Abstract

The invention discloses a quick nut assembly, which overcomes the deficiencies of the traditional nut assembly and caters to the habit of using traditional nuts and washers. The technical scheme is as follows: the quick nut assembly includes quick nuts, bolts and nut washers, wherein the quick nut is provided with a protrusion, the nut washer is provided with a step hole, and the quick nut is provided with a protrusion in the assembly of the quick nut, the nut washer and the bolt. into the stepped hole of the nut washer. Such a design only requires a slight modification to the locking parts of the traditional nut and screw, without adding any additional parts, the manufacturing cost in actual use can be greatly reduced, and it has played a positive and practical role in promoting the use.

Description

technical field [0001] The invention relates to a fastener, in particular to a quick nut assembly. Background technique [0002] When the screw (bolt) and the nut are connected and tightened, the two parts that need to be connected due to the design will be exchanged, resulting in a change in thickness. In the case of fastening thin parts, the screw rod (bolt) cannot be replaced due to the large difference in thickness of the parts, and the nut needs to be screwed in for a long distance to reach the locked position, which is time-consuming and laborious. [0003] In addition, for screw rods (bolts) and nut assemblies that require a large distance adjustment in length and can be fine-tuned to adapt to different working conditions, the time to screw in and out is longer. It will also encounter fastening occasions where the thread is located in the middle section of a cylinder of equal diameter (traditional nuts cannot be screwed in). [0004] Traditional bolt and nut fastene...
