Description
Technical field
The utility model relates to a kind of pivoting support.
Background technique
Use independent spacing block between the existing pivoting support roller, in work, spacing block can fall, and has been easy to the asphyxia by external pressure on the chest and abdomen phenomenon, and wearing-in period has been grown and has been easy to pulverize, and causes the damage of pivoting support.Reduce its working life.
Summary of the invention
The purpose of the utility model has been to provide a kind of pivoting support of long service life.
The utility model realizes that the technological scheme of above-mentioned purpose is, a kind of pivoting support comprises ring gear, outer ring and roller, and its innovative point is: also comprise retainer, said retainer has the pocket hole of equidistance on the said retainer between ring gear and outer ring.
Said retainer is whole or split.
The utility model uses retainer to replace original spacing block, and retainer is a massive structure, the asphyxia by external pressure on the chest and abdomen phenomenon can not occur, therefore makes prolong its working life.
Description of drawings
Fig. 1 is the plan view of the utility model;
Fig. 2 is the structural representation of the retainer of the utility model;
Fig. 3 is that the A of Fig. 2 is to schematic representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
Shown in Fig. 1 ~ 3, a kind of pivoting support comprises ring gear 1, outer ring 2 and roller 3, also comprises retainer 4, and said retainer 4 has the pocket hole of equidistance on the said retainer 4 between ring gear 1 and outer ring 2.
