The utility model relates to a connecting piece, in particular to a female and female screw used for shaping products in interior decoration. In the current decoration project, when fixing the decoration stereotyped product, the process is complicated, so labor-intensive and time-consuming, the construction cost is high, and the construction degree is low. For example, the decorative board for fixing the wall, the main process step used in its operation is the leveling of the nail strip. That is to say, saw the wood to the required specifications, then draw horizontal and vertical lines on the wall, and then nail the wooden strips to the wall according to the horizontal and vertical lines, and then glue and glue the board. The first step is to install the lines, color and paint. It can be seen that it is quite troublesome to use the above method to construct. The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a female screw, which can skillfully connect decorative products to the wall. As conceived above, the technical solution of Guangdong Yueluo Hardware Industry Co., Ltd. is a female screw, which is characterized in that both ends of the screw are threaded, the screw-in end is screwed into the plastic expansion tube inserted into the wall, and the other end of the screw is threaded with the same A female piece is mated and connected. The other end of the screw can also be barb-shaped and directly fit with the decorative board. The screw thread of the screw-in end is a wood thread, and the thread of the mating connection end with the female part is a machine thread.

Now the screw itself is made of metal, so it is easy to rust, especially screws in harsh weather environments that are exposed to the air for a long time, such as air conditioners, wires, etc. In the existing technology, the shape of the screw has been fixed, and the structure of the screw itself is composed of a shaft with twill in the middle and a polygonal structure with stripes on the outside. OK, but because of the installation of some equipment, it needs to be exposed to the air for a long time. For example, the outdoor unit of the air conditioner must be installed in the outdoor area, and the outdoor can not be sheltered from wind and rain, so after long-term sun and rain, the screw The surface is easy to rust. If the rust is serious to a certain extent, the nut will be embroidered to death. Once the external machine needs to be disassembled one day, the embroidered screw will lose its use value and give workers to the workers. The disassembly and assembly of the screw has caused a lot of trouble, because the embroidered screw cannot be unscrewed directly. The only method used is to cut off the shaft in the middle of the screw with a hacksaw, or discard the entire screw structure. Since the shaft in the screw has been inserted into the middle of the wall, this waste is not good for both aesthetics and safety. To solve the rust problem of the screw, the existing technology is to improve the material of the screw, or to maintain it regularly, but this method itself is time-consuming and labor-intensive, and it is a waste of resources.
