Description

Technical Field

[0001] This invention relates to the field of network device testing, and in particular to an embedded network fault diagnosis device. Background Technology

[0002] An embedded network fault diagnosis device is an integrated network monitoring and fault analysis equipment. Employing an embedded system architecture, it highly integrates hardware circuitry, operating system, diagnostic software, and communication modules into a compact device. By acquiring network data packets in real time, monitoring network traffic, and analyzing protocol communication status and device operating parameters, this device can automatically identify anomalies such as connection failures, protocol errors, performance bottlenecks, and security threats in the network. It then uses built-in diagnostic algorithms to locate faults and analyze their causes. Compared to traditional PC-based network diagnostic tools, embedded network fault diagnosis devices offer advantages such as small size, low power consumption, high reliability, strong environmental adaptability, and long-term online monitoring capabilities. They are suitable for applications with high requirements for device size and stability, such as industrial control networks, smart grids, IoT systems, and vehicle networks. They enable continuous monitoring of network health status and rapid fault diagnosis and response, significantly improving the operational efficiency and reliability of network systems.

[0003] Existing network fault diagnosis equipment mainly falls into three categories: hardware testing equipment, network analysis software, and professional monitoring systems. Hardware equipment includes cable testers, cable locators, optical power meters, digital voltmeters, time domain reflectometers (TDRs), tone generators and tone locators, and hardware feedback devices, used to detect physical layer cable connectivity issues, fiber optic attenuation, cable open circuits, short circuits, and other hardware faults. Software tools include protocol analysis tools like Wireshark, packet capture tools like tcpdump, network connectivity testing commands like Ping and Traceroute, domain name resolution tools like Nslookup, and network performance monitoring platforms such as SolarWinds Network Performance Monitor, Nagios, PRTG Network Monitor, Zabbix, and Cacti.

[0004] Traditional network fault diagnosis equipment is often placed directly on a workbench for operation, with its bottom flush against the surface. However, in actual operation, this installation method, where the bottom is flush against the workbench, affects the heat dissipation of the network fault diagnosis equipment, leading to excessively high temperatures. This, in turn, affects the equipment's performance and lifespan. High temperatures can also affect the stability of embedded network detection. Furthermore, placing the equipment directly on the workbench makes it less stable during use, making it susceptible to external impacts that can cause displacement, resulting in loose wiring and disrupting normal operation.

[0005] Therefore, an embedded network fault diagnosis device is proposed to solve the above problems. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide an embedded network fault diagnosis device, which has the advantages of overhead installation, good heat dissipation, stable installation and applicability to network fault diagnosis equipment of different sizes.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0008] An embedded network fault diagnosis device includes a heat dissipation mechanism;

[0009] The heat dissipation mechanism includes a mounting base, and two sets of overhead limiting mechanisms are mounted on the upper surface of the mounting base. The network fault diagnosis equipment body is mounted between the two sets of overhead limiting mechanisms.

[0010] The mounting base has two mounting slots on its upper surface, and a cooling fan is installed in each of the two mounting slots.

[0011] Both sets of the overhead limiting mechanism include a positioning seat and a positioning plate mounted on the upper surface of the mounting base. Two positive and negative threaded rods are rotatably provided between the positioning seat and the positioning plate. The two positive and negative threaded rods are arranged in parallel and four nut bushings are engaged with their external parts.

[0012] The two nut bushings that mesh in the same direction are jointly fitted with clamping seats on their outer sides, and the main body of the network fault diagnosis equipment is supported on the upper end face of the four clamping seats in the two sets of overhead limit mechanisms.

[0013] Furthermore, each of the four clamping seats has a clamping plate vertically mounted on its upper surface, and the clamping plate has anti-slip textures on its side. The network fault diagnosis device body is disposed between the four clamping plates and is in contact with the side of the clamping plates.

[0014] Furthermore, the mounting base is also provided with several air inlet slots, which are distributed around the cooling fan.

[0015] Furthermore, the positioning seats in both sets of the overhead limiting mechanisms are equipped with bearing seats on their sides, and a gear shaft is rotatably installed inside the bearing seats.

[0016] Furthermore, two rotating shafts are also installed on the side of the positioning seat, and each of the two rotating shafts is rotatably equipped with a mating wheel shaft.

[0017] Furthermore, the two mating wheel shafts and the gear shaft are arranged in a triangular shape and are externally meshed and tensioned with a transmission belt; one end of the gear shaft passes through a bearing housing and is connected to a handle.

[0018] In summary, the present invention has the following beneficial effects:

[0019] 1. This embedded network fault diagnosis device achieves the dual functions of efficient heat dissipation and stable support through the innovative design of the heat dissipation mechanism. The cooling fans installed in the two mounting slots on the upper surface of the mounting base, together with several through-hole air inlets, form a complete forced convection heat dissipation system. The layout of the air inlets surrounding the cooling fans ensures sufficient and uniform air intake. After external cold air is drawn in from multiple directions from the bottom of the mounting base, it is blown upwards to the bottom of the network fault diagnosis device body by the cooling fans, effectively reducing the operating temperature of the device.

[0020] 2. Two sets of overhead limit mechanisms allow the network fault diagnosis equipment body to be supported on the upper surfaces of the four clamping seats, forming a gap between the upper surface of the mounting base and the upper surface of the clamping seat. This provides ample space for heat dissipation airflow, significantly improving heat dissipation efficiency and equipment operational stability. Furthermore, through the positive and negative threaded screw mechanism in conjunction with the transmission belt, the clamping width can be precisely and synchronously adjusted, adapting to network fault diagnosis equipment bodies of different sizes. The overall structure significantly improves the adaptability, fixation reliability, and ease of operation of the equipment installation. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0028] First embodiment;

[0029] Reference Figure 1-4 As shown, an embedded network fault diagnosis device according to a preferred embodiment of the present invention includes a heat dissipation mechanism 10.

[0030] The heat dissipation mechanism 10 includes a mounting base 1, and two sets of overhead limit mechanisms 3 are mounted on the upper surface of the mounting base 1. The network fault diagnosis equipment body 4 is mounted between the two sets of overhead limit mechanisms 3.

[0031] The mounting base 1 has two mounting slots 12 on its upper surface, and a cooling fan 2 is installed in each of the two mounting slots 12.

[0032] Both sets of overhead limiting mechanisms 3 include a positioning seat 31 and a positioning plate 32 mounted on the upper surface of the mounting base 1. Two positive and negative threaded rods 33 are rotatably provided between the positioning seat 31 and the positioning plate 32. The two positive and negative threaded rods 33 are arranged in parallel and four nut bushings 34 are meshed on their exterior.

[0033] Two nut bushings 34 with the same tooth direction are fitted with clamping seats 35 on their outside. The network fault diagnosis equipment body 4 is supported on the upper end face of the four clamping seats 35 set in the two sets of overhead limit mechanisms 3.

[0034] In this embodiment, the embedded network fault diagnosis device achieves the dual functions of efficient heat dissipation and stable support through the innovative design of the heat dissipation mechanism 10. The cooling fans 2 installed in the two mounting slots 12 on the upper surface of the mounting base 1, together with the several through-hole air inlet slots 11, form a complete forced convection heat dissipation system. The layout of the air inlet slots 11 surrounding the cooling fans 2 ensures sufficient and uniform air intake. After external cold air is drawn in from multiple directions from the bottom of the mounting base 1, it is blown upward to the bottom of the network fault diagnosis device body 4 by the cooling fans 2, effectively reducing the operating temperature of the device. The two sets of overhead limiting mechanisms 3, through the coordinated cooperation of the positioning seat 31, positioning plate 32, positive and negative threaded rods 33, nut bushing 34 and clamping seat 35, enable the network fault diagnosis device body 4 to be supported on the upper surface of the four clamping seats 35 and form an overhead space gap with the upper surface of the mounting base 1, providing sufficient channel space for heat dissipation airflow, significantly improving heat dissipation efficiency and device operating stability.

[0035] Furthermore, the device achieves precise synchronous adjustment of the clamping width through the transmission system of the forward and reverse threaded rods 33 and the transmission belt 310. When the operator turns the handle 311, the gear shaft 38 drives the transmission belt 310 through the rotation within the bearing housing 37. The transmission belt 310, the two mating wheel shafts 391, and the gear shaft 38 are triangularly distributed and meshed, ensuring stable power transmission. The two mating wheel shafts 391 rotate synchronously on the rotating shaft 39 and drive the two forward and reverse threaded rods 33. The forward and reverse tooth design allows the four nut bushings 34 and their four clamping seats 35 to achieve symmetrical tightening or loosening, adapting to different sizes of network fault diagnosis equipment body 4; the clamping plates 36 vertically set on the upper surface of the four clamping seats 35 have anti-slip textures on their sides, and the network fault diagnosis equipment body 4 is set between the four clamping plates 36 and fits tightly against their sides. The anti-slip textures effectively enhance the friction and prevent the equipment from shifting due to vibration or external force. The overall structure significantly improves the adaptability, fixation reliability and ease of operation of the equipment installation.

[0036] Second embodiment;

[0037] Reference Figure 3-4 As shown, each of the four clamping seats 35 has a clamping plate 36 vertically mounted on its upper surface. The clamping plate 36 has anti-slip textures on its side. The network fault diagnosis device body 4 is positioned between the four clamping plates 36 and fits against the side of the clamping plate 36.

[0038] In this embodiment, each of the four clamping seats 35 has a vertically mounted clamping plate 36 on its upper surface. The sides of the clamping plates 36 are provided with anti-slip textures to enhance friction and contact stability with the device body. The network fault diagnosis device body 4 is positioned between the four clamping plates 36 and fits against the sides of the clamping plates 36. The device body 4 is secured from all sides through four-sided clamping. The anti-slip textures effectively prevent displacement of the device due to vibration or external impact during operation, ensuring device stability and wiring reliability.

[0039] Third embodiment;

[0040] Reference Figure 1-2 As shown, the mounting base 1 is also provided with several air inlet slots 11, which are distributed around the cooling fan 2.

[0041] In this embodiment, the mounting base 1 is also provided with several air inlet slots 11, which are distributed around the cooling fan 2 to form a reasonable air intake channel layout. This design allows external cold air to enter evenly from multiple directions at the bottom of the mounting base 1. After the cooling fan 2 draws in the cold air through the air inlet slots 11, it blows the air upwards to the bottom of the network fault diagnosis device body 4, achieving forced convection cooling, effectively reducing the operating temperature of the device, and improving the heat dissipation efficiency and uniformity.

[0042] Fourth embodiment;

[0043] Reference Figure 3-4 As shown, the positioning seats 31 in both sets of overhead limit mechanisms 3 are equipped with bearing seats 37 on their sides, and a gear shaft 38 is rotatably installed inside the bearing seats 37.

[0044] In this embodiment, the positioning seats 31 in both sets of overhead limiting mechanisms 3 are equipped with bearing seats 37 on their sides. A gear shaft 38 is rotatably mounted inside the bearing seat 37, providing a power input interface for the clamping width adjustment mechanism. The bearing seat 37 ensures the rotational accuracy and stability of the gear shaft 38, reduces rotational friction resistance, and allows the operator to smoothly perform clamping width adjustment operations, achieving adaptability to network fault diagnosis equipment bodies 4 of different sizes.

[0045] Fifth embodiment;

[0046] Reference Figure 3-4 As shown, two rotating shafts 39 are also installed on the side of the positioning seat 31, and a mating wheel shaft 391 is rotatably provided on the outside of each of the two rotating shafts 39.

[0047] In this embodiment, two rotating shafts 39 are also installed on the side of the positioning seat 31. Each of the two rotating shafts 39 has a mating wheel shaft 391 rotatably mounted on its exterior, forming the driven part of the transmission system. The rotation of the mating wheel shaft 391 on the rotating shaft 39 creates conditions for power transmission. Through its cooperation with the gear shaft 38, the transmission function is realized, effectively transmitting the rotational motion of the gear shaft 38 to the forward and reverse threaded rods 33, and completing the synchronous symmetrical adjustment action of the clamping seat 35.

[0048] Sixth embodiment;

[0049] Reference Figure 3-4 As shown, the two mating wheel shafts 391 and the gear shaft 38 are arranged in a triangular shape and are connected to the transmission belt 310 by meshing on their exteriors; one end of the gear shaft 38 passes through the bearing seat 37 and is connected to a handle 311.

[0050] In this embodiment, two mating wheel shafts 391 and gear shaft 38 are arranged in a triangular shape and are externally meshed and tensioned with a transmission belt 310, forming a stable and reliable belt drive system. One end of the gear shaft 38 passes through the bearing housing 37 and is connected to a handle 311, providing a convenient manual operation interface for the operator. When the operator turns the handle 311, the gear shaft 38 drives the transmission belt 310 to rotate, and the transmission belt 310 synchronously drives the two mating wheel shafts 391 to rotate, thereby driving the positive and negative threaded rods 33 to rotate, realizing the synchronous and symmetrical adjustment of the four clamping seats 35. The complete transmission chain design ensures the synchronicity, accuracy and reliability of the adjustment operation.

[0051] Specific implementation process

[0052] Step 1: First, place the network fault diagnosis device body 4 between the two sets of overhead limiting mechanisms 3 on the upper surface of the mounting base 1, so that the device body 4 is supported on the upper surface of the four clamping seats 35 and fits against the sides of the four clamping plates 36. The anti-slip texture on the side of the clamping plates 36 ensures the stable positioning of the device. At this time, an overhead gap is formed between the network fault diagnosis device body 4 and the upper surface of the mounting base 1, which creates conditions for heat dissipation. After the power is turned on, the cooling fan 2 in the two mounting slots 12 on the upper surface of the mounting base 1 starts to work. External air is drawn in through several air inlet slots 11 that are opened through the mounting base 1. These air inlet slots 11 are distributed around the cooling fan 2 to ensure sufficient air intake. The cooling fan 2 blows the cold air upward to the bottom of the network fault diagnosis device body 4 to achieve forced convection heat dissipation.

[0053] Step 2: When it is necessary to adjust the clamping width to fit the network fault diagnosis equipment body 4 of different sizes, the operator turns the handle 311. The handle 311 drives the gear shaft 38 connected to it to rotate in the bearing seat 37. The rotation of the gear shaft 38 transmits power to the two mating wheel shafts 391 through the transmission belt 310. Since the gear shaft 38 and the two mating wheel shafts 391 are arranged in a triangular shape and mesh together to tension the transmission belt 310, a stable transmission system is formed. The two mating wheel shafts 391 are respectively rotatably arranged outside the two rotating shafts 39. When the mating wheel shafts 391 rotate, they drive the positive and negative threaded rods 33 connected to them to rotate synchronously. The two positive and negative threaded rods 33 are arranged in parallel and have four nut bushings 34 meshing on their exterior.

[0054] Step 3: Since the two lead screws 33 adopt a forward and reverse thread design, when the screws rotate, the two nut bushings 34 with the same thread direction will move in the same direction, while the two nut bushings 34 with opposite thread directions will move in opposite directions, realizing the symmetrical adjustment of the four nut bushings 34; the two nut bushings 34 with the same thread direction are jointly fitted with a clamping seat 35, so the four clamping seats 35 will simultaneously perform symmetrical tightening or loosening actions; through the stable support between the positioning seat 31 and the positioning plate 32, and the coordinated cooperation of the two sets of overhead limit mechanisms 3, the distance between the four clamping seats 35 can be precisely adjusted, so that the clamping plate 36 is tightly attached to the side of the network fault diagnosis equipment body 4, realizing the stable clamping and precise positioning of the equipment, while maintaining the overhead state of the bottom of the equipment, ensuring that the airflow generated by the cooling fan 2 can effectively pass through the bottom of the equipment, realizing a continuous forced cooling effect.
