Description of the Invention: [Technical Field] The present invention relates to a lifting mechanism and a display device using the same, and more particularly to a lifting mechanism capable of adjusting the height of a display and a display device using the same . [Prior Art] The display system currently uses a fairly common electronic product. In general, the location of the f display is often different depending on the space configuration or user preferences. Therefore, the lifting mechanism for adjusting the height of the display is adapted accordingly. There are many lifting mechanisms for adjusting the height of the display today. In addition to adjusting the height of the display, these lifting mechanisms also have the function of supporting the display. Moreover, most of these lifting mechanisms utilize a combination of a plurality of brackets and a constant force spring to achieve the purpose of adjusting the height of the display. However, most of the brackets of the lifting mechanism are made of steel electrogalvanized cold rolled coil (SECC), which makes the overall mechanism costly to manufacture. In addition, the application of the constant force spring is not only expensive, but also its manufacturing time. The present invention relates to a lifting mechanism and a display device using the same, which utilizes a mutual cooperation of a first threaded sleeve, a second threaded sleeve and a guiding sleeve to adjust the height of the display. 6

In other words, the user can conveniently hold and rotate the handle 650 to further drive the second gear 620 to rotate. Further, the base receiving portion 230 has a recess 232. As shown in Fig. 4B, the first threaded sleeve 300 is placed in the recess 232. Here, Fig. 4B omits the guide sleeve 500 of Fig. 4A to illustrate the position where the first threaded sleeve 300 is placed in the recess 232. As mentioned above, the first gear 320 is part of the first threaded sleeve 3〇〇 and the first gear 320 is engaged with the second gear 620. Therefore, when the second gear 620 rotates, the first gear 32 and the first threaded sleeve 300 are simultaneously rotated. At this time, the first threaded sleeve 3 is rotated along the groove 232. Next, as shown in Section 4C, the first threaded sleeve 300 has an externally threaded surface 310 and the second threaded sleeve 400 has an internally threaded surface 410. The externally threaded surface 31 is threadedly engaged with the internally threaded surface 41. Therefore, when the first threaded sleeve 300 is rotated, the second threaded sleeve 4 is moved. In the present embodiment, the number of threads of the internal thread surface 410 is only required to be several, and κ can cooperate with the external thread surface 310. The number of threads of the externally threaded surface 31 is determined by the lifting stroke of the second threaded sleeve 400 in the lifting direction D1. Please refer to Figs. 4D and 5, and Fig. 5 is a partial enlarged view of Fig. 4D. Among them, Fig. 5 only shows the partial guide sleeve 5 (8). When the first threaded sleeve 300 is rotated, the second threaded sleeve 4 is restricted by the guide sleeve 5', so that the second threaded sleeve 4 is converted from a helical motion to a lifting motion in the lifting direction D1.

The guide rib 54 is disposed on the inner side of the guide sleeve 500, and the guide groove 44 is disposed on the outer side of the second threaded sleeve 400. When the first threaded sleeve 3 is driven to move the second threaded sleeve 400, and the guide rib 540 and the guide groove 44 are engaged with each other, the second crepe sleeve 400 is moved only in the lifting direction []1. In other words, by the cooperation of the guiding rib 540 and the guiding groove 440, the movement of the second threaded sleeve 4 is simplified by the helical motion into a linear motion to drive the display 8 (as shown in Fig. 1) to move up and down. In this way, the display 8 can be raised or lowered by the lifting mechanism 100 < In the present embodiment, the number of the guiding ribs 540 corresponds to the number of the guiding grooves 440. In addition, the guiding sleeve 5〇〇 and the second threaded sleeve 400 of the embodiment each have a plurality of guiding ribs 540 (only one guiding rib 540 can be seen in FIG. 5 due to the viewing angle) and the guiding groove 440. The invention does not limit the number of guide ribs and guide grooves. Referring again to Fig. 5, in the present embodiment, one end of the guide groove 440 has a side wall 442 to prevent the second threaded sleeve 400 from coming off when moving in the lifting direction D1. In addition, when the second thread (the sleeve 4 (9) is raised to the highest position in the lifting direction D1, the side wall 442 can also be used to position the second threaded sleeve 400 at a predetermined position. Further, as shown in FIG. 4D, The embodiment may also provide a buffer positioning post 330 on the upper portion of the first threaded sleeve 300. In addition, a buffer spring 630 is sleeved to the buffering position 枉330 to support the display 800 (as shown in FIG. 1). The buffer spring 630 is in a compressed state to provide a supporting force for supporting the display 800.
