Description

Technical Field

[0001] The utility model relates to an anti-head-down structure of a cantilevered display bracket. Background Art

[0002] In the field of monitor stands, a mechanical spring cantilever can achieve torque balance, allowing the monitor to hover more stably at a desired position and maintain a balanced state. Therefore, monitor stands equipped with mechanical spring cantilevers have gradually replaced traditional rigid structure monitor stands and are favored by consumers. For example, a dynamically balanced mechanical spring monitor stand cantilever system disclosed in publication number CN114352908A can be used as a reference example.

[0003] After being installed on the mounting plate of the monitor, the monitor will usually be adjusted in pitch angle as required. However, the monitor has a certain weight, so the existing cantilever monitor stand will usually bow to a certain extent, causing certain inconvenience to the user. Utility Model Content

[0017] like Figures 1 to 4As shown, an anti-lowering structure of a cantilever display stand according to an embodiment of the utility model comprises a cantilever 4, a mounting plate 14, and a bolt shaft 9. A rotating head 6 is connected to the upper end of the cantilever 4. A connecting hole 61 is formed on the rotating head 6. A card slot 62 is formed on both sides of the rotating head 6. A rotating head 13 is fixedly connected to the mounting plate 14. A connecting hole 131 is formed on the rotating head 13. The bolt shaft 9 passes through the connecting hole 61 and the connecting hole 131 to realize the configuration. An elastic pad 8 and a stop washer 7 are configured on the outer side of the bolt shaft 9. The clamping portion of the stop washer 7 is clamped on the outer card slot 62. A nut 11 and a stop washer 10 are configured on the inner side of the bolt shaft 9. The nut 11 and the stop washer 10 are An integrated part (the nut 11 and the stop gasket 10 can also be welded to form a whole), the clamping part of the stop gasket 10 is clamped on the inner clamping groove 62; the rotating head 1 6, the rotating head 13, the bolt shaft 9, the elastic gasket 8, the stop gasket 1 7, and the stop gasket 10 are all made of metal; plastic gaskets 12 are arranged on both sides of the rotating head 13; positioning holes 132 are formed on both sides of the rotating head 13, and positioning columns 121 are formed on the plastic gasket 12, and the positioning holes 132 are used to receive the positioning columns 121; a cover 5 is also fixedly connected to the rotating head 13; a connecting frame 3 is provided at the lower end of the cantilever 4, and a base 2 is provided at the lower end of the connecting frame 3, and a clamping assembly 1 is arranged on the base 2 to facilitate quick clamping on a desktop or table top.

[0018] Through the locking action of the bolt shaft, the friction between the plastic gasket and the stop gasket 1 and the stop gasket 2 reaches the desired set value, limiting the relative rotation between the rotating head 2 and the rotating head 1, ensuring the locking effect, and avoiding the monitor lowering condition.

[0019] In order to facilitate the understanding of the present invention, the following description is given in conjunction with the accompanying drawings during specific use;

[0020] The rotating head 6 can rotate on the plane relative to the cantilever 4, and the display is fixed on the mounting plate 14. When the bolt shaft 9 is loosened, the display (mounting plate 14) can swing up and down relative to the rotating head 6 to adjust the pitch angle. After adjustment, tighten the bolt shaft 9, and the large-area contact friction between the plastic gasket 12 and the stop gasket 7 and the stop gasket 2 10 limits the movement of the display (mounting plate 14) to avoid the head-down situation.
