Description

Technical Field

[0001] This application relates to the field of electric height-adjustable desks, and in particular to a single-column table leg folding mechanism and an electric height-adjustable desk having the single-column table leg folding mechanism. Background Technology

[0002] To simplify their structure, some existing electric height-adjustable desks use a single-column leg structure.

[0003] Traditional single-column table leg structures use fasteners to fix the legs to the drive mechanism, thereby supporting the drive mechanism; however, this type of structure fixes the legs to the drive mechanism in place, making it inconvenient to fold and disassemble, and failing to achieve convenient storage. Utility Model Content

[0004] The purpose of this application is to provide a single-column table leg folding mechanism that is simple in structure, easy to adjust, and easy to package and transport, as well as an electric lifting table with the single-column table leg folding mechanism.

[0005] To achieve the above objectives, this utility model provides a single-column table leg folding mechanism, including a leg and a driving component. The driving component is connected to the leg through a folding assembly, and the folding assembly enables folding between the driving component and the leg or vertical fixation between the driving component and the leg.

[0006] The folding assembly includes an angle adjuster, a wrench, a camshaft, a cam, and a limiting component. The angle adjuster is fixed to the foot plate and has a hollow structure with open top and sides. The bottom end of the drive component is vertically inserted into the angle adjuster, and the drive component is locked to the angle adjuster by the limiting component. The drive component can rotate around the angle adjuster and tilt towards the foot plate. The camshaft is rotatably connected to one side of the angle adjuster. One end of the camshaft extends outward from the angle adjuster and is fixed with the wrench. The other end of the camshaft extends inward from the angle adjuster and is inserted into the drive component, and is fixed with the cam. The wrench can drive the camshaft to rotate, locking or unlocking the cam and the drive component.

[0007] Preferably, the foot plate has an I-shaped structure, including a set of parallel horizontal plates and a vertical plate fixed between the two horizontal plates.

[0008] To minimize the overall volume after folding, the angle adjuster is detachably fixed to one end of the longitudinal plate.

[0009] To prevent the single-column table leg folding mechanism from slipping, several anti-slip plates are fixed to the bottom of the horizontal plate.

[0010] To facilitate the disassembly, assembly, and fastening of the drive component and the angle adjuster, several insertion holes are provided on both sides of the angle adjuster for the limiting component to pass through. Several locking holes corresponding to the insertion holes are provided on both sides of the bottom end of the drive component. The limiting component passes through the insertion holes and locking holes in sequence and is locked to the drive component.

[0011] To facilitate the installation and axial rotation of the camshaft, and to serve a positioning function, a bushing is provided on one side of the angle adjuster. The camshaft passes through the bushing and is rotatably connected to the angle adjuster through the bushing.

[0012] This utility model also provides an electric height-adjustable table, which has the above-mentioned single-column table leg folding mechanism.

[0013] In summary, this utility model has the following beneficial effects: the foot plate and drive component are designed as foldable and retractable structures, which facilitates simple packaging and makes packing and unpacking more convenient. The product is no longer assembled in separate parts, making it more convenient for customers to unpack and install, and also more convenient to store. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of the embodiments of this utility model, unless otherwise expressly specified and limited, the terms "installed," "connected," "linked," "set up," "equipped with," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Example 1:

[0022] like Figure 1 , Figure 2 The single-column table leg folding mechanism shown includes a leg and a driving component 4. The driving component 4 is connected to the leg through a folding assembly. The folding assembly can realize the folding between the driving component 4 and the leg or realize the vertical fixation between the driving component and the leg.

[0023] Specifically, the foot plate is an I-shaped structure, including a set of parallel horizontal plates 1 and a vertical plate 2 fixed between the two horizontal plates 1. The horizontal plates 1 and the vertical plate 2 can be fixed by welding or screws. The bottom end of the horizontal plate 1 can be detachably installed with an anti-slip plate 7.

[0024] Specifically, the driving component 4 is a hollow square tube;

[0025] Specifically, the folding assembly includes an angle adjuster 3, a wrench 5, a camshaft 12, a cam 8, and a limiting member 6. The angle adjuster 3 is fixed to one end of the longitudinal plate 2 of the foot plate. The angle adjuster 3 has a hollow frame structure with open top and sides. The bottom end of the drive member 4 is vertically inserted into the angle adjuster 3, and the drive member 4 is locked to the angle adjuster 3 by several limiting members 6. Several insertion holes for the limiting members 6 to pass through are opened on both sides of the angle adjuster 3. At the same time, several locking holes 10 corresponding to the insertion holes are opened on both sides of the bottom end of the drive member 4. The limiting members 6 pass through the insertion holes in sequence. The locking hole 10 is locked with the driving component 4. The driving component 4 can rotate around the angle adjuster 3 and tilt towards the foot plate. A bushing 9 is fixed on one side of the angle adjuster 3. The camshaft 12 passes through the bushing 9 and is rotatably connected to the angle adjuster 3 through the bushing. One end of the camshaft 12 extends outward from the angle adjuster 3 and is fixed with the wrench 5. The other end of the camshaft 12 extends inward from the angle adjuster 3 and is inserted into the through hole 11 on one side of the driving component 4, and is fixed with the cam 8. The cam 8 is eccentric relative to the through hole 11. The wrench 5 can drive the camshaft 12 to rotate, so that the cam 8 is locked or unlocked from the driving component 4.

[0026] In use, the drive unit 4 is vertically inserted into the angle adjuster 3, and then the camshaft 12 and cam 8 are inserted into the drive unit 4. The camshaft 12 is rotated by the wrench 5 to lock the cam 8 with the drive unit 4. Then, the drive unit 4 and the angle adjuster 3 are connected by several limiting pieces 6, and it can be used normally. When it is necessary to fold the drive unit 4, first the camshaft 12 is rotated by the wrench 5 to unlock the cam 8 from the drive unit 4. Then, the limiting pieces 6 are removed, and the angle adjuster 3 can be flipped downwards to abut against the longitudinal plate 2, so that the drive unit 4 and the foot plate can be folded.

[0027] Example 2:

[0028] Combination Figure 3 , Figure 4 As shown, this utility model also provides an electric lifting table, which is equipped with the above-mentioned single-column table leg folding mechanism. The top of the driving component 4 is fixed to the table board 13 through the support 15 and the support plate 14. The driving component 4 can drive the table board 13 to achieve lifting.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, principle and application direction of this application should be covered within the scope of protection of this application.
