Description

Technical Field

[0001] The utility model relates to the technical field of flange production, in particular to a flange component. Background Art

[0002] Flanges are commonly used connection structures in industrial production lines. In order to prevent static sparks from being generated due to static electricity accumulation during the production process, the flanges need to be grounded when the number of connecting bolts of each pair of flanges is less than five. The existing flange grounding method is to connect the copper plate to the two flanges through bolts, but the bolts may rust after long-term use, which reduces the conductivity and affects the grounding of the flanges. In addition, the existing connection method is cumbersome in operation. Utility Model Content

[0003] The technical problem to be solved by the utility model is: a flange assembly, which ensures the conductivity between adjacent flange sheets and reduces the difficulty of bridging.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A flange assembly comprises a first flange, a second flange, a conductive member and a fastener;

[0006] The first flange is arranged opposite to the second flange, one end of the conductive member is fixedly connected to the first flange, and the other end of the conductive member is detachably connected to the second flange via the fastener.

[0007] Furthermore, the conductive member is welded to the first flange.

[0008] Furthermore, two ends of the conductive member in the length direction are flush with the end surface of the first flange and the end surface of the second flange respectively.

[0009] Furthermore, a first notch is formed on the circumferential outer wall of the first flange, and a second notch is formed on the circumferential outer wall of the second flange directly opposite to the first notch;

[0010] Two ends of the conductive member are respectively embedded in the first notch and the second notch.

[0011] Furthermore, two ends of the conductive member match the first notch and the second notch respectively.

[0012] Furthermore, a threaded hole is formed on the circumferential outer wall of the second flange, and the threaded hole is located in the second notch.

[0013] Furthermore, the length of the conductive member is equal to the total thickness of the first flange and the second flange.

[0014] Furthermore, the conductive member and the first flange are integrally injection molded.

[0015] The beneficial effect of the utility model is that by fixedly connecting one end of the conductive member to the first flange instead of the bolt connection, the conductive member always maintains a connection relationship with the first flange, thereby improving the connection tightness between the conductive member and the first flange, facilitating the connection of the other end of the conductive member to the second flange, and reducing the difficulty of operation during bridging.

[0022] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0023] Please refer to Figure 1 as well as Figure 2 A flange assembly includes a first flange 1, a second flange 2, a conductive member 3 and a fastener 4; the first flange 1 is arranged opposite to the second flange 2, one end of the conductive member 3 is fixedly connected to the first flange 1, and the other end of the conductive member 3 is detachably connected to the second flange 2 through the fastener 4. Preferably, the conductive member 3 is made of copper.

[0024] It can be understood that by fixedly connecting one end of the conductive part 3 to the first flange 1 instead of the bolt connection, the conductive part 3 is always connected to the first flange 1, thereby improving the connection tightness between the conductive part 3 and the first flange 1, facilitating the connection of the other end of the conductive part 3 to the second flange 2, and reducing the difficulty of operation during bridging.

[0025] In some embodiments, the conductive member 3 is welded or integrally injection molded with the first flange 1 , so that one end of the conductive member 3 is fixedly connected to the first flange 1 , thereby improving the connection strength between the conductive member 3 and the first flange 1 .

[0026] In some embodiments, both ends of the conductive member 3 in the length direction are flush with the end faces of the first flange 1 and the second flange 2, respectively, to prevent the conductive member 3 from contacting other structures and to prevent the conductive member 3 from interfering with the installation of the flange.

[0027] In some embodiments, a first notch 11 is provided on the circumferential outer wall of the first flange 1, and a second notch 21 is provided on the circumferential outer wall of the second flange 2, which is directly opposite to the first notch 11; the two ends of the conductive member 3 are respectively embedded in the first notch 11 and the second notch 21. Preferably, the two ends of the conductive member 3 are respectively matched with the first notch 11 and the second notch 21. The provision of the first notch 11 and the second notch 21 facilitates the positioning of the conductive member 3 when it is connected to the flange. At the same time, since the conductive member 3 is connected to the second flange 2 through the fastener 4, the provision of the second notch 21 can expand the contact area between the conductive member 3 and the second flange 2. Even if the fastener 4 is used for a long time and rusts, the conductive member 3 can still be effectively electrically connected to the inner wall of the second notch 21 and the body of the second flange 2.

[0028] In some embodiments, a threaded hole 22 is formed on the circumferential outer wall of the second flange 2, and the threaded hole 22 is located in the second notch 21. Specifically, the fastener 4 is a bolt.

[0029] In some embodiments, the length of the conductive member 3 is equal to the total thickness of the first flange 1 and the second flange 2 , ensuring that the first flange 1 and the second flange 2 can fit tightly and preventing the conductive member 3 from interfering with the connection between the first flange 1 and the second flange 2 .

[0031] A flange assembly includes a first flange 1, a second flange 2, a conductive member 3 and a fastener 4; the first flange 1 and the second flange 2 are arranged opposite to each other and coaxially, one end of the conductive member 3 is welded to the first flange 1, and the other end of the conductive member 3 is detachably connected to the second flange 2 through the fastener 4. Preferably, the conductive member 3 is made of copper. The first flange 1 and the second flange 2 are connected by four fixing bolts 5.

[0032] In this embodiment, both ends of the conductive member 3 in the length direction are flush with the end faces of the first flange 1 and the second flange 2 respectively. Furthermore, the length of the conductive member 3 is equal to the total thickness of the first flange 1 and the second flange 2.

[0033] In this embodiment, a first notch 11 is formed on the circumferential outer wall of the first flange 1, and a second notch 21 opposite to the first notch 11 is formed on the circumferential outer wall of the second flange 2; two ends of the conductive member 3 are respectively embedded in the first notch 11 and the second notch 21; a threaded hole 22 is formed on the circumferential outer wall of the second flange 2, and the threaded hole 22 is located in the second notch 21; two ends of the conductive member 3 are respectively matched with the first notch 11 and the second notch 21.

[0034] The working principle of the utility model is:

[0035] After the first flange 1 and the second flange 2 are connected by the fixing bolts 5 , the other end of the conductive member 3 is embedded in the second notch 21 , and the conductive member 3 is connected to the second flange 2 by the fastener 4 .
