BACKGROUND

Technical Field

The present disclosure generally relates to the field of industrial computer cabinets. More particularly, the present disclosure relates to an elastic clamping fastener module of an industrial cabinet rail which is convenient to assemble and can be fixed to both sides of a chassis in an elastic clamping manner during installation, so as to improve installation stability.

Description of Related Art

In general, an industrial computer is installed horizontally in an industrial cabinet, and a chassis is installed vertically to each of the four corners of the industrial cabinet, and a relative surface of each chassis has a plurality of fixing holes or screw holes formed vertically thereon and spaced from each other, and fixed by a fixing block or a fixing screw, so that the industrial computers can be stacked vertically in the industrial cabinet.

Since it is necessary to remove the industrial computers from the industrial cabinet for maintenance and repair, and this inconvenient method using the fixing block or fixing screw for the fixation takes much effort for the removal, therefore a pull-out type slide rail is provided to replace the traditional fixing block or fixing screw for installation. The pull-out type slide rail has the pull-stretching and stack-retracting features, and the slide rails of different lengths can overcome the issue of insufficient space by a two-stage or three-stage design and also can push the industrial computers into the industrial cabinet or pull the industrial computers selectively out from the industrial cabinet for expansion, replacement, inspection, or maintenance and repair, so as to improve the convenience of future maintenance. Traditionally, the fixing screw is used to fix the slide rail into the industrial cabinet, and the removal and reinstallation are very troublesome.

In recent years, various types of fixing fastener modules are introduced to overcome the problem of the convenient removal, and these fixing fastener modules are installed at both ends of the slide rail, and the fixing fastener module has a fixing pillar disposed on a surface of the fixing fastener module and passing into the fixing holes of the chassis, and the weight of the industrial computers can keep the slide rail to be fixed between the chassis, so as to omit complicated procedure for the installation or removal. In this pressing method by using the weight of the industrial computers, the industrial computers may have violent vibration or topple over. Therefore, the industrial computers may fall out or may even be damaged easily, and screws are added for auxiliary fixation to improve the installation stability. However, such arrangement results in an inconvenient removal.

In view of the aforementioned drawbacks of the prior art, manufacturers have designed and developed a fixing and engaging module with an automatic locking function in recent years, and provided a special hook design capable of locking the fixing and engaging module onto the chassis automatically after the installation without requiring additional screws for the fixation. In practical operations, the structural design of such fixing and engaging module has the issue of being loosened easily by wrong operations or misuses. Obviously, the conventional fixing and engaging module requires further improvements.
