Description

battery measuring device

technical field

The utility model relates to the field of battery maintenance, in particular to a battery measuring device.

Background technique

The structure of the power system test components is relatively complex, and the measurement is often carried out in a small space, and the positive and negative electrodes of the battery are covered with protective covers. The battery packs used in substations are mostly arranged in vertical layers. The length of the existing universal meter pens is mostly about 15cm. When measuring the voltage of a battery cell, it is extremely difficult for the meter pens to be inserted into the battery test hole. It is necessary to unscrew the positive and negative protective covers before testing. In the battery maintenance work, it is necessary to repeatedly open the protective cover-detection-cover the protective cover, so repeated, not only reduce the work efficiency, but also easily cause safety accidents due to accidental touch during the operation of opening-covering the protective cover. lead to low work efficiency. Moreover, when the positive and negative electric meter pens are held in one hand for measurement, a large angle will be formed between the electric meter leads, which will cause the measuring needle of the electric meter pen to tilt the measurement, and often cause poor contact and inaccurate measurement. In addition, if the positive and negative meter pens are held in both hands for measurement, the multimeter is inconvenient to place and read, which also affects work efficiency.

Utility model content

In order to solve the above problems, the utility model provides a storage battery measuring device which shortens the measuring time and is easy to carry.

The specific scheme of the utility model is: a storage battery measuring device, including a detachable insulating rod, the insulating rod is divided into insulating rod I and insulating rod II, and one end of the insulating rod I is fixedly connected with a meter pen I, and the other end is fixedly connected Insulation rod II, the lower part of the insulation rod is provided with a slideway, and the electric meter pen II is movably connected to the slideway, and the electric meter pen II and the electric meter pen I are respectively connected to the multimeter through their respective measuring lines.

A limit block is arranged on the outside of the part of the electricity measuring meter pen II located in the slideway, and a tightening device fixed by an insulating rod is arranged on the outside of a part outside the slideway.

The tightening device is a nut.

The insulating rod I and the insulating rod II are connected by clamping.

The insulating rod I and the insulating rod II are connected through sockets.

The measuring ends of meter pen Ⅰ and meter pen Ⅱ are on the same horizontal plane.

The beneficial effects of the utility model are: the electric meter pen I and the electric meter pen II are kept in parallel, without opening the positive and negative protection cover of the storage battery, the measuring device is held in one hand, and the electric meter pen is directly inserted into the positive and negative poles of the battery It only needs to hold the universal meter pen in one hand, and hold the multimeter in the other hand to observe the data to complete the measurement, saving measurement time. The utility model can adjust the distance at will, fully adapts to various measurement environments, and also solves the problem of large-scale measurement of batteries in a narrow space, improves work efficiency, and has simple structure, convenient use, low manufacturing cost, and has better popularization and Use foreground. The insulating rod is detachable, divided into insulating rod Ⅰ and insulating rod Ⅱ. When the measuring distance is short, it can be disassembled and used, and it is easy to carry.

detailed description

Example 1

As shown in Figure 1 and Figure 2, a battery measuring device includes a detachable insulating rod, the insulating rod is divided into insulating rod I1 and insulating rod II2, one end of the insulating rod I1 is fixedly connected with the meter pen I4, and the other end is clamped The insulating rod II2 is connected, and the end of the insulating rod II2 and the insulating rod I1 is provided with a matching clamping end 10 . The lower part of the insulating rod is provided with a slideway 3, and the slideway 3 is movably connected with the electric meter pen II5, and the electric meter pen II5 and the electric meter pen I4 are respectively connected with the multimeter 7 through respective measuring lines 8.

A limiting block 11 is arranged outside a part of the meter pen II 5 located in the slideway 3 , and the size of the limiting block 11 is larger than the edge width of the slideway 3 . A part outside the slideway 3 is provided with a tightening device 6, and the tightening device 6 is a nut. When the position of the electric meter pen II5 is determined, tighten the tightening device 6 toward the insulating rod, the limit block 11 and the tightening device 6 fix the electric meter pen II5 and the insulating rod together, so that the position of the electric meter pen II5 is fixed; When the electric meter pen Ⅱ5 is moving, loosen the nut away from the insulating rod, the electric meter pen Ⅱ5 is in a movable state, and then move the electric meter pen Ⅱ5 to an appropriate distance.

The measuring ends of meter pen Ⅰ4 and meter pen Ⅱ5 are on the same horizontal plane.

Example 2

As shown in Figure 3 and Figure 4, the difference between Embodiment 2 and Embodiment 1 is that: the insulating rod I1 and the insulating rod II2 are connected through a sleeve, and the end of the insulating rod II2 and the insulating rod I1 is fixedly connected with a sleeve 9 .

In the working mode, there is a slideway on the insulating rod. First, move the meter pen II according to the measured distance between the positive and negative poles of the battery, and then tighten the tightening device. The pen II is fixed without opening the positive and negative poles of the battery. With a protective cover, hold the measuring device in one hand, and insert the meter pen directly into the positive and negative test holes of the battery for testing, saving time. The insulating rod is detachable, divided into insulating rod Ⅰ and insulating rod Ⅱ, which can be disassembled for use. When the measurement distance is small, the meter pen II can slide to the insulating rod Ⅰ part through the slideway, and only use the insulating rod Ⅰ part Take measurements, easy to carry.
