BACKGROUND

1. Technical Field
The technical field relates to a fixing member, particularly to a fixing member of a rack server with a large flexibility in use.
2. Related Art
A server is a core computer used to serve all other computers in the network system and provides hard disk and printing functions, as well as sharing all the resources in the network with every user. Therefore, a server is a replaceable computer system which can work independently. A common configuration of the server system is installing a plurality of hard disks in the chassis of the server, and a plurality of chassis is integrally arranged on a rack, thereby forming a rack type sever with stacked and serially-linked chassis.
However, since the attraction force of the magnets is limited, the magnets easily fall apart, causing the circuit modules to detach from one another when there many circuit modules are needed to be connected together, creating inconvenience in using and teaching.
A conventional means for fixing the server chassis in the rack is locking the chassis on the inner support of the slide, and locking or hooking the outer support of the slide to the fixing hole of the rack so as to fix the outer support of the slide to the rack. Then, the inner support is assembled to the outer support to allow the inner support to slide relative to the outer support. Finally, the inner support and the chassis slide to a fixed position, thereby fixing the chassis to the rack. However, the fixing hole of the rack varies in shape and size, such as a square shape or a round shape, which prohibits the outer support of the same slide from fitting into all racks, largely limiting the slide's flexibility and inconvenience in use.

One side of the main body 102 is connected to a first positioning element 104, and another side of the main body 102 is connected to a second positioning element 106. The second positioning element 106 is disposed corresponding to the first positioning element 104. The fixing column 110 made of metal or alloy is disposed on the main body 102 and one end thereof is fixed onto the chassis slide assembly 200. The main body 102 is able to move to cause a displacement between the fixing column 110 and the main body 102, and also able to rotate along the fixing column 110 as an axis to switch a relative position of the first positioning element 104 and the second positioning element 106, wherein the first positioning element 104 and the second positioning element 106 have different shape.
In the preferred embodiment of the present invention, the shape of the first positioning element 104 is square column shape, and the second positioning element 106 is formed as round column shape or a round hole (as shown in FIG. 4). However, in other different embodiments, the first positioning element 104 is formed as round column shape or a round hole, and the second positioning element 106 is formed as square column shape, which can be changed as needed, and is not limited thereto. Besides, the shape of the first positioning element 104 and the second positioning element 106 can also be formed as other shapes depending on the shape of the rack fixing hole 410 of the rack 400. As shown in FIG. 2, when the rack fixing hole 410 of the rack 400 is formed as a square hole, the first positioning element 104 will be a square column to match to the rack fixing hole 410.
As shown in FIGS. 3 and 4, the main body 102 further includes a fixing tube 107. The fixing column 110 includes an elastic element 112. The fixing column 110 can penetrate the main body 102 through the fixing tube 107 and is fixed to one end of the chassis slide assembly 200. The elastic element 112 which is a compression spring is sleeved on the fixing column 110 and is accommodated into the fixing tube 107. The fixing column 110 further includes a head portion 114 and a pillar portion 116. The size of the head portion 114 is larger than that of the pillar portion 116, which restricts the elastic element 112 in the head portion 114 and the fixing tube 107. The elastic element 112 on the fixing column 110 can provide an elastic force to make sure the main body 102 keep engaging to the chassis slide assembly 200.
One end of the chassis slide assembly 200 includes at least one positioning hole 230 and a fixing hole 240 fixed into the fixing column 110. The main body 102 further includes at least one positioning pillar 108. The at least one positioning pillar 108 protrudes from a surface of the main body 102 and is disposed on a side of the fixing column 110, and thereby being positioned with the chassis slide assembly 200 having at least one positioning hole 230 opened thereon. In the preferred embodiment as shown in FIGS. 3 and 4, each of the fixing members 100 preferably includes two positioning pillars 108 to be positioned with two corresponding positioning holes 230, thereby stably fixing each of the fixing members 100 to the chassis slide assembly 200.
Besides, please refer to FIG. 5, the first positioning element 104 further comprises a buckling element 140 and a through hole 130, the through hole 130 penetrates the first positioning element 104 in a direction perpendicular to the fixing column 110, and one end of the buckling element 140 movably protrudes the through hole 13 to be buckled in the rack fixing hole 410 of the rack 400, and the chassis slide assembly 200 is able to be fixed to the rack 400 accordingly. Two ends of the buckling element 140 further include a protruding part 142 respectively, two limit slots 132 are formed on the first positioning element 104 corresponding to two protruding parts 142, the two protruding parts 142 restrict movement of the buckling element 140 in the two limit slots 132, wherein a size of each of the limit slots 132 is smaller than a size of the through hole 130, and a shape of each of the limit slots 132 is oval shape.
The operation of the single fixing member 100 is simple and easy, and the main body 102 is able to rotate along the fixing column 110 as an axis to switch a relative position of the first positioning element 104 and the second positioning element 106 to match the shape of the rack fixing hole 410, thereby improving the flexibility in use As shown in FIGS. 6-8, the user pulls the fixing member 100 corresponding to the fixing column 110 to allow each of the positioning pillars 108 to be free from the restriction of each of the positioning holes 230, and then the main body 102 can rotate 180 degrees. Meanwhile, the second positioning element 106 exchanges the position with the first positioning element 104, and the main body 102 is released. By the elastic force provided by the elastic element 112, the main body 102 is restored, and each of the positioning pillars 108 and each of the positioning holes 230 are engaged again. Therefore, the fixing member 100 is restored to a stable connection with the chassis slide assembly 200.
Referring to FIGS. 9 and 10, when the rack fixing hole 410 of the rack 400 is formed as a round hole, the second positioning element 106 is formed as a round column or a round hole to be fixed to the corresponding rack fixing hole 420. In a preferred embodiment as shown in FIG. 9, the second positioning element 106 is a round column protruding the main body 102 (top) or a round hole (bottom). However, no matter the second positioning element 106 is formed as a round column or a round hole, the second positioning element 106 can be fixed to the rack fixing hole 420.
When the second positioning element 106 is a round column, the round column can be directly inserted into the rack fixing hole 420 which is formed as a round hole. However, when the second positioning element 106 is a round hole, an extra fixing element 430 is needed to be fixed to the second positioning element 106. The fixing element 430 can be a screw, a bolt, a bond, a rivet, or any other suitable members, and is not limited thereto. In other words, the fixing element 430 needs to penetrate the rack fixing element 420 of the rack 400, and then is fixed to the second positioning element 106 to achieve the goal of fixing the rack 400.
By using a single fixing member 100 with a first positioning element 104 and a second positioning element 106 which respectively have different shapes, different rack fixing holes 410/420 can also be matched with the same fixing member 100, and the same fixing member 100 can also be fixed to different racks 400, thereby improving the using flexibility.
Although the present invention has been described with reference to the foregoing preferred embodiments, it will be understood that the invention is not limited to the details thereof. Various equivalent variations and modifications can still occur to those skilled in this art in view of the teachings of the present invention. Thus, all such variations and equivalent modifications are also embraced within the scope of the invention as defined in the appended claims.
