Description

TECHNICAL FIELD

[0001] The utility model belongs to slide rail mechanism technical field, especially a hidden slide rail can let the user adjust the tension to bear different weight. BACKGROUND

[0002] The slide rail is a common connecting piece, and is mainly composed of a pulley, a spring, a damper and a track. The slide rail is assembled on a drawer, so that the drawer can be selectively pulled out or pushed into a cabinet.

[0003] However, when the drawer is pushed into the cabinet, the spring tension generated by the spring is fixed and cannot be adjusted. When the drawer carries a large amount of articles, the load of the slide rail is too large, so that the spring tension is insufficient, causing the drawer to shake and unable to move smoothly in the direction of the cabinet. In addition, the slide rail will be damaged and cannot be used continuously, so the spring must be replaced to continue using the slide rail. In addition, when the drawer carries a small amount of articles, the load of the slide rail is too small, so that the spring tension is too much, causing the drawer to move quickly in the direction of the cabinet. In addition, the slide rail drives the drawer to directly impact the cabinet, causing noise and vibration, and causing damage to the cabinet and the drawer, so that they cannot be used continuously.

[0004] Furthermore, in order to change the load of the slide rail, the spring must be removed from the slide rail and another spring must be put into the slide rail.
