Computer rotating shaft positioning mechanism

Abstract

The invention provides a computer rotating shaft positioning mechanism, which is arranged between a computer mainboard and a liquid crystal screen board and comprises a first circle rolling part, a second circle rolling part, a first mandrel and a second mandrel, wherein the first circle rolling part is fixedly connected with the liquid crystal screen board, the second circle rolling part is fixedly connected with the computer mainboard, one end of the first mandrel extends into a circle rolling hole of the first circle rolling part and is tightly matched with the circle rolling hole of the first circle rolling part, one end of the second mandrel extends into a circle rolling hole of the second circle rolling part and is tightly matched with the circle rolling hole of the second circle rolling part, the other end of the first mandrel and the other end of the second mandrel are simultaneously, parallelly and fixedly arranged on a computer base, the first circle rolling part is a circle rolling tube which is formed by bending a rigid board along one end and is provided with a first axial opening groove, the first circle rolling part extends into a first end edge used for fixedly connecting the liquid crystal screen board along the other end, the second circle rolling part is a circle rolling tube which is formed by bending a rigid board along one end and is provided with a second opening groove, and the second circle rolling part extends into a second end edge used for connecting the computer mainboard along the other end. The computer rotating shaft positioning mechanism has the advantages that the liquid crystal screen board can singly rotate, in addition, the computer mainboard can also rotate relative to the opposite direction of the liquid crystal display board, and the use requirements of a traditional notebook computer and a tablet personnel computer are met.

Description

technical field [0001] The invention belongs to the improvement of a computer positioning shaft, in particular to a positioning shaft mechanism used for conversion between a notebook computer and a tablet computer. Background technique [0002] At present, the opening angle of notebooks in the computer industry is usually 135 degrees to 165 degrees, and the largest can only be opened to 180 degrees, which has met the usual requirements of users. However, if the notebook computer is used as a tablet computer at the same time, the LCD panel of the notebook computer will be rotated 180 degrees (to achieve that the LCD panel and the computer motherboard are on the same plane), and even the computer motherboard will be turned to a back-to-back state with the LCD panel, so that Notebook computer is used as tablet computer display screen, and traditional notebook computer is not competent, traces it to its cause: the rotation of existing notebook computer can only rotate in one dir...

Problems solved by technology

However, if the notebook computer is used as a tablet computer at the same time, the LCD panel of the notebook computer will be rotated 180 degrees (to achieve that the LCD panel and the computer motherboard are on the same plane), and even the computer motherboard will be turned to a back-to-back state with the LCD panel, so that Laptops are used as tablet display screens, and traditional notebooks are not competent. The reason is that the rotation of existing notebooks can only be rotated in one direction, and can only be rotated within less than 180 degrees (usually 165 degrees)
