And a driving mechanism is hinged to the bottom side of the side mold. The hinged seats are arranged on the two sides of the bottom of the bottom die, the side dies are hinged to the bottom die through the cantilevers, and the hinged seats are hung on the bottom face of the bottom die, so that muddy water is not prone to immersing into the hinged seats, the service life of the die is prolonged, and the maintenance cost is reduced.

The utility model relates to the technical field of greening, in particular to a basement roof greening heap slope structure. Comprising a top plate, a waterproof protection layer, a plurality of EPS plates, non-woven fabric, planting soil and green plants are sequentially arranged on the top plate from bottom to top, a first protrusion is arranged at the lower end of the EPS plate on the uppermost layer, a second groove is formed in the upper end of the EPS plate on the lowermost layer, a first groove is formed in the upper end of the EPS plate on the middle layer, and a second protrusion is arranged at the lower end of the EPS plate on the middle layer. The structure of the first protrusion is matched with the structure of the first groove, and the structure of the second protrusion is matched with the structure of the second groove. Compared with the prior art, the EPS plate and the non-woven fabric are additionally arranged on the basement top plate, so that soil piling modeling is carried out after the terrain height is increased, the vertical height of a site can be effectively increased under the condition that loads are not increased, different piling slope heights can be built, and the landscape effect is met. And the multiple EPS plates are modularly spliced through concave-convex structures, so that installation is convenient, and sliding is not prone to occurring.

The utility model relates to the technical field of sofas, and provides an intelligent sofa with a lifting function, which comprises a sofa body, placing components arranged at two ends of the sofa body and used for placing sundries, and lifting components arranged at the lower ends of the two placing components and used for lifting the sofa body. A transmission assembly is arranged at the bottom end of each lifting assembly and used for transmitting the lifting assembly, a leg placing assembly is arranged at the bottom end of the front side of the sofa body and used for placing legs of a user, and the placing assembly comprises armrests fixedly connected to the outer wall of the top end of the front side of the sofa body; a drawer is slidably connected to the inner wall of the front end of the armrest, the lifting assembly comprises a limiting top frame fixedly connected to the outer wall of the bottom end of the sofa body, top end sliding rails are arranged at the two ends of the rear side of the limiting top frame in a penetrating mode, and scissor supports are arranged on the inner sides of the two top end sliding rails; the height of the sofa can be conveniently adjusted according to the requirements of users with different heights.

The application relates to a vehicle frame structure in the technical field of vehicle frames, which comprises a longitudinal beam assembly, a mounting seat assembly and a cross beam assembly, the longitudinal beam assembly comprises two longitudinally arranged longitudinal beams, the mounting seat assembly is fixedly connected with the lower flange plates of the longitudinal beams, and the cross beam assembly is fixedly connected with the longitudinal beams and the mounting seat assembly.
