Combined embedded nut for automobile door glass bracket

Abstract

The invention discloses a combined embedded nut for an automobile door glass bracket. The combined embedded nut is characterized in that one end part of a first nut main body of a first nut extends outwards in the radial direction to form a first nut rim, a first connecting through hole is coaxially formed in the first nut main body, a plurality of preset torque pressure points are uniformly distributed on the first nut, the first nut rim is arranged to be of a non-cylindrical structure, one end part of a second nut main body of a second nut extends outwards in the radial direction to form a second nut rim, a second nut internal threaded hole is coaxially formed in the second nut main body, the automobile door glass bracket and automobile glass are locked on a glass lifter assembly throughthe two nut threaded through holes, the outer cylindrical surface of the second nut main body is a non-smooth surface column, the second nut rim is arranged to be of a non-cylindrical structure, andthe first nut and the second nut are integrated with the automobile door glass bracket through injection molding and are in close fit with each other. The nut is simple in forming structure, reliablein performance and low in cost, can be formed at a time, improves the material utilization rate, meets the light weight requirement and has the anti-loosening performance.

Description

technical field [0001] The invention belongs to the technical field of fastener manufacturing, and in particular relates to a combined inlaid nut for an automobile door glass bracket. Background technique [0002] In the automobile industry, the door glass bracket 100 is usually made of plastic (nylon), and the glass is bonded in the groove portion 110 on the door glass bracket 100. An inlaid nut 200 is arranged at the lower end of the door glass bracket 100, and the inlaid In the door glass bracket 100 , it can be seen as a whole with the door glass bracket 100 . [0003] Through the internal thread 210 of the inlay nut 200, the door glass bracket 100 and the glass assembly are locked on the glass regulator assembly, so that the inlay nut 200 can lock the glass bracket assembly to the door glass regulator assembly. At the same time, it is required that the joint between the door glass bracket 100 and the inlaid nut 200 must be able to withstand a certain pull-off force and...

AI Technical Summary

Problems solved by technology

[0006] The inlaid nut 200 of the prior art mentioned above has an integrated structure and complex structure, and usually requires special cold heading forming equipment, or machining the middle groove part after cold heading forming, or adopting a full machining process for production

In addition, the non-circular structure of the overall shape (end) will cause intermittent cutting in the subsequent turning process, which will easily cause tool damage, low processing efficiency and high cost
