Description

Tool-free server fixing device

This creation is used in the field of industrial computer cabinets, especially a tool-less server fixing device that facilitates the rapid assembly of the chassis on the slide rails to improve the intuitiveness and convenience of operation.

According to the current common industrial computer cabinets, there are many rack servers inside, which are installed on both sides of the computer cabinet by using slide rails. Most of the slide rails and their brackets are erected on the computer The cabinet is read on the pillar, so that the server can be directly pulled out to the outside of the computer cabinet for inspection and maintenance.

US Patent No. 6,209,979 relates to a slide rail assembly with a quick installation system, which utilizes the top of the slide rail to directly cut out a plurality of L-shaped holes, and the sides of the chassis are provided with a plurality of hanging posts through which the hanging posts are embedded in the Positioning in the mounting holes of the slide rail, and blocking one of the plurality of mounting holes by means of a stopper to quickly install the chassis on the slide rail. Also belonging to such installation design methods are the cases of US patents U.S. 6,601,933, U.S. 6,938,967 and U.S. 7,382,623.

However, generally speaking, due to the limited space for placing computer cabinets, it is sometimes difficult to obtain an effective space for vertical placement operations, and at the same time, the block must be operated to release the lock, which greatly affects the convenience during operation. In addition, the L-shaped holes provided in this type of slide rail are arranged from the top to the center of the slide rail, and the cross-sectional area of the rail body at the L-shaped hole is relatively reduced, thus resulting in sliding The structural strength of the rail itself is reduced and affects the load capacity of the installed chassis. In addition, since these computer cabinets already have common specifications, their size and pillar spacing have certain regulations. If the server chassis volume needs to be increased, the thickness of the slide rail will be relatively thin, so the thinner sliding The structural strength of the rail is tested, and it is a rather unfavorable design for the strength of the slide rail with the aforementioned L-shaped hole design. In addition, based on the thin design of the slide rail, the space between the rails is narrower and narrower. If the design of the stopper is too complicated or the number of components is large, it is not only difficult to operate, but also results in a waste of space. .

However, in another common installation method, a fixing bolt is provided on each side of the chassis, and a keyhole slot-shaped groove is provided on one of the rails of the slide rail and fixed by means of an elastic sheet The rail corresponds to the key hole, wherein the key hole includes an enlarged hole and a narrow hole communicating with the enlarged hole, and the elastic piece is a design that extends the sheet body to the key hole to cover the enlarged hole. When assembling, the fixing bolt is used to penetrate into the key hole of the rail, and the fixing bolt is inserted into the enlarged hole of the slot and then displaced toward the narrow hole of the slot, and the elastic piece is pressed against the slot The bolt is fixed to form a latch. Such as: US Patent No. 7,604,307 "telescoping slide assembly with quick-mount keyhole lock system" and US Patent No. 6,626,300 "rack assembly that does not require tools for coupling chassis to slide" are representatives of using this kind of similar technology patent.

However, this type of installation method often causes the fixing bolt and the shrapnel to collide with each other due to the pulling of the slide rail or the vibration of the use environment, or to continuously push the shrapnel during disassembly. If the design of the shrapnel is insufficient to withstand its impact and When the force is pushed, the shrapnel is likely to be deformed or broken, which leads to the failure of the fixing effect of its installation and needs to be improved.

In view of this, the author has been continuously researching, improving and testing, designing a tool-free server fixing device, using the separation of the parts that provide the fixing effect and the elastic effect when returning to the original state, not only can effectively reduce the parts The quantity, without the need for additional structure, will not cause trouble for processing and manufacturing; and, the operation is also quite intuitive and smooth, which greatly improves the convenience of operation.

In view of this, one of the purposes of this creation is to provide a tool-free server fixing device that uses a specially designed fixed spring clip to be fixed on an inner rail for the latch to be fixed on a pair of chassis outside the chassis The rivets form a multi-point fixation, which greatly improves their stability. Furthermore, because the fixed elastic piece is used to fix the inner rail and the elastic part that provides the resilience is designed separately, it will not be easily broken and damaged due to operation. Moreover, the manufacturing cost can be reduced without additional processing, and the operation of disassembling and assembling is also quite intuitive and smooth, which greatly improves the convenience of operation and other functions.

In order to achieve the above-mentioned purpose, the tool-less server fixing device of the present creation includes a server case and the case is fixed on an inner rail.
