In order to achieve the above purpose, Guangdong Yueluo Hardware Industry Co., Ltd. discloses a tamper-proof nut, which includes an upper part, a lower part, and an inner threaded hole penetrating the upper part and the lower part. The cross section of the inner threaded hole is circular, so the The lower part is an equilateral triangle cylinder, and the apex of the equilateral triangle cylinder has an arc structure, and the arc structure includes a left arc part and a right arc part with the angle bisector as the center of symmetry, and the lower part has an arc structure. A tamper-proof portion protruding from the lower surface is formed, and the tamper-proof portion is arranged at the left arc portion or the right arc portion.

The technical solution adopted by Guangdong Yueluo Hardware Industry Co., Ltd. to solve its technical problems is a special pull rivet for railway freight cars, which has a pull rivet body and a collar. The rod body is composed of polished rod section, locking ring groove section and tail thread section from top to bottom. Protectors are provided at the tail thread section to prevent rust and bad teeth in the tail thread section during use. , collision deformation, etc. Specifically, the tail thread segment has an external thread or an internal thread, and the protective member is a nut or a bolt.

At present, with the continuous growth of the demand for communication products, higher and higher requirements are put forward for the production capacity of equipment manufacturers, and at the same time, the requirements for the cost, weight and reliability of communication products are also more and more stringent. In order to facilitate the positioning of the equipment, pins are often used to complete the equipment, and a certain cost is incurred for its manufacture and assembly. In the past, such parts have been assembled in the form of threads. In order to ensure that the assembly height is within the specified range and to prevent loosening, bar turning is often used to form threads and positioning steps, and thread pinning glue is used in the assembly, and the cost of machining is relatively high. Large, more material waste. Based on the above drawbacks, in order to better solve this problem, some existing manufacturers use the interference fit riveting method, which solves the problem of material waste and anti-loosening, but the inner diameter of the pin hole and the outer diameter of the pin are matched. The machining accuracy of the machine is relatively high. Once the matching size is out of tolerance, a second matching is required, which wastes working hours and increases the slack time.

In the modern industrial field, products such as nuts and bolts are widely used to lock structural parts, but at the same time we also find that in many cases, especially when applied to vibration, we often need to lock the already locked Structural parts are regularly repaired and strengthened to prevent structural dislocation caused by loose nuts and bolts.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: type 2 hexagon nuts, flat-tail machine screws, claw-shaped speaker wood inlaid nuts, tap screws and other products, we can provide you with products suitable for you fastener solutions.
