The two vertically stacked interface modules 6 are connected to each other through the quick-plug connector 62, and the interface module 6 is connected to the detection box 2 through the quick-plug connector 62, and the controller 10 is connected to the interface module 6 through the quick-plug interface 61.

[0041] The T-shaped partition 73 is used to divide the inner cavity of the shunt pipe 72 into two left and right chambers, and the vertical flat tube 74 is inserted into the shell 5 and passes through the top of the shell 5. The fin 21 is installed directly above the vertical flat tube 74 through the detection box 2 and the frame 1.

[0042] The wind flow plate 93 is fixedly connected to the second flat tube 91, and the joint ring 94 passes through the second flat tube 91 and is connected with the air inlet 92. The second flat tube 91 is docked and installed with the first flat tube 71 through the joint ring 94 and the diverter tube 72. The vertical flat tube 2 95 is connected to the frame box 4. The second flat tube 91 is installed in parallel with the cooling fan 15 through the vertical flat tube 2 95 and the frame box 4, and the air inlet 92 vertically corresponds to the bottom of the cooling fan 15. The side of the special-shaped air duct 96 close to the air inlet 92 is expanded, and the side away from the air inlet 92 is contracted, and the cross-section of the special-shaped air duct 96 is an eight-shaped shape. The frame box 4 is connected with the vertical flat tube 2 95 through the special-shaped air duct 96.

[0043] When in use, the two interface modules 6 are fitted together to form a pair of interface modules 6, and then a positioning frame 8 is placed at the bottom of the pair of interface modules 6. Under the structural condition that a vertical flat tube 74 is inserted at the four corners of the inner side of the shell 5, the positioning frame 8 is limited and locked at the bottom of the inner side of the shell 5 by using the vertical flat tube 74; then the pair of interface modules 6 are embedded and installed inside the positioning frame 8, and then the second positioning frame 8 is stacked on top of the pair of interface modules 6 under the guidance of the four vertical flat tubes 74, and then another pair of interface modules 6 are embedded and installed inside the second positioning frame 8, so that the quick plug-in connector at the top of the first pair of interface modules 6 The head 62 is inserted into the middle part of the bottom of the second pair of interface modules 6, and then the third positioning frame 8 is installed on the top of the second pair of interface modules 6, and the third positioning frame 8 is stacked on the top of the second pair of interface modules 6; then the detection box 2 is inserted into the center of the top of the rack 1 by aligning the pins 17 and the card holes 20, so that the detection box 2 is horizontally inserted as a whole in the middle position of the top of the rack 1. At the same time, the middle position of the bottom of the detection box 2 is plugged into the quick plug-in connector 62 on the top of the second pair of interface modules 6, so as to complete the electrical connection between the four interface modules 6 and the detection box 2, and the results detected by the four interface modules 6 can be displayed in time through the four display screens 3 installed on the top of the detection box 2.

[0044] Then, a first isolation frame 16 is embedded and installed at the bottom inner side of the frame box 4, and then a controller 10 is horizontally stacked on top of the first installed isolation frame 16, and the controller 10 is pushed toward the position where the shell 5 is located, so that the output end of the controller 10 corresponds to the quick plug-in interface 61 and is quickly plugged into the interface module 6, and then a second isolation frame 16 is stacked on top of the first controller 10, so that the isolation frame 16 is horizontally embedded and installed on the inner side of the frame box 4, and a controller 10 is stacked on top of the second isolation frame 16. This controller 10 is the second controller 10. At this time, the same operation is used to plug the controller 10 with another interface module 6 to complete the quick plug-in of the two controllers 10 with the two interface modules 6, and then the structural layout of the inner side of the second frame box 4 on the other side of the shell 5 is the same as the above structural layout, thereby completing the quick plug-in of the third and fourth controllers 10 with the interface module 6; at this time, the detection results of the four controllers 10 are displayed in time by the display screen 3, thereby realizing the simultaneous detection of the four controllers 10 by the detection equipment.

[0045] Through the above operations, the interface module 6, positioning frame 8, controller 10 and isolation frame 16 are arranged and installed during the first use of the detection equipment. In the subsequent detection operation, the manual disassembly space provided by the notch 161 can be used to manually pinch the middle part of the tail of the controller 10 and directly unplug the four controllers 10 from the interface module 6, keeping the positioning frame 8 and the isolation frame 16 in their respective corresponding frame structures. The horizontal guide track provided by the isolation frame 16 can be used to horizontally guide the subsequent controllers 10 to ensure that the controllers 10 can be accurately plugged into the quick-plug interfaces 61 on each interface module 6, so that the number of controllers 10 detected each time is four groups, so that the detection equipment can quickly plug and detect four groups of controllers 10 at the same time, improving the inefficient state that traditional detection equipment can only detect one or two controllers 10, and improving the number and efficiency of controllers 10 that the detection equipment can detect.

[0046] By assembling four interface modules 6 in pairs, they are limitedly installed on the inner side of the shell 5 with the help of the positioning frame 8, and at the same time, the detection box 2 is vertically inserted on the top of the rack 1 through the pin 17 to realize the convenient assembly of the detection box 2 and the interface module 6 on the rack 1. Even if the models of the controllers 10 to be detected are different, individual interface modules 6 can be replaced in time to complete the modular upgrade and update of the local structure of the detection equipment, so as to adapt to the simultaneous detection of controllers of different models by the detection equipment; and even if individual interface modules 6 are damaged, the new interface modules 6 can be quickly disassembled and replaced by simple plug-in and unplug actions, so as to ensure the efficient operation of the detection equipment and improve the detection efficiency of the detection equipment.

[0047] During the detection of the controller 10, the cooling liquid circulation pump 12 and the cooling fan 15 can be activated to directly dissipate heat and cool the inside of the frame box 4 through the cooling fan 15. At the same time, the cooling liquid circulation pump 12 is combined with the cooling liquid circulation pipe 13 to circulate the coolant between the two heat sinks 14 embedded on the inner wall of the frame box 4. The heat sink 14 is used to circulate and cool the air inside the frame box 4, and the heat generated by the controller 10 when being detected inside the frame box 4 is quickly guided and dissipated in time, thereby realizing multi-directional heat dissipation and cooling of the heat inside the frame box 4.

[0048] When the cooling fan 15 is activated, the air outlet of the cooling fan 15 can be arranged correspondingly to the position of the air inlet 92 to guide part of the airflow into the second flat tube 91, and the airflow can be divided into three streams under the diversion and guiding effect of the air flow plate 93 and the joint ring 94 on the airflow, and respectively led to the vertical flat tube 2 95 at the two ends of the second flat tube 91, and the third airflow is diverted and guided again to the vertical flat tube 1 74 at the two ends of the first flat tube 71 through the diversion tube 72 and the T-shaped partition 73 installed inside the T-shaped partition 73 of the diversion tube 72, and the airflow is vertically guided out from the top of the frame box 4 and the shell 5 respectively through the vertical flat tube 2 95 and the vertical flat tube 1 74. During this period, the Bernoulli principle can be used to pass through the vertical flat tube 2 95 and the vertical flat tube 1 74. The special-shaped air ducts 96, which are all embedded and installed, guide the hot air flow inside the frame box 4 and the shell 5 into the corresponding vertical flat tube structures, and are ejected from the top of the rack 1 together with the air flow vertically guided by the vertical flat tube structures, thereby realizing auxiliary guidance and cooling treatment of the hot air flow inside the frame box 4 and the shell 5, and can guide the hot air flow hidden between the positioning frame 8 and the isolation frame 16. At the same time, the vertical flat tube 2 95 and the vertical flat tube 1 74 are respectively arranged at the embedded installation positions at the inner corners of the frame box 4 and the shell 5 in their respective corresponding structures to actively dissipate the heat accumulated in the corners of the frame box 4 and the shell 5, so as to avoid the phenomenon of local overheating and damage of the controller caused by the long-term accumulation of heat at the four corners of the inner side of the frame box 4 and the shell 5.

[0049] At the same time, the airflow can also be blown from the vicinity of the fins 21 to assist in cooling the entirety of the test box 2, thereby avoiding overheating of the test box 2 that is in a test state for a long time, and ensuring that the test box 2 is within a safe operating temperature range. At the same time, the airflow can also blow the air around the test box 2 to speed up the flow rate of the airflow near the test box 2, further helping the test box 2 to dissipate heat and cool itself, and at the same time, it can also blow away foreign matter and dust to avoid accumulation and obstruction of foreign matter and dust on the display screen 3, thereby protecting the display screen 3 and allowing the test results displayed on the surface of the display screen 3 to be clearly observed.

[0050] By guiding and utilizing the airflow driven by the cooling fan 15 through the above-mentioned guide pipe rack 7 and drainage pipe rack 9, not only can the auxiliary evacuation and cooling guidance of the airflow inside the frame box 4 and the shell 5 be achieved, but also the cooling and protection of the structure on the top of the rack 1: the detection box 2 and the display screen 3 can be achieved, and the detection equipment can achieve multi-directional cooling and heat dissipation functions for various parts of itself while maintaining energy consumption. While saving resources, it gives the detection equipment a green and energy-saving environmental protection function.

[0051] By installing a positioning frame 8 between each stacked interface module 6 and an isolation frame 16 between each stacked controller 10, the interface modules 6 can be effectively isolated from each other, and the top and bottom of each layer of controller 10 can be isolated, providing effective heat dissipation and air flow space for the interface modules 6 and the controllers 10 to avoid a large amount of heat accumulation inside these structures. At the same time, it ensures that the internal structures of the detection equipment maintain a smooth ventilation and heat dissipation state, so that even if the above-mentioned coolant circulation pump 12 and coolant circulation pump 12 are not activated, they can ensure the normal operation of the detection equipment in a short time, so that the detection equipment can be used under different working conditions.

At the same time, the closed chamber formed by the rectangular groove 114 in front of the side wall plate of the frame box 4 can be used to temporarily store and retain the excess cold air generated by the heat sink 14, thereby auxiliary cooling and cooling the corresponding part of the rectangular groove 114 on the top of the inner side of the frame box 4, thereby realizing multi-directional cooling treatment of the frame box 4 and reducing the possibility of heat accumulation on the inner side of the frame box 4.

A shrink head 175 is telescopically connected to the middle of the shrink tube 174. A spring 176 is connected between the shrink tube 174 and the spring piece 172, and the spring 176 is sleeved on the surface of the shrink head 175. The spring piece 172 is elastically installed with the pin 17 through the shrink head 175 and the spring 176.

[0055] When in use, the pin 17 is pressed down corresponding to the card hole 20 and inserted into the top of the frame 1. During this period, the spring piece 172 is squeezed toward the shrink tube 174, and the two ends of the spring piece 172 shrink toward the inside of the side opening 171, the shrink head 175 is squeezed back into the shrink tube 174, and the spring 176 is compressed. When the pin 17 is completely inserted into the card hole 20, the spring piece 172 will be released from the side opening 171 under the rebound action of the spring 176, and the spring 176 that rebounds the spring piece 172 drives the shrink head 175 to extend out of the shrink tube 174. At this time, the pin 17 is clamped on the inner side of the card hole 20 through the spring piece 172. At this time, the smooth and simple insertion of the detection box 2 on the top of the frame 1 is completed.

[0056] When the pin 17 needs to be pulled out of the hole 20, the detection box 2 can be directly pulled upward to squeeze the spring piece 172 to quickly pull the pin 17 out of the hole 20. At this time, the detection box 2 is disassembled from the top of the rack 1, and the interface module 6 can be exposed to the operator's field of vision, thereby realizing the replacement or upgrade of individual interface modules 6, so that the detection equipment can keep up with the progress of technology and carry out modular iterative upgrades and uses according to different detection needs, and will not be limited by the structure of the equipment itself and unable to keep up with the update and use of technology.

[0057] Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments.
