The invention relates to a screw thread connection structure comprising an arc-shaped cap, a thread connecting structure and a chamfer; the arc-shaped cap is positioned at the topmost end; a prism structure is arranged below the arc-shaped cap; the prism structure and the arc-shaped cap are cast into a whole body; the thread connecting structure is cast below the prism structure; the chamfer is arranged below the thread connecting structure.
Description
technical field [0001] The invention belongs to the field of manufacturing technology, and in particular relates to a threaded connection structure. Background technique [0002] The current plugs have poor chemical resistance, are highly corroded by sewage and waste water, and are corroded by soil rotten substances. In the ultra-low temperature environment of minus 60°C, there are phenomena of freezing cracks, swelling and water leakage, and cannot adapt to different equipment specifications. Safety Sex is poor. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art and proposes a threaded connection structure, which has exquisite design, unique technology, fine processing, energy saving, noise reduction, safety and environmental protection, and reduces labor intensity. [0004] The technical solution of the present invention is: a threaded connection structure, including an arc-shaped cap, a threaded connection structure and chamfer...
