The invention relates to a decoration installation structure, and provides a decoration installation structure for a greening wall aiming at the problem of reduction of stability of an installation structure caused by gravity center shift due to nonuniformity of plant growth. The structure enables plants to be rotated and makes the plants receive uniform illumination; and the technical scheme is that the structure comprises a base seat and a plurality of supporting units, each supporting unit comprises a plurality of parallel screw rods, two adjacent screw rods are connected through a connecting rod, lifting supporting members are slidably connected to the interior of each supporting unit, each supporting member is provided with a sliding member clamped on the screw rods for sliding, connecting columns are connected between two adjacent supporting members, the base seat is provided with a driving device used for driving supporting members located at the bottom to be lifted, and a maximum stroke of the driving device is greater than a screw pitch of the screw rods. According to the structure provided by the invention, in the lifting process of the supporting members, the plants aredriven to rotate, so that the plants receive uniform illumination, the plants grow uniformly, gravity center shift of the plants is reduced, gravity center shift of the installation structure is reduced, and stability of the installation structure is improved.

The invention discloses an inertial-impact-preventing liquid tank provided with cylindrical spiral tubes inside. At least one group of cylindrical spiral tubes are arranged inside the liquid tank, a liquid tank upper liquid communication position is arranged between tops of the spiral tubes and the upper inner wall of the liquid tank, and a liquid tank lower liquid communication position is arranged between bottoms of the spiral tubes and the lower inner wall of the liquid tank, so that a liquid is contained inside the spiral tubes and internal gaps of the liquid tank; tube sections of the spiral tubes are round, rectangular, triangular, hexagonal or irregular, the multiple groups of spiral tubes are horizontally and closely arranged and fixed inside the liquid tank, and the spiral tube on the outmost circle is fixed on the inner side wall of the liquid tank. According to the liquid tank, the position of the center of gravity of the liquid is stabilized by the aid of a spiral structure, the liquid inside the tank can only move along the spiral tubes due to constraint of the spiral tubes in the movement process of the liquid tank, the inertial impact of the liquid is prevented, and the shift of the center of gravity is reduced, so that movement stability and safety of means of transport are improved.

The invention discloses an electronic device which comprises a fixed support, a first telescopic support, a second telescopic support and a flexible screen, wherein the first telescopic support and the second telescopic support are symmetrically arranged relative to the fixed support; the first end of the flexible screen is connected with the first telescopic support; the second end of the flexible screen is connected with the second telescopic support; and the first telescopic support and the second telescopic support can do telescopic motion relative to the fixed support at the same time so that the flexible screen can be switched between a retracted state and an unfolded state. According to the electronic device provided by the embodiment of the invention, the holding effect of the electronic device can be improved, and the holding comfort of a user on the electronic device is improved.

The invention relates to the technical field of storage equipment, and discloses a high-density storage storage device, comprising a shelf and a handling tower. The lower end of the frame has no bottom, and the moving support plate can extend into the interior of the inner box. The high-density storage storage device is directly stacked in the storage compartment of the shelf, and the goods are transported in a single row. Compared with the overall handling of the stacked goods, the requirements for the width of the reserved passage for the goods are greatly reduced. The floor space of the aisle is reduced, the goods are placed in a single row on the storage chassis for transportation, and the goods are also lifted in rows when they are lifted. The requirements for power equipment are lower. On the other hand, the mass of a single lift is less, the center of gravity shift caused by pushing into the rack is smaller, and the requirements for equipment counterweight are lower.
