Service HotlineIn order to solve the problem of nut loosening, various self-locking nuts have appeared, which have complex structure, high production cost, inconvenient installation and unsatisfactory anti-loosening effect. At present, the never-loosening nuts produced in Japan are mostly used, mainly in the form of double nuts. Each nut is provided with an eccentric cam protrusion, and each nut is provided with a groove and an inclined plane to squeeze the cam protrusion of each nut. When pressing, the cam protrusion of the nut will move to a small radius along the slope of the nut, so that the nut will not loosen, but whether it is a nut or a nut, it is always under the action of eccentric force. In addition, various non-loose nuts designed by many manufacturers are to increase the friction between the nut and the fastening workpiece or increase the barb to achieve the purpose of never loosening, but the effect is not ideal.
Sprinkle the excess flat washer 6 on the positioning plate II3-1 on the flat washer positioning plate 3, and shake the flat washer positioning plate 3 by hand. After a short time, the flat washer 6 will be positioned and arranged on the upper positioning plate II3-1. In the flat washer hole 3-7, since the width of the opening groove 113-32 of the baffle plate II3-3 is smaller than the diameter of the flat washer hole 3-7, and the thickness of the upper positioning plate II3-1 is designed according to the thickness of the flat washer 6, each Only one flat washer 6 can be accommodated in the flat washer holes 3-7 of each upper positioning plate II3-1, and then use a brush to remove the excess flat washer

The side surface 5 forms an inner hexagonal prism hole, and the bottom of the inner hexagonal prism hole is processed with a cross groove 10 .
As we all know, screws and nuts are widely used in various mechanical equipment as connectors, so that the mechanical equipment can be easily disassembled, but for equipment whose internal structure needs to be kept secret, it generally does not need to be disassembled after assembly. The nut can be easily dismantled, leaving equipment that needs to be kept secret of the internal structure from being kept secret.
