In the assembled condition, when the tail connecting portion of a upper carrier bar is rotatablely connected with the first connecting portion of next carrier bar,
Two protruding shafts in next carrier bar head connecting portions are correspondingly embedded in the waist-shaped hole of a carrier bar tail connecting portion respectively, pass through waist
The hole axle of type hole and protruding shaft coordinates, and realizes rotation guiding between two neighboring carrier bar.
Relevant content in above-mentioned technical proposal is explained as follows：
1st, in such scheme, on the tail connecting portion, between at least two waist-shaped holes, a first through hole is offered；
On the first connecting portion, between at least two protruding shafts, one second through hole is offered.
2nd, in such scheme, a upper chain is realized by the bearing pin plugged simultaneously between the first through hole and the second through hole
The rotation connection of plate and next carrier bar.
3rd, it is spaced apart in such scheme, on the tail connecting portion along in carrier bar rotation direction and is provided with two waist-shaped holes, it is described
Two protruding shafts are correspondingly provided with first connecting portion.
4th, in such scheme, described protruding shaft is a hole axle that punching stretching is formed on metallic plate chip drag chain carrier bar.
5th, in such scheme, on the plate body bottom surface, the side bending opposite with the protruding shaft protrusion direction forms a piece of
Shape structure, under drag chain confined state, the most bottom surface of the laminated structure is less than the most bottom surface of cross bar in each chain link.
6th, in such scheme, the tail connecting portion and first connecting portion of the carrier bar are the difference life to two parts on carrier bar
Name, the tail connecting portion and first connecting portion can be exchanged in practice.
Utility model works principle is：Single shaft gold-sprinkled category plate-sheet-type drag chain carrier bar of the present utility model, in tail connecting portion
On along in carrier bar rotation direction uniform intervals offer at least two waist-shaped holes, corresponded on first connecting portion uniform intervals be provided with extremely
Few two protruding shafts；In the assembled condition, when the tail connecting portion of a upper carrier bar and the first connecting portion of next carrier bar are rotatablely connected
When, two protruding shafts in next carrier bar head connecting portions are correspondingly embedded in the waist-shaped hole of a carrier bar tail connecting portion respectively, are led to
The hole axle for crossing waist-shaped hole and protruding shaft coordinates, and so as to realize, rotation is oriented between two neighboring carrier bar.
Because above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：
The utility model is simple in construction, parts are few, good reliability, can be reduced on the premise of drag chain intensity is ensured
The weight of half, reduce cost.
