Its principle is: during assembling condition, and described oval seal ring can be set in elliptic flexible waveguide outer wall, and inner side end and the second hole section of described oval seal ring and flange clip coordinate.Overcoat flange plate, flange clip and elliptic flexible waveguide can be locked by fastening described screw and reach hermetic seal effect.Flange clip is formed by two split block assembly, this structure, and it is very convenient to assemble and dismantle.The hole wall in the elliptical center hole set by flange clip is provided with helical corrugation, helical corrugation with match with the helical corrugation shape of adjacent ellipses flexible waveguide, ensured the overall steadiness be connected elliptic flexible waveguide linkage structure of flange clip and flange further.
A kind of improvement also comprises the second groove being located at described flange clip cylindrical sidewall and the collar matched.The collar that can snap in the second groove has ensured the steadiness of split block assembly.
Another kind of improvement is that described collar is rubber ring.Rubber ring has elasticity, is installed in the second groove of flange clip sidewall, makes two split block secure fit of flange clip.Rubber ring can be silicon rubber loop.
A kind of improvement is also had to be that described collar is elastic metallic landolsring.Elastic metallic landolsring is the semi-loop being greater than semicircle jaggy, can snap in the second groove by breach elastic metallic landolsring, can reach the effect of two the split block secure fit making flange clip equally.
The utility model tool has the following advantages:
1, flange clip is formed by two split block assembly, and this split-type structural is extremely convenient to installation and removal.2, by the flange clip of two split block assembly, the hole wall in its elliptical center hole forms complete ellipse spiral ripple, can with the fitting tightly of adjacent ellipses flexible waveguide, ensured integrally-built superpower steadiness.3, telecommunication parameter can accurate recovery after repeated disassembled and assembled, reproducible.4, collar has elasticity, and can be rubber ring or elastic metallic landolsring, collar be installed in the second groove of flange clip sidewall, makes the flange clip of two split block assembly more firm.
