Abstract
The utility model discloses a telescopic drag chain, which consists of an outer snap ring, an inner snap ring, a connecting shaft, a large supporting stop lever and a small supporting stop lever, wherein the outer snap ring is connected with the inner snap ring through the connecting shaft, and the outer snap ring is fixedly connected with the connecting shaft, the inner snap ring is movably connected with the connecting shaft, the large supporting stop lever is arranged inside the outer snap ring, and the small supporting stop lever is arranged inside the inner snap ring and penetrates through the ring frame of the inner snap ring to be positioned outside. The telescopic drag chain is high in tensile strength and crushing resistance, firm and telescopic, and is suitable for being applied to mine places of dragging heavy objects, and when not used, the drag chain can be contracted, so that half of the occupied space is reduced.
Description
Technical field
The utility model relates to a kind of scalable drag chain bar.
Background technique
Chain is a kind of interelement driving component of pivotable relatively flexibly, applies to each places such as bicycle, Motor Vehicle mining machinery, at present, some chains, in dilatory weight, easily fracture, insecure, can not shrink, there is now a kind of drag chain, can be used as dilatory weight, and can stretch, crushing resistance is strong, takes up room little.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of resistance to tension is provided, and crushing resistance is strong, and scalable strong, little scalable drag chain bar takes up room.
The utility model takes following technological scheme to realize: a kind of scalable drag chain bar, it is by outer snap ring, interior snap ring, coupling shaft, support pin and ramuscule support lever forms greatly, described outer snap ring links together by coupling shaft and interior snap ring, described outer snap ring is fixedly connected with coupling shaft, described interior snap ring is flexibly connected with coupling shaft, it is inner that described large support pin is arranged at outer snap ring, and it is inner that described ramuscule support lever is arranged at interior snap ring, and extremely outside through interior snap ring ring frame.
The ring frame two ends of described interior snap ring inside are provided with card.
The utlity model has in sum following beneficial effect: the resistance to tension of the utility model, crushing resistance is strong, and firmly, scalable, crushing resistance is strong, is applicable to applying to dilatory weight place, mine, and while not using, drag chain bar can shrink, and dwindles taking up room of half.
Accompanying drawing explanation
Fig. 1 is the utility model general structure block diagram;
Wherein: 1, outer snap ring; 2, interior snap ring; 3, coupling shaft; 4, support greatly pin; 5, ramuscule support lever.
Embodiment
As shown in Figure 1, a kind of scalable drag chain bar, it is by outer snap ring 1, interior snap ring 2, coupling shaft 3, support pin 4 and ramuscule support lever 5 forms greatly, described outer snap ring 1 links together by coupling shaft 3 and interior snap ring 2, described outer snap ring 1 is fixedly connected with coupling shaft 3, and described interior snap ring 2 is flexibly connected with coupling shaft 3, and described large support pin 4 is arranged at outer snap ring 1 inside, described ramuscule support lever 5 is arranged at interior snap ring 2 inside, and extremely outside through interior snap ring 2 ring frames.
The ring frame two ends of described interior snap ring 2 inside are provided with card.
Described interior snap ring 2 is flexibly connected with coupling shaft 3, and when not in use, interior snap ring 2 can advance in outer snap ring 1, until the large support lever 4 in the outer snap ring 1 of contact.
The above is the utility model embodiment, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
Claims (2)
