Description

Technical Field

[0001] The utility model belongs to a flange surface hexagon nut specifically. Background Technique

[0002] A nut, also known as a screw nut, is a fixing tool with a hole in the center and internal threads on the inner side of the hole. Nuts are often used in combination with screws of appropriate sizes to fix relevant joint parts. The most common nut is the hexagon nut.

[0003] The nut tightened on the surface of a metal object is likely to be rusted together with the metal object surface. Because the nut is rusted, when using a traditional wrench to turn it, it is easy to grind the edges and corners of the nut flat, making it difficult to unscrew the nut. Content of the Utility Model

[0004] The purpose of the utility model is to provide a flange surface hexagon nut to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A flange surface hexagon nut includes a nut body. The nut body is respectively provided with six side surfaces. A groove is opened downward in sequence from the upper surface of the nut body around the six side surfaces for one week. The grooves are six in number, and the six grooves form a plum blossom shape adapted to the socket of a wrench tool.

[0006] Preferably, a threaded hole for installing a bolt is centrally opened in the nut body.

[0007] Preferably, insertion holes are opened on the upper surface of the nut body and between every two grooves.

[0008] Preferably, a gasket for increasing friction is provided on the lower surface of the nut body.

[0009] Preferably, strip-shaped grooves are opened towards both sides in the threaded hole.

[0010] Preferably, one side of the strip-shaped groove close to the bolt insertion end is open.

[0011] Preferably, through holes are opened on the surface of the gasket, and the through holes are two in number.

[0012] Technical effects and advantages of the present utility model: For this flange surface hexagon nut, when the surface of the nut body gets rusty and the hexagon is ground flat, external insertion rods can be respectively inserted into the insertion holes opened on the upper surface of the nut body and located between two grooves. By connecting a tool to the insertion rod and rotating the insertion rod, the rotation of the nut body can be completed. At the same time, there are grooves successively opened downward from the upper surface of the nut body around the six side surfaces in a circle. Firstly, it can save the use of materials and reduce costs. Secondly, on the premise of not affecting the operation of turning with an external hexagon wrench, a special plum blossom wrench can also be used for turning operation, improving the operation convenience.

[0018] 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.

[0019] To improve the operation convenience, as shown in Figure 1 , Figure 2 and Figure 3 , the nut body 1 is respectively provided with six side surfaces 2. There are grooves 3 successively opened downward from the upper surface of the nut body 1 around the six side surfaces 2 in a circle. The number of the grooves 3 is six, and the six grooves 3 form a plum blossom shape adapted to the socket of a wrench tool. When the surface of the nut body 1 gets rusty and the hexagon is ground flat, external insertion rods can be respectively inserted into the insertion holes 5 opened on the upper surface of the nut body 1 and located between two grooves 3. By connecting a tool to the insertion rod and rotating the insertion rod, the rotation of the nut body 1 can be completed. At the same time, there are grooves 3 successively opened downward from the upper surface of the nut body 1 around the six side surfaces 2 in a circle. Firstly, it can save the use of materials and reduce costs. Secondly, on the premise of not affecting the operation of turning with an external hexagon wrench, a special plum blossom wrench can also be used for turning operation, improving the operation convenience.

[0020] To increase the ways of disassembling the nut body 1, as shown inFigure 1 , Figure 2 , Figure 3 and Figure 4 As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , a threaded hole 4 for installing a bolt is centrally provided in the nut body 1. The internal thread on the inner wall of the threaded hole 4 is adapted to the external thread on the outer side of the bolt. After rotating the nut body 1, the nut body 1 can be installed on the bolt, improving convenience. An insertion hole 5 is provided on the upper surface of the nut body 1 and between every two grooves 3. When the surface of the nut body 1 gets rusty and the hexagon is worn flat, an external insertion rod can be inserted into the insertion hole 5 provided on the upper surface of the nut body 1 and between two grooves 3. By connecting a tool to the insertion rod and rotating the insertion rod, the rotation of the nut body 1 can be completed, improving various disassembly methods of the nut body 1 and enhancing practicability. A gasket 6 for increasing friction is provided on the lower surface of the nut body 1. By means of the gasket 6, the friction with the outside is increased, making the nut body 1 more stable after installation, and the cross-section of the gasket 6 is a flange surface. Strip-shaped grooves 7 are provided on both sides in the threaded hole 4. A fixed flat screwdriver can be inserted into the strip-shaped grooves 7, or the nut body 1 can be rotated, further increasing the ways to turn the nut body 1 and improving convenience. One side of the strip-shaped groove 7 close to the insertion end of the bolt is open, and the groove 3 is an arc-shaped groove, which is more conducive to matching with a socket wrench and improving the fixing property of the socket wrench during disassembly. Through holes 8 are provided on the surface of the gasket 6, and two through holes 8 are provided. After the nut body 1 is installed, an externally inserted screw penetrates through the through holes 8, and the nut body 1 can be further fixed.

[0021] During use, first, when the surface of the nut body 1 gets rusty and the hexagon is worn flat, an external insertion rod can be inserted into the insertion hole 5 provided on the upper surface of the nut body 1 and between two grooves 3. By connecting a tool to the insertion rod and rotating the insertion rod, the rotation of the nut body 1 can be completed. At the same time, grooves 3 are provided successively downward from the upper surface of the nut body 1 around the six sides 2. Then, on the premise of not affecting the operation of turning the nut body 1 with an external hexagon wrench, a special socket wrench can also be used for turning operation to complete the disassembly of the nut body 1.

[0022] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
