A detachable flange comprises: two first flanges 10, a disassembly assembly 20 is provided inside the first flange 10, and positioning assemblies 30 are provided inside the first flange 10 and on the left and right sides of the disassembly assembly 20;

[0024] The disassembly assembly 20 includes a second flange 21 disposed inside the first flange 10. The second flange 21 is provided with six connecting grooves 22 on its sides. A clamping groove 23 is provided on both the left and right sides of the second flange 21. A connecting pipe 24 is provided through the center of the inner side of the second flange 21 and is threadedly connected to the connecting pipe.

[0025] When the staff is using the device, they thread the connecting pipe 24 onto the inner side of the second flange 21 and pass it through the bottom of the first flange 10, so that the second flange 21 is installed on the inner side of the mounting groove 25, and is engaged with the surface of the connecting block 26 through the connecting groove 22, thereby increasing the firmness of the connection between the first flange 10 and the second flange 21, and completing the installation. In this way, the connecting pipe 24 can be replaced according to the size of the specification, which is convenient for the staff to use.

[0026] The positioning assembly 30 includes a threaded rod 31 rotatably mounted on the inner side of the first flange 10 and located on the left and right sides of the second flange 21. A positioning block 32 is sleeved on the surface of the threaded rod 31 and threadedly connected thereto. A movable groove 33 is provided on the inner side of the first flange 10 for the positioning block 32 to slide left and right. A positioning sleeve 34 is fixedly mounted on the side of the positioning block 32 near the first flange 10 and on the outer edge of the threaded rod 31.

[0027] By rotating the adjusting block 35 through the tool, the adjusting block 35 drives the threaded rod 31 to rotate, and the threaded rod 31 drives the positioning block 32 to slide toward the center on the inner side of the movable groove 33. The positioning block 32 drives the positioning sleeve 34 to pass through the connecting hole and is inserted into the inner side of the positioning hole 27. At the same time, the embedded clamping block 36 provided at the bottom of the positioning block 32 passes through the inner side of the notch 28 and extends to the outside of the first flange 10, so that it is engaged with the inner side of the clamping groove 23, thereby limiting the second flange 21 and the connecting pipe 24, increasing the limiting effect of the device, and improving the practicality of the device.

[0028] A mounting groove 25 adapted to the second flange 21 is formed on the inner side of the first flange 10 . A connecting block 26 adapted to the connecting groove 22 is fixedly mounted on the inner side of the mounting groove 25 . The multiple connecting blocks 26 are integrally provided with the first flange 10 .

[0029] Positioning holes 27 adapted to the positioning sleeve 34 are provided on both the left and right sides of the connecting pipe 24 , and a communicating hole for the positioning sleeve 34 to pass through is provided on the inner side of the first flange 10 .

[0030] A notch 28 for the positioning block 32 to pass through is provided on the inner side of the first flange 10 and on one side of the clamping groove 23 . An embedded clamping block 36 adapted to the clamping groove 23 is provided on the surface of the positioning block 32 near the bottom.

[0031] An adjusting block 35 for driving the threaded rod 31 to rotate is rotatably provided on the inner side of the first flange 10 , and a groove for the adjusting block 35 to rotate is provided on the surface of the first flange 10 .

[0032] A plurality of mounting holes are provided on the inner sides of the two first flanges 10 . A fixing bolt 40 is threadedly connected to the inner sides of the two mounting holes on the same side. A fastening ring 50 is threadedly provided on the outer edge of the fixing bolt 40 near the bottom end.

[0033] The working principle of the detachable flange provided by the utility model is as follows:

[0034] Step 1: When the device is in use, the connecting pipe 24 is threadedly connected to the inner side of the second flange 21 and passed through the bottom of the first flange 10, so that the second flange 21 is installed inside the mounting groove 25, and is engaged with the surface of the connecting block 26 through the connecting groove 22, thereby increasing the firmness of the connection between the first flange 10 and the second flange 21. The installation is completed, and the connecting pipe 24 can be replaced according to the size of the specification, which is convenient for the staff to use;

[0035] Step 2: Use the tool to rotate the adjusting block 35, and the adjusting block 35 drives the threaded rod 31 to rotate. The threaded rod 31 drives the positioning block 32 to slide toward the center on the inner side of the movable groove 33. The positioning block 32 drives the positioning sleeve 34 to pass through the connecting hole and is inserted into the inner side of the positioning hole 27. At the same time, the embedded clamping block 36 provided at the bottom of the positioning block 32 passes through the inner side of the notch 28 and extends to the outside of the first flange 10, so that it is engaged with the inner side of the clamping groove 23, thereby limiting the second flange 21 and the connecting pipe 24, increasing the limiting effect of the device and improving the practicality of the device.

[0036] Compared with the related art, the detachable flange provided by the present invention has the following beneficial effects:

[0037] By cooperating with each other in the arrangement of the various components of the device, the connecting pipe 24 is threadedly connected to the inner side of the second flange 21 and passes through the bottom of the first flange 10, so that the second flange 21 is installed on the inner side of the mounting groove 25, and is engaged with the surface of the connecting block 26 through the connecting groove 22, thereby increasing the firmness of the connection between the first flange 10 and the second flange 21, and completing the installation. In this way, the connecting pipe 24 can be replaced according to the specifications and size, which is convenient for the staff to use. In conjunction with the function of the positioning component 30, the second flange 21 and the connecting pipe 24 are limited, thereby increasing the limiting effect of the device and improving the practicality of the device.
