portable computer

Abstract

Provided is a portable computer, including a main body machine and a display. The rear end of the display is hinged with the rear end of the main body machine. First through holes are formed in the middles, close to the lower side, of the front, rear, left and right end faces of a shell of the body machine. A second through hole is formed in the middle of the shell bottom of the body machine. A vertical shaft is mounted in the second through hole through a bearing. Four transverse screw rods are arranged on the periphery of the upper end of the vertical shaft. The four screw rods are uniformlydistributed by taking the vertical shaft as the center. The screw rods are mounted at the inner bottom of the shell of the main body through bearing seats. Driven bevel gears are fixedly mounted at one ends of the screw rods. a driving bevel gear is fixedly installed at the upper end of the vertical shaft, driven bevel gears are meshed with the driving bevel gear in a matched mode, inner threadedpipes are installed at the other ends of the screws in a matched mode, the other ends of the inner threaded pipes are located at the inner ends of the corresponding first through holes, and side plates are arranged at the front, rear, left and right ends of a shell of the body machine. The computer is simple in structure, convenient to operate, high in durability and suitable for being used in severe environments.

[0002] The working environment of some technical staff of the long-term expedition team and engineering team is relatively harsh. They often encounter harsh working environments such as wind, sand, rain, snow, and dust, and their work is inseparable from computers. Traditional desktops cannot Portable, although existing notebook computers are portable, their performance and durability are not suitable for use in harsh environments. , high-definition cable interface, etc. enter the interior of the computer and cause damage to the computer. It is difficult to find a flat and clean plane to place the computer when working outside. Most of the cooling holes 23 of the traditional portable computer are located on the side and bottom. When the heat dissipation holes are easily blocked, the bottom of the traditional portable computer is also easily scratched by the uneven plane. When the staff reciprocates and goes to different areas, the display of the traditional portable computer only relies on the damping device on the hinge shaft to adjust the angle. Fixed, without a firm fixing device, the hinge of the display of the portable computer is easy to be damaged by the bumpy travel of the staff when they go back and forth to various areas. The traditional portable computer has no protection device on the periphery, and it is easy to be damaged by bumps
