The present invention relates to a server and, in particular, to a server having slide rail fastening structure mounted to a pillar having different shaped positioning holes.
A conventional server rack usually has round positioning holes on its pillars. However, the conventional server rack cannot match all types of chassis since chassis have various specifications. To solve this problem, a fastener, like a fastening plate, is used to convert a square hole to round hole, so that slide rails, chassis or other components can be mounted to the server rack. However, no fasteners are specially designed for a slide rail with a locking mechanism.
It is an objective of the present invention to provide a server having a slide rail fastening structure capable of converting positioning holes (e.g. converting a round hole to a square hole).
It is another objective of the present invention to provide a server having a slide rail fastening structure. The structure is simple and allows for easy assembly and easy manufacture at low costs.
Accordingly, the present invention provides a server having a slide rail fastening structure. The server has a rack, a support and a bracket. The rack includes two pillars and a slide rail assembly. The slide rail assembly is arranged longitudinally with respect to the rack and mounted to the two pillars. Each pillar includes a plurality of round holes spaced apart from each other. The support includes a body and includes a first plate and a second plate connected to the body at two sides thereof. The first plate is fixed to at least one of the round holes of a corresponding one of the pillars. The second plate includes a plurality of openings, the opening is of a shape different from the round hole and used to position the slide rail assembly. The bracket includes a first board and a second board perpendicularly connected to the first board, the first board is arranged corresponding to the first plate, the second board is arranged parallel to the slide rail assembly and assembled to one end of the slide rail assembly, and thereby the bracket and this end move together with respect to the rack.
According to one embodiment, the slide rail assembly includes a fixing plate, a resilient hook and an elastic element. The fixing plate includes a plurality of ports, the resilient hook is disposed adjacent to the fixing plate, and the elastic element is fixed to any of the ports, so that the slide rail assembly can be fixed to the second plate of the support. In another embodiment, the server further includes a coupling member coupled to an outer lateral surface of the slide rail assembly. The fixing plate and the resilient hook are disposed on the coupling member and are fastened to respective openings of the support, so that the slide rail assembly can be fixed to the pillar.
The first plate further includes a plurality of protruding flanges and a plurality of through holes penetrating the respective protruding flanges. The protruding flanges are inserted and engaged with the respective round holes. Fastening elements are inserted through the respective round holes and the respective through holes. Therefore, the slide rail assembly can be mounted to the rack having a different shaped positioning hole by means of the support.
In summary, the support and the bracket are used to convert shapes of the positioning holes, so that the slide rail assembly and chassis of different specifications can be assembled to the rack without the need of changing the present rack structure (e.g. the round hole or a different shaped positioning hole). The server has a simple slide rail fastening structure (i.e. the support and the bracket) which allows for easy assembly and manufacture at low costs.

The first board 151 is arranged corresponding to the first plate 142, the second board 152 is arranged parallel to the slide rail assembly 13 and assembled to one end of the slide rail assembly 13, and thereby the bracket 15 and this end (the inner slide rail 132) can move together with respect to the rack 11.
The slide rail assembly 13 further includes a fixing plate 171, a resilient hook 172 and an elastic element 16. The fixing plate 171 includes a plurality of ports 174, the resilient hook 172 is disposed adjacent to the fixing plate 171, and the elastic element 16 is fixed to any of the ports 174. The resilient hook 172 is arranged corresponding to and detachably engaged with one of the openings 144 of the second plate 143, so that the slide rail assembly 13 is fixed to the pillar 12 by means of the support 14. In detail, the present embodiment further includes a coupling member 17 coupled to an outer lateral surface of the slide rail assembly 13, the fixing plate 171 is preferably bent from one end of the coupling member 17, one end of the resilient hook 172 is pivotally fixed to the coupling member 17, and the other end of the resilient hook 172 protrudes beyond the fixing plate 171 to be engaged with the corresponding opening 144. As shown in
The first plate 142 further includes a plurality of protruding flanges 1421 and a plurality of through holes 1422 penetrating the respective protruding flanges 1421, and the protruding flanges 1421 are inserted and engaged with the respective round holes 121. Fastening elements 18 such as screws or bolts are inserted through the respective round holes 121 and the respective through holes 1422 so as to fix the support 14 to the pillar 12. Accordingly, the slide rail assembly 13 can be fixed to the pillar 12 by means of the first plate 142 and the second plate 143 having different shaped positioning holes (i.e. the round protruding flanges 1421 and the openings 144).
In the present embodiment, the support 14 preferably has three protruding flanges 1421 of round shape and three openings 144. The three protruding flanges 1421 and the three openings 144 are arranged corresponding to three round holes 121 of the pillar 12, so that the protruding flanges 1421 are fixed to the pillar 12, and the openings 144 are fixed to the slide rail assembly 13. In the present embodiment, the support 14 and/or the bracket 15 are sized to substantially cover an area of the three round holes 121, so that the support 14 and the bracket 15 can efficiently fix the slide rail assembly 13. In alternative embodiments, the support 14 and/or the bracket 15 can be sized to cover an area larger than or smaller than the area of the three round holes 121, and configuration may vary according to requirement. By using the support 14 and the bracket 15, the slide rail assembly 13 and the chassis 2 of different specifications can be assembled to the rack 11 without changing the present structure (the round holes 121 or different shaped holes) of the rack 11, so assembling is fast and easy, and the slide rail fastening structure (i.e. the support 14 and the bracket 15) is simple, thereby allowing for easy manufacture at low costs.

The connection member 21 includes a fastening hole 211 disposed corresponding to the fastening hook 203, and the fastening hook 203 is rotatable to be fastened to the fastening hole 211. The connection member 21 includes a flat plate 212, two bent portions 213 connected to the flat plate 212, and an inverse hook 214 extended toward the bent portions 213. The inverse hook 214 is detachably engaged with the fastening hook 203, so that the locking structure 20 is fastened to the pillar 12. Side edges of the two bent portions 213 are in contact with the pillar 12, and a fastening element 22 is inserted through the flat plate 212 to fasten the connection member 21 to the pillar 12.
The locking structure 20 is operated by the following way. When the handle 202 is rotated to drive rotation of the fastening hook 203. An edge of the handle 202 pushes a bottom of the fastening hook 203, so that a hook portion 205 is tilted upwards to be detached from the inverse hook 214 of the connection member 21. When the operator continues to exert a force to the handle 202 to pull it in a direction away from the rack 11, the bracket 15 and the inner slide rail 132 can be pulled away from the chassis 2. At this time, the resilient element 204 stretches and stores a potential energy for restoring the fastening hook 203 to its initial position. When the operator releases the handle 202, the fastening hook 203 is restored by the resilient element 204, so the hook portion 205 returns to its original position, and then the operator can push back the chassis 2. The hook portion 205 has a slope (not labelled), so that the hook portion 205 can be smoothly restored to its original position and engaged with the inverse hook 214 to achieve a locked state.
This embodiment includes the fixing element 19 to fix the locking structure 20 to the connection member 21 (the pillar 12). By this way, the slide rail assembly 13 can be securely fastened to the pillar 12.
