The folding of existing notebook computer is as opening the book mostly, can not adjust the far and near relation of height between display screen phase adversary and the eyes, unique adjustable be the angle of opening, therefore as user during at the use working with notebook computer, usually be limited by the low excessively influence of screen position, can not be with correct body position work, but long-time croucs work, can make a big impact to the healthy of user, the lighter can make the user produce the sensation of having a pain in the back, weight person bends over one's desk working owing to bowing for a long time, make cervical vertebra be in flexing position or some special body position for a long time, not only make the increased pressure in the cervical intervertebral disk, and make musculi colli be in non-coordination stress for a long time, nape muscle and ligament are subject to the tractive strain, anterior margin of vertebral body is worn and torn mutually, hyperplasia, add and reverse, lateroflexion is excessive, further causes damage, is easy to take place cervical spondylopathy.
In order to address the above problem, the someone has proposed some and has regulated the apparatus and method of display screen height and angle, for example, in patent publication No. is in the Chinese patent application document of CN1506790A in disclosed a kind of notebook computer with adjustable LCD, the height and the angle of regulating display by a supporting and adjusting device that is arranged on the main frame.This supporting and adjusting device comprises two support bars that are arranged on the main frame both sides, and display is installed on two support bars, can the swing adjusting angle, and the height by the slidable adjustment display of support bar in display simultaneously.Because display is to regulate by swing between two support bars and slip, so the safety-type of its operation and stable not high enough, the layout of cable also has certain difficulty.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of Liftable type turning gear that can regulate the indicator screen height is provided simple to operationly, and this Liftable type turning gear is particularly useful for regulating the notebook computer display screen.
Liftable type turning gear of the present utility model comprises,
One first support member, one second support member, one the 3rd support member and an end fixture, between the end fixture and first support member, be provided with one first rotating shaft, between first support member and second support member, be provided with one second rotating shaft, between second support member and the 3rd support member, be provided with one the 3rd rotating shaft, integrally constitute a linkage that can rotate folding thus.
Liftable type turning gear of the present utility model also further comprises a swinging mounting, and mounting end fixture in the rotating shaft of swinging mounting makes that whole linkage can be around the rotating shaft rotation of swinging mounting.
Whole linkage has certain included angle between the direction of the direction of the rotating shaft of swinging mounting rotation and whole linkage folding lifting, generally be approximate vertical.
End fixture or swinging mounting can be fixed on the object as base, and the folding by linkage comes lifting to be installed in any object on the 3rd support member.
Liftable type turning gear of the present utility model can be used for notebook computer, and its medial end portions fixture or swinging mounting are fixed on the main frame base, and the display screen of notebook computer is installed on the 3rd support member.
Display screen height by Liftable type turning gear adjusting notebook computer of the present utility model makes the user can obtain a reasonable visual experience, alleviates the discomfort impression that the user uses notebook computer.

Embodiment
Below in conjunction with specific embodiment shown in the drawings the utility model is described further.
Fig. 1 shows one first embodiment of Liftable type turning gear of the present utility model.As shown in Figure 1, this Liftable type turning gear comprises: one first support member 2, one second support member 3, one the 3rd support member 4 and an end fixture 1, between the end fixture 1 and first support member 2, be provided with one first rotating shaft 5, between first support member 2 and second support member 3, be provided with one second rotating shaft 6, between second support member 3 and the 3rd support member 4, be provided with one the 3rd rotating shaft 7, integrally constitute a linkage that can rotate folding thus.Its operation realizes being on the whole the rotation folding condition of " it " font hinge, at this moment, referring to Fig. 2 (this moment, linkage was a closure state), first support member 2 can be done turn clockwise (arrow A direction) around end fixture 1 by rotating shaft 5, second support member 3 can be done around first support member 2 by second rotating shaft 6 and be rotated counterclockwise (arrow B direction), the 3rd support member 4 can be done rotation (arrow C direction) around second support member 3 by the 3rd rotating shaft 7, realize the rotation folding of hinge successively, thereby play the purpose of regulating the height that is installed in the notebook computer display screen 11 on the 3rd support member 4.
Fig. 3 shows one second embodiment of Liftable type turning gear of the present utility model.As shown in Figure 3, this Liftable type turning gear is different with the Liftable type turning gear among first embodiment to be also to comprise a swinging mounting 8, mounting end fixture 1 in the rotating shaft 9 of this swinging mounting 8, make that whole linkage can be around rotating shaft 9 rotations of swinging mounting 8, the people around for example screen content can being showed.State shown in Figure 3 is whole linkage is approximately perpendicular to whole linkage folding lifting around the direction of rotating shaft 9 rotations of swinging mounting 8 a direction.Shown in Figure 4 is the state of linkage when closed.
This Liftable type turning gear can be applied in to be needed to regulate on the device or equipment of height, this moment, end fixture 1 or swinging mounting 8 can be fixed on the object as base, and the folding by linkage comes lifting to be installed in any object on the 3rd support member 4.One of them application is the height at notebook computer adjusted display screen.As shown in Fig. 5 A, Liftable type turning gear of the present utility model is installed between the main frame base 10 and display screen 11 of notebook computer, its medial end portions fixture 1 (or swinging mounting 8, not shown in the figures) be fixed in the main frame base 10, the display screen 11 of notebook computer is installed on the 3rd support member 4.
Have groove 12 in the main frame base 10, can be accommodated in after the linkage closure in this groove 12, make notebook computer be in common user mode, shown in Fig. 5 B.
The closed hinge of this " it " font hinge in the Liftable type turning gear of the present utility model lies in the base and what difference is traditional notebook do not have, and display screen is the same with traditional notebook, can realize 180 ° of foldings.Just when the user need adjust screen height, only need " it " font hinge is pulled out in base, can adjust flexibly and use height, thereby play the purpose of improving result of use from ergonomics, and the architecture design of " it " font hinge makes the height control of screen not influence the rotation of screen, thus this height adjustment mechanism use more convenient flexibly.
