Service Hotlinerivet is a nail-shaped object with a cap on one end: in riveting, the riveted parts are connected by their own deformation or interference. There are many types of rivets, and they are informal. Commonly used are semi-circular head, flat head, semi-hollow rivet, solid rivet, countersunk head rivet, Wellingtonblind rivet, hollow rivet, which usually use their own deformation to connect the riveted parts. Generally, cold riveting is used for those smaller than 8 mm, and hot riveting is used for larger ones. But there are exceptions, such as the nameplate on the three-ring lock, which is riveted by the interference between the rivet and the lock body hole. In addition, there are paired rivets, which are special. Divided into two parts, the thicker section of the rod with a cap has a hole in the center, and the other section of the rod with a cap is an interference fit. When riveting, drive the thin rod into the thick rod. Most of the existing rivets are connected by overall deformation to achieve mutual cooperation. In the ultra-fine-pitch display screen, the rivets used to fix the ultra-fine-pitch display screen have a slender diameter. If they are fixed by overall deformation, they are prone to bending and breaking. and other phenomena, the tightening effect is not good or there is no tightening effect, which damages the components, increases the cost, and wastes time and resources.
Generally speaking, WellingtonWellingtonWellingtoncombination screws are widely used in electrical, electric, mechanical, electronic, household appliances, furniture, ships and so on. But the above said that different WellingtonWellingtonWellingtoncombination screws have different functions. For example, Phillips pan head WellingtonWellingtonWellingtoncombination screws are generally used in small electronic products. Larger cross hexagon WellingtonWellingtonWellingtoncombination screws are used in larger electrical products, such as frequency converters, and some larger frequency converters use many cross hexagon WellingtonWellingtonWellingtoncombination screws. Hit the inverter case. To loosen the tightening effect. For example, two WellingtonWellingtonWellingtoncombination screws with flower teeth, which are used on the inverter, are used to break the paint, so that all the two WellingtonWellingtonWellingtoncombination screws on the surface of the casing are powered on. There is also a two-WellingtonWellingtonWellingtoncombination screw with a square pressure line, which itself is a two-WellingtonWellingtonWellingtoncombination screw with a pan head screw and a square pad. It is generally used on the surface of the terminal block. The function is for wiring and for crimping.
In order to achieve the above purpose, Guangdong Yueluo Hardware Industry Co., Ltd. provides the following technical solutions: self-expanding semi-solid installation rivets, used for connecting and perforating two or more units of parts, including top core and rivet body, characterized in that : The top core lock slot opened on the concentric sheath along the longitudinal direction is snapped into and screwed and fixed in the concentric sheath, the top core extends downward into the top core rotary sleeve, the concentric sheath The sleeve is connected with the upper sealing sleeve of the lower body and is connected with the longitudinal axis, a hollow body is arranged below the rivet body, a joint is installed under the hollow body, and a supporting foot is connected to the joint, and the supporting foot and the turning The folding clips are staggered and distributed, the folding clips are concave-convex inclined surfaces, and the supporting feet are slidably connected with the folding clips.
At present, the electrical control boxes of the market regulators all include a box body with built-in circuit board components and a box cover that is fastened together with it. The box cover is mostly fastened on the box body by self-supplied screws. The following problems are: First, there are many electric control lines on the circuit board in the box. When installing the self-supplied screws, the electric control lines may be damaged, which may easily cause a short circuit of the electric control, which is a potential safety hazard; Electric batch and other tools are inconvenient to install and disassemble, and the production cost is high.
