Description

Technical Field

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

[0002] Coaxial cable is a widely used wire and signal output line in fields such as communications, broadcasting, and computer networks. It is typically composed of multiple layers. In communications, coaxial cable is used to transmit high-frequency signals, such as television and network signals. In industry, it is used to connect various electronic devices and instruments. With the continuous development of technology, the application scenarios for coaxial cable are becoming increasingly widespread, and the requirements for its quality and performance are also becoming increasingly stringent.

[0003] Common cable testing devices can only perform sampling tests on cables, meaning that staff need to take samples of the cable to be tested and send them into the testing device for testing. The test data cannot represent the performance of the cable, and the cable needs to be moved manually during the testing process. It cannot be moved automatically. When the cable is very long, this not only increases the workload of the operator, but may also lead to inaccurate test results.

[0004] Therefore, there is an urgent need to provide a coaxial cable testing device to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a coaxial cable detection device.

[0006] To solve the above-mentioned technical problems, the present invention provides a coaxial cable testing device, including a testing box, with through holes on both sides of the testing box, and an operation display screen and an observation window installed at the front end of the testing box.

[0007] A servo motor is fixedly connected inside the detection box. A lead screw is fixedly connected to the output end of the servo motor. A sliding block is slidably connected to the outer wall of the lead screw. A clamping mechanism is provided at the bottom of the sliding block. A traction mechanism is provided inside the detection box. Multiple mounting plates are fixedly connected inside the detection box. Multiple ultrasonic transducers and signal receivers are fixedly connected to the other end of each of the multiple mounting plates.

[0008] The present invention is further configured such that: the clamping mechanism includes a fixed plate fixedly connected to the bottom of the sliding block, a first motor is installed on the top of the fixed plate, a rotating ring is fixedly connected to the output end of the first motor, two connecting strips are rotatably connected to the top of the rotating ring, two limiting grooves are opened on the top of the fixed plate, clamping blocks are slidably connected inside the two limiting grooves, and anti-slip strips are fixedly connected to the inner ends of the two clamping blocks.

[0009] With the above technical solution, in the initial state, the two clamping blocks are separated and do not clamp the cable. They can slide freely within the limiting groove, and their movement trajectory is restricted by the limiting groove. When it is necessary to clamp the cable, the first motor starts working and drives the rotating ring to rotate. Since the top of the rotating ring is connected to two connecting bars, the rotation of the rotating ring will drive the connecting bars to move. The other end of the connecting bars is connected to the clamping blocks. As the rotating ring rotates, the connecting bars push the two clamping blocks to slide relative to each other within the limiting groove. As the two clamping blocks slide inward, the distance between them gradually decreases. Due to the anti-slip strips at the inner end of the clamping blocks, when they come into contact with the cable, the anti-slip strips will increase the friction with the cable surface. Continued movement eventually clamps the cable between the two clamping blocks. The anti-slip strips achieve a firm clamping of the cable, preventing the cable from sliding in subsequent operations and ensuring the stability of the cable position.

[0010] The present invention is further configured such that the connecting strip is installed between the rotating ring and the clamping block.

[0011] Through the above technical solution, the connecting strip, as an intermediate connecting component, converts the rotational motion of the rotating ring into the linear motion of the clamping block, thereby improving the controllability and reliability of the motion.

[0012] The present invention is further configured such that: the inner end of the clamping block is provided with an arc-shaped clamping surface, and the arc-shaped clamping surface is in contact with the outer wall of the cable.

[0013] Through the above technical solution, the arc-shaped clamping surface can evenly distribute the clamping force in the circumferential direction of the cable, avoiding the situation of excessive or insufficient local force. This can ensure that the cable is subjected to balanced force in all directions, and prevent problems such as damage to the internal structure of the cable or indentation on the cable surface caused by uneven force.

[0014] The present invention is further configured such that: the traction mechanism includes two drive motors installed inside the detection box; multiple rotating wheels are rotatably connected inside the detection box; traction wheels are fixedly connected to the top of each of the multiple rotating wheels; and a transmission belt is installed between the multiple rotating wheels.

[0015] With the above technical solution, when the drive motor starts, the output shaft of the motor will rotate. When one of the rotating wheels rotates under the drive of the drive motor, due to the friction between the transmission belt and the rotating wheel, the rotating wheel will drive the transmission belt to move through the friction. The transmission belt will then drive other rotating wheels in contact with it to rotate, so that multiple rotating wheels can rotate synchronously or according to a certain transmission ratio. When the rotating wheel rotates, it will drive the traction wheel to rotate together. When the cable enters the traction mechanism, the cable will be pulled and moved by multiple traction wheels.

[0016] The present invention is further configured such that the drive motor is connected to one of the rotating wheels.

[0017] By using the above technical solution, the drive motor is directly connected to one of the rotating wheels, which can establish a clear power transmission path, reduce energy loss in intermediate links and possible transmission errors, and improve the efficiency of power transmission.

[0018] The present invention is further configured such that: a signal generator circuit board and a power amplifier are disposed inside the mounting plate, and the mounting plate and the operation display screen are electrically connected by wires.

[0019] Through the above technical solution, the signal generator circuit board is responsible for generating electrical signals of specific frequency and waveform, while the power amplifier can amplify these weak signals to give them sufficient power to drive subsequent testing equipment or test coaxial cables.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model designs a clamping mechanism and a component that drives the clamping mechanism to move. By starting the first motor, the movement of the two clamping blocks is controlled, thereby clamping cables of different sizes. Moreover, the operator does not need complicated operations to clamp the cables. They only need to insert the cables into the through holes. The operation is simple and greatly improves the applicability of the device.

[0022] 2. This utility model designs a traction mechanism and related detection components. When the cable is transported by the clamping mechanism and arrives inside the traction mechanism, multiple traction forces will pull the cable to move. At the same time as it moves, the detection components will perform a comprehensive inspection of the cable until the entire cable is inspected, thus avoiding missed inspections and preventing the cable from failing to meet quality standards.

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0031] Please see Figure 1 - Figure 3 A coaxial cable testing device includes a testing box 1. Both sides of the testing box 1 have through holes 2. The front end of the testing box 1 is equipped with an operation display screen 3 and an observation window 4. A servo motor 5 is fixedly connected inside the testing box 1. A lead screw 6 is fixedly connected to the output end of the servo motor 5. A sliding block 7 is slidably connected to the outer wall of the lead screw 6.

[0032] like Figure 4 and Figure 5 As shown, a clamping mechanism 8 is provided at the bottom of the sliding block 7. The clamping mechanism 8 includes a fixed plate 801 fixedly connected to the bottom of the sliding block 7. A first motor 802 is mounted on the top of the fixed plate 801. A rotating ring 803 is fixedly connected to the output end of the first motor 802. Two connecting strips 804 are rotatably connected to the top of the rotating ring 803. The connecting strips 804 are installed between the rotating ring 803 and the clamping block 806. The connecting strips 804 serve as intermediate connecting members, converting the rotational motion of the rotating ring 803 into the linear motion of the clamping block 806, thereby improving the controllability and reliability of the motion. The top of the fixed plate 801 has two limiting grooves 805, and the inside of each limiting groove 805 is slidably connected to a clamping block 806. The inner end of the clamping block 806 has an arc-shaped clamping surface, and the arc-shaped clamping surface is in contact with the outer wall of the cable. The arc-shaped clamping surface can evenly distribute the clamping force in the circumferential direction of the cable, avoiding the situation of excessive or insufficient local force. This can ensure that the cable is subjected to balanced force in all directions, and prevent problems such as damage to the internal structure of the cable or indentation on the surface of the cable due to uneven force. The inner ends of the two clamping blocks 806 are fixedly connected to anti-slip strips 807.

[0033] like Figure 4 and Figure 5As shown, in the initial state, the two clamping blocks 806 are separated and not clamping the cable. They can slide freely within the limiting groove 805, and their movement trajectory is restricted by the limiting groove 805. When it is necessary to clamp the cable, the first motor 802 starts working, driving the rotating ring 803 to rotate. Since the top of the rotating ring 803 is rotatably connected to two connecting bars 804, the rotation of the rotating ring 803 will drive the connecting bars 804 to move. The other end of the connecting bar 804 is connected to the clamping block 806. As the rotating ring 803 rotates, the connecting bar 804 pushes the two clamping blocks 806 to slide relative to each other within the limiting groove 805. As the two clamping blocks 806 slide inward, the distance between them gradually decreases. Due to the anti-slip strips 807 at the inner ends of the clamping blocks 806, when they come into contact with the cable, the anti-slip strips 807 will increase the friction with the surface of the cable. Continued movement eventually clamps the cable between the two clamping blocks 806. The anti-slip strips 807 achieve a firm clamping of the cable, preventing the cable from slipping in subsequent operations and ensuring the stability of the cable position.

[0034] like Figure 6 As shown, the testing box 1 is equipped with a traction mechanism 9. The traction mechanism 9 includes two drive motors 901 installed inside the testing box 1. Multiple rotating wheels 902 are rotatably connected inside the testing box 1. Each drive motor 901 is connected to one of the rotating wheels 902. The direct connection between the drive motor 901 and one of the rotating wheels 902 establishes a clear power transmission path, reduces energy loss in intermediate links and possible transmission errors, and improves the efficiency of power transmission. Traction wheels 903 are fixedly connected to the top of each of the multiple rotating wheels 902. A transmission belt 904 is installed between the multiple rotating wheels 902. When the drive motor 901 is driven to traction wheel 902, the traction wheel 903 is rotatably connected to the top of each of the multiple rotating wheels 902. When the drive motor 901 starts, the output shaft of the motor will rotate. When one of the rotating wheels 902 rotates under the drive of the drive motor 901, due to the friction between the transmission belt 904 and the rotating wheel 902, the rotating wheel 902 will drive the transmission belt 904 to move through the friction. The transmission belt 904 will then drive the other rotating wheels 902 in contact with it to rotate, so that multiple rotating wheels 902 can rotate synchronously or according to a certain transmission ratio. When the rotating wheel 902 rotates, it will drive the traction wheel 903 to rotate together. When the cable enters the traction mechanism 9, the cable will be pulled and moved by multiple traction wheels 903.

[0035] like Figure 3As shown, multiple mounting plates 10 are fixedly connected inside the testing box 1. The mounting plates 10 are equipped with signal generator circuit boards and power amplifiers. The mounting plates 10 are electrically connected to the operation display screen 3 through wires. The signal generator circuit board is responsible for generating electrical signals of specific frequencies and waveforms, while the power amplifier can amplify these weak signals to give them sufficient power to drive subsequent testing equipment or test coaxial cables. Multiple ultrasonic transducers 11 and signal receivers 12 are fixedly connected to the other end of the multiple mounting plates 10 respectively.

[0036] In use, the operator inserts the cable to be tested through the through hole 2 into the clamping mechanism 8. At this time, the first motor 802 starts working, driving the rotating ring 803 to rotate. As the rotating ring 803 rotates, the connecting bar 804 pushes the two clamping blocks 806 to slide relative to each other within the limiting groove 805 until the clamping blocks 806 clamp the cable. After the cable clamping is complete, the servo motor 5 starts running, driving the lead screw 6 to rotate, which in turn moves the sliding block 7 and the clamping mechanism 8. When the cable is transported to the edge of the traction mechanism 9, one end of the cable... The cable is positioned between two traction wheels 903, and the first motor 802 of the clamping mechanism 8 reverses to release the clamp on the cable. The traction mechanism 9 then pulls the cable to move. Two drive motors 901 drive multiple traction wheels 903 to rotate, thereby moving the cable. While the cable is moving, multiple ultrasonic transducers 11 surrounding the cable begin to perform ultrasonic testing on the cable and detect the internal wiring. The signal receiver 12 receives the signal and displays the detection results on the operation display screen 3. The operation of the traction mechanism 9 is used to detect the entire cable.

[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 description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
