Blind rivets are a type of rivets for single-sided riveting, but they must be riveted with a special tool - a rivet gun (manual, electric, pneumatic). This type of rivet is especially suitable for riveting occasions where it is inconvenient to use ordinary rivets (which must be riveted from both sides), so it is widely used in construction, automobiles, ships, aircraft, machinery, electrical appliances, furniture and other products. Among them, the open type oblate head blind rivets are the most widely used, the countersunk head blind rivets are suitable for riveting occasions that require smooth performance, and the closed blind rivets are suitable for riveting occasions that require higher load and certain sealing performance.
With the advancement of technology in various industries, the current structural design of screws has evolved from just simple locking to focusing on work efficiency during the locking process and not destroying the integrity of the objects to be locked. New cases such as No. 556784 screw improvement and No. 289415 screw that integrates locking, stability, labor-saving, fast and multi-function which were previously designed and approved and published in the Central Taiwan Bulletin are the main representatives of screws. It is clear that It is learned that the two cases not only fully improve the shortcomings of the traditional simple locking screws, but also achieve the purpose of substantial improvement of the screws designed in each case in actual use.
The existing combination screws and accessories are individually processed and then handed over to the customer for assembly. This method is prone to assembly problems, and the combination screws and accessories need to be marked with identification marks, which increases the production cost.
High-strength self-locking nut for boats and bridges, it can convert the friction force into the expansion force between the bolt and the slot nut to achieve excellent self-locking effect. There are two slots on the upper part of the ESL nut. When the nut is tightened on the bolt, the thread of the bolt will be screwed into the slot of the cross section of the nut, and the thread will be gradually locked by the side wall of the nut to achieve the function of self-locking. The exquisite production process can keep the torque type of the locking element consistent, and the products are generally used in railway casting, rail transit, transmission system, mining equipment, highway, military, oil production machinery, automobile industry, public facilities, subway, engine, construction machinery , aerospace, drilling equipment, bridges, generators, agricultural machinery, shipbuilding industry, metallurgical equipment, trains, compressors, medical machinery, signal systems, wind power generation
