Summary of the invention
The technical problems to be solved in the utility model provides the preferably retainer assembly of drawer guideway of a kind of combination property, and this retainer assembly has preferably stability, wearability and less frictional resistance simultaneously.
The technical scheme that the utility model solves the problems of the technologies described above is:
A kind of retainer assembly of drawer guideway, formed by retainer and rolling element, wherein, described retainer by two holding units that are positioned at two and the bridging piece of connection two holding units in the middle of being positioned at consist of, wherein, described holding unit is formed by connecting by top board and two flanks, is equipped with a plurality of rolling element mounting grooves on described top board and each flank, and the rolling element of wherein installing on the rolling element mounting groove on the flank is ball; It is characterized in that the rolling element of installing on the rolling element mounting groove on the described top board has a ball and a roller at least.
As a preferred version of the present utility model, described each top board is provided with four rolling element mounting grooves, and wherein, a rolling element mounting groove that is positioned at the outer end is installed roller, and ball is installed in other three rolling element mounting grooves.
As a preferred version of the present utility model, described each top board is provided with four rolling element mounting grooves, and wherein, the rolling element mounting groove that is positioned at two ends is installed ball, and roller is installed in two other rolling element mounting groove.
A more concrete scheme of the present utility model, wherein, the rolling element mounting groove on the described flank be opening towards under groove, the two sides of this groove are provided with the recess for the location ball, described ball is clamped between two recesses.
The utility model compared with prior art has following technique effect:
In the retainer assembly, the gravity of drawer is mainly born by the rolling element on the top board, the frictional force that produces in the drawer drawing process also Main Function on these rolling elements, and the existing ball of rolling element on the top board also has roller in the retainer assembly of the present utility model, therefore drawer both had preferably stability because of the existence that roller is arranged in sliding process, also has preferably wearability and less frictional resistance because of the existence that ball is arranged, therefore retainer assembly of the present utility model has good combination property, the beneficial effect of long service life.
