In figure: 1, the first chain sheet; 1-1, the first chain sheet plate; 1-2, the first sliding eye; 1-3, the second sliding eye; 2, the second chain sheet; 2-1, the second chain sheet plate; 2-2, the 3rd sliding eye; 2-3, the 4th sliding eye; 3, telescopic system is connected; 3-1, head rod; 3-2, the first linking springs; 3-3, the second connecting rod; 3-4, the second linking springs; 4, secondary chain sheet.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, to embodiment of the present utility model, effect and working principle etc. as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
As shown in Figure 1, the utility model provides a kind of chain with the anti-fall off chain of expansion device, comprise the first chain sheet 1, second chain sheet 2, connect telescopic system 3 and secondary chain sheet 4, connect telescopic system 3 by the first chain sheet 1, second chain sheet 2 and secondary chain sheet 4 couple together, first chain sheet 1 and secondary chain sheet 3 connecting part, second chain sheet 2 also with secondary chain sheet 4 connecting part, first chain sheet 1 comprises the first chain sheet plate 1-1, first sliding eye 1-2 and the second sliding eye 1-3, first sliding eye 1-2 and the second slip 1-3 hole are separately positioned on the two ends of the first chain sheet plate 1-1, first chain sheet 1 is connected with secondary chain sheet 4 by connecting telescopic system 3, connect telescopic system 3 and comprise head rod 3-1, first linking springs 3-2, second connecting rod 3-3 and the second linking springs 3-4, head rod 3-1 is connected with the second connecting rod 3-2 with the second linking springs 3-4 by the first linking springs 3-2, connect telescopic system 3 by head rod 3-1 and the second connecting rod 3-3 by the first chain sheet 1, second chain sheet 2 and secondary chain sheet 4 couple together, from inside to outside successively respectively by the first chain sheet 1 on head rod 3-1 and the second connecting rod 3-3, two secondary chain sheets 4 and the second chain sheet 2 couple together, second chain sheet 2 comprises the second chain sheet plate 2-1, 3rd sliding eye 2-2 and the 4th sliding eye 2-3, 3rd sliding eye 2-2 and the 4th sliding eye 2-3 is separately positioned on the two ends of the second chain sheet plate 2-1.
