Abstract
Description
Technical Field
[0001] This utility model relates to the field of conversion flange technology, specifically a conversion flange that is easy to connect. Background Technology
[0002] A conversion flange is a device that converts one connection type (or specification, size) to another. If the main body of this device is a flange, it can be called a conversion flange. Correspondingly, there are conversion joints, conversion sockets, etc. Research shows that most existing conversion flanges use bolts for connection. While convenient, relying solely on bolts leads to loosening after a period of use due to external vibrations, resulting in poor performance. Therefore, designing a conversion flange that is both easy to connect and stable is essential. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides an easy-to-connect conversion flange, which solves the problem that most conversion flanges in the existing technology are basically connected by bolts. Although this is convenient, bolts alone can loosen after a period of use due to external vibrations and other factors, resulting in poor performance.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a conversion flange that is easy to connect, including a first conversion flange and a second conversion flange, the bottom end of the first conversion flange is equipped with the second conversion flange, the outer wall and the inner wall of the first conversion flange and the second conversion flange are respectively equipped with a connecting mechanism and a fixing mechanism, and a sealing ring is arranged between the first conversion flange and the second conversion flange;
[0005] The connecting mechanism includes several concave plates fixedly connected to the outer wall of the second conversion flange. A baffle is hinged to the groove of the concave plate by a pin. A locking block is engaged at the top of the baffle, and the outer wall of the locking block is fixedly connected to the first conversion flange.
[0006] Preferably, a telescopic rod is slidably connected to the groove of the baffle, one end of the telescopic rod is fixedly connected to the second conversion flange, and the other end of the telescopic rod is fixedly connected to a stop block.
[0007] Preferably, a spring is sleeved around the outer periphery of the telescopic rod, and the two ends of the spring are respectively connected to the baffle and the second conversion flange.
[0008] Preferably, the fixing mechanism includes a bolt disposed in the threaded holes of the first and second conversion flanges, a nut being threadedly connected to the bottom outer circumference of the bolt, and the top of the nut being in contact with the second conversion flange. A gasket is disposed between the bolt and the first conversion flange, and the gasket is fitted around the outer circumference of the bolt.
[0009] Preferably, a first connecting pipe is fixed to the top end of the first conversion flange.
[0010] Preferably, a second connecting pipe is fixedly connected to the bottom end of the second conversion flange.
[0011] Beneficial effects
[0012] This utility model provides a conversion flange that is easy to connect, and has the following advantages:
[0013] When this device is needed, the sealing ring can be installed between the first and second conversion flanges. Then, the first and second conversion flanges are connected. The baffle is rotated outward, causing the baffle to move the telescopic rod through the stop block. At the same time, the baffle, in conjunction with the second conversion flange, can stretch the spring, causing it to undergo elastic deformation. Then, the bolts and gaskets are installed on the first and second conversion flanges, and the nuts are tightened onto the bolts. When the first and second conversion flanges are connected to their limit positions, the baffle is released. At this time, the baffle can be reset under the elastic force of the spring, and the top of the baffle can just fit into the slot of the locking block. In this way, the first and second conversion flanges can be limited by the baffle and the locking block, so that even after a period of use, the connection is not easy to loosen. Therefore, it is not only easy to connect, but also has high stability. Attached Figure Description

The outer wall and the inner wall of the first conversion flange 1 and the second conversion flange 2 are respectively equipped with a connecting mechanism and a fixing mechanism. A sealing ring 12 is arranged between the first conversion flange 1 and the second conversion flange 2.
[0021] The connecting mechanism includes a plurality of concave plates 3 fixedly connected to the outer wall of the second conversion flange 2. A baffle 4 is hinged to the groove of the concave plate 3 by a pin. A locking block 5 is engaged at the top of the baffle 4, and the outer wall of the locking block 5 is fixedly connected to the first conversion flange 1.
[0022] A retaining block 5 is provided on the outer wall of the first conversion flange 1, and a retaining groove is machined on the retaining block 5 to facilitate the insertion of the baffle 4.

[0024] A groove is machined inside the baffle 4, so that the baffle 4 can drive the telescopic rod 6 to extend and retract through the groove.
[0025] In this embodiment, the telescopic rod 6 is further configured to have a spring 8 sleeved around its outer periphery, and the two ends of the spring 8 are respectively connected to the baffle 4 and the second conversion flange 2.
[0026] In this embodiment, the fixing mechanism is further configured such that the bolt 9 is disposed in the threaded hole of the first conversion flange 1 and the second conversion flange 2, the bottom end of the bolt 9 is threadedly connected to the nut 10, and the top end of the nut 10 is in contact with the second conversion flange 2.
