Abstract: A drawer slide with a two-way opening and closing structure includes: a main rail, a pivot block pivotally provided on the main rail, a slide rail slidably mounted on the main rail, and a pull lever pivotally disposed on the slide rail. The main rail has a limiting portion disposed along a vertical direction. The pivot block has an offset post movably disposed at the limiting portion along the vertical direction, and a first dislocation block which can be locked with a second dislocation block of the pull lever in a staggered manner. The user can set two sets of identical drawer slides with the two-way opening and closing structure on two sides of the drawer, and the first and second dislocation blocks can be misaligned by the limiting portion, namely, two identical slide rails 40 can be applied to the two opposite sides of the drawer.

Abstract: A track structure for a slideway includes a track body which has a main wall and two lateral walls integrally formed at two sides of the main wall. The track body is formed by folding two sides of a metal plate with a thickness t0 and subjected to shaping process, including hot rolling, cold rolling, hot drawing, cold drawing, or hot and cold forging, to make the main wall has a shrinkage c1, the two lateral walls have a shrinkage c2, c1 and c2 are between ? and ?, the main wall has a thickness t1, the lateral walls have a thickness t2, and t1=(1?c1)t0, t2=(1?c2)t0, the track body has a shaping section with a length L at each of the folded portions of the track body, and t0<L<(t12+t22)1/2.

Abstract: A locking/unlocking apparatus for a drawer is applicable to be assembled on a fixed slide rail and a slidable slide rail of a drawer or on a drawer body and a drawer cabinet. The locking/unlocking apparatus comprises a drive element disposed on the slidable slide rail or the drawer body, a main body fixed on the fixed slide rail or the drawer cabinet, a slide block slidably disposed on the main body, and a spring disposed between the main body and the slide block. By such arrangements, when the drawer is pulled by a large force, it can prevent the slide rails, the drawer body or the locking/unlocking apparatus from being damaged.

Abstract: A return device for a drawer employs an actuator to drive a slide block, when the drawer is pulled open, the slide block is moved into a positioning concave and positioned therein while stretching an elastic member. Or pushing the drawer back can make the slide block slide out of the positioning concave, meanwhile, the elastic member pulls the drawer back to its original position. Furthermore, since the angle between the slide surface of the positioning concave of the positioning member and the track is obtuse, it is easy for the slide block to slide in and out, so that the drawer can be easily positioned and unlocked from the positioned state.

Abstract: An interlocking device for a drawer slide is provided with an outer board, a fixed seat, two linkage members, a middle board, a restricting member and an inner board. When one of the drawers in a cabinet is pulled toward the first end of the outer board, the inner board will be moved together with the drawer and push the restricting member, the middle board and the actuating block, then the two linkage members are pushed to move in an opposite direction to the Y direction, the two connecting rod are caused to push the linkage members of other interlocking devices, so that the inclined surface of the guiding portion of one of the linkage members of other interlocking devices will be received in the receiving space and abutted against the inclined guiding surface of the actuating block of the middle board to prevent other drawers from being pulled out.

Abstract: A hidden self-closing drawer slide assembly comprises a base, a pressure cylinder, a traction member and a spring. The traction member is movably received in the base. The traction member is provided with a guiding block. The base is formed with a slide groove, and one end of the slide groove is folded into a positioning portion. The guiding block guides the traction member to linearly moves in the slide groove, and slides through the slide groove and finally into the positioning portion, and the locking protrusion of the traction member will disengage from the concave locking portion of the pressure cylinder. The traction member will be pushed back by the spring to its original position, and the pressure cylinder provides a buffering effect to absorb the shock.

Abstract: An automatic locking/unlocking apparatus for a drawer is applicable to be assembled on a fixed slide rail and a slidable slide rail of a drawer or on a drawer body and a drawer cabinet. The automatic locking/unlocking apparatus comprises a drive element disposed on the slidable slide rail or the drawer body, a main body fixed on the fixed slide rail or the drawer cabinet, a slide block slidably disposed on the main body, and a spring disposed between the main body and the slide block.

Abstract: An interlocking device for a drawer slide is disposed at the end of a drawer and comprises a positioning block disposed at the end of the fixed slide rail, at least one moveable slide rail received in the fixed slide rail, a control block assembly, a first locking member, a second locking member, a pivot control member and a spring. The first and second locking members are pushed to clamp the pivot control member by the spring. The control block of the control block assembly is fixed at the end of the moveable slide rail. The drawer is used to move a control block on the slide rail, and then the guiding portion and the pushing block of the control block can push the pivot control member to move. Therefore, the interlocking device for a drawer slide is simple.
