line 2 that is connected with host computer, the upper side of keyboard body 1 are articulated with cover plate 12 and the cover lid keyboard body 1 of the cover plate 12 in groove 11 for setting, offer several through holes 121 on the cover plate 12；The USB Line 2 is spacing by a through hole 121 on cover plate 12；

The top of the keyboard body 1 is articulated with lamp socket 13, and the LED 14 installed on lamp socket 13 is connected with multiple-pole switch 15.

The purpose of this utility model and solve its technical problem and also realized using following technical measures.

Foregoing keyboard, each through hole 121 are semicircle.

Foregoing keyboard, the LED 14 are provided with 3.

By above-mentioned technical proposal, the utility model proposes keyboard there is advantages below：

(1) USB line can be carried out spacing by the through hole of diverse location on cover plate, and adjustment USB line exposes aerial length Degree, avoid with the foot of operator produce contact, so as to avoid the unexpected disconnection of keyboard and main frame；

(2) illumination functions.Lamp socket need to only be dug during night, LED is opened by multiple-pole switch, and adjusted to optimal bright Keyboard can be used in degree, and avoiding, which influences other people, rests.

Described above is only the general introduction of technical solutions of the utility model, in order to better understand technology of the present utility model Means, and being practiced according to the content of specification, and to allow above and other purpose of the present utility model, feature and excellent Point can become apparent, and below especially exemplified by preferred embodiment, and coordinate accompanying drawing, describe in detail as follows.

Embodiment

Further to illustrate that the utility model is to reach the technological means and effect that predetermined goal of the invention taken, below With reference to accompanying drawing and preferred embodiment, to according to the utility model proposes keyboard its embodiment, structure, feature and its work( Effect, describe in detail as after.

Refer to Fig. 1 and Fig. 2A, Fig. 2 B, the utility model proposes keyboard, including keyboard body 1, with host computer phase USB line 2 even, the upper side of keyboard body 1 are articulated with the groove set in cover plate 12 and the cover lid keyboard body 1 of cover plate 12 11, several semicircular through holes 121 are offered on the cover plate 12；The USB line 2 passes through one of through hole on cover plate 12 121 is spacing.

Referring to Fig. 3, the top of the keyboard body 1 is articulated with lamp socket 13,3 LEDs 14,3 are equiped with lamp socket 13 Individual LED 14 is all connected with multiple-pole switch 15.Specifically, multiple-pole switch 15, which can not only control, opens or closes 3 LEDs 14, And the brightness of LED 14 can also be adjusted, meet the use demand of the operator of different age group.Multiple-pole switch 15 and key simultaneously The internal circuit of disk body 1 is in parallel.

The utility model proposes keyboard operation principle it is as follows：

Fig. 2A, Fig. 2 B are referred to, USB line 2 is drawn by the left side (or right side) inside groove 11, passes through its on cover plate 12 In a through hole 121 it is spacing after be connected with main frame.If operator thinks that the aerial length of USB line exposure is long, Cover plate 12 need to only be dug, USB line is spacing by another through hole 121 of one right side of through hole 121 (or left side), then Cover plate 12 is turned down into fastening can shorten the aerial length of USB line exposure.If operator thinks that USB line is exposed to air In length it is too short when, cover plate 12 need to only be dug, USB line is passed through into the another of the left side of one through hole 121 (or right side) Individual through hole 121 is spacing, then cover plate 12 is turned down into fastening can extend USB line and expose aerial length.

If being used at night, lamp socket 13 is dug, then LED 14 is opened by multiple-pole switch 15, and is adjusted to optimal Brightness, keyboard can be used and avoid influenceing other people rests.Daytime by multiple-pole switch 15 in use, only need to close LED 14, then lamp socket 13 is turned down, avoids damaging LED 14.

It is described above, only it is preferred embodiment of the present utility model, not the utility model is done any formal Limitation, any person skilled in the art, do not departing from the range of technical solutions of the utility model, it is new according to this practicality The technical spirit of type still falls within the utility model to any simple modification, equivalent change and modification made for any of the above embodiments In the range of technical scheme.
