Service HotlineWith the development of the economy, automobiles have become an indispensable means of transportation in people's lives, and the production, sales and after-sales services of automobiles have also developed rapidly. Automobile wheels and steel rings are an important part of auto parts and are also related to The use of the car is safe. The connection between the car wheel and the steel ring is realized by bolts, so the bolts and nuts need to have good fixation.
In order to overcome the above problems, Guangdong Yueluo Hardware Industry Co., Ltd. provides a screw that can be quickly installed and removed. Using the principle of lever, press the handle downward, and the screw can form a backward force through the connecting piece. Press the screw and nut tightly; lift the handle, the screw forms a forward force, and the screw can be removed. Thus, the time and manpower for screwing during installation and disassembly are reduced. The solution adopted by Guangdong Yueluo Hardware Industry Co., Ltd. to solve its technical problems is that the entire screw includes a screw rod, a nut, a connecting piece, a circlip, a positioning pin, a small shaft, a fixed piece, a base, and a handle; the screw is connected by the small shaft at the upper end. At the upper end of the connecting piece, the handle is connected to the lower end of the connecting piece, and the front end of the handle is connected to the base fixing piece through a positioning pin. There are gaps at both ends of the small shaft, and the small shaft is installed through the circlip. The front end of the handle can only be rotated on the positioning pin. Due to the lever principle, when the handle is pressed down, it will drive the screw at the front end of the connecting piece, so that the screw generates a backward force and tightens the screw and the nut. On the contrary, when the handle is pulled up, the screw generates a forward force, so that the screw can be easily removed. The beneficial effect of Guangdong Yueluo Hardware Industry Co., Ltd. is that the quick-opening screw saves the time and labor of repeatedly twisting the nut during installation and disassembly. The installation and removal process is simple.
Anti-corrosion technology Stainless steel screws are made of metal, and there are four main methods for metal anti-corrosion, namely the properties of the material itself, the environment of use, the interface between materials and the environment, and the improvement of the metal structure design. If a complete anti-corrosion alloy is used to make stainless steel Screws, unless there is a special need, are not cost-effective in terms of economics, and it is also impractical to completely isolate the appearance of the screw from environmental elements that can cause corrosion. Improving the metal structure design can improve the influence of special circumstances under certain conditions, but the design of most stainless steel screws cannot be fully corrected, and its maintenance effect is not permanent, so this method cannot basically solve the problem, as long as it is on the surface. Top anti-corrosion, that is, surface anti-corrosion treatment is the most widely used method. The anti-corrosion treatment on the surface of stainless steel screws refers to the use of various methods to apply a protective layer on the metal surface. The purpose of avoiding or mitigating corrosion. The protection layer should be able to meet the following requirements: 1. Corrosion resistance, wear resistance, high hardness, 2. The structure is tight, intact, and the pores are small. 3. It has strong separation and good adhesion with the base metal. 4. It is evenly distributed and has a certain thickness. The maintenance layer is usually divided into two types: metal coating and non-metallic coating. Metal coating refers to the use of metal or alloy with strong corrosion resistance to form a maintenance layer on the surface of metal that is easy to corrode. This coating is also called plating. There are quite a few methods and varieties to produce metal coatings, the most common of which is electroplating, followed by molten metal immersion plating (hot dipping) and chemical surface treatment. Non-metallic coating refers to the use of organic polymer materials such as paint and inorganic materials such as ceramics to form a protective layer on the surface of metal equipment or parts. The protective layer can completely isolate the base metal from the environmental medium and prevent the base metal from corrosion due to contact. Corrosion is formed in the medium of stainless steel standard parts.
In another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the discharge port of the vibrating plate 2 is matched with the screw receiving hole 35, and the screws can enter the screw receiving hole 35 through the discharge port after sorting and sorting in the vibrating plate 2. . Preferably, a guide rail 6 is provided between the discharge port of the vibrating plate 2 and the screw accommodating hole 35, and the screws enter the screw accommodating hole 46 from the discharge port through the guide rail 6. The slotting is carried out, which improves the efficiency and saves the labor cost.
Most of the blind hole installation rivets have the characteristics of light weight, reliable connection, high strength, and convenient and quick installation. For example, blind rivets have been widely used in various aerospace vehicles.
