detailed description

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

1 to 7, in this embodiment, the carrier tray 100 is preferably a metal rectangular drawer and the carrier tray 100 is provided with at least one perforation 101, and the carrier tray 100 is arranged in the cabinet 10 or the frame 10 For accommodating server hosts or hard disks.

Referring to FIG. 2 and FIG. 4 to FIG. 7 , the handle assembly 200 is disposed on the tray 100 for the operator to hold to facilitate pulling the tray 100 out of the cabinet 10 or the rack 10 for maintenance. In this embodiment, the handle assembly 200 preferably includes a fixing seat 210 , a handle 220 and a sliding block 230 . The fixing seat 210 is fixedly disposed on the outer wall of the tray 100 , and a sliding slot 211 is formed in the fixing seat 210 and at least one through slot 212 communicating with the sliding slot 211 is defined in the fixing seat 210 . The handle 220 is connected with the sliding block 230 , and the sliding block 230 is accommodated in the sliding slot 211 and can move along the sliding slot 211 , so that the sliding block 230 is movably connected to the fixing base 210 . The sliding block 230 is provided with at least one sliding tenon 231 corresponding to the through groove 212 , and the sliding tenon 231 is disposed in the corresponding through groove 212 and can move along the through groove 212 . In addition, the sliding block 230 is formed with a pushing slope 232 . The handle 220 is located outside the fixing seat 210 .

The locking elastic arm 300 is attached to the inner wall of the carrier plate 100, one end of the locking elastic arm 300 is fixed to the carrier plate 100, and the other end of the locking elastic arm 300 is provided with a stopper 310, and an actuation slope 311 is formed on the stopper 310. The actuating slope 311 is disposed obliquely relative to the locking elastic arm 300 . The blocking block 310 is accommodated in the sliding slot 211 so that the actuating slope 311 is located in the sliding slot 211 and fits against the pushing slope 232 of the sliding block 230 . At least one hook 320 protrudes laterally from a middle section of the locking elastic arm 300 corresponding to the through hole 101 on the carrier plate 100 , and the hook 320 protrudes from the outer wall of the carrier plate 100 through the corresponding hole 101 . The hook 320 snaps into the cabinet 10 , the rack 10 or the slide rail connecting the tray 100 with the cabinet 10 or the rack 10 , and locks the tray 100 in the cabinet 10 or the rack 10 .

At the same time, the hook 320 snaps into the cabinet 10 or the rack 10 or the slide rail connecting the tray 100 and the cabinet 10 or the rack 10 to lock the tray 100 in the cabinet 10 or the rack 10 .

Referring to FIG. 10 , the operator can also directly hold the handle 220 to push the tray 100 back into the cabinet 10 or the rack 10 . When the operator pushes the handle 220 into the cabinet 10 or the frame 10, the slider 230 breaks away from the stopper 310, and the stopper 310 can be pushed back into the chute 211 by the restoring force of the locking elastic arm 300, and simultaneously locks The hook 320 protrudes from the tray 100 . When the operator continues to push the tray 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 tray 100 by the cabinet 10 or the rack 10, When the hook 320 moves to the corresponding clamping position on the cabinet 10 or the rack 10, the locking elastic arm 300 springs back, and the hook 320 snaps into the cabinet 10, the rack 10 or connects the tray 100 to the rack 10 or the rack. The slide rails of the rack 10 lock the tray 100 in the cabinet 10 and the rack 10.

The operator only needs to hold the handle and directly pull out the tray 100, and at the same time, the tray 100 can be unlocked and released by the self-unlocking mechanism of the cabinet drawer of the present utility model. Therefore, compared with the prior art, the cabinet drawer self-unlocking mechanism of the present invention makes the tray 100 easier to operate.
