Embodiment
Seeing also Fig. 1～3, is the schematic representation of preferred embodiment of the present invention.Coating type pivot device of the present invention comprises an axle 1 and a coating member 2, and this coating member 2 is sheathed on axle 1 with the axle sleeve 20 of a hollow, and the outer periphery of axle sleeve 20 are provided with an axially open 21.Please cooperate and consult Fig. 4, one side of opening 21 is provided with an extension piece 22, this extension piece 22 extends coating toward the opposite side of opening 21, and the opposite side of opening 21 forms the short slot 23 of a ccontaining extension piece 22 with respect to extension piece 22 places, and has opening 24 between extension piece 22 ends and the short slot 23, in present embodiment, this extension piece 22 is middle sections of being located at coating member 2 with short slot 23.This axle sleeve 20 is provided with a fixed plate 25 in the side extension that short slot 23 is set, and this fixed plate 25 is provided with fixed hole 26, in order to pivot device is fixed to the body of cover-lifting type electronic device.And an end of coating member 2 is provided with a protuberance 27.
This axle 1 is provided with an outstanding stop block 11 with respect to the position of protuberance 27, and movable block is in this protuberance 27.One end of axle 1 is provided with a flange 12, and a side of flange 12 is provided with a junction 13, and this joint 13 can be connected and fixed with a fixed base (figure does not show), on the screen that is fixedly held to cover-lifting type electronic device; Or be connected with another rotating shaft via fixed base.The other end of this axle 1 is provided with a catching groove 14, one fastening pieces 30 and is fastened on this catching groove 14, axially comes off to prevent coating member 2.
The present invention coats by the extension of extension piece 22, and the scope of coating is increased above 360 degree, and the state of fastening that covers in the screen counter-rotating can make torsion more improve.When the positive turn-off of screen opened, axle 1 was extended the opposite direction rotation that coats toward extension piece 22, and axle sleeve 20 is unclamped, and forms lower torsion, opens and be able to lighter strength.Open to an angle when lifting, these stop block 11 blocks are in this protuberance 27, and limit the angle of its unlatching, as shown in Figure 5.And when the screen counter-rotating covers, axle 1 is extended the direction that coats towards extension piece 22 and is rotated, axle sleeve 20 is fastened, because making, extension piece 22 coats the angle increase, torsion is more improved, the effect of Guan Chong is more obvious, and has increased the difference value of clockwise and anticlockwise torsion greatly, thereby has promoted the effect of easy opening and heavy closing.
See also Fig. 6～7, it is the second embodiment of the present invention, this extension piece 22 is extended by a side direction opposite side of axially open 21, and extension piece 22 is located at the two ends of hollow shaft housing 20 and is formed two extension pieces, the opposite side of opening 21 then forms the short slot 23 of two ccontaining extension pieces 22, and also is formed with opening 24 between the end of extension piece 22 and the short slot 23.The opposite side of these axle sleeve 20 openings 21 is extended with a fixed plate 25.
