The invention relates to an automatic direction-changing lifting device for a vehicle. The automatic direction-changing lifting device comprises a base, a rotating platform, a lifting platform, lead screws, a lift driving motor, a rotary driving motor, a revolution support and lead screw nuts, wherein the rotating platform, the lifting platform and the base are arranged horizontally in sequence from top to bottom, and gaps are reserved among the rotating platform, the lifting platform and the base; the rotating platform is positioned on the top of the entire device; the base is positioned at the bottom of the entire device; the lead screw nuts are arranged on the lifting platform; the bottom ends of the lead screws pass through the lifting platform, and are arranged on the base; the lift driving motor is arranged on the base; the bottom ends of the lead screws are connected with the lift driving motor; the rotary driving motor is arranged on the lifting platform; the revolving support is arranged between the rotation platform and the lifting platform, and is connected with the rotating platform and the lifting platform; the revolving support is further connected with the rotary driving motor. The automatic direction-changing lifting device has the beneficial effects of simple structure, convenience in operation and stability in running. By adopting the automatic direction-changing lifting device, a vehicle can be reversed parked into a garage without labor force, the vehicle can be parked and driven away conveniently, and the vehicle parking efficiency is increased.

The invention discloses a wall surface decoration installing structure, which comprises at least one decoration unit and a connecting device for arranging the decoration unit on a wall surface, wherein each decoration unit comprises a first section, a second section and a decoration material; the first section comprises a first side edge and a buckling piece arranged on the first side edge in a protruding way; the second section comprises a second side edge matched with the first side edge, and an accommodating groove which is formed on the second side edge and is buckled with the buckling piece; and the decoration material is clamped between the first section and the second section via the clamping of the buckling piece and the accommodating groove after being wrapped on the surface of the first section. According to the wall surface decoration installing structure, the decoration material is arranged by buckling the second section on the first section, so that convenience is brought to installation and adjustment.

The invention discloses an upper bracket device for preventing a cylinder body from rolling deformation. The upper bracket device comprises a bracket device support body. A roller support A and a roller support C are symmetrically arranged on the upper side of a base of the bracket device support body. A roller support B is arranged on the inner side of the roller support A. An upper roller and alower roller are arranged on the roller support A, the roller support C and the roller support B. The two ends of the upper roller and the two ends of the lower roller are arranged on the roller support A, the roller support C and the roller support B. The rollers are driven by a motor. A stand column is arranged on the top of the roller support C. A transmission rod is arranged at the center in the stand column. A hydraulic oil cylinder is arranged at the bottom end of the transmission rod. A bracket close to the top and on one side of the stand column is driven by the hydraulic oil cylinderto rise or fall. The upper bracket device is reasonable in design, the rolled cylinder body is supported by the bracket when the cylinder body is rolled, and the cylinder body is prevented from deformation.

The invention discloses air purification and disinfection equipment capable of generating uniform high-concentration plasma. The equipment mainly comprises a housing (1), a fan (2), a plasma generator (3) and a boosting power supply (4), wherein the plasma generator (3) consists of a plurality of cylindrical plasma fundamental reaction units (30); the cylindrical plasma fundamental reaction units (30) comprise positive electrodes and negative electrodes; the positive electrodes are discharge electrode wires (310); the negative electrodes are hollow metallic circular tubes (320); the metallic circular tubes take the discharge electrode wires as center shafts; end covers (330) made of non-conducting insulation materials are arranged at the two ends of each metallic circular tube (320); and a plurality of hollow through holes (B) are formed in the two end covers (330). According to the equipment, air entering an air disinfection machine can be excited to be the uniform high-concentration plasma, so that indoor air can be disinfected, sterilized, dedusted and deodorized rapidly and effectively.
