Detailed Description

As shown in figures 1-2, the small lifting table comprises a table plate 10, a lifting mechanism, a locking structure, a power mechanism and a profile frame, wherein the lifting mechanism comprises four connecting arms 2 and steel shafts 6 which are arranged on two sides of the bottom of the table plate in a crossing way, the crossing part of the connecting arms 2 is hinged by the steel shafts 6, the bottoms of the two connecting arms 2 which are not crossed on one side of the table plate are hinged with a lower fixed bracket 5, the top parts of the two connecting arms are hinged with a sliding rail lower bracket 13 through an upper connecting shaft 7, the upper ends of the two connecting arms can slide relatively linearly with the table plate, the tops of the two connecting arms 2 on the other side are hinged with an upper connecting bracket 8, the upper connecting bracket 8 is fixed on the bottom surface of the table plate 10 through connecting bolts 9, the bottom is connected with the lower connecting shaft 3, rollers 4 are arranged at two ends of the lower connecting shaft 3, the rollers 4 are arranged in the profile frame 1, the rollers 4 can roll in the profile frame, the lower ends of the two connecting arms can slide relatively linearly with the profile frame, the desk plate 10 can move up and down relative to the section frame 1 by connection and assembly, the track of the front, back, left and right is limited, the locking structure comprises a slide rail upper bracket 11, a slide rail 12, a slide rail lower bracket 13 and a locking machine 14, the slide rail upper bracket 11 is fixed on the bottom surface of the desk plate 10, the slide rail lower bracket 13 is fixed on the bottom of the slide rail upper bracket 11 through the slide rail 12, so the desk plate can slide relatively linearly and relatively smoothly, the locking machine 14 is arranged on the bottom of the slide rail upper bracket 11, a lock tongue of the locking machine 14 in a conventional state extends out and can be inserted into a gear hole of the slide rail lower bracket 13, so that the slide rail upper bracket 11 and the slide rail lower bracket 13 can not slide relatively, the desk plate can not be lifted, the locking machine 14 is connected with a handle rocker 18 on a handle fixing seat 19 through a steel wire cable 15, the handle rocker 10 can rotate around the handle fixing seat 19 to pull the steel cable 15, the spring bolt of the locking machine 14 can be retracted by pulling the steel wire rope stay 15 so as to prevent the relative sliding of the upper sliding rail support 11 and the lower sliding rail support 13, and then the table plate can be lifted up and down, the power mechanism comprises a mechanical torsion spring 21, a gas spring 22 and a mechanical tension spring 23, the mechanical torsion spring 21 is arranged at the middle hinging position of the connecting arm 2, one end of the gas spring 22 is fixed on the lower sliding rail support 11, the other end of the gas spring is fixed on the connecting arm 2, the end of the mechanical tension spring 23 is fixed on the end of the lower connecting shaft 3, the gas spring 22 and the mechanical tension spring 23 are matched for use, the power is strong, the buffering effect is ensured, the whole table is ultrathin, the force arm of the gas spring 22 providing power in the range of the table top which is just lifted up is very small or even zero, the lifting force quantity is insufficient, and the mechanical torsion spring 21 is applied at the middle hinging position of the connecting arm 2, so the whole lifting process is stressed relatively uniformly, without clamping or noise.

The steel wire inhaul cable 15 is provided with an inhaul cable adjusting baffle 16, and the handle fixing seat 19 is provided with a handle sealing cover 17.

The connecting arm 2 is provided with a torsion spring decorative shell 20 matched with a mechanical torsion spring 21.

The profile frame 1 is provided with a handle lock 24 which is matched with the handle rocker 18.

When the device is used, after the handle rocker arm 18 is loosened after the device is adjusted to a proper height, the lock tongue of the locking machine 14 is ejected again to prevent the sliding rail upper bracket 11 from sliding relative to the sliding rail lower bracket 13 so as to be fixed at the position. When the table top is at the lowest, the hook on the handle rocker arm 18 automatically hangs the handle lock catch 24, so that the table top is fixed at the position, and the handle rocker arm 18 is unlocked to be shifted.

The invention has good fitting property, convenient adjustment, easy height adjustment, stable height adjustment process and no noise, and can smoothly and smoothly lift and smoothly realize no jamming through the advantageous combination of various driving forces, so that the operation is more convenient, the lifting structure is not required to be adjusted with great force, and the office experience of one button is obtained.
