4results about How to "Avoid Axial Misalignment" patented technology

This utility model relates to an advertising machine with a rotating structure, belonging to the field of advertising machine technology. The advertising machine with a rotating structure includes: a support frame, an advertising machine body, a rotating shaft, and a first magnet. The first magnet rotates around the rotating shaft. Multiple second magnets are arranged in a ring at equal intervals on one side of the rotating shaft. The first magnet magnetically attracts the multiple second magnets to limit the position of the advertising machine body. When the user rotates the advertising machine, the first magnet and different second magnets generate magnetic attraction, forming positioning points distributed at equal angles. The magnetic attraction structure achieves stepless adjustment through the magnetic damping effect of the first and second magnets. The user can switch between horizontal and vertical screen modes simply by gently pushing the advertising machine. The magnetic attraction automatically corrects offset, avoiding the wear problems of traditional mechanical buckles. It can flexibly adapt to different usage environments, balancing smooth rotation and reliable positioning, significantly improving the advertising display effect.

A pneumatic tooling auxiliary device for assembling a rigid pipe-rubber hose clamp for a pressurizing pipe is provided. A first tooling fixture (3) is installed on the left side of the workbench (2), and a second tooling fixture (4) is installed on the right side of the workbench (2). A clamping fixture (6) is installed between the first tooling fixture (3) and the second tooling fixture (4). The lower mold of the first tooling fixture (3) is fixedly installed on the workbench (2), and the top of the upper mold of the first tooling fixture (3) is connected upward to the first cylinder (10). The top of the upper mold of the second tooling fixture (4) is connected upward to the second cylinder (11). The bottom of the lower mold of the second tooling fixture (4) is slidably installed on the slide rail (7) through the slide block (17). The slide rail (7) extends in the left and right directions and is fixedly installed on the right side of the top surface of the workbench (2). A clamping fixture (6) is installed on the outer wall of the left side of the lower mold of the second tooling fixture (4). The working coordination between rigid pipes / rubber hoses and clamping fixtures integrates pneumatic components, simplifies layout, facilitates manual operation, and ensures precise clamp assembly. This prevents loosening and detachment, improves assembly quality, and optimizes and saves rework costs.

This invention relates to the field of centrifugal molding technology, and more particularly to an energy-saving, high-efficiency centrifugal molding device for cement poles. The device includes a base, on which an annular steel mold is mounted. The annular steel mold comprises an upper steel mold and a lower steel mold, on which multiple first arc-shaped strips and multiple second arc-shaped strips are respectively installed; a first cover plate and a second cover plate, respectively disposed on both sides of the annular steel mold; a central sleeve fixedly connected to the first cover plate; and a rotating assembly disposed on the first cover plate. The central sleeve of this invention incorporates an air-bag compression vibration mechanism. Through a rotating shaft, the compression ball periodically compresses the air bag, generating high-frequency micro-vibrations that allow the concrete slurry to flow fully, effectively expelling internal air bubbles and pores. This significantly improves the density, impermeability, and frost resistance of the pole, extending its service life and benefiting the production of cement poles.

The utility model discloses a kind of suction mould machine limiting continuous feeding devices, including frame and second pivot, the top of the left and right sides of frame is equipped with guide block, the top of guide block is respectively provided with first positioning slot and limiting protrusion, the left and right sides of frame are equipped with two symmetrical stand columns, first pivot is rotatably installed between two stand columns, two symmetrical reels are installed on first pivot, steel wire rope is wound on reel, one end of steel wire rope is fixed on reel, other end is connected with cylinder;The both ends of second pivot are provided with limiting slot and round through hole.The utility model is connected with the both ends of second pivot by setting steel wire rope, and can be drawn to frame with reel together by reducing motor drive reel rotation and winding steel wire rope, manual handling is not needed, and the working intensity of worker is reduced;By setting guide block and the limiting slot cooperation on second pivot, axial deviation of second pivot on frame can be avoided.
