Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, and in particular to a cable testing device. Background Technology

[0002] Cables are a type of large-diameter, long-length equipment used to transmit electrical energy. They are usually not replaced or maintained for a long time after installation. Therefore, various tests are required for cables, including electrical performance testing, insulation performance testing, appearance inspection, and mechanical performance testing.

[0003] Existing cable testing equipment, such as the cable testing equipment disclosed in CN222336946U, consists of a support rod, a turning block, a tension gauge, and a clamping device. It can effectively detect the stress at the bending point of the cable. However, the method of clamping and fixing the cable end with a clamp and bolt is relatively loose. Especially during the tensile test, the continuously increasing tensile force can pull the cable end out of the clamping device, causing the test to be interrupted and the test results to be inaccurate. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the existing method of clamping and fixing the cable ends with clamps and bolts is too loose, especially during tensile testing, where the continuously increasing tensile force can pull the cable ends out of the clamping device, causing the test to be interrupted and the test results to be inaccurate. Therefore, a cable testing device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable testing device includes a support rod and a limiting plate disposed on the support rod. A rectangular sleeve is fixedly connected to one end of the support rod away from the rotating shaft. A rotating wheel for winding cables is disposed inside the rectangular sleeve. A clamping structure is disposed on the outer wall of the rotating wheel. A clamping rod is connected to the rotating wheel through the clamping structure. An internal hexagonal hole is formed on the outer wall of the rotating wheel. A flip door is connected to one side of the open end of the rectangular sleeve through a hinge. A limiting block is disposed on the flip door and is inserted into the internal hexagonal hole.

[0007] Preferably, the clamping structure includes a socket, a limiting groove, a clamping plate, and a spring. The socket is disposed on the outer wall of the rotating wheel, the limiting groove is disposed on the upper and lower sides of the inner wall of the socket, the clamping plate is slidably connected to the limiting groove, and one end of the spring is fixedly connected to the inner wall on the right side of the socket.

[0008] Preferably, the insertion port completely penetrates the outer wall of the rotating wheel, the clamping plate is slidably connected to the inner wall of the insertion port, the other end of the spring is fixedly connected to the right wall of the clamping plate, and the clamping rod abuts against the clamping plate.

[0009] Preferably, the clamping plate has a guide ramp on the side facing the open end, and the guide ramp faces the clamping rod.

[0010] Preferably, the outer wall of the rectangular sleeve has uniformly distributed through holes on the back, through which the clamping rod can pass.

[0011] Preferably, a handle is provided on one end of the rotating wheel facing the opening, and a stop is provided on one end of the clamping rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In use, this invention utilizes a rotating wheel, an internal hexagonal hole, a limiting block, a clamping rod, and a clamping structure. First, the cable is wound around the rotating wheel. After several turns, the cable coil and end are clamped between the rotating wheel and the clamping rod. Then, the rotating wheel is rotated, and the limiting block and internal hexagonal hole are used to fix the rotating wheel, preventing it from rotating on its own. This method of fixing the cable by clamping the end and winding the cable results in a more compact cable fixation, more stable testing, and more accurate test results. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-5 A cable testing device includes a support rod 1 and a limiting plate 2 disposed on the support rod 1. A rectangular sleeve 3 is fixedly connected to one end of the support rod 1 away from the rotating shaft. A rotating wheel 4 for winding cables is disposed inside the rectangular sleeve 3. A clamping structure is disposed on the outer wall of the rotating wheel 4. A clamping rod 6 is connected to the rotating wheel 4 through the clamping structure. An internal hexagonal hole 5 is opened on the outer wall of the rotating wheel 4. A flip door 7 is connected to one side of the open end of the rectangular sleeve 3 through a hinge. A limiting block 8 is disposed on the flip door 7 and is inserted into the internal hexagonal hole 5.

[0022] It should be noted that the support rod 1 and the limiting plate 2 are existing technologies in the prior art. The specific model and specifications to be used need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0023] Furthermore, the clamping structure includes a socket 9, a limiting groove 10, a clamping plate 11, and a spring 12. The socket 9 is disposed on the outer wall of the rotating wheel 4, the limiting groove 10 is disposed on the upper and lower sides of the inner wall of the socket 9, the clamping plate 11 is slidably connected to the limiting groove 10, and one end of the spring 12 is fixedly connected to the inner wall of the socket 9.

[0024] The clamping structure is designed to secure the cable coil and wire end wound on the rotating wheel 4 with the clamping rod 6, preventing them from easily loosening.

[0025] Furthermore, the socket 9 completely penetrates the outer wall of the rotating wheel 4, the clamping plate 11 is slidably connected to the inner wall of the socket 9, the other end of the spring 12 is fixedly connected to the outer wall of the clamping plate 11, and the clamping rod 6 abuts against the clamping plate 11.

[0026] The spring 12 moves the clamping plate 11 toward the shaft of the rotating wheel 4, thereby clamping the clamping rod 6 in the socket 9.

[0027] Furthermore, a guide ramp 13 is provided on the side of the clamping plate 11 facing the open end, and the guide ramp 13 faces the clamping rod 6.

[0028] The guide ramp 13 makes it easier to insert the clamping rod 6 without having to manually move the clamping plate 11, making it more convenient to use.

[0029] Furthermore, the outer wall of the rectangular sleeve 3 has evenly distributed through holes 14 on the back, through which the clamping rod 6 can pass.

[0030] Inserting the clamping rod 6 into the through hole 14 can prevent the rotation of the rotating wheel 4, further enhancing the fixing effect of the rotating wheel 4.

[0031] Furthermore, a handle 15 is provided on one end of the rotating wheel 4 facing the opening, and a stop block 16 is provided on one end of the clamping rod 6.

[0032] The rotary handle 15 allows the wheel 4 to be rotated manually, and the stop block 16 makes it easier to insert and remove the clamping rod 6 without slipping.

[0033] Working principle: When it is necessary to clamp and fix one end of the cable, first, open the flip door 7, then manually pull the cable end through the limit plate 2 and place it on the rotating wheel 4. Then, pass the clamping rod 6 through the guide ramp 13 and clamping plate 11 on the socket 9 and clamp the cable end between the clamping rod 6 and the rotating wheel 4. Then, rotate the rotating wheel 4 by the handle 15 to make the cable wrap around the rotating wheel 4. After wrapping it more than three times, fix the end of the clamping rod 6 without the stop block 16 through the through hole 14. Then close the flip door 7 and insert the limit block 8 on the flip door 7 into the internal hexagon hole 5. This completes the fixing of the cable.
