[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.
[0020] like Figures 1 to 4 As shown, an embodiment of the utility model provides a battery voltage detection device, which includes a first frame 1, a second frame 2, an insulating handle 3, an adjustment mechanism 4, a movable meter head 5, a fixed meter head 6 and a voltage detection mechanism 7.
[0021] In practical applications, the length of the first frame 1 is retractable. The retractable length of the first frame 1 allows the length of the first frame 1 to be adjusted when detecting batteries at different positions, thereby improving the applicability of the battery voltage detection device.
[0022] like Figure 1As shown, one end of the first frame 1 and one end of the second frame 2 are connected by a fixing member 9. In practical applications, the first frame 1 and the second frame 2 are both hollow cylindrical, so as to facilitate the insertion of the test wire in the voltage detection mechanism 7. The materials of the first frame 1 and the second frame 2 are both epoxy resin, which has high insulation performance and can effectively isolate the current to prevent electrical equipment from electric shock and other dangers. At the same time, it also has excellent heat resistance and corrosion resistance, and can work for a long time in high temperature and harsh environment. In addition, epoxy resin also has good mechanical strength and anti-puncture ability, which can effectively protect electrical equipment from external physical damage. Specifically, the fixing member 9 is a nylon plastic screw.
[0023] like Figure 2 As shown, the insulating handle 3 is sleeved on the end of the first frame 1 away from the second frame 2. The fixed meter head 6 is fixed on the end of the second frame 2 away from the first frame 1. In practical applications, the insulating handle 3 can prevent the tester from directly touching the first frame 1, thereby ensuring the personal safety of the tester and further improving the safety performance of the detection device.
[0024] Continue to refer to Figure 3 As shown, the adjustment mechanism 4 is arranged on the second frame 2 and is located between the fixed meter head 6 and the first frame 1. The movable meter head 5 is fixed on the adjustment mechanism 4, and the adjustment mechanism 4 can drive the movable meter head 5 to move on the second frame 2. The movable meter head 5 and the fixed meter head 6 are both electrically connected to the voltage detection mechanism 7. By driving the movable meter head 5 to move on the second frame 2 by the adjustment mechanism 4, the distance between the movable meter head 5 and the fixed meter head 6 can be adjusted, so as to meet the measurement of batteries of different sizes.
[0025] The embodiment of the utility model provides a battery voltage detection device, which includes a first frame 1, a second frame 2, an insulating handle 3, an adjusting mechanism 4, a movable meter head 5, a fixed meter head 6 and a voltage detection mechanism 7. The length of the first frame 1 is retractable. One end of the first frame 1 and one end of the second frame 2 are connected by a fixing member 9. The insulating handle 3 is sleeved on an end of the first frame 1 that is away from the second frame 2. The fixed meter head 6 is fixed on an end of the second frame 2 that is away from the first frame 1. The adjusting mechanism 4 is arranged on the second frame 2 and is located between the fixed meter head 6 and the first frame 1. The movable meter head 5 is fixed on the adjusting mechanism 4, and the adjusting mechanism 4 can drive the movable meter head 5 to move on the second frame 2. The movable meter head 5 and the fixed meter head 6 are both electrically connected to the voltage detection mechanism 7. When detecting the battery voltage, the movable meter head 5 is first moved by the adjustment mechanism 4 to adjust the distance between the movable meter head 5 and the fixed meter head 6 to be consistent with the size of the battery to be tested, and then the voltage detection mechanism 7 is turned on. Then the operator holds the insulating handle 3 and moves the detection device to the battery to be tested, so that the fixed meter head 6 and the positive electrode of the battery to be tested are reliably contacted, and the movable meter head 5 and the negative electrode of the battery to be tested are reliably contacted, so that the battery voltage can be quickly detected. When detecting the battery voltage, the present application only needs one operator to complete it, which reduces the detection cost and detection workload, improves the detection efficiency and detection accuracy, and at the same time, during the detection process, the operator does not need to extend his arm into the battery rack, which is highly safe.
[0026] like Figure 1 and Figure 3As shown, the adjustment mechanism 4 includes an adjustable limit ring 41 and a fixing bolt 42. A limit groove extending along the length direction of the second frame 2 is provided on the second frame 2. The adjustable limit ring 41 and the limit groove are slidably connected. The movable gauge head 5 is fixed on the adjustable limit ring 41. A threaded hole is provided on the adjustable limit ring 41. One end of the fixing bolt 42 passes through the threaded hole and abuts against the second frame 2. In actual application, when it is necessary to slide the adjustable limit ring 41, adjust the fixing bolt 42 so that the end of the fixing bolt 42 is away from the second frame 2, and then slide the adjustable limit ring 41 to the desired position, and then adjust the fixing bolt 42 so that the end of the fixing bolt 42 abuts against the second frame 2 to fix the adjustable limit ring 41. The material of the adjustable limit ring 41 is polyoxymethylene engineering plastic, and the size is 22mm×35mm×12mm (inner diameter×outer diameter×wall thickness). Specifically, the second frame 2 has a length of 270 mm, an outer diameter of 18 mm, an inner diameter of 16 mm, and a limiting groove with a size of 170 mm × 35 mm (length × width) is opened at the center position 30 mm away from the left edge; the movable meter head 5 is installed at the center position of the adjustable limiting ring 41, and the second frame 2 has a hole opened at the center position 10 mm away from the right edge to install the fixed meter head 6. The movable meter head 5 and the fixed meter head 6 are both 15 mm high. By adjusting the movable meter head 5, the distance between the movable meter head 5 and the fixed meter head 6 can be adjusted to meet the detection of batteries of different sizes, thereby realizing the rapid detection of battery voltage with a positive and negative pole distance of 60 mm-220 mm.
[0027] Continue to refer to Figure 2 As shown, the voltage detection mechanism 7 includes a first test wire 71, a second test wire 72 and a voltage detection unit 73. One end of the first test wire 71 is connected to the positive pole of the voltage detection unit 73, and the other end of the first test wire 71 is connected to the fixed meter head 6. One end of the second test wire 72 is connected to the negative pole of the voltage detection unit 73, and the other end of the second test wire 72 is connected to the movable meter head 5. Specifically, the first test wire 71 and the second test wire 72 are both arranged in the inner cavity of the first frame 1 and the second frame 2 to avoid the first test wire 71 and the second test wire 72 being exposed to the air, thereby eliminating safety hazards. In actual use, the voltage detection unit 73 can be replaced by a multimeter. When detecting the battery voltage, the voltage detection unit 73 is first turned on, and then the voltage conversion switch 10 is rotated to the corresponding gear position, and then the detection device is moved to make the fixed meter head 6 reliably contact the positive pole of the battery to be tested, and the movable meter head 5 reliably contact the negative pole of the battery to be tested. At this time, the voltage displayed on the display 11 is the voltage to be tested.
[0028] like Figure 1As shown, the first frame 1 includes a first segment 1a, a second segment 1b and a third segment 1c. The first segment 1a is sleeved on the second segment 1b, and the first segment 1a can slide along the axial direction of the second segment 1b. An insulating handle 3 is sleeved on the end of the first segment 1a away from the second segment 1b. The second segment 1b is sleeved on the third segment 1c, and the second segment 1b can slide along the axial direction of the third segment 1c. The end of the third segment 1c away from the second segment 1b is connected to one end of the second frame 2 by a fixing member 9. In practical applications, the maximum extension length of the first frame 1 is 630mm, the extension length of the first segment 1a is 250mm, the outer diameter is 25mm, and the inner diameter is 23mm; the extension length of the second segment 1b is 200mm, the outer diameter is 23mm, and the inner diameter is 21mm; the extension length of the third segment 1c is 180mm, the outer diameter is 21mm, and the inner diameter is 19mm.
[0029] In practical applications, the battery voltage detection device further includes a reinforcement mechanism 8. The reinforcement mechanism 8 is disposed at the connection between the first frame 1 and the second frame 2. Specifically, the reinforcement mechanism 8 can reinforce the connection between the first frame 1 and the second frame 2 to improve the reliability and service life of the detection device.
[0030] like Figure 4 As shown, the reinforcement mechanism 8 includes a reinforcement support 81. One end of the reinforcement support 81 is connected to the first frame 1, and the other end of the reinforcement support 81 is connected to the second frame 2. In practical applications, the connection between the first frame 1 and the second frame 2 is reinforced by two reinforcement supports 81, and the reinforcement support 81 is fixed to the first frame 1 and the second frame 2 by nylon plastic screws. Specifically, the reinforcement support 81 is made of the highest strength epoxy resin insulation material, and the size of the reinforcement support 81 is 60mm×20mm×2mm (length×width×thickness).
