[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0035] Currently, some coffee tables on the market have height-adjustable functions to raise and lower the top panel 100. In order to improve the convenience of use, current coffee tables use a single lifting column 200 to support the top panel 100. Although the height-adjustable function can be achieved, it is easy to cause wobbling. Therefore, this utility model proposes a height-adjustable anti-wobbling coffee table device, in which the lifting column 200 is fixed in two concentric circles in the vertical direction, and there is a certain height difference between the two points. This allows the lifting column 200 to move in a concentric circle with the center of the fixed reference circle at the lower end of the lifting column 200 during the raising and lowering process, thereby reducing the amplitude of wobbling.
[0036] like Figure 1 and Figure 2 As shown, a lifting and anti-shaking coffee table device according to an embodiment of the present invention includes a coffee table top plate 100, a lifting column 200, and a coffee table base frame 300.
[0037] The lifting column 200 is vertically installed between the top plate 100 and the base frame 300 of the coffee table. The lifting column 200 is a telescopic rod structure, and the lifting action of the telescopic rod structure can be achieved by electric, pneumatic or manual means.
[0038] In this embodiment, the upper end of the lifting column 200 is fixedly connected to the coffee table top plate 100. The coffee table top plate 100 in this embodiment is flat and horizontally arranged. The coffee table top plate 100 is used to place teacups and tea-making utensils, wine glasses, fruits, fruit knives, ashtrays, flowers, etc. In some other embodiments, the coffee table top plate 100 may adopt other shapes and structures. In order to improve the stability of the support, the upper end of the lifting column 200 is connected to the center position of the coffee table top plate 100.
[0039] The lower end of the lifting column 200 is connected to the coffee table base 300, specifically: as follows: Figure 1 and Figure 3 As shown, the coffee table base 300 in this embodiment is provided with a fixed connection structure 310 and a vertical guide structure 320. The fixed connection structure 310 is fixedly connected to the lower end of the lifting column 200, while the vertical guide structure 320 is located between the upper and lower ends of the lifting column 200. It can be understood that the vertical guide structure 320 is located above the fixed connection structure 310, and a set height difference is formed between the vertical guide structure 320 and the fixed connection structure 310. The vertical guide structure 320 slides against the outer peripheral wall of the lifting column 200.
[0040] In this embodiment, the lower end of the lifting column 200 is fixed by the fixed connection structure 310, while the vertical guide structure 320 limits the outer periphery of the lifting column 200, so that the coffee table base 300 forms two limiting points for the lifting column 200. One is a fixed limiting point at the lower end of the lifting column 200, and the other is a radial limiting point located above the lower end of the lifting column 200. The vertical guide structure 320 is used to limit the radial direction of the lifting column 200 to prevent the lifting column 200 from tilting outward and to avoid interfering with the lifting function of the lifting column 200.
[0041] In use, the height of the coffee table top plate 100 is adjusted by extending and retracting the lifting column 200. For the support and positioning of the lifting column 200, this utility model uses a fixed connection structure 310 to support and fix the lower end of the lifting column 200. At the same time, a vertical guide structure 320 guides the outer peripheral wall of the lifting column 200. The guiding position of the vertical guide structure 320 on the outer peripheral wall of the lifting column 200 is located between the upper and lower ends of the lifting column 200, so that the lifting column 200 is fixed concentrically at two points in the vertical direction, and there is a certain height difference between the two points. This ensures that the column maintains vertical movement during the lifting process, reduces the sway amplitude, and thus prevents shaking.
[0042] like Figure 3 As shown, the coffee table base 300 of this embodiment is a shell structure. The top of the shell structure is provided with a through hole 330, which is arranged vertically. The diameter of the through hole 330 is larger than the outer diameter of the lifting column 200. The fixed connection structure 310 is provided at the bottom of the shell structure. The lower end of the lifting column 200 passes through the through hole 330 and connects with the fixed connection structure 310. The vertical guide structure 320 is provided in the through hole 330 to guide and limit the lifting column 200 in the vertical direction. In this way, the lower part of the lifting column 200 can be hidden and installed, making the coffee table more beautiful.
[0043] In some other embodiments, the coffee table base 300 may be a frame structure.
[0044] like Figure 3 , 4 As shown in Figure 5, the vertical guide structure 320 of this embodiment includes a guide ring 321. The guide ring 321 is fixed to the top of the coffee table base 300, and the guide ring 321 is coaxially arranged with the through hole 330. The guide ring 321 is sleeved on the outer periphery of the lifting column 200, so that the lifting column 200 can be limited and guided by the guide ring 321.
[0045] To improve the smoothness of the extension and retraction of the lifting column 200, the vertical guide structure 320 of this embodiment also includes a plurality of rolling guide parts 322, wherein the plurality of rolling guide parts 322 are arranged in a ring at intervals on the guide ring sleeve 321, and the plurality of rolling guide parts 322 roll in contact with the outer peripheral wall of the lifting column 200. In this embodiment, the plurality of rolling guide parts 322 support and limit the outer peripheral wall of the lifting column 200, thereby fixing the center point of the lifting column 200 and reducing friction.
[0046] In this embodiment, the guide ring sleeve 321 includes a guide cylinder 3211 and a connecting ring 3212. The connecting ring 3212 is connected to the lower end of the guide cylinder 3211 and extends radially around the guide cylinder 3211. The connecting ring 3212 is connected to the top of the coffee table base 300. In this embodiment, the connecting ring 3212 has a plurality of connecting holes 3213 evenly distributed in a ring. During installation, self-tapping screws are passed through the connecting holes 3213 and connected to the top of the coffee table base 300 to achieve fixed installation of the guide ring sleeve 321. A plurality of rolling guide parts 322 are installed on the guide cylinder 3211.
[0047] The rolling guide part 322 of this utility model embodiment includes a bullseye wheel 3221, which provides rolling support and limit for the outer peripheral wall of the lifting column 200. The bullseye wheel 3221 includes a mounting base 3222 and a ball bearing 3223. The ball bearing 3223 is rotatably mounted on the mounting base 3222. During installation, the ball bearing 3223 abuts against the outer peripheral wall of the lifting column 200.
[0048] Furthermore, the rolling guide portion 322 in this embodiment also includes a connecting rod 3224 and a nut 3225. The guide cylinder 3211 has a plurality of mounting holes 3214 that extend radially and are evenly distributed in an annular shape. The guide cylinder 3211 has a wall thickness of 3mm and is used to install the bullseye wheel 3221. The connecting rod 3224 extends radially. The inner end of the connecting rod 3224 is fixedly connected to the mounting base 3222, and the outer end of the connecting rod 3224 passes radially through the mounting hole 3214 and is threadedly connected to the nut 3225. During installation, the nut 3225 is used to lock the bullseye wheel 3221 to fix it to the inner circumference of the guide cylinder 3211.
[0049] like Figure 4 As shown, the mounting hole 3214 in this embodiment is a screw hole structure, and the connecting rod 3224 is threadedly connected to the mounting hole 3214 to further improve the firmness of the bullseye wheel 3221 installation.
[0050] To avoid loosening the bullseye wheel 3221, such as Figure 4 and Figure 5 As shown, the rolling guide part 322 in this embodiment also includes a spring washer 3226. The spring washer 3226 is sleeved on the outer periphery of the connecting rod 3224 and is located between the nut 3225 and the outer peripheral wall of the guide ring sleeve 321. The spring washer 3226 is used to press the guide cylinder 3211 to prevent the bullseye wheel 3221 from rotating and loosening when vibrating.
[0051] The ball bearing 3223 of the bullseye wheel 3221 is tangent to the lifting column 200. By adjusting the depth of the thread, the bullseye wheel 3221 can be pressed tightly against the lifting column 200. When the lifting column 200 rises and falls, it will vibrate with the bullseye wheel 3221. Due to the effect of the spring washer 3226, even if there is vibration, it is not easy to loosen, which ensures smooth operation.
[0052] like Figure 1 and Figure 3 As shown, the fixed connection structure 310 of this embodiment includes a first connecting plate 311 and a plurality of first connecting bolts 312. The plurality of first connecting bolts 312 pass through the first connecting plate 311 and the bottom of the coffee table base 300 in sequence from bottom to top and are connected to the bottom of the lifting column 200. The first connecting plate 311 can increase the supporting area range to improve the stability of fixing the lower end of the lifting column 200.
[0053] At the same time, such as Figure 1 and Figure 3 As shown, the upper end of the lifting column 200 is connected to a second connecting plate 210, and the second connecting plate 210 is connected to the bottom surface of the coffee table top plate 100. In this embodiment, the second connecting plate 210 is connected to the coffee table top plate 100 by a plurality of second connecting bolts 211.
[0054] The bottom of the coffee table base 300 in this embodiment is provided with a pulley assembly 340 to facilitate the movement of the coffee table.
