Description

Technical Field

[0001] The utility model relates to the technical field of nut technology, and specifically relates to a self-reinforcing anti-loosening flange nut. Background Art

[0002] A nut is a part that is screwed together with a bolt or screw for fastening. It is a component that must be used in all manufacturing machinery. According to the different materials, it is divided into several major types, such as carbon steel, stainless steel, non-ferrous metals (such as copper), etc.

[0003] Nuts are parts that tightly connect mechanical equipment. Nuts and bolts of the same specifications can be connected together through the inner thread. For example, M4-P0.7 nuts can only be connected with M4-P0.7 series bolts (in nuts, M4 refers to the inner diameter of the nut is about 4mm, and 0.7 refers to the distance between two thread teeth is 0.7mm); the same is true for American products, for example, 1 / 4-20 nuts can only be matched with 1 / 4-20 screws (1 / 4 refers to the inner diameter of the nut is about 0.25 inches, and 20 refers to 20 teeth in every inch). They can be divided into self-locking nuts, anti-loosening nuts, locking nuts, four-claw nuts, screw-in nut insurance nuts, thin-rod screw connection nuts, self-locking hexagonal cap nuts, special nuts for anchor screws, hexagonal crown thin nuts, and eye nuts. They are easy to install, do not require washers, are easy to disassemble, are reusable, are made of medium carbon steel, and can be used with grade 8.8, grade 10.9 and other high-strength bolts.

[0004] During the specific use of the nut, the nut is screwed onto the bolt with a strong screwing force to fix it. However, when used for a long time or when vibration occurs, the nut will become loose and fall off, which has a huge impact on the overall structure of the fixed part. After loosening, gaps will appear, and the gaps will become larger and larger. Rust and corrosion will occur inside the gaps, posing a major safety hazard. In view of this, a self-reinforcing and anti-loosening flange nut is developed. Utility Model Content

[0005] The utility model proposes a self-reinforcing anti-loosening flange nut, which solves the problem in the related technology that the nut will become loose and fall off when used for a long time or when vibration occurs, which has a huge impact on the overall structure of the fixed part. After loosening, gaps will be generated, and the gaps will become larger and larger, causing rust and corrosion inside the gaps, posing a major safety hazard.

[0010] The screw connection assembly includes an internal thread, which is arranged on the inner wall of the hexagonal nut. The inner wall of the hexagonal nut is provided with a fixed clearance groove. The number of the fixed clearance grooves is two, and the fixed clearance grooves are opened at two opposite ends of the inner side of the hexagonal nut. The bottom of the hexagonal nut is provided with an annular cavity, and a tight pad is embedded in the annular cavity.

[0011] As a further technical solution, an embedding ring is provided on the tight pad, a through hole is opened on the upper end surface of the embedding ring, and a clearance hole is provided on the outer side wall of the through hole.

[0012] As a further technical solution, the transverse locking assembly includes a screw hole, which is opened on the side wall of the hexagonal nut. The screw hole is connected to a drive hole, which is opened on the side wall of the hexagonal nut. A sealing buckle cover is connected to the pin shaft inside the drive hole.

[0013] As a further technical solution, the size, position and shape of the clearance hole and the fixed clearance groove are the same.

[0014] As a further technical solution, the inner side wall of the sealing buckle cover is provided with an opening cavity, the side wall of the sealing buckle cover is provided with an extension plate, and the opposite side walls of the extension plate are provided with connecting pins.

[0027] like Figure 1~Figure 4 As shown, this embodiment provides a self-reinforcing anti-loosening flange nut, comprising

[0028] A hexagonal nut 1, wherein arc surfaces 2 are arranged at the edges of the upper and lower sections of the hexagonal nut 1;

[0029] A screw connection assembly 3, which is arranged on the inner side of the hexagonal nut 1;

[0030] A transverse locking component 4, which is arranged on the side wall of the hexagonal nut 1;

[0031] The screw connection assembly 3 includes an internal thread 3-1, which is arranged on the inner wall of the hexagonal nut 1. The inner wall of the hexagonal nut 1 is provided with a fixed clearance groove 3-2. The number of the fixed clearance grooves 3-2 is two. The fixed clearance grooves 3-2 are opened at the opposite ends of the inner side of the hexagonal nut 1. The bottom of the hexagonal nut 1 is provided with an annular cavity 3-3, and a tight pad 3-4 is embedded in the annular cavity 3-3.

[0032] In this embodiment, the internal thread 3-1 is used to screw the bolt, and the fixed clearance groove 3-2 retains a gap when the hexagonal nut 1 is in use. The arc surface 2 provides the hexagonal bolt with smoother edges and corners, and soft fitting is performed through the clamping pad 3-4 to prevent scratches on the plane from damaging the hexagonal nut 1.

[0033] Specifically, an embedding ring 3-5 is provided on the close pad 3-4, a through hole 3-6 is opened on the upper end surface of the embedding ring 3-5, and a clearance hole 3-7 is provided on the outer side wall of the through hole 3-6.

[0034] In this embodiment, the embedding ring 3-5 is used to be embedded in the annular cavity 3-3 for connection, and the through hole 3-6 and the clearance hole 3-7 are used in conjunction with the hexagonal nut 1.

[0035] Furthermore, the transverse locking assembly 4 includes a screw hole 4-1, which is opened on the side wall of the hexagonal nut 1. The screw hole 4-1 is connected to a drive hole 4-2, which is opened on the side wall of the hexagonal nut 1. The inner pin of the drive hole 4-2 is connected to a sealing buckle cover 4-3.

[0036] In this embodiment, the sealing buckle cover 4-3 is used to seal the drive hole 4-2 and the screw hole 4-1 to prevent rust. After the spiral or screw is screwed into the drive hole 4-2, it enters the screw hole 4-1 and presses against the bolt screwed by the internal thread 3-1.

[0037] Furthermore, the size, position and shape of the clearance hole 3-7 and the fixed clearance groove 3-2 are the same, the inner wall of the sealing buckle cover 4-3 is provided with an opening cavity 4-4, the side wall of the sealing buckle cover 4-3 is provided with an extension plate 4-5, and the opposite side walls of the extension plate 4-5 are provided with connecting pins 4-6.

[0038] In this embodiment, the opening cavity 4-4 facilitates opening the sealing buckle cover 4-3, and the connecting pin 4-6 on the extension plate 4-5 is used for connection, so that the sealing buckle cover 4-3 is movably connected and can be turned over.

[0039] Furthermore, the outer contour of the locking pad 3-4 is circular, the locking pad 3-4 fits on the hexagonal nut 1, the driving hole 4-2 and the sealing buckle cover 4-3 are both circular structures, the sealing buckle cover 4-3 is embedded in the driving hole 4-2, and screw holes 4-1 are opened on two opposite surfaces of the outer wall of the hexagonal nut 1.

[0040] When the hexagonal nut 1 is needed to lock the bolt, the hexagonal nut 1 is screwed. After being screwed to the specified position, the sealing buckle cover 4-3 is opened and the bolt is inserted into the drive hole 4-2 and screwed laterally to provide a lateral top force to achieve a fixing effect. The fixed clearance groove 3-2 can be injected with lubricating liquid or rust removal liquid when the hexagonal nut 1 is disassembled and during daily maintenance.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
