Description

Technical Field

[0001] This utility model relates to the technical field of continuity testing, specifically to a continuity testing device. Background Technology

[0002] Continuity testing is one of the essential electrical performance tests for power filters. The purpose of continuity testing is to detect whether a line of the power filter is properly connected from the input to the output, and whether there is any disconnection between lines or between a line and the casing.

[0003] Currently, most power-on / off testing devices typically use a cylinder to move a probe to contact the power filter for testing. However, the cylinder is usually fixed to the device, which has the following drawbacks: the position of the cylinder cannot be adjusted, making the device unable to adapt to the testing requirements of power filters of different heights, thus reducing the flexibility and practicality of the device. Utility Model Content

[0004] The purpose of this invention is to provide a power-on / off testing device to solve the problem that the inability to adjust the position of the cylinder makes the device unable to adapt to the testing requirements of power filters at different heights, thereby reducing the flexibility and practicality of the device.

[0005] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a power on / off testing device, comprising a support plate, the support plate being fixed to the top surface of a base, a mounting frame being slidably provided on the outer wall of the support plate, a cylinder being fixed inside the mounting frame, one end of the cylinder telescopic rod penetrating the inner bottom surface of the mounting frame, a moving block being fixed to one end of the cylinder telescopic rod, a plurality of probes being fixed to the bottom surface of the moving block, a placement seat being detachably provided above the base, and first threaded holes being opened on the left and right sides of the outer wall of the mounting frame, with first screws threadedly connected to the two first threaded holes respectively, and rotating rods being fixed to the outer walls of the two first screws respectively.

[0006] Preferably, the front side of the support plate is provided with a sliding groove, and the rear side of the mounting bracket is fixed with a slider, which is slidably disposed in the sliding groove.

[0007] Preferably, the top surface of the base is movably provided with a movable plate, the top surface of the base is fixed with two second screws, the top surface of the movable plate is provided with two movable holes, the two second screws are respectively located in the two movable holes, and the threaded ends of the two second screws are respectively threaded with nuts.

[0008] Preferably, the top surface of the movable plate is provided with a plurality of first threaded grooves, and the top surface of the placement seat is provided with a plurality of second threaded holes. Each of the plurality of second threaded holes is threaded with a first bolt, and the threaded ends of the plurality of first bolts are respectively threaded with the interior of the plurality of first threaded grooves.

[0009] Preferably, the front side of the movable block is detachably provided with a protective frame.

[0010] Preferably, the front side of the movable block has two second threaded grooves, and the front side of the protective frame has two third threaded holes. The two third threaded holes are respectively threaded with second bolts, and the threaded ends of the two second bolts are respectively threaded with the interior threads of the two second threaded grooves.

[0011] Compared with existing technologies, the power-on / off testing device that adopts the above technical solution has the following advantages:

[0012] In operation, the operator first places the power filter to be tested inside the mounting base. Then, the cylinder is activated to move the moving block downwards, causing the probe at the bottom of the moving block to descend and precisely align with the test interface of the power filter, initiating the continuity test. When testing power filters at different heights, rotating the rotating rod causes the first screw to rotate, gradually loosening its contact with the support plate. At this point, the mounting bracket can slide freely along the support plate to adjust to the desired height. After adjustment, rotating the rotating rod in the opposite direction causes the first screw to firmly press against the support plate, securing the mounting bracket and ensuring stability during the test. The coordinated use of the support plate, mounting bracket, cylinder, moving block, probe, mounting base, first threaded hole, first screw, and rotating rod facilitates continuity testing of power filters and allows for adjustment of the mounting bracket and cylinder height, adapting to the testing needs of power filters at different heights and improving the flexibility and practicality of the device.

[0013] Second, during use, the combination of the sliding groove and the slider allows the operator to limit the height of the mounting bracket, preventing it from shaking or shifting, thus improving stability during adjustment. The combination of the moving plate, the second screw, and the nut allows the operator to move the moving plate freely along the length of the movable hole. By tightening the nut, the moving plate can be securely fixed in the desired position, and the mounting base can be adjusted back and forth accordingly to meet different testing needs.

[0014] Thirdly, during use, the cooperation of the first threaded groove, the second threaded hole, and the first bolt facilitates the disassembly and assembly of the placement seat, thereby simplifying maintenance or replacement and improving the convenience and efficiency of maintenance. The protective frame is made of transparent material, which neither obstructs the observation of the testing process nor prevents accidental contact during testing, ensuring testing safety. The cooperation of the second threaded groove, the third threaded hole, and the second bolt facilitates the disassembly and assembly of the protective frame, thereby simplifying maintenance or replacement and improving the reliability and durability of the device.

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, a power-on / off testing device includes a support plate 1, which is fixed to the top surface of a base 2. A mounting frame 3 is slidably mounted on the outer wall of the support plate 1. A cylinder 4 is fixed inside the mounting frame 3. One end of the telescopic rod of the cylinder 4 passes through the bottom surface of the mounting frame 3. A moving block 5 is fixed to one end of the telescopic rod of the cylinder 4. Several probes 6 are fixed to the bottom surface of the moving block 5. A placement seat 7 is detachably mounted on the top of the base 2. First threaded holes 8 are opened on the left and right sides of the outer wall of the mounting frame 3. First screws 9 are threaded into the two first threaded holes 8 respectively. Rotating rods 10 are fixed to the outer walls of the two first screws 9 respectively.

[0022] In use, the operator first places the power filter to be tested inside the mounting base 7. Then, the cylinder 4 is activated, causing the moving block 5 to move downwards. The probe 6 at the bottom of the moving block 5 descends accordingly, precisely engaging with the test interface of the power filter to begin the power-on / off test. When power filters of different heights need to be tested, the rotating rod 10 is rotated, and the first screw 9 rotates accordingly, gradually loosening its contact with the support plate 1. At this time, the mounting bracket 3 can slide freely along the support plate 1 to adjust to the required height. After adjustment, the rotating rod 10 is rotated in the opposite direction, and the first screw 9 tightly abuts against the support plate 1, securing the mounting bracket 3 firmly and ensuring stability during the test. The coordinated use of the support plate 1, mounting bracket 3, cylinder 4, moving block 5, probe 6, mounting base 7, first threaded hole 8, first screw 9, and rotating rod 10 facilitates the power-on / off test of the power filter and allows adjustment of the height of the mounting bracket 3 and cylinder 4, adapting to the testing needs of power filters of different heights and improving the flexibility and practicality of the device.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, a sliding groove 11 is provided on the front side of the support plate 1, and a slider 12 is fixed on the rear side of the mounting bracket 3. The slider 12 is slidably disposed in the sliding groove 11.

[0024] In use, the cooperation of the slide groove 11 and the slider 12 helps the staff to limit the height of the mounting bracket 3 when adjusting it, preventing it from shaking or shifting, thereby improving the stability during adjustment.

[0025] like Figures 1-3 As shown, a movable plate 13 is movably mounted on the top surface of the base 2. Two second screws 14 are fixed on the top surface of the base 2. Two movable holes 15 are opened on the top surface of the movable plate 13. The two second screws 14 are respectively located in the two movable holes 15. Nuts 16 are threadedly connected to the threaded ends of the two second screws 14. Several first threaded grooves 17 are opened on the top surface of the movable plate 13. Several second threaded holes 18 are opened on the top surface of the placement seat 7. First bolts 19 are threadedly connected to the several second threaded holes 18. The threaded ends of the several first bolts 19 are respectively threadedly connected to the interior of the several first threaded grooves 17.

[0026] In use, the movable plate 13, the second screw 14, and the nut 16 work together to allow operators to move the movable plate 13 freely along the length of the movable hole 15. Tightening the nut 16 secures the movable plate 13 to the desired position, and the placement seat 7 adjusts accordingly to meet different testing needs. The first threaded groove 17, the second threaded hole 18, and the first bolt 19 facilitate the disassembly and assembly of the placement seat 7, enabling maintenance or replacement and improving convenience and efficiency.

[0027] like Figure 1 and Figure 2 As shown, a protective frame 20 is detachably provided on the front side of the movable block 5. Two second threaded grooves 21 are opened on the front side of the movable block 5, and two third threaded holes 22 are opened on the front side of the protective frame 20. Two second bolts 23 are threadedly connected in the two third threaded holes 22 respectively, and the threaded ends of the two second bolts 23 are respectively threadedly connected to the inside of the two second threaded grooves 21.

[0028] During use, the protective frame 20 is made of transparent material, which not only does not obstruct the observation of the testing process but also effectively prevents accidental contact during the test, ensuring testing safety. The cooperation of the second threaded groove 21, the third threaded hole 22, and the second bolt 23 facilitates the disassembly and assembly of the protective frame 20 by the staff, thereby making it easier to maintain or replace the protective frame 20 and improving the reliability and durability of the device.
