Embodiment Construction

[0012] see figure 1 and figure 2 A preferred embodiment of the ballless slide rail of the present invention includes a first rail body 20, a second rail body 40, a third rail body 60 and a number of positioning devices (not shown) arranged between the rail bodies. One rail body 20 can be fixed on a fixed object, such as a cabinet or a cabinet, the third rail body 60 is fixed on a side wall of a drawer or a server, and the second rail body 40 is accommodated in the first rail body 20 and the third rail body 60, the second rail body 40 and the third rail body 60 can slide relative to the first rail body 20 in the stretching or retracting direction, so as to pull the drawer / server out or push it into the cabinet / cabinet. The positioning device is arranged between adjacent rail bodies to prevent accidental sliding of the corresponding rail body. When the positioning device is in an unlocked state, the corresponding rail body can be stretched or retracted to slide.

Abstract

The invention relates to a sliding track without rolling balls, which comprises a first track body, a second track body assembled in the first track body and a third track body assembled in the second track body, wherein the second track body is positioned between the first track body and the third track body, the first track body and the second track body, as well as the second track body and the third track body, are respectively in curved surface-shaped direct contact, the second track body comprises an upper arm and a lower arm, which are symmetrically arranged, each one of the upper arm and the lower arm comprises a first kinked part, a second kinked part, a third kinked part and a fourth kinked part, which are sequentially connected, arc-shaped first sliding parts are respectively formed on the edges of the junctions between the second kinked parts and the first kinked parts and in sliding contact with the third track body, and arc-shaped second sliding parts are respectively formed on the edges of the junctions between the fourth kinked parts and the third kinked parts and are in sliding contact with the first track body. All the track bodies of the sliding track without the rolling balls of the application are in curved surface-shaped direct contact, thereby not only reducing the use of the rolling balls and other elements and saving the cost, but also being firm in structure, being strong in bearing capacity and being labor-saving to slide.

Description

technical field [0001] The invention relates to a ballless slide rail. Background technique [0002] In order to reduce the resistance when the drawer is pulled, ball racks and balls are installed between the rail bodies of the general drawer slide rails. The ball slide rail is easy to push and pull, but the cost is high, and components such as the ball frame and balls are easily damaged, so that the ball slide rail cannot continue to be used. Contents of the invention [0003] In view of the above, it is necessary to provide a non-ball slide rail that is easy to pull. [0004] A ballless slide rail, comprising a first rail body, a second rail body installed in the first rail body and a third rail body installed in the second rail body, the second rail body is located at the Between the first rail body and the third rail body, the first rail body and the second rail body, and the second rail body and the third rail body are in direct contact with each other in the shape ...
