Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a high-strength double-tensile spring nut. Background Art

[0002] A spring nut is a common fastener, usually used to connect threaded parts with unconventional shapes. It consists of a group of bent and elastic thin sheets, which can be bent to form a shape similar to locking, so as to provide stronger fastening force and anti-loosening effect. The structure of the spring nut is relatively simple, usually composed of two parts, an inner and an outer part. The inner part is the basic form of the nut, and the outer part is the elastic spring sheet wrapped around the nut. Spring nuts are usually applied in various industries, especially in the mechanical and construction industries. They are usually used to connect pipes, parts of complex structures, such as capping, wheels, etc. The advantages of spring nuts are easy installation and disassembly, maintenance, prevention of loosening and detachment of connecting parts. At the same time, due to their relatively low material cost, they have good reliability and economy. There are already various standards, such as American standards, British standards, and international standards, etc. For general applications, such as general machinery, automobiles, and other industrial applications, ISO standard nuts are a more widely used standard. The selection of spring nuts should also consider factors such as the required working load, the number of thin sheets, materials, and operating environment, etc.

[0003] The application number is CN202123371337.8, which discloses a high-strength and convenient double-tensile spring nut, including a first clamping piece, a second clamping piece, a connecting piece, an elastic piece, a first fixing cylinder, and a second fixing cylinder. The first clamping piece and the second clamping piece are connected by the connecting piece. The middle area of the first clamping piece is empty. The elastic piece extends from the first clamping piece. The first fixing cylinder is connected to the elastic piece, and the second fixing cylinder is connected to the second clamping piece. The elastic piece and the second clamping piece are used to clamp the first fixing plate. The second fixing cylinder is used to be inserted into the hole of the first fixing plate to limit the movement or detachment of the first fixing plate. The lower part of the second clamping piece is used to place the second fixing plate. The first fixing cylinder is used to lock the bolt passing through the second fixing plate, the second clamping piece, the first fixing plate, and the elastic piece to realize the fixed connection between the first fixing plate and the second fixing plate. The utility model has a simple structure, is easy to use, and has a high connection strength.

[0004] Although the above utility model is connected by a connecting piece between the first clamping piece and the second clamping piece, the middle area of the first clamping piece is empty, the elastic piece is led out from the first clamping piece, the first fixed cylinder is connected to the elastic piece, the second fixed cylinder is connected to the second clamping piece, the elastic piece and the second clamping piece are used to clamp the first fixing plate, and the second fixed cylinder is used to be inserted into the hole of the first fixing plate to limit the movement or detachment of the first fixing plate; the second fixing plate is placed below the second clamping piece, and the first fixed cylinder is used to lock the bolt passing through the second fixing plate, the second clamping piece, the first fixing plate and the elastic piece to realize the fixed connection between the first fixing plate and the second fixing plate. The utility model has a simple structure, is convenient to use and has high connection strength, but the disadvantage is that when the device is used, and the corresponding tightening of the nut is relatively unified, it is necessary to fix the fixing bolt with a unified thread, because it does not have a wider application scenario.

[0005] Therefore, it is necessary to replace the originally fixed threaded component on the device with a replaceable nut component, so that when the device is used, the corresponding threaded nut can be replaced for threaded rods with different threads, so that a spring nut can have a more comprehensive, flexible and wider application.
