And the sealing cover of hollow hemisphere shape is by the change in displacement of himself, compression exclusion can be carried out to the air in pipeline, make the bigger air pressure with sealing cover inside of the air pressure in the sealing cover external world, so make sealing cover more stable be fixed on inner-walls of duct; And radiation is embedded with multiple arc-like sheet on the sealing cover outer wall being pointed to its outer eaves by the bottom of sealing cover, the effect of stiffening rib can be played to sealing cover body, to ensure the stability of the sealing cover body when push rod drives sealing cover to move, solve blocking device poor practicability in the past, awkward problem.
Further, the curved inner wall of described elastic metallic block has multiple retraction slot, and multiple described retraction slot is parallel to each other.Described elastic metallic block is curved shape, mainly the deformation of expansion section provided support in shutoff process and strengthen the squeezing effect to inner-walls of duct, but can metal fatigue be there is at long-term using process Elastic slug and cause it to damage, the utility model offers multiple retraction slot side by side at the curved section of elastic metallic block, and when expansion section Bending Deformation, by the gap adjustment between retraction slot and then the metal fatigue reducing elastic metallic block self, extend the working life of elastic metallic block.
Further, the cross section of described retraction slot is circular or oval.As preferably, the cross section of retraction slot is set to circle or ellipse, relative to existing rectangle groove or dovetail groove, eliminate the drift angle of rectangular or rhombus, there is no obvious summit, decrease the possibility of tearing retraction slot from summit, thus substantially increase its working life, the elastic metallic block avoiding inappropriate external force in using process to cause damages.
The utility model compared with prior art, has following advantage and beneficial effect:
1, the sealing cover of hollow hemisphere shape of the present utility model is by himself change in displacement, compression exclusion can be carried out to the air in pipeline, make the bigger air pressure with sealing cover inside of the air pressure in the sealing cover external world, so make sealing cover more stable be fixed on inner-walls of duct; And radiation is embedded with multiple arc-like sheet on the sealing cover outer wall being pointed to its outer eaves by the bottom of sealing cover, the effect of stiffening rib can be played to sealing cover body, to ensure the stability of the sealing cover body when push rod drives sealing cover to move, solve blocking device poor practicability in the past, awkward problem;
2, the utility model offers multiple retraction slot side by side at the curved section of elastic metallic block, and when expansion section Bending Deformation, by the gap adjustment between retraction slot and then the metal fatigue reducing elastic metallic block self, extend the working life of elastic metallic block;
3, the cross section of retraction slot is set to circle or ellipse by the utility model, relative to existing rectangle groove or dovetail groove, eliminate the drift angle of rectangular or rhombus, there is no obvious summit, decrease the possibility of tearing retraction slot from summit, thus substantially increasing its working life, the elastic metallic block avoiding inappropriate external force in using process to cause damages.
