Abstract
A supporting and limiting mechanism of a drawer sliding rail comprises at least one fixed sliding rail and at least one movable sliding rail, wherein the fixed sliding rail is in sliding connection with the movable sliding rail through a retainer, the fixed sliding rail is connected with a drawer cabinet body, the movable sliding rail is connected with a drawer base plate or a drawer side plate, the front end of the fixed sliding rail is provided with a supporting and limiting mechanism body, and the movable sliding rail is in sliding connection with the fixed sliding rail through the supporting and limiting mechanism body. The supporting and limiting mechanism body arranged at the front end of the fixed sliding rail comprises at least one rolling wheel seat wrapping the front end of the fixed sliding rail laterally and at least one rolling wheel arranged on the rolling wheel seat and connected with the fixed sliding rail and the movable sliding rail in a rolling mode. When a drawer is drawn out, the fixed sliding rail and the rolling wheel support the movable sliding rail through the retainer, the problem that a gap between the fixed sliding rail and the movable sliding rail is large, the fixed sliding rail and the movable sliding rail cannot be supported mutually, and accordingly sinking and deformation of the front end of the movable sliding rail, collision and friction between the front end and the fixed sliding rail and the like are caused is solved while the weight of the drawer is increased, and accordingly the drawer cannot swing laterally and shake vertically when drawn out and pushed into.
Description
Technical field
The present invention relates to a kind of drawer sliding rail, specifically is a kind of support limit mechanism of drawer sliding rail.
Background technology
Chinese patent literature CN202636185U discloses a kind of drawer guideway structure on January 2nd, 2013, comprise fixed track and movable rail, the supporting part of fixed track has the del cross section, and the cross section of movable rail roughly is n shape, between fixed track and the movable rail retainer is arranged; The horizontal sides upper surface of fixed track supporting part has first raceway of depression; The horizontal sides lower surface of movable rail also has second raceway of depression, and assembly has first ball between first raceway and second raceway; There is first bending part movable rail two upstanding edge lower ends; Two triangle hypotenuses with fixed track are relative respectively for two first bending parts of movable rail, and assembly has second ball respectively between the triangle hypotenuse of each first bending part and fixed track; First ball and second ball all are held frame and retrain.It is said that this is simple in structure, load capacity is big, it is little to rock, suitable being installed on all furniture used; But, because the length of retainer is shorter than the length of movable rail, so movable rail relative fixed rail is cantilever beam structures, load under the weight of object at drawer and drawer, the front end of drawer can sink to some extent, use the sinking degree all the more obvious for a long time, especially the drawer front end that sinks when drawer is closed fully shows that more drawer panel tilts, produce bigger space between the top and drawer cabinet of drawer panel, destroyed the attractive in appearance of furniture, simultaneously, also mutual friction phenomenon can occur between fixed track and the movable rail, cause the service life of drawer short.Therefore, be necessary further improvement.
Summary of the invention
