Problems solved by technology

Existing screws are all fixed by the cooperation of threads. Due to the large number of threads, it is often necessary to rotate many turns when tightening to tighten, resulting in a waste of time and very inconvenient. The quick lock screws currently on the market The head is flat, and it is difficult to align the nut at once, and the existing screw processing technology is not suitable for the processing of this kind of screw.

Embodiment 1

[0021] A screw, comprising a first rod body 1, one end of the first rod body 1 is connected to a second rod body 2, a twist plate 4 is provided at one end of the second rod body 2, and a groove is opened at the upper end of the first rod body 1 5. The upper end of the channel 5 is provided with a screw point 7, and two quick-lock guide slide grooves 6 are symmetrically opened on the screw point 7.

[0022] Specifically, anti-slip lines 3 are provided at the lower end of the second rod body 2 and at the joint with the twist plate 4 .

[0023] Specifically, the rotation curve angle of the quick lock guide chute 6 is 180 degrees.

[0024] The present invention also provides a screw production process, comprising the steps of:

[0025] S1. Cut the wire rod into the required length, send the wire rod of this length into the first mold, and punch out the initial shape of the first rod body 1, the second rod body 2, the twist plate 4 and the screw tip 7 by cold heading;

[0026] S2...

Abstract

The invention discloses a screw and a production process thereof. The screw comprises a first rod body, a second rod body is connected to one end of the first rod body, a twisting disc is arranged atone end of the second rod body, a channel is formed in the upper end of the first rod body, a screw tip head is arranged at the upper end of the channel, two rapid locking guide sliding grooves are symmetrically formed in the screw tip head, the screw is matched with a re-buckling step in a screw nut through the rapid locking guide sliding grooves, fixing is achieved, the screw is quite convenient, the fixing effect can be achieved only by rotating 180 degrees, the screw is quite convenient, the tip head design is adopted in the screw head, compared with existing flat head design, a nut part can be rapidly aligned with the screw, the production process of the screw is high in machining precision, locking is stable, and accidental falling can be avoided.

Description

technical field [0001] The invention belongs to the field of screw manufacturing, and more specifically relates to a screw. At the same time, the invention also relates to a screw production process. Background technique [0002] The screw is a tool for tightening the parts of the object step by step by using the physical and mathematical principles of the oblique circular rotation and friction of the object. Existing screws are all fixed by the cooperation of threads. Due to the large number of threads, it is often necessary to rotate many turns when tightening to tighten, resulting in a waste of time and very inconvenient. The quick lock screws currently on the market The head is flat, it is difficult to align the nut at once, and the existing screw processing technology is not suitable for the processing of this kind of screw. Contents of the invention [0003] The purpose of the present invention is to provide a screw and its production process, so as to solve the pr...
