This utility model relates to the field of road and bridge construction technology, and in particular to a fixing structure for repairing road and bridge cracks. It includes a cylinder and a road surface. A crack groove is provided at the crack in the road surface for placing the cylinder. A top groove is formed above the crack groove. A vertically placed support is slidably installed inside the cylinder. A waterproof plate is fixedly connected to the top of the support after it slides through the cylinder. An inner cavity is formed at the top of the cylinder. Connecting rods are rotatably connected to both sides of a section of the support located in the inner cavity. A pull rod is rotatably connected to the end of the connecting rod away from the support. A fixing rod is provided at the end of the pull rod away from the connecting rod. This application improves construction efficiency and reduces difficulty through convenient adjustment of the fixing structure. Furthermore, the design of barbs and waterproof grooves enhances structural stability and waterproof performance. The mechanical structure under stress also prevents further cracking, ensuring the quality of the repair work in terms of construction efficiency and long-term stability of the repair effect.

The utility model relates to an oil filter technical field, a kind of oil filter connecting structure, including filter cartridge, the connector for oil inlet is installed in filter cartridge upper portion, oil inlet annular groove is established between filter cartridge and connector, the thread groove is established in the upper end in the inside of filter cartridge, filter cartridge is installed in the inside by thread groove, the rotation groove is established in the upper end in the inside of filter cartridge below thread groove, the rotatable ring is rotatably installed in the inside of rotation groove, the rotatable ring surface is established with several oblique through slot, rotatable ring is provided with the cleaning assembly for cleaning the dirt on the surface of filter core. The utility model is driven by the flow force of oil inlet to make the dirt on the surface of filter core be effectively cleaned, further guarantee the filtering effect of oil filter, without setting other driving assembly in the inside, without frequently taking out filter core to clean, ensure the long-time use of filter core, prevent frequent replacement, thereby influence work efficiency.
