[Prior Art] Please refer to Fig. 1, which is a schematic view showing a conventional manner of displaying a screen. As shown in Fig. 1, the display screen 10 is usually arranged with the base 11 to be stably placed on the table top. The base 11 can be composed of a sleeve 12, a support column 13 and a bottom plate 14, wherein the sleeve 12 is mostly slidably coupled with the support column 13 to drive the display screen 10 to move up and down relative to the support column 13 by the sleeve 12. For the purpose, the support column 13 is disposed on the bottom plate 14, and the weight of the entire display screen 10 is carried by the bottom plate 14. However, since the sleeve 12 is mounted on the back side of the display screen 10, the center of gravity of the display screen 10 falls in front of the bottom plate 14. When the area of the bottom plate 14 is too small, it is easy to cause a safety problem of displaying the forward tilt of the screen. It is therefore common practice to increase the area of the bottom plate 14 to stabilize the support of the base 11 for the display screen 10. The increase in the area of the bottom plate 14 not only increases the material and manufacturing cost of the susceptor 11, but also takes up space. In addition, since the design of the sleeve 12 can only move the display screen 10 up and down, when the user thinks that the viewing angle is not good and wants to adjust the rotation angle of the display screen 10, it is not possible.

The two ends of the constant force spring 234 are respectively connected to the display screen 20 and the outer slide rail 232, and the two ends of the constant force spring 244 are connected to the display screen 20 and the outer slide rail 242. The constant force springs 234, 244 are used to provide a thrust to balance the weight of the display screen 20. In the normal state, since the thrust of the constant force springs 234, 244 is equal to the gravity of the display screen 20, the display screen 20 can be stably placed on the elevating mechanism 21. When the user wants to adjust the height of the display screen 20, the height of the display screen 20 relative to the susceptor 22 can be adjusted by applying a force to the display screen 20. For example, the user can apply force to the display screen 20 and match the gravity of the display screen 20 to overcome the thrust of the force springs 234, 244, so that the display screen 20 moves downward to shorten the distance from the base 22. Or the user can apply force to the display screen 20 and combine the thrust of the force springs 234, 244 to overcome the gravity of the display screen 20, thereby moving the display screen 2〇 upward. The connection relationship between the components in the elevating mechanism 21 will be described in detail below with reference to the drawings. Please refer to Figures 3A to 3B at the same time.

When assembled, the outer slide rail 232 can be first combined with the support arm (2). This step can be achieved by fixing the bolt 231B through the outer slide rail 232 and the support arm 221 and then locking the nut 231A. At this time, the outer slide rail 232 is rotatable relative to the support arm 221 . Next, the inner slide rail 233 can be placed in the outer slide rail 232. And so on, the outer slide rail 242 and the inner slide rail 243 are assembled. The two sides of the plate 250 have a bent design for attachment to the outer slides 232, 242, the function of which will be described in detail below. As shown in FIG. 3B, after the assembly is completed, as shown in FIG. 3B, the outer slides 232, 242, the inner slide rails 233, 243, and the baffle 250 can be simultaneously configured by the pivot axis of the rotating portions 23, 241. The inner slide rails 233, 243 are slidable relative to the outer slide rails 232, 242. The display screen 2 is connected to the two inner slide rails 233, 243 by its two sides. For the relationship between the other parts of the lifting mechanism 21, please refer to Figures 4A to 4B. Figure 4A shows a partial exploded view of the sliding positioning portion of Figure 2, and Figure 4B shows the assembled view of the parts of Figure 4A. . As shown in FIG. 4A, the lifting mechanism 21 further includes a first fixing plate 251 and a second fixing plate 252, wherein the first fixing plate 251 is fixed to the lower edge of the display screen 2, and the second fixing plate 252 is It is used to install the force springs 234, 244. The sliding positioning portion 230 further includes a roller 235 and a spacer 236, and the sliding positioning portion 240 further includes a roller 245 and a spacer 246. The rollers 235, 245 are mainly mounted on the second fixing plate 252, and the spacers 236, 246 are mounted on the first fixing plate 251. The assembly relationship of the parts is explained below.

One end of the constant force spring 234 is mainly disposed on the drum 235, and a joint member (not shown) can pass the hole 252A on the second fixing plate 252 and the hole 235A in the drum 235 to make the force spring 234 The end is fixed to the second fixing plate 252 by the roller 235 and the connecting member (not shown), and the winding end 234 of the constant force spring 234 is fixed on the playing board 250 (see FIG. 3B). The spacer 236 is fixed to the first fixing plate 251 by a hole 251A in the first fixing plate 251. Since there is a space between the fixed force spring 234 and the first fixing plate 251, when the winding end 234A of the constant force spring 234 is stretched or pushed by the force, it is very easy to pull the structure of the entire constant force spring 234 and damage. Force spring 234. Thus the arrangement of the spacers 236 effectively holds the constant force spring 234 in a fixed position. As for the assembly of the constant force spring 244 and the spacer 246, and so on. When the constant force springs 234, 244 are fixed to the second fixing plate 252, and the spacers 236, 246 are fixed to the first fixing plate 251, the first fixing plate 251 and the second fixing plate 252 can be assembled together. Figure 4B shows. After the two sides of the screen 20 to be displayed are combined with the inner slide rails 233, 243 (see Fig. 3B), the components of the Fig. 4B can be combined with the display screen 2'. The winding ends 234A and 244A of the constant force springs 234 and 244 are fixed on the baffle 250 (see FIG. 3B). Since the plate 250 is fixed on the outer rails 232 and 242, the force springs 234 and 244 are fixed. One end can be indirectly fixed to the outer rails 232, 242. Thereby, the two ends of the constant force springs 234 and 244 are respectively fastened to the display screen 20 and the outer slide rails 232 and 242. Of course, in addition to the sliding design of the inner and outer slide rails as the display screen, the first tubular member and the second tubular member that are sleeved together can also be used as the sliding device.

For the operation of the lifting mechanism, please refer to the figures f 5a to 5c, 6a to 6c, which is a side view showing the system in operation. As shown in FIG. 5, the display screen 20 has a predetermined position p on the base 22. Preferably, when the display screen 20 is located at the predetermined position p, the center of gravity of the display screen 20 is substantially two. The rotating portions 231 and 241 (not shown in FIG. 5A) are arranged in a line. At this time, no matter whether the display screen 2 is rotated clockwise (see Fig. 5B) or counterclockwise (see Fig. 5C), no additional torque is applied to the base 22. Of course, the setting mechanism of the lifting mechanism 21 causes the rotation and movement of the display screen 20 to be two independent movements. Therefore, as shown in FIG. 6A, the user can also adjust only the height of the display screen 20 to display the screen 2〇. Moving downward relative to the base 22 to the position P', and rotating the angle of the display screen 20, as shown in Figs. 6B to 6C.

At the same time, the present invention has the advantage of material saving as compared to the conventional increase in the floor area to increase the stability. The elevating mechanism and the display system using the same disclosed in the above embodiments of the present invention control the movement of the display screen by the sliding positioning portion of the elevating mechanism and rotate the display screen back and forth by the rotating portion.
