The liquid crystal display is small in size, light in weight, high in definition and low in light, and is widely accepted by the market. $, in order to increase the convenience of use of the liquid crystal display, it is often necessary to rotate or swing the liquid crystal display at a certain angle. The rotation or swing function of the liquid crystal display is usually realized by a hinge structure. For example, a conventional hinge structure includes a fixing member, a pivot shaft, a plurality of cymbals and an H component; the fixing member is bent into an l-shaped plate-like structure, and the fixing member has a hole formed therein. The other plate has a bottom-shaped limiting hole; the pivot shaft comprises a cylindrical base body, and a central portion of the base body has a through-axis extending from the side: a through-axis is formed on the shaft, and the through-shaft is not formed. The other part of the flat portion is provided with a thread, and the base body is further provided with a fixing column extending from the central portion, and the fixing column is provided with a mounting hole, and the plurality of cymbals are provided with oil-containing holes, and are respectively disposed on the fixing member and 2 Between the shaft base member and the fixing member, the spacer can be synchronously pivoted with the pivot shaft of the pivot, and the through shaft passes through the shaped limiting hole ' of the cymbal and the fixing member and is fixedly connected with the fixing member. The hinge structure restricts the rotation angle of the liquid crystal display by the special-shaped limiting hole.

One side of the spacer is provided with a profiled surface, and the latching cymbal-side is provided with a profiled surface, which cooperates with the profiled surface of the spacer. Compared with the prior art, the hinge structure does not adopt a special-shaped limit hole limit method with high precision and easy wear, but opens a limit groove on the y-axis to set a limit block on the rotating member.

At this time, the pivot 301 is inserted from the outer side of the side plate 24 of the rotating member 20 into the pivot hole 241 of the rotating member 20 and the fixing member 10. The shaft hole 141 is deformed, and the limiting block 244 of the rotating member 20 is received in the limiting groove 3013 of the pivot 301. The deforming shaft portion 3012 of the pivot 301 is engaged with the deforming shaft hole 141 of the fixing member 10, and thus the pivot 301 It cannot rotate relative to the fixing member 10. Then, a spacer 306 of a pivoting assembly, a friction pad 307, and a second elastic body 308 are sequentially disposed. The other friction pad 307 is sleeved onto a pivot 301, and the two elastic bodies 308 are provided back to back. Finally, the locking member 309 is fixed to the pivot 301 by a screw connection, whereby the pivoting assembly is assembled and the other pivot The spacer spacer 306 of the rotary assembly, the friction pad 307, the elastic body 308 and the fastener 309 are assembled in the same manner. When the hinge structure 300 is mounted on the liquid crystal display, the fixing member 10 is fixed to the fixing hole 10 by its mounting hole 122 On the base 200 of the liquid crystal display, the rotating member 20 is fixed to the display screen housing 100 of the liquid crystal display by its mounting hole 222. During operation, the display screen housing 100 of the liquid crystal display is pulled, the display screen housing 100 drives the rotating member 20 to rotate, and the fixing member 10 is fixed relative to the base 200 of the liquid crystal display, when the display screen housing 100 faces the first direction (shun When the hour hand is rotated to the first limit position, as shown in FIG. 3, the limiting block 244 of the rotating member 20 abuts against the first limit 14 1321719 in the limiting slot 3013 of the pivot 301 =: . Can not be relative to the hub, $ dry, and because the pivot 301 and the fixed member - the rotating member 20 can not be relatively fixed relative to the fixed member 1 疋, so this can be in the opposite direction to the direction (reverse time: 2 continue to rotate, only the second limit position, as shown in Figure 4, the limit block, in the rational, in the second limit position of the limit slot 3013, then turn two: can not be along the second The direction continues to rotate, and can only be fixed in the opposite direction - the direction is rotated by the combination of the limit block ice-direction phase, which can better limit the rotation of the rotating element 2::= degree' to better limit The display case is 〇〇2. In the process, due to the elastic force of the elastic body 308, the angle of each pad is sin and an axial force is generated, so that a large friction between the pads is generated. The relative fixing member 1〇 can be maintained in the adjusted position::,: The free display position of the display screen housing 100 of the liquid crystal display device. 二. 2:: cut, the deformed shaft portion 3012 of 301 can have other shapes. For the non-zero section, the hole corresponding to the corresponding one can be changed accordingly. The external thread 3016 can be omitted on the pivot 301, and the lock is fixed. The piece 309 is not limited to the mother's. It can also be replaced by other locks. It can also be fixed by welding, splicing, etc. The hinge structure 300 is not limited to the application & night crystal display, it can also be used for LCD TV, notebook computer and digital On the electronic device such as a camera, the fixing member 10 is not limited to being fixed to the base 2 of the liquid crystal display, and may be fixed on the display screen housing 1 of the liquid crystal display. Correspondingly, the rotating member 20 may also be fixed to the liquid crystal display. In addition, the pivoting assembly may be only one, and other structures are adapted or omitted. 15 1321719.
