In order to solve the technical problems, the technical scheme provided by the utility model is as follows: the utility model provides a universal cover that induced drafts convenient to dismouting, includes universal rotating frame and cover body, is located connecting pipe and the fixed pipe that is located cover body one end of universal rotating frame one end, be equipped with in the fixed pipe with connecting pipe complex air flue two, be equipped with on the inner wall of air flue two in the fixed pipe and be annular evenly distributed's flange, be equipped with air flue one in the connecting pipe, be equipped with in the connecting pipe not less than one and be annular evenly distributed and flange complex recess, be equipped with the fixed block of relative arrangement on the universal rotating frame in the below of connecting pipe, both sides all be equipped with the screw hole in the fixed block, be equipped with the relative arrangement respectively with both sides screw hole complex screw hole through-hole in the fixed pipe.
Compared with the prior art, the utility model has the advantages that: when changing the cover body, in inserting each recess that corresponds with the boss in the air duct II, reuse bolted connection screw thread through-hole and screw hole, can improve the gas tightness of air duct I and air duct II like this, and boss cooperation recess can play the guide effect, can also improve the stability of fixed pipe installation on the connecting pipe, effort is on the fixed pipe of old cover body when dismantling the bolt, can avoid external force to make the fixed block produce deformation, can prevent like this that the unstable gas that leaks that leads to of being connected between cover body and the universal rotating frame behind the new cover body.
As an improvement, the threaded holes are connected with the threaded through holes through bolts.
As improvement, the universal rotating frame is provided with anti-skid patterns, so that the friction force between hands and the universal rotating frame can be increased, and the angle of the cover body can be conveniently adjusted by grasping the universal rotating frame.
As an improvement, both sides of the fixed pipe are adhered with rubber gaskets matched with the threaded through holes, so that the stability of the bolt tightening can be improved.
As an improvement, sealing strips are adhered to the inner wall of the groove, so that the tightness of the convex plate when the convex plate is inserted into the groove can be improved.
