In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0031] The utility model discloses a lifting column with internal wiring. A plurality of wires inside the lifting column can be accommodated by a drag chain, which greatly reduces the volume and weight of the lifting column and solves the problem of large volume and weight caused by the large number of spring wires used in the prior art lifting column.

[0032] The first embodiment, as Figure 1 The lifting column shown in FIG. 1 includes: a first tube section 100, a second tube section 200, a driving mechanism 300, a control unit 400, a wire and a drag chain 500, wherein the control unit 400 is a circuit board. Figure 1 and 2 The circuit board is shown mounted in the cover.

[0033] The first tube section 100 is sleeved on the second tube section 200 , and the driving mechanism 300 , the control unit 400 , the wires and the drag chain 500 are disposed in the first tube section 100 and the second tube section 200 .

[0034] The driving mechanism 300 and the drag chain 500 are connected to the first tube section 100 and the second tube section 200 . The driving mechanism 300 is used to drive the second tube section 200 to move up and down, and the drag chain 500 is used to accommodate the wires.

[0035] The control unit 400 is installed on the first tube section 100 and / or the second tube section 200, and the driving mechanism 300 and the control unit 400 are connected by wires. A sensor can also be set on the lifting rod, and the sensor and the control unit 400 are connected by wires.

[0036] In this embodiment, if Figure 1 The lifting column shown further includes: a guide column 600 , the bottom end of the guide column 600 is connected to the first section tube 100 , the top end of the guide column 600 extends toward the second section tube 200 , and a vertical guide groove is provided on one side of the guide column 600 .

[0037] One end of the drag chain 500 is connected to the top of the guide column 600, and the other end is connected to the second section pipe 200. The end of the drag chain 500 close to the guide column 600 is arranged in a vertical guide groove, which is used to guide the drag chain 500.

[0038] By partially arranging the drag chain 500 in the vertical guide groove of the guide column 600, the drag chain 500 can be limited laterally during its movement to achieve guidance of the drag chain 500, further reducing the interference rate between the drag chain 500 and the internal structure of the lifting column, and reducing the lateral displacement of the drag chain 500, thereby improving the working stability of the lifting column and the service life of the drag chain 500.

[0039] In this embodiment, if Figure 1 The illustrated drive mechanism 300 is a push rod motor.

[0040] Working principle: One end of the wire is set as the moving end in the drag chain 500, and the other end is set as the fixed end on the guide column 600. When the driving mechanism 300 drives the second section tube 200 to rise and fall, only the moving end of the wire moves with the drag chain 500. During the movement of the drag chain 500, the guide column 600 limits the drag chain 500 laterally.

[0041] In the second embodiment, based on the first embodiment, guide wheels 700 are used to replace the guide posts 600.

[0042] like Figure 2 The lifting column shown in the figure further includes: a guide wheel 700, which is connected to the driving mechanism 300 or the first section tube 100, and a circumferential guide groove is provided on the guide wheel 700. Figure 3 The guide wheel 700 is connected to the driving wheel via a pin.

[0043] One end of the drag chain 500 is connected to the first section pipe 100 , and the other end is connected to the second section pipe 200 . The drag chain 500 is arranged around the guide wheel 700 so that the middle part of the drag chain 500 is arranged in the circumferential guide groove.

[0044] exist Figure 3 In the illustrated embodiment, the drive mechanism 300 is a sprocket chain drive mechanism 300 or a synchronous belt drive mechanism 300 .

[0045] The driving mechanism 300 includes a driving wheel 301, and a chain or synchronous belt arranged around the driving wheel 301. The guide wheel 700 and the driving wheel 301 are coaxially arranged. The driving mechanism 300 includes: a motor connected to the driving wheel 301, a chain or synchronous belt arranged around the driving wheel 301, the driving wheel 301 is a sprocket or a synchronous wheel, and the motor drives the first section tube 100 and the second section tube 200 to move through the driving wheel, chain or synchronous belt.

[0046] like Figure 3 The guide wheel 700 is connected to the driving mechanism 300. In a specific embodiment, a support rod can be provided to connect the guide wheel 700 to the driving mechanism 300 or the first section pipe 100 through the support rod.

[0047] By partially arranging the drag chain 500 in the circumferential guide groove of the guide wheel 700, the drag chain 500 can be limited laterally during its movement to achieve guidance of the drag chain 500, further reducing the interference rate between the drag chain 500 and the internal structure of the lifting column, and reducing the lateral displacement of the drag chain 500, thereby improving the working stability of the lifting column and the service life of the drag chain 500.

[0048] The guide wheels 700 can support the drag chain 500 with a larger span while reducing the volume and weight of the guide structure, further ensuring the working stability of the drag chain 500.

[0049] In the third embodiment, a third tube section 800 is added on the basis of the first embodiment, and a guide wheel 700 is used instead of the guide column 600.

[0050] like Figure 4 The lifting column shown also includes: a third tube section 800, the second tube section 200 is sleeved on the third tube section 800, the bottom end of the first tube section 100 is provided with a bottom plate 101, the bottom end of the second tube section 200 is provided with a middle plate 201, and the top end of the third tube section 800 is provided with a top plate 801. The push rod motor is installed on the second tube section 200 and the third tube section 800 through the middle plate 201 and the top plate 801, and the synchronous wheel is installed on the second tube section 200 through the middle plate 201.

[0051] The driving mechanism 300 includes a push rod motor, a driven wheel 900 , a chain or a synchronous belt, a first support rod 901 and a second support rod 902 .

[0052] The push rod motor is installed on the third tube section 800 and the second tube section 200 .

[0053] The driven wheel 900 is mounted on the second tube section 200. The two driven wheels 900 are mounted on the same synchronous fixing bracket and are mounted on the second tube section 200 through the synchronous fixing bracket. The driven wheel 900 is a sprocket or synchronous wheel that cooperates with a chain or synchronous belt.

[0054] A chain or a synchronous belt is arranged around the driven wheel 900 , and the chain or the synchronous belt is installed on the first support rod 901 and the second support rod 902 .

[0055] The first support rod 901 is installed on the first tube section 100 , and the second support rod 902 is installed on the third tube section 800 .

[0056] like Figure 5The guide wheel 700 is connected to the driven wheel 900 via a pin.

[0057] In this embodiment, the drag chain 500 is installed on the first tube section 100 and the third tube section 800 .

[0058] The guide wheels 700 can support the drag chain 500 with a larger span while reducing the volume and weight of the guide structure, further ensuring the working stability of the drag chain 500.

[0059] Working principle: When the lifting column with the third-section tube 800 needs to be increased in length, the push rod motor drives the third-section tube 800 to move away from the first-section tube 100. At this time, the third-section tube 800 drives the chain or synchronous belt to move around the driven wheel 900. The chain or synchronous belt, the first synchronous support rod and the second synchronous support rod cooperate to drive the second-section tube 200 to move away from the first-section tube 100, thereby increasing the overall length of the lifting column. During this process, the third-section tube 800 drives the end of the drag chain 500 to move, and the guide wheel 700 drives the middle part of the drag chain 500 to move.

[0060] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims.
