Detailed ways:

The utility model is described in detail below in conjunction with accompanying drawing and specific embodiment:

Referring to FIG. 1 to FIG. 5 are specific structural views of an embodiment of a dual-layer disk drive of the present invention. It can be seen from the figure that the utility model includes a support frame 10 , a locking member 30 , a pull rod 20 and a reset component 40 .

Wherein, the support frame 10 is made of thin plate metal parts, and two slide grooves 11 are respectively arranged on the two side plates of the support frame 10. The limit flanges 11c are connected and combined to form, the bottom cover groove 11a is located at the front end of the chute 11, the limit flange 11c is located at the tail end of the chute 11, and the strip slot 11b is connected to the back cover groove 11a and the limit protrusion. Between edge 11c.

Both sides of the disk drive 50 are respectively provided with two locking positions. The locking positions in this embodiment are flat-head screw heads 51. The two flat-head screw heads 51 are nested in the chute 11 and cooperate with the chute 11 in a slidable gap. .

The locking member 30 is used to lock the two disk drives 50 in the supporting frame 10 . To achieve this purpose, the utility model fixes the locking member 30 on the middle part of the right side of the supporting frame. Locking piece 30 comprises a square locking piece body 31, is positioned at the two ends of locking piece body 31 left and right side walls and is respectively provided with a fixing ear 32, and the middle part of locking piece body 31 front sidewalls is provided with a limit block 33; The ears 32 are correspondingly inserted into the L-shaped hooks 14 located on the right side of the support frame 10, and the stop block 33 is inserted into the position-limiting hole 15 correspondingly located on the right side of the support frame 10, so that Effectively fix the locking piece 30 on the right side of the support frame 10 . In addition, a slender elastic arm 34 extends from both ends of the rear side wall of the locking member body 31. The extending direction of the two elastic arms 34 is slightly bent towards the support frame 10 and sinks into the elongated slot 11b of the chute 11. The extended tails of the two elastic arms 34 are connected by a cross bar 35, and the cross bar 35 is provided with a guiding inclined surface 35a (refer to FIG. 6 ) which forms an angle with the side of the support frame 10 .

When the disk drive 50 is loaded into the support frame 10, the tail end of the elastic arm 34 pushes the screw head 51 positioned at the rear part of the side of the drive 50, so that the disk drive 50 cannot freely slide out from the support frame 10, thereby effectively moving the disk drive. The driver 50 is fixed in the supporting frame 10 .

The pull rod 20 is used to remove the disk drive 50, which is also located on the right side of the support frame 10, between the support frame 10 and the locking member 30, and is connected to the support frame 10 through a sliding mechanism and can be close to the support frame 10 swipe to the right of the . The sliding mechanism includes two limiting columns 12 and two thin slots 21 , and the two limiting columns 12 are respectively nested in the two thin slots 21 . Two spacer posts 12 are contained in the two I-shaped structures formed on the right side of the support frame by two screws, and two thin slotted holes 21 are respectively located at the front and rear parts of the pull rod.

The front end of the pull rod 20 is provided with a protruding handle 25 perpendicular to its sliding direction, and the tail is provided with two first push blocks 22 and two second push blocks 23 . The second push block 23 is used to push the screw head 51 on the disk drive 50. The second push block 23 is respectively a protrusion on the left and right side walls of the pull rod 20, and the second push block 23 is connected to the magnetic disk. The place where the screw head 51 contacts on the driver 50 is an arc surface; the first push block 22 is used to push away the elastic arm 34 on the lock member 30, and the first push block 22 is two parallel protrusions on the front side of the pull rod 20 , and the upper surface of the first push block 22 is composed of a push slope 22a at an angle to the right side of the support frame 10 and a slideway plane 22b parallel to the surface of the pull rod; wherein, the push slope 22a tops Lean on the guide slope 35a on the aforementioned cross bar 35.

The reset part 40 is used to pull the pull rod 20 back to the initial position. The reset part 40 of this embodiment is a tension spring. On the circular hole 13 on the right side.

Both the locking member 30 and the pull rod 20 of the practical example are made of plastic.

The concrete loading and unloading principle and process of the disk drive of the present utility model are described in detail below:

When the disk drive 50 is installed, align the screw head 51 on the side of the disk drive 50 with the bottom cover groove 11a of the chute on the support frame 10 (refer to FIG. 2 ), and further push the disk drive 50 in, the screw head 51 When pushed to the tail end of the chute 11, the screw head 51 pushes the elastic arm 34 on the locking member 30 to bend outwards, and the screw head 51 slides over the elastic arm 34 and leans against the limiting flange at the tail end of the chute 11 11c can no longer slide inward. At this time, the elastic arm 34 immediately rebounds and pushes against the screw head 51, so that the disk drive 50 cannot slide outward in the return stroke. In this way, the purpose of locking the disk drive 50 in the supporting frame 10 is achieved (refer to FIG. 3 ). At this time, the pushing slope 22a on the pull rod 20 just leans against the guide slope 35a on the locking member 30, and the second pushing block 23 on the pull rod 20 is a short distance away from the screw head 51 on the disk drive 50 , the limit column 12 on the support frame 10 is located at the front end of the thin strip slot hole 21 on the pull rod 20 (refer to FIG. 6 ).

When dismounting the disk drive 50, hold the handle 25 at the front end of the pull rod 20 and pull the pull rod 20 outwards, the first push block 22 and the second push block 23 of the pull rod move outward together with the pull rod 20, and the first push block The pushing inclined surface 22a on the locking member 22 pushes and slides over the guiding inclined surface 35a on the locking member 30, so that the elastic arm 34 on the locking member 30 bends and deforms outward, and the first pushing block 22 moves outward further, and the first pushing block 22 moves outward. When the slideway plane 22b on the push block 22 slides to the position of the guide slope 35a, the degree of outward bending of the elastic arm 34 reaches the maximum, and simultaneously the pushing action of the elastic arm 34 on the screw head 51 on the disk drive 50 is released. This allows the disk drive 50 to slide freely outward. Then, the second push block 23 on the pull rod 20 slides to the position of the disk drive 50 (refer to FIG. 7 ), and with the further outward movement of the pull rod 20, pushes the disk drive 50 and slides out until the pull rod 20 The tail end of the thin strip slot 21 slides to the position of the limit rod 12, and the pull rod 20 slides outward to its maximum sliding distance. At the same time, the disk drive 50 also slides to the position where it can be taken out gently by hand, reaching the position of the disk drive. 50 for dismantling purposes.

At last the hand releases the handle 25 on the pull bar 20, and the pulling force of the reset part 40 tension spring pulls the pull bar 20 back to its initial position automatically. Complete the whole process of the whole extractable loading and unloading of the utility model like this.

In summary, the key point of this utility model is that on the one hand, the deformable elastic arm on the locking piece is used to effectively push the disk drive, so as to achieve the purpose of locking the disk drive; on the other hand, a slidable And reset the pull bar to release the restriction of the elastic arm to the disk drive and automatically take out the disk drive, and finally realize the effect of the pull-out disassembly of the disk drive.

The above is only a preferred embodiment of the extractable fixed structure of a disk drive of the present utility model, and does not limit the technical scope of the present utility model. Any minor modifications, equivalent changes and modifications still belong to the scope of the technical solutions of the present utility model.
