DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0022] As Figures 1 to 3 shown, the present utility model provides a quick-release flange connector, comprising:

[0023] an upper flange 1, a lower flange 2, a gasket 3, an upper clamping ring 4, a lower clamping ring 5, and fasteners. Among them, the upper flange 1 includes an upper end face 11 and an upper flange 12 extending upward along the inner hole of the upper end face 11. The lower flange 2 includes a lower end face 21 and a lower flange 22 extending downward along the inner hole of the lower end face 21. The gasket 3 is disposed between the upper end face 11 of the upper flange 1 and the lower end face 21 of the lower flange 2. The upper clamping ring 4 is sleeved on the upper flange 12 and abuts against the upper end face 11. The lower clamping ring 5 is sleeved on the lower flange 22 and abuts against the lower end face 21. The fasteners lock the upper clamping ring 4 and the lower clamping ring 5 to fix the upper flange 1 and the lower flange 2.

[0024] For the quick-release flange connector of the present utility model, a pair of clamping rings clamp the flange end faces, and the clamping rings are fastened. The fastening force is transmitted to the device to be connected through the flange. When the fastening force is transmitted to the device to be connected through the flange, it is weakened to some extent, and it is not easy to damage the device, which is convenient for connecting devices such as glass and enamel.

[0025] A part of the upper clamping ring 4 extends out of the upper end face 11 to form an upper extension part. A plurality of upper mounting holes 41 are provided in the circumferential direction of the upper extension part. A part of the lower clamping ring 5 extends out of the lower end face 21 to form a lower extension part. A plurality of lower mounting holes 51 are provided on the lower extension part. The plurality of upper mounting holes 41 and the plurality of lower mounting holes 51 are in one-to-one correspondence in the longitudinal direction. The clamping ring extends out of the flange end face by a certain distance, and fasteners are provided on the extension part of the clamping ring, which is convenient for manually screwing the screws.

[0026] For the convenience of material selection, the fasteners include a screw 6 and a nut. The screw 6 passes through the corresponding upper mounting hole 41 and lower mounting hole 51 to lock the upper clamping ring 4 and the lower clamping ring 5.

[0027] The nut is a wing nut 7. By selecting the wing nut 7, the disassembly and assembly operations can be completed solely by hand without the need for any tools throughout the process, which is convenient for assembly.

[0028] The upper clamping ring 4 and the lower clamping ring 5 are both C-shaped. One side of the upper clamping ring 4 has an upper notch 42, and one side of the lower clamping ring 5 has a lower notch 52. Since both the upper clamping ring 4 and the lower clamping ring 5 are C-shaped, when they are sleeved onto the flange flange, the inner diameter of the clamping ring can be adjusted, facilitating the insertion of the clamping ring onto the corresponding flange flange.

[0029] The upper notch 42 and the lower notch 52 are arranged staggeredly, which can ensure the locking stability and prevent the clamping ring from falling off the flange.

[0030] The upper end of the gasket 3 is provided with an upper stop, which abuts against the inner wall of the upper flange 12. The lower end of the gasket 3 is provided with a lower stop, which abuts against the inner wall of the lower flange 22, ensuring the centering of the upper and lower flanges.

[0031] For the quick-release flange connector of the present utility model, the flange end face is clamped by a pair of clamping rings. The clamping rings extend a certain distance from the flange end face. Fasteners are arranged on the extension parts of the clamping rings, facilitating manual screwing of the screws. The disassembly and assembly operations can be completed entirely by hand without the aid of any tools, and it is also impossible to damage containers such as glass and enamel due to excessive force or excessive tightening force.

[0032] All the components selected in this application are common standard components or components known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or obtained through conventional experimental methods.
