Detailed Description

In order to make the understanding of the other features and advantages of the present invention and the efficacy achieved thereby more apparent, the present invention will now be described in detail with reference to the accompanying drawings, wherein:

referring to fig. 1, fig. 2 and fig. 3, the present invention provides a screen adjusting device, which includes: a combination base 1, a base 2, an upper shaft 3, a lower shaft 4 and two supporting members 5.

The combination base 1 is provided with a screen 6, the combination base 1 can be fixed on the back of the screen 6, and the screen 6 can be an external screen, a notebook computer, a palm computer, a screen of a smart phone or screens of other electronic devices, but is not limited thereto. The base 2 is separated from the combining seat 1 by a distance.

The upper rotating shaft 3 is pivoted to the combining seat 1, and the upper rotating shaft 3 is used for rotating the combining seat 1, so that the screen 6 can adjust the viewing angle along with the rotation of the combining seat 1.

The lower rotating shaft 4 is pivoted to the base 2, and the lower rotating shaft 4 is further connected with the two supporting members 5, so that the two supporting members 5 can rotate relative to the base 2.

As shown in fig. 3 and 4, the two supporting members 5 are disposed in parallel and spaced apart, and each supporting member 5 includes two rod members 51, and an upper fixing ring 52 and a lower fixing ring 53 fixed to two ends of the rod member 51. The rod 51 has a pin hole 511 at each end and is connected to the upper fixing ring 52 or the lower fixing ring 53. The peripheries of the upper fixing ring 52 and the lower fixing ring 53 are fixed with the pin holes 511 of the two rod members 51 by two bolts 521 or 531, so that the two ends of the rod member 51 are respectively combined with the upper fixing ring 52 and the lower fixing ring 53. The upper rotating shaft 3 is disposed between the two upper fixing rings 52, and the lower rotating shaft 4 is disposed between the two lower fixing rings 53, so that the two rods 51 are combined with the upper rotating shaft 3 and the lower rotating shaft 4 to form a parallel four-bar linkage mechanism.

As shown in fig. 4 and 5, when the two supporting members 5 rotate around the lower shaft 4, the turning radius of the two supporting members 5 is used as the turning range, so that the two rods 51 generate a relative motion of pushing and pulling to make the two upper fixing rings 52 synchronously turn, please match fig. 6 and 7, the upper shaft 3 rotates along with the two upper fixing rings 52 to link the combining base 1 to turn, so as to make the screen 6 on the combining base 1 rotate. Therefore, the two supporting pieces 5 can drive the upper rotating shaft 3 to rotate by bending backward or forward, and the screen 6 can rotate along with the rotation of the upper rotating shaft 3 to form an inclined use state or a horizontal folding state.
