The present invention relates to a fastening device and, in particular, to a fastening device that enables fast securement and provides shockproof protection.
With advancements in the information and computer industries, computers have become indispensable in modern life. In a computer system, a hard disk is a medium for storing and reading data and also serves as a storage device for storing a huge amount of data. The hard disk installed in the computer sometimes undergoes undesirable vibrations, and the problem is even worse with an industry computer, for it may be used in a vibrating environment. The hard disk in the vibrating environment not only has a reduced lifespan but also may malfunction all of sudden.
Furthermore, in a conventional computer system or an electronic device, by increasing the number of the data storage devices (e.g. a hard disk or an optical hard drive), the greater the amount of data can be stored. At present, after fixing the data storage device to a rack, the data storage device can be assembled into the computer system or the electronic device by fixing the rack thereto. The data storage device is fixed to the rack by screw-fastening, in which a bolt needs to be aligned with a threaded hole and then screwed into the threaded hole at two sides of the data storage device, which results in many shortcomings such as inconvenient and time-consuming assembly and disassembly.
Accordingly, the aim of the present invention is to improve the conventional hard disk securement method so as to overcome the above-mentioned shortcomings which are well known in related industries.
It is an object of the present invention to provide a fastening device for securing and protecting an electronic device, which also enables fast securement and provides shockproof protection.
It is another object of the present invention to provide a fastening device which has a simple structure and facilitates convenient assembly.
Accordingly, the present invention provides a fastening device for securing and protecting an electronic device. The electronic device includes at least one assembly hole. The fastening assembly includes a fastening assembly and a plate. The fastening assembly includes a buffer and a fastening element inserted through the buffer. The fastening element includes a rod portion, a fastening portion at one end of the rod portion, and a head portion at the other end of the rod portion. The fastening portion is fastenable in the assembly hole. The plate includes a first positioning hole and a second positioning hole communicating with the first positioning hole, wherein a diameter of the first positioning hole is greater than a diameter of the second positioning hole, and a diameter of the head portion is less than the diameter of the first positioning hole and greater than the diameter of the second positioning hole, so that the head portion is engaged with the second positioning hole, and the electronic device is secured over the plate.
It is preferable that the buffer further includes two flanges, a recess between the two flanges, and a through hole for insertion of the rod portion. A diameter of the through hole is greater than or equal to a diameter of the rod portion. An outer diameter of each of the flanges is greater than the diameter of the head portion and the diameter of the first positioning hole, so the buffer can contact against the plate corresponding to the first positioning hole and the second positioning hole.
It is preferable that the plate further includes a first surface, a second surface opposite to the first surface, and an extension hole passing through the first surface and the second surface, wherein a first direction is between the first positioning hole and the second positioning hole, a second direction is perpendicular to the first direction, and the extension hole is formed along the first direction and between the first positioning hole and the second positioning hole.
It is preferable that the fastening device further comprises two protruding portions protruding from the second surface, the buffer is in contact against the first surface, the head portion and the two protruding portions are disposed correspondingly, thereby preventing removal of the head portion from the second positioning hole.
The disclosure will become more fully understood from the detailed description and the drawings given herein below for illustration only, and thus does not limit the disclosure, wherein:
Detailed descriptions and technical contents of the present invention are illustrated below in conjunction with the accompany drawings. However, it is to be understood that the descriptions and the accompany drawings disclosed herein are merely illustrative and exemplary and not intended to limit the scope of the present invention.
Referring to
In the present invention, the fastening device for securing and protecting the electronic device 10 comprises a fastening assembly 100 and a plate 200. The fastening assembly 100 comprises a buffer 110 and a fastening element 120 inserted through the buffer 110. The buffer 110 comprises two flanges 112 and a recess 114 between the two flanges 112. The fastening element 120 includes a rod portion 124, a fastening portion 122 at one end of the rod portion 124, and a head portion 126 at the other end of the rod portion 124, wherein the fastening portion 122 is fastenable in the assembly hole 20.
As shown in the figures, the electronic device 10 preferably includes four assembly holes 20. In correspondence to the four assembly holes 20, there are provided with four fastening assemblies 100, and four first positioning holes 210 and four second positioning holes 220 of the plate 200, so as to secure the electronic device 10 over the plate 200. However, for ease of illustration, only one assembly hole 20, and one fastening assembly 100, one first positioning hole 210 and one second positioning hole 220 corresponding to this assembly hole 20 are described hereinafter as an example.
In the embodiment shown in
Furthermore, the fastening device comprises a pad 130 made of a metal material. The pad 130 is disposed between the buffer 110 and the head portion 126, thereby preventing the buffer 110 from directly rubbing against a surface of the plate 200, prolonging the lifespan of the buffer 110, and enabling the fastening assembly 100 to be movably assembled to the plate 200 with ease. It is preferable that the buffer 110 is made of rubber or silicon, or consists of a spring or other suitable soft or flexible materials.
In
Referring to
In the present embodiment, the plate 200 further includes a first surface 202, a second surface 204 opposite to the first surface 202, and an extension hole 230 passing through the first surface 202 and the second surface 204. As shown in
When the fastening assembly 100 is screwed into the assembly hole 20 of the electronic device 10, the buffer 110 can be a damper (vibration absorber) which is a material having elastic deformation capability, so as to prevent vibrations from being transmitted to the electronic device 10 via the fastening assembly 120 to affect operation performance. Furthermore, a length of the rod portion 124 between the head portion 126 and the fastening portion 122 is less than or equal to a height of the buffer 110, so as to facilitate elastic deformation of the buffer 110. In a preferable embodiment, when the head portion 126 of the fastening assembly 100 is assembled in the first positioning hole 210 of the plate 200 and is moved toward the second positioning hole 220 (i.e. along the first direction F), since the outer diameter of the head portion 126 is greater than the diameter of the second positioning hole 220, the head portion 126 can be engaged with the second positioning hole 220 in a direction perpendicular to the plate 200, and thereby the electronic device 10 is secured over the plate 200.
In the embodiment shown in
Referring to
In the embodiment shown in
Finally, the plate 200 further includes a restriction plate 240. The restriction plate 240 protrudes from an edge of the first positioning hole 210 on the second surface 204, so as to prevent the head portion 126 from moving toward a direction opposite to the second positioning hole 220. Accordingly, the fastening assembly 100 of the present invention enables fast securement, provides shockproof protection, has a simple structure, and facilitates convenient assembly.
It is to be understood that the above descriptions are merely the preferable embodiment of the present invention and are not intended to limit the scope of the present invention. Equivalent changes and modifications made in the spirit of the present invention are regarded as falling within the scope of the present invention.
