Description

Technical Field

[0001] This utility model relates to the field of planar lifting, and in particular to a linkage lifting desktop mechanism. Background Technology

[0002] Desktop height adjustment is a widely needed function in daily life, allowing users to adjust the height of their desktop.

[0003] Existing height-adjustable desks suffer from poor stability, with objects on the tabletop potentially shifting during the adjustment process. This can easily disrupt work in scenarios requiring high planar stability, such as billiards or precision instrument repair, rendering them impractical.

[0004] Patent document CN215501731U discloses an automatically height-adjustable table that uses a gear to drive a second linkage to swing up and down, thereby raising and lowering the tabletop. However, this solution has some problems in practice. The gear driving the second linkage will cause the meshing gear to bear a very large torque. With long-term use, the tabletop will be under great pressure, which will easily lead to damage to the gear. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a linkage lifting desktop mechanism. The linkage drives the swing arm to swing and realize the lifting of the desktop, which is more stable and has a greater load-bearing capacity.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a linkage lifting desktop mechanism, including a base, a lifting column, a desktop and a lifting component;

[0007] The base is fixed to the lower end of the lifting column, and the lifting column is connected to the desktop support platform through a number of lifting components, with each lifting component distributed around the periphery of the lifting column.

[0008] The lifting assembly includes a swing arm and a connecting rod;

[0009] The lower end of the swing arm is hinged to the main body of the lifting column, and the upper end of the swing arm is hinged to the slider. The lower surface of the table is provided with a slide rail extending from the inside to the outside, and the slider slides in cooperation with the slide rail.

[0010] One end of the connecting rod is hinged to the lifting end of the lifting column, and the other end of the connecting rod is hinged between the two ends of the swing arm.

[0011] When the lifting column rises, one end of the connecting rod moves upward along with the lifting head, which in turn pulls the middle of the swing arm, causing the upper end of the swing arm to swing upward. The swing arm slides along the slide rail via a slider to adapt to its relative position with the tabletop, and the upward movement of the upper end of the swing arm pushes the tabletop up. If it is necessary to lower the tabletop, simply lower the lifting head of the lifting column; the swing arm and connecting rod will move in opposite directions, causing the tabletop to descend.

[0012] Preferably, the lifting column is a pneumatic lifting column, a hydraulic lifting column, or an electric actuator. This solution does not have specific requirements regarding the specific design of the lifting column; any solution that provides lifting functionality is acceptable, making it very flexible in use.

[0013] Preferably, the slide rail adopts a groove structure, and the slider adopts a convex slider that is adapted to slide in the groove. This facilitates a more stable fit between the slider and the groove structure.

[0014] Preferably, the groove is a T-slot, which allows for a more stable fit.

[0015] Preferably, the desktop is rectangular.

[0016] Preferably, the slide rails are arranged along two diagonals of the desktop. This provides more stable support.

[0017] Preferably, the upper end of the rocker arm is provided with side plates on both sides corresponding to the slider, and the side plates and the slider are connected by interlocking pins. This facilitates a stable connection with the slider.

[0018] Preferably, the lifting assembly comprises four sets, which can provide more stable support.

[0019] Preferably, the main body of the lifting column is provided with a support platform facing outward, and the lower end of the swing arm is hinged to the support platform. The support platform provides a fulcrum for the lower end of the swing arm and increases the radius of the circle where the lower end of the swing arm is fixed, thereby increasing the load-bearing capacity of the tabletop support.

[0020] Preferably, a connecting rod is provided on each side of one of the swing arms. This makes the lifting and lowering more stable.

[0021] The beneficial effects of this utility model are:

[0022] This mechanism ensures smooth lifting and lowering when there are objects that need to be placed stably on the table. The joysticks form a mechanism that minimizes displacement during lifting, resulting in smoother and more precise adjustments. The mechanism places the table at its highest point, saving space. A triangular stabilizing structure enhances stability during lifting and lowering, preventing shaking when the lifting is complete. The connecting rod drives the swing arm to achieve the lifting and lowering of the table, making it more stable and capable of supporting higher loads. Attached Figure Description

[0030] To enhance understanding of this utility model, it will be described in further detail below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model.

[0031] Example

[0032] like Figure 1 As shown, a linkage lifting desktop mechanism includes a base 8, a lifting column 9, a desktop 10, and lifting components. The base 8 is fixed to the lower end of the lifting column 9. The lifting column 9 is connected to the support platform 4 of the desktop 10 through several lifting components, each of which is distributed around the periphery of the lifting column 9. Each lifting component includes a swing arm 3 and a connecting rod 6. The lower end of the swing arm 3 is hinged to the main body of the lifting column 9, and the upper end of the swing arm 3 is hinged to a slider 2. A slide rail 1 extending from the inside to the outside is provided on the lower surface of the desktop 10, and the slider 2 is slidably engaged with the slide rail 1. One end of the connecting rod 6 is hinged to the lifting end 5 of the lifting column 9, and the other end of the connecting rod 6 is hinged between the two ends of the swing arm 3.

[0033] When the lifting column 9 rises, one end of the connecting rod 6 moves upward along with the lifting end 5, thereby pulling the middle of the swing arm 3, causing the upper end of the swing arm 3 to swing upward. The swing arm 3 slides on the slide rail 1 via the slider 2 to adapt to its relative position with the tabletop 10. The upper end of the swing arm 3 pushes the tabletop 10 upward. If it is necessary to lower the tabletop 10, simply lower the lifting end 5 of the lifting column 9. The swing arm 3 and the connecting rod 6 move in opposite directions, causing the tabletop 10 to descend.

[0034] The hinge position between the connecting rod 6 and the swing arm 3 will result in a slower lifting speed for the tabletop 10 if it is closer to the upper section of the swing arm 3, and a faster lifting speed if it is closer to the lower section of the swing arm 3.

[0035] The lifting column 9 can be a pneumatic lifting column 9, a hydraulic lifting column 9, or an electric actuator. This solution does not have specific requirements for the specific design of the lifting column 9; any solution that provides lifting functionality is acceptable, making it very flexible. This embodiment uses an electric actuator.

[0036] The slide rail 1 adopts a groove structure, and the slider 2 adopts a convex slider 2 that is adapted to slide in the groove. This facilitates a more stable fit between the slider 2 and the groove structure.

[0037] The slide rail adopts a T-shaped groove, which allows for a more stable fit. The desktop 10 is rectangular. The slide rail 1 is arranged along the two diagonals of the desktop 10, providing more stable support.

[0038] The upper end of the rocker arm 3 is provided with side plates corresponding to both sides of the slider 2, and the side plates and the slider 2 are connected by interlocking pins. This facilitates a stable connection with the slider 2.

[0039] The lifting assembly comprises four sets, providing more stable support.

[0040] The main body of the lifting column 9 is provided with a support platform 4, and the lower end of the swing arm 3 is hinged to the support platform 4. The support platform 4 provides a fulcrum for the lower end of the swing arm 3 and increases the radius of the circle where the lower end of the swing arm 3 is fixed, thereby increasing the load-bearing capacity of the tabletop 10.

[0041] A connecting rod 6 is provided on each side of the swing arm 3. This makes the lifting and lowering more stable.

[0042] The beneficial effects of this utility model are:

[0043] The mechanism ensures smooth lifting and lowering when there are objects that need to be placed stably on the tabletop 10. The joysticks form a displacement-reducing mechanism, minimizing movement during lifting and lowering for smoother and more precise adjustments. This mechanism positions the tabletop 10 at its highest point, saving space. The triangular stabilizing structure enhances stability during lifting and lowering, preventing shaking when the lifting and lowering process is complete and the tabletop is fixed in place.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
