Description

Technical Field

[0001] This application relates to the technical field of flanges, and particularly to a flange structure that is easy to disassemble. Background Art

[0002] As a common means of connecting pipelines and equipment, flange structures are widely used in industrial fields such as chemical industry, petroleum, natural gas, water conservancy, air conditioning, and heating. Although traditional flange structures have a certain degree of connection stability, they often face problems of complex operation, time-consuming, and laborious during disassembly and maintenance. Therefore, developing a flange structure that is easy to disassemble and improving the disassembly efficiency and convenience has become a technical problem that urgently needs to be solved in the current industrial field. Existing detachable flange structures, because they meet the requirements of disassembly, their connections are not firm. Therefore, there is a need in the market for a flange structure that meets the disassembly requirements while ensuring a firm connection. Summary of the Utility Model

[0003] The purpose of the embodiments of this application is to provide a flange structure that is easy to disassemble, so as to solve the technical problems of insecure connection and inconvenient disassembly existing in the prior art.

[0004] To achieve the above purpose, the technical solution adopted in this application is: to provide a flange structure that is easy to disassemble, including a first flange and a second flange; the first flange is fixedly arranged, and the second flange is detachably arranged on the first flange; the second flange has a middle hole; the second flange further includes a connecting pipe coaxially arranged with the middle hole; the connecting pipe is threadedly connected to the first flange; a fixing component is arranged on the connecting pipe; the fixing component is detachably connected to the first flange.

[0005] Through the above technical solution, the first flange and the second flange can be separated relatively. The setting of the two flanges is prior art and can realize the connection of both ends of two objects. The connecting pipe is used to connect the two flanges and facilitate communication. However, the form of threaded connection between the connecting pipe and the first flange is not firm and stable.

[0007] Through the above technical solution, the connecting rods can achieve support and connection strengthening. Because the connecting pipe is threadedly connected to the first flange and needs to be rotated during threaded connection, the lower ends of the connecting rods cannot be fixedly connected to the first flange. Therefore, the inclined surfaces are arranged to abut against each other.

[0008] Optionally, a first arc-shaped hole opposite to the inclined surface is provided on the upper side of the first flange; a second arc-shaped hole is provided in the first arc-shaped hole; the width of the second arc-shaped hole is greater than the width of the first arc-shaped hole; the number of the first arc-shaped holes and the second arc-shaped holes is adapted to the number of connecting rods; the first arc-shaped hole and the second arc-shaped hole are arranged in an arc shape, and the angle between one end to the other end and the axis of the middle hole is 15 to 30 degrees.

[0009] Through the above-mentioned technical solution, by setting the inclined surfaces relative to each other, a certain supporting and stabilizing effect can be achieved, and by setting the first arc hole and the second arc hole, the connecting rod can be fixed after rotation, further improving the supporting and stabilizing effect, ensuring the connection strength, and the setting of the angle can more conveniently adapt to the connecting rod after threaded connection.

[0010] Optionally, a countersunk hole is provided at the lower end of the connecting rod; the countersunk hole is adapted to the screw; a T-shaped nut is provided in the second arc-shaped hole; and the screw is threadedly connected to the T-shaped nut after passing through the countersunk hole.

[0011] Through the above technical solution, the T-shaped nut is located in the second arc-shaped hole and then limited by the first arc-shaped hole. After connection, it will not separate from the first arc-shaped hole, thereby achieving fixation of the connecting rod.

[0012] Optionally, a plurality of first mounting holes are provided on the first flange; the first mounting holes are equally distributed outside the middle hole; a threaded hole coaxial with the middle hole is provided in the middle of the first flange; an external thread is provided at the lower end of the connecting pipe; and the lower end of the connecting pipe is threadedly connected to the threaded hole.

[0014] Optionally, the lower end of the connecting pipe is in communication with the middle hole; a plurality of second mounting holes are provided on the second flange; and the second mounting holes are equally distributed outside the middle hole.

[0015] Optionally, internal threads are provided in the first mounting hole and the second mounting hole.

[0016] Through the above technical solution, the first mounting hole and the second mounting hole are used to achieve installation. It is a prior art that threaded holes are opened on an external object to correspond to the first mounting hole and the second mounting hole, and the installation effect is achieved by using screws.

[0026] Such as Figures 1 to 2As shown in the figure, the purpose of the embodiment of the present application is to provide a flange structure that is easy to disassemble, so as to solve the technical problems of insecure connection and inconvenient disassembly existing in the prior art. To achieve the above purpose, the technical solution adopted by the present application is: to provide a flange structure that is easy to disassemble, including a first flange 1 and a second flange 2; the first flange 1 is fixedly arranged, and the second flange 2 is detachably arranged on the first flange 1; the second flange 2 has a middle hole 3; the second flange 2 further includes a connecting pipe 4 coaxially arranged with the middle hole 3; the connecting pipe 4 is threadedly connected to the first flange 1; a fixing component is arranged on the connecting pipe 4; the fixing component is detachably connected to the first flange 1.

[0033] Through the above technical solution, the T-shaped nut is located in the second arc-shaped hole 7 and then limited by the first arc-shaped hole 6, and will not break away from the first arc-shaped hole 6 after connection, realizing the fixation of the connecting rod 5.
