Description

Technical Field

[0001] The utility model relates to the technical field of fastening nuts, in particular to a disc-shaped fastening nut. Background Technique

[0002] A fastening nut, i.e., a lock nut, is a nut applied in industries such as machinery. However, the reliability of this self-locking will decrease under dynamic loads. In some important occasions, some anti-loosening measures will be taken to ensure the reliability of the nut locking. Round nuts are often used in combination with stop washers for round nuts. During assembly, the inner tongue of the washer is inserted into the groove on the shaft, and the outer tongue of the washer is embedded into the groove of the round nut, and the nut is locked; or double nuts are used for anti-loosening. It is often used for the axial fixation of rolling bearings. Round nuts with thread specifications of M10×1~M200×3 obtain a self-locking function through design improvements on the thread structure without relying on other external factors. Therefore, their applicability is wider than the above several methods, and the requirements for the environment are relatively low. Anti-loosening nuts include many types, such as nylon nuts, and flange nuts as well. In short, such anti-loosening nuts play an anti-loosening role. When the nut is screwed onto a screw, a screw rod, a bolt, etc., it will not fall off. It enables them to be actively connected together, making them firm and stable to a very high degree.

[0003] The application number is CN201320418765.8, which discloses a fastening nut. The nut is provided with an external hexagon and an axially penetrating internal threaded hole. A flange integrally connected with the external hexagon is formed on one axial end face of the nut. The diameter of the flange is greater than the diagonal length of the external hexagon. A groove surrounding the internal threaded hole is formed on the axial end face of the flange contacting the pressed part. A plurality of triangular teeth are evenly distributed on the axial end face of the pressed part between the groove and the outer circumference of the flange. The included angle between the bottom surface of the triangular tooth and the first edge is 80~85°, the included angle with the second edge is 10~12°, and the included angle with the third edge is 5~8°. The utility model provides a fastening nut, which is simple to manufacture, convenient to use, and has wide versatility.

[0004] Although the above-mentioned utility model can be simple to manufacture, convenient to use, and have wide versatility through the settings such as the nut being provided with an external hexagon and an axially penetrating internal threaded hole, and a flange integrally connected with the external hexagon being formed on one axial end face of the nut, and the diameter of the flange being greater than the diagonal length of the external hexagon, its drawback is that when the device is stored, it cannot be disassembled conveniently, and its main body presents a fixed and complete state, and no convenient adjustment work is provided.
