In order to have a further understanding and understanding of the purpose, characteristics and effects of the present utility model, please refer to the accompanying drawings and examples below, and the detailed description is as follows: 

First of all, please refer to Fig. 1 and Fig. 2, a curtain body structure without a pull cord, which includes: a main rail 10, a secondary rail 20, a curtain body 30 and a rope body 40, a main One side of the rail 10 is opened horizontally with a slot 11, and an upper slide rail 12 is provided inside, and one side of the auxiliary rail 20 is opened with a slot 21 horizontally, and a lower rail 22 is provided inside. The inner space of 20 is provided with corresponding limiting parts 23 on the left and right sides respectively, and an elastic rope 24 is provided to bypass the limiting parts 23 with the ends of both sides respectively, and a connecting piece 25 is tied at the ends respectively, And the slots 11, 21 of the main and auxiliary rails 10, 20 are respectively provided with covers 111, 211 to cover and limit, and the covers 211 configured on both sides of the auxiliary rail 20 can also extend from the bottom surface to an upright Through the rod 212, the limit part 23 is set on the through rod 212 to form a positioning (as shown in Figure 3). 20 sets of connections, wherein the upper and lower ends of the curtain body 30 are respectively provided with a connecting plate 31, to form a limit in the upper slide rail 12 and the lower slide rail 22 that respectively extend through the main rail bar 10 and the auxiliary rail bar 20, and The curtain body 30 is provided with two through holes 32 from top to bottom. A rope body 40 is wound between the two connecting parts 25 for several turns. The through hole 32 (please refer to Fig. 4 and Fig. 5 at the same time) is tied and fixed on the upper end of the curtain body 30 to form a connection. the

For the composition of its structure, please refer to Fig. 2 and shown in Fig. 4, Fig. 5 and Fig. 6, an elastic cord 24 is provided inside the secondary rail bar 20 to bypass the stopper 23 at both ends, and connect the two ends respectively. The matching group is provided with a connecting piece 25, and the rope body 40 is to be wound between the two connecting pieces 25 at the middle section, then get the same length from both sides and intersect with each other and then penetrate through the two through holes 32 of the curtain body 30, and wear After the curtain body 30 is tied and fixed to form a connection, finally a connecting plate 31 is respectively assembled at both ends of the curtain body 30, respectively penetrated into the upper rail 12 and the lower rail 22 of the main rail 10 and the auxiliary rail 20 to form a limit rail. position, and provide covers 111, 211 to cover and set on both sides of the slots 11, 21 of the main and auxiliary rails 10, 20 respectively. By the above structure, a curtain structure without a pull cord can be completed. the

For the use of its structure, please refer to Fig. 4 and Fig. 7 in conjunction with Fig. 8 and Fig. 9. When the curtain is not unfolded for use, its rope body 40 is stretched by the elastic cord 24 to be wound and collected between the two connecting parts 25, and Shorten the length of the rope body 40 between the curtain body 30, and when the curtain body 30 is to be expanded to form a light-shielding state, that is, the main rail 10 or the auxiliary rail 20 is pressed and pulled down, so that the curtain body 30 is unfolded and the rope body 40 is taken advantage of the situation. It is pulled out from the auxiliary rail 20, and the rope body 40 is connected by the connecting piece 25 and the elastic rope 24, and the rope body 40 and the connecting piece 25 are wound and first interlaced and then penetrated into the through hole 32 of the curtain body 30, so as to When the rope body 40 is pulled out and extended with the curtain body 30 unfolding, the two connecting parts 25 are moved towards the central place synchronously, and the elastic rope 24 is elastically stretched due to the displacement concentration of the two connecting parts 25, and the main rail bar 10 Or the vertical gravity of the auxiliary rail 20 is positioned by the rope body 40 being wound between the connecting parts 25 and the elastic interference of the elastic rope 24 , that is, the unfolded state is formed. the

Conversely, when the curtain body 30 is to be folded and positioned, the main rail 10 or the auxiliary rail 20 is pushed upward, and the rope body 40 will be lowered due to the vertical gravity of the main rail 10 or the auxiliary rail 20. and loosen, and the elastic reset of the elastic rope 24 will displace the two link parts 25 to the two outer sides respectively, so that the rope body 40 is recovered and concentrated between the two link parts 15, and is limited by the elastic rope 24 to prevent the rope body 40 from being damaged. The weight of the main rail 10 or the auxiliary rail 20 is pulled out, and prevents the curtain body 30 from unfolding without force, so as to form a folded state. the

From the structure of the above-mentioned specific embodiment, the following benefits can be obtained: the main rail bar 10, the auxiliary rail bar 20 and the curtain body 30 of the present utility model are connected in series and linked by the rope body 40 and the elastic rope 24, so that the structure The cost is low and the assembly is simple and convenient, and the rope body 40 is first wound between the two connecting parts 25 and positioned by the restriction of the elastic rope 24. All are limited by the interference of the elastic cord 24 to achieve the action without a pull cord, effectively reducing the sound generated by the opening and cooperation of the curtain body 30, so as to increase the quality of life in the home environment. the

The above is only a preferred embodiment of the present utility model, and should not limit the scope of the present utility model implementation; within the scope covered by the utility model claims. the
