Easy-opening and hard-closing rotation shaft

Abstract

The invention discloses an easy-opening and hard-closing rotation shaft, which comprises a rotating shaft and a fixation frame. The rotating shaft is provided with a backstop sheet, a bearing frame, several disk elastic sheets and a nut in order. One end of the rotating shaft is in fixed connection with the fixation frame, and the other end is fastened by the nut. A gear sheet is installed between the bearing frame and the disk elastic sheets on the rotating shaft. By adding a gear sheet and a clamping column, a screen can be prevented from dropping in advance during closing due to weight problem. Thus, the rotation shaft of the invention improves the convenience of laptop operation, and also considers the intrinsic quality and performance of a product.

Description

technical field [0001] The invention relates to a rotating shaft, in particular to a rotating shaft which is widely used to connect two components and enable relative rotation. Background technique [0002] Because the torque of the shaft needs to be able to support the screen at any angle, and have the same function after at least 20,000 life tests, the existing digital products such as notebooks must take the torque degradation into consideration when setting the torque, and will add An insurance factor makes the torque of the rotating shaft relatively large; therefore, the existing digital products such as notebooks use relatively large force when opening and closing, and the switch is basically the same, which will affect the user's hand feeling, and one hand needs to be opened when opening When the screen is lifted, the other hand must hold the base to keep it from tilting up, which is inconvenient to operate. Contents of the invention [0003] In order to overcome t...
