Technical Field

[0001] This invention relates to a tester, and more specifically to a network tester. Background Technology

[0002] A network tester, also known as a professional network tester or network detector, is a portable, visual, intelligent testing device that can detect the operational status of the physical layer, data link layer, and network layer as defined by the OSI model. It is primarily used for local area network (LAN) fault detection, maintenance, and structured cabling construction. The functions of a network tester cover the physical layer, data link layer, and network layer. For example, patent number CN216051989U, entitled "A Portable Network Tester," discloses a design that allows for easier carrying of the network tester. However, existing solutions only test the network itself, performing checks on the integrity of the network cable. Summary of the Invention

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] like Figures 1 to 11 As shown, in order to solve the technical problem of "how to inspect the appearance of different types of network cables", the structure and function of a network tester will be described in detail below;

[0035] A network tester includes a support ring I 11, with support rings II 12 fixedly connected to both the front and rear sides of the support ring I 11, and support rings III 13 fixedly connected to the outer sides of both support rings II 12.

[0036] Each support ring Ⅲ13 is rotatably connected to a clamping cylinder 21, a clamping plate 22 is fixedly connected to the clamping cylinder 21, a threaded plate 23 is rotatably connected to the clamping cylinder 21, and multiple clamping brackets 24 are slidably connected to the clamping plate 22. Each clamping bracket 24 is rotatably connected to a clamping wheel 25.

[0037] A power mechanism I for driving the clamping cylinder 21 to rotate is fixedly connected to the support ring Ⅲ13. The power mechanism I is preferably a servo motor.

[0038] A power mechanism II for driving the threaded disc 23 to rotate is fixedly connected to the clamping cylinder 21. The power mechanism II is preferably a servo motor.

[0039] A power mechanism Ⅲ for driving the clamping wheel 25 to rotate is fixedly connected to the clamping bracket 24. The power mechanism Ⅲ is preferably a servo motor.

[0040] In use, place the network cable to be tested between the two clamping discs 22 on the front and rear sides, start the power mechanism II, and the output shaft of the power mechanism II will start to rotate. The output shaft of the power mechanism II will drive the threaded disc 23 to rotate. When the threaded disc 23 rotates, it will drive multiple clamping brackets 24 to move through the threads, so that the multiple clamping brackets 24 move closer or further away from each other. The multiple clamping brackets 24 will drive multiple clamping wheels 25 to move, so that the multiple clamping wheels 25 move closer to each other to clamp the network cable.

[0041] Furthermore, the clamping wheel 25 is covered with an elastic jacket made of rubber, which gives the clamping wheel 25 a certain deformation capability. When the length and width of the network cable are not the same, multiple clamping wheels 25 can clamp the network cable even when they are close to each other at equal distances.

[0042] Furthermore, the power mechanism III is activated, and the output shaft of the power mechanism III begins to rotate. The output shaft of the power mechanism III drives the clamping wheel 25 to rotate. The clamping wheel 25 contacts the network cable, and when the clamping wheel 25 rotates, it pushes the network cable to move, so that the network cable continuously passes through the detection head 53, thereby detecting the network cable.

[0043] Furthermore, the rotation speed of the clamping wheel 25 located on the front side is greater than that of the clamping wheel 25 located on the rear side, so that when the network cable passes through the detection head 53, the pulling action generated by the clamping wheel 25 on the front side makes the network cable straight, ensuring the accuracy of the detection head 53.

[0044] Furthermore, the power mechanism I is activated, and the output shaft of the power mechanism I begins to rotate. The output shaft of the power mechanism I drives the clamping cylinder 21 to rotate, the clamping cylinder 21 drives the clamping plate 22 to rotate, the clamping plate 22 drives multiple clamping brackets 24 to move, and the clamping brackets 24 drive the clamping wheels 25 to move, thereby adjusting the position of the multiple clamping wheels 25 and thus adjusting the clamping position of the clamping wheels 25 on the network cable to meet different usage requirements.

[0045] A rotating ring 31 is rotatably connected to the support ring II12, and a power mechanism IV that drives the rotating ring 31 to rotate is fixedly connected to the support ring II12. The power mechanism IV is preferably a servo motor.

[0046] Four telescopic mechanisms I41 are fixedly connected to the support ring I11. Each telescopic mechanism I41 has a limit frame 42 fixedly connected to its telescopic end. Two adjacent limit frames 42 are slidably connected to each other.

[0047] The four limiting frames 42 constitute the limiting track;

[0048] Multiple sliding brackets 51 are slidably connected between the two rotating rings 31. A compression spring I is fixedly connected between the sliding bracket 51 and the rotating ring 31. A limiting rail can limit the movement of the sliding bracket 51. A telescopic mechanism II 52 is fixedly connected to the sliding bracket 51. A detection head 53 is fixedly connected to the telescopic end of the telescopic mechanism II 52.

[0049] A sensor 54 is fixedly connected inside the detection head 53. A ball-encased cavity 55 is slidably connected inside the detection head 53. A compression spring II is fixedly connected between the ball-encased cavity 55 and the detection head 53. A detection ball 56 is fitted onto the ball-encased cavity 55 with a clearance fit. The ball-encased cavity 55 can contact the sensor 54.

[0050] Since network cables come in different shapes, with circular and rectangular cross-sections, the following sections will explain in detail how to test network cables with circular and rectangular cross-sections, respectively.

[0051] When the cross-section of the network cable is circular, the telescopic mechanism I41 is activated. The telescopic mechanism I41 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I41 drives the limiting frame 42 to move, thereby moving the four limiting frames 42 away from each other, so that the limiting track formed by the four limiting frames 42 cannot contact the sliding bracket 51, and thus the limiting track cannot limit the sliding bracket 51. Then the telescopic mechanism II52 is activated. The telescopic mechanism II52 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II52 drives the detection head 53 to move, and the detection head 53 drives the detection ball 56 to move, so that the detection ball 56 contacts the network cable. The detection ball 56 pushes the covering ball cavity 55 to contact the sensor 54. The sensor 54 is preferably a pressure sensor. Thus, when the covering ball cavity 55 contacts the sensor 54, the covering ball cavity 55 generates a squeezing force on the sensor 54.

[0052] When the power mechanism IV is activated, its output shaft begins to rotate. This rotation drives the rotating ring 31 to rotate, which in turn drives the detection head 53 to rotate around the network cable. Simultaneously, the network cable continuously passes through the detection head 53, and the detection ball 56 contacts the surface of the network cable. When the surface of the network cable is damaged, the detection ball 56 falls into the damaged area and covers the ball cavity 55, thus no longer squeezing the sensor 54. The sensor 54 is no longer squeezed and transmits a signal, indicating that there is damage to the network cable at this location.

[0053] When the cross-section of the network cable is rectangular, the telescopic mechanism I41 is activated. The telescopic mechanism I41 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I41 drives the limiting frame 42 to move, and then the four limiting frames 42 move closer to each other, so that the limiting track formed by the four limiting frames 42 can contact the sliding bracket 51. Then the limiting track can limit the sliding bracket 51. The length and width of the limiting track formed by the four limiting frames 42 are set according to the shape of the network cable to be detected. The limiting track limits the sliding bracket 51, so that the detection ball 56 contacts the network cable. The detection ball 56 pushes the covering ball cavity 55 to contact the sensor 54. The sensor 54 is preferably a pressure sensor. Then when the covering ball cavity 55 contacts the sensor 54, the covering ball cavity 55 generates a squeezing force on the sensor 54.

[0054] When the power mechanism IV is activated, its output shaft begins to rotate. This rotation drives the rotating ring 31 to rotate, which in turn drives the detection head 53 to rotate around the network cable. Simultaneously, the network cable continuously passes through the detection head 53, and the detection ball 56 contacts the surface of the network cable. When the surface of the network cable is damaged, the detection ball 56 falls into the damaged area and covers the ball cavity 55, thus no longer squeezing the sensor 54. The sensor 54 is no longer squeezed and transmits a signal, indicating that there is damage to the network cable at this location.
