Description

Technical Field

[0001] This utility model relates to a multi-link lifting metal table, belonging to the technical field of lifting table technology. Background Technology

[0002] Height-adjustable desks, as a type of office furniture, are widely used in modern office environments. Their core function is to adjust the height of the desktop through a lifting mechanism to meet the needs of users working in sitting or standing positions.

[0003] Chinese Patent (Publication No.: CN 215014448 U) discloses a height-adjustable metal table, comprising an I-shaped metal table body, a base plate, a tabletop above the base plate, and a table leg supporting the tabletop. The base plate has multiple foot pads for stable placement. A connecting seat is detachably mounted on the bottom of the tabletop. The table leg includes a protective sleeve detachably mounted on the top of the base plate and a height-adjusting pressure bar for adjusting the tabletop height. The lower end of the pressure bar is inserted and fixed into a mounting cavity, and the upper end is connected to the connecting seat. This invention provides a simple and reasonable metal table structure. With only one table leg, the tabletop height can be arbitrarily adjusted using a single height-adjusting pressure bar. Operation is simple and convenient, meeting the needs of users of different body types and effectively improving the user experience. Furthermore, all components of the metal table are detachable, making it easy to disassemble, transport, and store, suitable for widespread application. However, single-bar height-adjustable desks have the following technical drawbacks: First, they lack stability. When the desktop is subjected to eccentric loads (such as when a user presses down on one side of the desktop with one hand), the single-bar support structure is prone to tilting or wobbling, which may even cause the desktop to flip over in severe cases. Second, they have limited load-bearing capacity. The force-bearing area of ​​a single telescopic bar is small, and it is prone to deformation or jamming when subjected to large loads for a long time. Finally, they have poor synchronization of lifting. The single-bar drive makes it difficult to ensure the height consistency of the four corners of the desktop, which may cause the desktop to tilt after long-term use.

[0004] Therefore, a multi-link lifting metal table is proposed. Summary of the Invention

[0005] In view of this, the present invention provides a multi-link lifting metal table to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example 1

[0022] like Figure 1-4 As shown, this utility model embodiment provides a multi-link lifting metal table, including: The lifting mechanism 100 includes a lifting plate 101. Fixing blocks 102 are fixedly connected to the four sides of the bottom of the lifting plate 101. A swing plate 103 is movably connected to the inner side of each fixing block 102 via a rotating shaft. A threaded sleeve 104 is movably connected to the inner side of each swing plate 103 via a rotating shaft. A bidirectional threaded rod 105 is threadedly connected to the inner side of the threaded sleeve 104. Fixing plates 106 are provided on both the left and right sides of the bidirectional threaded rod 105. A servo motor 107 is fixedly connected to the right side of the right fixing plate 106, and the output end of the servo motor 107 is fixedly connected to the right side of the fixing plate 106.

[0023] By setting up a lifting mechanism 100, the output end of the servo motor 107 drives the bidirectional threaded rod 105 to rotate. The bidirectional threaded rod 105 drives the threaded sleeve 104 to move inward or outward simultaneously through the action of the thread. During the movement, the threaded sleeve 104 drives the swing plate 103 to swing. During the swing, the swing plate 103 drives the lifting plate 101 to move up and down through the fixed block 102, thereby completing the lifting work of the lifting plate 101. The overall structure is more stable, the multi-rod support is less prone to tilting or shaking, and the load-bearing capacity is also enhanced. Example 2

[0024] like Figure 5As shown, in one embodiment, a heating assembly 200 is also included. The heating assembly 200 includes a heating plate 201, which is fixedly connected to the inner cavity of the lifting plate 101. The heating assembly 200 also includes a knob 202, which is fixedly connected to the front side of the top right side of the lifting plate 101 and electrically connected to the heating plate 201. The heating assembly 200 also includes a temperature display 203, which is fixedly connected to the lower part of the top right side of the lifting plate 101 and located to the left of the knob 202. The temperature display 203 is electrically connected to the heating plate 201.

[0025] By setting up the heating component 200, the heating plate 201 can heat the lifting plate 101. The knob 202 can control the temperature adjustment of the heating plate 201, and the temperature display 203 can display the temperature for easy reference. It can also provide heating in cold seasons, improving the comfort of use. Example 3

[0026] like Figure 2-4 and Figure 6 As shown, in one embodiment, the lifting mechanism 100 further includes a controller 108, which is fixedly connected to the back side of the top right side of the lifting plate 101, and is electrically connected to the servo motor 107. A connecting plate 109 is fixedly connected to the bottom of the fixed plate 106, and a connecting strip 110 is fixedly connected to the inner side of the connecting plate 109. Slide grooves 111 are provided on both the left and right sides of the top of the connecting strip 110. A slider 112 is fixedly connected to the bottom of the threaded sleeve 104, and the slider 112 is slidably connected to the inner side of the slide groove 111. A sleeve 113 is fixedly connected to all four sides of the connecting plate 109. A lifting rod 114 is slidably connected to the inner side of the sleeve 113, and the top of the lifting rod 114 is fixedly connected to the bottom of the lifting plate 101. A pressure spring 115 is provided in the inner cavity of the sleeve 113, and the top of the pressure spring 115 is fixedly connected to the bottom of the lifting rod 114.

[0027] By setting the controller 108, the servo motor 107 can be easily controlled to adjust the height of the lifting plate 101. By setting the connecting plate 109, connecting bar 110, slide groove 111 and slider 112, the stability of the threaded sleeve 104 during movement can be improved. By setting the sleeve 113 and lifting rod 114, the stability of the lifting plate 101 during lifting can be improved. By setting the bidirectional threaded rod 105, the lifting plate 101 can be buffered during lifting.

[0028] In operation, this invention works as follows: First, when the height of the lifting plate 101 needs to be adjusted, the output end of the servo motor 107 drives the bidirectional threaded rod 105 to rotate. The bidirectional threaded rod 105 drives the threaded sleeve 104 to move inward or outward simultaneously through the thread. During the movement, the threaded sleeve 104 drives the swing plate 103 to swing. During the swing, the swing plate 103 drives the lifting plate 101 to move up and down through the fixed block 102, thereby completing the lifting and lowering of the lifting plate 101. When the lifting plate 101 is raised and lowered, it drives the lifting rod 114 to rise and fall. The lifting rod 114 compresses the pressure spring 115, making the lifting and lowering of the lifting plate 101 more stable. During use, the heating plate 201 can also heat the lifting plate 101. The knob 202 can control the temperature adjustment of the heating plate 201, and the temperature display 203 can display the temperature for easy monitoring. In cold seasons, it also provides heating, improving the comfort of use.
