[0034] In the description of the present utility model, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0035] Refer to Figures 1 to 4, the lifting table of the embodiment of the present utility model includes a tabletop (not shown in the figure), a table frame (not shown in the figure), and a wire hiding tube. The tabletop is fixed to the upper end of the table frame, the table frame can be lifted up and down, one end of the wire hiding tube is fixedly connected to the bottom surface of the tabletop, and the other end is fixedly connected to the bottom of the table frame. Among them, the wire hiding tube includes a support arm 100, a middle rotating member 200, and an end rotating member 300. There are multiple support arms 100. Along the length direction of the support arm 100, a wire hiding channel 110 is provided inside the support arm 100; both ends of the middle rotating member 200 are respectively rotatably connected to a support arm 100, so that multiple support arms 100 can be folded or extended. The middle rotating member 200 is provided with a middle connection cavity 210, and the middle connection cavity 210 communicates with the wire hiding channels 110 at both ends. The middle rotating member 200 is made of an elastic material; there are two end rotating members 300. One end of one end rotating member 300 is rotatably connected to the upper end of the uppermost support arm 100, and the other end is fixedly connected to the bottom surface of the tabletop; one end of the other end connecting member is rotatably connected to the lower end of the lowermost support arm 100, and the other end is fixedly connected to the bottom of the table frame; the end rotating member 300 is provided with an end connection cavity 310, and the end connection cavity 310 communicates with the wire hiding channel 110.

[0036] In actual use, as the tabletop rises or falls, multiple rotatably connected support arms 100 can extend or fold to match the height of the tabletop. The wires of electrical appliances such as computers placed on the tabletop can be put into the end connection cavity 310 of the upper end rotating member 300, and extend into the wire hiding channel 110 of the support arm 100 for wire hiding and fixing, and finally extend out from the end connection cavity 310 of the lower end connecting member. Among them, when passing through the middle rotating member 200, the wire can pass through the middle connection cavity 210 of the middle rotating member 200, so that the wire can be completely hidden inside the entire wire hiding tube.

[0037] Specifically, when the table frame is shaken during use, resulting in a position stagger between the bottom of the table frame and the tabletop, adjacent two support arms 100 will also be misaligned. At this time, the elastic middle rotating member 200 between the two support arms 100 can generate deformation. Specifically, the deformation of the middle rotating member 200 between the two support arms 100 is used to provide the deformation margin of the entire wire hiding tube, ensuring that the entire wire hiding tube will not undergo irreversible deformation and improving the service life of the wire hiding tube.

[0038] In summary, the specific implementation of the present utility model has the following advantages:

[0039] 1. By using multiple foldable or extendable support arms 100 to cooperate with the liftable tabletop, the wires of the items placed on the tabletop can be hidden inside the wire hiding channel 110;

[0040] 2. Use the elastic middle rotating member 200 as the connecting member between two adjacent support arms 100, so that there is a misalignment margin between two adjacent support arms 100 during the shaking of the table frame, avoiding damage to the middle rotating member 200 and resulting in the inability of the entire wire hiding tube to be folded or extended normally.

[0041] Referring to Figure 1 , as a specific embodiment of the present utility model, there are two support arms 100, and the two support arms 100 are rotatable to fold the two support arms 100 or form an angle. Preferably, when the two support arms 100 are stacked and form a folded shape, the volume of the entire wire hiding tube can be minimized, which is convenient for transportation. When the wire hiding tube is actually used, the height change between the tabletop and the bottom of the table frame can be adapted by making the two support arms 100 form an included angle.

[0042] Preferably, referring to Figure 2 , wire grooves 120 are provided on one side of the two support arms 100 facing each other, and the wire grooves 120 penetrate through to the wire hiding channel 110. It is convenient to put the wire into the wire hiding channel 110 from the wire grooves 120 or take it out from the wire hiding channel 110. Typically, for further optimization, in order to prevent the wire from coming out of the wire grooves 120, the wire grooves 120 extend from one end of the support arm 100 to the other end of the support arm 100 and are in a wavy line shape.

[0043] In some embodiments, referring to Figure 3 , the support arm 100 is integrally formed, making the entire support arm 100 more integrated and facilitating large-scale production.

[0044] In some embodiments, referring to Figure 3 , the end rotating member 300 includes a rotating part 320 and a fixing plate 330. One end of the rotating part 320 is rotatably connected to the end of the support arm 100, and the other end is fixedly connected to the fixing plate 330. The fixing plate 330 is fixedly connected to the bottom surface of the tabletop or the lower part of the table frame. The rotating part 320 is used to cooperate with the end of the support arm 100 so that two adjacent support arms 100 can rotate relative to each other, and the fixing plate 330 is used to fix the two ends of the wire hiding tube.

[0045] Furthermore, referring to Figure 3, two inner sides at both ends of the middle rotating member 200 are each provided with a rotating shaft 220. A connecting block 130 is provided at the end where the support arm 100 is connected to the middle rotating member 200. A rotating hole 131 is provided through the connecting block 130. The rotating hole 131 is sleeved on the rotating shaft 220 and can pivot around the rotating shaft 220, so as to realize the rotational cooperation between the middle rotating member 200 and the support arm 100. In addition, a limiting protrusion 221 is provided at the end of the rotating shaft 220. The limiting protrusion 221 and the inner side surface of the middle rotating member 200 can respectively abut and cooperate with the surface of the connecting block 130 to restrict the position of the connecting block 130 in the axial direction of the rotating shaft 220. By using the cooperation between the limiting protrusion 221 and the inner side surface of the end of the middle rotating member 200, the support arm 100 can rotate around the rotating shaft 220 and can avoid the separation between the support arm 100 and the middle rotating member 200.

[0046] In actual use, the middle rotating member 200 that frequently deforms is easily damaged. For this reason, with reference to Figure 4 , multiple outwardly protruding reinforcing ribs 230 are provided on the outer surface of the middle rotating member 200 to strengthen the overall structural strength of the middle rotating member 200.

[0047] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art to which the present invention pertains, various changes can be made without departing from the purpose of the present invention.
