1. Technical Field
The present invention relates to a slide rail device, and more particularly, to a tool-free rapid assembly/disassembly slide rail device for an industrial computer, wherein each of a front slide rail and a rear slide rail has an end inserted by rectangular or circular flange positioning blocks of a positioning element and is detachably assembled with a resilient retaining element, so that the positioning element is retained by the resilient retaining element to allow rapid assembly and disassembly of the slide rail device.
2. Description of Related Art
Conventional slide rails for computer equipment or, more particularly, an industrial computer comprise a set of length-adjustable inner and outer slide rails, each having a bent section formed at an outer end thereof. The slide rails are fixed on a front slide rail post and a rear slide rail post of a computer chassis, respectively, via the bent sections. In addition, the inner slide rail has an inner side formed with a slide groove for receiving a corresponding one of slide plates fixed bilaterally on the industrial computer or a host of related equipment, so that the industrial computer or the host can be slid into and drawn out of the computer chassis along the slide rails.
The conventional slide rails for use with computer equipment are fixed on the two slide rail posts of the computer chassis by placing the bent sections adjacent to the slide rail posts and then using screws and nuts to secure the slide rails onto the posts. Therefore, assembly and disassembly of such slide rails is a time-consuming and laborious operation that cannot be done without tools.
A primary objective of the present invention is to provide a tool-free rapid assembly/disassembly slide rail device characterized in that a user can assemble and disassemble the slide rail device rapidly without using tools.
A secondary objective of the present invention is to provide a tool-free rapid assembly/disassembly slide rail device adaptive to slide rail posts having rectangular as well as circular positioning holes.
To achieve these objectives, the present invention provides a slide rail device for computer equipment, and more particularly, a tool-free rapid assembly/disassembly slide rail device characterized in that each of a front slide rail and a rear slide rail has an end formed with a bent positioning portion inserted by rectangular or circular flange positioning blocks of a positioning element, and each of the front and rear slide rails further has a slot formed adjacent to the corresponding bent positioning portion, wherein the slot is detachably assembled with a resilient retaining element. The rectangular or circular flange positioning blocks are inserted in positioning holes on slide rail posts of a chassis and retained in place by the resilient retaining element, thereby allowing the slide rail device to be rapidly assembled to and disassembled from the slide rail posts without using tools.
The invention as well as a preferred mode of use, further objectives and advantages thereof will best be understood by reference to the following detailed description of an illustrative embodiment when read in conjunction with the accompanying drawings, wherein:
Referring to
The front slide rail 1 has an end formed with a bent positioning portion 11. Likewise, the rear slide rail 2 has an end formed with a bent positioning portion 21. The bent positioning portions 11 and 21 are formed respectively with receiving holes 111 and 211. In addition, the front and rear slide rails 1 and 2 are provided respectively with slots 12 and 22 adjacent to the corresponding bent positioning portions 11 and 21.
Each of the positioning elements 3 has a first side provided with protrusions 31 corresponding to the receiving holes 111 and 211 on the bent positioning portions 11 and 21 of the front and rear slide rails 1 and 2, and a second side provided with rectangular flange positioning blocks 32 or circular flange positioning blocks 33 corresponding respectively to rectangular positioning holes 51 or circular positioning holes 52 formed on slide rail posts 5 of a chassis.
Each of the resilient retaining elements 4 is formed with fixing holes 41, a pulling surface 42 at an end of each of the resilient retaining elements 4, and inward-extending retainers 43. The retainers 43 can be fixed in place at an end of, and inward of, each of the slots 12 and 22 of the front and rear slide rails 1 and 2 by rivets or screws which pass through the fixing holes 41.
Referring to
Following that, referring to
When it is desired to detach the front and rear slide rails 1 and 2 from the slide rail posts 5, the user can do so by pulling the pulling surfaces 42 of the respective resilient engaging elements 4 outwards and detaching the retainers 43 from the slide rail posts 5, so that the front and rear slide rails 1 and 2 and the positioning elements 3 are disassembled from the slide rail posts 5. Thus, the slide rail device of the present invention can be rapidly assembled to and disassembled from an industrial computer or a host of related equipment without using any tools.
