Product Details
M5 grounding screw used to fix the grounding wire to household appliances, etc. The screw is cylindrical and perpendicular to the end face (fracture). In the production process of equipment threaded holes, the self tapping guide groove of the sinking guide is required. Therefore, when fixing the grounding wire, if the screw is not correctly positioned (the screw is tilted), it is necessary to strongly press the screw. The screw and threaded hole are prone to meshing, and the screw will loosen after meshing
9. The waterproof oil filling cap according to claim 5, characterized in that there can be a waterproof edge 8 at the bottom end of the shell 1 that gradually increases in diameter and thins the shell wall, which is integrated with the shell 1. Abstract: This utility model is a screw waterproof oil cap, which is composed of a shell 1, a platform 2, a connecting pipe 3, small holes 4, an oil adhesive pad 5, a sponge 6, a top cover 7, and a waterproof edge 9. Due to the adoption of an oil infiltration structure, this utility model has the characteristics of convenient use, simple structure, automatic infiltration, and no need for rust removal of screws. It can be used in various occasions, especially for the protection of bolt components on railway rails.
In existing technology, spring washers have a certain anti loosening effect. However, due to the unreasonable design structure, the compatibility between the upper and lower tightening forces of the spring washer and the stopping force of the spring washer is poor, resulting in low friction between the smooth surface and the bolt head, nut, and connected parts. When the bolt or nut is subjected to strong vibration, the bolt or nut will still loosen. Therefore, The anti loosening effect of the above spring washers still needs improvement.
On the outer surface of the cylindrical body, there is a step part 6, which is an externally convex step. The outer diameter of the step part is configured with the aperture of the bottom hole of the riveting part. The specific size of the outer diameter of the step part is determined based on the actual size of the bottom hole of the riveting part that matches it, so as to form a transitional fit between the two. The step part can reduce the gap between the riveting nut column and the bottom hole of the riveting part, in order to generate greater wrapping force. The height of the step part is less than or equal to the thickness of the riveting part, ensuring that the installation size of the riveting nut column is completely consistent with that of the general riveting nut column after riveting.
A screw slotting device includes a workbench, a vibrating disc arranged on the upper part of the workbench, a conveying device arranged below the discharge port of the vibrating disc, a slotting device arranged on one side of the conveying device, a cutting wheel that can be reciprocally extended to slot the screws in the conveying device, and a fixed wheel for polishing the slotted screws.
