Description
Technical Field
[0001] This utility model relates to the field of cable line testing technology, specifically a cable line collision testing device. Background Technology
[0002] Cable lines typically consist of three parts: insulated conductors, protective layers, and outer sheaths. They are commonly used in cable systems to transmit power, communication signals, or data. Cable lines can be used in various applications, including residential and commercial buildings, industrial facilities, and communication networks, and have a wide range of uses.
[0003] When conducting collision tests on cables, existing cable collision testing devices primarily use a fixed frame. A slide rail is mounted on the top of the fixed frame, and a collision head is slidably installed inside the slide rail. Gear discs are symmetrically mounted at both ends of the inner side of the fixed frame, with chains fitted onto the gear discs. One end of the collision head is fixedly connected to the chain. A drive motor is fixed to the side of the fixed frame, and its output is fixedly connected to the gear discs. The testing device is then mounted on the test cable via the fixed frame. The drive motor rotates one side of the gear disc, causing the chain to slide the collision head inside the slide rail, resulting in the collision head striking the cable surface. By observing the collision location, the test result can be determined. After the test, the collision head can be reset for the next test. This structure is simple to operate and convenient to use.
[0004] However, the shape of the collision structure in the current testing device cannot be changed during use, and it cannot detect the collision results of different collision structures under the same collision force. This results in a single detection result and a small scope of application. Therefore, a cable line collision testing device is proposed. Utility Model Content
[0005] To overcome the shortcomings of existing technologies, the collision structure shape of commercially available testing devices cannot be changed during use, making it impossible to detect the collision results of cables with different collision structures under the same collision force. This results in the detection structure having a single detection result and a limited scope of application. Therefore, this utility model proposes a cable line collision testing device.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The cable line collision test device of this utility model includes a bracket; a test mechanism is provided on the side of the bracket, a positioning mechanism is provided at one end of the test mechanism, a fixing mechanism is provided on the inner side of the bracket, and a mounting base is movably fixed on the side of the bracket.
[0007] Preferably, the testing mechanism includes a mounting base, a shaft fixed inside the mounting base, a rotating seat rotatably mounted inside the mounting base, a fixing plate fixed at the center of the rotating seat, torsion springs fixedly connected to both sides of the fixing plate and the mounting base, a straight plate fixed on the circumference of the rotating seat, a fixing seat at one end of the straight plate, a connecting seat fastened inside the fixing seat, a collision head fixed at one end of the connecting seat, a limit rod inserted between the fixing seat and the connecting seat, a large gear at one end of the rotating seat, a servo motor fixed on the side of the mounting base, a small gear fixed through the output end of the servo motor, the small gear meshing with the large gear, and the connecting seat and the fixing seat fixedly connected by the limit rod. The structure is simple and easy to assemble and disassemble, allowing for replacement of the collision head as needed, ensuring more accurate test results.
[0008] Preferably, the positioning mechanism includes a rotating seat with positioning holes evenly distributed on one side. A rod is slidably inserted through the top side of the mounting base. A limit cap is fixed to one end of the rod, and a spring is fixedly connected between the limit cap and the mounting base. The spring is fitted onto the rod. One end of the rod is fastened to the inside of the positioning hole. The bracket has symmetrical inner clamps at both ends. Through the structure of the rod and the positioning hole, the rotating seat can be precisely rotated to the required angle, thereby realizing the function of adjusting the collision force and making the testing device more widely applicable.
[0009] Preferably, the fixing mechanism includes an inner clamping plate with screws inserted at both ends of the inner clamping plate and rotatably connected to the inner clamping plate. One end of each screw has a rectangular groove. An outer clamping plate is fastened to the side of the inner clamping plate, and threaded holes are provided at both ends of the outer clamping plate. The screws on both sides are rotatably installed inside the threaded holes. The clamping plates are fixed to the cable by the screws, so that the testing device can test cables in any environment and is more convenient for operators to use.
[0010] The advantages of this utility model are:
[0011] 1. This utility model, through the structural design of a cable line collision testing device, sets up a testing mechanism, selects a collision head of the desired shape, and attaches its top connecting seat through a straight plate to the inside of a fixed seat. Then, a limiting rod is inserted into the inside of the connecting seat and the fixed seat. At this time, a servo motor can be controlled to drive the rotating seat to rotate, causing the torsion spring to be stretched. Then, the servo motor is turned off, and the torsion spring drives the rotating seat to reset through its elastic force, causing the collision head to strike the cable surface, thereby performing a collision test. This solves the problems of complex structure and single test results of existing testing devices.
[0012] 2. This utility model, through the structural design of a cable line collision testing device, uses a positioning mechanism to pull out the insertion rod by pulling the limiting cap, releasing the fixation on the rotating seat. The rotating seat is then rotated to the desired positioning hole, the limiting cap is released, and the insertion rod is re-inserted into the desired positioning hole by a spring, fixing the rotating seat at the required collision force. When a collision test is needed, the insertion rod can be pulled out in the same way to perform the test. The collision force can be adjusted by changing the rotation angle of the rotating seat, making the testing device more convenient and applicable to a wider range of situations.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0021] See also Figure 1-4 As shown, a cable line collision testing device includes a bracket 1; a testing mechanism is provided on the side of the bracket 1, a positioning mechanism is provided at one end of the testing mechanism, a fixing mechanism is provided on the inner side of the bracket 1, and a mounting base 2 is movably fixed on the side of the bracket 1.
[0022] See also Figure 2 As shown, the testing mechanism includes a mounting base 2, a shaft 3 fixed inside the mounting base 2, a rotating seat 4 rotatably mounted inside the mounting base 2, a fixing plate 5 fixed at the center of the inner side of the rotating seat 4, torsion springs 6 fixedly connected between the fixing plate 5 and the mounting base 2 on both sides, a straight plate 10 fixed on the circumference of the rotating seat 4, a fixing seat 13 provided at one end of the straight plate 10, a connecting seat 11 fastened inside the fixing seat 13, a collision head 12 fixed at one end of the connecting seat 11, a limit rod 14 inserted between the fixing seat 13 and the connecting seat 11, a large gear 7 provided at one end of the rotating seat 4, a servo motor 8 fixed on the side of the mounting base 2, a small gear 9 fixed through the mounting base 2 at the output end of the servo motor 8, and the small gear 9 meshing with the large gear 7. When encountering problems with the complex structure and inconvenience of existing testing devices during operation, the required shape of the impact head 12 is selected based on the structure of the testing mechanism. The top connecting seat 11 is passed through the straight plate 10 and fastened to the inside of the fixed seat 13. Then, the limiting rod 14 is inserted into the inside of the connecting seat 11 and the fixed seat 13. At this time, the servo motor 8 can be controlled to drive the output pinion 9 to rotate. With the cooperation of the large gear 7, the rotating seat 4 is driven to rotate around the shaft 3, so that the torsion spring 6 is stretched. At this time, the servo motor 8 is turned off, and the torsion spring 6 drives the rotating seat 4 to reset through its elastic force, causing the impact head 12 at one end of the straight plate 10 to strike the cable surface inside the bracket 1, thereby performing an impact test. This testing device has a simple structure and the impact head 12 can be replaced at any time, making it more convenient for operators to use.
[0023] See also Figure 3As shown, the positioning mechanism includes a rotating seat 4, with positioning holes 18 evenly distributed on one side. A rod 15 is slidably inserted through the top side of the mounting base 2. A limit cap 16 is fixed to one end of the rod 15. A spring 17 is fixedly connected between the limit cap 16 and the mounting base 2, and the spring 17 is fitted onto the rod 15. One end of the rod 15 is fastened to the inside of the positioning hole 18. The bracket 1 has symmetrical inner clamping plates 19 at both ends. During operation, when encountering the problem of inaccurate adjustment of the collision force during collision testing, the positioning mechanism's structure... Pull the limit cap 16 to pull the insertion rod 15 out from the inside of the positioning hole 18, thereby releasing the fixation on the rotating seat 4. At this time, the straight plate 10 can be rotated to rotate the rotating seat 4 to the required positioning hole 18. Release the limit cap 16, and pull the insertion rod 15 back into the required positioning hole 18 through the spring 17, fixing the rotating seat 4 at the required impact force. When the impact test is required, the insertion rod 15 can be pulled out in the same way to carry out the test. The impact force can be adjusted by changing the rotation angle of the rotating seat 4, making the testing device more convenient for testing and with a wider range of applications.
[0024] See also Figure 4 As shown, the fixing mechanism includes an inner clamping plate 19, with screws 20 inserted at both ends of the inner clamping plate 19 and rotatably connected to the inner clamping plate 19. One end of each screw 20 has a rectangular groove 21. An outer clamping plate 22 is fastened to the side of the inner clamping plate 19, and threaded holes 23 are opened at both ends of the outer clamping plate 22. The screws 20 on both sides are rotatably installed inside the threaded holes 23. During operation, when encountering the problem that the existing collision testing device has a complex structure and is inconvenient to install and test, the fixing mechanism, with the cooperation of the inner clamping plate 19, fastens the bracket 1 at the cable testing position. At this time, the outer clamping plate 22 is fastened to one side of the inner clamping plate 19, so that one end of the screw 20 is fastened inside the threaded hole 23. Then, with the cooperation of the rectangular groove 21, the screw 20 is rotated, causing it to move the outer clamping plate 22 towards the inner clamping plate 19, clamping and fixing the bracket 1 at the cable testing position, thereby facilitating subsequent collision testing.
[0025] See also Figure 5 As shown, the inner clamping plate 19 and the inner clamping surface of the outer clamping plate 22 are fixed with anti-slip ribs 24. During operation, when the test device falls off due to the smooth surface of the cable, the structure of the anti-slip ribs 24 increases the friction between the clamping plate and the cable clamping surface when the inner clamping plate 19 and the outer clamping plate 22 are clamped and fixed on the cable, thereby preventing the test device from loosening and falling off.
[0026] Working Principle: Cable lines typically consist of three parts: insulated conductors, protective layers, and outer sheaths. They are commonly used in cable systems for transmitting power, communication signals, or data. Cable lines can be used in various applications, including residential and commercial buildings, industrial facilities, and communication networks. However, existing testing devices cannot change the shape of their collision structure, making it impossible to detect the collision results of cables with different shapes under the same collision force. This results in limited detection results and a narrow range of applications. To address this issue, a testing mechanism and a positioning mechanism are incorporated. With the cooperation of the inner clamping plate 19, the bracket 1 is fastened to the cable testing position. At this time, the outer clamping plate 22 is fastened to one side of the inner clamping plate 19, and one end of the screw 20 is fastened inside the threaded hole 23. Then, with the cooperation of the rectangular groove 21, the screw 20 is rotated, causing the outer clamping plate 22 to move towards the inner clamping plate 19, clamping and fixing the bracket 1 at the cable testing position. Pulling the limit cap 16 causes the insertion rod 15 to be pulled out from inside the positioning hole 18, thereby releasing the fixation on the rotating seat 4. The controllable servo motor 8 drives the output pinion 9 to rotate. With the cooperation of the large gear 7, the rotating seat 4 rotates around the shaft 3, causing the torsion spring 6 to be tightened. At this time, the rotating seat 4 is located at the required positioning hole 18. Then, the limit cap 16 is released, and the spring 17 pulls the insertion rod 15 to re-insert it into the inside of the required positioning hole 18, fixing the rotating seat 4 at the required impact force. At the same time, the servo motor 8 is turned off. When the impact test is required, the impact head 12 of the required shape is selected, and its top connecting seat 11 is passed through the straight plate 10. Installed inside the fixed base 13, the limiting rod 14 is then inserted into the connecting base 11 and the fixed base 13 to fix the collision head 12. Similarly, the insertion rod 15 is pulled out. At this time, the torsion spring 6 drives the rotating base 4 to reset through its elastic force, causing the collision head 12 at one end of the straight plate 10 to strike the cable surface inside the bracket 1, thereby conducting a collision test. The force of the collision can be adjusted by changing the rotation angle of the rotating base 4, making the testing device easier to use and the test results more accurate. This solves the problem of complex structure and single test results of existing testing devices.
