Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, the present invention is described further:
A kind of Pneumatic pipeline connector as shown in Figure 1 and 2, including outer ring 1, centre circle 2, movable block 4, sliding shoe 6 and the flexible glue inner ring 3 being loaded on external pipe 100 for sealing shroud, outer ring 1, centre circle 2 and flexible glue inner ring 3 three are coaxial and internal diameter is sequentially reduced, a chute 5 is passed through affixed between outer ring 1 and centre circle 2, movable block 4 is built in chute 5 and is slidably matched with the sealing of this chute 5, the medial extremity of movable block 4 is connected with the inwall elasticity with outer ring 1, and flexible glue inner ring 3 has the groove 301 of the outboard end insertion for movable block 4;The cell wall of chute 5 has the first inlet channel 501, the first Non-return air valve 502 being passed through in chute 5 for gas unidirectional it is provided with in this first inlet channel 501, the medial extremity of the first inlet channel 501 connects with chute 5 and between the medial extremity and the inwall of outer ring 1 of movable block 4, block the first inlet channel 501 with the movement by movable block 4 or open the first inlet channel 501, the outboard end of the first inlet channel 501 is communicated with an air chamber 7, and air chamber 7 locular wall away from this first inlet channel 501 is set to elastic film 71;Having inside groove 11 along its circumference on outer ring 1, sliding shoe 6 back-off is slidably matched in this inside groove 11 and with this inside groove 11 circumference around outer ring 1, and this sliding shoe 6 has the end 61 compressed with elastic film 71;Outer ring 1 is additionally provided with the second inlet channel 101 and exhaust passage 102, second inlet channel 101 connects with air chamber 7, the second Non-return air valve 103 being passed through in air chamber 7 for gas unidirectional it is provided with in this second inlet channel 101, exhaust passage 102 connects with chute 5, and this exhaust passage 102 seals and is fitted with sealing-plug 104.
nullManually rotate outer ring 1,The outboard end that just can make movable block 4 intermittently inserts groove 301,After inserting groove 301,The medial extremity of movable block 4 will closure the first inlet channel 501,So that movable block 4 is pressed by chute 5 internal gas pressure,And after the outboard end of movable block 4 departs from groove 301,By back and forth stirring sliding shoe 6,End 61 extruding is made to clash into elastic film 71,To so that air chamber 7 is constantly from the second inlet channel 101 one-way air inlet,When after the gas excess entered,When the outboard end of movable block 4 inserts again in groove 301,Gas in air chamber 7 will be forced into chute 5,To strengthen the pressure to movable block 4,This action repeatedly,,Until after convenient pressure,After the outboard end of movable block 4 inserts groove 301 for the last time,To form the clamping force to flexible glue inner ring 3,Thus effectively seal against clamping pipe 100,Possess good air-tightness and watertightness,Flexible glue inner ring 3 then can form good effective shock resistance to the connection flexibility of pipeline 100;Meanwhile, by the most persistently rotating outer ring 1 or reciprocating rotation outer ring 1 and back and forth stirring sliding shoe 6 and just constantly can pressurize to movable block 4 and realize the connection of two pipelines 100 and seal installation;By taking out sealing-plug 104, it is possible to chute 5 Rapid degassing, movable block 4 is able to release, forms quickly dismounting, and mounting or dismounting the most of the present invention are convenient, applied widely.
Wherein, the first sealing shroud of flexible glue inner ring 3 is loaded on the mouth of pipe of two pipelines 100, it is set with outer ring 1, centre circle 2 again, outer ring 1 is for hand-held rotation, to drive centre circle 2 synchronous axial system when this outer ring 1 rotates, movable block 4 is by after the ever-increasing air pressure of its medial extremity in chute 5, and movable block 4 will slide in chute 5, its outboard end will support in groove 301, give flexible glue inner ring 3 clamping force.Especially, by end 61, the intermittence of elastic film 71 is compressed, make elastic film 71 cave inward deformation, the air of compressible air chamber 7, forms air pressure and is clamp-oned by air in chute 5, after elastic film 71 resets, under ambient pressure effect, the unidirectional air chamber 7 that is filled with is supplemented air by outside air.
For end 61 is formed spacing, prevent from destroying elastic film 71, described end 61 is in step-like, there is the First terrace 611 in inside groove 11 and the second step face 612 between outer ring 1 and centre circle 2, second step face 612 protrudes from First terrace 611, the sidewall of inside groove 11 is positioned at the outside of elastic film 71, so that after second step face 612 compresses elastic film 71 prior to First terrace 611 contact, First terrace 611 is just realized spacing by the sidewall of inside groove 11.
For prevent the outboard end of movable block 4 in groove 301 stuck, the bottom land plane of groove 301 is inclined-plane, and accordingly, the outboard end of described movable block 4 is set to oblique top, then by the most persistently rotating outer ring 1, so that it may complete the inflating pressure to chute 5.
For making movable block 4 that the pressure of flexible glue inner ring 3 more to be equalized, further to promote air-tightness and watertightness, movable block 4, sliding shoe 6 at least two, with the axis axial symmetry distribution of flexible glue inner ring 3, described chute 5, inside groove 11, groove the 301, first inlet channel 501, air chamber 7, elastic film the 71, second inlet channel the 101, first Non-return air valve the 502, second Non-return air valve 103, exhaust passage 102 and the sealing-plug 104 that corresponding configuration quantity is identical.Accordingly, for preventing movable block 4 stuck, inclined-plane tilts the most in the same direction.
As preferred embodiment, the medial extremity of movable block 4 is connected with the inwall elasticity of outer ring 1 by a spring 8;Spring 8 is used to provide reseting elasticity.Certainly, spring 8 may be used without the flexible member replacements such as elastic rubber fitting.
As preferred embodiment, for the benefit of movable block 4 realizes more efficiently plug for seal to the first inlet channel 501 in sliding process, simultaneously for preventing gas leakage, described first inlet channel 501, in horn-like, has the osculum 5011 towards chute 5 side and the big mouth 5012 towards air chamber 7 side.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various corresponding changes and deformation, and within all these changes and deformation all should belong to the protection domain of the claims in the present invention.
