Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

The embodiment provides an external ultra-thin keyboard of flat board, and the device is through adjusting pole 9, connecting rod 10, telescopic link 11 and connecting block 15, and cooperation sucking disc 16 can be adjusted the angle of panel computer, avoids when using the keyboard, is located a horizontal plane for a long time, leads to user's arm to be in under certain fixed state always, long-time typing back, the easy phenomenon that appears the aching pain of arm.

Referring to fig. 1 to 5, the tablet computer comprises a keyboard body 1, wherein a connecting plate 2 is hinged to the outer surface of the keyboard body 1 through a pin shaft, the keyboard body 1 is the most common and most main input device, and English letters, chinese characters, numbers, punctuations and the like can be input into the tablet computer through the keyboard body 1, so that commands, input data and the like are sent to the tablet computer.

The inner wall of connecting plate 2 rotates and is connected with rotary rod 3, and the outer fixed surface of rotary rod 3 is connected with gear 4, and rotary rod 3 rotates at the inner wall of connecting plate 2, and manual rotation rotary rod 3, rotary rod 3 drive gear 4 and rotate.

The upper surface sliding connection of connecting plate 2 has two symmetrical racks 5, and two racks 5 all mesh with gear 4 mutually, drive two racks 5 through rotating gear 4 and remove, and two racks 5 move towards the direction that is close to each other or keeps away from each other.

The equal fixedly connected with fixed plate 6 of upper surface of two racks 5, the last fixed surface of connecting plate 2 is connected with puts thing platform 7, places the panel computer on putting thing platform 7, moves towards the direction that is close to each other through moving two fixed plates 6 of rack 5 drive to the panel computer of placing on putting thing platform 7 is fixed.

Two symmetrical grooves 8 of accomodating have been seted up at the back of connecting plate 2, and two inner walls of accomodating groove 8 all articulate through the round pin axle have an adjusting rod 9, and the length of adjusting rod 9 is less than the length of accomodating groove 8, can accomodate adjusting rod 9 and put the inside of accomodating groove 8.

The bottom of two regulation poles 9 all has connecting rod 10 through the round pin axle is articulated, and the equal sliding connection of inner wall of two connecting rods 10 has telescopic link 11, through sliding telescopic link 11 in connecting rod 10 the inside to the drive is adjusted pole 9 and is removed, adjusts the angle between panel computer and the keyboard body 1 through adjusting pole 9.

The first screw hole 12 that the equidistance was arranged is all seted up to the surface of two telescopic links 11, and second screw hole 13 is all seted up to the surface of two connecting rods 10, through sliding telescopic link 11, places first screw hole 12 in under second screw hole 13.

The surface of threaded rod 14 and the inner wall threaded connection of first screw hole 12, the equal threaded connection of inner wall of two second screw holes 13 has threaded rod 14, rotates threaded rod 14, is in the same place connecting rod 10 and telescopic link 11 are fixed through threaded rod 14, avoids when using the keyboard, because telescopic link 11 does not have fixedly to the telescopic link 11 appears at the gliding phenomenon in connecting rod 10 the inside, causes unstable phenomenon.
