Description

Technical Field

[0001] This utility model relates to the field of hexagonal nut technology, specifically a shock-resistant and fatigue-resistant hexagonal nut. Background Technology

[0002] Nuts are parts that tightly connect mechanical equipment and are used in various industries such as transportation, casting, shipbuilding, and wind power generation. Depending on the different needs of different industries, nuts come in different types, materials, and standards. In existing technology, nuts have poor resistance to shock and loosening and fatigue. They are installed and fixed through threaded engagement, but under external vibration, the threads are prone to loosening, which to some extent affects the firmness and stability of the installation. To address the above issues, we will carry out technical innovation based on the existing hexagonal nuts. Utility Model Content

[0003] The purpose of this invention is to provide a shock-resistant and fatigue-resistant hexagonal nut to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a shock-resistant and fatigue-resistant hexagonal nut, comprising:

[0005] A hexagonal nut, wherein a set of pressure rings is provided on both the upper and lower sides of the hexagonal nut, and a set of anti-slip pads is provided on the opposite sides of the two sets of pressure rings. An anti-slip ring is provided on the inner side wall of the anti-slip pads and is located on the inner side wall of the hexagonal nut. Reinforcing plates are evenly provided on the outer side wall of the hexagonal nut and are evenly distributed between the two sets of pressure rings.

[0006] Preferably, the two sets of anti-slip pads are provided with a first anti-slip texture evenly on opposite sides, and the inner wall of the anti-slip ring is provided with a second anti-slip texture evenly.

[0007] Preferably, the anti-slip pad and anti-slip ring are integrally molded by injection molding, the hexagonal nut and connecting ring are integrally molded, and the reinforcing plate and connecting column are integrally molded.

[0008] Preferably, a set of connecting rings is provided on both the upper and lower sides of the hexagonal nut, and a set of connecting posts is provided on both the upper and lower sides of the reinforcing plate.

[0009] Preferably, each of the two sets of pressure rings has a set of annular grooves on its opposite sides, and each of the two sets of pressure rings has a set of insertion holes evenly distributed on its opposite sides.

[0010] Preferably, the connecting ring is fixedly inserted into the annular groove, and the connecting post is fixedly inserted into the insertion hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model strengthens the surface of the hexagonal nut by reinforcing the reinforcing plate, thereby improving the fatigue resistance of the hexagonal nut. The first anti-slip pattern on the anti-slip pad can increase the adhesion stability between the hexagonal nut and the object surface. At the same time, the anti-slip ring will fit tightly with the bolt. In conjunction with the second anti-slip pattern of the anti-slip ring, the friction between the hexagonal nut and the bolt can be increased, thereby improving the installation stability of the hexagonal nut in a vibration environment.

[0013] The connecting ring increases the contact area between the hexagonal nut and the pressure ring, while the connecting post increases the contact area between the reinforcing plate and the pressure ring, thereby improving the overall stability of the bolt and thus its reliability.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3A type of earthquake-resistant and fatigue-resistant hexagonal nut includes a hexagonal nut 14. A set of pressure rings 1 are fixedly installed on both the upper and lower sides of the hexagonal nut 14. A set of anti-slip pads 12 are fixedly installed on the opposite sides of the two sets of pressure rings 1. An anti-slip ring 13 is fixedly installed on the inner wall of the anti-slip pad 12, and the anti-slip ring 13 is fixedly installed on the inner wall of the hexagonal nut 14. Reinforcing plates 11 are evenly fixedly installed on the outer wall of the hexagonal nut 14, and are evenly installed between the two sets of pressure rings 1. First anti-slip patterns are evenly formed on the opposite sides of the two sets of anti-slip pads 12, and second anti-slip patterns are evenly formed on the inner wall of the anti-slip ring 13. The reinforcing plates 11 strengthen the outer surface of the hexagonal nut 14, thereby improving its fatigue resistance. When the hexagonal nut 14 is fixed to the surface of an object by bolts, the first anti-slip patterns on the anti-slip pads 12 increase the stability of the fit between the hexagonal nut 14 and the object surface, while the anti-slip ring 13 fits tightly with the bolt. The second anti-slip groove of the anti-slip ring 13 increases the friction between the hexagonal nut 14 and the bolt, thereby improving the installation stability of the hexagonal nut 14 under vibration. The anti-slip pad 12 and the anti-slip ring 13 are injection molded as a single piece, as are the hexagonal nut 14 and the connecting ring 2, the reinforcing plate 11 and the connecting post 21. A set of connecting rings 2 are fixedly installed on both the upper and lower sides of the hexagonal nut 14, and a set of connecting posts 21 are fixedly installed on both the upper and lower sides of the reinforcing plate 11. A set of annular grooves is opened on the opposite sides of the two sets of pressure rings 1, and a set of insertion holes is evenly opened on the opposite sides of the two sets of pressure rings 1. The connecting rings 2 are fixedly inserted into the annular grooves, and the connecting posts 21 are fixedly inserted into the insertion holes. The connecting rings 2 increase the contact area between the hexagonal nut 14 and the pressure rings 1, and the connecting posts 21 increase the contact area between the reinforcing plate 11 and the pressure rings 1, thereby improving the overall stability of the bolt and thus improving its reliability.

[0020] Working principle: The hexagonal nut 14 is reinforced by the reinforcing plate 11 to improve its fatigue resistance. After the hexagonal nut 14 is fixed to the surface of the object by bolts, the first anti-slip texture on the anti-slip pad 12 increases the stability of the hexagonal nut 14 in contact with the surface of the object. At the same time, the anti-slip ring 13 fits tightly with the bolt. With the second anti-slip texture of the anti-slip ring 13, the friction between the hexagonal nut 14 and the bolt can be increased, thereby improving the installation stability of the hexagonal nut 14 in a vibration environment. The connecting ring 2 increases the contact area between the hexagonal nut 14 and the pressure ring 1, and the connecting post 21 increases the contact area between the reinforcing plate 11 and the pressure ring 1, thereby improving the overall stability of the bolt and thus improving its reliability.
