Description

Technical Field

[0001] The present invention relates to the technical field of lift tables, in particular to a lift table with a lubrication and maintenance mechanism. Background Art

[0002] Human evolution progressed from quadrupedal to upright walking. Researchers studying the history of furniture development worldwide have discovered that after humans began walking upright, they discovered that sitting helped reduce fatigue during daily activities, leading to the invention of seating. This seated working style has been passed down through generations, but as people spent more and more time sitting at their desks, they gradually realized that prolonged sitting was detrimental to work efficiency. This led to the introduction of sit-stand desks, which became a popular and healthy way to work.

[0003] Currently, the most common lifting method for existing lift tables is to raise and lower the tabletop via the lifting frames at both ends. To ensure smoother lifting, manual lubrication is usually applied to the lifting points during design. Manual lift tables on the market usually have mechanisms such as slide rails when lifting. Due to the small dripping surface, the lift table needs to be slid up and down on both sides to evenly spread the oil on the slide rails, making the operation more cumbersome and laborious.

Implementation Method

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0028] like Figure 1 and Figure 2 When the lifting table is lifted up, the lifting lever 2 is tightened and the cam 3 is tightened, so that the lifting lever 2 can be tightened and the cam 3 is tightened.

[0029] Among them, such as Figure 2As shown, in order to trigger oil dripping when the locking mechanism 5 is controlled to adjust its height, thereby facilitating automatic lubrication of structures such as the slide rail 4, the oil dripping assembly 6 includes an oil storage cylinder 7, a fixing frame 8, an oil guiding mechanism 9 and an oil outlet mechanism 10. The oil storage cylinder 7 is fixedly connected to the outer wall of the fixed sleeve rod 3 through the fixing frame 8, the oil outlet mechanism 10 is arranged inside the oil storage cylinder 7, and the oil guiding mechanism 9 is installed at the bottom of the oil storage cylinder 7 and is used to evenly drip lubricating oil to the inner side of the fixed sleeve rod 3.

[0030] At the same time, if Figure 3 As shown, in order to allow the lubricating oil inside the oil storage barrel 7 to flow freely and be automatically sealed, the oil guide mechanism 9 includes a movable plate 11, a closing block 12, a fixed plate 13 and a moving rod 14. The movable plate 11 is in sliding contact with the wall of the oil storage barrel 7, the closing block 12 is fixedly connected to the bottom of the movable plate 11 through a connecting rod, the fixed plate 13 is fixed to the inner wall of the oil storage barrel 7, an oil outlet hole 15 is provided on the fixed plate 13, the closing block 12 is slidably connected to the hole wall of the oil outlet hole 15, the top end of the moving rod 14 is fixed to the top of the closing block 12, and the bottom end of the moving rod 14 passes through the bottom of the oil storage barrel 7 and extends vertically downward and is fixedly connected to the output end of the locking mechanism 5.

[0031] In addition, if Figure 4 and Figure 8 As shown, in order to facilitate the uniform dripping of the lubricating oil introduced from the bottom of the oil storage cylinder 7 to the position above the slide rail 4, the oil outlet mechanism 10 includes an oil outlet pipe 16 and an oil dripping pipe 17. The top end of the oil outlet pipe 16 is connected to the interior of the oil storage cylinder 7, and the bottom end of the oil outlet pipe 16 passes through the outer wall of the fixed sleeve rod 3 and extends to just above the slide rail 4. Two oil dripping pipes 17 are provided, and the two oil dripping pipes 17 are connected to the interior of the oil outlet pipe 16.

[0032] At the same time, if Figure 6 and Figure 7 As shown, in order to fix the position of the lifting rod 2 and generate a linkage to trigger the oil dripping assembly 6 to work, the locking mechanism 5 includes a locking screw 18, a rotating screw sleeve 19 and a transmission assembly 20. The locking screw 18 is threadedly connected to the rotating screw sleeve 19, and the rotating screw sleeve 19 is rotatably connected to the outer wall of the fixed sleeve 3 through a bearing. The outer wall of the lifting rod 2 is evenly spaced with a plurality of locking holes 21 that are compatible with the locking screw 18. One end of the locking screw 18 is fixed to the end away from the locking hole 21, and the bottom end of the limiting plate 22 is fixed to the limiting rod 23. The limiting rod 23 is slidably connected to the outer wall of the fixed sleeve 3, and the transmission assembly 20 is installed on the outside of the fixed sleeve 3, and the output end of the transmission assembly 20 is transmission-connected to the moving rod 14.

[0033] In addition, if Figure 3 As shown, in order to facilitate the flow of lubricating oil on the upper portion of the movable plate 11 , a plurality of through holes 35 are evenly formed on the movable plate 11 .

[0034] At the same time, if Figure 5 As shown, in order to facilitate the addition of lubricating oil, an injection cap 34 is provided on the top of the oil storage barrel 7 , and the injection cap 34 is threadedly connected to the top of the oil storage barrel 7 .

[0035] When maintaining the slide rail 4 of the lifting rod 2: first, the personnel works by rotating the transmission assembly 20 before adjusting the height. The transmission assembly 20 transmits the torque of the hand to the rotating screw sleeve 19 on the one hand, so that the rotating screw sleeve 19 rotates, and the rotating screw sleeve 19 drives the locking screw 18 to move out of the locking hole 21. At this time, the lifting rod 2 releases the locking effect. On the other hand, the torque of the hand is transmitted to the lower end of the moving rod 14 through the transmission assembly 20, so that the lower end of the moving rod 14 moves upward, and the moving rod 14 drives the closing block 12 to move, so that the oil outlet 15 is opened, allowing the lubricating oil on the upper part of the movable plate 11 to flow into the uppermost The oil will flow down from the bottom of the oil outlet pipe 16 and out from the oil drip pipe 17, wherein the oil outlet pipe 16 will drip the lubricating oil to the inner bottom position of the slide rail 4, and the oil drip pipe 17 will drip the lubricating oil onto the inner wall of the slide rail 4, so that the oil can be automatically dripped to multiple positions on the inner side of the slide rail 4, and the lubricating oil flows downward under the action of its own gravity, thereby flowing to multiple positions on the inner side of the slide rail 4. At this time, operate the lifting rod 2 to adjust the height, and the slider will slide at the position where the oil has dripped, so as to apply the lubricating oil. After adjusting to the specified height, reset the locking mechanism 5 to lock the lifting rod 2.

[0036] In addition, when the lifting table is lowered, the slider will continue to slide on the slide rail 4 that has been lubricated last time. At the same time, oil will continue to drip from the oil outlet pipe 16 and the oil drip pipe 17 to ensure that there is enough oil when the lifting table is raised next time. In summary, this solution is achieved by linking an oil dripping component 6 to the existing locking mechanism 5. As long as the personnel adjust the height, they can trigger the oil dripping component 6 to work by opening the locking mechanism 5 to drip oil. When dripping oil, the oil can continue to drip onto the inner wall of the slide rail 4, thereby increasing the oil dripping surface. The oil dripping process can also continue when the lifting table slides up and down on both sides, making the lubrication operation more time-saving and labor-saving, and further improving the lubrication and maintenance efficiency of the lifting table.

The limit rod 23 is slidably connected to the outer wall of the fixed sleeve 3. The transmission assembly 20 is installed on the outside of the fixed sleeve 3, and the output end of the transmission assembly 20 is transmission-connected to the moving rod 14. Through the locking mechanism 5, the position of the lifting rod 2 can be fixed and the linkage triggering oil drip assembly 6 can be generated to work.

[0038] Among them, such as Figure 9 As shown, in order to facilitate the generation of linkage action, the transmission assembly 20 includes a transmission rod 24, a driving gear 25, a transmission gear 26, an active bevel gear 27, a passive bevel gear 28 and a screw rod 29.

An L-shaped rod 32 is fixed to one side of the moving block 31, and the L-shaped rod 32 is fixed to the bottom end of the moving rod 14.

[0039] In addition, if Figure 9 As shown, in order to facilitate manual adjustment, a handle 33 is fixed to the top end of the transmission rod 24, and anti-slip grooves are provided on the outer side of the handle 33.

[0040] During adjustment: by manually rotating the handle 33, the handle 33 drives the transmission rod 24 to rotate, and the transmission rod 24 drives the rotating screw sleeve 19 to rotate through the engagement of the active bevel gear 27 and the passive bevel gear 28, and the rotating screw sleeve 19 will drive the locking screw 18 to move outward, and move one end of the locking screw 18 out of the locking hole 21, thereby releasing the locking effect of the lifting rod 2. At the same time, the transmission rod 24 will also drive the driving gear 25 to rotate, and the driving gear 25 drives the transmission gears 26 on both sides to rotate, and the transmission gear 26 drives the screw rod 29 to rotate, and the screw rod 29 drives the rotating block 30 to move upward, so that the rotating block 30 drives the moving rod 14 to move upward through the L-shaped rod 32, thereby starting the oil drip assembly 6.
