Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to a voltage withstand tester for insulating tape. Background Technology

[0002] Insulating tape specifically refers to the tape used by electricians to prevent electrical leakage and provide insulation. Insulating tape possesses excellent insulation, voltage resistance, flame retardancy, and weather resistance properties, making it suitable for wire splicing, electrical insulation, and thermal protection. According to relevant national safety standards (GB19212.1, GB4943.1), insulating tape requires testing after production. The testing conditions involve wrapping the insulating tape 2-3 times, applying a 150N weight to the end of the tape, and then applying a voltage for one minute using a withstand voltage testing device. Therefore, a user-friendly testing frame needs to be designed for wrapping and applying the weight before testing. Utility Model Content

[0003] To solve the above-mentioned technical problems, this application provides a voltage withstand test frame for insulating tape, including a base, a counterweight, a clamp connected to the counterweight, and two support rods disposed on both sides of the base. Bearing seats are respectively disposed on the two support rods. The bearing seats are adjustablely mounted on the support rods. A rotating shaft passes through the two bearing seats. A rotating component for driving the rotating shaft is disposed on the side of one of the bearing seats.

[0004] Preferably, a triangular winding block is inserted through the center of the rotating shaft. The winding block is used to wind insulating tape, and columnar iron blocks are spaced apart on one side of the winding block.

[0005] Preferably, mounting holes arranged along the height direction are provided on the side of the support rod, and the bearing seat is connected to the mounting holes by a locking member.

[0006] Preferably, the support rod has a clearance groove that extends along its height direction.

[0007] Preferably, the rotating assembly includes a mounting plate disposed on the side of the bearing housing, and a rotating rod connected to the end of the rotating shaft is disposed on the mounting plate.

[0008] Preferably, a positioning pin is inserted through the rotating rod, and a plurality of positioning holes arranged in a ring array are provided on the mounting plate.

[0009] Preferably, the clamping block includes two clamping plates and fasteners for locking the two clamping plates, a hook ring is provided at the bottom of one of the clamping plates, and a hook rod that cooperates with the hook ring is provided at the top of the counterweight block.

[0010] As can be seen from the above, the following beneficial effects can be obtained by applying the method provided in this application: By setting two support rods on both sides of the base, and setting bearing seats on the two support rods respectively, the bearing seats are adjustable in height on the support rods. A rotating shaft passes through the two bearing seats, and a rotating component for driving the rotating shaft is set on the side of one of the bearing seats. After one end of the insulating tape is connected to the rotating shaft, the rotating component drives the rotating shaft to rotate, so that the insulating tape is wound around the rotating shaft several times. The other end of the insulating tape is clamped by a clamping block, and then the insulating tape is straightened and tightly wound around the rotating shaft under the action of a counterweight, thus realizing the winding and load-bearing of the insulating tape. Then, the withstand voltage testing equipment tests the insulating tape, improving the testing efficiency and accuracy. Attached Figure Description

[0013] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. Example

[0014] To solve the above-mentioned technical problems, this embodiment provides a voltage withstand test frame for insulating tape, used to fix the insulating tape to be tested, and applied to the voltage withstand test equipment of insulating tape, as shown in Figure 1. It includes a base 10, a counterweight 70, a clamping block 60 connected to the counterweight 70, and two support rods 20 arranged on both sides of the base 10. Bearing seats 30 are respectively arranged on the two support rods 20. The bearing seats 30 are adjustablely arranged on the support rods 20. A rotating shaft 40 passes through the two bearing seats 30. A rotating component 50 for driving the rotating shaft 40 to rotate is arranged on the side of one of the bearing seats 30. After one end of the insulating tape is connected to the rotating shaft 40, the rotating assembly 50 drives the rotating shaft 40 to rotate, causing the insulating tape to wrap around the rotating shaft 40 several times. The other end of the insulating tape is then clamped by the clamping block 60, and under the action of the counterweight block 70, the insulating tape is straightened and tightly wound onto the rotating shaft 40, thus achieving the winding and load-bearing of the insulating tape. The withstand voltage testing equipment then tests the insulating tape, improving testing efficiency and accuracy.

[0015] Specifically, a triangular winding block 41, a conductive metal block, is inserted through the center of the rotating shaft 40. The winding block 41 is used to wind the insulating tape. Cylindrical iron blocks 42 are spaced apart on one side of the winding block 41, serving as a limiting element during tape winding. One end of the insulating tape to be tested is attached to the winding block 41. The rotating assembly 50 drives the rotating shaft 40 to rotate two revolutions, causing the insulating tape to wind onto the winding block 41. In some embodiments, after the insulating tape is installed, an iron block is placed on the insulating tape on the top surface of the winding block 41. One connector of the withstand voltage tester is connected to the cylindrical iron block 42, and the other connector is connected to the iron block. A voltage is then applied to test whether the insulating tape will be broken down. If it is broken down, the iron block and the winding block 41 will make contact and conduct electricity, allowing the withstand voltage tester to determine whether the insulating tape is qualified.

[0016] Furthermore, mounting holes 21 arranged along the height direction are provided on the side of the support rod 20. The bearing seat 30 is connected to the mounting holes 21 through locking members 31, so that the installation height of the bearing seat 30 can be adjusted according to actual needs. The support rod 20 has a clearance groove 22 extending along its height direction. When adjusting the installation height of the bearing seat 30, the clearance groove 22 prevents the rotating shaft 40 from moving, thus allowing the rotating shaft 40 to move up and down with the bearing seat 30 to complete the position adjustment.

[0017] Furthermore, the rotating assembly 50 includes a mounting plate 51 screwed onto the side of the bearing housing 30. A rotating rod 52 connected to the end of the rotating shaft 40 is mounted on the mounting plate 51. The rotating rod 52 is rotatably mounted on the mounting plate 51 via bearings, and its end is fixedly connected to the end of the rotating shaft 40. Rotating the rotating rod 52 drives the rotating shaft 40 to rotate, which in turn drives the winding block 41 to rotate, thus winding the insulating tape. The rotating rod 52 and the rotating shaft 40 can be made of insulating material to improve safety.

[0018] Furthermore, to fix the rotating rod 52, a positioning pin 54 is inserted through the rotating rod 52. A plurality of positioning holes 53 arranged in a ring array are provided on the mounting plate 51. The rotating rod 52 and the rotating shaft 40 are fixed by inserting the positioning pin 54 into the positioning holes 53, thereby preventing the rotating shaft 40 from rotating during testing. For example, in some embodiments, there may be 8 or 12 positioning holes 53. Furthermore, when winding the insulating tape, the position of the positioning pin 54 in conjunction with the positioning holes 53 allows for accurate setting of the number of turns, such as 2 turns, 2.5 turns, 3 turns, etc. This allows for accurate winding of a specified number of turns according to the test conditions of different types of insulating tape, improving compatibility and test accuracy.

[0019] Furthermore, such as Figure 2 As shown, the clamping block 60 includes two clamping plates 61 and fasteners 62 for locking the two clamping plates 61. A hook ring 63 is provided at the bottom of one of the clamping plates 61. The two clamping plates 61 are locked by the fasteners 62, thereby clamping and fixing the end of the insulating tape. The counterweight block 70 is provided with a hook rod 71 that cooperates with the hook ring 63 at the top, thereby enabling the tape to bear the load.

[0020] In summary, this application's solution involves setting two support rods on both sides of the base, with bearing seats mounted on each rod. These bearing seats are adjustable in height. A rotating shaft passes through both bearing seats, and a rotating assembly for driving the rotating shaft is located on the side of one of the bearing seats. One end of the insulating tape is connected to the rotating shaft, and the rotating assembly drives the shaft to rotate, causing the insulating tape to wrap around the shaft several times. The other end of the insulating tape is then clamped by a clamping block, and under the action of a counterweight, the insulating tape is straightened and tightly wound onto the rotating shaft. This achieves the winding and load-bearing of the insulating tape, allowing the withstand voltage testing equipment to test the tape, thus improving testing efficiency and accuracy.

[0021] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
