Problems solved by technology

[0002]The nut is a part that closely connects mechanical equipment, and is widely used in industry and life. The nut is one of the important connecting parts of the engine. When the engine is running, it will Continuous vibration, conventional nuts are easy to be loosened after installation, which is not conducive to the connection between various parts of the engine. After the connecting nuts between parts become loose, the engine will have a greater safety hazard. Therefore, it is necessary to propose a locking nut

Abstract

The invention discloses a locking nut. The locking nut comprises a first hexagonal tube, a second hexagonal tube, a first internal thread, sliding grooves, through holes, a third hexagonal tube, a circular ring, a first straight rod, a limiting needle, a first arc-shaped plate, a second arc-shaped plate, a second internal thread and a spring, the upper end face of said second hexagonal tube is provided with the coaxial first hexagonal tube, the lower end face of the second hexagonal tube is provided with the coaxial third hexagonal tube, the lower end face of the first hexagonal tube and the upper end face of the third hexagonal tube are parallel and symmetrical, the inner diameter of the second hexagonal tube is smaller than the inner diameter of the first hexagonal tube and the inner diameter of the third hexagonal tube, the inner tube wall of the second hexagonal tube is provided with the first internal thread, the multiple sliding grooves and the multiple through holes are axially formed in the second hexagonal tube, the sliding grooves axially penetrate through the upper end face and the lower end face of the second hexagonal tube, and the sliding grooves are formed in the inner wall of the second hexagonal tube. A sealing ring is fixed in the interior of the first hexagonal tube, so that the sealing performance of the nut can be enhanced.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, in particular to the technical field of lock nuts. 【Background technique】 [0002] Nuts are parts that tightly connect mechanical equipment. They are widely used in industry and life. Nuts are one of the important connecting parts of engines. When the engine is running, it will continue to vibrate. Conventional nuts are easy to be loosened after installation, which is not conducive to The connection between the various parts of the engine, the loose connection nut between the parts will cause the engine to have a greater safety hazard, so it is necessary to propose a lock nut. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a lock nut, which can be installed firmly, is not easy to loosen, and has a good position-limiting function. [0004] In order to achieve the above object, the present invention proposes a lock ...
