Detailed description of the invention
As shown in Figure 1 to Figure 3, the utility model provides a kind of pipe fitting extension fixture, and comprise one first folder valve part 1, rotation section 2, several ring plate 3 and a tightening structure, concrete structure is as follows.
First folder valve part 1 has relative first end 4 and one second end 5, second end 5 forms first conical surface 6 of the circle of a protrusion, first conical surface 6 is toward the direction convergent away from first end 4, first folder valve part 1 also forms the first screw 7 that runs through first end 4 and the second end 5, a first screw 7 wherein opening is positioned at the cone point of first conical surface 6, first conical surface 6 is formed with several stopper slot 8, and each stopper slot 8 extends to cone point at the bottom of the cone of first conical surface 6.
Rotation section 2 comprises one second folder valve part 9 and a forcing piece 10, second folder valve part 9 has one the 3rd relative end 11 and one the 4th end 12,3rd end 11 forms second conical surface 13 of circle, second folder valve part 9 forms the cone point that a wherein opening running through the second screw 14, second screw 14 of the 3rd end 11 and the 4th end 12 is positioned at second conical surface 13.Forcing piece 10 has spiro rod section 15 and a stop section 16, spiro rod section 15 spiral shell is located at the second screw 14 and protrudes from outside the 3rd end 11 of the second folder valve part 9, wear from the second end 5 of the first folder valve part 1 and be screwed together in the first screw 7 again, the external diameter of stop section 16 is greater than the internal diameter of the second screw 14 and is resisted against the 4th end 12 of the second folder valve part 9.
Several ring plate 3 arranges around spiro rod section 15 and is sandwiched between first conical surface 6 and second conical surface 13, each ring plate 3 is respectively equipped with one first inclined-plane 17 and the second inclined-plane 18 towards an opposite end of spiro rod section 15, first inclined-plane 17 and first conical surface 6 are fitted, second inclined-plane 18 and second conical surface 13 are fitted, each ring plate 3 is made to be parallel to the length direction of spiro rod section 15 away from the one side of spiro rod section 15, wherein each ring plate 3 is formed with a fin 19 in the first inclined-plane 17, each fin 19 is embedded at a wherein stopper slot 8 slidably, and each ring plate 3 cannot be rotated relative to the first folder valve part 1.Ring of numbers sheet 3 is formed one cylindric when adjoining one another, the one side of each ring plate 3 spiro rod section 15 is dorsad formed with at least one chase 20, and chase 20 each other position is corresponding and common linking number ring plate 3 extends.
Tightening structure comprises the flexible beam ring 21 of at least one tool, and beam ring 21 is sheathed on outside ring plate 3 and is embedded in chase 20, draws close so as to ring plate 3 being tightened each other, gets loose or angle inequality to avoid ring plate 3.
In addition, a joint face 22 is had between first inclined-plane 17 of each ring plate 3 and the second inclined-plane 18, the one side of joint face 22 and ring plate 3 spiro rod section 15 is dorsad parallel, fin 19 extends on the first inclined-plane 17 towards the second direction, inclined-plane 18, be connected with a junction 23 between joint face 22 with fin 19, connecting portion 23 and joint face 22 for same plane and not with the top surface being parallel of fin 19.
In addition; the length direction of spiro rod section 15 defines a longitudinal axis; first conical surface 6 and second conical surface 13 along this axle length and be greater than the length of each ring plate 3 along the longitudinal axis; therefore; when the first folder valve part 1 and second press from both sides valve part 9 close to each other and support time, these ring plates 3 just cannot move further outwardly, and being pressed from both sides valve part 1 and second to avoid ring plate 3 by first presss from both sides excessive extrapolation of valve part 9 and tilt to conjugate; guarantee that ring plate 3 can remain parallel and stable, body can be expanded fifty-fifty.
During use, first ring plate 3 is placed in a pipe fitting for expansion place, when the distance between the first folder valve part 1 and rotation section being reduced when rotating rotation section, these ring plates 3 to be pushed towards the direction away from spiro rod section 15 by first conical surface and second conical surface and away from each other, namely ring plate 3 moves radially outward, and then push against inboard wall of tube body and it is pushed outward, reach the object of tubular member internal diameter.After expansion completes, only need to rotate backward rotation section, make the first folder valve part 1 relatively away from the second valve part 21, ring plate 3 just can be close to each other because of the elastic force of beam ring 21, and total external diameter of ring plate 3 just reduces, and now the utility model can be removed in pipe fitting.
Fin of the present utility model force in respectively each ring plate mid portion but not between ring plate, the effect of ring plate being located is better, can not cause the distortion between ring plate, and ring plate is stressed also can be comparatively average overall to ring plate respectively, durability and intensity are all good, and practicality is better.
