Summary of the invention
Technical assignment of the present invention provide a kind of simple in structure, volume is little, production cost is low, be easy to process, by the worm-and-wheel gear drivening rod press down the integrated circuit board briquetting to various expansion board clampings not of uniform size fix, universal expansion board clamping and pressing element easy to use.
Technical assignment of the present invention is realized in the following manner, comprises worm-and-wheel gear, connecting rod and integrated circuit board briquetting, and worm-and-wheel gear connects connecting rod one end, and the connecting rod other end connects the integrated circuit board briquetting, and the worm-and-wheel gear drivening rod presses down the integrated circuit board briquetting; Worm-and-wheel gear comprises pedestal, worm gear and worm screw, and worm screw is fixed on the pedestal, and worm gear is arranged on the pedestal by bearing, and worm gear and worm screw are matched, and connecting rod is inlayed and is fixed on the worm gear two sides.
Integrated circuit board briquetting bottom has rubber presser feet groove.
Worm-and-wheel gear drives and forces in connecting rod, is vertically compressed to the integrated circuit board briquetting by connecting rod.
Connecting rod adopts corrosion resistant plate to make, and pedestal adopts aluminium sheet to make.
Pedestal adopts the method for hot investment casting or die casting to process.
Worm gear is arranged on the pedestal by bearing, and bearing is two, separates from the center.
Worm screw bottom support axle adopts semicircle to support.
During use, the expansion slot top of each Designing of Reinforced Computer all adds a fixed strip, and fixed strip is fixed along the length direction of expansion board clamping.Continuous slotted hole is arranged in the fixed strip.Universal expansion board clamping and pressing element of the present invention is contained in the fixed strip bottom surface, is fixed with two major part screws.Move along the fixed strip slotted hole relevant position, up to correct position.Find correct position that the rubber presser feet notch of integrated circuit board briquetting is aimed at required fixing integrated circuit board top, find the relevant position, at this moment can slowly adjust the notch of top worm screw, clockwise turn to fasteningly, be rotated counterclockwise to unclamping with screwdriver.Adjustment slowly, feeling stressed can stop, and with the major part screw the present invention is fastened on the fixed strip to get final product.
Universal expansion board clamping and pressing element of the present invention is compared with prior art and is had the following advantages:
1, be applicable to compressing of all kinds of expansion cards (client's integrated circuit board etc.) that install additional in the expansion slot in the various ruggedized computers, its principle of work straightforward, the integrated rate of integral type is very high, and the scope of application is very wide to adapt to nearly all expansion card, manipulates more convenient;
2, volume is little and carry-over moment is big;
3, the peculiar function by worm-and-wheel gear becomes the direction of the rotation of manual levelling operation into direction for vertical rotation; The characteristics that increase moment by worm-and-wheel gear will enlarge tens times with screwdriver transmission strength by hand;
4, utilize the major part screw that the present invention is fastened on the fixed strip after compressing adjustment, also with worm screw locking, become flexible in the time of fastening so as to preventing;
5, reasonable in design, simple in structure, be easy to processing, easy to use, thereby, have good value for applications.
