The invention discloses a pile-breaking-free mechanical connection method between a reinforced concrete square pile and a bearing platform, and the connection method comprises the following steps: manufacturing a steel reinforcement framework, connecting the steel reinforcement framework with a pile top end plate through a steel sleeve, and then pouring a concrete pile body to form the reinforced concrete square pile; the reinforced concrete square pile is subjected to pile sinking construction; and the pile top end plate is dismantled, and the bearing platform anchoring rib and the reinforced concrete square pile are mechanically connected through the steel sleeve. According to the pile-breaking-free mechanical connection method between the reinforced concrete square pile and the bearing platform, mechanical connection between the reinforced concrete square pile and the bearing platform can be achieved without mechanical breaking of the pile head of the reinforced concrete square pile, field welding work is avoided, construction is convenient and fast, and the method is more economical and reasonable.

The application relates to a concrete building steel plate reinforcing structure and a construction method, and belongs to the field of building construction. The concrete building steel plate reinforcing structure comprises a first fastening plate, one side of the first fastening plate is provided with a second fastening plate connected with the first fastening plate, the first fastening plate and the second fastening plate are matched to reinforce a concrete column, one side of the first fastening plate close to the second fastening plate is fixedly connected with a first connecting rod, one end of the first connecting rod away from the first fastening plate is arranged to pass through the second fastening plate, one side of the second fastening plate close to the first fastening plate is fixedly connected with a second connecting rod, and one end of the second connecting rod away from the second fastening plate is arranged to pass through the first fastening plate. The application has the effect that a reinforcing part for reinforcing a concrete column is stably connected with the concrete column.

This invention relates to the field of connector technology and discloses a self-coupling connector, including a main connector. A lower housing is fixedly disposed on one side of the main connector, and an upper housing is disposed at the upper end of the lower housing. Four sets of first bolts are threadedly connected to the upper and lower housings around their perimeters. A mating pin is fixedly disposed inside the main connector. A positioning component is disposed inside the lower and upper housings, and a shielding component is disposed inside the lower and upper housings near the positioning component. The positioning component includes a mating cavity formed in the lower and upper housings, and a sleeve is fixedly disposed on one inner wall of the mating cavity. The self-coupling connector of this invention, through overall cooperation, allows the locking block to automatically engage inside the slot and shield the mating pin end face in the sleeve, preventing contamination when not mated.

This utility model discloses a conductive hinge and a photovoltaic folding panel, relating to the field of solar energy device technology. The conductive hinge includes a hinge body and an electrical connection module. The hinge body includes a first hinge piece and a second hinge piece rotatably connected, with the first and second hinge pieces respectively connected to two photovoltaic panels. The electrical connection module includes a soft rubber sleeve and a conductive wire disposed within the soft rubber sleeve. One end of the soft rubber sleeve is connected to one photovoltaic panel via the first hinge piece, and the opposite end of the soft rubber sleeve is connected to the other photovoltaic panel via the second hinge piece. The conductive wire is electrically connected to the two photovoltaic panels connected to the hinge body. The technical solution provided by this utility model simplifies the usage steps of the photovoltaic folding panel.

This invention relates to a standard device for extending the liquid circuit for easy extravehicular operation by astronauts, comprising an extension adapter and an extension housing. The extension adapter is the passive end, installed on the spacecraft cabin and launched with the spacecraft. The extension housing is the active end, installed by the astronaut after exiting the spacecraft and attached to the extension adapter. The extension adapter and the extension housing are connected mechanically, electrically, and through liquid circuits. These interfaces are all standard interfaces, and the connection method is independent of the type of liquid circuit equipment installed inside the extension housing, such as pump assemblies, valve assemblies, and working fluid replenishment assemblies. The standard device for extending the liquid circuit of this invention features standardized interface design, adaptability for astronauts operating while wearing extravehicular spacesuits, no need for auxiliary tools, simple operation, and short operation time, and can meet the requirements for pressurized, leak-free operation of the extravehicular liquid circuit.
