Description

Technical Field

[0001] This utility model relates to the field of battery measuring tools, and in particular to a portable battery measuring instrument. Background Technology

[0002] UPS systems, or uninterruptible power supply systems, require regular voltage checks of densely packed battery banks during routine maintenance to ensure continuous power supply to critical data centers during power outages. Different battery models have varying spacing between their electrodes. Currently, traditional manual measurement with a multimeter is commonly used. This method requires workers to hold the measuring probes in both hands, and one hand must also hold the multimeter, making recording inconvenient and the measurement process cumbersome. Therefore, this application presents a portable battery measuring instrument.

[0003] A search revealed Chinese patent document CN102650681A, which discloses a battery measuring tool. This tool includes an operating arm, a measuring arm, measuring needles, connectors, and wires. The operating arm is connected to the measuring arm. The measuring needles include a left measuring needle and a right measuring needle, both mounted on the measuring arm. The connectors include a left connector and a right connector, both mounted on the operating arm. Two wires are provided: one wire connects to the left measuring needle and the left connector at both ends, and the other wire connects to the right measuring needle and the right connector at both ends. Connection holes are provided in the middle of the measuring arm and at one end of the operating arm, with a fixing and adjusting device installed in the connection holes. The operating arm and the measuring arm are flexibly connected through the fixing and adjusting device. Its advantages are that this battery measuring tool is suitable for battery packs of different sizes. Its disadvantages are that, since no measuring instruments are mounted on the tool, in daily maintenance scenarios of UPS systems, one hand needs to hold the measuring tool and the other a multimeter, which also presents inconvenience for recording data. Utility Model Content

[0004] The purpose of this utility model is to provide a portable battery measuring instrument. Two telescopic parts are telescopically and adjustablely installed at both ends of a fixed part. Two contacts are respectively installed on the two telescopic parts, which facilitates the adjustment of the distance between the two contacts to meet the measurement needs of different types of batteries. The measuring instrument is installed on the handle, so that one hand can perform the measurement and the other hand can record the result.

[0005] To achieve the above objectives, this utility model provides a portable battery measuring instrument, including a measuring arm and a handle. The handle is connected to the measuring arm, and two contacts are installed on the measuring arm. The measuring arm includes a fixing member and a telescopic member. The fixing member is fixedly connected to the handle, and the two telescopic members are telescopically adjustable and installed at both ends of the fixing member. The two contacts are respectively installed on the two telescopic members. A measuring instrument is installed on the handle, and the measuring instrument is electrically connected to the two contacts respectively.

[0006] The fixing component is a sleeve structure. Two telescopic components are inserted from both ends of the fixing component. A rack structure is provided on the opposite side of each of the two telescopic components. A reduction motor is installed inside the handle. The output shaft of the reduction motor extends into the fixing component. A gear is installed on the output shaft of the reduction motor. The gear is located between the rack structures on both sides and meshes with the rack structures on both sides simultaneously.

[0007] The two telescopic components have staggered notches at their adjacent ends, and the rack structures are arranged opposite each other in the notches of the two telescopic components.

[0008] The grip is equipped with a first button and a second button to control the forward and reverse rotation of the geared motor.

[0009] The measuring instrument is a DC digital voltmeter.

[0010] An extension arm is installed at one end of the telescopic component that is far apart from the other end, and a contact is installed on the extension arm.

[0011] The telescopic components are provided with threaded holes at their opposite ends. After the bolt is inserted into the extension arm, it is screwed into the threaded hole on the telescopic component.

[0012] The contact area between the telescopic component and the extendable arm is textured.

[0013] The grip is also equipped with a battery compartment for installing a battery; in use, the battery is electrically connected to the device to supply power to it.

[0014] The battery is either a dry cell battery or a rechargeable battery.

[0015] Compared with the prior art, this utility model has the following technical effects:

[0016] 1. In this utility model, two telescopic components are telescopically adjustable and installed at both ends of a fixed component. Two contacts are respectively installed on the two telescopic components, which facilitates the adjustment of the distance between the two contacts to meet the measurement requirements of different types of batteries. A measuring instrument is installed on the handle, so that one hand can perform the measurement and the other hand can record the result.

[0017] 2. This utility model uses a geared motor. When the geared motor rotates, it drives the gear to rotate, which in turn drives the telescopic parts at both ends to extend and retract synchronously, thereby adjusting the distance between the two contacts.

[0018] 3. This utility model features an extendable arm, which, while controlling the length of the contact itself, allows the contact to extend further, facilitating measurement. The ends of the telescopic components that are far apart from each other are provided with threaded holes. After the bolt is inserted into the extendable arm, it is screwed into the threaded hole on the telescopic component, thus facilitating adjustment of the angle of the extendable arm.

[0035] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0036] Example 1:

[0037] See Figure 1-7 A portable battery measuring instrument includes a measuring arm 10 and a handle 20. The handle 20 is connected to the measuring arm 10. Two contacts 40 are mounted on the measuring arm 10. The measuring arm 10 includes a fixing member 11 and telescopic members 12. The fixing member 11 is fixedly connected to the handle 20. The two telescopic members 12 are telescopically adjustable and mounted at both ends of the fixing member 11. The two contacts 40 are respectively mounted on the two telescopic members 12. A measuring instrument 50 is mounted on the handle 20 and is electrically connected to the two contacts 40 respectively.

[0038] Two telescopic components 12 are telescopically adjustable and mounted at both ends of the fixed component 11. Two contacts 40 are respectively mounted on the two telescopic components 12, facilitating adjustment of the distance between the two contacts 40 to meet the measurement requirements of different battery models. A measuring instrument 50 is mounted on the handle 20, allowing for measurement with one hand and recording with the other.

[0039] In this embodiment, the measuring instrument 50 can be a small multimeter, which can be fixed to the handle 20 via a mounting bracket.

[0040] In this embodiment, the measuring arm 10 can adopt a telescopic structure of the central pole of an umbrella.

[0041] Example 2:

[0042] Based on Example 1, see Figures 3 to 7 The fixing member 11 is a sleeve structure. Two telescopic members 12 are inserted from both ends of the fixing member 11. A rack structure 122 is provided on each opposite side of the two telescopic members 12. A reduction motor 60 is installed inside the handle 20. The output shaft of the reduction motor 60 extends into the fixing member 11. A gear 61 is installed on the output shaft of the reduction motor 60, located between the two rack structures 122, and simultaneously meshes with both rack structures 122. By installing the reduction motor 60, when the reduction motor 60 rotates, it drives the gear 61 to rotate, thereby causing the telescopic members 12 at both ends to extend and retract synchronously, thus adjusting the distance between the two contacts 40.

[0043] Further, see Figure 5 , 6 7. At the adjacent ends of the two telescopic components 12, there are staggered notches 121, and rack structures 122 are provided opposite to each other in the notches 121 of the two telescopic components 12.

[0044] Furthermore, to facilitate the forward and reverse rotation control of the geared motor 60, a first button 21 and a second button 22 for controlling the forward and reverse rotation of the geared motor 60 are installed on the grip 20.

[0045] In one of the schemes, see Figure 8 This is a circuit diagram for controlling the forward and reverse rotation of the geared motor 60. The forward and reverse rotation of the geared motor 60 is controlled by pressing either the first button 21 or the second button 22.

[0046] Of course, other methods can be used to control the forward and reverse rotation of the geared motor, such as interlock control. Figure 8 This is just one example.

[0047] Example 3:

[0048] The difference between this embodiment and Embodiment 1 or Embodiment 2 is that the measuring instrument is a DC digital voltmeter. The DC digital voltmeter is embedded in the handle 20.

[0049] Specifically, the measuring instrument used is a DC digital voltmeter, model PZEM-025. This DC digital voltmeter has a power supply voltage of DC 5V~12V and a measuring voltage range of DC 0.05~300V.

[0050] For easier power supply to the measuring instruments, see [link / reference]. Figure 3 The handle 20 also has a battery compartment 23 for storing batteries. In use, the battery is electrically connected to the device to supply power. The device includes a measuring instrument 50 and a geared motor 60.

[0051] The battery can be either a dry cell battery or a rechargeable battery.

[0052] It should be noted that the dry cell battery can use four AA batteries, while the rechargeable battery can use a lithium battery. When using a lithium battery, a charging port can also be provided on the grip 20. The charging circuit and method for lithium batteries are existing technology; for example, some toys have charging ports, so they will not be described in detail here.

[0053] Example 4:

[0054] Based on Example 1, Example 2, or Example 3, see [link to example]. Figures 1 to 4 An extension arm 30 is installed at one of the ends of the telescopic component 12 that is far apart from the other end, and the contact 40 is mounted on the extension arm 30. The extension arm 30 is provided so that the contact 40 can extend further while controlling the length of the contact itself, which is convenient for measurement.

[0055] Furthermore, in order to facilitate the adjustment of the angle of the extension arm 30, the ends of the telescopic components 12 that are far apart from each other are provided with threaded holes. After the bolt 31 is inserted into the extension arm 30, it is screwed into the threaded hole on the telescopic component 12.

[0056] In this embodiment, bolt 31 is a hand-tightening bolt. By turning bolt 31, the extension arm 30 can be swung and adjusted. After adjustment, bolt 31 is tightened.

[0057] Furthermore, the contact area between the telescopic member 12 and the extendable arm 30 is textured. This increases the friction between the extendable arm 30 and the telescopic member 12, preventing the extendable arm 30 from rotating during use.

[0058] See Figure 4 The telescopic component 12 is a rectangular tube, and a plug 13 is fixedly provided at the end of the telescopic component 12 that connects to the extension arm 30. The plug 13 has a threaded hole. The extension arm 30 is a rectangular tube structure, and the wire connecting the measuring instrument 50 to the contact head 40 passes through the extension arm 30. The contact head 40 is fixedly inserted into the extension arm 30.

[0059] The method of use or principle of this utility model:

[0060] When using, please refer to Figures 1 to 3 After the battery is installed, the geared motor 60 can be controlled to rotate forward and backward by pressing the first button 21 or the second button 22, thereby driving the telescopic parts 12 at both ends to extend and retract synchronously, thereby adjusting the distance between the two contacts 40. The distance between the two contacts 40 is adapted to the two electrodes of the battery.

[0061] When the angle of the extension arm 30 needs to be adjusted, tighten the bolt 31 to swing and adjust the extension arm 30. After adjustment, tighten the bolt 31.

[0062] During measurement, hold the handle 20 and place the two contacts 40 against the two electrodes of the battery respectively, and display the voltage through the measuring instrument 50.

[0063] It should be noted that, see Figure 4 In this application, the measuring arm 10, handle 20, and extendable arm 30 are all made of insulating materials, such as plastic. The contact 40 is made of conductive materials, such as copper. Figure 4 The diagram also shows the positive and negative terminals of the battery compartment supplying power to the measuring instrument 50 via wires, and the measuring instrument 50 being electrically connected to the contact 40 via wires.
