6results about How to "High shielding" patented technology

This application relates to the field of optical thin film technology, and more particularly to a diffusion film, its preparation method, and its application. A diffusion film is provided, comprising a substrate and a diffusion film disposed on any surface of the substrate. The diffusion film is prepared from components with the following mass percentages: 0.5%–10% diffusion particles and 90–99.5% solvent. The resulting diffusion film exhibits high haze, high clarity, and high light transmittance. The provided formula is simple, reduces the use of other components, is low in cost, facilitates the dispersion of diffusion particles, achieves ideal light diffusion effects, and is suitable for widespread use.

This invention proposes a masking fixture for spraying paint on a battery pack frame. The battery pack frame includes a base plate, with a frame on each side of the back of the base plate and a connecting bracket on the outer side of the frame. The masking fixture includes a masking frame, which is fitted onto the outside of the base plate, with only the front of the masking frame exposed. The masking frame and the battery pack frame are detachably connected. This invention, by designing a masking frame that matches the base plate of the battery pack frame, masks the non-painted areas of the battery pack frame, ensuring that only the front of the masking frame exposes the front of the base plate to be painted. This facilitates operation, eliminates the need for using high-temperature resistant tape to partially mask non-painted areas, and greatly improves work efficiency.

The utility model discloses a plasma spraying adhesive tape which comprises a winding disc, an adhesive tape body is wound on the winding disc, two grooves are formed in the side wall of the winding disc, fixing blocks are arranged in the two grooves, the adjacent sides of the two fixing blocks are jointly and fixedly connected with a cross rod, the cross rod is fixedly connected with a winding roller, and the winding roller is fixedly connected with a motor. The front sides of the two fixing blocks are jointly and fixedly connected with a rectangular plate. The adhesive tape is not easily influenced by high temperature, the plasma spraying quality is ensured, meanwhile, the protective layer is used for protecting the base layer, the base layer is prevented from being damaged or corroded in the transportation or storage process, the service life of the adhesive tape body is prolonged, meanwhile, the end of the adhesive tape body is convenient to find, and bubbles in the adhesion layer are reduced during adhesion.

The invention discloses an artificial turf weather resistance detection device, and relates to the technical field of weather resistance detection devices.The artificial turf weather resistance detection device comprises a detection cabinet, a cabinet door, a placement table, a sliding frame and an ultraviolet lamp, the cabinet door is rotationally installed on the inner wall of the detection cabinet, the placement table is slidably installed at the bottom of the inner wall of the detection cabinet, and the sliding frame is slidably installed on the inner wall of the detection cabinet; the weather resistance detection device comprises a movable device which is used for enabling the lawn to be conveniently taken out and put in, the movable device is arranged on the inner wall of the detection cabinet, the edge of the lawn is pressed through automatic rotation of a pressing block, meanwhile, a movable plate sinks, and the surface of the lawn is lowered to the position flush with or slightly lower than the edge of the placement table; the sample is prevented from warping and shifting due to thermal expansion, airflow or vibration in a test, the device moves reversely when the device is opened, the movable plate can stably support the sample, and the lawn can be conveniently taken out.

The utility model discloses a roof rack type folding shed, relates to the technical field of automobile accessories, and aims to provide a solution for conveniently converting the roof rack type folding shed into an independent shed structure. The roof rack comprises a roof rack body and a fixed connecting piece thereof, and is characterized in that the roof rack body is provided with a cross beam and a vertical beam which are symmetrical front and back, and pull rods capable of moving left and right are arranged on the two sides of the cross beam and connected with the cross beam through telescopic sliding rails; the two ends of the pull rod are provided with a rotating limiting assembly and a telescopic stand column assembly, and it is ensured that the device can be folded into a roof rack shape when not used and converted into a stable independent shed structure when needed. In addition, all-directional shielding is achieved by arranging a tie bar, a front blocking face, a rear blocking face, a left blocking face, a right blocking face and other components. The design particularly pays attention to space management in the process of converting from the roof rack to the shed structure, so that collision or friction with other parts of the vehicle is avoided; all the components can be folded and fixed on the roof rack, so that the occupied space is small.
