Embodiment 1

[0029] Example 1, such as figure 1 The knock nut assembly of the present invention shown includes: an upper nut 1, a middle knock washer 2 and a lower bevel washer 3, and the upper nut 1 can be rotated and tightened or loosened on a bolt; the middle knock washer 2 The surface in contact with the lower bevel gasket 3 is a bevel, that is, wedge-shaped, with a strip-shaped hole on it, and the two ends of the hole are semicircular; the contact surface of the lower bevel gasket 3 and the middle tightening gasket 2 is a bevel, The inclination of the bevel is the same as that of the bevel of the middle knocking washer 2; the knocking nut assembly can be tightened or loosened by knocking the middle knocking washer 2. When the nut is tightened, the upper nut 1 is first rotated and tightened slightly, and then the middle tightening washer 2 is struck to tighten the tightening nut assembly; After loosening, the tightening nut assembly can be directly removed or the upper nut 1 can be ro...

Embodiment 2

[0030] Example 2, such as figure 2 and 3 As shown in the tightening nut assembly of the present invention, there are concave and convex grooves on the inclined surface of the middle tightening gasket 2 and the inclined surface of the lower inclined gasket 3, which are used to prevent the tightening nut assembly from loosening.

Embodiment 3

[0031] Example 3, such as Figure 4 As shown in the tightening nut assembly of the present invention, after the middle tightening washer 2 is tightened, the end of the middle knocking washer 2 is knocked, so that the end of the middle tightening washer 2 is bent, which can prevent the tightening nut assembly from loosening.

Abstract

The invention relates to a staked nut assembly. The staked nut assembly consists of an upper nut, a middle staked spacer and a lower bevel spacer. A knocking manner is adopted for fastening a contact,high fastening pressure is easy to obtain, the condition that the nut is released due to vibration influence, and the rusty nut is still easy to release, can be avoided, and the construction efficiency is greatly improved.

Description

technical field [0001] The present invention relates to the field of nuts, and more particularly, to a driving nut assembly. Background technique [0002] At present, the nuts usually need to be rotated to tighten or loosen. When the nuts pressurize or loosen the joints, a large torque is required. The construction is time-consuming and laborious, and it is easy to be affected by vibrations and loosen by itself. When the nut is rusted, it is difficult to turn it loose again, and it is usually necessary to break the nut. The nut tightening assembly of the present invention tightens the joint by knocking, which is easy to obtain greater tightening pressure, prevents the nut from loosening due to vibration, rusty nuts are still easy to loosen, and the construction efficiency is greatly improved. Contents of the invention [0003] In order to overcome the shortcomings of the background technology, the tightening nut assembly of the present invention has the following advantag...
