Description

Technical Field

[0001] This utility model relates to the field of flange technology, specifically to a flange with an anti-detachment structure. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts, specifically for connecting pipe ends. Flanges are also used on equipment inlets and outlets for connecting two pieces of equipment, such as gearbox flanges. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolts forming a combined sealing structure. Pipe flanges refer to flanges used for piping in pipeline systems, while equipment flanges refer to the inlet and outlet flanges of the equipment. Flanges have holes, and bolts are used to tightly connect two flanges. A gasket is used for sealing between flanges. Flanges are classified as threaded (screw-connected) flanges, welded flanges, and clamp flanges. Flanges are always used in pairs. Low-pressure pipelines can use threaded flanges, while welded flanges are used for pressures above four kilograms. A gasket is placed between two flange plates, and then bolts are used to tighten them. Currently, flanges are generally used in pairs, fixed together with multiple bolts. Bolt installation presents many problems: firstly, installation efficiency is low; secondly, rusting makes disassembly difficult; and thirdly, with prolonged use and impact, coupled with bolt aging, bolts are prone to loosening, which can easily lead to flange detachment. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a flange with an anti-detachment structure. This addresses the problem that existing flanges are generally used in pairs and fixed together with multiple bolts. Bolt installation presents many problems, including low installation efficiency, subsequent rusting and inconvenience in disassembly, and the tendency for bolts to loosen easily due to prolonged use, impact, and aging, which can lead to flange detachment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flange with an anti-detachment structure, comprising a flange structure, wherein the surface of the flange structure is covered with a protective structure;

[0005] The flange structure includes a first flange with a groove on its surface, and a connecting groove on one side of the first flange, while a groove plate is fixedly installed on the surface of the connecting groove.

[0006] A through cylinder is fixedly installed inside the first flange, and a limit groove is formed inside the through cylinder.

[0007] By adopting the above technical solution, the through-tube is used to achieve both embedding and fixing, as well as opening on the inner side.

[0008] Preferably, the limiting groove and the connecting groove are rotatably limited to the connecting rod and the connecting plate, respectively, and the connecting rod and the connecting plate are fixedly installed on one side of the second flange, while another groove is provided on the surface of the second flange.

[0009] By adopting the above technical solution, the connecting plate can achieve rotation locking and limiting.

[0010] Preferably, the protective structure includes a spring-loaded cover that wraps around the groove, and the spring-loaded cover wraps around the groove to prevent rainwater from penetrating between the second flange and the first flange.

[0011] By adopting the above technical solution, the spring-loaded cover provides protection.

[0012] Preferably, the limiting grooves are arranged in a circular array, and each limiting groove is arranged in an "L" structure.

[0013] By adopting the above technical solution, the limiting groove is used to achieve connection and limiting.

[0014] Preferably, the connecting rod.

[0015] By adopting the above technical solution, a rotating connection is achieved through the connecting rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the flange with an anti-detachment structure,

[0017] (1) This case solves the problem that existing flanges are generally used in pairs and fixed with multiple bolts by setting up a flange structure. Bolt installation has many problems. First, the installation efficiency is low. After rusting, it is inconvenient to disassemble. Moreover, after long-term use and long-term impact, coupled with the aging of the bolts, the bolts are prone to loosening, which can easily cause the flange to fall off. When the first flange and the second flange need to be installed, the operator manually connects the connecting rod and the connecting plate with the connecting groove and the limiting groove. Then, the operator rotates the second flange so that the connecting rod and the connecting plate are rotated and locked with the connecting groove and the limiting groove, which facilitates the quick connection and installation of the first flange and the second flange. In addition, when there is a gap in the connection after the first flange and the second flange are connected and installed, the corresponding sealing gasket is placed to seal the connection. The flange structure set up avoids the above problems.

[0018] (2) By setting up a protective structure, the problem of rainwater easily penetrating the two flanges after the first flange and the second flange are connected is solved. The first flange and the second flange are wrapped with a spring cover to protect the surface of the first flange and the second flange, thereby preventing rainwater penetration.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a flange with an anti-detachment structure, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the system includes a flange structure 1, which includes a first flange 101 with a groove 102 on its surface. A connecting groove 103 is provided on one side of the first flange 101, and a grooved plate 104 is fixedly installed on the surface of the connecting groove 103. A through cylinder 105 is embedded and fixedly installed inside the first flange 101, and a limiting groove 106 is provided inside the through cylinder 105. The limiting grooves 106 are arranged in a circular array, and each limiting groove 106 is arranged in an "L" structure. When the structure is arranged in a circular array, it not only reflects the axial symmetry of the structure, but also reflects the aesthetics and practicality of the structure. Furthermore, when the structure is arranged in a circular array, it effectively reflects the connection locking and limiting function of the structure. At the same time, when each limiting groove 106 is arranged in an "L" structure, it effectively locks the connecting plate 108 to rotation.

[0027] Furthermore, in the above scheme, the limiting groove 106 and the connecting groove 103 are respectively rotatably limited to the connecting rod 107 and the connecting plate 108. The connecting rod 107 is arranged in a "T" shape. When the overall shape of the above components is arranged in a "T" shape, it not only reflects the practicality of the installation of the above components, but also reflects the locking and limiting function of the rotation of the above components. In addition, when the above components are arranged in a "T" shape, it effectively reflects the matching installation of the above components. The connecting rod 107 and the connecting plate 108 are both fixedly installed on one side of the second flange 109, and another groove 102 is opened on the surface of the second flange 109.

[0028] like Figure 5 As shown, the flange structure 1 is covered with a protective structure 2. The protective structure 2 includes a spring cover 201 that covers the groove 102, and the spring cover 201 covers the groove 102 to prevent rainwater from penetrating between the second flange 109 and the first flange 101.

[0029] In the above scheme, when the spring cover 201 is first inserted through the first flange 101 or the second flange 109, the operator manually aligns the connecting rod 107 and the connecting plate 108 with the connecting groove 103 and the limiting groove 106. Then, the operator rotates the second flange 109 so that the connecting rod 107 and the connecting plate 108 are rotated and locked with the connecting groove 103 and the limiting groove 106, thus facilitating the quick connection and installation of the first flange 101 and the second flange 109. Then, the spring cover 201 is used to wrap and connect with the groove 102 to prevent rainwater penetration of the connected first flange 101 and second flange 109.
