The application discloses a cord fabric unwinding and wrinkle removing device and a production method of an unwinding roller, and belongs to the technical field of cord fabric manufacturing. The unwinding and wrinkle removing device comprises an unwinding roller, a main hot moistening positioning roller and an auxiliary hot moistening pressing roller. Cord fabric on a cord fabric winding disc sequentially passes through the unwinding roller, the main hot moistening positioning roller and the auxiliary hot moistening pressing roller. The unwinding roller is used to apply a force to the cord fabric, so that the cord fabric is stretched along the width direction of the cord fabric. The main hot moistening positioning roller is used to moisten and fix the unwound cord fabric. The auxiliary hot moistening pressing roller is used to assist in moistening the cord fabric. The unwinding and wrinkle removing device integrates unwinding, setting and moistening. When the cord fabric is unwound, the unwound state can be fixed, and the cord fabric surface can be smoothed and wrinkle-free in time through moistening, so that the cord fabric is prevented from being stained with glue due to wrinkles.

The utility model discloses a folding magnetic attraction keyboard relates to the technical field of folding keyboard, including first keyboard board and second keyboard board, and the top surface one side of first keyboard board is equipped with silica gel pad, and the other side of second keyboard board is equipped with the connecting plate, and the connecting place of first keyboard board and second keyboard board is equipped with the folding subassembly, the utility model discloses through the cooperation between angle chain, first hinged plate, second hinged plate and sliding slot, can realize the smooth folding and unfolding of first keyboard board and second keyboard board, and can complete the folding and unfolding without complex operation, through the support of first hinged plate, second hinged plate, the structural stability of keyboard unfolding has been strengthened, avoids the occurrence of shaking in use, through the cooperation of positioning post and positioning slot, contact and connecting slot, can make the connecting plate with second keyboard board accurate butt joint, both guaranteed the stability of connection, realized the stable electric connection of both, ensured display lamp, touchpad and other components and keyboard main body collaborative work.

The utility model discloses a portable anti-toppling foldable ladder which comprises two rod bodies, a protection assembly is arranged on one side of each rod body, a folding assembly is arranged between the two rod bodies, and the problems that an existing ladder is insufficient in stability and inconvenient to store are effectively solved through mutual matching of the protection assemblies and the folding assemblies. The protection assembly adopts a meshing self-locking structure of a ratchet wheel, a pawl and an extension spring, automatic limiting can be achieved when the ladder is unfolded, the toppling risk caused by external force or operation shaking is prevented, the use safety is remarkably improved, meanwhile, the adjustable design of a first movable plate and a second movable plate is matched with limiting screw holes, the supporting stability is further enhanced, and the safety of the ladder is improved. The folding assembly is connected with the folding plate in a hinged mode through the rotating rod, the ladder is rapidly folded to be in an attached state, the occupied space is greatly reduced, carrying and storage are convenient, unfolding and folding operation is simplified through cooperation of a limiting bolt and an adjusting opening, and it is ensured that the folding process is smooth and the ladder is firm and reliable after being unfolded.

This invention discloses a mechanical muscle device for an automotive collision dummy, relating to the field of automotive safety testing technology. It includes an end cap, a ball screw with both positive and negative threads, a screw nut, a shell flap, an active connecting rod, a pin, and a buffer structure unit. The buffer structure unit is mounted on the shell flap, and its lattice energy-absorbing core layer adopts one of the following: a beetle-inspired curved rib lattice structure, a chiral nested hexagonal structure, or a hexagonal FBCC structure. Through the mechanical coordinated drive of the ball screw with both positive and negative threads and the X-type scissor unit, the rotational motion of the servo motor is precisely converted into the radial expansion and axial contraction of the shell flap, accurately simulating the active tension and passive stretching of muscles during a collision. Compared to pneumatic or hydraulic solutions, this all-mechanical structure has the advantages of rapid response, high control precision, and no leakage risk, avoiding the instability of fluid components under high-speed impact, and significantly improving the bio-simulation of the dummy and the reliability of test data.
