The present invention addresses the above problem adopted technical scheme: the thread tensioning mechanism that is applied to the difficult skew of power domain, comprise stringing body, T shape screw rod, pressing plate, foam-rubber cushion and raised line, described stringing body arranges U-lag on side, groove is also set on U-lag inwall, in the bottom of U-lag, a raised line is also set, on the upper surface of stringing body, also crosses straight down caging bolt; Described T shape screw rod is vertically positioned at U-lag through stringing body and one end, and the bottom, one end that T shape screw rod is positioned at U-lag also connects pressing plate; Pressing plate, over against groove, all arranges foam-rubber cushion on the bottom of pressing plate and the U-lag inwall below pressing plate, and square groove is also set on side adjacent at the bottom of pressing plate and U-lag, and square groove is stuck on raised line.
Being used in conjunction with of raised line and square groove can only be slided pressing plate one side on raised line, avoids that pressing plate is irregular to be rocked, and damages parts, more convenient operation.On U-lag inwall below square pressing plate and below pressing plate, foam-rubber cushion is all set, can avoids square pressing plate and the sharp-pointed corner angle that are positioned on the U-shaped groove of square pressing plate below scratch mutual inductor, protected and needed the intact of fastening mutual inductor.
During use, only need rotate T shape screw rod, make to form gap between pressing plate and U-lag, then the fastening parts of needs are inserted in gap, now rotating tommyhead bolt makes pressing plate can realize fastening with needing secure component compression again, in rotation process, one end of pressing plate remains on raised line and slidably reciprocates always, avoids its amplitude of fluctuation excessive, damage parts, the serviceable life of improving this device.When not needing again when fastening, only need to rotate tommyhead bolt, make pressing plate separated with needs secure component, and do not need to change original shape of parts to be tightened, guaranteed the intact of parts to be tightened.For the fastening parts of columniform needs, can be positioned at the groove on U-lag inwall, avoid its landing, facilitate fastening.On stringing body, also cross caging bolt, when needs are used a plurality of this device, caging bolt can keep there is certain distance between two parts, conveniently takes out or is pressed into.
Described square groove can slidably reciprocate on raised line, and raised line is perpendicular to pressing plate.Facilitate square to block raised line and move back and forth.
The length of described raised line and U-lag bottom equal in length.Guarantee that pressing plate can move up and down in whole U-lag, conveniently press the parts of different-thickness.
Described T shape screw rod can rotate, and band dynamic pressure plate moves up and down in U-lag.Convenient will object compression be pressed or unclamp.
Described pressing plate is regular square steel plate, and the lateral surface of pressing plate flushes with the U-lag openend of stringing body.Pressing plate bottom is level and smooth, thing to be pressed can better be compressed, and not damage object to be pressed, easy to use.
The equal coupling nut in described caging bolt two ends.Make some evagination of turnbuckle both sides, facilitate turnbuckle and external agency to be separated out a segment distance, better realize and unclamping and fixing operation.
To sum up, the invention has the beneficial effects as follows:
1, the present invention is simple in structure, and processing ease is provided with special foam-rubber cushion, avoids fixedly, and device to be tightened directly contacts with U-lag with pressing plate, avoids the corner angle scratch device to be tightened on pressing plate and U-lag, has guaranteed the intact of device to be tightened.
2, the side at pressing plate arranges square groove, in the bottom of U-lag, the raised line mating with square groove is also set, and restriction pressing plate one side can only slidably reciprocate on raised line, avoids pressing plate whipping torsional amplitude excessive, damages parts, improves serviceable life.
3, the equal coupling nut in caging bolt two ends, makes some evagination of turnbuckle both sides, facilitates turnbuckle and external agency to be separated out a segment distance, better realizes and unclamping and fixing operation.
