[0002] Marine alloy nuts usually refer to a type of alloy nut that is resistant to seawater corrosion and has high strength.

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Embodiment 1: This embodiment is intended to promote the solution of the problem that the marine environment is very harsh, with a large amount of salt spray, humid air and marine organisms. These factors will cause corrosion and erosion to marine alloy nuts, which may weaken the structural strength and corrosion resistance of the nuts, thereby causing the nut to fall off. Please refer to Figure 1-Figure 5A marine alloy nut for preventing slipping includes a nut body 100, which is set as a hexagonal nut. A bolt 200 is installed in the nut body 100. A connecting port 110 is opened in the nut body 100, and a placement cavity 120 is opened inside the nut body 100. A plurality of anti-slipping balls 121 are installed in the placement cavity 120. A through hole 130 is opened on the inner wall of the nut body 100, and the through hole 130 is connected with the placement cavity 120. Part of the anti-slipping ball 121 is located at the connecting port 110 through the through hole 130.
[0026] These balls can increase the friction between the nut and the bolt 200 to prevent the nut from slipping during use. When the anti-slipping ball 121 is in interference fit with the surface of the bolt 200, the resistance of the anti-slipping ball 121 can be increased, further enhancing the anti-slipping effect.
[0027] An internal threaded ring 111 is installed in the connection port 110, and an external threaded ring 210 is installed on the outside of the bolt 200, and the external threaded ring 210 is installed in threaded cooperation with the internal threaded ring 111. A rubber ball is provided for the anti-slipping ball 121, and when the installation nut is installed in cooperation with the outside, the anti-slipping ball 121 is interference fit with the surface of the bolt 200. A damping ring 112 is installed in the connection port 110, and the damping ring 112 is provided as two, and the two damping rings 112 are respectively located at both ends of the connection port 110, and the damping ring 112 is provided as an elastic rubber ring. By installing the internal threaded ring 111 in the connection port 110 and the external threaded ring 210 on the outside of the bolt 200, the threads of the two can cooperate with each other and be tightened to fix the parts together. A damping ring 112 is provided inside the connection port 110, and the damping ring 112 is an elastic rubber ring, which can alleviate the impact and vibration of the connection and increase the buffering performance of the nut.
[0028] When the nut and bolt 200 are connected, the threads at both ends can be tightly integrated together, thereby achieving a firm fixation of the parts. At the same time, the anti-drop ball 121 and the damping ring 112 can increase the damping between the parts and reduce the vibration when in use, preventing the parts from loosening and sliding. This design can improve the connection reliability of the nut and bolt 200, effectively reduce the failure rate of the parts, and increase the service life of the equipment.
[0029] In this embodiment, a placement cavity 120 is provided inside the nut body 100, and a plurality of anti-slipping balls 121 are installed. These anti-slipping balls 121 can increase the friction between the nut and the bolt 200 to prevent slipping. A through hole 130 is provided on the inner wall of the nut body 100, and the through hole 130 is connected to the placement cavity 120, so that the anti-slipping balls 121 can be located at the connection port 110 through the through hole 130, providing better stability and anti-slip effect.
[0030] Embodiment 2: This embodiment is intended to promote the solution of further optimization. Since the marine environment is very harsh, these factors will cause corrosion and erosion to the marine alloy nuts, which may weaken the structural strength and corrosion resistance of the nuts, thereby causing the problem of falling off.

This prevents the nut from slipping or loosening during use, thereby increasing the fixing effect of the nut. At the same time, the limiting groove and the clamping groove 220 on the outer side of the bolt 200 can keep the bolt 200 in a suitable position when rotating, further increasing the stability of the bolt 200.
[0031] There are a plurality of stoppers 141, which are distributed in a circular array along the center of the bolt 200. The internal thread ring 111 is arranged axially along the nut body 100, so that the thread of the nut is more stable and firm relative to the connecting piece.
