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 application provides a luggage rack and a vehicle, and aims at at least solving the problem of difficult assembly of the luggage rack. The luggage rack is installed on a roof of the vehicle. The luggage rack comprises a main body, a decoration and a light-emitting part. The main body is buckled with the decoration to form an installation cavity with a ring-shaped peripheral wall. The light-emitting part is arranged in the installation cavity. During installation, the light-emitting part is arranged in the installation cavity, and then the decoration is buckled with the main body, so that the installation is completed. The installation difficulty is reduced, the assembly speed is improved, and the production efficiency is improved.
