Abstract

A hard disk device includes a hard disk having two opposite first sides, a second side interconnecting the first sides, and two corner portions defined by the first and second sides, and a slide rail mechanism including two first plates to be disposed slidably in a housing, and a second plate. Each first plate has a first section connected to the second plate, and a second section connected to the first section. The first section is spaced apart from the respective first side and is provided with a first support element for abutting against the corresponding corner portion. The second section abuts against the corresponding first side and is provided with positioning pins for engaging positioning holes in the corresponding first side. The second plate is spaced apart from the second side and is provided with second support elements for abutting against the second side.

Claims

1. A hard disk device mountable removably in a housing, the housing having two opposite sides which are respectively provided with slide grooves, said hard disk device comprising:

a hard disk having two opposite first sides, a second side having two ends connected respectively to said first sides, and two corner portions cooperatively defined by said first sides and said second side, each of said first sides being formed with two positioning holes; and

a slide rail mechanism connected removably to said hard disk, and including two first plate members and a second plate member, said first plate members extending respectively from two ends of said second plate member in a same direction and in a spaced-apart relationship to be disposed slidably and respectively in the slide grooves, each of said first plate members having a first section connected to said second plate member, and a second section connected to a free end of said first section, said first section being spaced apart from a respective one of said first sides and being provided with a first support element for abutting against a respective one of said corner portions, said second section abutting against a respective one of said first sides and being provided with two positioning pins that are to be inserted respectively into said positioning holes, said second plate member being spaced apart from said second side and being provided with two second support elements for abutting against said second side.

2. The hard disk device of claim 1, wherein said first support element extends inclinedly toward said second plate member.

3. The hard disk device of claim 2, wherein said first support element is configured to be rounded at a portion where said first support element abuts against the respective one of said corner portions.

4. The hard disk device of claim 1, wherein said two second support elements extend inclinedly toward each other.

5. The hard disk device of claim 4, wherein each of said second support elements is configured to be rounded at a portion where the respective one of said second support elements abuts against said second side.

6. The hard disk device of claim 1, wherein said second section of each of said first plate members is formed with two engaging holes for extension of said positioning pins therethrough.

7. The hard disk device of claim 6, wherein each of said positioning pins has an engaging portion to be received fittingly in a respective one of said engaging holes, and an insert portion connected to said engaging portion and insertable into the respective one of said positioning holes.

8. The hard disk device of claim 1, wherein each of said first sides is formed with an auxiliary positioning hole, said second section of each of said first plate members being further provided with an auxiliary positioning element for insertion into said auxiliary positioning hole of a respective one of said first sides.

9. The hard disk device of claim 8, wherein said auxiliary positioning element has a forked free end.

10. The hard disk device of claim 1, wherein said two first plate members, said second plate member, said two first support elements, and said two second support elements are integrally formed and are made of a plastic material.

11. A slide rail mechanism connectible removably to a hard disk so as to permit the hard disk to be mounted removably in a housing, the housing having two opposite sides which are respectively provided with slide grooves, the hard disk having two opposite first sides, a second side having two ends connected respectively to the first sides, and two corner portions cooperatively defined by the first sides and the second side, each of the first sides being formed with two positioning holes, said slide rail mechanism comprising two first plate members and a second plate member, said first plate members extending respectively from two ends of said second plate member in a same direction and in a spaced-apart relationship to be disposed slidably and respectively in the slide grooves, each of said first plate members having a first section connected to said second plate member, and a second section connected to a free end of said first section, said first section being disposed to be spaced apart from a respective one of the first sides and being provided with a first support element for abutting against a respective one of the corner portions, said second section being disposed to abut against a respective one of the first sides and being provided with two positioning pins that are to be inserted respectively into the positioning holes, said second plate member being disposed to be spaced apart from the second side and being provided with two second support elements for abutting against the second side.

12. The slide rail mechanism of claim 11, wherein said first support element extends inclinedly toward said second plate member.

13. The slide rail mechanism of claim 12, wherein said first support element is configured to be rounded at a portion where said first support element is disposed to abut against the respective one of the corner portions.

14. The slide rail mechanism of claim 11, wherein said two second support elements extend inclinedly toward each other.

15. The slide rail mechanism of claim 14, wherein each of said second support elements is configured to be rounded at a portion where the respective one of said second support elements is disposed to abut against the second side.

16. The slide rail mechanism of claim 11, wherein said second section of each of said first plate members is formed with two engaging holes for extension of said positioning pins therethrough.

17. The slide rail mechanism of claim 16, wherein each of said positioning pins has an engaging portion to be received fittingly in a respective one of said engaging holes, and an insert portion connected to said engaging portion and insertable into the respective one of the positioning holes.

18. The slide rail mechanism of claim 11, each of the first sides being formed with an auxiliary positioning hole, wherein said second section of each of said first plate members is further provided with an auxiliary positioning element for insertion into the auxiliary positioning hole of a respective one of the first sides.

19. The slide rail mechanism of claim 18, wherein said auxiliary positioning element has a forked free end.

20. The slide rail mechanism of claim 11, wherein said two first plate members, said second plate member, said two first support elements, and said two second support elements are integrally formed and are made of a plastic material.
