[0002] Electric height-adjustable desks are pieces of furniture with automatic desktop height adjustment capabilities, primarily used in office and study settings. They aim to help users alternate between sitting and standing to alleviate health problems caused by prolonged sitting. Electric height-adjustable desks utilize linear drive technology, with motors embedded in the legs. These motors control mechanical devices to adjust the desktop height. Common transmission methods include lead screw drives and rack and pinion drives, with lead screw drives being the most mainstream. These drives use a motor to rotate a lead screw, causing a nut to move along the screw's axis, thus adjusting the desk legs and desktop height. However, existing electric height-adjustable desks are prone to mechanical fatigue and failure under prolonged heavy loads. Additionally, the desktop is susceptible to problems such as tangled wires and cable jams during the height adjustment process, negatively impacting office tidiness. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Example: Reference Figures 1-4The electrically adjustable desk shown includes a connector. From left to right, the upper surface of the connector has a second threaded hole and a first threaded hole. A first screw passes through the internal thread of the first threaded hole. The connector is threaded through the tabletop via the first screw. The tabletop has slots on both sides, with guide rail grooves on the inner walls of the slots. A sliding rod is slidably connected inside the guide rail groove. One end of the sliding rod is fixedly connected to a connector plate. A locking strip is provided on one side of the connector plate, and an extension plate is fixedly connected to the side of the connector plate. A cable management unit is fixed to the bottom of the tabletop. A second screw passes through the internal thread of the second threaded hole, and the connector is threaded through the strip-shaped tabletop via the second screw. A third threaded hole is provided on one side of the connector, with a third screw connected to its internal thread. The connector is threaded through the third screw... A threaded rod passes through a lifting leg, and a telescopic base is fitted onto the surface of the lifting leg. A fourth threaded hole is formed on the surface of the telescopic base, and a fourth screw is threaded into the third threaded hole. A fastener is threaded into the fourth screw. An extension piece 1102 is fixed to the surface of the clamp 1101. One end of the extension piece 1102 has a slot. A connecting rod is passed through the slot of the extension piece, and a pin is passed through both to achieve axial movement, inserting the slider into the slot of the support piece 1106. After aligning the waist hole above the slider with the waist hole above the support piece 1106, a pin is inserted. Then, the horizontal clamp on the other side is inserted into the gap of the slider and the pin is inserted. The locking screw 1107 is screwed into the threaded hole on the side of the support piece 1106 according to the thread direction until it presses against the slider 1104. The slider and the locking screw can then be... A wear-resistant pad is added between 1107 to achieve better applicability. During use, fasteners are fixed to the telescopic base with screws, and the telescopic legs are locked using the clamps at the front of the fasteners. This effectively reduces the risk of motor mechanical failure due to long-term load on the desktop. The telescopic legs also allow for flexible dimensions. An extension piece is fixedly connected to the front of the clamp. A slot is formed on one side of the extension piece, and a first circular hole is formed at the top of the slot. A first pin passes through the inside of the circular hole. A crossbar is concentrically connected to the extension piece via the first pin. A second circular hole is formed at the top of the crossbar, and a second pin passes through the inside of the second circular hole. A slider is concentrically connected to the crossbar via the second pin. A waist hole is formed on the top surface of the slider, and a pin is fixedly connected inside the waist hole. A support piece is slidably connected to the surface of the pin. The support member has a fourth threaded hole on its right side. A locking screw is connected to the support member through the fourth threaded hole to stand the extension plate 6 upright, keeping the plug-in plate 4 facing upwards. It is then inserted into the guide rail inlet groove at the bottom of the tabletop 2. After being moved into the slide rail groove, the tabletop 2 is flipped over to keep the extension plate 6 on the same horizontal plane. The locking strip 5 is then aligned with the slot inside the tabletop 2 to fix it in place. When the extension plate 6 is not needed, the tabletop can be pulled out from the slot and rotated until the extension plate 6 is perpendicular to the tabletop 2. The locking strip on the other side is then inserted into the slot to prevent the extension plate 6 from shaking or shifting. Alternatively, the track groove can be directly cut out to free up space under the tabletop 2. During use, the extension plate is connected to the tabletop via a sliding rod on the plug-in plate, and the locking strip on the plug-in plate can be inserted into the slot when the tabletop is lowered.It can meet the needs of different spaces, is easy to install, and the bottom of the bridging component is connected to a disc. The surface of the disc has an opening, and the inner wall of the opening is threaded to a threaded rod. The surface of the threaded rod is fixedly connected to a gear, and the surface of the gear is meshed with a pull ring pin. A spring is nested outside the pull ring pin, and the spring has a spring chamber outside. The threaded rod is connected to the base plate by threads and is fixed to the bottom of the desktop with a self-tapping screw passing through the screw hole on the top of the bridging component 701. The disc 702 and the bridging component 701 are integrated. The gear 704 is fitted into the screw 703, and the bottom of the screw 703 has threads. The base plate 708 also has threads inside. The screw 703 has fewer threads than the bottom screw 703, allowing for easier fixing based on the difference in thread count. A spring chamber 707 is located at the top of the disc, containing a spring 706. A ring pin 705 is inserted inside the spring. Pulling the ring pin 705 disengages the pin block locked in the gear 704, allowing the lower base 708 to rotate until the cable management position is reached. Releasing the ring pin then secures the lower disc. During use, it is fixed to the bottom of the tabletop with screws. Pulling the ring pin rotates the cable management base, improving the aesthetics and tidiness of the desktop and potentially preventing tripping over cables and preventing wear and tear from prolonged contact with the ground.
[0016] The working principle of this device is as follows: An extension 1102 is fixed to the surface of the clamp 1101. One end of the extension 1102 has a slot. A connecting rod is passed through the slot of the extension, and a pin is passed through both to achieve axial movement, inserting the slider into the slot of the support 1106. The waist hole above the slider is aligned with the waist hole above the support 1106, and a pin is inserted. Then, the horizontal clamp on the other side is inserted into the gap of the slider, and the pin is inserted. The locking screw 1107 is screwed into the threaded hole on the side of the support 1106 according to the thread direction until it presses against the slider 1104. A wear-resistant pad can be added between the slider and the locking screw 1107 for better application. The extension plate 6 is stood upright, with the plug-in plate 4 facing upwards, and inserted into the guide rail inlet slot at the bottom of the table 2. After moving it into the guide rail slot, the table 2 is flipped to keep it level with the extension plate 6. The locking strip 5 is aligned with the slot inside the table 2 to fix it in place. When the extension plate 6 is not needed... The tabletop can be pulled out from the edge of the table and rotated until the extension plate 6 is perpendicular to the tabletop 2. The other side of the clip can be inserted into the slot to prevent the extension plate 6 from shaking or shifting. Alternatively, the track groove can be directly drawn to free up space under the tabletop 2. In this device, self-tapping screws are used to fix the device to the bottom of the tabletop by passing through the screw holes on the top of the bridging component 701. The disc 702 is integrated with the bridging component 701. The gear 704 is fitted into the screw 703, and the bottom of the screw 703 has threads. The base 708 also has threads, but fewer than the threads on the bottom of the screw 703, so that it can be fixed by relying on the difference in the number of threads. There is a spring chamber 707 on the top of the disc. Inside the spring chamber 707 is a spring 706. A ring pin 705 is inserted inside the spring. When the ring pin 705 is pulled, the pin block that is stuck in the gear 704 is pulled out, and the lower base 708 can be rotated until the cable tie position is reached. Then the ring pin can be released to fix the lower disc.
[0017] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
