The utility model discloses a compaction steel wire rope for a load elevator, and relates to the technical field of elevator ropes. According to the compacted steel wire rope for the load elevator, the internal strength of the steel wire rope can be effectively improved by utilizing the characteristics of extremely high hardness and flexibility of the titanium alloy twisted rope, and the outer side of the outer-layer strand is effectively isolated and protected by utilizing the characteristics of excellent mechanical strength, wear resistance and better corrosion resistance of the nylon material of the protective functional layer; the outer side of the protection function layer is waterproof through the damp-proof function layer, meanwhile, moisture is absorbed by the drying agent, damp-proof of the outer side of the steel wire rope is achieved, and the corrosion resistance of the steel wire rope is improved by utilizing the characteristics of good elasticity and acid and alkali resistance of a rubber material of the corrosion-resistant function layer and the excellent corrosion resistance of aluminum oxide aluminum foil; the strength of the wear-resistant functional layer is increased through the thin steel wires, and the outer side of the corrosion-resistant functional layer is protected by utilizing the characteristics of high strength and low density of a polyethylene fiber material of the wear-resistant functional layer.

This application relates to a stacked interlocking semiconductor packaging structure, comprising: a substrate, a base plate, two chips, a packaging layer, and a protective shell; the substrate is disposed on the top surface of the base plate, and two chips are disposed on the substrate, with the packaging layer encapsulating the chips and the substrate; the protective shell is disposed on the top surface of the base plate and surrounds the sidewalls of the packaging layer; the protective shell includes: two or more stacked rings, each ring having a limiting groove on its inner sidewall, and the packaging layer having multiple limiting protrusions on its sidewalls, the limiting protrusions matching the limiting grooves for embedding within the limiting grooves. The protective shell surrounding the packaging layer effectively isolates and protects the packaging layer, preventing damage caused by direct exposure of the packaging layer's sidewalls to the outside. This application utilizes a stacked, interlocking ring structure to reliably complete the packaging process of microelectronic components or semiconductor devices; the overall structure is simple and easy to manufacture; it has significant advantages in terms of process speed and cost.

The utility model discloses an elevator maintenance safety maintenance device which comprises L-shaped supporting plates, the number of the supporting plates is two, the two supporting plates are symmetrically arranged, a supporting mechanism is installed on the two supporting plates, a protection mechanism is installed on the supporting mechanism, and the protection mechanism is connected with the supporting mechanism. The supporting mechanism comprises a screw rod, a rotating ring, a fixing cylinder and two supporting seats, one end face of each supporting seat is fixedly connected with the side face of the corresponding supporting plate, and the other end face of each supporting seat is fixedly connected with one end of the screw rod and one end of the fixing cylinder. The safety maintenance device for elevator maintenance cannot topple over when subjected to external force, an elevator opening can be effectively isolated and protected, and safety accidents caused by toppling over of the protection plate during elevator maintenance are prevented.
