Description
[technical field]
The utility model relates to a kind of expansion card fixer that is applied in the computer, refers to a kind of expansion card fixer of simple in structure and fast demountable especially.
[technical background]
The function limitation of PC, is installed some and is strengthened its extra function as expansion boards such as sound card, graphics acceleration cards for cooperating the more and more stronger functional requirement of computer now in the configuration of motherboard itself on the expansion slot of motherboard mostly.After expansion board is installed on the slot of computer motherboard, in the removable computer process or computer when being subjected to accidental shock, expansion board can produce and come off, also or the loosening slot that rocks motherboard of expansion board cause damage, for preventing that this kind from coming off or becoming flexible, need expansion board is firmly secured in the slot of motherboard.
Announce the 4th, 745 as United States Patent (USP), the expansion board fixed structure shown in No. 524 is to adopt a pressing structure, a screw, to transplant a cutting to cooperate expansion board is installed on the computer base.This pressing structure one end is buckled on the expansion board, and the other end is provided with the Extendible flake of a tool pickup groove, also has a pickup groove in this cutting, and this screw passes these pickup grooves this pressing structure is locked on the pedestal, thereby expansion board is fixed.Yet this kind expansion board fixed structure once can only be fixed an expansion board, and must use screw, causes expansion board fixedly efficiency of loading reduction and complex operation complexity.
United States Patent (USP) announces the 5th, 317 for another example, and the expansion board fixed structure shown in No. 483 is to adopt a press strip, a screw fit that a plurality of expansion boards are fixed on the computer base.What this press strip one end was movable is installed on this expansion board window-frame, and the other end is installed a screw, and this expansion board window-frame is provided with a screw to screw place that should press strip, suppresses the fixing of reaching expansion board on these are transplanted a cutting by this press strip.As United States Patent (USP) bulletin and the expansion board fixed structure shown in the 5th, 936, No. 835 is to adopt a pressing structure to cooperate with a plurality of cutting a plurality of expansion boards are fixed on the computer base.This pressing structure one end extends and a plurality of cutting is compressed on clamping structure on the expansion board holder, the other end is extended with a locking plate, this computer base is provided with a screw, and clamping structure is suppressed on transplanting a cutting, and it is fixing that locking plate utilizes screw locking promptly to reach on computer base.Above-mentioned two kinds of expansion board fixed structures all can once be fixed a plurality of expansion boards, twist admittedly but these structures all need to use screw, install and remove loaded down with trivial details inconvenience, reduce work efficiency.
[summary of the invention]
The utility model has overcome the low shortcoming of above-mentioned expansion card fixer efficiency of assembling, and a kind of expansion card fixer that need not the screw locking, once can fix a plurality of expansion boards and can assemble fast is provided.
Scheme of the present utility model is: this expansion card fixer comprises that one is provided with the back plate that expands deck, one be hubbed at this expansion deck compress device and by the clamping device that is loaded on these expansion deck both sides, establish one on this expansion deck in order to support the supporting wall of this expansion board catch, this clamping device is provided with a projection, when compressing device, this rotates to when compressing the position of this catch on this supporting wall, this projection compresses device with this and cooperates this is compressed device card and be fixed in this and compress the position, when this clamping device of operation,, this projection separates the catch that discharges this expansion board thereby compressing device with this.
The utility model expansion card fixer adopts the elasticity of material itself to fix mode, need not use the screw locking, and can once fix a plurality of expansion boards.Only need pull clamping device during dismounting and get final product, easy and simple to handle, can realize the quick assembling of expansion board.
