The utility model discloses an adjustable supporting arm structure for an electric tricycle, and relates to the technical field of tricycle supporting arms, the adjustable supporting arm structure comprises a fixing arm, the outer wall of the fixing arm is fixedly connected with a connecting structure, the inner wall of the connecting structure is slidably connected with a fixing bolt, and the outer wall of the fixing bolt is in threaded connection with a locking nut. A telescopic cavity is slidably connected to the outer wall of the fixed arm, a telescopic arm is slidably connected to the outer wall of the telescopic cavity, and an adjusting structure is fixedly connected to the outer wall of the telescopic arm. And long-distance adjustment depends on sliding adjustment of the telescopic arm and the telescopic cavity, and angle adjustment depends on cooperation of various structures, so that different vehicle types can be adapted, the assembly problem is effectively solved, the assembly speed is increased, the rework rate is reduced, and the production process is optimized.

This utility model discloses a hardware riveting mechanism, comprising: a frame; a mold base, which is movably mounted on the frame, with riveting heads and several guide plates respectively provided at its lower end, wherein there are at least two riveting heads, and the guide plates are arranged at intervals along the same horizontal direction between the two riveting heads, with V-shaped guide grooves recessed at the lower end of the guide plates; a cutting component, which is mounted on the mold base and located on opposite sides of the two riveting heads, for cutting the wire; a driving component, which is mounted on the frame, for driving the riveting heads to move up and down reciprocally; and an adjusting component, which is mounted on the mold base and connected to one of the guide plates, for driving the corresponding guide plate to adjust its displacement longitudinally. This mechanism integrates riveting, wire guiding, cutting, metal sheet bending, and wire length adjustment functions into one unit, reducing process changeover time, significantly improving processing efficiency, and reducing errors during workpiece transfer.

The utility model discloses a double -sided display board component, including at least one first display panel component and at least one second display panel component, the first display panel component and second display panel component between each other detachable connection becomes a linear display panel component. The double -sided display board component its application in double -sided display board, can adjust the use length of double -sided display board, expands the application scope of double -sided display board.

This utility model relates to the technical field of flexible copper busbar connections, and particularly to an adjustable-length safety charging pile battery flexible connection device. It includes a protective frame, a first copper busbar, and a second copper busbar. Connecting terminals are fixedly connected to the opposite sides of both the first and second copper busbars. An adjustment component is fixedly connected to the inner bottom wall of the protective frame, and a drive component is fixedly connected to the front of the protective frame. This adjustable-length safety charging pile battery flexible connection device, through the coordinated arrangement of the adjustment component, drive component, and locking component, allows for the adjustment of the distance between the movable copper busbar and the positioning copper busbar using a right-angle bracket, thereby increasing or decreasing the length of the first copper busbar. This enables flexible adjustment of the flexible connection length when installing charging pile batteries of different models. Furthermore, the spring force presses the locking block tightly into the locking hole on the front of the right-angle bracket, ensuring that the position of the movable copper busbar does not shift after adjustment, resulting in higher stability.
