Abstract

A fixing device of a slide assembly has a bracket. The fixing device includes an insertion member, an engaging member and a resilient member. The insertion member is connected to the bracket and has a slot. The engaging member is slidably connected relative to the bracket and has an operation portion and an arm which extends through the slot of the insertion member. The arm has a first protrusion. The resilient member provides a force to the engaging member to extend the first protrusion beyond the slot of the insertion member. By moving the operation portion, the first protrusion is controlled to be retracted toward the slot of the insertion member.

Claims

1. A slide assembly comprising:

a support member and a bracket connected to the support member, the bracket having a side wall and an end wall, the side wall having a window, the end wall substantially perpendicularly connected to the side wall;

at least one installation member connected to the end wall of the bracket;

an insertion member connected to the end wall of the bracket and having a slot defined therein;

an engaging member slidably connected relative to the bracket and having an operation portion and an arm, the operation portion located corresponding to the window of the side wall of the bracket, the arm extending through the slot of the insertion member and having a first protrusion; and

a resilient member providing a force to the engaging member to extend the first protrusion beyond the slot of the insertion member.

2. The slide assembly as claimed in claim 1, wherein the end wall has a through hole and the insertion member extends through the through hole.

3. The slide assembly as claimed in claim 2, wherein the insertion member has a body and a head connected with the body, the body of the insertion member has a recessed area and a first locking portion which is located in the recessed area and adjacent to the head.

4. The slide assembly as claimed in claim 1, wherein the end wall has two installation holes, a fixing member and two installation members are connected to the fixing member, the fixing member is fixed to the bracket, and the installation members extend through the installation holes of the end wall of the bracket respectively.

5. The slide assembly as claimed in claim 4, wherein each installation member has a movable rectangular portion, a cylindrical portion and a spring, the rectangular portion is slidably connected relative to the cylindrical portion, the spring applies a force to the rectangular portion so that the rectangular portion extends beyond the fixing member and located at a pre-set position.

6. The slide assembly as claimed in claim 5, wherein the operation portion of the engaging member slidably contacts an inside of the window, so that the engaging member is movable relative to the insertion member to control the first protrusion of the arm to protrude beyond or to retract toward the slot of the insertion member.

7. The slide assembly as claimed in claim 6, wherein the side wall of the bracket has a first guide portion, the engaging member has a second guide portion, a guide member is located between the first and second guide portions.

8. A fixing device comprising:

a bracket;

at least one installation member connected to the bracket;

an insertion member connected to the bracket and having a slot;

an engaging member slidably connected relative to the bracket and having an arm which extends through the slot of the insertion member, the arm having a first protrusion; and

a resilient member providing a force to the engaging member to extend the first protrusion beyond the slot of the insertion member.

9. The fixing device as claimed in claim 8, wherein the bracket having a side wall and an end wall, the end wall is substantially perpendicularly connected to the side wall, the engaging member has an operation portion which is located corresponding to the side wall of the bracket.

10. The fixing device as claimed in claim 9, wherein the end wall has a through hole, and the insertion member extends through the through hole.

11. The fixing device as claimed in claim 10, wherein the insertion member has a body and a head connected with the body, the body of the insertion member has a recessed area and a first locking portion which is located in the recessed area and adjacent to the head.

12. The fixing device as claimed in claim 9, wherein the end wall has two installation holes, a fixing member and two installation members which are connected to the fixing member, the fixing member is fixed to the bracket, and the installation members extend through the installation holes of the end wall of the bracket respectively.

13. The fixing device as claimed in claim 12, wherein each installation member has a movable rectangular portion, a cylindrical portion and a spring, the rectangular portion is slidably connected relative to the cylindrical portion, the spring applies a force to the rectangular portion so that the rectangular portion extends beyond the fixing member and located at a pre-set position.

14. The fixing device as claimed in claim 9, wherein the side wall has a window, the operation portion of the engaging member slidably contacts an inside of the window, so that the engaging member is movable relative to the insertion member to control the first protrusion of the arm to protrude beyond or to retract toward the slot of the insertion member.

15. The fixing device as claimed in claim 9, wherein the bracket has a first guide portion, the engaging member has a second guide portion, a guide member is located between the first and second guide portions.

16. The fixing device as claimed in claim 11, wherein the first locking portion of the insertion member is locked to a locking device of a chassis.

17. The fixing device as claimed in claim 8, wherein the engaging member has a second protrusion which is locked to a locking device of a chassis.

18. A slide assembly for being installed to a rack which has multiple columns, each column having multiple holes which comprises a first hole, a second hole and a third hole located between the first and second holes, a chassis connected to the rack by two slide assemblies, the chassis has a locking device, each slide assembly comprising:

a first rail;

a second rail being slidable relative to the first rail;

a bracket connected to the first rail, the bracket having a side wall and an end wall, the side wall having a window, the end wall substantially perpendicularly connected to the side wall, the end wall having two installation holes and a through hole;

a fixing member fixed to the bracket;

a third rail slidably connected between the first and second rails;

an insertion member connected to the end wall of the bracket and partially extending through the through hole of the end wall of the bracket, the insertion member having a slot and a locking portion which is located corresponding to the locking device of the chassis;

an engaging member slidably connected relative to the bracket, the engaging member having an operation portion and an arm, the operation portion located corresponding to the window of the side wall of the bracket, the arm extending through the slot of the insertion member and having a first protrusion;

a resilient member providing a force to the engaging member to extend the first protrusion beyond the slot of the insertion member;

two installation members connected to the fixing member and extending through the installation holes of the end wall of the bracket respectively; and

the two installation members installed through the first and second holes of the column of the rack respectively, the insertion member inserted into the third hole of the column of the rack, the arm of the engaging member extending through the slot of the insertion member, the first protrusion of the engaging member extending beyond the slot of the insertion member and engaged with the column of the rack by the force of the resilient member applied to the engaging member, when the slide assembly is installed to the rack, the first locking portion of the insertion member is engaged with the locking device of the chassis.

19. The slide assembly as claimed in claim 18, wherein the operation portion of the engaging member slidably contacts an inside of the window, the engaging member is movable relative to the insertion member to control the first protrusion of the arm to protrude beyond or to retract toward the slot of the insertion member.
