ABSTRACT:
A wheel type drawer pulling force adjusting apparatus is installed to a slide module having a bottom rail, a middle rail and an internal rail. A latch member is fixed to the bottom rail. The slidable middle rail is embedded onto the bottom rail. The internal rail is embedded and slidable on the middle rail. A limit member and a turning wheel are embedded on the internal rail and the bottom rail opposite to the latch member. Positioning slots of different sizes are on the turning wheel. The internal rail is connected with a drawer. During installation, the size of the positioning slots of the turning wheel latched by the limit member determines the level of retracting the limit member, and the tightness of the limit member latched to the latch member of the bottom rail is adjusted to allow users to apply an appropriate force to open the drawer.
