Embodiment Construction
[0028] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0029] like figure 1 As shown in the drawing, the surface rail 21 and the bottom rail 11 of the drawer involved in the present invention are square tubes with half-surface openings, in the form of a groove, with three and a half surfaces on the entire four-surface, leaving half-surface slits, so that the surface rail 21 and the bottom rail 11 can be mutually Buckle socket. A roller sliding bearing assembly 12 is arranged between the interlocking (overlapping) parts of the surface rail 21 and the bottom rail 11. The roller sliding bearing assembly 12 includes a wheel frame 15 and a plurality of rollers 16 installed on the wheel frame 15, so that the bottom rail 11 can support The surface rails 21 can slide flexibly relative to each other. The roller sliding support assembly 12 must be located between the overlapping sections of the surface ra...

The invention discloses a two-section full-expansion drawer slide rail, which comprises a bottom rail fixedly connected with the inner side of a cabinet side panel, a surface rail slidably installed on the bottom rail, and a roller located between the bottom rail and the surface rail The sliding bearing assembly, the cladding shell that buckles and covers the top and both sides of the surface rail and is fixedly connected with the drawer box, and the two supporting wheels that are vertically installed on the side of the surface rail and support the cladding shell, the cladding shell The inner top surface of the cabinet is provided with a wheel groove or an angular step which is offset to the side panel of the cabinet and is rolled against the bearing wheel along its length direction. By setting a supporting wheel between the surface rail and the covering shell, the covering shell can further slide a certain distance on the basis of the sliding of the surface rail, so that the drawer can be fully expanded, which is convenient for taking and placing items. Improve coordination stability. Wheel slot offsets to match the extra narrow trim shell of the drawer.
Description
technical field [0001] The invention relates to a drawer slide rail, in particular to a two-section full-expansion drawer slide rail. Background technique [0002] The current drawer installation is mostly in two forms. One is to directly slide and rub into the drawer frame of the cabinet or table. During the process of pulling and pushing, the drawer and the frame rub against each other, which will cause wear and tear over time. There is also a certain noise in normal use, which is not suitable. It is used in a large area office, which has higher requirements on the drawer material, and the drawer will be inclined after being pulled out, which is not conducive to the neat placement of items; the other is to install slide rails and drawer frames on both sides of the drawer, the drawer can be Smooth and not inclined and low noise, small friction and less wear. [0003] The sliding rail drawer has a simple form, which slides through the overlapping and matching of the wheel r...
