Description

Technical Field

[0001] This application relates to the field of resistance measuring equipment technology, and in particular to a detachable resistance measuring device. Background Technology

[0002] In the production, research and development, and testing of electronic components, resistors, as one of the most basic electronic components, require precise measurement to ensure the quality and performance of electronic products. Traditional resistance measuring devices mostly employ a fixed structure, with the measuring body and resistor placement area integrated into one unit. This structure has several limitations: firstly, when measuring resistors of different specifications and shapes, the limited space and fixing method of the resistor placement area make it difficult to flexibly adjust, failing to meet diverse measurement needs and potentially affecting the accuracy of measurement results due to improper fixing; secondly, when a part of the measuring device malfunctions or requires maintenance or calibration, the non-disassembly of the overall structure necessitates disassembly and repair by personnel, which is not only cumbersome and time-consuming but also prone to damaging other normal components during disassembly, increasing maintenance costs and equipment downtime. Furthermore, in traditional measuring devices, the position of the measuring probe is usually fixed or the adjustment method is inconvenient, making it difficult to quickly and accurately align the resistor measurement point, affecting measurement efficiency and accuracy.

[0003] To address the problems mentioned above, a detachable resistance measuring device has been invented. Utility Model Content

[0004] The purpose of this invention is to provide a detachable resistance measuring device to solve the problems of fixed structure, difficulty in adapting to different resistance specifications, inconvenient maintenance, and inflexible adjustment of the measuring probe position in existing resistance measuring devices. Through detachable design, flexible resistance fixing and measuring probe adjustment structure, the efficiency, accuracy and maintainability of resistance measurement are improved.

[0005] This application provides a detachable resistance measuring device, which adopts the following technical solution: it includes a measuring main frame and a resistance fixing frame, wherein the measuring main frame and the resistance fixing frame can be separated, the measuring main frame is provided with a horizontal sliding groove, a sliding seat is provided in the horizontal sliding groove, a measuring probe for measuring resistance is provided on the sliding seat, and the resistance fixing frame is used to place the resistor.

[0006] Optionally, the measuring main frame is provided with a limiting component that can limit the position of the sliding seat. The limiting component includes slots evenly distributed on both sides of the horizontal slide groove. Each side of the sliding seat is slidably connected to a locking block that can be inserted into the corresponding slot. The locking block is provided with a fixing spring, and the other end of the fixing spring is fixedly connected to the sliding seat.

[0007] Optionally, each of the card blocks is provided with a push plate on top.

[0008] Optionally, the resistor fixing frame includes a fixing base, a concave groove in the middle of the fixing base for placing a resistor, a slidable sliding frame in the middle of the fixing base, an adjusting screw on the sliding frame, a pressure plate at the bottom of the adjusting screw above the concave groove, and an adjusting handle at the top of the adjusting screw.

[0009] Optionally, a pin is provided on one end of the fixed base near the main measuring frame, a limiting groove is provided on the pin, a limiting rod is provided on the main measuring frame that can be inserted into the limiting groove, a limiting spring is fitted and fixed on the limiting rod, the other end of the limiting spring is fixedly connected to the main measuring frame, and a pull ring is provided on the other end of the limiting rod.

[0010] In summary, this application includes the following beneficial technical effects: 1. Detachable Design: The main measuring frame and the resistor fixing frame are separable. When a part of the device malfunctions, the corresponding part can be quickly disassembled for repair or replacement, greatly reducing the difficulty and time cost of maintenance, while also reducing the risk of damage to other components during maintenance. Furthermore, this design facilitates the transportation and storage of the device and allows for flexible combination and use according to actual needs.

[0011] 2. Flexible probe adjustment: A horizontal groove is provided on the main frame of the measuring instrument, allowing the sliding seat to slide within the groove. The probe on the sliding seat can be easily adjusted in position, enabling quick and accurate alignment with resistance measurement points of different specifications and locations, significantly improving measurement efficiency and accuracy. The limiting component ensures that the sliding seat is stably fixed after being adjusted to the appropriate position, preventing measurement results from being affected by movement of the sliding seat during the measurement process.

[0012] 3. Convenient resistor fixing: The fixing base in the resistor fixing frame has a concave groove in the middle for placing the resistor. By adjusting the screw, pressure plate and adjusting handle, resistors of different specifications can be easily fixed, ensuring that the resistor is in a stable position during the measurement process and further improving the accuracy of the measurement.

[0013] 4. Stable connection structure: The fixed base and the main measuring frame are stably connected through the cooperation of the insert, limiting groove, limiting rod, limiting spring and pull ring, which ensures that the resistance fixed frame and the main measuring frame will not easily separate during the measurement process, and ensures the smooth progress of the measurement work.

[0015] The present application will be further described in detail below with reference to the accompanying drawings. In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model.

[0016] Reference Figure 1 , Figure 2One embodiment shown is as follows: The measuring device consists of a measuring main frame 1 and a resistor fixing frame 2, which are independent and separable. A horizontal groove 3 is machined on the measuring main frame 1, extending horizontally. A sliding seat 4 is embedded in the horizontal groove 3, with a clearance fit between them, allowing the sliding seat 4 to slide smoothly back and forth within the horizontal groove 3. A measuring probe 5 is fixedly mounted on the top of the sliding seat 4 by bolts. A constant current source and a voltage detection module are also installed inside the measuring main frame 1. A display screen is fixedly mounted on one side of the measuring main frame 1. The measuring probe 5 adopts a high-precision probe design, with a built-in alloy contact with excellent conductivity at its working end. During measurement, the contact forms a tight electrical contact with the resistor pin, constructing a complete measuring circuit. The specific measurement process is as follows: Circuit construction: The measuring probe 5 is connected to the constant current source and voltage detection module inside the measuring device body via wires. When the contact contacts the resistor pin, the constant current source injects a stable test current into the circuit. Voltage acquisition: Due to the presence of resistance, a voltage drop proportional to the resistance value will occur across the resistor. The voltage detection module acquires the voltage signal in real time and converts the analog signal into a digital signal. Data processing: After receiving the digital signal, the built-in microprocessor of the measuring device quickly calculates the precise resistance value by dividing the acquired voltage value by the injected current value. Result output: The final calculation result is presented intuitively on the device's display screen or transmitted to an external device via a communication interface, thereby achieving accurate resistance measurement. The resistor fixing frame 2 is an independent component, its main function being to provide placement space for the resistor.

[0017] The implementation principle of the above embodiment is as follows: by separating the main measuring frame 1 from the resistor fixing frame 2, it can be flexibly disassembled and reassembled when maintenance of the device or measurement of resistors of different specifications is required. The sliding function of the sliding seat 4 within the horizontal slide groove 3 allows the measuring probe 5 to be adjusted according to the position of the resistor, ensuring that the measuring probe 5 accurately contacts the resistor pins and achieves precise measurement.

[0018] Reference Figure 1 , Figure 5 , Figure 6One embodiment is shown as follows: Multiple slots 7 are uniformly machined on both sides of the horizontal slide groove 3 within the main measuring frame 1. These slots 7 are used to cooperate with the locking blocks 8 to achieve a limiting function. Vertical sliding grooves adapted to the locking blocks 8 are respectively opened on both sides of the sliding seat 4. The locking blocks 8 form a sliding connection with the sliding seat 4 through the vertical sliding grooves, allowing them to slide vertically up and down within the vertical sliding grooves. The end of the locking block 8 near the locking groove 7 is wedge-shaped for easy insertion into the groove 7. Inside the sliding seat 4, a fixing spring 9 is bolted to the position of each locking block 8. The other end of the fixing spring 9 is fixedly connected to the locking block 8, which can be achieved by welding. In its natural state, the fixing spring 9 is in a compressed state, providing a thrust to the locking block 8 towards the locking groove 7.

[0019] The implementation principle of the above embodiment is as follows: when the sliding seat 4 slides in the horizontal sliding groove 3 to adjust the position of the measuring probe 5, the locking block 8 slides upward in the vertical sliding groove due to the pressure of the side wall of the horizontal sliding groove 3. When the sliding seat 4 moves to the appropriate position, the locking block 8 aligns with the corresponding locking groove 7. Under the elastic force of the fixing spring 9, the locking block 8 is inserted into the locking groove 7, thereby restricting the movement of the sliding seat 4, ensuring that the position of the measuring probe 5 is stable during the measurement process, and avoiding the measurement result being affected by the movement of the sliding seat 4.

[0020] Reference Figure 3 , Figure 4 One embodiment shown is as follows: A push plate 10 is fixedly installed on the top of each locking block 8 by welding. The push plate 10 is a rectangular plate structure, and its size is larger than the top of the locking block 8, so that it is easy for the operator to push it by hand. The push plate 10 is tightly connected to the locking block 8, and can accurately transmit the external force applied by the operator to the locking block 8.

[0021] The implementation principle of the above embodiment is as follows: When it is necessary to adjust the position of the sliding seat 4, the operator pushes the push plate 10 by hand. The push plate 10 causes the locking block 8 to slide upward against the elastic force of the fixing spring 9, so that the locking block 8 disengages from the locking groove 7. At this time, the sliding seat 4 can slide freely in the horizontal sliding groove 3, thereby facilitating the adjustment of the position of the measuring probe 5. The push plate 10 makes it easier and more convenient for the operator to operate the locking block 8, improving the ease of use of the device.

[0022] Reference Figure 1 , Figure 2One embodiment shown is as follows: The fixing base 11 of the resistor fixing frame 2 is a square plate structure. A concave groove 12 is machined in the middle of the fixing base 11. The shape and size of the concave groove 12 can accommodate resistors of various specifications, providing a stable placement space for the resistors. A sliding frame 13 is slidably connected to the fixing base 11. An adjusting screw 14 is installed on the sliding frame 13 by a threaded connection. The top of the adjusting screw 14 extends out of the sliding frame 13 and is fixedly installed with an adjusting handle 16. The adjusting handle 16 has a circular disc structure, which is convenient for the operator to rotate. The bottom of the adjusting screw 14 passes through the sliding frame 13 and is fitted with a pressure plate 15 by welding. The bottom of the adjusting screw 14 and the pressure plate 15 are rotatably connected, allowing relative rotation. The pressure plate 15 has an arc-shaped structure, which can cover the resistor in the concave groove 12.

[0023] The implementation principle of the above embodiment is as follows: After the resistor is placed in the concave groove 12, the operator rotates the adjusting handle 16, which drives the adjusting screw 14 to rotate. Since the adjusting screw 14 and the sliding frame 13 are threadedly connected, the rotation of the adjusting screw 14 is converted into the up-and-down movement of the sliding frame 13, which in turn drives the pressure plate 15 to move up and down. When the pressure plate 15 moves downward, it can press the resistor tightly into the concave groove 12, achieving stable fixation of the resistor and ensuring that the resistor will not be displaced during the measurement process, thereby improving the accuracy of the measurement.

[0024] Reference Figure 3 , Figure 4 One embodiment is shown as follows: A cylindrical insert 17 is fixedly installed on the end of the fixed base 11 near the measuring main frame 1 by welding. A limiting groove 18 is machined on the side of the insert 17. A limiting rod 19 is allowed to slide linearly within the guide sleeve at a position corresponding to the insert 17 on the measuring main frame 1 by creating a through hole and installing a guide sleeve. One end of the limiting rod 19 passes through the guide sleeve and can be inserted into the limiting groove 18 of the insert 17. A limiting spring 20 is fitted onto the limiting rod 19. One end of the limiting spring 20 is fixed to the measuring main frame 1 by welding, and the other end contacts the limiting rod 19. In its natural state, the limiting spring 20 is compressed, providing a thrust towards the insert 17 for the limiting rod 19. A pull ring 21, which is circular in shape, is fixedly installed on the other end of the limiting rod 19 by welding for easy pulling by the operator.

[0025] The implementation principle of the above embodiment is as follows: When connecting the resistor fixing frame 2 and the measuring main frame 1, pull the pull ring 21 to allow the limiting rod 19 to overcome the elastic force of the limiting spring 20 and be pulled out from the limiting groove 18 of the insertion post 17. Insert the insertion post 17 on the fixing seat 11 into the corresponding position of the measuring main frame 1. Release the pull ring 21, and under the elastic force of the limiting spring 20, the limiting rod 19 is inserted into the limiting groove 18, thus achieving a stable connection between the resistor fixing frame 2 and the measuring main frame 1. This connection method is simple to operate and can ensure the stability of the connection. It will not easily separate during the measurement process. At the same time, when disassembly is required, it can be easily separated by pulling the pull ring 21, which is convenient and quick.

[0026] The working principle of this device is as follows: First, place the resistor in the concave groove 12 of the fixed base 11. Rotate the adjusting handle 16 to drive the adjusting screw 14 to rotate, causing the pressure plate 15 to press down and fix the resistor. Next, pull the pull ring 21 to pull out the limiting rod 19, insert the insertion post 17 of the fixed base 11 into the corresponding position of the measuring main frame 1, and release the pull ring 21. Under the action of the limiting spring 20, the limiting rod 19 inserts into the limiting groove 18, completing the frame connection. Then, push the top push plate 10 of the locking block 8 to disengage the locking block 8 from the locking groove 7. The sliding seat 4 slides in the horizontal sliding groove 3. After aligning the measuring probe 5 with the resistance measurement point, release the push plate 10. Under the elastic force of the fixing spring 9, the locking block 8 re-locks into the locking groove 7 to fix the sliding seat 4. Finally, the measuring probe 5 and the resistor form a measuring circuit, and the device completes the resistance measurement. For disassembly, pull the pull ring 21 again to separate the frame, facilitating subsequent operation and maintenance.

[0027] The working principle of this device has been explained through the above embodiments.
