The second spacer 309 is placed at the limiting slot 162 of the fixing member 10, so that the second spacer 309 of the second spacer 309 is locked in the limiting slot 162, and the fixing piece 3092 is locked to the fixing member. The two spacers 3091 are in close contact with the first limiting surface 1621 and the second limiting surface 1622 of the limiting slot 162, respectively, so that the second spacer 309 is fixed to the fixing member 10. Then, the third spacer 310 is placed at the locking groove 244 of the rotating member 20, so that the blocking block 3102 is resisted in the locking groove 244 of the rotating member 20, so that the third spacer 310 cannot be opposite to the fixing member 10 Turn. Then, the threaded portion 3111 of the limiting member 311 is engaged with the threaded hole 3014 13 200806157 w opened on the pivot 301 to fix the limiting member 311 to the pivot 301. Then, the rotating member 20 is disposed corresponding to the fixing member 10, so that the deformation hole 242 of the rotating member 20 is aligned with the pivot hole 161 of the fixing member 10, and the two side plates 24 of the rotating member 20 are located outside the holder 16 of the fixing member 10. At this time, the boring shaft 301 is inserted into the deformation hole 242 of the rotation 20 and the pivot hole 161 of the fixing member 10 from the outside of the support 16 of the fixing member 10, and the deformation of the first deformation shaft portion 3012 of the pivot 301 and the rotating member 20 The hole 242 is engaged, so that the pivot 301 cannot rotate relative to the rotating member 20, and the limiting member 311 fixed to the pivot 301 is received in the limiting slot 162; then, a first friction pad 303 and two elastic bodies are sequentially disposed. 304, a second friction pad 305, a torsion spring 302 and a limiting spacer 306 are sleeved on a pivot 301, the two elastic bodies 304 are provided back to back, and the first fixed end 3021 of the torsion spring 302 is erected in the previous assembly. The second fixed end 3022 of the fixing member 10 is disposed at the limiting block 3062 of the limiting spacer 306; finally, the locking member 307 is fixed to the pivot 30 by a screw connection, thereby The pivoting assembly is assembled and the other pivoting assembly is assembled in the same manner. The torsion spring 302 is provided with a pre-tightening force, a first spacer 308, a first friction pad 303, an elastic body 304, a second friction pad 305, a torsion spring 302, a limit pad 306 and a lock 307. Closely in turn. After the hinge structure 300 is assembled, the pivot 301, the third spacer 310, the first friction pad 303, the elastic body 304, the second friction pad 305, the limiting pad 306 and the locking member 307 are opposite to the rotating member 20 The first spacer spacer 308 and the third spacer spacer 310 are fixed relative to the fixing member 10. When the hinge structure 300 is mounted on the liquid crystal display, the fixing member 10 is fixed to the base 200 of the liquid crystal display by the mounting hole 122 thereof, and the rotating member 20806157 is fixed to the display of the liquid crystal display by the mounting hole 222 thereof. On the curtain housing 100. During operation, the display screen housing 100 of the liquid crystal display is pulled, and the display screen housing 100 drives the rotating member 20 to rotate. The second deforming shaft portion 3013 of the pivot shaft 301 cooperates with the deformation holes 3031, 3051 and 3061. A friction washer 303, a second friction washer 305 and a limit washer 306 rotate with the rotating member 20, and the limiting washer 306 causes the second fixed end 3022 0 of the torsion spring 302 to rotate with the rotating member 20 The torsion force of the spring 302 is changed, and the torsion force of the torsion spring 302 is increased or decreased due to the rotation direction of the rotating member 20. This prevents the display housing 100 from driving excessively when the rotating member 20 is rotated, which is advantageous for keeping the hinge structure 300 stable. The fixing member 10 is fixed to the base 200 of the liquid crystal display. When the display screen housing 100 is rotated to the first limit position, as shown in FIG. 3, the limiting member 311 is abutted against the first limiting surface 1621 of the limiting slot 162. The spacer 3091 of the second spacer 309 is fixed. Therefore, since the first limiting surface 1621 is fixed in position, the rotating member 20 can only rotate in the opposite direction to the previous direction. Similarly, in the second extreme position, As shown in FIG. 4, the limiting member 311 abuts against the other spacer 3091 of the second spacer 309 located on the second limiting surface 1622 of the limiting slot 162, so that a better limiting effect can be achieved. During this process, the first spacer 308, the first friction pad 303, the elastic body 304, the second friction pad 305, the limit pad 306 and the lock 307 are closely abutted due to the elastic force of the elastic body 304. The axial force is generated, and a large frictional force is generated between the first spacer 308, the first friction pad 303, the elastic body 304, the second friction pad 305, and the limiting pad 306, so that the rotating member 20 The relative fixing member 10 can be maintained at the adjusted position, 15 200806157, that is, the free positioning of the display screen housing 100 of the liquid crystal display. It can be understood that the first deforming shaft portion 3012 and the second deforming pumping portion 3013 of the pivot 301 can have other shapes, and only need to be a non-circular cross section. The external drawing 3〇15 is not provided on the pivoting 3〇1, and the locking member 3〇7 is not limited to the nut, and may be replaced by other locking members, and may be fixed by splicing, riveting or the like. The hinge structure 300 is not limited to use on a liquid crystal display, and can also be used in electronic devices such as liquid crystal televisions, notebook computers, and digital cameras. The fixing member is not limited to being fixed to the base of the liquid crystal display, and may be fixed to the display screen housing of the liquid crystal display. Correspondingly, the rotating member 2 is also fixed to the base 200 of the liquid crystal display. The mortise lock 4 〇 can be another resisting member 'only need to pass through the locking hole M3 of the holder 16 of the fixing member 1G, ^ one end is received in the pin hole 163' and the other end is abutted against the fixing member It can be used in the fixing groove 144 of the side 142. In addition, the tow component can be only one, while other structures are adapted or omitted. • [Simple diagram description]
