The utility model belongs to the technical field of medical instruments, and particularly discloses a bone defect transplantation support. The bone defect transplantation stent comprises an outer tube body and an inner supporting piece, and the outer tube body extends from one end to the other end; the inner supporting piece is arranged in the outer pipe body and comprises an inner pipe body and a first supporting plate, the extending direction of the inner pipe body is consistent with that of the outer pipe body, an annular containing cavity is formed between the outer wall of the inner pipe body and the inner wall of the outer pipe body, and the first supporting plate is arranged in the containing cavity and connected with the inner pipe body. An included angle is formed between the extending direction of the first supporting plate and the extending direction of the inner pipe body. According to the utility model, the graft can be reliably fixed, and the filling amount of the graft is reduced.

The application discloses a method for saving activated carbon and porcelain rings in a lower head of a converter in production of calcium carbide method polyvinyl chloride, and belongs to the technical field of polyvinyl chloride production, and comprises the following steps: S1, horizontally welding a support frame in a straight cylinder section of the lower head of the converter; S2, laying a steel grating on the support frame, laying a steel wire mesh on the steel grating, and fixing the steel wire mesh to the steel grating by iron wires; the support frame is horizontally welded in the straight cylinder section of the lower head of the converter, the steel grating is laid on the support frame, the steel wire mesh is laid on the steel grating, and the steel wire mesh is fixed to the steel grating by the iron wires; the glass silk cloth I is laid on the steel wire mesh through edge pressing, the lower head gasket is placed on the pressing surface of the lower head, the activated carbon is laid on the glass silk cloth I, the glass silk cloth II is laid on the activated carbon, the filling of the phi 50 porcelain ring and the phi 25 porcelain ring is cancelled, the filling amount of the activated carbon in the lower head of each converter is effectively reduced, the filling weight of the lower head of the converter is reduced, and the lifting and installation risk of the lower head of the converter is reduced.

The utility model discloses a photovoltaic power adapter structure of a light stacking system. The photovoltaic power adapter structure comprises a plastic back plate, a control plate, a power plate, an aluminum alloy heat dissipation shell, a plastic bottom cover, a plastic upper cover, an output power cable and an input power cable. The whole aluminum alloy heat dissipation shell is in a groove shape, the plastic back plate, the plastic upper cover and the plastic bottom cover are all installed on the aluminum alloy heat dissipation shell and form a containing space, the control plate and the power plate are arranged in the containing space, the power plate is an aluminum substrate, and the power plate is fixed to the aluminum alloy heat dissipation shell in a screw fastening mode. The smooth back face of the power board is tightly attached to the aluminum alloy heat dissipation shell, the power board is electrically connected with the control board, the output power cable and the input power cable are arranged on the plastic bottom cover, and a sponge sealing ring for protection is arranged at the position of a dial switch of the control board. The whole structure is simple, only one set of plastic mold and one set of profile mold are needed, and the earlier-stage investment cost can be saved.
