Both ends of the inner rail are connected to the outer rail one and the outer rail two respectively through a connecting mechanism. The connecting mechanism includes a fixing seat, a rivet, and an elastic stop block. The elastic stop block is fixed to the inner rail by the rivet, and a lever is provided on the elastic stop block. Both the outer rail one and the outer rail two have openings, and the fixing seat is fastened to the opening. An extension block is provided on the fixing seat.
[0006] Preferably, the outer rail 1 and outer rail 2 are provided with a plurality of sliding grooves 1, and a slider 1 is provided inside one of the sliding grooves 1. The inner rail is provided with a plurality of sliding grooves 2, and a slider 2 is provided inside both of the sliding grooves 2.
[0007] Preferably, both slider one and slider two are provided with screen curtains.
[0008] Preferably, both slider one and slider two are provided with pulleys.
[0009] Preferably, both outer rail one and outer rail two are made of metal.
[0010] Preferably, the inner rail is also provided with a mounting plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] (1) This utility model is a telescopic screen curtain. By setting the screen curtain to a telescopic structure, the track length can be doubled, which is suitable for any windowsill and can also significantly reduce transportation costs.
[0013] (2) This utility model is a telescopic screen curtain.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] Example
[0025] Please see Figure 1-8 This utility model proposes a technical solution for a telescopic screen curtain: a telescopic screen curtain includes an outer rail 1 and an outer rail 2, with an inner rail 3 disposed between the outer rail 1 and the outer rail 2. An end cap 4 is disposed at the end of the outer rail 1 and the outer rail 2 away from the inner rail 3. Specifically, the end cap 4 is used to prevent parts from sliding off the outer rail 1 or the outer rail 2. Both ends of the inner rail 3 are connected to the outer rail 1 and the outer rail 2 respectively via a connecting mechanism. The connecting mechanism includes a fixing seat 5, a rivet 6, and an elastic stop 7. The elastic stop 7 is fixed to the inner rail 3 by the rivet 6, and a lever 8 is disposed on the elastic stop 7. Both outer rail 1 and outer rail 2 have openings 9. The fixing seat 5 is fastened to the opening 9. The fixing seat 5 is provided with a protruding block 10. Specifically, the fixing seat 5 is fixed to the opening 9, and the elastic stop 7 can rotate flexibly. During assembly, the elastic stop 7 is squeezed and deformed, and the two ends of the inner rail 3 are respectively inserted into the interior of outer rail 1 and outer rail 2. When the size is pulled to the maximum, the protruding block 10 on the fixing seat 5 contacts the elastic stop 7, preventing the inner rail 3 from detaching. When it is necessary for the inner rail 3 to detach from outer rail 1 or outer rail 2, press the lever 8 of the elastic stop 7 to detach the inner rail 3 from outer rail 1 or outer rail 2 respectively.
[0026] Please see Figure 8 As shown, further, a number of sliding grooves are provided on the outer rail 1 and the outer rail 2, and a slider 11 is provided inside the sliding groove 1. A number of sliding grooves are provided on the inner rail 3, and a slider 22 is provided inside the two sliding grooves 2.
[0027] In this embodiment, slider 11 can move within slide groove 1, and slider 2 12 can move within slide groove 2.
[0028] Please see Figure 1 As shown, both slider 11 and slider 2 are further provided with screen curtains 13.
[0029] In this embodiment,
[0030] Please see Figure 6 As shown, both slider 11 and slider 2 12 are further provided with pulleys 14.
[0031] In this embodiment, the stability of the sliding connection is effectively improved by setting the pulley 14.
[0032] Furthermore, both outer rail 1 and outer rail 2 are made of metal.
[0033] In this embodiment, both outer rail 1 and outer rail 2 are made of aluminum alloy to extend their service life.
[0034] Please see Figure 1As shown, an mounting plate 15 is further provided on the inner rail 3.
[0035] In this embodiment, the mounting plate 15 is disposed on the top of the inner rail 3 to facilitate the installation of the inner rail 3.
[0036] The working principle of this utility model:
[0037] During assembly, the elastic stop 7 is compressed and deformed, inserting both ends of the inner rail 3 into the interior of the outer rail 1 and the outer rail 2 respectively; when the size is stretched to the maximum, the protruding block 10 on the fixed seat 5 contacts the elastic stop 7, preventing the inner rail 3 from detaching.
[0038] When it is necessary for the inner rail 3 to disengage from the outer rail 1 or outer rail 2, press the lever 8 of the elastic stop block 7.
[0039] The inner rail 3 can then be separated from the outer rail 1 or the outer rail 2 respectively.
[0040] This utility model adopts a telescopic structure, which can double the track length, making it suitable for any windowsill, while also significantly reducing transportation costs. By adopting a detachable stop design, it solves the problem that existing telescopic screen curtain fixed stop designs on the market cannot be freely combined, making it highly practical and convenient for maintenance and disassembly.
