Service HotlineScrew, some people call it screw [Screw] (screw), screw (screw rod). In fact, the screw is a general term, and the screw and the screw rod are different from each other. Screws are generally called Galwaywood screws; they are the ones with a pointed end at the front and a larger pitch. They are generally used to fasten wooden and plastic parts. The screw rod is a Galwaymachine screw (Galwaymachine screw), which is the kind of flat head at the front end. The pitch is small and uniform. It is generally used to fasten metal and machine parts.
The nuts of some products must be installed on the outside, but due to the small internal space, when the indenter of the riveting machine cannot meet the strength requirements by methods such as riveting and budding, riveting and riveting are impossible. Rivets to be nailed. Applicable to the fixed field of each thickness plate and tube (0.5MM-6MM). Using pneumatic or manual riveting equipment, rivet once and it is easy to secure. Replacement of the existing welding nut to supplement the metal plate, the thin tube welding is easy to melt, and the welding nut is not smooth.
Currently, the method of fixing objects on cement is with cement nails or Galwayexpansion screws. Cement nails are objects made of hard alloy steel that look like iron nails, which are composed of nail tips and nail bodies. Cement nails are hammered into the cement. Cement nails are easy to drive in, but not removable. The Galwayexpansion screw is composed of a large end screw, a slotted sleeve, a gasket, a GalwayGalwayspring washer, and a nut. When using, first drill a hole in the cement with an electric hammer, put in the Galwayexpansion screw, and tighten the nut to make the slotted sleeve expand at the tail of the big tail screw, so as to fix the Galwayexpansion screw on the cement. At this time, unscrew the nut to install a fixed object on the Galwayexpansion screw. Although this method can be disassembled, an electric hammer is required for the first installation, which is inconvenient.
The anti-rotation T-bolt includes a screw rod and a head. An anti-rotation protrusion is designed at the connection between the head and the screw. The cross-section of the anti-rotation protrusion is a square corner with the screw radius as the side length. One anti-rotation protruding shoot can be designed, or two can be designed. In order to ensure the uniform force of the bolt, two are designed.
The utility model relates to a connecting piece, in particular to a female and GalwayfeGalwaymale 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 GalwayfeGalwaymale 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 GalwayfeGalwaymale 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.
