The utility model discloses a burn -through ware of prolonging busbar service life belongs to burn -through ware technical field, including wiring copper bar, the inside of one side of wiring copper bar is equipped with a plurality of assembling screw holes, and the middle position of wiring copper bar is provided with the bending part, and the inside symmetry of wiring copper bar is equipped with busbar screw hole one end far from assembling screw hole, the utility model discloses the bending of wiring copper bar is formed bending part according to the required angle, then according to the running direction of burn -through ware busbar, the inside symmetry of wiring copper bar is equipped with busbar screw hole according to the required angle, and the edge of busbar screw hole is polished and is handled regularly, and the wear and tear of busbar is reduced, to avoid the burn -through ware busbar in the process of using the shearing force of bearing to the greatest extent, prolongs the service life of burn -through ware busbar, prevents the damage situation of busbar because of copper wire broken strand appearance damage, improves the use period of busbar, reduces the workload of replacing busbar, can also save production cost simultaneously.

The utility model discloses a kind of anti-deviation steel strip rolling device, it is related to steel strip rolling technical field.The utility model includes bottom box, the bottom box top side is fixedly connected with rolling frame, the rolling frame inside is fixedly connected with bottom roll, the bottom roll rear side is fixedly connected with drive box, the rolling frame inside is threadedly connected with adjusting lever, the adjusting lever bottom is movably connected with top roll by bearing.The utility model is designed by anti-deviation roller of conical body shape, when steel strip deviates, its inclined plane is contacted with steel strip edge, because the linear velocity gradient of roll surface changes along axial direction and forms asymmetric lateral friction force, restoring force pointing to rolling center is generated, drive steel strip automatic return normality.Anti-deviation roller is driven by second driving motor, keeps same direction rotation, avoids shear stress caused by reverse rotation, reduces steel strip edge scratch, indentation and edge curl risk, significantly improves rolling precision and product quality.

The application provides a racing car suspension structure, which comprises a left stand, a right stand, a left suspension and a right suspension; a connecting assembly is installed at the center of a frame; the left suspension comprises a left upper transverse arm and a left lower transverse arm; the right suspension comprises a right upper transverse arm and a right lower transverse arm; one end of the left upper transverse arm and the left lower transverse arm is rotatably connected with the upper end and the lower end of the left stand respectively; one end of the right upper transverse arm and the right lower transverse arm is rotatably connected with the upper end of the right stand respectively; the other end of the left upper transverse arm and the right upper transverse arm is rotatably connected with the upper end of the connecting assembly respectively; the other end of the left lower transverse arm and the right lower transverse arm is rotatably connected with the lower end of the connecting assembly respectively; the left upper transverse arm and the right upper transverse arm are axially symmetrical relative to the connecting assembly; the left lower transverse arm and the right lower transverse arm are centrally symmetrical relative to the connecting assembly. The application can maximize the utilization of the lateral arrangement space of the vehicle by the length of all the transverse arms, change the wheel track and the positioning parameters of the wheels within the acceptable limited range, and improve the steering stability of the vehicle.
