Description

Technical Field

[0001] The utility model belongs to the technical field of hexagonal nuts, in particular to a flange hexagonal nut with anti-slip teeth. Background Art

[0002] Flange hexagon nut is a common fastener, which is characterized by a flange attached to the bottom of the hexagonal nut, which allows the nut to provide a larger contact surface during installation. Flange hexagon nut is a powerful and widely used fastener, suitable for various mechanical and structural connection requirements, and is therefore widely used in various industries.

[0003] There are still some problems in the actual use of flange hexagon nuts in the existing technology. For example, the existing flange hexagon nuts lack an anti-slip structure, which causes the nuts to loosen during long-term tightening and use, thereby causing the objects to be tightened to loosen.

[0004] Therefore, in order to solve the above problems, a flange hexagonal nut with anti-slip teeth is proposed. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve the problem that the existing flange hexagonal nut lacks an anti-slip structure, a flange hexagonal nut with anti-slip teeth is proposed.

[0006] The technical solution adopted by the present invention to solve its technical problem is: the utility model describes a flange hexagonal nut with anti-slip teeth, comprising a nut body, a flange fixedly mounted on the bottom surface of the nut body, a threaded groove provided inside the nut body, an anti-slip sheet provided on the bottom surface of the flange, a plurality of anti-slip sheets, and the plurality of anti-slip sheets are equidistantly arranged on the bottom surface of the flange, and the setting of the anti-slip sheet is used to increase the friction between the flange and the contact surface.

[0007] Preferably, the bottom surface of the anti-slip sheet is an arc-shaped structure, and the anti-slip sheet is welded to the bottom surface of the flange.

[0008] Preferably, a cavity is provided inside the nut body, the interior of the cavity is filled with protective oil, and an extrusion ring is movably engaged inside the cavity.

[0009] Preferably, a through hole is opened inside the thread groove, and the number of the through holes is multiple, and the multiple through holes penetrate into the interior of the cavity.

[0010] Preferably, a pressing ring is fixedly mounted on the top surface of the extrusion ring, and one end of the pressing ring is located outside the nut body.

[0011] Preferably, a sealing gasket is fixedly mounted on the bottom surface of the flange, the sealing gasket is located on the inner side of the anti-slip sheet, and the sealing gasket is a rubber ring.

[0012] Beneficial effects of the utility model:

[0013] The utility model provides a flange hexagonal nut with anti-slip teeth. By arranging anti-slip sheets, since a plurality of anti-slip sheets are arranged on the bottom surface of the flange, when the flange contacts the fastening surface, the anti-slip sheets and the fastening surface can fit well, thereby increasing the friction between the flange and the fastening surface, thereby improving the overall fastening effect of the device and preventing the problem of slipping.

[0014] The utility model provides a flange hexagonal nut with anti-slip teeth. A cavity is set, and a pressing ring is pressed downward to drive an extrusion ring to move downward inside the cavity. During the movement, the protective oil filled in the cavity can be squeezed into the through hole, and can flow out through the through hole to fill the gap between the thread groove and the fastening bolt, thereby providing good protection for the thread groove.

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Specific examples are given below.

[0024] See also Figure 1-Figure 4 The utility model provides a flange hexagonal nut with anti-slip teeth, including a nut body 1, a flange 2 is fixedly installed on the bottom surface of the nut body 1, a threaded groove 3 is opened inside the nut body 1, and an anti-slip sheet 4 is provided on the bottom surface of the flange 2. There are multiple anti-slip sheets 4, and the multiple anti-slip sheets 4 are equidistantly arranged on the bottom surface of the flange 2. The setting of the anti-slip sheet 4 is used to increase the friction between the flange 2 and the contact surface.

[0025] The bottom surface of the anti-slip sheet 4 is an arc-shaped structure, and the anti-slip sheet 4 is welded to the bottom surface of the flange 2 , wherein a limiting plate 9 is fixedly installed on the inner wall of the cavity 6 , which can provide a good limiting effect on the extrusion ring 8 .

[0026] During operation, the entire device is first placed on the outer surface of the fastening bolt that needs to be tightened, and then the nut body 1 is rotated under the action of the thread groove 3 to move the nut body 1 on the outer surface of the fastening bolt until the flange 2 is in contact with the fastening surface. The tightening operation is completed. Since the bottom surface of the flange 2 is provided with multiple anti-slip sheets 4, when the flange 2 contacts the fastening surface, the anti-slip sheets 4 and the fastening surface can be well fitted, thereby increasing the friction between the flange 2 and the fastening surface, thereby improving the overall fastening effect of the device and preventing slipping problems. The anti-slip sheets 4 are arranged on an inclined surface, thereby further improving the anti-slip effect.

[0027] A sealing gasket 5 is fixedly installed on the bottom surface of the flange 2. The sealing gasket 5 is located on the inner side of the anti-slip sheet 4. The sealing gasket 5 is a rubber ring. When the anti-slip sheet 4 is in contact with the fastening surface, the bottom surface of the sealing gasket 5 and the fastening surface can also be well fitted, thereby increasing the overall sealing of the device, preventing external moisture from entering, and avoiding the problem of rust on the entire device.

[0028] Further, such as Figure 1-4 As shown, a cavity 6 is provided inside the nut body 1, the interior of the cavity 6 is filled with protective oil, an extrusion ring 8 is movably clamped inside the cavity 6, a through hole 7 is provided inside the thread groove 3, and there are multiple through holes 7, and multiple through holes 7 pass through the interior of the cavity 6, a pressing ring 10 is fixedly installed on the top surface of the extrusion ring 8, and one end of the pressing ring 10 is located outside the nut body 1.

[0029] During operation, after the device is tightened as a whole, the pressing ring 10 is pressed downward to drive the extrusion ring 8 to move downward inside the cavity 6. During the movement, the protective oil filled in the cavity 6 can be squeezed into the through hole 7 and can flow out through the through hole 7 to fill the gap between the thread groove 3 and the fastening bolt, thereby providing good protection for the thread groove 3 and increasing the sealing between the fastening bolt and the thread groove 3, which can effectively prevent rust from occurring between the thread groove 3 and the fastening bolt. The protective oil can be some commonly used liquids such as engine oil and lubricating oil.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
