Need to develop a kind of voltage check device for facilitating one-handed performance, can meet measurement action is repeated several times, it is easy, steady The open-circuit voltage values of the fixed various battery sizes of acquisition, lower cost of labor, improve operating efficiency, while improve the safety used Property.

Utility model content

The utility model is in view of the shortcomings of the prior art, there is provided a kind of one-hand operation, the detection lead of convenient use The device of battery open-circuit voltage.

A kind of device for detecting lead accumulator open-circuit voltage, including cross bar and two detectors, the detector pass through extension Hook is arranged on cross bar, and the hook is slidably matched with cross bar, and is bolted.During detection, two detectors connect respectively Touch the positive and negative electrode of lead accumulator, be connected with wire on detector, the other end connection universal meter of wire or it is similar can be with Detect the device of voltage., can be by unscrewing the position of moveable hook after bolt when needing to adjust the spacing between two detectors Put to adjust, can only adjust the position of one of them, or two are adjusted simultaneously.

Preferably, the cross bar is angle steel.

It is furthermore preferred that the top of the hook is inverted U, and reclined cooperation with two sides of angle steel.Hook is hung over After on cross bar, two sides of top U-shape structure part and angle steel recline cooperation, and bolt withstands angle steel from side and is fixed.

Preferably, the bottom of the hook is provided with the mounting hole with detector interference fit.

It is furthermore preferred that the insulating part that the detector includes the conductive contact on top and coordinated with mounting hole.Generally The preferable conductive effect of acquisition, conductive contact make to be made of copper.And the setting of insulating part, prevent short circuit.

It is further preferred that the insulating part is provided with lead placement hole, the lead placement hole is through hole, end and conduction Contact is interference fitted.

Preferably, the cross bar is provided with handle.Operated in use, handle can be held, it is more convenient.

Preferably, the cross bar is provided with the cable clamping interface for being used for fixing wire.After wire is drawn from detector, it can block In cable clamping interface, keep wire more neat not chaotic.

It is furthermore preferred that the cross bar has been bolted fixture block, the fixture block is divided into two parts, and a part reclines horizontal stroke Bar, there is gap between another part and cross bar, the gap forms described cable clamping interface.

Two detectors are arranged on cross bar by the utility model device by hook, even if battery positive and negative electrode is apart When larger, a hand operation is also only needed, it is not necessary to which during as using universal meter, two hands respectively hold " a table Pen ", lower cost of labor, improve operating efficiency, while improve the security used.And the spacing between two detectors can be with It is adjusted by linking up with the sliding position on cross bar, it is applied widely suitable for the lead accumulator of various models.
