Description

An easy-to-install flange Technical Field

[0001] This utility model relates to the field of flange technology, and in particular to a flange that is easy to install. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts to each other, and is used for connecting pipe ends; flanges are also used on equipment inlets and outlets for connecting two pieces of equipment.

[0003] Flange connection is to fix two pipes, fittings or equipment to a flange plate, then put a flange gasket between the two flange plates and tighten them together with bolts to complete the connection. However, the current flange has the following disadvantages: (1) The left and right flanges are connected by bolts, but the bolts are separate from the flanges. It is inconvenient to find nuts during installation; (2) Adjacent flanges are only connected by bolts. After long-term use, the bolts are easy to loosen, resulting in unstable connection and reduced sealing. Therefore, we propose a flange that is easy to install to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a flange that is easy to install, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An easy-to-install flange includes two pipes, each pipe having a flange plate connected to one end. Each flange plate has an mounting assembly attached to its outer surface, each mounting assembly including an arc-shaped through groove. Each flange plate has a set of fixed grooves on its outer surface. A set of T-shaped positive and negative screws is provided on the outside of one flange plate. Two L-shaped locking blocks are threaded onto the outer surface of each T-shaped positive and negative screw. A set of sliding tubes is connected to the outer surface of one flange plate. A T-shaped fixed rod is slidably connected to the inner wall of each sliding tube. An L-shaped limiting plate is connected to the outer surface of each T-shaped fixed rod. A telescopic spring is fitted onto the outer surface of each T-shaped fixed rod. A locking groove is provided on one side of each T-shaped positive and negative screw.

[0007] In a further embodiment, each of the pipes has a circular connecting block attached to its outer surface, and one side of each circular connecting block is connected to one side of a flange.

[0008] In a further embodiment, a sealing ring is connected to one side of one of the flanges, and each of the L-shaped locking blocks is adapted to a fixed groove.

[0009] In a further embodiment, one end of each of the telescopic springs is connected to one side of the L-shaped limiting plate, and one end of each of the telescopic springs is connected to one side of the slide tube.

[0010] In a further embodiment, each of the T-shaped positive and negative screws is adapted to the arc-shaped through groove, and each of the slots is adapted to the L-shaped limiting plate.

[0011] In a further embodiment, a circular sealing extension plate is connected to one side of one of the flanges, and a circular sealing groove is formed on one side of another flange, wherein the circular sealing extension plate is adapted to the circular sealing groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device provides power by rotating a T-shaped positive and negative screw, and is connected to the T-shaped positive and negative screw by an L-shaped locking block. The L-shaped locking block is adapted to the fixed groove, which can quickly connect the two flanges and improve installation efficiency.

[0014] This device uses a T-shaped fixed rod and a sliding tube for sliding connection. The rebound force of the telescopic spring and the L-shaped limiting plate are adapted to the slot, which can easily limit the T-shaped forward and reverse screws, preventing them from loosening, reversing, or becoming misaligned during long-term use, thus improving the functionality of the device.

[0024] Please refer to Figures 1-5. In this utility model, an easy-to-install flange includes two pipes 1, each pipe 1 having a flange 2 connected to one end. Each flange 2 has an mounting assembly 3 connected to its outer surface. Each mounting assembly 3 includes an arc-shaped through groove 301. Each flange 2 has a set of fixed grooves 302 on its outer surface. A set of T-shaped positive and negative screws 304 are provided on the outside of each flange 2. Each T-shaped positive and negative screw 304 has two L-shaped locking blocks 303 threadedly connected to its outer surface. A set of sliding tubes 305 are connected to the outer surface of each flange 2. Each sliding tube 305 has a T-shaped fixed rod 306 slidably connected to its inner wall. Each T-shaped fixed rod 306 has an L-shaped limiting plate 307 connected to its outer surface. The outer surface of the fixed rod 306 is fitted with a telescopic spring 308. Each T-shaped positive and negative screw 304 has a slot 309 on one side. Power is provided by rotating the T-shaped positive and negative screw 304, and it is threadedly connected to the T-shaped positive and negative screw 304 with the L-shaped locking block 303. The L-shaped locking block 303 is adapted to the fixed slot 302, which can quickly connect the two flanges 2 and improve the installation efficiency. The T-shaped fixed rod 306 is slidably connected to the slide tube 305. The rebound force of the telescopic spring 308 and the L-shaped limiting plate 307 are adapted to the slot 309, which can conveniently limit the T-shaped positive and negative screw 304 and prevent it from loosening, reversing or misaligning during long-term use, thus improving the functionality of the equipment.

[0025] Each pipe 1 has a circular connecting block 4 connected to its outer surface. One side of each circular connecting block 4 is connected to one side of the flange 2. The circular connecting block 4 can improve the connection between the flange 2 and the pipe 1. One side of the flange 2 is connected to a sealing ring 7. Each L-shaped locking block 303 is adapted to the fixed groove 302. The sealing ring 7 can improve the sealing performance after the two flanges 2 are connected. One end of each telescopic spring 308 is connected to one side of the L-shaped limiting plate 307. One end of each telescopic spring 308 is connected to one side of the slide tube 305, which can make the L-shaped limiting plate 307 automatically reset.

[0026] Each T-shaped positive and negative screw 304 is adapted to the arc-shaped through groove 301, and each slot 309 is adapted to the L-shaped limiting plate 307. This can improve the efficiency of the connection between the two flanges 2. A circular sealing extension plate 5 is connected to one side of one flange 2, and a circular sealing groove 6 is opened on one side of another flange 2. The circular sealing extension plate 5 is adapted to the circular sealing groove 6. By using the circular sealing extension plate 5 and the circular sealing groove 6, the sealing performance of the flange 2 can be further increased.

[0027] The working principle of this utility model is as follows:

[0028] First, bring the two flanges 2 close together and align the L-shaped locking block 303 with the fixed groove 302. Then, rotate the T-shaped positive and negative screws 304, which are threadedly connected to the L-shaped locking block 303. This allows the L-shaped locking block 303 to connect and fix the two flanges 2, and also allows the circular sealing extension plate 5 to be inserted into the circular sealing groove 6. Next, stretch the T-shaped fixed rod 306 and slide it with the slide tube 305. This allows the telescopic spring 308 to extend. Slightly rotate the T-shaped fixed rod 306, aligning the L-shaped limiting plate 307 with the groove 309. Then, release the T-shaped fixed rod 306. The rebound force of the telescopic spring 308 allows the L-shaped limiting plate 307 to be inserted into the groove 309 to limit the T-shaped positive and negative screws 304. This is the complete usage process of this utility model.
