Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of resistance testing, in particular to a resistance testing device. Background Art
[0002] A resistance tester is a device or system used to measure resistance values. Resistance testing is very common in electronics, electrical engineering and other fields. It is used to detect the resistance value in components, circuits or systems to ensure their normal operation or for fault diagnosis.
[0003] Resistance testing devices are generally used in conjunction with cables, and a clamp is provided at one end of the cable, and the staff can use the clamp to clamp the test position. In addition, in order to facilitate the use of the resistance testing device, the cable is usually longer, but the resistance testing device in the prior art does not have the function of winding and storing the cable, and the cables need to be stored separately. Storing the cables separately may cause confusion in space management. Long cables may take up too much space in the working area, causing clutter or being intertwined around other equipment, increasing the risk of accidental tripping or damage. In addition, long cables may be more easily knotted or entangled, making it take more time to untangle when testing is required, affecting work efficiency. In addition, long-term use and storage may cause damage or aging of the cables, increasing maintenance costs and frequency.
[0004] Therefore, it is necessary to design a resistance testing device to solve the above problems. Utility Model Content

The outer cylinder is fixed on the resistance tester, the inner rod is slidably connected in the outer cylinder, and one end of the inner rod extends to the outside of the outer cylinder, and the end of the inner rod located outside the outer cylinder is rotatably connected to the winding disk through a bearing, the slideway is opened on the outer surface of the outer cylinder, the slider is fixed on the inner rod, and the slider is slidably connected in the slideway.
[0009] As a preferred technical solution of the utility model, a knob is fixed on the winding disk, and the winding disk and the knob are coaxially arranged.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] Reference Figure 1-4 A resistance testing device includes a resistance tester 1, a fixing ring 2 is fixed on the resistance tester 1, a winding disk 3 is arranged inside the fixing ring 2, a notch 9 is opened on the winding disk 3, the winding disk 3 is connected to the resistance tester 1 through a connecting component, and the staff winds the cable on the winding disk 3. The staff can realize this process by turning the winding disk 3 by turning the knob 10. After the cable is wound up, the staff pushes the winding disk 3 into the fixing ring 2. At this time, the outer surface of the winding disk 3 and the inner circle of the fixing ring 2 are in contact with each other, which can prevent the cable from falling off the winding disk 3, thereby realizing the storage function of the cable.
[0021] Reference Figure 3 The connecting assembly includes an outer cylinder 4, an inner rod 5, a slideway 6, a slider 7 and a bearing 8. The outer cylinder 4 is fixed on the resistance tester 1, the inner rod 5 is slidably connected in the outer cylinder 4, and one end of the inner rod 5 extends to the outside of the outer cylinder 4. The end of the inner rod 5 located outside the outer cylinder 4 is rotatably connected to the winding disk 3 through the bearing 8. The slideway 6 is opened on the outer surface of the outer cylinder 4, the slider 7 is fixed on the inner rod 5, and the slider 7 is slidably connected in the slideway 6. When the winding disk 3 moves, it can drive the inner rod 5 to move, so that the inner rod 5 moves out of the outer cylinder 4. In this process, the slideway 6 and the slider 7 limit the movement of the inner rod 5, thereby ensuring the stability of the winding disk 3 during the movement.
[0022] Reference Figure 4 A knob 10 is fixed on the winding disk 3 , and the winding disk 3 and the knob 10 are coaxially arranged, so that the staff can use the knob 10 to rotate the winding disk 3 conveniently.
[0023] Reference Figure 2 The outer surface of the winding drum 3 and the inner ring of the fixing ring 2 fit together, which can prevent the cable from falling off the winding drum 3.
[0024] Reference Figure 3 The inner surface of the outer tube 4 and the outer surface of the inner rod 5 fit together, which can ensure the connection stability between the outer tube 4 and the inner rod 5.
[0025] The specific working principle of the utility model is as follows:
[0026] When the cable is wound, the staff first pulls the winding drum 3 through the knob 10 to move the winding drum 3 out of the fixing ring 2. When the winding drum 3 moves, it can drive the inner rod 5 to move, so that the inner rod 5 moves out of the outer cylinder 4. In this process, the slideway 6 and the slider 7 play a limiting role in the movement of the inner rod 5, thereby ensuring the stability of the winding drum 3 during the movement. When the winding drum 3 moves out of the fixing ring 2, the staff can wind the cable on the winding drum 3. The staff can achieve this process by rotating the winding drum 3 through the knob 10. After the cable is wound, the staff pushes the winding drum 3 into the fixing ring 2. At this time, the outer surface of the winding drum 3 and the inner ring of the fixing ring 2 are in contact with each other, which can prevent the cable from falling off the winding drum 3, thereby realizing the cable storage function. In addition, a notch 9 is provided on the winding drum 3, and the staff can insert one end of the cable near the clamp into the notch 9.
[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
