The utility model relates to the technical field of doors and windows, in particular to a sliding-assisting buffering closer with a locking point, which is characterized in that one side of a fixed seat is fixedly connected with a guide post, the top of the fixed seat is movably connected with a steel ball, one side of the fixed seat is movably connected with a sliding-assisting piece main body, and the joint of the sliding-assisting piece main body and the fixed seat is fixedly connected with a gasket; and a hexagon nut is movably connected to the interior of the fixed seat through a thread. According to the sliding-assisting buffering closer with the locking point, the sliding-assisting piece is additionally arranged and installed on one side of the clamping groove, so that a door leaf slides more smoothly, the guide column is designed on the fixed seat, the guide groove is designed in the movable seat, when the door leaf is closed, the guide column is matched with the guide groove, and the stable and anti-loosening effects are achieved; and the movable seat and the fixed seat can be locked together quickly and simply, so that the movable seat and the fixed seat are kept in a relatively stable state without being subjected to certain external force, and subsequent operation of the Pemperor door is facilitated.

The utility model relates to a wardrobe folding wheel, which is used for installing a wardrobe door and is characterized in that a pulley seat is fixedly arranged on a vertical column at the top of a pulley arm, two main pulleys are horizontally arranged at the top of the front surface of the pulley seat, a fixed seat is fixedly arranged on the front surface of the pulley seat and below the main pulleys through screws, and an auxiliary pulley is arranged on the fixed seat. And the main pulley and the auxiliary pulley are vertically opposite up and down and form an inverted delta-shaped layout. The sliding door has the advantages of being simple in structure, low in manufacturing cost, small in noise, smooth in sliding and capable of preventing the sliding door from being derailed accidentally with glue.

The tunnel construction rapid escape device comprises a pipe body, the pipe wall of the pipe body is a three-layer composite structure, and the pipe wall is sequentially provided with a wear-resistant layer, an intermediate layer and a protective outer layer from inside to outside; the pipe wall is uniformly distributed with a honeycomb hollow structure, and an axially extending track is fixedly arranged on the inner wall of the pipe body; the three-layer composite structure composed of the wear-resistant layer, the intermediate layer and the protective outer layer from inside to outside is combined with the honeycomb hollow design, the overall weight is greatly reduced, the compression resistance, bending resistance and impact resistance are provided, and the rockfall, wear, corrosion and humid environment are effectively resisted; adjacent pipe bodies are connected through flanges through plug-in interfaces and adjacent tracks, modular rapid assembly is realized, the channel is air-tight, water-tight and the track has high straightness, and the construction efficiency is high.
