Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a lifting mechanism for the height of a lifting mechanism. 100 years. October Z7 day Press, especially for adjusting display [Previous technology] With the wide consideration of computers, Wei is increasing and perfecting, and its volume tends to be thinner and thinner. Since the liquid crystal display device has the advantages of small size and light weight relative to a CRT (Cathode Ray Tube) display, it has gradually replaced the CRT display as a main component of the computer. In order to facilitate the viewing of the liquid crystal display from different perspectives, conventional liquid crystal display devices are usually provided with a lifting mechanism to adjust the height of the liquid crystal display. [0003] As shown in FIG. 1, a conventional lifting mechanism 100 for adjusting the height of a liquid crystal display panel includes a base 10, a lifting block 20, and a coil spring 30. A groove 11 is formed in the base 1 ′. The opposite side rails are disposed in the channel 11 , and the outer edge of the channel 11 is provided with a fixing hole 13 . The lifting block 20 can be inserted into the channel 11 of the base 10 and slidable relative to the base 10. The top end of the lifting block 20 is provided with a connecting portion 21 connected to the liquid crystal display, and the bottom end of the lifting block 20 is provided with two One end of the coil spring 30 is fixed on a shaft 31. The two ends of the shaft 31 are respectively provided with fixing holes 311. The fixing member 33 passes through the fixing hole 311 of the shaft 31 and the fixing hole on the base 10. 13 The shaft 3i is locked to the base 10; the other end of the coil spring 30 is provided with a through hole 32, and the fixing member 36 passes through the through hole 32 of the coil spring 30 and the screw hole 22 of the lifting block 20 The end of the coil spring 30 is locked to the lifting block 20. [0004] In use, the force is applied to press the liquid crystal display 相连 connected to the lifting block 20 so that the 097126405 form bat number A 〇 1 〇 1 page 3 / 18 pages 1003398345-0 1356669 [0005] [0006] [0007 ] 100 years. On October 27th, the position of the lifting block, the weight of the __hand^ screen and the lifting block 20 can be balanced with the friction between the restoring force lifting block 2〇 of the coil spring 3 and the base 10. And positioning the lifting block 2〇; if the liquid crystal display is raised, an upward thrust is applied to the liquid crystal display, and the thrust and the restoring force of the coil spring 30 can overcome the gravity and lifting of the liquid crystal display and the lifting block 20. The friction between the block 20 and the base 10 raises the lift block 20 to a predetermined position. However, the lifting mechanism 100 mainly balances the gravity of the liquid crystal display panel and the lifting block 20 by the restoring force of the coil spring 3, and the coil spring 3 is deformed after being stretched multiple times, thereby causing the volume to be rolled. The spring 3〇 can no longer provide enough restoring force to balance the gravity of the LCD screen and the lifting block. Therefore, the lifting mechanism 100 has a short service life. Further, since the restoring force of the coil spring 3 is substantially constant, only a load of a specific weight can be mounted on the lifting mechanism 100. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a lifting mechanism having a long service life and capable of setting different weight loads. The lifting mechanism includes a bracket, a sliding member and at least one torsion spring.

The fixing hole 5156 of the slide rail 5155 fixes the slider 52 to the top of the inner slide 5155, so that the slider 52 is slidably disposed on the housing 51 0 . The roller 5521 of the roller 552 is then passed through the sliding slot 5121' of the housing 510 and riveted to the connecting piece 5526 so that the roller 552 is slidably mounted in the sliding slot 5121 of the housing 51. Then, the second boss 5513 of the connecting shaft 551 is partially inserted into the engaging hole 5525 of the roller 552. Then, the first protrusion 5512 of the connecting shaft 551 is inserted into the engaging hole 5311 of the connecting member 53, and the fixing member passes through the positioning hole 5321 of the side plate 532 of the connecting member 53 and the positioning hole 5157 of the inner sliding rail 5155, thereby connecting. The piece 53 is fixed to the bottom end of the inner slide rail 5155. A hook 5412 of the first torsion spring 541 is hooked into the annular groove 5514 of the connecting shaft 551. One of the first torsion clams 542 is hooked on the second boss 5513. Then, the screw 564 is passed through the second cymbal 563, the first cymbal 562, the other hook 5412 of the first torsion spring 541, the other first cymbal 562, and the first through hole 5122 of the housing 510. Screw into the screw hole 5612 of the connecting shaft 561. Pass the screw 574 through the spacer 097126405 Form No. A0101? Page/Total 18 pages 1003398345-0 1356669 On October 27th, 27th, the nuclear replacement page 563, the other hook 5422 of the second torsion spring 542, the sleeve 572 and the second through hole 5123 on the casing 510, the screw After being assembled into the screw hole 5712 of the connecting shaft 571, the first torsion spring 541 and the second torsion spring 542 are both disposed on the substrate 512 and substantially parallel to the substrate 512. The sliding member 52 and the connecting member 53 can slide along the outer sliding rail 5151 together with the inner sliding portion 51 55 to drive the first connecting component 55 to slide along the sliding slot 5121 of the housing 510 to change the first torsion spring 541. And the degree of distortion of the second torsion spring 542, thereby changing the torsion of the first torsion cyanine 541 and the first torsion cyanine 542. Moreover, since the third connecting component 57 includes the sleeve 572, the first torsion spring 541 and the second torsion spring 542 can be spatially offset by a certain distance, thereby preventing the first torsion spring 541 and the second twisting cyan 542 from being in the sliding member. Interference occurred during the sliding of 52. [0021] Referring to FIG. 2 to FIG. 4, when the height of the liquid crystal display panel 41 is adjusted by using the lifting mechanism 50, it is only necessary to apply a downward or upward force to the liquid crystal display panel 41 so that the sliding member 52 is opposite to the bracket. 51 sliding, when the slider 52 is moved to the predetermined position, the application of the force to the liquid crystal display 41 is stopped, the torque of the sliding member 52 at the first torsion spring 541 and the second torsion spring 542, the inner slide rail 5155 and the outer slide rail 5151 The friction between the slider 52, the connecting member 53 and the gravity of the liquid crystal display 41 is balanced to stop at the predetermined position. [0022] Compared with the conventional lifting mechanism, the sliding member 52 of the lifting mechanism 50 is slidably disposed on the bracket 51 by the sliding group 515, and by the first twisting yellow 541 097126405 and the second torsion spring 542 It is connected to the bracket 51, so that during the sliding of the sliding member 52, the two hooks of the first torsion spring 541 or the second torsion spring 542 are close to or away from each other within a certain angle range, and can be used for a long time without forming a form number.

In addition, by changing the lengths of the hooks 5412 and 5422 of the first and second torsion springs 541 and 542, the magnitude of the torsion arm of the first torsion spring 541 or the second torsion spring 542 can be changed, so that the lifting mechanism 50 can be Loads of different weights are mounted on the slider 52. In addition, the first torsion spring 541 and the second torsion spring 542 are both disposed on the substrate 512 and substantially parallel to the substrate 512. Therefore, the housing 510 only needs to have a small thickness, that is, the housing 510 can be thinned. In addition, the lifting mechanism 50 is mainly used with the sliding mechanism 515, the sliding member 52, the connecting member 53, the first torsion spring 541 and the second torsion spring 542 as lifting elements, and has a simple structure. Easy to assemble. [0023] It can be understood that the lifting mechanism 50 of the present invention may also include only a torsion spring, and only the two ends of the torsion spring need to be connected to the connecting member 53 and the bracket 51 respectively. The lifting mechanism 50 may also include the connecting member 53 and directly connect the first torsion spring 541 and the second torsion spring 542 to the slider 52. In addition, the lifting mechanism 50 may also include only a group of slides, and the sliding member 52 is disposed on the sliding group.
