Detailed Description
The utility model provides a possess the threading and dodge the notebook computer pivot of structure. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.
As shown in fig. 1-4, a notebook computer rotating shaft 1 with a threading avoiding structure includes a fixed end 2 and a movable assembly shaft 3, the movable assembly shaft 3 is sleeved with a movable turning page 4, the movable turning page 4 is fixed on a body 5 of the notebook computer, and the fixed end 2 is fixedly connected with a liquid crystal display main body of the notebook computer.
The movable assembly shaft 3 is a hollow shaft, the movable assembly shaft 3 is provided with a threading hole 31 corresponding to the movable turning page 4, the outer side of the middle of the movable assembly shaft 3 is provided with a gear tooth 32, one side of the gear tooth 32, which is close to the fixed end 2, is provided with a stop ring 33, and the outer diameter of the stop ring 33 is not smaller than the diameter of the addendum circle of the gear tooth 32. The movable turning page 4 is provided with an assembly gear shaft 41, the outer side of the assembly gear shaft 41 is sleeved with a matching gear 42, and the matching gear 42 is meshed with the gear teeth 32. The outer side of the movable assembling shaft 3 is provided with an assembling ring 34, the assembling ring 34 is arranged between the stopping ring 33 and the fixed end 2, the outer diameter of the assembling ring 34 is not smaller than the diameter of the addendum circle of the gear teeth 32, and a concave ring is formed between the stopping ring 33 and the assembling ring 34.
During assembly, the cable 7 is led out from the body 5 of the notebook computer, enters the movable turnover page 4, is extended to the fixed end 2 along the movable assembly shaft 3 through the threading hole 31, and finally extends out from the movable assembly shaft 3 and is connected with the liquid crystal screen main body of the notebook computer.
Therefore, the cables 7 are integrally arranged in a U shape, when the liquid crystal display main body of the notebook computer and the body 5 of the notebook computer are opened to form 180 degrees, the cables 7 are arranged in a Z shape, and the cables 7 in the movable assembly shaft 3 are twisted.
