Description

Technical Field

[0001] The utility model relates to the technical field of display bases, in particular to a telescopic mechanism of a display base. Background Art

[0002] A display base is a device used to support a display screen. The display base not only bears the weight of the display screen, but also often affects the user experience and the space utilization efficiency. Through the display base, the position of the display, such as the angle and height, can be adjusted.

[0003] The existing display bases usually use multiple sets of sleeves sleeved together to form a support tube. When the height of the display screen needs to be adjusted, by moving the multiple sets of sleeves separately, and only after a single sleeve is moved can the other sleeves be moved in sequence, which makes the adjustment of the display base relatively slow and inconvenient to use. Therefore, a telescopic mechanism for accelerating the height adjustment of the display base is needed to adjust the height of the display base. Summary of the Utility Model

[0038] The outer surface of the lead screw 22 is provided with a reverse thread structure, and the connecting rod 25 is staggered into an X-shaped structure;

[0039] When the lead screw 22 rotates, the lead screw 22 converts the rotational motion into a linear motion, driving the slider 23 to move towards each other or in opposite directions;

[0040] The outer end of the fixed column 26 is fixedly connected to the lower end inside the support tube 12, and the driven rod 27 and the support rod 24 are in a vertically collinear state;

[0041] When the connecting rod 25 rotates along the fixed column 26, since the bottom end of the connecting rod 25 moves horizontally towards each other, the top end of the connecting rod 25 moves vertically upward;

[0042] Working principle: When it is necessary to extend and retract the support tube 12, start the reciprocating motor 21. The reciprocating motor 21 drives the lead screw 22 to rotate. The lead screw 22 drives the slider 23 to move towards each other. The slider 23 moving towards each other drives the support rod 24 to move horizontally inward. The support rod 24 moving inward drives the connecting rod 25 to rotate inward along the fixed column 26, and the connecting rod 25 maintains synchronous rotation through the driven rod 27. At the same time, the fixed column 26 moves vertically upward under the drive of the connecting rod 25, so that the fixed column 26 drives the support tube 12 to move vertically upward, enabling the support tube 12 to maintain synchronization during extension and retraction.

[0043] Please refer to Figure 3As shown, this embodiment, based on the above embodiment, further includes:

[0044] A support assembly, which includes a fixed block 31, a fixed shaft 32, a support plate 33, a support bottom plate 34, and a card slot 35;

[0046] The fixed block 31 is used to support the fixed shaft 32. The fixed shaft 32 is used to drive the support plate 33 to move. The support plate 33 is used to support the fixed shaft 32. The support bottom plate 34 is used to support the support plate 33. The card slot 35 is used to limit the support plate 33;

[0047] The card slot 35 is opened relative to the bottom end of the card slot 35, and the support bottom plate 34 is located on both sides of the support tube 12;

[0048] When the support tube 12 moves upward, the support plate 33 moves upward under the drive of the fixed block 31 and the fixed shaft 32 and rotates along the fixed shaft 32 under the action of gravity;

[0049] Working principle: When the support tube 12 is telescoped, the support tube 12 moves upward to drive the fixed block 31 to move upward. The fixed block 31 drives the support plate 33 to move upward through the fixed shaft 32. The support plate 33 moves upward and rotates along the fixed shaft 32 under the action of gravity, and makes the bottom end of the support plate 33 contact the inside of the support bottom plate 34.
