Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, an anti-rotation anchor bolt fastening assembly includes a nut 1, a washer 2 is fixedly installed at the bottom of the nut 1, a screw 14 is fixed at the bottom of the washer 2, a nut 13 for fixing a part is installed on the screw 14 in a threaded manner, a plurality of notches 3 are uniformly formed on the outer side of the washer 2, one or more limiting assemblies 4 are clamped at the notches 3, in this embodiment, the limiting assemblies 4 are arranged in three groups, and the three groups of limiting assemblies 4 are arrayed circumferentially with the axis of the nut 1 as the center of a circle.

In the first embodiment of the limiting assembly 4, the limiting assembly 4 comprises a pawl 5, a first spring 7 and a first mounting plate 6, specifically, the pawl 5 is clamped in the notch 3, the first mounting plate 6 is rotatably mounted at the bottom of the pawl 5, one end of the first spring 7 is fixed on the pawl 5, the other end of the first spring 7 is fixed on the first mounting plate 6, meanwhile, the bottom of the first mounting plate 6 is flush with the bottom of the gasket 2, and a mounting hole 12 for fixing the first mounting plate 6 with a part is formed in the first mounting plate 6.

Through the technical scheme, insert screw rod 14 in the through-hole between two parts, the gasket 2 and the first mounting panel 6 of nut 1 bottom all are hugged closely on the surface of part this moment, afterwards accessible mounting hole 12 is fixed first mounting panel 6 one by one with the part, and guarantee pawl 5 is located breach 3 department, when fixed the part, rotatory nut 1, nut 1 is rotatory at the gasket 2 of rotatory in-process synchronous drive bottom, and stir elastic connection's pawl 5, if the condition of screw rod 14 gyration appears, then pawl 5 hugs closely in breach 3 department under the effect of first spring 7, restrict the screw rod 14 that has gyration to drive, thereby can prevent effectively that holistic crab-bolt from appearing gyration the condition, with the fixed effect of improvement to the part, avoid the potential safety hazard that brings because the crab-bolt drops.
