Problems solved by technology
[0002] The existing nut is an important fastener accessory, its main function is to fasten, but after a long time of use, the existing nut is in a state of vibration for a long time on the moving object, and it tends to loosen, so it is easy to wear , fall off, often lead to major accidents, causing unnecessary losses, especially some traditional connecting devices, which have high requirements for fastening and tight pressure. Fastened by bolts, also easy to loosen
Nuts are mainly used for the connection of parts. The bolts are inserted into the screw holes, and then the nuts are tightened with tools to realize the connection of two parts. However, when used in C-shaped steel connection devices, the installation process of bolt connection is complicated, and the bearing capacity of nuts is relatively high. Small, especially when the connection position of C-shaped steel needs to be changed, it is necessary to recalculate the bearing capacity of C-shaped steel, etc., so the installation position cannot be changed at will. If the installation position of C-shaped steel can be changed after calculation, the material and labor costs will increase a lot accordingly
