Description

Inner hook structure

This creation is related to an inner hook, especially a hook design applied inside the module, which is suitable for application on various replaceable modules in the server host, and can be applied to the internal hook design of the module. To buckle the external chassis and use the linkage structure to achieve labor-saving effect, which can improve the size of the module in the prior art and the insufficient space inside the chassis.

In recent years, the computer industry has developed rapidly. Almost every small family has more than one home computer host. In response to the advent of the cloud era, the data center is expanding at a high speed, regardless of whether it is a large host computer for home consoles or large companies. Or the server host of the data center, in order to facilitate assembly and easy disassembly and assembly for maintenance or replacement, the various devices in the host are often designed as replaceable modules, such as: replaceable fan modules, hard drives Modules and power modules.

Most of the replaceable modules in the prior art use the fixing mechanism made on the outer casing of the module to lock/hook the additional firmware to achieve the purpose of fixing the module, and the space in the casing is sufficient. Next, there is no problem with this prior art method. However, due to the shrinking size of the mainframe casing, the use of the prior art method to design the replaceable module has the problem of excessive module size. In short, when the space inside the mainframe is limited by design or processing constraints, it is necessary to reduce the space for the module, and the prior art designs the fixed structure in the mold. This will cause the module to be bulky. Or, when the space in the module needs to place more components as much as possible without space to design the fixed structure, there is no design in the prior art that satisfies this requirement. In addition, in the prior art, the handle and the hook of the module are individually independent designs, which is not only inconvenient to use but also causes waste of space. In summary, the prior art does not provide a design that is convenient to use and that can effectively utilize the volume of the replaceable module as much as possible.

One aspect of the present invention is to provide an inside hook that is adapted to be applied to various replaceable modules within a server host to solve the problems of the prior art.

The present invention provides an inner hook structure for fastening a replaceable module to a casing. The inner hook is installed inside the replaceable module and includes a hook member and a handle member, and is suitable for being applied to various replaceable modules in the server host or the general host, such as: Hard disk module, fan module and power module.

The inner hook structure provided by the present invention replaces the prior art design in which the fixed structure is disposed outside the module by arranging the fixed structure inside the module. In use, the hook inside the module protrudes out of the module and fits into a fastening hole in the casing, thereby fixing the module. Another feature of the present invention is that by combining the handles and hooks respectively provided in the prior art, when the handle is pulled, the hooks can be selectively withdrawn from the locking holes on the casing, thereby releasing the mold. Group, with easy to use effect. After the module is released, the user can extract the replaceable module for replacement or maintenance. It should be noted that the hook opening on the top cover of the module, the fixing hole on the casing and the hook are not limited to one. Sometimes, for more stable fixing, the hook is opened and stuck. The holes and the hooks can be designed to be two or more.

In addition, when the creation is applied to the replaceable module in the chassis, the casing for securing the replaceable module in the chassis has a handle hole with respect to the handle opening of the upper cover of the module, the handle hole The area is smaller than the area of the opening of the handle, so that when the handle is pulled, it will bear against the edge of the handle hole (reflexed flat), and the lever principle is used to save the laborable release module. The focus of this creation is on the hidden design of the fixed structure inside the module. Therefore, the external part of the module does not need to be designed with a fixed structure, so that the volume of the module can be optimally utilized, so the space inside the casing is limited. In the case of the case, or when the external design space of the module is insufficient, the design of the creation can still be used to fix and replace the module.

The advantages and spirit of this creation can be further understood by the following detailed description of the creation and the drawings.
