Description

Technical Field

[0001] The utility model belongs to the field of nuts, and in particular relates to a nut assembly and a nut connecting mechanism. Background Art

[0002] Nuts are connecting structures used to mate with externally threaded components such as screws and rods. They are widely used in the connection between components and products. In some existing products, in order to more stably fix the nut in the housing, the nut is usually placed in a mold and fixedly embedded in the housing through injection molding. However, this method has the following disadvantages:

[0003] 1. When the nut is placed in the mold, the nut needs to be embedded in the shell, which results in the position for placing the nut in the mold being relatively deep, and the position for placing the nut is not in a horizontal state. This makes it inconvenient for the operator to place the nut in the mold, and there is a certain risk; it also makes the efficiency of the injection molding process lower.

[0004] 2. The nut cannot be disassembled after being embedded in the shell. It cannot be replaced when the nut is damaged, and it cannot be replaced with nuts of different inner diameters to meet the connection requirements of external threaded parts of different sizes. Utility Model Content
