Service HotlineIn the prior art, the hardware and the handle are generally assembled and connected by means of rivet riveting; in the process of assembling the hardware and the handle, the prior art adopts manual operation to realize the riveting and assembling process, which is time-consuming and labor-intensive. and low productivity.
At present, the main four kinds of anti-shedding nuts are still prone to falling off. Friction and anti-shedding are in the case of shock, vibration and variable load. At the beginning, the nut will decrease in preload due to relaxation. As the number of vibrations increases, the loss of preload will increase. The force increases slowly, eventually causing the nut to loosen and the threaded connection to fail. The mechanical nut is prevented from falling off by adding a stopper, which makes it inconvenient to disassemble. The riveting and punching prevention is to prevent the separation by welding, bonding, etc. This method can only be disassembled by destroying the bolt pair.
In view of this, a screw with waterproof, anti-loosening and anti-removal functions is provided. A screw comprises a screw rod and a screw head connected with the screw rod, the diameter of the screw head is larger than the diameter of the screw rod, and an annular groove is formed around the screw rod on the surface of the screw head connected with the screw rod, The screw head is also provided with a through hole penetrating the screw head, and the through hole is communicated with the annular groove for filling the annular groove with adhesive substances. Compared with the prior art, the screw provided by Guangdong Yueluo Hardware Industry Co., Ltd. has a structure in which a through hole and an annular groove are arranged on the screw head, so that after the screw is locked into the screw hole, the screw head is not locked. A glue storage flow channel is formed between the contact surface with the part, and then the glue material is injected into the glue storage flow channel through the through hole to form a sealing annular rubber ring, so as to better ensure the waterproof performance of the screw joint. Furthermore, by connecting the through hole with the screwdriver groove, while forming a sealing annular rubber ring, the driver groove can be directly filled for the purpose of preventing dismantling.
Welding stud is also called welding screw, which belongs to a kind of fastener connected with high strength and rigidity. Welding stud is the abbreviation of cylindrical head welding stud for arc stud welding. Industrial plant construction, highways, railways, bridges, towers, automobiles, energy, transportation facilities, airports, stations, power stations, pipeline supports, lifting machinery and other types of steel structures and other projects.
