[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] Specific embodiments are given below

[0028] See also Figure 1-Figure 5The utility model discloses a curtain folding telescopic rail, comprising two sets of rails 1, the two sets of rails 1 are rotatably connected by a ratchet rotating component, a telescopic rail 2 is movably inserted in the rails 1, a plurality of roller components 3 are arranged in the rails 1 and the telescopic rails 2, the roller components 3 include a connecting rod 301 and rollers 302 rotatably arranged at both ends of the connecting rod 301 through bearings, a hanging part 4 is fixedly mounted on the connecting rod 301, a hanging hole 5 is opened on the hanging part 4, a fixing mechanism 100 is mounted on the telescopic rail 2, the The fixing mechanism 100 is used to fix the sleeve rail 1 and the telescopic rail 2. The fixing mechanism 100 includes a movable sleeve 6 slidably sleeved on the telescopic rail 2. A plug 7 is fixedly provided on one side of the movable sleeve 6. The plug 7 is provided with an array of abutment portions 701 through a groove 8. The array of abutment portions 701 is in a slope structure, and the height of the abutment portion 701 away from the position of the movable sleeve 6 to the abutment portion 701 close to the position of the movable sleeve 6 is gradually increased. When working, when the curtain folding telescopic rail is installed, the user first rotates the two The two sets of rails 1 are arranged to stretch out, and the two ends of the two sets of rails 1 are arranged in a staggered manner. This design can make the curtains cross when closed to prevent light leakage. Then the telescopic rails 2 are pulled out, and the extension length of the telescopic rails 2 is adjusted according to the installation distance. Then the user moves the movable sleeve 6 to insert the insert 7 into the corresponding groove opened on the rail 1. The insert 7 has resistance when inserting because the thickness of the insert 7 is greater than the thickness between the groove and the telescopic rail 2. The abutment parts 701 with different heights on the insert 7 abut against the outer wall of the telescopic rail 2, so that the friction between the two Gradually increase to fix the telescopic rail 2 and the sleeve rail 1. Conversely, when the extension amount of the telescopic rail 2 needs to be adjusted again, the movable sleeve 6 can be pulled out to adjust it. Such a fixing structure is simple and easy to use. The entire curtain folding telescopic rail is fixed to the curtain installation position through an external fixing component, and then the hook on the curtain is passed through the hanging hole 5 on the hanger 4, and the curtain is assembled, that is, the installation is completed. The curtain can be opened and closed by pulling the curtain. When the curtain is pulled, it will drive a number of roller components 3 to move, and the roller components 3 make the sliding of the curtain smoother.

[0029] Furthermore, one end of the telescopic rail 2 is assembled with an end cover 9 through a snap buckle. During operation, when assembling the curtain folding telescopic rail, it is necessary to assemble several roller components 3 into the sleeve rail 1 and the telescopic rail 2, open the end cover 9 and assemble it inside, and then cover the end cover 9 to complete the assembly. The structure is simple and reliable.

[0030] Furthermore, a gentle slope 10 is provided at one end of the telescopic rail 2 close to the sleeve rail 1. When in operation, the telescopic rail 2 is inside the sleeve rail 1, and the path of the roller 302 is formed by the combination of the telescopic rail 2 and the sleeve rail 1. The gentle slope 10 allows the roller 302 to move more smoothly when it reaches the intersection of the sleeve rail 1 and the telescopic rail 2, thereby ensuring that the roller 302 does not get stuck when rolling.

[0031] Furthermore, a first limit block 11 is fixedly provided at one end of the telescopic rail 2 located inside the sleeve rail 1, and a second limit block 12 is fixedly provided at one end inside the sleeve rail 1. When in operation, the movable range of the telescopic rail 2 in the sleeve rail 1 is limited by the first limit block 11 and the second limit block 12 to prevent the telescopic rail 2 from detaching from the sleeve rail 1.

[0032] Furthermore, the structures of the sleeve rail 1 and the telescopic rail 2 are both in an inverted concave shape. When working, since the sleeve rail 1 and the telescopic rail 2 are set in an inverted concave shape, such a structure greatly reduces dust from entering and accumulating therein.

[0033] Furthermore, rubber is provided on the outer circumferential contact surface of the roller 302. When the curtain is in operation, the rubber provided on the roller 302 makes the roller 302 quieter when the curtain is pulled, thereby greatly improving the user experience.
