Detailed description of the invention

In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.

As shown in Figure 1, a kind of yarn ellipsoid tensioner, comprise with the interconnected upper cover 2 of internal and external threads and lower cover 4, upper cover 2 and lower cover 4 are cylindrical shape, the open-top screw thread of upper cover 2 lower ends and lower cover 4 upper ends is connected to each other, upper cover 2 upper ends and lower cover 4 lower ends are respectively equipped with little opening, the spool 10 of pop-up 6 is upward through the upper cover 2 little openings in upper end, the spool 10 of subiculum 8 is down through the lower cover 4 little openings in lower end, spool 10 is tubular structure, yarn 20 can be smoothly by its hollow entering in sacculus 14, pop-up 6 and subiculum 8 opposite ends are equipped with the hemispherical concave surface of relative orientation, hemispherical concave edge is fixedly connected with two free ends of sacculus 14, sacculus 14 vertical directions are provided with 2-4 blister cavities 16, blister cavities 16 inner wall shape are spherical, and vertically arrange, each blister cavities 16 inside are equipped with an outside dimension and are slightly less than the tension force ellipsoid 18 of blister cavities 16 internal diameters, between adjacent blister cavities 16, be communicated with by yarn road, so just form yarn path of the present utility model: from subiculum 8 spools 10, to gap between the inner blister cavities 16 of sacculus 14 and tension force ellipsoid 18, finish to pop-up 6 spools 10 again, form the yarn path of an inner wall smooth.

Be provided with the spring on the spool 10 that is located in pop-up 6 in upper cover 2 inside, be provided with the spring on the spool 10 that is located in subiculum 8 in lower cover 4 inside simultaneously, two springs are all spacing in tensioner inside by the hemisphere face of the hemisphere face of pop-up 6 and upper cover 2 or subiculum 8 and lower cover 4, spring can be easy to pop-up 6, subiculum 8 and the soft contact of sacculus 14 three between 2 lower covers 4 of upper cover, reduce the hard collision of sacculus 14 and tensioner upper cover 2 and lower cover 4, while making yarn 20 by tensioner, be not easy to be subject to external force impact.

As shown in Figure 2, in use, yarn 20 enters from spool 10 upper ends of pop-up 6 the utility model, along the hollow hemisphere face that enters pop-up 6 of spool 10, then enter successively in interior blister cavities 16 of sacculus 14, at the hemisphere face that enters subiculum 8, the spool 10 that enters again subiculum 8, finally leaves tensioner.When yarn moves in tensioner, when yarn 20 moves along yarn path from top to bottom in tensioner, tension force ellipsoid 18 is because the existence of gravity can be pressed in the bottom of its place blister cavities 16, and then yarn 20 is formed to certain grasping force, multiple tension force ellipsoids 18 several grasping forces of stack that are arranged above and below form an overall stability, lasting yarn 20 tension force controls, multiple tension force ellipsoids 18 can prevent from only having some tension force ellipsoids 18 in tension force ellipsoid 18 situations due to the grasping force extinction tests of beating and forming.

Be enlightenment according to desirable embodiment of the present utility model above, by above-mentioned description, related personnel can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine technical scope according to claim scope.
