Detailed Implementation

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] like Figures 1 to 6As shown, a table leg with built-in retractable cable includes: a height adjustment device 100, the height adjustment device 100 is arranged as a telescopic structure; a telescopic protection device 200, the telescopic protection device 200 includes a first protection pipe 210 and a second protection pipe 220, the first protection pipe 210 and the second protection pipe 220 are slidingly connected, the first protection pipe 210 is fixedly connected with a part of the height adjustment device 100, the second protection pipe 220 is fixedly connected with another part of the height adjustment device 100, the telescopic protection device 200 is arranged to be telescopic with the height adjustment device 100; a telescopic cable 300, the telescopic cable 300 is arranged in the telescopic protection device 200, and both ends of the telescopic cable 300 respectively extend from both ends of the telescopic protection device 200.

[0031] The height adjustment device 100 is actually a lifting table transmission screw rod assembly 110, which is a device for driving two sections of pipe to expand or retract by using a screw rod, and belongs to an existing element in a lifting table leg.

[0032] The telescopic protection device 200 mainly plays a role of protecting, managing and restricting the telescopic cable 300, and is designed as a two-section pipe structure composed of the first protection pipe 210 and the second protection pipe 220, the first protection pipe 210 and the second protection pipe 220 are fixedly connected with different parts of the height adjustment device 100, so that the first protection pipe 210 and the second protection pipe 220 can slide relative to each other when the height adjustment device 100 is telescopic.

[0033] The telescopic cable 300 is arranged in the telescopic protection device 200, and then the telescopic protection device 200 can be installed in the leg pipe 400 of the table leg, so as to realize the effect of cable wiring in the table leg, and the telescopic cable is protected by the telescopic protection device 200 in the table leg, avoiding damage of the cable caused by external environment (such as wear and tear, etc.), and reducing safety hazards.

[0034] The design of the built-in telescopic cable 300 makes the table leg and the surrounding area without messy wires exposed outside, improves the overall appearance and safety of the product, and the telescopic protection device 200 can protect the telescopic cable 300 and limit and guide the telescopic cable 300, so that the telescopic cable 300 can only be telescopic in the telescopic protection device 200, which is very important for protecting the telescopic cable 300.

[0035] When the height adjusting device 100 is telescoped (i.e. the table leg is lifted or lowered), the telescopic protection device 200 is also telescoped, and the telescopic cable 300 is also telescoped. Since the telescopic cable 300 is placed inside the telescopic protection device 200, it is ensured that the telescopic cable 300 is not damaged during the height adjustment process, i.e. no matter how long the telescopic cable 300 is stretched, the telescopic protection device 200 can adaptively adjust its length to maximize the protection of the telescopic cable 300.

[0036] It is important to note here that although there are also cable-in-pipe designs in the prior art that place the cable inside a protective tube, the fixed-length protective tube cannot adapt to the change in cable length during the lifting and lowering of the table leg, resulting in part of the cable being exposed when the table leg is raised, increasing the risk of cable damage. In the present solution, the telescopic two-section protective tube structure ensures that the cable remains inside the protective tube most of the time, regardless of the height of the table leg, thereby avoiding damage to the cable caused by external environmental factors (such as wear and tear, pulling, etc.). The two-section protective tube can automatically adjust its length according to the height change of the table leg, ensuring that the cable is well protected and managed in different working states.

[0037] On the basis of the above-mentioned embodiments, the height adjusting device 100, the telescopic protection device 200, and the telescopic cable 300 form an integral module. Since the height adjusting device 100, the telescopic protection device 200, and the telescopic cable 300 have been integrated together, during installation, only the integral module needs to be inserted directly into the leg tube 400 and ensure that it is properly fixed. There is no need to separately install the telescopic protection device 200 and the cable, greatly reducing the installation steps and time. The installer does not need to deal with complex wiring or assembly issues, only needs to focus on the docking between the integral module and the leg tube 400, making the installation extremely simple.

[0038] As shown in Figures 1 to 4 , Figure 6 , on the basis of the above-mentioned embodiments, the height adjusting device 100 includes a lead screw assembly 110, a first telescopic tube 120, and a second telescopic tube 130. The first telescopic tube 120 is slidingly connected to the second telescopic tube 130, and the lead screw assembly 110 is threadedly connected to the first telescopic tube 120 and the second telescopic tube 130. When the lead screw assembly 110 rotates, the lead screw assembly 110 telescopes relative to the first telescopic tube 120, and the first telescopic tube 120 telescopes relative to the second telescopic tube 130.

[0039] The height adjusting device 100 is actually a lifting table transmission lead screw assembly 110, which is part of the prior art and will not be described here.

[0040] As shown in Figure 1 , Figure 2 , Figure 4 ,Figure 5 As shown, based on the above embodiment, the lead screw assembly 110 is axially fixedly provided with a mounting base 140, the first protective tube 210 is fixedly connected to the mounting base 140, and the second protective tube 220 is fixedly connected to the first telescopic tube 120 or the second telescopic tube 130.

[0041] In this embodiment, the first protective tube 210 is axially fixedly connected to the lead screw assembly 110 via the mounting base 140, and the second protective tube 220 is fixedly connected to the first telescopic tube 120 or the second telescopic tube 130. This means that when the height adjustment device 100 extends or retracts, the first protective tube 210 moves with the movement of the lead screw assembly 110, and the second protective tube 220 moves with the movement of the first telescopic tube 120 or remains fixed, so that the first protective tube 210 and the second protective tube 220 can slide relative to each other as the height adjustment device 100 extends or retracts.

[0042] Based on the above embodiments, the height adjustment device 100 is provided with a first cable fixing member 150 and a second cable fixing member 160 at both ends, one end of the retractable cable 300 passes through the first cable fixing member 150, and the other end of the retractable cable 300 passes through the second cable fixing member 160.

[0043] In this embodiment, the first cable fastener 150 and the second cable fastener 160 can limit the two ends of the retractable cable 300, preventing unnecessary movement or displacement of the cable during the lifting and lowering of the table legs. This helps to maintain the stability of the cable's position and prevents it from being damaged by pulling or twisting. In this example, the first cable fastener 150 is mounted on the mounting base 140, and the second cable fastener 160 is mounted on the input socket 411.

[0044] like Figures 1 to 6 As shown, based on the above embodiment, it also includes a leg tube 400. The leg tube 400 includes a first tube body 410, a second tube body 420, and a third tube body 430 that are slidably connected in sequence. The height adjustment device 100 and the telescopic protection device 200 are both installed inside the leg tube 400. The second telescopic tube 130 is fixedly connected to the first tube body 410, the first telescopic tube 120 is fixedly connected to the second tube body 420, and the mounting base 140 is fixedly connected to the third tube body 430.

[0045] The leg tube 400 is designed as a three-section tube structure. During the lifting and lowering process, the first tube 410 is in contact with the ground and remains stationary. The motor drives the height adjustment device 100 to extend and retract, thereby causing the second tube 420 and the third tube 430 to extend and retract. As the height of the table legs changes, the lengths of the retractable protection device 200 and the retractable cable 300 also change, thus providing continuous protection for the cable.

[0046] On the basis of the above-mentioned embodiment, the motor box 500 is further included, the mounting seat 140 is fixedly connected with the motor box 500, the motor box 500 is located at the top end of the third pipe body 430 and is provided with an output socket 510, the bottom end of the first pipe body 410 is provided with an input socket 411, and the two ends of the telescopic cable 300 are electrically connected with the output socket 510 and the input socket 411 respectively.

[0047] The output socket 510 and the input socket 411 are located at the top and the bottom of the table leg respectively, the input socket 411 is electrically connected with an external power supply, the power supply can be introduced into the output socket 510 through the telescopic cable 300 built in the table leg, and the exposed cable of the lifting table is reduced through the design, so that the whole table is clean and tidy.

[0048] As shown in Figure 1 , Figure 5 On the basis of the above-mentioned embodiment, the telescopic cable 300 is provided in a spiral spring shape. The spiral spring shape allows the cable to automatically extend or contract according to the height change of the table leg, without the need for additional mechanical devices to manage the cable length. This adaptive feature ensures that the cable is always under proper tension and will not be damaged by excessive stretching or compression.

[0049] As shown in Figures 1 to 6 On the basis of the above-mentioned embodiment, an electric lifting table with a built-in telescopic cable is provided.

[0050] The table leg of the electric lifting table can be lifted, the lifting of the table leg can be realized through the motor and the height adjusting device 100, and the telescopic protection device 200 and the telescopic cable 300 are telescoped together to adapt to the height change of the table leg when the table leg is lifted. The telescopic cable 300 is built in the table leg, the simplicity of the appearance of the table leg is maintained, and the telescopic protection device 200 can protect the telescopic cable 300.

[0051] In addition, since the height adjusting device 100, the telescopic protection device 200 and the telescopic cable 300 are integrated together to form an integral module in the present scheme, the integral module can be directly assembled with the leg pipe 400 during assembly, thereby simplifying the installation process and reducing the installation steps and time.
