Specific embodiment

The application is described in further detail in the following with reference to the drawings and specific embodiments.It should be appreciated that following signal Property embodiment and explanation be only used for explaining the utility model, be not intended to limit the scope of the present invention, moreover, not conflicting In the case of, the feature in embodiment and embodiment in the application can be combined with each other.

As shown in Figure 1 to Figure 3, the utility model one embodiment provides a kind of curtain take-up and pay-off device reel, including The inside of axis 1 and the end plate 2 that 1 both ends of axis are axially set in perpendicular to axis 1,1 lateral surface of axis and two end plates 2 Face cooperatively forms winding space（The non-label of figure）, the winding space is in 1 lateral surface of axis close to the end of 1 first end of axis It is equipped at plate 2 for 3 one rear line head of fixed pulling rope（The non-label of figure）The end of a thread bayonet 11, the axis 1 is equipped with described the end of a thread One end of bayonet 11 is additionally provided with using the side of the end of a thread bayonet 11 as starting point and along axis 1 circumferentially around to positioned at the line The conducting wire bulge loop 12 of the terminating point of the opposite opposite side of head bayonet 11, the conducting wire bulge loop 12 and the end plate 2 of first end are linked to be one The width of body and conducting wire bulge loop 12 in 1 axial direction of axis gradually smoothly increases, and conducting wire from the starting point to the terminating point Bulge loop 12 matches in the difference of the width of starting point and the width of terminating point and the diameter of drawstring 3, specifically, the width it The diameter of difference and drawstring 3 has a smaller difference, and the difference of the width can be equal to, slightly smaller than or the diameter slightly larger than drawstring 3； The conducting wire bulge loop 12 matches in the thickness of axis radially with 3 diameter of drawstring.

End plate 2 of the present embodiment by axis 1 and set on 1 both ends of axis cooperatively forms winding space and the winding space The end of a thread bayonet 11 is set at the end plate 2 close to 1 first end of axis with 3 one rear line head of fixed pulling rope, the axis 1 is additionally provided with edge Axis 1 circumferentially around and starting point and ending point be respectively arranged on the conducting wire bulge loops 12 of 11 both sides of the end of a thread bayonet, conducting wire bulge loop 12 exists Width in 1 axial direction of axis is from starting point to terminating point gradually smoothly increase and the difference of width between starting point and terminating point etc. In the diameter of drawstring 3, drawstring 3 is made to fill up the gap that the second circle drawstring 3 reserves at the end of a thread of drawstring 3 when winding axis 1（Figure Non- label）, drawstring 3 wind neat compact, can effectively avoid when drawstring 3 is wound with multilayer, second layer drawstring 3 be absorbed in first layer drawing In the gap that rope 3 is reserved in the end of a thread, drawstring 3 is made coiling out-of-flatness occur, and then drawstring 3 is made to tangle chaotic, reel folding and unfolding not The situation of smooth or even stuck reel, reel operation is more smooth, realizes the folding of curtain.

In one alternate embodiment, the conducting wire bulge loop 12 is located at the width of the starting point and the starting point The distance of 2 medial surface of end plate of the end of a thread bayonet 11 to first end match.By by the width of the starting point of conducting wire bulge loop 12 Be arranged to it is equal with the distance of 2 medial surface of the end plate of the end of a thread bayonet 11 to first end, at the end of a thread for making conducting wire bulge loop 12 and drawstring 3 It fits closely, the coiling fluency of reel can be effectively improved.

In one alternate embodiment, the axis 1 is hollow shaft, and the end of a thread bayonet 11 is included by the starting point one Side and with the hollow space of axis 1（The non-label of figure）It connects so that the end of a thread of drawstring 3 is passed into the hollow space of axis 1 Card hole 111, aperture and 3 diameter of drawstring of the card hole 111 match.

In a specific embodiment, the axis 1 includes the outer shaft 13 for coiling and the interior and and axis set on outer shaft 13 It holds（It is not shown）The inner shaft 14 of corresponding adaptation, is attached between the outer shaft 13 and inner shaft 14 by stent 15, described outer The inner surface of axis 13 forms hollow space with the inner surface of inner shaft 14.

The present embodiment is by the way that axis 1 to be set as hollow shaft and be equipped at the end of a thread bayonet 11 to match with the diameter of drawstring 3 Card hole 111 so that the end of a thread of drawstring 3 passes through and blocks drawstring 3, make the assembling between drawstring 3 and axis 1 simpler reliable.

In one alternate embodiment, the end of a thread bayonet 11 further include by the terminating point side and in axis 1 The absolutely empty handle hole 112 to connect, the handle hole 112 are more than the outer diameter of knot that 3 one rear line head of drawstring is formed by knots tied, institute It states card hole 111 and is connected with handle hole 112 and is additionally provided in connectivity part and be moved to handle hole from card hole 111 for limiting drawstring 3 Limit protrusion 113 in 112.

In the specific implementation, first, a rear line head of drawstring 3 from card hole 111 is penetrated to the inner space of axis 1, and is led to It crosses handle hole 112 and the end of a thread pull-out of drawstring is formed by knots tied knot, the diameter of the knot is more than the internal diameter of card hole 111 and is less than The internal diameter of handle hole 112；Then, knot is passed through into handle hole 112 into the hollow space of axis 1；Then again by pulling Rope 3, which is located at 111 lateral ends of card hole, makes knot be moved to 111 inside of card hole, because the internal diameter of card hole 111 is less than the diameter of knot So that drawstring 3 be stuck it is fixed without being detached from away from card hole 111, drawstring 3 can be wound at this time reel around In space of lines.On the other hand, when needing to disassemble drawstring 3 from reel, the drawing that will first be wrapped in winding space Rope is split out, and can be taken out drawstring 3 from handle hole 112 and be opened knot（Or directly wipe out knot）, you can by drawstring 3 completely from card hole It is pulled out in 111.The design of the end of a thread bayonet 11 easily can be fixed and dismantle to drawstring 3, improve the utility model curtain and receive The practicability of actinobacillus device reel.

In one alternate embodiment, the end plate 2 is circular ring shape plate, and the outer edge surface of wherein at least one end plate 2 For face of gear.By the way that the outer edge surface of at least one of end plate 2 is set as face of gear, convenient and other transmission mechanisms（It is not shown Go out）Connection so as to reel be driven to rotate to realize automatic takeup or unwrapping wire by transmission mechanism, improves the practicality of reel Property.

Particular embodiments described above has carried out into one the purpose of this utility model, technical solution and advantageous effect Step is described in detail, it should be understood that the foregoing is merely specific embodiment of the utility model, is not used to limit this The protection domain of utility model, within the spirit and principle of the utility model, any modification for being made, changes equivalent replacement Into etc., it should be included within the scope of protection of this utility model.
