The thread section of the bolt is arranged in a deep hole on the engine, an operator uses a wrench to lock the bolt through the installation section during installation, and the operator uses the wrench to loosen the bolt through the disassembly section during disassembly; the ball head of the bolt is connected with the plastic cover hole of the engine cover, the diameter size of the ball head is 0.5mm larger than that of the plastic cover hole, the installation is simple, and the plastic cover cannot be loosened after the installation. Compare with original screw bolt, the bolt carries out screw thread section car processing after through the cold forging shaping, has not only solved the problem of the processing cost height processing difficulty that original direct car processing leads to, and through reducing the diameter of first linkage segment, second linkage segment moreover to and set up the arc arch at first linkage segment, second linkage segment lateral wall, when reducing the quality of whole bolt and having reduced the consume, effectively guaranteed the intensity of whole bolt. In addition, the bolt is made of SCM435 alloy steel, and subjected to quenching and tempering heat treatment, so that the hardness of the quenched and tempered bolt reaches HRC33-38, and the strength of the bolt reaches 10.9 grade; the surface of the bolt is subjected to Maxwell coating, and two coating and two baking are adopted, so that the corrosion resistance requirement of the coating reaches 1000H neutral salt spray test, and the corrosion of the base material does not occur, thereby greatly improving the strength and the corrosion resistance of the bolt.
Further, the disassembling section is arranged in a regular hexagonal prism. When the bolt is convenient to disassemble, the wrench is fixed.
Furthermore, the installation section comprises a regular hexagonal prism section and a limiting flange section, and the regular hexagonal prism section and the limiting flange section are connected in sequence. When the bolt is installed, the wrench is fixed through the regular hexagonal prism section on the installation section; the limiting flange section limits the locking distance of the bolt.
Furthermore, one end of the guide section, which is far away from the thread section, is provided with a conical table. The lock is convenient to be installed in the deep hole.
Above-mentioned technical scheme can find out, the utility model discloses following beneficial effect has: 1) the bolt raw material is subjected to cold heading forming and then thread processing, so that the processing cost of the bolt is reduced while the strength of the whole bolt is ensured, and the raw material cost is reduced by reducing the diameter of the second connecting section of the first connecting section; 2) the connecting section of the bolt and the automobile engine hood is arranged to be spherical, and the mounting section and the dismounting section are arranged, so that the dismounting work of the bolt in the use process is facilitated, and the operation is simple and convenient; 3) and a limiting section flange section is arranged at the position of the bolt close to the thread section, so that the locking-in distance of the bolt is limited.
