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) a lock device having;

i) a fixing main body;

ii) a rotatory device having an operation plate and a pillar connected to the operation plate;

iii) a lock head mounted on an outside of the fixing main body and controlling a rotation of the rotatory device;

iv) a pull plate having a hooking hole, an opening, and an open-ended trench, the pillar of the rotatory device is inserted through the open-ended trench; and

v) a fixing plate;

b) a steel rope comprising two fixing heads, a first fixing head of the two fixing heads is connected to the hooking hole of the pull plate; and

c) a latch device having;

i) a slidable device having a slide trench formed on a first side thereof and two stair-shaped trenches symmetrically formed on a second side thereof, the slide trench holding a second fixing head of the two fixing heads of the steel rope;

ii) a base having an action chamber, the slidable device is slidably located in the action chamber, two axial pillars are transversely mounted in a first side of the action chamber, two guide channels constituted by two opposite lateral rails are symmetrically formed on upper and lower portions of a second side of the action chamber;

iii) two elastic devices, one of the two elastic devices is located on each of the two axial pillars;

iv) a braking device having a top block, a middle neck portion, and a reverse U-shaped crotched rod, the top block is inserted into one of the two stair-shaped trenches, the middle neck portion is movably embedded in one of the guide channels, the reverse U-shaped crotched rod is located on a lower portion of the braking device;

v) a fastening plate mounted on an outside of the base and fixing the latch device on a slide, the fastening plate having a first hooking sheet and two second hooking sheets are mounted on opposing sides of the fastening plate, the first hooking sheet is hooked to one of the guide channels and the second hooking sheets are adapted to be hooked to a lateral trench of the slide securely coupling the latch device with the slide; and

vi) a cover connected to the base.

2. The lock-controlled drawer slide structure according to claim 1, wherein a main body of the rotatory device has a diameter different from a diameter of the operation plate of the rotatory device.
