Description
Technical Field
[0001] The utility model relates to the technical field of nuts, in particular to a hexagonal nut for high-pressure and high-strength petroleum pipelines. Background Art
[0002] Hexagonal nuts are a common fastener, mainly used in conjunction with bolts and screws to achieve the function of connecting and fastening parts. They have different types, specifications, characteristics and uses, and are widely used in many fields such as construction engineering, machinery manufacturing, electronic products and home maintenance.
[0003] A nut is a fastener with an internal thread and used in conjunction with a bolt. During the installation of an oil pipeline in a high-pressure and high-strength environment, a hexagonal nut and a bolt are often used to fix the pipeline to prevent the pipeline from falling off. However, when some bolts are used, there may be some gravel and dust in the gap between the external threads. When the hexagonal nut is screwed, the internal threads inside the hexagonal nut may be worn. Therefore, a hexagonal nut for a high-pressure and high-strength oil pipeline is proposed. Utility Model Content

[0012] Preferably, a rubber pad is fixedly installed on the bottom surface of the abutting ring.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: for the hexagon nut for high-pressure and high-strength petroleum pipelines, through the setting of the cleaning assembly, the mounting plate is driven to move, so that the cleaning cotton moves. When the cleaning cotton contacts the surface of the bolt, the hexagon body is rotated to drive the cleaning cotton to rotate, so that the cleaning cotton cleans the gravel and dust on the surface of the bolt, preventing the gravel and dust from entering between the hexagon nut and the bolt, and avoiding the wear of the internal thread inside the hexagon nut. Through the setting of the rubber pad, when the hexagon nut is tightened, the rubber pad contacts the surface of the metal object, avoiding the direct contact between the abutting ring and the surface of the metal object, and can avoid the problem that the hexagon nut is difficult to unscrew caused by rust between the abutting ring and the surface of the metal object.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Embodiment: Refer toFigures 1-5 , the present utility model provides a technical solution, a hexagonal nut for high-pressure and high-strength oil pipelines, including a hexagonal body 1. An installation hole 2 is opened inside the hexagonal body 1. An inner support 4 is fixedly installed inside the installation hole 2. An installation groove 3 is opened on the bottom surface of the hexagonal body 1. An installation block 5 is fixedly installed on the bottom surface of the inner support 4. Through the arrangement of the installation groove 3 and the installation block 5, it is convenient to fix the inner support 4. An internal thread 6 is arranged inside the inner support 4. A contact ring 8 is fixedly installed on the bottom surface of the hexagonal body 1. A through hole 10 is opened inside the contact ring 8. A rubber pad 17 is fixedly installed on the bottom surface of the contact ring 8. Through the arrangement of the rubber pad 17, when tightening the hexagonal nut, the rubber pad 17 contacts the surface of the metal object, avoiding the direct contact between the contact ring 8 and the surface of the metal object, and can avoid the problem that the hexagonal nut is difficult to unscrew caused by rust between the contact ring 8 and the surface of the metal object.
[0022] Specifically, anti-slip grooves 7 are opened on the surface of the hexagonal body 1, and a plurality of groups of anti-slip grooves 7 are provided. A reinforcing member 9 is fixedly connected between the hexagonal body 1 and the contact ring 8, and the number of the reinforcing members 9 is multiple groups. Through the arrangement of the anti-slip grooves 7, the friction on the surface of the hexagonal body 1 can be increased. Through the arrangement of the reinforcing member 9, the connection strength between the hexagonal body 1 and the contact ring 8 can be enhanced.
[0023] Specifically, a cleaning component is arranged inside the contact ring 8. The cleaning component includes a threaded rod 11 rotatably installed inside the contact ring 8. A knob 12 is fixedly installed at one end of the threaded rod 11. An internal threaded cylinder 13 is threadedly installed on the surface of the threaded rod 11. An installation plate 14 is fixedly installed at one end of the internal threaded cylinder 13. A cleaning cotton 16 is fixedly installed on the other side of the installation plate 14. A limiting rod 15 is fixedly installed on one side of the installation plate 14, and the limiting rod 15 is slidably connected with the contact ring 8. Through the arrangement of the cleaning component, when rotating the knob 12, the threaded rod 11 is driven to rotate. The threaded rod 11 is threadedly connected with the internal threaded cylinder 13. As the threaded rod 11 rotates, the internal threaded cylinder 13 moves, driving the installation plate 14 to move, and the cleaning cotton 16 to move. When the cleaning cotton 16 contacts the surface of the bolt, rotate the hexagonal body 1, screw the hexagonal nut onto the bolt, and at the same time drive the cleaning cotton 16 to rotate, so that the cleaning cotton 16 cleans the gravel and dust on the surface of the bolt, preventing the gravel and dust from entering between the hexagonal nut and the bolt, and avoiding wear of the internal thread 6 inside the hexagonal nut.
[0024] The electrical components mentioned in this article are all electrically connected to the external main controller and 220V mains electricity, and the main controller can be a conventional known device such as a computer for control.
[0025] In use: When it is necessary to tighten the hexagon nut on the bolt, rotate the knob 12 to drive the threaded rod 11 to rotate. Since the threaded rod 11 is threadedly connected to the internal thread cylinder 13, as the threaded rod 11 rotates, the internal thread cylinder 13 moves, driving the mounting plate 14 to move, and the cleaning cotton 16 to move. When the cleaning cotton 16 contacts the surface of the bolt, rotate the hexagon body 1 to screw the hexagon nut onto the bolt, and at the same time drive the cleaning cotton 16 to rotate, so that the cleaning cotton 16 cleans the gravel and dust on the surface of the bolt, preventing the gravel and dust from entering between the hexagon nut and the bolt, and avoiding wear of the internal thread 6 inside the hexagon nut. Through the setting of the rubber pad 17, when tightening the hexagon nut, the rubber pad 17 contacts the surface of the metal object, avoiding the direct contact between the contact ring 8 and the surface of the metal object, and preventing the problem that the hexagon nut is difficult to unscrew due to rusting between the contact ring 8 and the surface of the metal object.
