Abstract

The invention discloses a stop screw for mechanical equipment. The stop screw comprises a screw head, a screw rod, an auxiliary screw hole, an inner screw, a tension spring, a self-tapping auxiliary conical head, a fragmentation conical block, an opening arc groove, an arc opening section, a stop washer groove, an elastic washer, a threaded rod extrusion groove, an extrusion bolt, a stop ring groove, a stop ring piece and a limiting pyramid. The screw can achieve the stable connection effect through multiple anti-loosening structures in the connecting process, loosening and falling are not prone to occurring when the screw is used for a long time in the vibration environment of mechanical equipment, the fastening performance of screw connection is guaranteed, connection is stable and durable, safety is high, the structure is reasonable, operation is convenient, and application and popularization are facilitated.

Description

【Technical field】 [0001] The invention relates to the technical field of screws, in particular to the technical field of anti-loosening screws for mechanical equipment. 【Background technique】 [0002] The screw is a tool that uses the principle of the circular rotation of the oblique surface of the object and the principle of friction to fasten the mechanism of the object step by step. A screw is a common fastener, widely used in machinery, electrical appliances and buildings. The general material is metal or plastic, it is cylindrical, and the grooves with concave and convex on the surface are called threads. The main function of the screw is to join two. An object, or to fix an object in position, the screw can often be removed or re-tightened at will without compromising its efficiency. Generally, the diameter of the top of the screw is larger, and the common ones are round, square or regular hexagon. If the top is regular hexagon, you can turn the screw with a wrench. I...
