Description
Technical Field
[0001] This utility model relates to the field of testing equipment, and in particular to a testing device with automatic probe detection function. Background Technology
[0002] A multimeter, also known as a multi-purpose meter, is an indispensable measuring instrument in the power electronics and other related industries. Its primary purpose is to measure voltage, current, and resistance. Multimeters are classified into analog multimeters and digital multimeters based on their display method. They are multifunctional, multi-range measuring instruments. A typical multimeter can measure DC current, DC voltage, AC current, AC voltage, resistance, and audio levels. Some multimeters can also measure AC current, capacitance, inductance, and certain semiconductor parameters (such as beta).
[0003] When using a multimeter, tests are performed through two probes connected to the bottom. The red probe is connected to the positive terminal of a diode, and the black probe to the negative terminal. During testing, the results are automatically displayed on the screen of the multimeter, which can be read directly by the operator. After testing, the two probes can be placed into the two movable slots on the back of the multimeter's mounting bracket. However, existing testing equipment with automatic probe detection also has some shortcomings in use:
[0004] 1. In existing testing equipment, after the test leads are placed into the mounting bracket, the cables connecting the test leads and the test meter are directly stacked, which easily leads to tangling and knotting.
[0005] 2. When using existing test tables, in order to facilitate the reading of results by staff, an additional device is usually required to support the test table, which is quite inconvenient.
[0006] Therefore, it is necessary to provide a new testing device with automatic probe detection function to solve the above-mentioned technical problems. Utility Model Content
[0007] To solve the above-mentioned technical problems, this utility model provides a testing device with automatic probe detection function.
[0008] The testing device with automatic probe detection function provided by this utility model includes a test meter. The bottom of the test meter is connected to two probes via two cables. A mounting base for placing the two probes is installed on the back of the test meter. Rotating devices are provided on both sides of the mounting base on the back of the test meter. A winding cylinder is installed on the rotating end of the rotating device. A winding rod is provided on one side of the winding cylinder along a straight direction. The distance between the winding cylinder and the winding rod is adjustable. Sleeves are fixedly fitted on both the winding cylinder and the winding rod. A limiting device for limiting the cables is installed on the ends of the two sleeves that are far apart.
[0009] Preferably, the rotating device includes a rotating rod and two support plates, both of which are fixedly connected to the test gauge. The two ends of the rotating rod are respectively movably disposed in the placement slots opened in the two support plates, and the rotating rod is fixedly connected to the winding cylinder.
[0010] Preferably, the outer surfaces of both ends of the rotating rod are provided with multiple grooves arranged in a ring. Springs are fixedly connected to each of the multiple grooves of the rotating rod. One end of the spring is fixedly connected to a limiting post. The end of the limiting post away from the spring is hemispherical. The hemispherical ends of the multiple limiting posts at one end of the rotating rod can be moved into the multiple grooves opened in the inner wall of the placement groove.
[0011] Preferably, one end of the winding rod is fixedly connected to a threaded rod, and the threaded rod is threadedly connected to the inner wall of the winding cylinder.
[0012] Preferably, the limiting device includes a threaded ring, a movable ring, and multiple limiting brackets. The threaded ring is threadedly fitted onto the sleeve, the movable ring is movably fitted onto the sleeve, the movable ring is rotatably connected to the threaded ring, and the multiple limiting brackets are uniformly fixedly connected to the outer surface of the movable ring.
[0013] Preferably, a sliding block is fixedly connected to the inner wall of the movable ring, and the sliding block can slide within a groove opened on the side wall of the sleeve.
[0014] Preferably, the limiting frame has an L-shaped structure, the inner side of the end of the L-shaped structure of the limiting frame is inclined, and a rubber pad is fixedly connected to the inner side of the limiting frame.
[0015] Preferably, the end of the winding rod away from the winding cylinder is fixedly connected to an anti-slip block, which has a hemispherical structure.
[0016] Preferably, the mounting base is provided with two movable slots for placing two probes respectively. Rubber strips are fixedly connected to the two inner walls of the movable slots. Slots are opened on the side walls of the two movable slots, and the circular plates at the ends of the probes can be moved into the slots.
[0017] Compared with related technologies, the testing equipment with automatic probe detection function provided by this utility model has the following advantages:
[0018] 1. The winding rod drives the rotating rod to rotate through the threaded rod and winding cylinder. According to actual needs, the winding rod is rotated so that the threaded rod screws in or out of the threaded cylinder. The adjustable distance winding rod and winding cylinder facilitate the support of the test gauge.
[0019] 2. Wrap the cable around the sleeve of the winding cylinder. Then, use the limiting device to limit the cable's rotation. Continue to wrap the cable around the two sleeves. When the cable reaches the bottom of the sleeve on the winding rod, use another limiting device to limit the cable's rotation for easy cable storage. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0028] Please refer to the following: Figures 1-6 ,in, Figure 1 A schematic diagram of the structure of the testing device with automatic probe detection function provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the structure from another angle is shown;

[0030] In the specific implementation process, such as Figures 1-6 As shown, the test meter 1 is a multimeter. The bottom of the test meter 1 is connected to two probes 2 by two cables. The test meter 1 is a multimeter. The back of the test meter 1 is equipped with a mounting base 3 for placing the two probes 2. Rotating devices are provided on both sides of the back of the test meter 1 located on the mounting base 3. A winding cylinder 5 is installed on the rotating end of the rotating device. A winding rod 4 is provided on one side of the winding cylinder 5 along a straight direction. The distance between the winding cylinder 5 and the winding rod 4 can be adjusted. Sleeves 6 are fixedly sleeved on both the winding cylinder 5 and the winding rod 4. Limiting devices for limiting the cables are installed on the ends of the two sleeves 6 that are far apart.
[0031] The rotating device includes a rotating rod 9 and two support plates 7, both of which are fixedly connected to the test gauge 1. The two ends of the rotating rod 9 are movably positioned within placement slots 8 opened in the two support plates 7. The rotating rod 9 is fixedly connected to the winding cylinder 5. Multiple annularly distributed grooves are opened on the outer surfaces of both ends of the rotating rod 9. Springs 10 are fixedly connected to each of the multiple grooves of the rotating rod 9. A limiting post 11 is fixedly connected to one end of each spring 10. The end of the limiting post 11 away from the spring 10 is hemispherical. The hemispherical ends of the multiple limiting posts 11 at one end of the rotating rod 9 are movable. The winding rod 4 is inserted into the multiple grooves opened on the inner wall of the placement groove 8. The winding rod 4 drives the rotating rod 9 to rotate through the threaded rod 12 and the winding cylinder 5. When the rotating rod 9 rotates, the limiting post 11 is squeezed by the grooves on the inner wall of the placement groove 8, causing the limiting post 11 to move into the groove of the rotating rod 9. The spring 10 is compressed. When the rotating rod 9 rotates to the point where the limiting post 11 is facing the groove of the next placement groove 8, under the action of the spring 10, the end of the hemispherical structure of the limiting post 11 moves into the groove of the inner wall of the placement groove 8. In this way, the winding rod 4 can be limited to a certain angle.
[0032] One end of the winding rod 4 is fixedly connected to a threaded rod 12, which is threadedly connected to the inner wall of the winding cylinder 5. Rotating the winding rod 4 allows the threaded rod 12 to be screwed in or out of the threaded cylinder, which facilitates the support of the test gauge 1.
[0033] The limiting device includes a threaded ring 13, a movable ring 14, and multiple limiting brackets 15. The threaded ring 13 is threadedly fitted onto the sleeve 6, and the movable ring 14 is movably fitted onto the sleeve 6. The movable ring 14 is rotatably connected to the threaded ring 13. Multiple limiting brackets 15 are evenly and fixedly connected to the outer surface of the movable ring 14. A sliding block 16 is fixedly connected to the inner wall of the movable ring 14. The sliding block 16 can slide within a groove 17 opened on the side wall of the sleeve 6. The limiting bracket 15 has an L-shaped structure, and the inner side of the end of the L-shaped structure of the limiting bracket 15 is inclined. A rubber pad 18 is fixedly connected to the inner side of the limiting bracket 15. When storing the pointer 2, it rotates and winds... The rod 4 is brought into contact with the winding cylinder 5, and the cable is wound onto the sleeve 6 at the winding cylinder 5. Then, the threaded ring 13 is rotated. Since the sliding block 16 is fixedly connected to the moving ring 14 and the sliding block is limited in the groove 17, when the threaded ring 13 rotates, the moving ring 14 drives the limiting frame 15 to move downward, so that the cable wound around one turn is limited in the limiting frame 15. Then, the cable is continuously wound on the two sleeves 6. When the cable is wound to the bottom end of the sleeve 6 on the winding rod 4, the threaded ring 13 on it is rotated, so that the limiting frame 15 moves upward, limiting the cable wound around one turn, which is convenient for cable storage.
[0034] An anti-slip block 19 is fixedly connected to the end of the winding rod 4 away from the winding cylinder 5. The anti-slip block 19 has a hemispherical structure and is made of rubber.
[0035] The mounting base 3 is provided with two movable slots 20 for placing two test leads 2 respectively. Rubber strips 21 are fixedly connected to the two inner walls of the movable slots 20. Slots 22 are opened on the side walls of the two movable slots 20. The circular plates 23 at the ends of the test leads 2 can be moved into the slots 22. When the two test leads 2 are placed in the two movable slots 20, the test leads 2 squeeze the rubber strips 21, and the rubber strips 21 deform. After the test leads 2 are completely moved into the movable slots 20, the rubber strips 21 squeeze the test leads 2, thereby limiting the position of the test leads 2.
[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
