Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Please see attached Figure 1-8 The utility model provides an embodiment: a new type of electric lifting table, including a panel 1, a first supporting leg 2, and a second supporting leg 3. Two wire holes 101 are arranged on the panel 1, which facilitate the wired devices on the panel 1 to be routed to the bottom of the panel 1 through the wire holes 101, so as to keep the surface clean. A curved portion 102 is arranged on the outer edge to increase the curve beauty of the desktop and make the entire electric lifting table look more fashionable and attractive. The panel 1 is usually made of high-strength, wear-resistant materials, such as density boards, artificial wood boards or metal sheets, which have sufficient firmness and durability to meet the requirements of daily use and work. The panel 1 is arranged on the top of the first supporting leg 2 and the second supporting leg 3. The first supporting leg 2 and the second supporting leg 3 serve as the supporting base of the lifting table and have sufficient stability and load-bearing capacity. The supporting legs are made of solid metal materials, such as aluminum alloy. The first supporting leg 2 and the second supporting leg 3 are fixedly connected to the panel 1 through the first lifting frame 8 and the second lifting frame 9 respectively. A connecting rod 10 is arranged between the first lifting frame 8 and the second lifting frame 9. A synchronous shaft 7 parallel to the connecting rod 10 is arranged on one side of the connecting rod 10. The synchronous shaft 7 is connected to the driving motor 5. The driving motor 5 is electrically connected to the controller 6. The function of the synchronous shaft 7 is to ensure that the lifting and lowering movements of the two lifting frames are synchronized and smooth. The forward and reverse rotations of the driving motor 5 are controlled by the controller 6, so as to realize the height adjustment of the lifting table.

[0024] Specifically, the connecting rod 10 includes a first square tube 1001, a second square tube 1002, and an adjustment tube 1003 movably nested and connected between the first square tube 1001 and the second square tube 1002. The first square tube 1001 and the second square tube 1002 are respectively provided with a second connecting member 1004 and a third connecting member 1005, and the panel 1 and the connecting rod 10 can be fixed with screws through the second connecting member 1004 and the third connecting member 1005.

The first square tube 1001, the second square tube 1002, and the adjustment tube 1003 of fixed length are telescopically combined into connecting rods 10 of different total lengths, which can basically meet the requirements of most customers on the market for the length of the desktop, realize customized requirements through standard parts, improve production efficiency, and reduce production costs.

[0025] The first supporting foot 2 and the second supporting foot 3 have the same structure, and are respectively connected to the first pad 201 and the second pad 301 at the bottom, the first lifting frame 8 and the second lifting frame 9 are respectively slidably nested in the first supporting foot 2 and the second supporting foot 3, and the first lifting frame 8 and the second lifting frame 9 are respectively installed with a lifting drive mechanism 13, the lifting drive mechanism 13 is connected to the synchronous shaft 7, and the driving motor 5 is fixedly connected to one side of one of the lifting drive mechanisms 13 through a right-angle connector 11. Two leveling feet 4 are respectively arranged at the bottom of the first pad 201 and the second pad 301. The pads can be made of solid materials, such as steel plates or aluminum plates, to increase the stability and carrying capacity of the supporting feet.

[0026] The first lifting frame 8 has the same structure as the second lifting frame 9. The first lifting frame 8 includes a vertical rod 801, a horizontal rod 802, and a first connecting member 803. The vertical rod 801 is slidably nested in the first supporting foot 2. The horizontal rod 802 is located at the top of the vertical rod 801 and is perpendicular to the vertical rod 801. The first connecting member 803 is located at the connection between the vertical rod 801 and the horizontal rod 802. The first connecting member 803 remains perpendicular to the vertical rod 801 and the horizontal rod 802 at the same time. The first connecting member 803 is a right-angled type and is matched with the connecting rod 10.

[0027] A connecting rod 10 is arranged between the first lifting frame 8 and the second lifting frame 9, and the connecting rod 10 includes a first square tube 1001 and a second square tube 1002. One end of the first square tube 1001 is connected to the first connecting piece 803, and the end of the second square tube 1002 away from the first connecting piece 803 is connected to the connecting piece of the second lifting frame 9. An adjusting tube 1003 is arranged in the middle of the connecting rod 10, and the adjusting tube 1003 is parallel to the cross bar 802 and the cross bar of the second lifting frame 9.

[0028] The design of the first lifting frame 8, the second lifting frame 9 and the connecting rod 10 increases the stability and rigidity of the overall structure and ensures the synchronous movement between the lifting frames.

[0029] The lifting drive mechanism 13 includes a screw rod 1302, an inverted nut 1303, a first plastic bearing 1304, and a second plastic bearing 1305. The inverted nut 1303 is fixedly connected to the first lifting frame 8 or the second lifting frame 9. The inverted nut 1303 passes through the screw rod 1302, and the screw rod 1302 is perpendicular to the first supporting leg 2 and the second supporting leg 3. A long shaft gear 1306 is arranged between the first plastic bearing 1304 and the second plastic bearing 1305. The long shaft gear 1306 is meshed with the lifting gear 1307 at the top of the inverted nut 1303. The synchronous shaft 7 is matched with the first plastic bearing 1304 and the second plastic bearing 1305 through a hexagonal screw hole. A housing 1301 is arranged on the top of the two lifting drive mechanisms 13 to wrap the internal gear set. The housing 1301 is fixedly connected to the first lifting frame 8 and the second lifting frame 9. A third bearing 1308 is arranged below the lifting gear 1307. The power of the driving motor 5 is transmitted to the lifting driving mechanism 13 at both ends through the synchronous shaft 7, further driving the long shaft gear 1306 to rotate, and finally the lifting gear 1307 drives the screw rod 1302 to rotate. Since the inverted nut 1303 is fixedly connected to the first lifting frame 8 and the second lifting frame 9, when the screw rod 1302 rotates, due to the torque, the inverted nut 1303 can move up and down with the forward and reverse rotation of the driving motor 5, thereby causing the first lifting frame 8, the second lifting frame 9 to move relative to the first supporting foot 2, the second supporting foot 3, thereby achieving the effect of lifting and lowering the panel 1.

[0030] The controller 6 includes a button 601 , and the controller 6 is electrically connected to the drive motor 5 via an electric control element.

[0031] A guide ring 12 is provided between the first lifting frame 8 and the first supporting leg 2, and the guide ring 12 includes a transition outer edge 1201 and a buckle 1202. The transition outer edge 1201 surrounds the first lifting frame 8 or the second lifting frame 9, and the buckle 1202 is matched with the first supporting leg 2 or the second supporting leg 3. The guide ring 12 is made of plastic with self-lubricating properties to ensure that the lifting frame is smooth and stable during the lifting process.

[0032] The specific working method of the utility model is as follows: after placing the lifting table, use the leveling foot 4 to level the lifting table as a whole to avoid shaking. After connecting the power supply, the controller 6 will enter the power-on state, including the rising and falling functions. Long pressing the button 601 to rise and fall can control the drive motor 5 to drive the synchronous shaft 7 to rotate the gears of the two lifting drive mechanisms 13, and use the screw rod 1302 to drive the inverted nut 1303 to move up and down, so that the first lifting frame 8, the second lifting frame 9 and the first support foot 2, the second support foot 3 have a height difference, thereby realizing the height control of the panel 1, and releasing the rising and falling buttons can stop. The overall design of the lifting table is simple and practical, easy to transport and assemble, with good functional effects, and suitable for different office and entertainment needs.
