[0002] Flange, also known as flange, is just a general term. It usually refers to a disc-shaped metal body with several fixed holes around it for connecting other things. This thing is widely used in machinery, so its appearance is also strange, as long as it looks like it, it is called a flange; flange is also called flange or flange, which is a part that connects pipes to each other, connected to the pipe end, generally used in pairs. Flange connection is easy to use, can withstand greater pressure, and is widely used in industrial pipelines.
[0003] The prior art has the following problems:
[0004] 1. The existing flange has limited connection stability, which is not particularly ideal. This also leads to the problem that the flange is prone to loosening at the connection as the flange is used for a long time, which indirectly reduces the use effect of the flange and is inconvenient to promote;
[0005] 2. The existing flange does not have the function of shock absorption. When the flange is hit from the top by a heavy object from the outside, the huge shock will cause the welding point between the flange and the pipeline to loosen, resulting in leakage at the connection between the two pipelines, indirectly increasing the maintenance cost and failing to meet the use requirements. Utility Model Content
[0006] In view of the deficiencies in the prior art, the utility model provides a stable flange, which solves the problem that the stability of the existing connection is limited and not particularly ideal, which also causes the flange to become loose at the connection as the use time increases, and has no shock-absorbing function. When the flange is hit from the top by a heavy object from the outside, the huge shock will cause the welding point between the flange and the pipeline to loosen, thereby causing leakage at the connection between the two pipelines.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stable flange, comprising a flange body, a fixing hole is opened on one side of the top of the flange body, a connecting rod is arranged inside the fixing hole, a positive thread is arranged above the outer surface of the connecting rod, a positive locking nut is arranged on the outer surface of the positive thread of the connecting rod, a rubber sealing sleeve is arranged in the middle of the outer surface of the connecting rod, a reverse thread is arranged below the outer surface of the connecting rod, a reverse locking nut is arranged on the outer surface of the reverse thread of the connecting rod, and a shock absorbing component is arranged on the outer edge of the flange body;
[0008] The shock absorbing assembly includes a sleeve, an elastic ball is arranged inside the sleeve, a limiting block is arranged on one side of the elastic ball, a damping rod is arranged on one side of the limiting block, a compression spring is arranged on the outer surface of the damping rod, and an annular protective plate is arranged at one end of the damping rod.
[0009] As a preferred technical solution of the present utility model, the size of the forward locking nut and the size of the reverse locking nut are respectively matched with the size of the forward thread and the size of the reverse thread.
[0010] As a preferred technical solution of the utility model, the rubber sealing sleeve is installed on the connecting rod by bonding.
[0011] As a preferred technical solution of the utility model, there are several groups of elastic balls, and the elastic balls are arranged in a rectangular array.
[0012] As a preferred technical solution of the utility model, the size of the limit block is matched with the size of the sleeve.
[0013] As a preferred technical solution of the utility model, the compression spring is installed on the sleeve by welding.
[0014] As a preferred technical solution of the utility model, the size of the annular protective plate is matched with the size of the flange body.
[0015] Compared with the prior art, the utility model provides a stable flange with the following beneficial effects:
[0016] 1. This kind of stable flange is provided with a flange body, a fixing hole, a connecting rod, a forward thread, a forward locking nut, a rubber sealing sleeve, a reverse thread and a reverse locking nut. When connecting, the rubber sealing sleeve is first used to improve the stability of the connection between the fixing hole and the connecting rod, and then the forward locking nut and the reverse locking nut are respectively threadedly connected with the forward thread and the reverse thread on the connecting rod to form an interlocking structure, which further strengthens the stability of the connection between the two sets of flange bodies, making the connection difficult to fall off or loose. This design avoids the problem that the connection of the flange is prone to loosening as the use time increases, indirectly improves the use effect of the flange, and is easy to promote.
[0017] 2. This stable flange is provided with a shock-absorbing component, a sleeve, an elastic ball, a limit block, a damping rod, a compression spring and an annular protective plate. When the flange is hit from the top by an external heavy object, the flange body is first protected by the annular protective plate, and then the compression spring is squeezed by the annular protective plate, thereby driving the limit block to squeeze the elastic ball. At the same time, the elastic force of the elastic ball and the compression spring reacts to the annular protective plate, weakening and reducing the impact force and vibration amplitude generated by the collision, thereby improving the shock-absorbing effect of the flange. This design enables the flange to have a shock-absorbing function, and avoids the problem that when the flange is hit from the top by an external heavy object, the huge shock will cause the welding point between the flange and the pipeline to loosen, thereby causing leakage at the connection between the two pipelines, indirectly reducing the maintenance cost and meeting the use requirements.

[0025] In this embodiment, the size of the forward locking nut 5 and the size of the reverse locking nut 8 are respectively matched with the size of the forward thread 4 and the size of the reverse thread 7, so that the forward locking nut 5 and the reverse locking nut 8 are respectively threadedly connected with the forward thread 4 and the reverse thread 7 on the connecting rod 3 to form an interlocking structure, further strengthening the stability of the connection between the two sets of flange bodies 1, so that the connection is not easy to fall off or loose; the rubber sealing sleeve 6 is installed on the connecting rod 3 by bonding, so that the rubber sealing sleeve 6 is set to improve the stability of the connection between the fixing hole 2 on the flange body 1 and the connecting rod 3; the number of elastic balls 902 is several groups, and the elastic balls 9 02 are arranged in a rectangular array, so that the elastic force of the elastic ball 902 can be used to weaken the impact force and vibration amplitude generated by the collision, thereby improving the shock absorption effect of the flange; the size of the limit block 903 is compatible with the size of the sleeve 901, so that the damping rod 904 can be limited by the limit block 903 to prevent it from escaping from the inside of the sleeve 901; the compression spring 905 is installed on the sleeve 901 by welding, so that the compression spring 905 can be limited to improve the stability of the compression spring 905; the size of the annular protective plate 906 is compatible with the size of the flange body 1, so that the flange body 1 can be protected by the annular protective plate 906 when it is hit from the top by an external heavy object.
[0026] The working principle and use process of the utility model are as follows: when connecting, firstly, the stability of the connection between the fixing hole 2 on the flange body 1 and the connecting rod 3 is improved by setting the rubber sealing sleeve 6, and then the positive locking nut 5 and the reverse locking nut 8 are respectively threadedly connected with the positive thread 4 and the reverse thread 7 on the connecting rod 3 to form an interlocking structure, which further strengthens the stability of the connection between the two groups of flange bodies 1, making it difficult for the connection to fall off or loosen. This design avoids the problem that the connection of the flange is easy to loosen as the use time increases. When the flange is hit from the top by a heavy object from the outside, the annular protective plate 906 in the shock absorbing assembly 9 is first used to tighten the flange. The flange body 1 is protected, and the compression spring 905 on the outer surface of the damping rod 904 is squeezed through the annular protective plate 906, which in turn drives the limit block 903 connected to the damping rod 904 to squeeze the elastic ball 902 in the sleeve 901. At the same time, the elastic force of the elastic ball 902 and the compression spring 905 reacts to the annular protective plate 906, weakening and reducing the impact force and vibration amplitude generated by the collision, thereby improving the shock absorption effect of the flange. This design enables the flange to have a shock absorption function, avoiding the problem that when the flange is hit from the top by an external heavy object, the huge shock will cause the welding point between the flange and the pipeline to loosen, thereby causing leakage at the connection between the two pipelines.
