[0002] During the inspection or maintenance of air conditioners (or other similar equipment), staff will check whether the power supply voltage is normal. The installation position of air conditioners (including outdoor and indoor units) is generally high. The inconveniences of traditional detection equipment during use are: Traditional detection equipment such as Figure 5 As shown, the instrument includes a main unit and a meter head. The meter head has two separate measuring pins. When using it, you need to hold the two measuring pins with two hands and then test the voltage on the terminal block. Therefore, the main unit needs to be placed in a stable position. Otherwise, it will cause inconvenience in working.

DETAILED DESCRIPTION

[0022] The preferred solution is Figures 1 to 5 As shown, an air conditioner voltage detection device includes an instrument host 1 and an instrument head 2, wherein the instrument head 2 includes a first soft wire 201 and a second soft wire 202, the first soft wire 201 and the second soft wire 202 are connected to one end of a meter arm 203, and the other end of the meter arm 203 is rotatably or foldably provided with two measuring needles, and the two measuring needles are electrically connected to the first soft wire 201 and the second soft wire 202 respectively.

[0023] Among them: Instrument host 1: adopts more mature products on the market, such as the instrument host 1 of a common multimeter, which has basic voltage detection function.

[0024] Meter head 2: This is the main improvement of the present invention. The meter head includes a first flexible wire 201 and a second flexible wire 202, which are connected to one end of an adjustable meter arm 203. The other end of the meter arm is equipped with two freely rotatable or foldable measuring needles, which are electrically connected to the first and second flexible wires, respectively.

[0025] Specifically, the two measuring needles are a first measuring needle 204 and a second measuring needle 205. The first measuring needle 204 is connected to the meter arm 203 via a first swing arm 206, and the second measuring needle 205 is connected to the meter arm 203 via a second swing arm 207. The first measuring needle 204 is connected to the first swing arm 206 via a corrugated folding member 208; the second measuring needle 205 is connected to the second swing arm 207 via a corrugated folding member 208. The first swing arm 206 and the second swing arm 207 are connected to the meter arm 203 via a locking bolt 209.

[0026] The operator can adjust the angles of the first and second swing arms 206, 207 according to the measurement spacing on the terminal block to adjust the spacing between the first and second measuring pins 204, 205. The purpose of designing the corrugated folding member 208 is to change the angles of the first and second measuring pins 204, 205 to facilitate insertion into the holes on the terminal block and contact with the screws of the terminal block.

[0027] If the distance between two measurement points is too great, traditional separate measuring probes will need to be replaced. However, in most operating conditions, the power supply voltage wires are located on the same terminal block and are not too far apart. Similarly, many voltage signal measurement points are also located on the same terminal block (typically on two adjacent terminals). Therefore, when measuring similar measurement points, the utility model allows the measuring head to be operated with one hand, bringing convenience to measurement work.

[0028] Preferably, the meter arm 203, the first swing arm 206, and the second swing arm 207 are all made of plastic. A measuring wire is threaded through the meter arm 203, the first swing arm 206, and the second swing arm 207. The measuring wire is connected to a measuring needle made of conductive metal. The corrugated folding member 208 is a plastic bellows. The meter arm, the swing arm, and the corrugated folding member are all made of plastic with excellent insulating properties to ensure safety. The measuring needle is made of metal with good conductivity to ensure measurement accuracy.

[0029] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
