Lid fastening mechanism

Abstract

The present invention provides a lid fastening mechanism for fastening a lid of a device to a casing opening between two opposing flanks of the device. At least one side of the lid includes a lid flank overlapping an inner side of one of the flanks of the device. The lid flank is slidable to and fro relative to the flank of the device. The lid fastening mechanism includes a fastening post protrudingly disposed on the inner side of the flank of the device, a movement groove disposed at a position of the lid flank corresponding to the fastening post, and a snap fastener disposed to extend along an inner side of the lid flank and formed with a snap hole for snap-fit engagement with the fastening post. The fastening post can slide into the snap hole via the movement groove and thereby fasten the lid to the casing opening.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a fastening mechanism, and more particularly, to a lid fastening mechanism for an electronic device.[0003]2. Description of the Prior Art[0004]Owing to the rapid development of the electronic industry, server products are becoming easier to maintain and easier to assemble. To meet the demand for easy maintenance and assembly of server products, the requirement for auxiliary structures designed to facilitate the assembly of server products gradually shifts from long working hours to short working hours, to increase productivity per unit working hour by improvement in casing assembly technology.[0005]Conventional structures of the casings for servers are available on the market nowadays. To enhance the precision of assembly of servers, the manufacturers developed a screw fastening technology that involves forming a screw-fastening auxiliary structure at the edge of a covering lid of a casi...

AI Technical Summary

Benefits of technology

The present invention provides a lid fastening mechanism for electronic devices that allows for easy mounting and unmounting without the need for tools. The mechanism includes a fastening post, a movement groove, and a snap fastener. The fastening post is protrudingly disposed on the inner side of the device's flank and the movement groove is positioned at the lid flank. The snap fastener is formed with a snap hole that snaps into the fastening post to secure the lid to the device's casing opening. The mechanism allows for quick and easy mounting and unmounting of the lid and is highly industrial applicable.

Problems solved by technology

As mentioned above, conventional structures of the casings for servers comprise the screw-fastening auxiliary structure formed in the casing for a server and designed to enhance the precision of assembly of servers, thus resulting in complicated structures and long assembly working hours.

Besides, the screws as such increase the number of components to be assembled, which in turn increase the number of the assembly steps, thus making assembly work more difficult and complex; hence, it is hard to meet the requirement for the working hours of sever assembly.

As a result, the necessity of performing a screw-related process on a conventional server casing structure leads to a complicated fabrication process, high assembly cost, expensive manpower invested in the fabrication process, lengthy assembly process, and slow maintenance.

In addition, in the course of a manual assembly process, both variation in the degree of workers' skills and discrepancies in technologies cause reliability-related problems and affect the precision of working hours, thus affecting the timing of the process greatly.

As regards the technology of fastening a lid to the front of a server, in the old days the lid was secured in position with blind rivets and thus the server could not be dismantled of the lid thereafter.

Nevertheless, screw locking does have its own drawbacks, namely a complicated, time-consuming mounting / unmounting process, and indispensable use of tools.

Accordingly, an issue calling for urgent solution is to overcome the aforesaid drawbacks of the prior art effectively.
