It should be noted that in this embodiment, the operating unit 5 is completely disposed between the first wall 21 and the second wall 22, but it is not limited to this. In other embodiments, the operating unit 5 It is also possible that only a part is disposed between the first wall 21 and the second wall 22, and another part, such as a part of the operating portion 511, is exposed instead of being located between the first wall 21 and the second wall 22.

11-13, the switch member 51 can be operated to pivot toward the frame 3 to be in a pressed state, for simultaneously releasing the engagement relationship between the operating portion 511 and the handle 4 and releasing the latching lever portion The engagement relationship between 512 and the first side arm 31. When the switch 51 pivots in the direction of the frame 3, the operating portion 511 does not engage the hook 41 of the handle 4, and the handle 4 can be opposed to The pivot end 42 pivots. In addition, when the switch member 51 is in a pressed state, the engaging section 512c leaves the engaging portion 313a without engaging the first side arm 31, and the necked section is linked 512b is located in the engaging portion 313a and aligned with the movable portion 313b. Since the width of the movable portion 313b is greater than the width of the necked section 512b, the necked section 512b can be located in and opposite to the movable portion 313b The movable portion 313b is moved, thereby enabling the second section 312 to move relative to the necked section 512b and extend from the base 2. Both ends of the elastic member 52 are respectively sleeved on the positioning protrusion 261 and the protrusion 511a, and when the switch member 51 is operated to pivot in the direction of the frame 3 At this time, the elastic member 52 will be compressed to apply an elastic restoring force to the switch member 51, so that the switch member 51 can return to the non-pivoted initial position. The engaging section 512c is engaged with the engaging portion 313a of the first side arm 31 to prevent the second section 312 of the first side arm 31 from moving in the slot 28. In other embodiments, the elastic member 52 may not be provided, but in this case, the user needs to manually restore the switch member 51 to the restoring position after operating the switch member 51. When the elastic member 52 is not set, it is also It is not necessary to provide the positioning protrusion 261 and the protrusion 511a for fixing the elastic member 52, and the abutting plate 26 for providing the positioning protrusion 261.

1, 2 and 8, the EMI shield 6 is approximately in an inverted U-shape to cover the first wall 21, the second wall 22 and the rear side 29 of the base 2 to prevent the hard disk 1 Subject to electromagnetic interference. The light guide posts 7 are arranged on the second side arm 32 and extend along one of the supporting plate portion 323 and the engaging portion 321 in the front-rear direction D1. The light guide posts 7 pass through the second wall 22 and The joint plate 324, and connected to the server system (not shown), can transmit the color change of the hard disk 1 light to prompt the user to confirm whether the hard disk tray and the hard disk 1 are installed and positioned, for example, if not installed When positioning, one of the light guide rods 7 will display a red light; if it has been installed and positioned, the other light guide rod 7 will display a green light, which means that the hard disk 1 can work normally, or the two light guide rods 7 can flash at different frequencies Ways to indicate the positioning or operating status of the hard disk 1 such as normal operation, failure, incorrect installation, etc. The number of light guide posts 7 is not limited to two. In other embodiments, only one can be provided, and the state of the hard disk 1 can be distinguished according to the state of the transmitted light.

Referring to FIG. 14, a second embodiment of a bracket for a hard disk 1 of the present invention is substantially the same as the first embodiment, except that the elastic member 52 of the second embodiment is a torsion spring sleeved on the pivot 514 , One end of the elastic member 52 abuts against the abutment plate 26, and the other end is fixedly clamped against one of the connecting wall portions 513. When the switch member 51 is operated to pivot toward the frame 3 by an external force, the elastic member 52 is interlockedly compressed to apply an elastic restoring force to the switch member 51, so that the switch member 51 can automatically return to the original position without pivoting when the switch member 51 is not subjected to external force.

To sum up, the hard disk tray of the present invention can be operated to pivot around the pivot 514 by the switch member 51 of the operating unit 5, so that the switch member 51 has both the switch member 51 and the handle 4 The function of the engagement relationship and the release of the engagement relationship between the switch 51 and the first side arm 31 of the frame 3, the first side arm 31 can move away from the base 2 so that the first side arm 31 and The distance of the second side arm 32 is increased to facilitate the removal of the hard disk 1. This design makes the operation more convenient for users, so it can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
