Description

High-adaptability mutual inductor on site verification wire clamp

Technical field

The utility model relates to a kind of on-the-spot mutual-inductor calibration device.

Background technology

The wire clamp that existing on-the-spot mutual-inductor tester is used for connecting mutual inductor and p-wire is spring crocodile clip.This kind of wire clamp drives crocodile tooth interlock mutual inductor terminal by spring force, realizes being connected of p-wire and mutual inductor.Yet field condition is changeable, mutual inductor terminal nut is not of uniform size, and this kind of wire clamp can not guarantee snap-in force; On-the-spot mutual inductor secondary terminals is often arranged in the groove of narrow space, and crocodile clip is because volume cannot insert more greatly, and on-the-spot adaptability is lower.

Summary of the invention

The problems referred to above that exist for solving existing verification wire clamp, the utility model provides a kind of high-adaptability mutual inductor on site verification wire clamp, and its technical scheme of taking is:

Comprise upper left clamping plate, upper right clamping plate, lower plate, pressing plate, sliding band and runner frame, upper left clamping plate, upper right clamping plate and lower plate horizontally set, the left end of the right-hand member of upper left clamping plate and upper right clamping plate is hinged by rotating shaft I, in rotating shaft I, cover has the torsion spring I that can tighten counterclockwise, one end of torsion spring I is fixed on the clamping plate of upper left, its other end is fixed on the clamping plate of upper right, runner frame is fixed on the bottom surface of lower plate, the bottom of pressing plate and the both sides of runner frame are hinged by rotating shaft II, in rotating shaft II, cover has the torsion spring II that can outwards tighten, one end of torsion spring II is fixed on pressing plate, its other end is fixed on runner frame, sliding band is vertical to be arranged, even rectangular leg-of-mutton sawtooth on the front side zone face of sliding band, the hypotenuse front end updip of each sawtooth, the upper end of sliding band is fixed on the bottom of upper left clamping plate, its lower end is successively through lower plate and runner frame, the front end-plate face processus aboralis of pressing plate and may be stuck on arbitrary sawtooth, the bottom of pressing plate is provided with shifting block.

The utility model is used sliding band, pressing plate to coordinate with runner frame, improve the adaptability of wire clamp to different-diameter mutual inductor terminal, by using the torsion spring at rotating shaft two places to coordinate sliding band to make up the defect that it cannot be smoothly mobile, guaranteeing under the prerequisite of snap-in force, the wire clamp design proposal that can adapt to most of field conditions, has improved adaptability and the operability of on-the-spot transducer check.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

As depicted in figs. 1 and 2, upper left clamping plate 1, upper right clamping plate 2 and lower plate 3 horizontally sets, the left end of the right-hand member of upper left clamping plate 1 and upper right clamping plate 2 is hinged by rotating shaft I 7, in rotating shaft I 7, cover has the torsion spring I that can tighten counterclockwise, one end of torsion spring I is fixed on upper left clamping plate 1, its other end is fixed on upper right clamping plate 2, runner frame 6 is fixed on the bottom surface of lower plate 3, the both sides of the bottom of pressing plate 4 and runner frame 6 are hinged by rotating shaft II 8, in rotating shaft II 8, cover has the torsion spring II that can outwards tighten, one end of torsion spring II is fixed on pressing plate 4, its other end is fixed on runner frame 6, slide and be with 5 vertically to arrange, sliding with even rectangular leg-of-mutton sawtooth 9 on 5 front side zone face, the hypotenuse front end updip of each sawtooth 9, the sliding bottom that is fixed on upper left clamping plate 1 with 5 upper end, its lower end difference is lower plate 3 and runner frame 6 successively, the front end-plate face processus aboralis of pressing plate 4 and may be stuck on arbitrary sawtooth 9, the bottom of pressing plate 4 is provided with shifting block 10.

When field-checking mutual inductor, a side of upper right clamping plate 2 being close to mutual inductor terminal, then lower plate 3 is upwards promoted, when upper and lower clamping plate close up gradually, slide and be with 5 constantly to stretch into runner frame 6, the sliding hypotenuse with the sawtooth 9 on 5 promotes pressing plate 4 and outwards rotates, once but some sawtooth 9 pass through pressing plate 4, due to the effect of rotating shaft II 8 place's torsion springs, pressing plate 4 inwardly rotates, and blocking the right angle minor face of sawtooth 9, anti-Anti-slip belt 5 oppositely moves with upper right clamping plate 2.When stirring shifting block 10, pressing plate outwards moves, and separates with sawtooth 9, and upper right clamping plate 2 can separate with lower plate 3.Go up like this in lower plate course of action and remain parallel relation, guaranteed and the contacting of mutual inductor terminal.Torsion spring I in rotating shaft I 7 has given upper right clamping plate 2 one clockwise power, make to be with 5 cannot be pushed to next sawtooth 9 when sliding, but while still having space between upper left clamping plate 1, lower plate 3 and mutual inductor terminal, by upper right clamping plate 2, lower plate 3 and the tight occlusal contact condition of mutual inductor terminal, thereby made up the defect that sliding band cannot be smoothly mobile, improved adaptability.After verification completes, with hand, stir shifting block 10, lower plate 3 is promoted to the direction away from upper right clamping plate 2, can take off mutual inductor terminal.
