Screw structure with adhesive layer and coating method of screw structure

Abstract

The invention provides a screw structure with an adhesive layer and a coating method of the screw structure. The screw structure is mainly formed by assembling a screw head and a screw part, wherein one end of the screw part is assembled with the screw head, and the screw part comprises a plurality of thread lines and a plurality of non-slip layers; the multiple thread lines are wound on the periphery of the screw part, and are coiled from the junction of the screw head and the screw part to the other end of the screw part; the multiple non-slip layers are coated on the multiple thread lines at a cross angle formed by a first angle, a second angle and a third angle; and the screw part is provided with a central line which extends downwards from the center of the screw head to the bottom ofthe screw part. By utilizing the non-slip layers coated on a screw, the optimal non-slip effect is achieved by calculating the coating angle of the non-slip layers and the screw.

Description

technical field [0001] The present invention relates to a screw structure with an adhesive layer and its coating method, especially to an anti-slip layer coated on the screw, and to calculate the angle between the anti-slip layer and the screw coating to achieve the best anti-slip effect. Background technique [0002] Generally speaking, a screw is an important component that can be regarded as a lockable part. However, due to the small size of the screw, when using it in different occasions, it is necessary to consider the tension, bearing force, loosening prevention, and locking balance. When one of the When there is a problem in the link, it will definitely cause great damage to the assembled product. Therefore, most of the existing screw products have an anti-slip coating. However, the past coating has not been professionally compared or calculated. Coat the screw, but apply an anti-slip coating on the screw at will, so that there will be local anti-slip, and anti-slip ...

[0002] Generally speaking, a screw is an important component that can be regarded as a lockable part. However, due to the small size of the screw, when using it in different occasions, it is necessary to consider the tension, bearing force, loosening prevention, and locking balance. When one of the When there is a problem in the link, it will definitely cause great damage to the assembled product. Therefore, most of the existing screw products have an anti-slip coating. However, the past coating has not been professionally compared or calculated. Coat the screw, but apply an anti-slip coating on the screw at will, so that there will be local anti-slip, and anti-slip that cannot be symmetrically hard, which will easily cause the screw to be unable to lock evenly, and even the screw will be tilted when the bolt is screwed. There is also an anti-slip coating that is fully coated on the screw, but the cost is relatively high

[0003] Please refer to Figure 1 to Figure 4 As shown, the known screw structure is generally equipped with a screw A with an anti-slip coating B, such as figure 2 As shown, the anti-slip coating B is on the whole of a screw part C. Since the anti-slip coating B cannot be evenly applied on the screw part C, it is easy to cause the screw A to be screwed smoothly and locking, and the cost of such anti-slip coating B is relatively high, another example image 3 and Figure 4 As shown, the anti-slip coating B is applied vertically on the screw part C, but due to the direction of the screw A when the screw is screwed, it cannot be effectively evenly distributed on the locked part during locking
