Description

Technical Field

[0001] This utility model relates to the field of nut technology, specifically a high-pressure resistant nut. Background Technology

[0002] A nut is a fastener that is screwed onto a bolt or threaded rod to secure a fastener. It's an essential component in all manufacturing machinery. Based on the material, nuts are categorized into several types, including carbon steel, stainless steel, and non-ferrous metals. Currently, wrenches are typically used to tighten nuts for a more secure connection, but existing nuts generally have poor compressive strength.

[0003] A pressure-resistant nut component, disclosed in publication number CN222823531U, includes a nut body with a threaded hole. The nut body comprises a hexagonal tightening portion and a base. A pressure-resistant shell is fitted around the outer side of the hexagonal tightening portion. The pressure-resistant shell includes a first pressure-resistant plate and a second pressure-resistant plate, with a cavity between the first and second pressure-resistant plates filled with an elastic pad. The first and second pressure-resistant plates are fixedly connected by a pressure-resistant column. A pressure-resistant pad is connected to the side of the base away from the hexagonal tightening portion. When the nut component is tightened with a wrench, the pressure-resistant shell protects the tightening portion, preventing indentations on its surface. Simultaneously, the pressure-resistant pad connected to the base prevents excessive pressure between the nut component and the connecting surface, preventing damage to the base and increasing its service life.

[0004] Existing technologies reinforce the outside of the nut to improve its compressive strength when the external knob is turned. However, when double nuts are used for locking, the internal nut (plastic part) is easily damaged by pressure. Therefore, we propose a high-pressure resistant nut. Utility Model Content

[0005] The purpose of this invention is to provide a high-pressure resistant nut to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure resistant nut, comprising a nut body, wherein the nut body has a bolt hole and an internal thread is provided at the bolt hole; a plurality of limiting holes are provided at equal intervals on the inner side of the nut body, and an anti-pressure column is installed in the limiting holes of the nut body.

[0007] Preferably, the pressure-resistant column is a cylindrical structure with an arc groove, and the shape of the side of the pressure-resistant column away from the arc groove matches the shape of the limiting hole.

[0008] Preferably, the pressure-resistant column is a stepped column structure, the middle part of the pressure-resistant column is a stepped structure, a circular arc groove is opened on one side of the pressure-resistant column, and the shape of the side of the pressure-resistant column away from the circular arc groove matches the shape of the limiting hole.

[0009] Preferably, 4-6 limiting holes and pressure-resistant columns are provided.

[0010] Preferably, there are 5 limiting holes and 5 pressure-resistant columns.

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

[0012] 1. Multiple limiting holes are evenly spaced on the inner side of the nut body. Anti-compression columns are installed in the limiting holes of the nut body. The anti-compression columns improve the compressive strength of the nut body, thereby preventing the plastic nut from being damaged due to compression.

[0013] 2. The compression column is a stepped column structure, with a stepped structure in the middle. The stepped structure gives the compression column a limiting effect in one direction. Attached Figure Description
