Anti-derailment structure of sliding door

[0024] Example one:

[0025] Such as figure 2 , 3 As shown, the present invention provides a sliding door structure, which includes two uprights 7 with a beam 1 between the two uprights. A fixed door 8 and a movable door 5 are provided between the two uprights 1. The fixed door 8 is fixedly connected to one of the door posts 7, and the movable door 5 is connected to the hanging wheel 2 through the connecting piece 4, and the hanging wheel 2 is arranged on the slide rail 3. On the upper side, the slide rail 3 is fixed on the beam 1, and the hanging wheel 2 can slide back and forth along the slide rail 3 to realize the opening and closing of the movable door. As a preferred embodiment, the hanging wheel 2 can be connected with the driving mechanism 9 through a connecting device, and the movable door 5 can be automatically moved by the driving mechanism 9. As a specific embodiment, the driving mechanism 9 may adopt a structure of a motor and a conveyor belt, the conveyor belt is conn

[0027] Embodiment two:

[0028] Such as Figure 4 As shown, the difference between this embodiment and the first embodiment is that there is no limit rod 10 between the two door posts 7, but the lower end of the cover 6 is directly extended to the front side of the movable door 5. The movable door 5 is restricted by the cover 6 directly. The limit structure of the cover 6 can be designed according to the actual situation, and an inward flanging can be provided at the lower end 61 of the cover, or the limit can be directly performed by the cover 6. A gap should be provided between the lower end of the cover 6 and the movable door 5, and the gap size should be smaller than the displacement amount of the hanging wheel 2 on the sliding rail 3 sliding out of the sliding rail 3 laterally.

[0029] Embodiment three:

[0030] Such as Figure 5 As shown, the difference between this embodiment and the first and second embodiments is that this embodiment is directly provided with a limit post 11 on the connecting piece 4 of the hanging wheel 2. Since the connecting piece 4 is also arranged in the cover 6, this The connecting member 4 can be directly limited by the gap between the limiting post 11 and the cover 6 so as to achieve the purpose of limiting the hanging wheel 2. In order to prevent the limit post 11 from hitting the cover 6 for multiple times and cause damage to the cover, a rubber pad 12 can be provided at the outer end of the limit post 11, and a gap is provided between the rubber pad 12 and the cover 6. The inner end of the limiting column 11 is threadedly connected with the connecting member 4, so that it is convenient to adjust the size and distance of the gap by rotating the limiting column 11.
