Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of tightenable household tieback, including Device noumenon 1, described device ontology 1 is by being arranged in the bearing bar 8 of 1 bottom of device noumenon and being arranged among the bearing bar 8 The shaft 2 of position is constituted, and the inside of the shaft 2 is equipped with bull stick 15, and the bull stick 15, which runs through, to be arranged in shaft 2, and described The end of bull stick 15, which is respectively embedded into, to be arranged in bearing bar 8, and the top of the shaft 2 is equipped with spring 9 and pull rod 10, and the drawing Bar 10 is embedding to be set on spring 9, and is fixedly connected with spring 9, and the top of the bearing bar 8 is respectively equipped with the first contact pin 3, Two contact pins 4, third contact pin 5 and the 4th contact pin 6, and first contact pin 3, the second contact pin 4, third contact pin 5 and the 4th contact pin 6 it Between be uniformly distributed in " one " word, and closely welded with bearing bar 8, side and the spring of second contact pin 4 and third contact pin 5 9 symmetric side is equipped with weldering patch 12, and the weldering patch 12 is welded with the second contact pin 4, third contact pin 5 and spring 9 respectively.

Further, the top of first contact pin 3, the second contact pin 4, third contact pin 5 and the 4th contact pin 6 is equipped with stainless The round end 7 of steel material, and the round end 7 is welded with the first contact pin 3, the second contact pin 4, third contact pin 5 and the 4th contact pin 6 respectively, The round end 7 can prevent from causing to scratch to curtain in contact pin insertion curtain.

Further, the top of the pull rod 10 is equipped with hook 11, and the bottom end insertion of the hook 11 is arranged in pull rod It in 10, and is fixedly connected with pull rod 10, the hook 11 can be effectively attached with window top movable hook.

Further, rubber band 13 is equipped between the adjacent weldering patch 12, and the end of the rubber band 13 is pasted with weldering Second contact pin 4 and third contact pin 5 can be carried out elastic stretching, increase by second by piece 12 by strength glue bond, the rubber band 13 The cross directional stretch ability of contact pin 4 and third contact pin 5.

Further, the center of the shaft 2 is equipped with live bearing 14, and embedding be set on of the live bearing 14 turns On axis 2, and the bottom end of the spring 9 is fixedly connected with live bearing 14, and the spring 9 can pass through live bearing 14 and shaft 2 are rotated.

Working principle: firstly, respectively by the first contact pin 3, the circle at 6 top of the second contact pin 4, third contact pin 5 and the 4th contact pin The chirring of first 7 insertion curtain then needs to elongate bearing bar 8 when chirring is excessive, since the inside of shaft 2 is equipped with bull stick 15, Bull stick 15, which runs through, to be arranged in shaft 2, while the end of bull stick 15 is respectively embedded into and is arranged in bearing bar 8, so by bearing bar 8 Both ends be pulled outwardly, bull stick 15 can be elongated, while the length of bearing bar 8 also can be elongated, so that 3 He of the first contact pin in outside 4th contact pin 6 extends outwardly, and is inserted into excessive chirring convenient for facilitating, while the second contact pin of inside 4 and third contact pin 5 also can be outside Extend, but because rubber band 13 is flexible, the second contact pin 4 and third contact pin 5 can be made inwardly to apply pressure, so that curtain is clamped, Likewise, bearing bar 8 is inwardly squeezed, is tightened, hook 11 is finally hung over window if curtain chirring is too small On top movable hook, because the spring 9 of 11 bottom ends of hook has certain elasticity, without worrying that movable hook is too high or too It is low that hook 11 is caused not hang movable hook.
