[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0020] See also Figure 1-5 The utility model embodiment provides a technical solution: the herringbone art table leg comprises a supporting plate 1, a connecting member 5 is provided at the bottom of the supporting plate 1, two supporting legs 3 are connected on both sides of the connecting member 5 in reverse rotation, and an adjusting mechanism is provided in the two supporting legs 3, and the two adjusting mechanisms include a second gear 9, two third gears 10, a first rotating shaft 16, an adjusting block 15, a connecting rod 12 and a knob 13. The first rotating shaft 16 is rotatably connected to the bottom end of the supporting leg 3, and the first rotating shaft 16 is sleeved with two third gears 10 and the adjusting block 15. The adjusting block 15 is located between the two third gears 10, and the second gear 9 is slidably and rotatably connected in the supporting leg 3. The connecting rod 12 is fixedly arranged between the second gear 9 and the knob 13. During the sliding process of the second gear 9, the second gear 9 can mesh with any one of the third gears 10. When the second gear 9 meshes with the third gear 10 far away from the knob 13, the knob 13 is clamped with the supporting leg 3.
[0021] As a preferred technical solution, a limit assembly is provided between the two knobs 13 and the two supporting legs 3. The two limit assemblies include a card block 14. The card block 14 is fixedly connected to one end of the knob 13 close to the supporting leg 3. A plurality of card slots 17 are provided in a circular array on one side of the supporting leg 3 close to the knob 13. The card block 14 can be engaged with any card slot 17. Specifically, when adjusting the angle of the adjustment block 15, the knob 13 is pushed to make the card block 14 engage with the corresponding card slot 17. At this time, the second gear 9 is engaged with the third gear 10 which is farther away from the knob 13 to lock it, and at the same time fix the rotation angle of the adjustment block 15.
[0022] As a preferred technical solution, both knobs 13 are provided with anti-slip grooves. Specifically, the anti-slip grooves can increase the friction between the operator's hand and the knob 13, making it easier for the operator to rotate the knob 13.
[0023] As a preferred technical solution, a rack 4 is vertically slidably connected in the connecting member 5, and first gears 7 are meshed on both sides of the rack 4. Second rotating shafts 11 are passed through the two first gears 7, and the top ends of the two supporting legs 3 are snap-fitted with one ends of the two second rotating shafts 11 in a one-to-one correspondence. A driving member for driving the rack 4 to slide is provided on the supporting plate 1. Specifically, a fixed seat 8 is provided on both sides of the connecting member 5, and the two second rotating shafts 11 are rotatably connected in the two fixed seats 8 respectively. Teeth are provided on both sides of the rack 4, and a groove is provided on the top ends of the two supporting legs 3. The two grooves are snap-fitted with the two second rotating shafts 11 in a one-to-one correspondence. The positions of the two supporting legs 3 are staggered, which can make the supported table top more balanced.
[0024] As a preferred technical solution, the driving member includes a screw 2, a sliding groove 6 is vertically opened in the connecting member 5, the screw 2 is rotatably connected in the sliding groove 6, the rack 4 is slidably connected in the sliding groove 6, and the two sides of the rack 4 are in contact with the inner walls of the two sides of the sliding groove 6, the rack 4 is threadedly connected to the screw 2, specifically, when the screw 2 is rotated, the sliding groove 6 limits the circumferential rotation of the rack 4, so that the screw 2 spirally drives the rack 4 to make a vertical linear motion, which can simultaneously drive the first gears 7 on both sides to rotate in the opposite direction, thereby realizing the height adjustment of the overall device.
[0025] Working principle: The herringbone art table leg rotates the screw 2. Since the slide groove 6 limits the circumferential rotation of the rack 4, the screw 2 spirally drives the rack 4 to make a vertical linear motion, which can simultaneously drive the first gears 7 on both sides to rotate in the opposite direction to achieve the height adjustment of the overall device. The knob 13 on the severely worn support leg 3 is rotated to drive the second gear 9 to rotate. The third gear 10 closer to the knob 13 is driven by the second gear 9 to rotate, so as to achieve the angle adjustment of the adjustment block 15, raise the height of the severely worn support leg 3, balance the table top, push the knob 13, and make the block 14 engage with the corresponding slot 17. At this time, the second gear 9 is meshed with the third gear 10 farther away from the knob 13 to lock it, and at the same time fix the rotation angle of the adjustment block 15.
[0026] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
