The utility model relates to the technical field of elevator construction protection, and discloses a detachable elevator protection turning plate for shaft construction, which comprises a main body component and a lift car top cover, a turning plate is arranged on the lift car top cover, a hinge is movably connected onto the turning plate, the turning plate is in bolt connection with the hinge, a handle is arranged on the turning plate, and the handle is connected with the lift car top cover. A rubber pad is fixed on the turnover plate; a dovetail groove is formed in the lift car top cover, and a bolt is arranged in the dovetail groove; the hinge is connected with the turnover plate through three bolts; and the hinge is connected with the turnover plate through three bolts. The detachable protection turning plate has the advantages that the detachable protection turning plate is designed, the gap between the lift car and the well wall is effectively filled, the angle of the turning plate can be properly adjusted to adapt to the gaps with different widths, and therefore the situation that objects and people fall from high altitudes is avoided, and safety of operators is guaranteed.

The utility model relates to the technical field of electronic connecting wires, in particular to an anti-breaking electronic connecting wire, which comprises a plurality of wire bodies, one end of each wire body is mounted on a wiring port, the surface of the wiring port is provided with a wiring groove, a rubber plug is inserted into the wiring groove and sleeved on the wire body, and the rubber plug is inserted into the wiring groove. One end of the rubber plug block is fixed on the surface of the connecting sheet, the connecting sheet is mounted on one side of the wiring port, a silica gel extension block is fixed on the surface of the connecting sheet, and the silica gel extension block sleeves the wire body; the beneficial effects are that the rubber plug block is plugged in the wiring groove, and the rubber plug block is sleeved on the wire body. When the rubber plug block is plugged into the wiring groove, a gap between the wire body and the wiring groove can be tightly filled, and the wire body is stably fixed in the wiring groove, so that the wire body is prevented from swinging randomly for a long time in the wiring groove, and the phenomenon that the wire body is damaged due to bending in the wiring groove is effectively prevented.

The application provides a carbon-carbon composite material defect repairing liquid, a preparation method thereof and a defect repairing method of a carbon-carbon composite material component, and the carbon-carbon composite material defect repairing liquid comprises the following components in percentage by mass: 0.05%-0.2% of a silane coupling agent, 5%-14% of an organic solvent, 10%-25% of graphite powder, 60%-80% of phenolic resin and 0.5%-2% of polyvinylpyrrolidone, wherein the mesh number of the graphite powder is 200-1000, the solid content of the phenolic resin is 80wt%-85wt%, and the residual carbon content of the phenolic resin is 60wt%-75wt%. The carbon-carbon composite material defect repairing liquid has a good defect repairing effect on the carbon-carbon composite material component, and has the advantages of simple operation, short cycle and low cost.
