Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a flange with a locking nut. Background Art

[0002] Flange is also called flange or flange. It is a part that connects pipes to each other and is connected to the pipe end. There are holes on the flange, and bolts connect the two flanges tightly. Gaskets are used to seal the flanges. Flange is a disc-shaped part, which is most common in pipeline engineering. Flanges are used in pairs. In pipeline engineering, flanges are mainly used to connect pipelines. At the ends of two pipes that need to be connected, a flange is installed on each side. Low-pressure pipelines can use threaded flanges, and pressures above 4 kg use welded flanges. Add a gasket between the two flanges and then tighten them with bolts.

[0003] After the existing flanges are connected by bolts, they are easily vibrated during subsequent use, causing the bolts used to connect the flanges to loosen, thereby reducing the connection effect.

[0004] Therefore, it is necessary to provide a flange with a locking nut to solve the above technical problems. Utility Model Content

[0005] The utility model provides a flange with a locking nut, which solves the problem that the bolts used for connecting the flanges are easily loosened due to vibration, thereby reducing the connection effect.

[0006] In order to solve the above technical problems, the utility model provides a flange with a locking nut, comprising:

[0007] A flange body, wherein the interior of the flange body is provided with a through groove;

[0008] A limiting ring, the limiting ring is fixedly mounted on the bottom of the flange body, and a limiting groove is provided on the inner side of the limiting ring;

[0009] A nut, the nut being arranged on the inner side surface of the limiting groove;

[0010] A threaded ring is threadedly connected to the outer side surface of the limiting ring, and a hexagonal block is fixedly installed on the bottom of the threaded ring.

[0011] Preferably, a rubber pad is fixedly mounted on the bottom of the inner side of the threaded ring, and the rubber pad is arranged at the bottom of the limiting ring.

[0012] Preferably, the outer side surface of the nut and the inner side surface of the limiting groove fit tightly.

[0013] Preferably, six limiting rings are provided, and the six limiting rings are respectively arranged at the bottom of the six through grooves.

[0014] Preferably, a sealing gasket is fixedly installed on the top of the flange body, and a rubber ring is fixedly installed on the bottom of the sealing gasket.

[0015] Preferably, six of the sealing gaskets and six of the rubber rings are provided, and the six rubber rings are respectively provided on the inner side surfaces of the six through grooves.

[0016] Compared with the related art, the flange with a locking nut provided by the utility model has the following advantages:

[0017] Beneficial effects:

[0018] The utility model provides a flange with an anti-loosening nut, which cooperates with each other through structures such as a limiting ring, a limiting groove, a threaded ring, a rubber pad, a hexagonal block and a nut. When using it, the user only needs to put the nut into the inner side of the limiting groove. When the bolt and the nut are threadedly connected, the user only needs to rotate the bolt without limiting the nut. The operation is convenient and quick, and the top of the rubber pad is against the bottom of the bolt, so that the bolt can be limited to avoid loosening due to subsequent use.

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the structure of a flange with a locking nut provided by the utility model; Figure 2 for Figure 1The side cross-sectional structural schematic diagram shown; Figure 3 for Figure 1 A flange with a locking nut comprises: a flange body 1, wherein the flange body 1 is provided with a through groove 11;

[0025] A limiting ring 3, wherein the limiting ring 3 is fixedly mounted on the bottom of the flange body 1, and a limiting groove 31 is provided on the inner side surface of the limiting ring 3;

[0026] A nut 5, wherein the nut 5 is arranged on the inner side surface of the limiting groove 31;

[0027] The threaded ring 4 is threadedly connected to the outer side surface of the limiting ring 3 , and a hexagonal block 42 is fixedly installed at the bottom of the threaded ring 4 .

[0028] A rubber pad 41 is fixedly mounted on the bottom of the inner side of the threaded ring 4 , and the rubber pad 41 is arranged at the bottom of the limiting ring 3 .

[0029] The outer side surface of the nut 5 and the inner side surface of the limiting groove 31 are tightly fitted.

[0030] Six limiting rings 3 are provided, and the six limiting rings 3 are respectively arranged at the bottom of the six through grooves 11 .

[0031] A sealing gasket 21 is fixedly installed on the top of the flange body 1 , and a rubber ring 2 is fixedly installed on the bottom of the sealing gasket 21 .

[0032] There are six sealing pads 21 and six rubber rings 2 , and the six rubber rings 2 are respectively arranged on the inner side surfaces of the six through grooves 11 .

[0033] By arranging the rubber ring 2 on the inner side of the through groove 11 , the bolt and the rubber ring 2 can be closely fitted together during use, thereby achieving a sealing effect.

[0034] The working principle of a flange with a locking nut provided by the utility model is as follows:

[0035] When in use, the user puts the nut 5 into the inner side of the limiting groove 31, and then the user puts the threaded ring 4 at the bottom of the limiting ring 3, and then rotates the threaded ring 4 so that the threaded ring 4 is threadedly connected to the outer side of the limiting ring 3. Then the user docks one side of the flange body 1 to be connected, and then extends the bolt through the through groove 11 to the inner side of the limiting ring 3, and then rotates the bolt so that one end of the bolt and the nut 5 are threadedly connected, thereby connecting and locking the two flange bodies 1. Then the user rotates the hexagonal block 42 with a wrench, so that the hexagonal block 42 drives the threaded ring 4 to rotate, so that the threaded ring 4 continues to be threadedly connected to the outer side of the limiting ring 3, so that the top of the rubber pad 41 is against the bottom of the bolt, thereby further limiting the bolt.

[0036] Compared with the related art, the flange with a locking nut provided by the utility model has the following advantages:

[0037] Beneficial effects:

[0038] The limiting ring 3, limiting groove 31, thread ring 4, rubber pad 41, hexagonal block 42 and nut 5 cooperate with each other. When using it, the user only needs to put the nut 5 into the inner side of the limiting groove 31. When the bolt and the nut 5 are threadedly connected, the user only needs to turn the bolt, and there is no need to limit the nut 5. The operation is convenient and quick. The top of the rubber pad 41 is against the bottom of the bolt, so as to limit the bolt and avoid loosening during subsequent use.
