Screw connects a type printed circuit board locking device, and is because screw rod has occupied certain space, bigger to the screw specification influence that connects printed board.
It is complicated that riveted joint connects type riveting process of printed circuit board locking device, riveted joint back dismounting difficulty, and recycling rate of waterused is low.
Summary of the invention
Goal of the invention of the present invention is to overcome the deficiency of existing printed circuit board locking device, provides a kind of simple in structure, is easy to processing, and processing cost is low; In light weight, heat-conductivity conducting is effective, and Safety performance is good; Highly versatile is convenient to dismounting, the printed board locking device that reuse is strong.
Goal of the invention of the present invention realizes through following technological scheme: a kind of printed board locking device; It comprises top slide block, slide block, slide rail, following fixed block, captive screw and sunk screw, and an end of slide rail is fixed on down on the fixed block through countersunk head semi-tubular rivet.Top slide block, slide block are arranged in the chute of slide rail and can on slide rail, move; Captive screw passes top slide block, is installed in the screw of slide rail one end; Sunk screw is positioned at the captive screw lower end, is installed on the slide rail.
Captive screw of the present invention is provided with plain washer and spring washer.
Slide block of the present invention is trapezoidal, and gradient is consistent with the gradient of top slide block and following fixed block, and is less near the base of slide rail.
Also be provided with tapped hole on the slide rail of the present invention.
The helical thread portion diameter of captive screw of the present invention is greater than the diameter of screw rod.
The screw rod sliding contact of sunk screw of the present invention and captive screw.
The invention has the beneficial effects as follows: provide a kind of simple in structure, be easy to processing, processing cost is low, and is in light weight, and heat-conductivity conducting is effective, and Safety performance is good, and highly versatile is convenient to dismounting, the printed board locking device that reuse is strong.

Embodiment
Below in conjunction with accompanying drawing further explain technological scheme of the present invention: like Fig. 1; Shown in Figure 2; A kind of printed board locking device; It comprises top slide block 1, slide block 2, slide rail 3, fixed block 4, captive screw 5 and sunk screw 9 down, and the material of top slide block 1, slide block 2, slide rail 3 and following fixed block 4 all adopts aluminum alloy 6063 to push the section bar that forms, in light weight, heat conduction, the advantage that conductive effect is good, processing cost is low.Captive screw 5 is installed in the screw of slide rail 3 one ends after passing top slide block 1, and captive screw 5 is provided with plain washer 7 and spring washer 6 simultaneously.Worm's eye view such as Figure 10 of following fixed block 4 are said, the ramp structure coupling of the ramp structure of following fixed block 4 and slide block 2, and the worm's eye view of top slide block 1 is as shown in Figure 7; Top slide block 1 is located in the chute of slide rail 3 and can on slide rail 3, moves, and slide block 2 is trapezoidal, and gradient is consistent with the gradient of top slide block 1 and following fixed block 4; Its base near slide rail 3 is less, and slide block 2 worm's eye views and side view be respectively like Fig. 8 and shown in Figure 9, the structure matching of slide block 2 and slide rail 3; Make slide block 2 on slide rail 3, to slide flexibly, sunk screw 9 is positioned at captive screw 5 lower ends, and specification is M1.6x3; The screw rod sliding contact of it and captive screw 5; But helical thread portion then can not pass through, and this has just ensured that captive screw 5 does not come off, the faults of avoiding captive screw 5 to come off causing such as device short circuit, damage such as printed board.。
As shown in Figure 3, slide rail 3 is provided with tapped hole 10 and attachment screw 11, and the specification of tapped hole is M2 or M2.5, and maximum effective thread screwing length is 6mm, and when being connected with printed circuit board, convenient disassembly, reuse are strong.
As shown in Figure 4; Subrack 12 should be printed board 13 grades that locking device is housed a guide securement slot is provided; The width sum that the width of slot should be printed board 13 and heat conduction filler strip 14 adds 8 to 9 millimeters; Just can reach extruding top slide block 1 through regulating captive screw 5, thereby make slide block 2 protrude the purpose of extruding locking printed circuit board 13.
Like Fig. 5; The head of captive screw 5 is provided with groove, and groove is yi word pattern or interior hexangle type commonly used, and the screw length of captive screw 5 is 20～21mm; Effective thread is 5～6mm; Screw polished rod section diameter is 1.6～1.8mm, and less than the diameter of its helical thread portion, material is generally stainless steel.
Countersunk head semi-tubular rivet 8 materials as shown in Figure 6 are stainless steel 1Cr18Ni9Ti, adopt the technology of disposable bloated riveting to be fixed on slide rail 3 and the following fixed block 4, and are simple in structure, durable, processing cost is low.
