Description

Buckle linkage structure

The present invention relates to a snap linkage structure, in particular to a hidden design of a handle linkage buckle, which is suitable for application on various replaceable modules in a server host, and can be applied to a fixed structure inside the module. The external chassis is buckled, and the interlocking structure is used to achieve a 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. Under the prior art, there is no problem with the method of the prior art, but the size of the mainframe casing is increasingly reduced. Therefore, the use of the method of the prior art to design the replaceable module has the problem that the module is too large. 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, but it must also have a fixture for the fixed module or Structure, while the prior art has a larger module size because the fixed structure is designed on the module. 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 of the scope of the present invention is to provide a snap-and-lock structure suitable for application to various replaceable modules within a server mainframe to solve the problems of the prior art.

The present invention provides a snap linkage structure for clamping a replaceable module to a casing. The buckle linkage structure is installed inside the replaceable module and includes a handle, a buckle component and a spring, and is suitable for being applied to various replaceable modules in the server host or the general host, such as: Replaced hard disk modules, fan modules, and power modules.

The snap linkage structure provided by the present invention replaces the prior art design in which the fixed structure is disposed outside the module by placing the fixed structure inside the module. In use, the hook inside the module protrudes out of the module and engages with the casing, thereby fixing the module. Another feature of the present invention is that by combining the handles and the snap elements respectively provided in the prior art, the hooks of the snap elements can be selectively withdrawn from the locking holes on the casing when the handle is rotated. And release the module, which has the effect of being convenient to use. After the module is released, the user can extract the replaceable module for replacement or maintenance. It is important to note that this creation protects the design spirit of the handle interlocking hook, so the handle and the snap element and the spring are not limited to one. Sometimes, for more stable fixing, it can also be designed to control one card with two handles. buckle Components, or one handle to control two snap elements, are within the scope of this creation.

When the creation is applied to the replaceable module in the chassis, the user only needs to press the handle down, and the interlocking design of the handle and the buckle component can be used to retract the hook and withdraw from the casing, thereby releasing The replaceable module. When the user stops pressing the handle, the spring can hold the snap element to return the hook to a state outside the replaceable module. In practical applications, the force-reducing handle can be pulled out and the externally applied force can be used to extract the replaceable module. When the replaceable module is installed, the removable module can be placed in an appropriate position and then applied. It can be pushed in. 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.
