Abstract: A push-open type slide structure comprises a top fastener and a locking device between an outer slide rail and a pull rod. The loading plate is extended from one side of the center portion of the main body. Two pillars are extended from both sides of the main body. A positioning fastener is coupled with the loading plate. A hook is mounted on the inner edge of the loading plate. A guide pillar is mounted on the rear end of the loading plate. The hook is inserted into the action trench of the main body and coupled with the elastic device. The locking device has a connection part for coupling with a guide part and a shaft holder. The push-open type slide structure is lockable or unlockable by pivotal rotation between the loading plate and the locking device. As a result, the push-open type slide structure can be controlled easily.

Abstract: An auto-locking structure used in a sliding track assembly for drawer is constructed to include a track located on the rear side of the outer sliding rail of the sliding track assembly, a sliding locking block sliding in the track and adapted to alternatively lock the inner sliding rail between the extended and received positions, and a tensile spring connected between the track and sliding locking block, the sliding locking block having a side locating hole defined between a sloping wall and a stop wall and an opening adjacent to the side locating hole for positively secure the inner sliding rail in the extended or received position.

Abstract: A sliding track assembly includes an outer rail, an intermediate rail, an inner rail, a stop member, a first sliding bearing, a second sliding bearing, and a locating plate, wherein the inner rail has a raised portion adapted to engage the stop member for enabling the intermediate rail to be moved with the inner rail outwards when pulling a drawer out of a desk; the stop member has a supporting rib bridging a sliding slot of the intermediate rail to support the stop member on the intermediate rail in position when the stop member engages a retaining block of the outer rail; the intermediate rail has two retaining flanges abutting two sides of a curved positioning portion of the spring to hold the spring in place.
