Abstract

A lock-controlled drawer slide structure comprises a lock device, a steel rope, and a latch device, wherein the lock-controlled drawer slide is connected with an interlocking device so as to lock several drawers securely. The lock device comprises a fixing main body, a lock head, a rotatory means, a pull plate, and a fixing plate. The steel rope comprises two fixing heads. The latch device comprises a base, a slidable means, a braking means, a fastening plate, and a cover. The steel rope is utilized to connect the lock device with the latch device securely without the use of complicated fixing structure. The drawers can be locked together by using the braking means that controls the interlocking device. When the braking device is released from being braked by the interlocking device, the braking device retrieves its ability to lock or unlock the upper or lower drawers.

Claims

1. A lock-controlled drawer slide structure connected with an interlocking device for locking or unlocking a plurality of drawers, the lock-controlled drawer slide structure comprising:

a lock device comprising a fixing main body, a lock head, a rotatory means, a pull plate, and a fixing plate, wherein the lock head is mounted on the outside of the fixing main body for rotating the rotatory means, a pillar is bias mounted on an operation plate of the rotatory means, a hooking hole is extendedly formed on one side of the pull plate for being hooked by one end of the steel rope, a long opening is formed on the pull plate, and the pillar of the rotatory means is located to penetrate through an open-ended trench;

a steel rope comprising two fixing heads; and

a latch device comprising a base, a slidable means, a braking means, a fastening plate, and a cover, wherein an action chamber is formed in the base for holding the slidable means, two axial pillars are transversely mounted in one side of the action chamber for holding two elastic devices, two guide channels constituted by two opposite lateral rails are symmetrically formed on upper and lower portions of the other side of the action chamber, a slide trench is formed on one side of the slidable means for holding one of the fixing heads of the steel rope, two stair-shaped trenches are symmetrically formed on the other side of the slidable means for holding a top block of the braking means, a middle neck portion of the braking means is movably embedded in one of the guide channels, a reverse U-shaped crotched rod is located on a lower portion of the braking means, the fastening plate is mounted on the outside of the base for fixing the latch device on a slide, and a first hooking sheet and two second hooking sheets are mounted on both sides of the fastening plate, respectively, wherein the first hooking sheet is designed to hook the guide channel and the second hooking sheets are designed to hook a lateral trench of the slide for securely coupling the latch device with the slide.

2. The lock-controlled drawer slide structure of claim 1, wherein the rotatory means has a diameter dimension different from that of the operation plate.
