The liquid crystal display has the advantages of small accumulation, light weight, high definition, low light and light, and is widely connected by the market. In addition, in order to increase the usability of the liquid crystal display, it is often necessary to rotate or swing the screen by a certain angle. The rotation or swing function of a liquid crystal display is usually made by a hinge structure: now. A conventional hinge structure includes: a fixing member, a pivot shaft, a plurality of oil-containing cymbals and a fixing member; the fixing member is bent into an l-shaped plate-like structure, and one of the fixing members is provided on the flat plate. a hole, the other plate is provided with a special-shaped limiting hole, the pivot shaft comprises a cylindrical base body, and a central portion of the base body extends toward the side-through shaft, and a parallel plane portion is formed on the through shaft. The other part of the shaft not formed with the flat portion is provided with a thread, and the other part of the base body has a fixing column extending from the middle portion of the base body, and the setting hole is opened on the top portion of the base; the plurality of oil-containing holes are respectively disposed on the fixing member and the shaft Between the base body, the fixing member and the fixing member, the cymbal piece can be synchronously pivoted with the pivoting shaft of the pivot; the through shaft is pierced through the spacer and the fixing member, and is fixedly connected with the fixing member. The hinge structure restricts the rotation angle of the liquid crystal camp by the special-shaped limit hole 'only' the hinge structure is higher for the shaped limit hole and the limit hole is easy to wear, so the limit effect is more than f invention content] In view of this, there is a need for I # effect, U structure Γή m ', a adjustment of the LCD screen angle limit position and the early hinge structure between the structures.

When the display housing 100 is driven, as shown in FIG. 4: rotate. Similarly, the second limiting surface 3313 of the inner surface (1) of the second limit fixing member 抵 is rotated in the direction of rotation, and only the rotating member 20 cannot continue to rotate in the first direction toward the second direction. ° Rotate, so as to drive the display housing 100 15 d厶J leaves. Thus, the limit piece 33 fish ^ /,. The end face 111 of the jaw member 10 and the inner surface 113 cooperate with the limit to achieve the limit function of the door 丄A. In this process, due to the elastic force of the elastic body 37, the holder 25' of the second member 2', the second pulse II32, the limiting piece 33, the rotation in ^ /rj thick "sheet 34, the third friction plate 35, The side plate 13 of the fixing member 10, the spacer 36, the two jaws, 4, ^ ^ - the elastic body 37, the spacer 38 and the locking cow: and generate an axial force 'to make the first friction piece 摩擦 the friction piece 34 and Between the third friction linings % = 3 '" causes the rotating member 20 to remain positioned relative to the stationary member 10. "The freedom of the display housing 100 of the liquid crystal display can be understood as 'the change of the pivot 31 is only required to be a non-circular cross section. The shape of the u shape' is changed accordingly. The same: the pivot of the solid ... 0 The hole 131 has a hole, and the pivot hole 251 of the fixed two can be a circular hole. The pivot 31 can be provided with no external thread 3131, and the lock 3 q χ ^. Not limited to the nut Other locks can be fixed: (4) transfer, riveting, etc. The limit piece 33 3 can be replaced by other snap parts. The cooperation of the buckle portion and the limiting portion makes the limiting piece 33 unable to rotate relative to the rotating member 2〇. The hinged structure fan is not limited to the application of the liquid crystal L 4 S, which can also be used for liquid crystal. On electronic devices such as televisions, notebook computers, and digital cameras, the fixing member 1 is not limited to being fixed on the bottom of the liquid crystal display, 9ΠΠ L· ^ ^ —, or can be fixed to the liquid crystal display. °〇^ — , Correspondingly, the rotating member 20 can also be fixed on the liquid crystal display base 200. In addition, the pivot The components may be only one, and the other junctions are adapted or omitted. The invention is in accordance with the invention patent requirements, and the above is only a preferred embodiment of the present invention. For those skilled in the art, equivalent modifications or branchings in the spirit of the invention should be included in the following patent application.
