This invention discloses a semi-automatic sealing ring assembly machine, belonging to the technical field of sealing ring assembly equipment, and solves the problems of low efficiency and poor consistency in existing manual assembly. The assembly machine includes a worktable, an expansion unit, a transfer unit, and an elastic pressure-distributing component. The drive mechanism of the expansion unit drives multiple support rods to move radially synchronously, realizing the switching of the sealing ring between the loading and expansion positions. The carrier seat of the transfer unit moves axially through a lifting drive component. The elastic pressure-distributing component is mounted on the carrier seat and includes two elastic clamps spaced apart along the axial direction of the sealing ring. The elastic clamps can open and close axially and, together with the support rods, provide radial pressure support for the sealing ring at the expansion position. This invention, through its pressure-distributing support structure, adaptive linkage of the elastic clamps, and synchronous drive of the expansion unit, achieves semi-automatic and efficient assembly of the sealing ring, regulates contact force, stably releases elastic potential energy, avoids assembly jamming, deformation, and ejection, and improves assembly accuracy and sealing reliability.

This utility model discloses a color-reflective high-strength PVC sheet, relating to the field of PVC sheets. It includes a PVC substrate layer, with a color-reflective composite layer for reflecting colors disposed on one side of the PVC substrate layer. The color-reflective composite layer comprises a primer layer, a colored pigment layer, and a reflective layer stacked sequentially. A reinforcing layer for increasing the strength of the PVC substrate layer is disposed on the other side of the PVC substrate layer. This color-reflective high-strength PVC sheet, by incorporating the color-reflective composite layer composed of a primer layer, a colored pigment layer, and a reflective layer, allows for the formulation of a rich variety of colors to meet diverse decorative design needs. It enhances light reflection performance, making it suitable for applications requiring light reflection. Simultaneously, the reinforcing layer, while ensuring lightweight construction, enhances the sheet's tensile, bending, and impact resistance, reduces surface wear, and extends its service life, enabling it to adapt to more complex usage environments.
