Abstract
The utility model discloses an external keyboard with an adjustable inclined angle. The external keyboard comprises a keyboard shell, buttons and more than one regulating assembly. As a thread section is connected with a boss through threads, after a screw is rotated, the screw moves relative to the boss, and the screw drives a sliding block in a moving process. A supporting arm supports the whole keyboard through a supporting shaft and the sliding block, after the sliding block is moved, the angle of the supporting arm is changed, and the inclined angle of the keyboard is further changed. As the sliding block can move within a relatively large range, the inclined angle of the keyboard can be changed within a relatively large range through the supporting arm. By means of the self-locking effect of the threads, the position of the sliding block can be regulated by rotating the screw; meanwhile, pressure of the supporting arm can not move the sliding block.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The adjustable external connection keyboard in of the present utility model this inclination angle as shown in Fig. 1 to 5, comprises keyboard case 1, button 2 and two adjusting parts 3.
Described keyboard case 1 is tabular rectangular structure, is provided with for supporting the basic circuit of computer input in it.Keyboard case 1 has the first side 11 and the second side 12, and this first side 11 and the second side 12 are the main surface of keyboard, and for user, the first side 11 is positive, the second 12Wei back, side.
Described button 2 is arranged on described the first side 11, and the number of this button 2 meets basic input demand, can be common 93# button, and button 2 does not belong to the technical problem to be solved in the present invention, at this, does not describe in detail.
Described the second side 12 is provided with two symmetrical installation positions, and each installation position is equipped with a chute 121, a back shaft 122 and a boss 123.The length of chute 121 meets the demand of slide block 31 slips and the demand that sway brace 33 rotates simultaneously.Described back shaft 122 and boss 123 lay respectively at the two ends of described chute 121, and the axis of described back shaft 122 is vertical with the axis of described screw rod 32.Described boss 123 has a threaded hole 1231, and the thread parameter of going back threaded hole is identical with the thread parameter of thread segment 321.
Described adjusting part 3 is two, is symmetrically distributed on described the second side 12, is distributed on installation position.Described adjusting part 3 comprises slide block 31, screw rod 32 and sway brace 33.Described slide block 31 is slidably disposed in described chute 121, and slide block 31 can correspondingly be provided with screens portion and screens groove with chute 121, so that slide block can be stably in the interior slip of chute 121.
Described screw rod 32 is comprised of thread segment 321 and canned paragraph 322, and described thread segment 321 is threaded connection with described threaded hole 1231.Preferably, the helical pitch of described thread segment 321 represents with H, represents H≤R/4 with the nominal diameter of this thread segment 321 with R; Described screw rod 32 is fabricated from iron, and described boss 123 is made of plastics.This preferred version can increase screw thread friction force on the one hand, can reduce the angle of rifling on the other hand, to meet the needs of screw thread self-locking.Described canned paragraph 322 is rotating to be connected on described slide block 31, the utility model has no particular limits its concrete fixed form, with reference to Fig. 4, has a large footpath section on this canned paragraph 322, in slide block 31, have a reaming section, this large footpath section is positioned at described reaming section.By this structure, screw rod 32 can rotate and can not move with respect to slide block 31 with respect to slide block 31 simultaneously.
Described sway brace 33 is rotating to be connected on described back shaft 122, and the length of chute 121 has been reserved the holding portion of sway brace 33, and the distance away from slide block 31 one end of back shaft 122 and chute 121 is greater than the length of sway brace 33.The height of slide block 31 is too small, and sway brace 33 can be by main pressure transfer to slide block 31; Slide block 31 is highly excessive, limited to the regulating power of sway brace 33.Preferably, the height of described slide block 31 is the twice of described back shaft 122 height, and the distance of one end away from chute 121 of slide block 31 and chute 121 bottoms equals the twice of back shaft 122 and chute 121 bottom ultimate ranges.
