The utility model relates to the technical field of indoor decoration, and provides a fabricated decoration wallboard which comprises boards, connecting pieces and a mounting structure frame. The mounting structure frame comprises a fixed frame and a connecting frame which are fixedly connected. The connecting piece is installed between a plate and a blank wall and comprises angle iron, an expansion bolt and a hanging piece. The angle iron is fixed on a blank wall through expansion bolts, the pendant is mounted at the upper end of the angle iron, the fixing frame is detachably connected with the pendant, and the connecting frame is arranged on one side of the fixing frame. Magnetic sheets and raised lines are arranged on the back side of the plate, the magnetic sheets are adsorbed on the connecting frame, and the raised lines support the connecting frame to share the weight of the plate. Through magnetic connection and a raised line supporting structure, rapid installation and replacement of the wallboard are achieved, meanwhile, the position of the hanging piece is adjusted to adapt to the uneven surface of a blank wall, and the overall flatness of the wall face is guaranteed.

This utility model discloses a production and processing equipment for diamond mesh security screens, belonging to the field of screen processing technology. It includes a workbench with mounting grooves on both sides of its upper surface. Each mounting groove is rotatably connected to a threaded screw via bearings. Each threaded screw has a mounting seat threaded onto its surface. A clamping plate is fixedly connected to the upper end of each mounting seat. Each clamping plate has sliding grooves at both ends, and sliding rods are movably connected inside the sliding grooves. This utility model, by setting up clamping plates, ensures the window frame's stable position and precise positioning during processing, improving the equipment's versatility and practicality. By setting up positioning components, the device can flexibly meet the positioning needs of different corners of the security screen, achieving effective positioning of each corner of the security screen, ensuring the security screen remains stable during processing, and improving the overall quality and aesthetics of the product.

The application discloses an office partition steel structure frame, which comprises a first partition plate, a sliding groove is formed in the right end surface of the first partition plate, a sliding plate is slidably connected in the sliding groove, sliding grooves are symmetrically formed in the sliding groove, sliding plates which are matched with the sliding grooves are symmetrically and fixedly connected to the outer side of the sliding plate, a plurality of insertion grooves are formed in the inner wall of the sliding groove, a cavity is formed in the sliding plate, two sliding rods are symmetrically and slidably connected in the cavity, springs are fixedly connected between the two sliding rods, and moving grooves which are communicated with the cavity are formed in the two opposite sliding plates. The application realizes flexible adjustment of the partition angle, the second partition plate can freely rotate around the shaft rod through the cooperation of the sliding plate and the rotating groove, the limitation of the traditional ninety-degree right-angle partition is broken, the demand of special-shaped building space and diversified office layout is met, and the problem of insufficient adaptability of the existing rigid connection mode is solved.
