DETAILED DESCRIPTION
[0023] The utility model provides a guide rail structure for preventing a lifting window from falling. Figure 1-4 As shown, it includes a steel groove 1 and a slider 2, the steel groove 1 is installed and fixed to the window frame, the slider 2 is slidably connected in the steel groove 1, and the inner side of the slider 2 is connected to the lifting window: the cross-section of the steel groove 1 is C-shaped, and the steel groove 1 has a sliding groove. The slider 2 is divided into a sliding part 21 and a connecting part 22, the sliding part 21 slides in the sliding groove, and the connecting part 22 is connected to the lifting window. The sliding part 21 is hinged to a pair of supporting legs 3 at the upper and lower ends, and the ends of the supporting legs 3 are rotatably connected to pulleys 4. Springs 5 are connected between the supporting legs 3. Anti-falling grooves 6 are opened on both sides of the lower end of the steel groove 1. The slider 2 slides downward to a limited position, and the pair of supporting legs 3 at the lower end of the sliding part 21 are stuck in the anti-falling grooves 6 to prevent the slider 2 from falling further.
[0024] In the above technical solution, if Figure 2 As shown, the shape of the sliding groove of the steel groove 1 can accommodate the sliding part 21 therein to prevent it from detaching; further, a pair of supporting legs 3 elastically arranged above and below the sliding part 21 can make the upper and lower supporting legs 3 expand outward to apply force to the two sides of the steel groove 1, so that the sliding part 21 can just slide in the steel groove 1 to prevent it from derailing.
[0025] Furthermore, in the above technical solution, a guide wheel 7 is rotatably connected to the upper opening of the anti-fall groove 6, so that when the slider 2 moves upward, the lower end support leg 3 contracts inwardly, does not hinder the sliding part 21 from moving upward again, and does not hinder the normal use of the lifting window.
[0026] like Figure 3 As shown, a limiting column 8 is provided on the connecting plate outside the supporting leg 3 to limit the pair of supporting legs 3 from further turning outward, so that the supporting effect is more prominent.
[0027] like Figure 1 As shown, the sliding part 21 is connected to the connecting part 22 via a connecting column 9. The connecting part 22 has a U-shaped cross section and is provided with a mounting hole 10 for fixing to a lifting fan (a lifting window is not shown in the figure).
[0028] In a preferred embodiment, in order to make the sliding part 21 slide more smoothly in the steel groove 1 and reduce the friction resistance, a plurality of rollers 11 are linearly rotatably connected to both side surfaces and the front side surface of the sliding part 21 .
[0029] The second anti-falling implementation measure is that a limit block 12 is installed at the lower end of the inner side of the steel trough 1, and the upper end of the limit block 12 prevents the slide block 2 from sliding further down.
[0030] The third anti-falling implementation measure is that a connecting ring 13 is installed on the connecting part 22, and the upper end of the steel trough 1 is covered with an upper cover 14, and a connecting hole is provided on the upper cover 14, and a connecting safety rope is passed between the connecting ring 13 and the connecting hole.
[0031] Working principle: When installing the anti-fall guide rail structure, the steel groove 1 can be first fixed to the inner side of the window frame, such as by fasteners. Figure 2 As shown, when sliding the slider 2 from the upper end of the steel channel 1, when installing the slider 2, it is necessary to manually press the lower end support leg 3 and the upper end support leg 3 respectively, so that the support leg 3 is contracted inwardly and accommodated in the steel channel 1. Under the action of the elastic force of the spring 5, the upper and lower end support legs 3 generate an outward expansion force, thereby improving the safety of the sliding part 21 in the steel channel 1, and the connecting part 22 is fixedly connected to the side frame of the lifting window, and a safety rope is arranged between the connecting ring 13 and the connecting hole;
[0032] When the slider 2 slides down to the limit position, the lower support leg 3 will slide into the anti-falling groove 6 to form a stable triangular structure, preventing the slider 2 from sliding down further, thereby preventing it from falling. At the same time, the limit block 12 and the safety rope play an auxiliary role in protection.
[0033] When the slide block 2 needs to be moved up again, the lower end support leg 3 can slide smoothly into the steel groove 1 under the action of the guide wheel 7 at the upper opening of the anti-fall groove 6, without hindering the normal use of the lifting window.
[0034] To sum up, in the anti-falling guide rail structure of the lifting window, the slider 2 is divided into a sliding part 21 and a connecting part 22, a pair of supporting legs 3 are hinged at the upper and lower ends of the sliding part 21, a spring 5 is arranged between the supporting legs 3, and the ends of the supporting legs 3 are rotatably connected to the pulley 4. Under the elastic force of the spring 5, the upper and lower pairs of supporting legs 3 generate an outward force, so that the sliding part 21 slides and is clamped in the sliding groove of the steel groove 1, which plays a good supporting role; in the anti-falling guide rail structure of the lifting window, anti-falling grooves 6 are provided on both sides of the lower end of the steel groove 1. When the pulley 4 slides down to a limited position, the lower end supporting leg 3 will slide into the anti-falling groove 6 to prevent the pulley 4 from further sliding down, effectively preventing the pulley 4 from derailing and preventing the lifting window from falling.
[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
