DETAILED DESCRIPTION OF EMBODIMENTS

[0023] Principles of example embodiments disclosed herein will now be described with reference to various example embodiments illustrated in the drawings. It should be appreciated that description of those embodiments is merely to enable those skilled in the art to better understand and further implement example embodiments disclosed herein and is not intended for limiting the scope disclosed herein in any manner.

[0024] FIG. 1 is a diagram illustrating an application environment 100 of an embodiment according to the present disclosure. As shown in FIG. 1, a rack 1 is a common device for supporting or accommodating a machine unit 2 in a data center or storage system. The machine unit 2 for example may be a server, a storage unit or the like. Since the machine unit 2 needs to be mounted on the rack, the machine unit 2 may also be called a target device. When the machine unit 2 is mounted on the rack 1, a rod 4 is inserted through the machine unit 2 into the rack 1, thereby securing the machine unit 2 to the rack 1. The rack 1 may be mounted with a holding device 3 for use in cooperation therewith, and the holding device 3 may be used in cooperation with the rod 4 to hold the machine unit 2 on the rack 1 via the rod 4.

[0025] It should be appreciated that the embodiment of the present disclosure is described mainly in conjunction with the rack, but this is only exemplary and not limiting. It will be apparent from the following description that the device described herein is also adapted for other devices and environments.

[0026] Now referring to FIGS. 2-4, the structure and operation principle of the holding device 3 and rod 4 are described in detail. For the sake of brevity, relevant devices such as the rack and machine unit are omitted in the figures. FIG. 2 is a schematic view of the rod 4 and the holding device 3 which are engaged together, and FIG. 3 shows the rod 4 alone. As shown in FIGS. 2-3, the rod 4 includes a first end 11 and a second end 12. The first end 11 will be shown in detail in FIG. 4.

[0027] The first end 11 of the rod 4 is provided with a bolt 6. When the rod 4 is inserted through the machine unit into the rack, the rod 6 connects the first end 11 to the rack, thereby securing the machine unit to the rack. To this end, as shown in FIG. 2, the holding device 3 comprises a nut which may be used in cooperation with the bolt 6 at the first end 11 of the rod 4 to secure the machine unit 2 onto the rack 1 via the rod 4.

[0028] In addition, as shown in FIGS. 3-4, in some embodiments, the rod 4 may further comprise a stopper 7 disposed at the first end 11 for use in cooperation with the bolt 6. Although the figure shows two stoppers, the number of the stoppers 7 may be one or more than two.

[0029] As shown in FIGS. 2-3, the rod 4 further comprises the second end 12 provided with a manually rotatable handle 5. With the aid of the handle 5, a mounting tool (e.g., a screw driver) would be unnecessary during the user's operation so that the user can conveniently install and detach the rod.

[0030] FIG. 5a shows a thread with a trapezoidal cross-sectional shape (also called thread form), namely, a trapezoidal thread according to an embodiment of the present disclosure. In contrast, FIG. 5b shows a thread with a triangular cross-sectional shape, namely, a triangular thread in the prior art. As shown in FIG. 5a, an external thread 8 and an internal thread 9 have corresponding trapezoidal threads. As shown in FIG. 5b, an external thread 8′ and an internal thread 9′ have corresponding triangular threads. The internal threads 9 and 9′ may be used to secure the nut of the holding device 3, and external threads 8 and 8′ may be used for the bolt of the rod 4. The Inventors fabricate the rod 4 and holding device 3 having two types of threads, and perform contrast test for them. It has already been proved during the transportation test and vibration test that the trapezoidal thread has a performance remarkably better than the triangular thread, and the machine unit is not easy to loosen, thereby substantially reducing possibility of data loss due to mechanical reasons. As compared with the triangular thread, the trapezoidal thread has more corners. That is, the triangular thread only includes one corner at the end, while the trapezoidal thread includes two corners on both sides of the end. This enables the trapezoidal thread to have a better shock-resistance performance than the triangular thread.

[0031] In some embodiments, the trapezoidal thread may conform to ACME thread specification. As an example, the trapezoidal thread may be of 0.2500-16.0 ACME-3G specification. Certainly, this is only an example. The trapezoidal thread may be designed and manufactured according to any industry specification currently known or to be developed in the future.

[0032] In addition, in some embodiments, the holding device 3 may be made of plastics. Due to property differences of plastic and metallic materials, the holding device 3 made of plastics may achieve a better shock-resistance performance while ensuring mechanical strength. In addition, the holding device 3 made of plastics may substantially reduce the cost of manufacture, since the plastics have lower costs than metal.

[0033] In some embodiments, the holding device 3 may be integrally formed from plastics and thus it is easy to be assembled. As an example, the holding device may be formed by injection molding, and the plastics may be polycarbonate and acrylonitrile-butadiene-styrene copolymer (PC+ABS) or glass fiber reinforced polycarbonate (PC+glass fiber).

[0034] The foregoing has illustrated the principle and spirit of the present disclosure in conjunction with several specific examples. The embodiments of the present disclosure may secure the machine unit to the rack more firmly and enhance the shock-resistance performance, thereby avoiding data loss caused by mechanical factors. In addition, since the holding device may employ a plastic material, the shock-resistant performance can be further enhanced and the manufacturing costs may be reduced substantially. It is appreciated that the above embodiments described in conjunction with figures are not mutually exclusive. Instead, features described in conjunction with these embodiments may be arbitrarily arranged and combined as required. The scope of the present disclosure is not limited in this aspect.

[0035] Although the present disclosure has been described with reference to various embodiments, it should be understood that the present disclosure is not limited to the disclosed embodiments. The present disclosure is intended to cover various modifications and equivalent arrangements included in the spirit and scope of the appended claims. The scope of the appended claims meets the broadest explanations and covers all such modifications and equivalent structures.
