Description

The motherboard fixture

[technical field]

The utility model is about a kind of motherboard fixture, be meant especially a kind of simple in structure, can reach the installation of motherboard in electronic equipment and the motherboard fixture of dismounting quickly and easily.

[background technology]

The motherboard carrier of general computer chassis is one-body molded with the computer chassis pedestal, and motherboard then is installed on this carrier.During assembling, motherboard usually must pass through a plurality of screw lockings on this carrier, so assembling process is loaded down with trivial details, and speed is slow, also can make the whole piece assembly line stop the line stopping production because certain single link goes wrong, thus the production efficiency of having a strong impact on.

In addition, when the assembly of changing or keeping in repair on the motherboard, because spatial limitation in the computer chassis, if motherboard is not taken out in computer chassis, not only operation inconvenience also damages other assembly in the computer easily, and in these structures, shift out if this motherboard need be pulled down, need these screws are pulled down one by one, greatly the convenience of influence operation by instrument.

So, industry proposes motherboard carrier and computer chassis base-separation, make motherboard be assembled to carrier in advance, again this carrier is assembled to the scheme of computer chassis pedestal, promptly simplify the convenience of production line, lifting packaging efficiency, increase assembly and disassembly by modular mode.Simultaneously, also, further simplify motherboard assembly and disassembly process constantly towards the R﹠D direction development that reduces the screw usage quantity.

Installation and the remove mode of this type of removable formula motherboard carrier in computer can be with reference to No. the 95214761.0th, Chinese patent, the motherboard carrier of its announcement is to reach its dismounting on computer chassis in the Spring lock catch mode, yet, the complex structure of this Spring lock catch device, it is a lot of to form assembly, not only the effect of being reached is limited, also increases the manufacturing cost of product simultaneously.And for example No. the 00201452.1st, Chinese patent, the structure of its announcement is, on the board of computer chassis, be provided with convex body to upper process, the convex body center of top is offered a screw, motherboard is placed on this convex body, the fixing hole of motherboard is relative with screw, by screw motherboard is fixed in the computer chassis, and the use of its many screws makes the assembly and disassembly of motherboard loaded down with trivial details.

In addition, general removable formula motherboard carrier is when dismounting, and its many directions towards operator's application of force move release, if the space of this direction is limited, then very easily damages other assembly that is fixed on this direction, has greatly reduced the convenience of dismounting.

[summary of the invention]

Technical problem to be solved in the utility model be to provide a kind of simple in structure, can realize quickly and easily installing in motherboard is on electronic equipment and the motherboard fixture of dismounting.

The utility model solves the problems of the technologies described above by the following technical programs: the utility model motherboard fixture, be used for the motherboard of the some installing holes of a tool is fixed in the electronic equipment, this motherboard fixture comprises a carrier, an operating parts, a base plate and a pair of fixing body that is fixed in this base plate.This carrier is fixed on the bottom of this motherboard, and this operating parts can be around this carrier rotation, and this operating parts comprises two plumbing arms, and a draw-in groove is offered in each plumbing arm lower end, offers some installing holes on this carrier.This base plate is convexly equipped with some grabs corresponding to the position of mounting hole of this motherboard and this carrier.The installing hole of this motherboard and this carrier can be distinguished the grab of this base plate of sheathed correspondence during installation, the draw-in groove of this operating parts is striden and is located at this fixing body, by rotating this operating parts, can be with the fixing and demolition on this base plate that are combined in of this carrier and this motherboard.

The advantage of the utility model motherboard fixture is: the utility model motherboard fixture is when the dismounting motherboard, only need to be fixed on operating parts on the carrier by start one, the assembly of realizing this motherboard and carrier moves on the direction of motion perpendicular to this operating parts, realize dismantling this motherboard, thereby avoid spatial limitation on this motherboard direction of motion from this base plate.
