Then, the two protrusions 342 on the partition plate 34 of the mounting frame 30 are correspondingly inserted into the opening 252 of the front plate 25 while aligning the positioning holes 251 and the partition plate 34 on the front plate 25. The positioning groove 341 and the screw 80 lock the positioning hole 251 and the positioning groove 341 together, so that the mounting bracket 30 is fixed to the front plate 23 of the receiving frame 20.

The pivot hole 413 on the handle 41 is sleeved on the fixing post 331 on the top wall 33 of the mounting bracket 30, so that the handle 41 is rotatably fixed to the mounting bracket 30. One end of an elastic member 90 is sleeved on the sleeve 414 of the handle 41, and the other end is received in the pressing groove 351 of the connecting plate 35, thereby mounting the elastic member 90 to the handle 41. Between the mounting frame 30 and the mounting frame 30. The locking block 423 of the sliding member 42 is slidably snapped into the two smaller fastening holes 3611 of the positioning portion 36. The sleeve 4211 on the protrusion 421 passes through the positioning portion. The larger buttonhole 3612 of 36, the slider 42 is thus slidably mounted to the mounting bracket 30. One end of the other elastic member 100 is sleeved on the sleeve 4211, and the other end is sleeved on the sleeve 321 of the side wall 32, so as to be mounted on the sliding member 42 and the side wall 32 of the mounting bracket 30. between.

Referring to FIG. 5 together, before the assembled receiving frame 20 is loaded into the casing 10, the handle 41 is in an unlocked position, at which time the handle 41 is disengaged from the sliding member 42 and is rotated outward. The elastic member 90 is no longer elastically deformed, so that the card bump 412 no longer blocks the mounting bracket 30 from being inserted between the partitions 11 of the casing 10, and the sliding member 42 is located away from the side wall 42. In a first position, the resilient member 100 has an initial length.

In use, the receiving frame 20 is inserted between the two partitions 11 of the casing 10, and the handle 41 is rotated inwardly in the direction of the mounting bracket 30, so that the handle 41 is The card bump 412 gradually snaps into the engaging groove 112 of the casing 10, and the elastic member 90 is elastically deformed by being pressed by the handle 41. When the inclined surface of the latching portion 415 of the handle 41 abuts against the edge of the slider 42 side, the handle 41 is continuously pressed, and the inclined surface of the latching portion 415 presses the slider 42 The sliding member 42 is slid in a first direction away from the one of the latching portions 415, and the protrusion 421 and the latching block 423 are respectively slid in the corresponding button holes 3611 and 3612. 100 is elastically deformed by being pressed by the protrusion 421 of the sliding member 42. When the sliding member 42 is located closest to the side wall 32, the elastic member 100 has a maximum elastic deformation amount and a minimum length. The inclined surface of the locking portion 415 can pass over the sliding member 42. At this time, since the locking portion 415 no longer presses the sliding member 42, the elastic member 100 elastically recovers until The minimum length is restored to the original length, and thus the slider 42 is forced to slide to a first position in a second position in a second direction opposite the first direction, thereby causing the slider 42 to engage the card The buckle portion 415 is snap-fitted to prevent the handle 41 from rotating in the reverse direction. At this time, the elastic member 90 has a maximum elastic deformation amount and a minimum length, and the card bump 412 of the handle 41 is buckled in the engaging groove 112 of the casing 10, and the blocking piece 114 The housing 20 is snapped into the card slot 511 to be mounted in the housing 10.

When disassembling, the sliding member 42 is driven to slide from the first position to the second position in the second direction by the recess 422, and the elastic member 100 is received by the protrusion 421 of the sliding member 42. Squeeze and elastically deform. When the edge of the slider 42 is disengaged from the latching portion 415 of the handle 41, the elastic member 90 is elastically restored, and thus the handle 41 is forced to rotate axially with the fixing post 331 of the mounting bracket 30. When the card bump 412 rotates out of the engaging groove 112 and the blocking piece 114 is disengaged from the card slot 511, the receiving frame 20 can be detached from the casing 10. at this time, Release of the slider 42, the resilient return of the resilient member 100 forces the slider 42 to slide from the second position to the first position in the first direction.

In the present embodiment, the elastic members 90, 100 are each a compression spring. When the storage rack 20 needs to be installed with a hard disk drive, a screw 70 passes through the fixing hole 51 of the shockproof pad 50 and the mounting hole 2313 of the fastening tongue 231, and then the hard disk drive (not shown) A positioning hole (not shown) on the display unit affixes the receiving frame 20 to the hard disk drive. At this time, one side of the shock pad 50 is in close contact with the hard disk drive. When the hard disk is viable to generate vibration, since the shock pad 50 is made of a soft elastic material, the shock pad 50 can absorb the vibration generated by the hard disk drive, thereby improving the hard disk drive reading. Correctness and reduce the noise generated by the vibration of the hard disk drive. The elastic pieces 61, 62 can be used to prevent electromagnetic waves in the casing 10 from radiating outward, and are manufactured using standard parts, which reduces production costs.
