Problems solved by technology

[0004] The inventor believes that the traditional screw fixation is easy to cause the screw to reversely rotate and loosen when it is used for a long time, especially on objects that often vibrate, resulting in loosening between the connected objects, thus making the connection stability of the screw poor.

Embodiment Construction

[0040] The following is attached Figure 1-3 The application is described in further detail.

[0041] The embodiment of the present application discloses a special anti-loosening structural screw.

[0042] refer to figure 1 The anti-loosening special structure screw includes an integrally formed screw 1 and a nut 2. The circumferential side wall of the screw 1 is provided with a self-tapping thread 11, and the screw 1 is provided with a plurality of through grooves 21 through the self-tapping thread 11. Three grooves 21 are provided along the length direction of the screw 1, and the end surface of the nut 2 facing the screw 1 is also provided with a through groove 21, the through groove 21 on the nut 2 communicates with the through groove 21 on the screw 1.

[0043] refer to figure 1 , the through groove 21 is arranged obliquely in the direction away from the self-tapping thread 11 screwed in, and the notch of the through groove 21 is tapered along the axial direction close...

Abstract

The invention relates to the technical field of fastening structures, in particular to an anti-loose screw of a special structure and a machining process thereof, and relates to the technical field of fastening structures, the anti-loose screw comprises a screw rod and a nut connected to one end of the screw rod, self-tapping threads are arranged on the screw rod, a through groove penetrating through the self-tapping threads is formed in the screw rod, and a groove opening of the through groove is obliquely formed in the circumferential direction of the screw rod. The machining process comprises the steps of screw arrangement, screw clamping and positioning, through groove machining, self-tapping thread machining, cleaning and continuous machining, the screw with the through groove and the self-tapping thread is formed through the machining device, the effect that screwing-in is easy and screwing-out is difficult is achieved, the contact area of objects such as wood and the like and the screw is increased, and the machining efficiency is improved. Therefore, the screw has the advantage that the stability of the screw in threaded connection with the two objects is enhanced.

Description

technical field [0001] The present application relates to the technical field of fastening structures, in particular to an anti-loosening special structural screw and its processing technology. Background technique [0002] At present, screw is a kind of common fastener, which is mainly used to fasten two or more objects, and is widely used in the connection of machinery, electrical appliances and buildings. [0003] The traditional screw has a nut at one end and a threaded rod at the other end, and is used with a washer or a nut. After the rod is screwed into the object by rotation, two or two screws are screwed together through the thread or nut on the screw. Fix more than one object. [0004] The inventor believes that the traditional screw fixation is easy to cause the screw to reversely rotate and loosen when it is used for a long time, especially on objects that often vibrate, resulting in loosening between the connected objects, thus making the connection stability o...
