Cabinet drawer self-unlocking mechanism

The invention relates to a cabinet drawer, in particular to a cabinet drawer self-unlocking mechanism.

Most of the existing servers are installed in the drawers of the cabinet or the rack, and the drawers can be pulled out for maintenance during maintenance. In order to prevent the drawer from sliding out of the cabinet or the rack, a locking mechanism is generally provided between the drawer and the cabinet or the rack to lock the drawer in the cabinet or the rack. When performing maintenance, the operator needs to unlock the locking mechanism before pulling the drawer out of the cabinet or the rack. The drawer is quite cumbersome after loading the hard disk. The operator needs to pull the handle on the drawer with both hands to pull out the drawer. It is quite inconvenient to operate the locking mechanism when pulling the drawer.

In view of the above, the inventors of the present invention have made great efforts to solve the above problems in view of the above-mentioned prior art, and have made great efforts to solve the above problems, which has become the object of improvement of the present inventors.

The invention provides a cabinet drawer self-unlocking mechanism capable of simultaneously unlocking a drawer when the drawer is pulled out from the cabinet.

The invention provides a cabinet drawer self-unlocking mechanism, which comprises a carrier tray, a grip assembly and a locking elastic arm. The grip assembly comprises a fixing seat, a grip and a slider connecting the grip, the fixing seat is fixedly disposed on the carrier, and the slider is movably connected to the fixing seat. The locking elastic arm is attached to the loading tray, and one end of the locking elastic arm is fixed to the loading tray, the locking elastic arm is formed with a matching moving slope and the actuating inclined surface is inclined with respect to the locking elastic arm, and the locking elastic arm is laterally protruded to form a hook And the hook protrudes from the outer wall of the carrier. The slider is configured to move against the actuating ramp to bend the locking arm to retract the hook into the carrier.

In the self-unlocking mechanism of the cabinet drawer of the present invention, the fixing seat is formed with a sliding slot, and the sliding block is accommodated in the sliding slot and can move along the sliding slot. The actuating ramp is received in the chute. The other end of the locking elastic arm is provided with a stopper, the actuating slope is formed on the stopper, and the stopper is accommodated in the sliding groove. The slider is configured to move against the actuating ramp to push the stop out of the chute. The slider is formed with a pushing inclined surface, and the inclined inclined surface is attached to the actuating inclined surface. When the slider moves to push the bevel away from the actuation ramp, the slider secures the stop outside the chute.

In the self-unlocking mechanism of the cabinet drawer of the present invention, a fixing slot is defined in the fixing seat, and a slider is protruded from the slider, and the sliding jaw is disposed in the through slot and can move along the through slot. The locking elastic arm is attached to the inner wall of the carrier, the carrier has a through hole and the hook protrudes through the perforation to protrude the outer wall of the carrier. The fixing seat is disposed on the outer wall of the carrier.

Referring to FIG. 1, a preferred embodiment of the present invention provides a cabinet drawer self-unlocking mechanism including a carrier 100, a grip 220 assembly 200, and a locking elastic arm 300.

Referring to FIG. 1 to FIG. 7 , in the embodiment, the carrier 100 is preferably a metal rectangular drawer and the carrier 100 is provided with at least one through hole 101 , and the carrier 100 is disposed in the cabinet 10 or the frame 10 . Used to accommodate the server host or hard drive.

Referring to Figures 2 and 4 to 7, the grip assembly 200 is disposed on the carrier 100 for the operator to hold to facilitate pulling the carrier 100 out of the cabinet 10 or the frame 10 for maintenance work. In the present embodiment, the grip assembly 200 preferably includes a fixing base 210, a grip 220 and a slider 230. The fixing base 210 is fixedly disposed on the outer wall of the loading tray 100. A sliding slot 211 is defined in the fixing base 210, and the fixing base 210 defines at least one through slot 212 connecting the sliding slot 211. The grip 220 is coupled to the slider 230, and the slider 230 is received in the chute 211 and is movable along the chute 211, thereby causing the slider 230 to be movably coupled to the mount 210. The slider 230 protrudes from the through slot 212 with at least one slider 231. The slider 231 is disposed in the corresponding slot 212 and can move along the slot 212. Further, the slider 230 is formed with a pushing slope 232. The grip 220 is located outside of the holder 210.

The locking elastic arm 300 is attached to the inner wall of the loading tray 100. One end of the locking elastic arm 300 is fixed to the loading tray 100. The other end of the locking elastic arm 300 is provided with a stopper 310. The blocking block 310 is formed with a matching movable slope 311. And the actuating ramp 311 is disposed obliquely with respect to the locking arm 300. The stopper 310 is received in the sliding slot 211 such that the actuating ramp 311 is located in the sliding slot 211 and is in contact with the pushing inclined surface 232 of the slider 230. The middle portion of the locking elastic arm 300 corresponds to the through hole 101 on the carrier 100 and laterally protruded to form at least one hook 320, and the hook 320 protrudes through the corresponding through hole 101 to protrude the outer wall of the carrier 100. The hook 320 is inserted into the cabinet 10, the rack 10 or the slide rail connecting the carrier 100 and the cabinet 10 or the rack 10 to lock the carrier 100 within the cabinet 10 and the rack 10.

Referring to FIGS. 8 and 9, when the grip 220 is pulled by the operator, the slider 230 can move against the actuating ramp 311 to push the stopper 310 out of the chute 211, and bend the locking arm 300 to retract the hook 320. The carrier 100 is released from the cabinet 10 or the chassis 10 into the carrier 100. Moreover, when the slider 230 is moved to the pushing inclined surface 232 to be separated from the actuating slope 311, the slider 230 fixes the stopper 310 outside the sliding groove 211, thereby fixing the hook 320 in the carrier 100. Therefore, the operator can continue to pull the grip 220 to pull the carrier 100 out of the cabinet 10 or the rack 10.

After the operator pushes the carrier 100 back into the cabinet 10 or the frame 10, the handle 220 is pushed into the cabinet 10 or the frame 10 to disengage the slider 230 from the stopper 310, and the stopper 310 can be locked. The return spring force of the arm 300 is pushed back into the chute 211. At the same time, the hook 320 is inserted into the cabinet 10, the rack 10 or the slide rail connecting the carrier 100 and the cabinet 10 or the rack 10 to lock the carrier 100 within the cabinet 10 and the rack 10.

Referring to Figure 10, the operator can also directly grip the handle 220 to push the carrier 100 back into the cabinet 10 or the frame 10. When the operator pushes the grip 220 into the cabinet 10 or the frame 10, the slider 230 is disengaged from the stopper 310, and the stopper 310 can be pushed back into the sliding slot 211 by the return elastic force of the locking elastic arm 300. The hook 320 protrudes from the carrier 100. When the operator continues to push the carrier 100 into the cabinet 10 or the rack 10 until the hook 320 touches the cabinet 10 or the rack 10, the hook 320 is pressed into the carrier 100 by the cabinet 10 or the frame 10, When the hook 320 is moved to the corresponding latching position on the cabinet 10 or the rack 10, the locking arm 300 rebounds, and the hook 320 is inserted into the cabinet 10, the rack 10, or the connecting tray 100 and the cabinet 10 or the machine. The slide rail of the frame 10 locks the carrier 100 within the cabinet 10 and the frame 10.

The operator only needs to hold the grip to directly pull the carrier 100 outward, that is, the carrier 100 can be unlocked and released by the cabinet drawer self-unlocking mechanism of the present invention. Therefore, the cabinet drawer self-unlocking mechanism of the present invention makes the carrier 100 easier to handle than the prior art.

The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the invention, and other equivalent variations of the patent spirit of the present invention are all within the scope of the invention.
