Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of measurement, in particular to a measuring instrument for new energy equipment. BACKGROUND

[0002] The wiring terminal of the new energy battery is composed of a top stud, a gasket and a nut. A plurality of new energy batteries are placed in the battery box inside the vehicle. One end of the line is fixed to the wiring terminal (pole) of the new energy battery. The cover plate of the battery box is closed to seal the new energy battery. The new energy battery is used to power the vehicle to drive the vehicle. There is a certain safety gap between the cover plate and the wiring terminal of the new energy battery. Since the cover plate of the vehicle is often pressed during use, the safety gap of the vehicle needs to be strictly controlled. The distance between the cover plate and the wiring terminal of the new energy battery should have a gap of more than 30mm. If the cover plate and the live part are effectively insulated, the gap is at least 10mm. Similarly, according to the standards of the International Electrotechnical Commission (IEC), such as IEC61851, the safety gap between the high-voltage wiring terminal in the charging pile and the metal shell of the charging pile is usually clearly specified. Voltage level also needs to be considered because the safety distance is different under different voltages. For example, the voltage of direct current fast charging is high, which may require a larger gap.

[0003] The prior art has difficulty in measuring the gap because the tool cannot be inserted after the cover or shell is closed. It is difficult to effectively measure the gap distance. If there is an insulation layer, the flat insulation object is placed against the new energy battery box port, and the distance between the new energy battery electrode and the insulation object is measured with a steel ruler while wearing insulated gloves. The sum of the two data minus the overlapping part of the new energy battery cover and the new energy battery box is the data to be measured. The measurement process is difficult and troublesome, which reduces the work efficiency. Similarly, the distance between the high-voltage wiring terminal in the charging pile and the metal shell of the charging pile also encounters similar problems during measurement. The internal space is not visible after the shell is packaged, and common tools cannot effectively measure it.

[0004] Therefore, the present application provides a measuring instrument for conveniently measuring the gap between the wiring terminal of a new energy vehicle battery or a new energy charging pile and a metal part (cover plate or shell). SUMMARY

[0039] Working principle: in the initial state as Figure 1As shown, when the staff needs to measure the insulation distance of the new energy battery terminal, first hold the rotating head 23 and rotate it, so that the rotating head 23 drives the bidirectional screw rod 22 to rotate under the action of external force, the bidirectional screw rod 22 drives the two C-shaped rings 25 to move closer to each other or farther away from each other through the threaded action with the threaded tube 24, thereby adjusting the distance between the two C-shaped rings 25, then place the detection box 11 on the top of the new energy battery, and clamp the two C-shaped rings 25 on the outside of the two terminal nut of the new energy battery, so as to position the detection box 11;

[0040] Then the staff holds the pull ring 38 and moves it upwards, so that the pull ring 38 first moves out of the storage groove 37 under the action of external force, then drives the top plate 36 to move upwards, the top plate 36 drives one end of the telescopic plate 39 to move upwards through the hinged action, the telescopic plate 39 is elongated and rotated, at the same time, the top plate 36 drives one end of the two supporting plates 35 to move upwards, so that the supporting plates 35 drive the C-shaped plate 31 to slide along the inner side of the inverted T-shaped groove 12 through the hinged action of the other end, the two C-shaped plates 31 move towards each other, the C-shaped plate 31 drives the limiting column 34 to slide along the inner side of the limiting hole 13, when the limiting column 34 slides to the inner wall of one end of the limiting hole 13, the top plate 36 moves to the highest position, at the same time, the top plate 36 drives one end of the spring strip 42 to move upwards in the process of moving upwards, so that the spring strip 42 is gradually disassembled from the surface of the hollow column 41, when the top plate 36 moves to the highest position, the spring strip 42 is straightened, and the disassembly process of the spring strip 42 drives the hollow column 41 to rotate in the opposite direction, thereby driving the gear 43 to rotate through the hollow column 41, so that the gear 43 drives the measuring scale 44 to move from the inner side of the sliding hole 18 through the meshing action with the tooth groove 45, so that one side of the measuring scale 44 with the scale 46 is completely exposed to the outside;

[0041] The staff closes the cover plate of the new energy battery, so that the cover plate of the battery extrudes the top plate 36 downwards, in the process of moving downwards, the spring strip 42 drives the hollow column 41 to rotate in the positive direction under the action of its own elastic force, so that the measuring scale 44 gradually enters the inner side of the sliding hole 18, when the cover plate is completely closed, only a part of the measuring scale 44 is exposed to the outside, open the cover plate and check the measuring scale 44 exposed to the outside, at this time, the reading of the scale 46 is the insulation distance of the new energy battery;

[0042] When it is needed to measure again, move the measuring device to the position to be measured, only need to hold the two push plates 33 and move them towards each other, move the top plate 36 to the topmost position for resetting, and then measure again.

[0043] Similarly, when it is needed to measure the gap between the conductive terminal and the metal part of the new energy charging pile and the like, the above similar operation mode can be used for measurement.
