[ field of technology ]

The present invention relates to a server device, and more particularly, to a server chassis.

[ background Art ]

Generally, in the process of assembling a server chassis, a locking tool is usually used to lock an upper cover on a rack to complete an assembly operation of fixedly combining the cover with the rack. However, in the process of locking and assembling, a plurality of screws are usually required to be additionally prepared and a complicated locking action is performed, which is very time-consuming and labor-consuming and increases the production cost. And when the upper cover is to be detached, the upper cover can be removed from the rack after all screws are required to be detached in a troublesome manner. The fastening device is arranged on the cover, so that the cover can be directly arranged and fixed on the frame, the tool-free assembly operation is realized, and the mounting operation of assembling the cover on the frame or disassembling the cover from the frame is effectively facilitated. Generally, however, after the cover is combined with the frame by using the fastening device, in order to avoid the cover being removed by other personnel outside, a protection foolproof mechanism is actually required to be designed, so that the cover cannot be easily removed from the frame by the external personnel through the fastening device, and the cover is worthy of careful thinking and further research by practitioners.

[ invention ]

The invention aims to provide a server case which can be assembled quickly and has good practicability.

In order to solve the technical problems, the server case of the invention comprises a frame, a case cover detachably arranged on the frame, an elastic fixing module combined on the case cover and positioned in the case cover, and a safety lock module.

The frame comprises a bottom plate and two side plates extending from two opposite sides of the bottom plate to a direction away from the bottom plate. The front side of one side plate is provided with a limiting module which is provided with a guiding part and a limiting sliding groove part connected with the guiding part.

The shell cover comprises a cover body, two extension plates extending from two opposite ends of the cover body to the direction of the side plates of the frame, and a perforation unit penetrating through the cover body. The extension plate corresponds to the side plate. The perforation unit is close to one of the extension plates, and the extension plate corresponds to the side plate with the limit module. The perforation unit is provided with a first perforation and a second perforation, and the second perforation is positioned between the first perforation and the corresponding extension plate.

The elastic fixing module is combined on the cover body of the cover and comprises an elastic sheet unit which is combined on the inner side surface of the cover body and corresponds to the perforation unit, and a clamping convex column which is arranged on the elastic sheet unit, extends from the elastic sheet unit to the direction of the limiting module and can be limited on the limiting sliding groove part. The extending plate of the shell cover is combined with the side plate of the frame and enables the clamping convex column to prop against the guiding part of the limiting module, the extending plate is moved forward to drive the clamping convex column to move from the guiding part to the direction of the limiting sliding groove part, the clamping convex column moves into the limiting sliding groove part and enables the clamping convex column to be clamped in the limiting sliding groove part, and at the moment, the shell cover is fixed on the frame.

The safety lock module comprises a base fixed on the inner side surface of the cover body and a locking unit penetrating through the base and corresponding to the second through hole of the through hole unit. The locking unit is detachably combined with the elastic sheet unit. The locking unit can move between a fixed position and an unfixed position relative to the elastic sheet unit. When the locking unit is at the non-fixed position, the elastic sheet unit is not combined with the locking unit; when the elastic sheet unit is fixed at the fixed position, the locking unit is fixedly combined with the elastic sheet unit, so that the elastic sheet unit is fixed on the locking unit and cannot move up and down.

When the clamping convex column of the shell cover is clamped into the limit sliding groove part of the machine frame and the shell cover is fixed on the machine frame, the locking unit is adjusted to move to the fixed position, at the moment, the elastic sheet unit is fixed on the locking unit and cannot move up and down, and the clamping convex column cannot move from the limit sliding groove part to the direction of the guide part and cannot move away from the limit module.

Compared with the prior art, the server case is detachably combined with the design of the elastic sheet unit by the locking unit of the safety lock module and is matched with the coincidental concept that the locking unit can move between the fixed position and the non-fixed position relative to the elastic sheet unit. When the clamping convex column of the shell cover is clamped into the limit sliding groove part of the machine frame and the shell cover is fixed on the machine frame, the locking unit is adjusted to move to the fixed position, at the moment, the elastic sheet unit is fixed on the locking unit and cannot move up and down, and the clamping convex column cannot move from the limit sliding groove part to the direction of the guide part and cannot move away from the limit module, so that the problem that the shell cover is removed by other outside personnel at will when the shell cover is fixed on the machine frame is effectively avoided.

[ detailed description ] of the invention

Referring to fig. 1 and 2, an embodiment of a server chassis of the present invention includes a frame 1, a cover 2 detachably disposed on the frame 1, an elastic fixing module 3 combined on the cover 2 and located in the cover 2, and a security lock module 4.

The frame 1 comprises a bottom plate 11 and two side plates 12 extending from opposite sides of the bottom plate 11 in a direction away from the bottom plate 11. The front side of one side plate 12 is provided with a limiting module 121, and the limiting module 121 is provided with a guiding part 122 and a limiting sliding groove part 123 connected with the guiding part 122.

The cover 2 comprises a cover body 21, two extending plates 22 (only one is shown in the view) extending from opposite ends of the cover body 21 toward the side plates 12 of the frame 1, and a perforation unit 23 penetrating the cover body 21. The extension plate 22 corresponds to the side plate 12. The perforation unit 23 is close to one of the extension plates 22, and the extension plate 22 corresponds to the side plate 12 with the limiting module 121. The perforation unit 23 has a first perforation 231 and a second perforation 232, and the second perforation 232 is located between the first perforation 231 and the corresponding extension plate 22.

The elastic fixing module 3 is combined on the cover 21 of the cover 2, and comprises an elastic sheet unit 31 combined on the inner side surface of the cover 21 and corresponding to the perforation unit 23, and a clamping convex column 32 arranged on the elastic sheet unit 31 and extending from the elastic sheet unit 31 to the direction of the limiting module 121 and capable of being limited on the limiting chute portion 123. The extending plate 22 of the housing cover 2 is combined with the side plate 12 of the housing 1 and makes the engaging protrusion 32 abut against the guiding portion 122 of the limiting module 121, and the extending plate 22 is moved forward to drive the engaging protrusion 32 to move from the guiding portion 122 toward the limiting sliding slot portion 123, and the engaging protrusion 32 moves into the limiting sliding slot portion 123 and makes the engaging protrusion 32 be engaged with and limited at the limiting sliding slot portion 123, at this time, the housing cover 2 is fixed on the housing 1.

The safety lock module 4 includes a base 41 fixed on the inner side of the cover 21, and a locking unit 42 penetrating through the base 41 and corresponding to the second through hole 232 of the through hole unit 23. The locking unit 42 is detachably coupled to the elastic sheet unit 31. The locking unit 42 is movable between a fixed position and an unfixed position relative to the elastic sheet unit 31. In the non-fixed position, the locking unit 42 is not combined with the elastic sheet unit 31 (see fig. 4); in the fixing position, the locking unit 42 is locked to the elastic sheet unit 31, so that the elastic sheet unit 31 is fixed on the locking unit 42 and cannot move up and down (see fig. 8).

When the engaging protrusion 32 of the cover 2 is engaged with the limiting chute 123 of the frame 1 and the cover 2 is fixed on the frame 1, the locking unit 42 is adjusted to move to the fixed position, at this time, the elastic sheet unit 31 is fixed on the locking unit 42 and cannot move up and down, and the engaging protrusion 32 cannot move from the limiting chute 123 to the direction of the guiding portion 122 and cannot move away from the limiting module 121.

Referring to fig. 2, 3, 4, 5 and 6, when assembling, the extension plate 22 of the cover 2 is combined with the side plate 12 of the frame 1, and the extension plate 22 is moved forward to drive the engaging protrusion 32 to abut against the guiding portion 122 of the limiting module 121 (see fig. 5). Then, the extending plate 22 is further moved forward to drive the engaging protrusion 32 to move from the guiding portion 122 toward the limiting chute portion 123 of the limiting module 121, and the engaging protrusion 32 is moved into the limiting chute portion 123, so that the engaging protrusion 32 is engaged with the limiting chute portion 123 (see fig. 6 and 7), and at this time, the housing cover 2 is fixed on the housing 1. Finally, the locking unit 42 of the safety lock module 4 is moved down to the fixing position, so that the locking unit 42 locks the elastic sheet unit 31 combined with the elastic fixing module 3, and at this time, the elastic sheet unit 31 is fixed on the locking unit 42 and cannot move up and down. That is, after the assembly operation of fixing the cover 2 to the frame 1 is completed by moving the engaging protrusion 32 of the elastic fixing module 3 into the limit chute 123, the locking unit 42 of the safety lock module 4 is locked and combined with the elastic sheet unit 31 of the elastic fixing module 3 (see fig. 8), so that the elastic sheet unit 31 is fixed to the locking unit 42, and when the elastic sheet unit 31 is fixed to the locking unit 42, the elastic sheet unit 31 cannot move up and down, and since the engaging protrusion 32 is integrally formed on the elastic sheet unit 31, the engaging protrusion 32 cannot move down to move out of the limit chute 123, and cannot move from the limit chute 123 to the direction of the guide 122 to fail to move away from the limit module 121, thereby effectively ensuring that the cover 2 is fixed to the frame 1. It should be noted that, in the present embodiment, the locking unit 42 of the security lock module 4 has a screw head 421, the screw head 421 has a molding hole 422 for a special locking tool (not shown), in short, the molding hole 422 of the screw head 421 of the locking unit 42 is in a special shape, and the special locking tool needs to be matched to combine with the molding hole 422 and drive the screw head 421 to rotate downwards to lock the elastic sheet unit 31 or drive the screw head 421 to unscrew upwards and separate the locking unit 42 from the elastic sheet unit 31, so that an irrelevant person cannot adjust the locking unit 42 to rotate through a general locking tool, and the protection mechanism of the security lock module 4 combining with the elastic sheet unit 31 is effectively increased. In the embodiment, the molding hole 422 of the screw head 421 is a six-star hole, but not limited thereto. Incidentally, in the present embodiment, when the locking unit 42 is at the non-fixed position, the locking unit 42 is not combined with the elastic sheet unit 31 and the screw 421 of the locking unit 42 does not exceed the cover 21 (see fig. 4) of the cover 2, but is not limited thereto.

In particular, in the present embodiment, the elastic sheet unit 31 of the elastic fixing module 3 has a fixing side 311 fixed on the inner side surface of the cover 21, an elastic body 312 extending from the fixing side 311 toward the limiting module 121, and a pressing portion 313 protruding from the elastic body 312 and corresponding to the first through hole 231 of the through hole unit 23, and protruding from the first through hole 231. The engaging protrusion 32 is disposed on the elastic body 312 and extends from the elastic body 312 toward the direction of the limiting module 121. Referring to fig. 2, 4 and 9, when the cover 2 is fixed on the frame 1 and the locking unit 42 of the safety lock module 4 is at the non-fixed position, the pressing portion 313 is pressed and moves the elastic body 312 downward to synchronously drive the engaging protrusion 32 to move out of the limiting chute portion 123, at this time, the extension plate 22 of the cover 2 can be moved backward to drive the engaging protrusion 32 to move away from the limiting module 121 along the guiding portion 122 and in a direction away from the limiting chute portion 123, so that the cover 2 is moved away from the frame 1. Further, when the cover 2 is to be detached from the frame 1, the locking unit 42 of the safety lock module 4 is first unscrewed and the locking unit 42 is separated from the elastic sheet unit 31, and then the locking unit 42 of the safety lock module 4 is at the non-fixed position. Then, the pressing portion 313 of the elastic sheet unit 31 is pressed again, so that the elastic body 312 moves downward to synchronously drive the engaging protrusion 32 to move out of the limiting chute portion 123 (see fig. 9). Finally, the extension plate 22 of the housing cover 2 is moved backward to drive the engaging protrusion 32 to move away from the limiting module 121 along the guiding portion 122 and away from the limiting sliding slot portion 123, so that the housing cover 2 is moved away from the frame 1.

In addition, in the present embodiment, the elastic sheet unit 31 further has a coupling seat 314 riveted to the elastic body 312 for locking and coupling the locking unit 42 of the safety lock module 4. When the fixing position is reached, the locking unit 42 is locked and combined with the combining seat 314 of the elastic sheet unit 31, and the elastic sheet unit 31 is fixed on the locking unit 42, at this time, the elastic sheet unit 31 cannot move up and down. In short, the locking unit 42 of the safety lock module 4 locks the coupling seat 314 of the elastic body 312, so that the elastic sheet unit 31 is fixed on the locking unit 42 and cannot move up and down, but is not limited thereto.

The locking unit 42 of the safety lock module 4 is detachably combined with the design of the elastic sheet unit 31, and is matched with the coincidence that the locking unit 42 can move between the fixed position and the non-fixed position relative to the elastic sheet unit 31. When the engaging protruding column 32 of the cover 2 is engaged with the limiting sliding groove 123 of the frame 1 and the cover 2 is fixed on the frame 1, the locking unit 42 is adjusted to move to the fixed position, at this time, the elastic sheet unit 31 is fixed on the locking unit 42 and cannot move up and down, and the engaging protruding column 32 cannot move from the limiting sliding groove 123 to the direction of the guiding portion 122 and cannot move away from the limiting module 121, so that the problem that the cover 2 is removed by other external personnel at will when the cover 2 is fixed on the frame 1 is effectively ensured.

Referring to fig. 2, 4, 5, 6, 7 and 9, it is to be noted that in the present embodiment, the base 41 of the security lock module 4 has a base 411 and two bonding sheets 412 disposed at opposite ends of the base 411 and configured to be fixed on the inner side of the cover 21. The safety lock module 4 further includes a limiting member 43 for limiting the elastic body 312 of the elastic sheet unit 31. The limiting member 43 has a rod body 431 extending from the base 411 of the base 41 toward the direction of the elastic sheet unit 31 and penetrating the elastic sheet unit 31, and a limiting seat 433 disposed on the rod body 431. The rod 431 has a coupling end 432 passing through the elastic sheet unit 31, and the limiting seat 433 is disposed on the coupling end 432. When the elastic body 312 moves downward and abuts against the limiting seat 433, the elastic body 312 is blocked by the limiting seat 433 and cannot move downward. That is, in the process of moving the elastic body 312 downward, the downward movement range of the elastic body 312 can be limited by the design that the elastic body 312 abuts against the limiting seat 433, so as to avoid the risk of damage caused by the overpressure of the elastic sheet unit 31 of the elastic fixing module 3 or the problem that the clamping convex column 32 cannot be accurately clamped in the limiting chute portion 123 due to the deviation of the clamping convex column 32 from the guiding portion 122 of the limiting module 121 caused by the overpressure of the elastic sheet unit 31 in the assembling process. Incidentally, in the present embodiment, the fixing device further includes a plurality of first fixing members 5 for fixing the fixing side 311 of the elastic sheet unit 31 to the inner side of the cover 21, and a plurality of second fixing members 6 for fixing the engaging sheet 412 of the security lock module 4 to the inner side of the cover 21. The first fixing member 5 is inserted through the fixing side 311 of the cover 21 and the elastic sheet unit 31, and fixes the fixing side 311 to the cover 21, and the second fixing member 6 is inserted through the cover 21 and the connecting sheet 412, and fixes the connecting sheet 412 to the cover 21, but not limited thereto.

In summary, the locking unit 42 of the security lock module 4 is detachably combined with the design of the elastic sheet unit 31, and the locking unit 42 is matched with the puzzle that the elastic sheet unit 31 can move between the fixed position and the non-fixed position. When the engaging protruding column 32 of the cover 2 is engaged with the limiting sliding groove 123 of the frame 1 and the cover 2 is fixed on the frame 1, the locking unit 42 is adjusted to move to the fixed position, at this time, the elastic sheet unit 31 is fixed on the locking unit 42 and cannot move up and down, and the engaging protruding column 32 cannot move from the limiting sliding groove 123 to the direction of the guiding portion 122 and cannot move away from the limiting module 121, so that the problem that the cover 2 is removed by other external personnel at will when the cover 2 is fixed on the frame 1 is effectively ensured.

The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
