Description

Technical Field

[0001] The invention relates to a pushing device which is installed on a table or a chair and pushes the table or the chair to rise or fall, and in particular to a pushing device with a wire management component. Background Art

[0002] Traditionally, the push device for lifting tables and chairs mainly uses a motor as a power source, and then transmits the power through a screw rod, so that the connection end fixed to the table or chair can move linearly, and then the table or chair can be adjusted to a lifting height through the connection end of the push device to meet the needs of users.

[0003] However, the push device is internally provided with power cables, signal transmission cables and other wires connected to the external controller. However, the internal space of the push device is limited, or the wires need to move with the connection ends. As a result, the wires are not easily positioned firmly and rub against or get caught in the screw, thereby causing damage to the wires or the push device to fail to operate.

[0004] In view of this, the inventor has devoted himself to studying the above-mentioned prior art and has applied theoretical knowledge to try his best to solve the above-mentioned problems, which has become the goal of the inventor's improvement. Summary of the invention

[0005] The present invention provides a push device with a wire management component, which utilizes spiral winding wire to be wound around the wire management component to firmly position wires and prevent the wires from rubbing against or being wound into a screw rod, thereby allowing the push device to have an excellent service life and aesthetics.

[0006] In an embodiment of the present invention, the present invention provides a pushing device with a wire management component, including: an outer tube; an actuating mechanism accommodated inside the outer tube, the actuating mechanism including a motor and a screw driven to rotate by the motor; a connecting piece accommodated inside the outer tube, the connecting piece and the screw are threadedly connected to each other for transmission and can be lifted and lowered relative to the outer tube; a wire connected to the outer tube and one end of which is fixed to the connecting piece and moves with the connecting piece, the wire having a spiral winding, the spiral winding defining an axis, and the axis is arranged parallel to the screw; and a wire management component, arranged inside the outer tube and arranged in parallel with the axis, the spiral winding being wound around the wire management component.

[0007] Based on the above, the spiral winding wire can be elastically deformed, so the spiral winding wire will shrink or stretch as the wire follows the movement of the linkage. Therefore, a wire management component arranged in parallel with the axis line of the spiral winding wire is used to wind the spiral winding wire around the wire management component, so that the spiral winding wire is restrained by the wire management component and remains upright during the shrinkage or extension process, avoiding the spiral winding wire from curling or tangling together, and thus stably positioning the spiral winding wire, so as to achieve the functions of isolating the wire without an additional mechanism, avoiding the spiral winding wire from rubbing or being entangled in the screw, and hiding the wire in the outer tube, so that the pushing device has an excellent service life and aesthetics.

[0044] The detailed description and technical contents of the present invention will be described as follows with reference to the drawings. However, the drawings are only for illustration purposes and are not intended to limit the present invention.

[0045] Please refer to Figures 1 to 6 As shown, the present invention provides a pushing device with a wire management component. The pushing device 10 mainly includes an outer tube 1, an actuating mechanism 2, a linkage 3, a wire 4 and a wire management component 5.

[0046] like Figures 1 to 3 , Figure 6 As shown, the outer tube 1 is provided with a groove 11, and a clamping member 13 is installed on the top inner wall of the outer tube 1. The groove 11 of this embodiment is a straight line through hole 12, but it is not limited thereto.

[0047] like Figures 2 to 4 , Figure 6 As shown, the actuating mechanism 2 is accommodated inside the outer tube 1, and the actuating mechanism 2 includes a motor 21 and a screw 22 driven to rotate by the motor 21. In this embodiment, the linear through hole 12 and the screw 22 are arranged in parallel, but this is not a limitation.

[0048] like Figures 1 to 4 , Figure 6 As shown, the linking member 3 is accommodated in the outer tube 1 , and the linking member 3 and the screw rod 22 are threadedly connected with each other and penetrate the groove 11 , so that the linking member 3 can move up and down relative to the outer tube 1 .

[0049] The details are as follows. The linkage 3 of this embodiment includes a hollow inner tube 30 and a nut 32. The nut 32 is fixed to the hollow inner tube 30 and is screwed with the screw rod 22 for transmission. A protruding piece 31 extends from the hollow inner tube 30. The protruding piece 31 is inserted into the linear through hole 12. When the linkage 3 and the screw rod 22 are screwed with each other for transmission, the linkage 3 can be lifted and lowered relative to the outer tube 1, and the protruding piece 31 is driven to slide along the linear through hole 12.

[0050] like Figures 1 to 6 As shown, the wire 4 is connected to the outer tube 1 and one end is fixed to the linkage 3 and moves with the linkage 3. The wire 4 has a positioning section 43 engaged with the engaging member 13. The wire 4 also has a spiral winding 41 and a straight line 42 extending from both ends of the positioning section 43. The spiral winding 41 defines an axis L, and the axis L is arranged parallel to the screw 22. Among them, the positioning section 43 of this embodiment has an inverted U shape, but it is not limited to this.

[0051] One end of the spiral winding wire 41 of the present embodiment is connected to the outer tube 1 and the other end is fixed to the linkage 3 and moves with the linkage 3; further explained as follows, one end of the spiral winding wire 41 is extended from the positioning section 43 and connected to the clamping member 13 of the outer tube 1, the other end of the spiral winding wire 41 is fixed to the hollow inner tube 30 of the linkage 3 and moves with the hollow inner tube 30 of the linkage 3, the straight line 42 is passed through the inside of the hollow inner tube 30 and does not move with the hollow inner tube 30, and the ends of the spiral winding wire 41 and the straight line 42 are respectively exposed from the outer tube 1 and are respectively connected to the hand controller and the external control box (not shown in the figure).

[0052] In addition, the engaging member 13 of the present embodiment is a locking block 131 , but the present invention is not limited thereto. The positioning section 43 is engaged with the locking block 131 and is positioned by the locking block 131 .

[0053] like Figures 2 to 4 , Figure 6 As shown, the wire management member 5 is provided inside the outer tube 1 and arranged in parallel with the axial line L, and the spirally wound wire 41 is wound around the wire management member 5 .

[0054] The details are as follows. The wire management component 5 is a straight wire 42 extending from the wire 4 and parallel to the axis L. The spiral winding wire 41 is sleeved and wound around the outside of the straight wire 42 .

[0055] like Figures 2 to 6 As shown, the pushing device 10 of the present invention further includes a stop seat 6, which is arranged between the motor 21 and the hollow inner tube 30 and is used to stop the hollow inner tube 30, thereby preventing the hollow inner tube 30 from colliding with the motor 21 when rising or falling. The stop seat 6 is provided with a through hole 61, and one end of the straight line 42 away from the positioning section 43 is passed through the through hole 61.

[0056] like Figure 1 , Figure 6 As shown, the use state of the pushing device 10 of the present invention is that firstly, the protruding pieces 31 of several pushing devices 10 are fixed to the table top 100. When the motor 21 drives the screw rod 22 to rotate forward or reverse, it will drive the connecting piece 3 to rise or fall relative to the outer tube 1. At the same time, the protruding piece 31 also drives the table top 100 to rise or fall relative to the outer tube 1, thereby achieving the function of automatically adjusting the height of the table top 100.

[0057] In addition, since the spiral winding wire 41 is elastically deformable, the spiral winding wire 41 can shrink as the linkage 3 rises, and can extend as the linkage 3 falls, that is, the spiral winding wire 41 will shrink or extend as the wire 4 moves along with the linkage 3. Therefore, the straight line 42 is arranged in parallel with the axis line L of the spiral winding wire 41, and the spiral winding wire 41 is sleeved and wound on the outside of the straight line 42, so that the spiral winding wire 41 is restrained by the straight line 42 during the shrinkage or extension process and remains in an upright state, thereby preventing the spiral winding wire 41 from being curled or entangled, and thus stably positioning the spiral winding wire 41, so as to achieve the functions of isolating the wire 4 without an additional mechanism, preventing the spiral winding wire 41 from rubbing or being drawn into the screw 22, and hiding the wire 4 in the outer tube 1, so that the pushing device 10 has an excellent service life and aesthetics.

[0058] Please refer to Figures 7 and 8 FIG. 1 is another embodiment of the push device 10 of the present invention. Figures 7 and 8 Examples and Figures 1 to 6 The embodiments are roughly the same, Figures 7 and 8 Examples and Figures 1 to 6 The embodiment of the present invention is different in that the structure of the wire management component 5 is different. The spiral wire 41 of this embodiment is not sleeved and is wound outside the straight wire 42.

[0059] One end of the spiral winding wire 41 of the present embodiment is connected to the outer tube 1 and the other end is fixed to the connecting member 3 and moves with the connecting member 3; further explained as follows, the wire management component 5 includes a straight wire 42 extending from the wire 4 and parallel to the axial line L and a plurality of fixing rings 51 sleeved on the spiral winding wire 41 and the straight wire 42, so that one side of the plurality of fixing rings 51 is sleeved on the spiral winding wire 41 and the other side is sleeved on the straight wire 42.

[0060] Thus, the spiral winding wire 41 drives the plurality of fixing rings 51 to move on the straight line 42 during the process of contraction or extension, and is restrained by the plurality of fixing rings 51, and the plurality of fixing rings 51 are restrained by the straight line 42 to maintain an upright state, thereby preventing the spiral winding wire 41 from curling or tangling, thereby achieving the same Figures 1 to 6 The functions and effects of the embodiments.

[0061] Please refer to Figures 9 and 10 FIG. 1 is another embodiment of the push device 10 of the present invention. Figures 9 and 10 Examples and Figures 1 to 6 The embodiments are roughly the same, Figures 9 and 10 Examples and Figures 1 to 6 The embodiment of the present invention is different in that the structure of the wire management component 5 is different. The spiral wire 41 of this embodiment is not sleeved and is wound outside the straight wire 42.

[0062] in addition, Figures 9 and 10 Examples and Figures 1 to 6 The embodiment of the present invention is further different in that one end of the straight line 42 is connected to the outer tube 1 and the other end is fixed to the linkage 3 and moves with the linkage 3; the details are as follows: one end of the straight line 42 is extended from the positioning section 43 and connected to the engaging member 13 of the outer tube 1, the other end of the straight line 42 is fixed to the hollow inner tube 30 of the linkage 3 and moves with the hollow inner tube 30 of the linkage 3, the spiral winding wire 41 is passed through the interior of the hollow inner tube 30 and does not move with the hollow inner tube 30, and the end of the spiral winding wire 41 away from the positioning section 43 is passed through the through hole 61 of the stop seat 6.

[0063] Furthermore, the wire management component 5 is a positioning shaft 52 accommodated inside the outer tube 1 and parallel to the axis L. The spiral winding 41 is sleeved and wound around the outside of the positioning shaft 52. The positioning shaft 52 passes through the inside of the hollow inner tube 30 and does not move with the hollow inner tube 30.

[0064] Furthermore, the engaging member 13 of the present embodiment is a roller 132, and the positioning section 43 is engaged with the roller 132 and can slide relative to the roller 132. Therefore, when the straight line 42 follows the linkage 3 to rise, it will slide toward the spiral winding wire 41 through the roller 132 and release the spiral winding wire 41, thereby contracting the spiral winding wire 41; when the straight line 42 follows the linkage 3 to descend, it will slide away from the spiral winding wire 41 through the roller 132 and tighten the spiral winding wire 41, thereby extending the spiral winding wire 41, that is, the spiral winding wire 41 will contract or extend because the wire 4 follows the movement of the linkage 3.

[0065] Thus, the spiral winding wire 41 is restrained by the positioning shaft 52 during the process of contraction or extension and remains upright, thereby preventing the spiral winding wire 41 from curling or tangling, thereby achieving the same Figures 1 to 6 The functions and effects of the embodiments.
