An adjustable and non loosening screw installation structure and a method for making installation nuts
This utility model belongs to the field of screw structure technology and relates to an adjustable and non loosening screw installation structure and installation nut.
1. Background technology:
With the development of the power electronics industry, the degree of product modularization is increasing. In existing technology, the installation and fixation of modules are generally connected to the cabinet through mounting plates using screws; In order to prevent the screws from falling off during module disassembly and assembly, loose
Why are waterproof nut columns used in steel structures?
The main reason for using waterproof nut columns in steel structure buildings is to prevent moisture from entering the interior of the structure, which can lead to corrosion and damage. Due to the fact that steel structure buildings are commonly used in outdoor environments and are susceptible to the influence of natural environments such as rainwater and snow, measures need to be taken to protect the safety and stability of the structure.
Waterproof nut columns are usually made of stainless steel material, which has good corrosion resistance and waterproof pe
The difference and characteristics between non loosening nuts, waterproof nut columns, and rivet nuts
Loose nuts, waterproof nut columns, and rivet nuts are three different types of nut connection methods, each with its own characteristics and applicable scenarios:
1. Non loosening nut: Non loosening nut is a special type of nut with a special structure usually machined inside the thread, so that the nut can still remain on the bolt after loosening and will not completely fall off. This type of nut is suitable for situations that require frequent disassembly and installation, which can reduce the loss and damage of the nut.
The rapid development of domestic high-end fasteners, high-strength rivets and bolts, etc
Since entering the new century, in the face of the rapid rise of China's emerging industries, high-end equipment manufacturing industry for core pulling rivets, and the rapid development of urban transportation facilities, high-rise buildings, and national defense construction, the High Strength Fasteners and High Strength Bolt Research Institute has formed a strategic alliance, constantly striving for self-improvement and independently developing domestically produced high-strength rivets with completely independent intellect
What is the difference between rivet nuts and pull rivet nuts?
Although there is only a one word difference between rivet nuts and pull rivet nuts, there is a clear difference in their use.
1. Rivet nut (pressed in nut): A rivet nut is a type of nut that is fixed to a workpiece by pressing or fitting. It is usually made of metal materials and has one or more threaded holes for threaded connections. Rivet nuts are suita
The difference between sheet metal rivet nuts, expansion rivet nuts, and pull rivet nuts
Sheet metal rivet nuts, expansion rivet nuts, and pull rivet nuts are three different ways of fixing nuts, and their differences are as follows:
1. Riveting nut: Riveting nut is a method of fixing the nut onto the sheet metal by riveting. Riveting nuts usually require drilling a hole in the sheet metal, and then pressing the nut into the hole through the ri
Three major heat treatment methods for stainless steel screws
In general, in stainless steel standard parts, the heat treatment of stainless steel screws is determined based on the hardness of the screws themselves. Common heat treatments include tempering heat treatment, chemical heat treatment, and localized heat treatment. The first two types of heat treatment are designed for the whole, and that type of heat treatment is for local treatment. Regardless of which heat treatment method is used, it is very important for the screw itself. Different hardness uses different heat treatment m
How to prevent the malfunction of stainless steel screws being locked
Locking or biting often occurs on screws made of stainless steel, aluminum alloy, and titanium alloy materials. These metal alloys themselves have anti-corrosion properties, and when the surface is damaged, a thin oxide layer is formed on the metal surface to prevent further corrosion. When the screws of stainless steel are locked, the pressure and heat generated between the grooves will damage this oxide layer, causing blockage or shear between the metal threads, leading to adhesion. When this phenomenon continues to occur, i
Commonly used stainless steel fasteners, austenitic stainless steel
Austenitic stainless steel
The commonly used grades are 302, 303, 304, and 305, which are the so-called "18-8" austenitic stainless steel grades. Both corrosion resistance and mechanical properties are similar. The starting point for selection is the production process method of fasteners, which depends on the size and shape of the fasteners, as well as the quantity of production.
