Description

The computer side board fixer

[technical field]

The utility model is about a kind of computer side board fixer, particularly about a kind of dismounting of being convenient to side plate, and easy to operate computer side board fixer.

[technical background]

The fixed form of existing computer side plate has multiple, and the most frequently used is directly with screw the computer side plate to be fixed on the pedestal.But this fixed form must be used instruments such as turnscrew, the very loaded down with trivial details inconvenience of process in the assembly and disassembly process of computer side plate.

Continuous progress along with computer technology, the assembly and disassembly of computer side plate for convenience, some improved computer side board fixers have also appearred in industry, as No. the 386613rd, Taiwan patent announcement, wherein this computer skeleton has a back plate face and a front face, the dual-side of this back plate face is established some grooves of wearing respectively, and the both sides of this front face are respectively equipped with some screws and can be spirally connected for some bolts.The computer side plate one medial margin backfin on one the first from left right side goes out a flanging, and this flanging extends some recessed grabs respectively, and opposite side edge backfin L type flap is established some perforation respectively on L type flap.Wherein this grab is movable inserts the wearing in the groove of back plate dual-side, and some bolt devices screw in the perforation of corresponding L type flap in the screw at front face again.Thereby this computer side plate is fixed on this computer skeleton.But the method for this fixedly computer side plate also must use turnscrew and twist solid screw or dismounting when side plate is installed and removed, and its assembling process is still more loaded down with trivial details time-consuming.

[summary of the invention]

The purpose of this utility model is to provide a kind of dismounting of being convenient to side plate, and easy to operate computer side board fixer.

Technical problem to be solved in the utility model is achieved through the following technical solutions: the utility model computer side board fixer comprises a pedestal, side plate and a clamping device.This pedestal has a back plate, and this back plate bends a flanging at the one lateral margin.This clamping device comprises that one is fixed on body, on this side plate and is slidingly installed with slide mass, on this body and is hubbed on operating body and on this body and is installed in spring between this body and this slide mass.This slide mass comprises the portion of sliding and a pressing portion, and this portion of sliding establishes a cross-notching.On this operating body fluting that should slide mass is convexly equipped with a pair of protuberance.When this side plate is installed, can pull this operating body, this protuberance is replaced this fluting edge and this slide mass is slided on this body and is compressed this spring, unclamps this operating portion then, make the pressing portion of this slide mass replace flanging by resetting of this spring, thereby fix this side plate at this back plate.

The utility model computer side board fixer also can be reached the spinning reduction of this operating body by a torque spring that is located between this operating body and body, and makes the pressing portion of this slide mass replace flanging at this back plate, thereby realizes the fixing of this side plate.

Effect of the present utility model is that the rotation by an operating body makes protuberance on it promote a slide mass and slides on a body, thereby makes the flanging of the pressing portion of this slide mass and a back plate replace or break away from, and realizes the fixing and dismounting of this side plate.
