摘要： A safety pin locking device for workpiece turnover includes a safety pin, a triangular lock plate, an elastic positioning pin, and a lockset. The safety pin is configured to be inserted into a base and an overturnable workpiece to lock an angle of the overturnable workpiece relative to the base. A first corner end of the triangular lock plate is connected to an axial surface of the safety pin by a fastener, and the triangular lock plate can rotate around the fastener. The elastic positioning pin is mounted at a second corner end of the triangular lock plate and is configured to be inserted into positioning counterbores at two different positions on the axial surface of the safety pin to limit a position of the triangular lock plate. The lockset is mounted at a third corner end of the triangular lock plate.

摘要： A tilting truck bed includes a bed body configured to load materials, lifting supports, shock absorber supports and a shock-absorbing pad assembly. The bed body includes a first bottom plate, a front plate, a tail plate, a left side plate, and a right side plate that are welded to upper edges of the first bottom plate. The lifting supports are symmetrically mounted on the tail plate and hinged to the frame to realize the tipping of the bed body. The shock absorber supports are symmetrically mounted on both sides of the front part of the first bottom plate, wherein the shock absorber support includes a shock absorber support main body and a gap adjusting device.
