Production of 304 stainless steel hexagonal flange with gasket oil plug, flange face plug, oil plug, plug, and blind end stop payment

After threading the threaded cap, connecting rod, and screw, the washer with the installation through hole is threaded through the connecting rod through the installation through hole, causing the screw to press and deform relative to one end of the connecting rod to form a convex tooth structure. The outer diameter of the convex tooth is larger than the inner diameter of the installation through hole to form a washer, aiming to reduce the process of manual penetration of the washer. The threaded flange with a washer increases the contact area between the nut and the washer, Enhanced friction between nuts and washers, avoiding easy loosening after screw tightening and installation, improving the stability of screw tightening. When installing screws, the fixing part can be hung on the fixing groove of the installation plane, preventing the washer from rotating with the rotation of the screw, making it easier to tighten the screw. Most of the existing belts use fasteners to fix the other end of the belt to control the belt length. If the fasteners are often used for a long time, they need to be deformed and damaged. The user stands up and sits down to change the position. After dinner, the belt circumference needs to be adjusted. In order to solve this problem, it is necessary to design a belt suitable for people's waist, and connect both ends of the belt with buckles, Adjust the tension of the belt as needed.

Nowadays, when installing outdoor air conditioning units, most of them need to be hung on the outer wall. Therefore, when tightening the foot screws, everyone outside the window needs to crawl and use a wrench to tighten them. Therefore, the handling of installers becomes difficult, as installation materials such as screws and nuts are prone to falling off, leading to significant safety accidents such as material waste and hand pulling, resulting in unnecessary losses. The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to solve the above problems by providing a safe and labor-saving foot screw installer for outdoor air conditioning units, which is not easy to drop even if the installer does not squat outside the window or walk out of the room.

In the prior art, the early rivet is a small wooden or bone stud, and the early metal Amoeba may be the ancestor of the rivet we know today. Undoubtedly, they are ancient methods of metal connection known to humans, dating back to the early use of malleable metal. For example, during the Bronze Age, the Egyptians used rivets to fasten the six wooden fan shapes on the outer lines of slotted wheels together. After the Greeks successfully cast large statues in bronze, they used rivets to rivet the various components together. With the progress of the times, the types of rivets also increased, However, traditional rivets have the problem of insufficient connection strength, so a new type of rivet is needed to solve the above problem.

When used for the connection and fixation of doors, windows, cabinets, and other hinges, traditional screw fastening methods are usually used. The screws are directly inserted into the screw holes of the connected parts, where the screw end caps are directly exposed. This not only affects the aesthetics of the connected parts, but also the screw end caps that are exposed for a long time are prone to rust. Additionally, there are burrs in the processing of the screw ends, which can easily scratch personnel when used for fastening connections, It affects both aesthetics and safety.

A rivet is a nail shaped object used to connect two parts or components with through holes and a cap at one end. In riveting, the riveted parts are connected using self deformation or interference. There are many types of rivets, and they are not limited to form. In today's product production, slot holes on the same installation surface often have different installation slot hole depths. If mechanical tools are used for quick screwing installation, it will directly cause destructive effects on brittle products, leading to product cracking and damage. When connecting plastic shells, lightweight boards, insulation materials, circuit boards, or any other lightweight and lightweight materials, the installation process requirements are also relatively high, When people manually operate, the grip and bonding force of the rivets themselves on the installation surface are weaker than those installed by mechanical rotation. The bonding strength of the rivets used for manual operation needs to be enhanced, and the rivet structure needs to be improved and strengthened when installing lightweight materials.
