In addition, the friction plate 38 can extend a bending piece 42 which can interfere with the second side S ₂ of one of the pulling ends 26 as the switching lever 40 moves relative to the upright frame 16 , thereby generating Further, the effect of the frictional force generated between the friction adjuster 22 and the pulling end 26 is increased, wherein as shown in Fig. 4, the first side S ₁ is opposed to the second side S ₂ . It should be noted that, as shown in FIG. 3, at least one positioning convex portion 37 (shown in FIG. 3, but not limited thereto) may be formed in the switching slot 36 to generate the switching slot 36. The effect of the switching lever 40 is positioned.

Further, apparent from FIG. 4, the contact friction plate 38 pulls a first end 26 of one side S ₁ on contact surface 39 may be formed with a microstructure 44-point contact, so that the friction plate 38 and the frictional contact between the pull end 26 It can be changed from the surface contact to the point contact, so that the sliding of the sliding seat 20 along the height adjusting groove 24 can be made smoother and smoother.

Here, the operation of the friction adjuster 22 will be described. Referring to FIG. 4 and FIG. 5, FIG. 5 is a partial cross-sectional view showing the position where the friction adjuster 22 of FIG. 4 is moved to partially interfere with the pulling end 26. . When the user wants to additionally mount related peripheral components (such as an external touch screen, etc.) on the display screen 12, the user only needs to move the push switch lever 40 in the switching slot 36 as shown in FIG. The position is such that the frictional force adjuster 22 can be pulled and pulled by the friction plate 38 being in contact with the first side S _{1 of the} pulling end 26 and the bending piece 42 and the second side S _{2 of the} pulling end 26 are in contact with each other. The end 26 generates a frictional force to form an upward force together with the fixed elastic force provided by the constant force spring 18 to overcome the weight of the display screen 12 and the weight of the peripheral components to which it is mounted, thereby forming a downward force, thereby displaying The screen 12 and the peripheral components to which it is mounted can be in a static equilibrium state and can be positioned at any height to allow the user to still adjust the display screen 12 on which the peripheral components are mounted on the upright frame 16 without segmentation. The relative height thereof effectively solves the problem that the height adjustment function of the upright frame mentioned in the prior art fails due to the excessive weight of the display screen on which the peripheral components are mounted.

In addition, as can be seen from FIGS. 4 and 5, the design of the movable switching rod 40 can be moved in the switching slot 36, and the user can selectively push the switching lever 40 in the switching slot 36 from FIG. The position is moved to a position where the friction plate 38 and the bending piece 42 partially abut against the pulling end 26 (for example, the position shown in FIG. 5), so that the user can elastically adjust the friction adjuster 22 and pull. The purpose of the friction generated between the ends 26 is to ensure that the display device 10 can utilize friction when different display screens of different weights are displayed on the display screen or the screen 12 is additionally mounted with different weights of peripheral components. The force adjuster 22 provides a suitable friction force to the pull end 26 of the constant force spring 18 so that the user can smoothly perform the screen height adjustment operation of the display device 10.

On the other hand, in another embodiment, the switching slot 36 can be modified to allow cutting The shifting lever 40 is moved to extend the elongated design of the slot of the friction plate 38 and the bending piece 42 completely separated from the pulling end 26, whereby the user wants to directly adjust the display screen without mounting any peripheral components. 12 at the relative height of the upright frame 16, the user can push the switching lever 40 to move from the position shown in FIG. 4 in the switching slot 36 to completely separate the friction plate 38 from the bending piece 42 and the pulling end 26. The position of the display device 10 can be used to perform the positioning of the display screen 12 only by the fixed elastic force provided by the constant force spring 18, thereby preventing the sliding seat 20 from sliding due to the excessive frictional force provided by the frictional force adjuster 22. It does not happen or even can not slide along the height adjustment slot 24.

It is worth mentioning that the present invention may also adopt other designs that utilize the friction adjuster to be movably disposed in the upright frame to at least partially resist or separate from the pulling end of the constant force spring to provide additional friction. For example, Please refer to FIG. 6 , FIG. 7 , and FIG. 8 .

FIG. 8 is an enlarged schematic view of the frictional force adjuster 22' of FIG. 6 against the pulling end 26 of the constant force spring 18, wherein the frictional force adjuster 22' and the upright frame 16 are clearly shown. The structural design, the pulling end 26 is shown in phantom in Figure 8. The elements described in this embodiment are the same as those described in the above embodiments, and they have similar functions or structures, and will not be described again.

As shown in FIGS. 6 , 7 , and 8 , the display device 10 ′ includes a display screen 12 and a support mechanism 14 ′.

The adjuster 22', a through hole 46, and at least one positioning slot 48 (two shown in FIG. 8, but not limited thereto), the friction adjuster 22' can be a latch and can be movably disposed In the through hole 46, the friction adjuster 22' may have at least one positioning rod 23 (two shown in FIG. 7, but not limited thereto), and the through hole 46 is formed on the upright frame 16 and with the force spring 18 The pull end 26 is opposite, the positioning slot 48 extends from the through hole 46, whereby the friction adjuster 22' is opposed to the upright frame When the 16 is rotated until the positioning rod 23 is aligned with the positioning slot 48, the friction adjuster 22' can penetrate the through hole 46 and contact the pulling end 26 of the constant force spring 18.

In addition, as shown in FIG. 8 , the supporting mechanism 14 ′ may further include at least one fastening structure 50 (two shown in FIG. 8 , but not limited thereto), and the fastening structure 50 may be formed on the vertical frame 16 . And adjacent perforations 46, in more detail, in this embodiment, the fastening structure 50 can include two protruding ribs 52, and the two protruding ribs 52 can be arranged in parallel to jointly clamp the positioning rod of the friction adjuster 22'. 23, whereby when the friction adjuster 22' contacts the pulling end 26 of the constant force spring 18, the user can rotate the friction adjuster 22' to the positioning rod 23 to engage with the two protruding ribs 52 and the positioning groove The holes 48 are misaligned so that the friction adjuster 22' can be securely attached to the upright frame 16.

Here, the operation of the friction adjuster 22 ′ will be described. Referring to FIG. 8 and FIG. 9 , FIG. 9 is the friction adjuster 22 ′ of FIG. 8 rotated until the positioning rod 23 is engaged with the fastening structure 50 . An enlarged schematic view of the misalignment with the positioning slot 48. When the user wants to additionally mount related peripheral components (such as an external touch screen, etc.) on the display screen 12, the user only needs to rotate the friction adjuster 22' (such as using a screwdriver or the like) relative to the upright frame 16 Rotating to the positioning rod 23 aligns with the positioning slot 48 and then pushes the friction adjuster 22' through the perforation 46 and contacts the pulling end 26 of the constant force spring 18 (as shown in Figure 8). Finally, the user only needs to rotate the friction adjuster 22' relative to the upright frame 16 to the position where the positioning rod 23 as shown in FIG. 9 is engaged with the two protruding ribs 52 and is displaced from the positioning slot 48 to be positioned. The friction adjuster 22' thus completes the operation of the display device 10' to provide frictional force to the pull end 26 of the constant force spring 18 using the friction adjuster 22'.

In this way, through the friction adjuster 22' contacting the design of the pulling end 26 of the constant force spring 18, the friction adjuster 22' can generate friction with the pulling end 26 to be combined with the fixed elastic force provided by the constant force spring 18.

On the other hand, if the user wants to directly adjust the relative height of the display screen 12 on the upright frame 16 without mounting any peripheral components, the user can rotate the friction adjuster 22' relative to the upright frame 16 The position as shown in Fig. 9 is rotated to the position where the positioning rod 23 as shown in Fig. 8 is aligned with the positioning slot 48, and then the friction adjuster 22' is pulled out from the through hole 46 to no longer contact the force spring 18 The pulling end 26 is such that the display device 10' can perform the positioning of the display screen 12 only by the fixed elastic force provided by the constant force spring 18, thereby avoiding the excessive friction provided by the friction adjuster 22'. This causes the sliding seat 20 to slip or not even slide along the height adjusting groove 24.

Compared with the prior art, the present invention adopts a design in which a friction adjuster is movably disposed in an upright frame to selectively at least partially interfere with or separate from the pulling end of the constant force spring to achieve elastic operation of the user. The force adjuster provides additional friction to the pulling end of the constant force spring, so that the display device of the present invention can still be provided by the friction adjuster even in the case where the display screen is additionally loaded with peripheral components Appropriate friction force to the pulling end of the constant force spring, so that the user can smoothly perform the height adjustment operation of the display screen, thereby effectively solving the height adjustment function of the upright frame mentioned in the prior art due to the display of the peripheral components mounted thereon The problem that the overall weight of the screen is too heavy and fails, whereby the present invention can greatly improve the operational convenience of the display device in adjusting the height of the display screen.
