Summary of the invention
Goal of the invention of the present utility model provides a kind of instant sealing device of, compact, reliable in action simple for single circular fitting structure in order to overcome prior art above shortcomings.
The technical solution of the utility model is: compressor arm is set with successively the first clamping piece, elastic seal ring, coordinates elastic seal ring to be pressed in internal wall of pipe orifice with the second clamping piece of sealing orifice with the first clamping piece; The eccentric wheel moving to extrude elastic seal ring along compressor arm to the first clamping piece for promoting the second clamping piece is connected to compressor arm.
Described first clamping piece, one end that the second clamping piece is relative are respectively equipped with the chamfering being convenient to elastic seal ring to extrude to internal wall of pipe orifice.
Described eccentric wheel through rivet interlacement in compressor arm second clamping piece institute at one end.
Described first clamping piece is fixed on compressor arm.
Described first clamping piece activity is loaded on compressor arm; On described compressor arm, the first clamping piece is at one end provided with the back-up ring for spacing first clamping piece.
Described eccentric wheel is connected with handle.
Described handle is connected to eccentric wheel circumferentially distance eccentric wheel eccentric opening farthest.
Described first clamping piece, the second clamping piece are class frustum cone structure, and class round platform upper base diameter is D
4, diameter of going to the bottom is D
3; Angle between the bus of class round platform and axle is a; Eccentric opening is L1 to eccentric wheel circumference beeline, and during rotation eccentric handle, eccentric opening is L2 to compressor arm distance; Described elastic seal ring inner ring diameter is D

1)/2; Twisting eccentric handle, press seal rubber ring deformation quantity is: δ
2=(L2-L1)/2 × tan(a); δ
2be greater than δ
1, sealing can be realized.
Described compressor arm passes the center of the first clamping piece and the second clamping piece, and compressor arm and the first clamping piece can be welded as a whole, and prevent central hole from leaking.
During use, handle is turned to and is in relaxation state with during compressor arm level, all can realize inflatable elastomeric seal ring gradually when rotating to both sides from this state and block water space and play seal action.
Compared with prior art, the utility model structure is simple, compact, reliable in action, can seal pipe fast and effectively, enhance productivity; Avoid that comprehensive structure for pressure test volume is large, complicated operation simultaneously, reduce the manufacture difficulty of frock, cost-saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of eccentric handle.
In figure: 1 handle 2 rivet 3 second clamping piece 4 compressor arm 5 elastic seal ring
