[0034] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1 , Figure 2 and Figure 3As shown, to achieve the above objectives, this utility model provides an integrated electro-analysis fixture suitable for in vitro diagnostic instruments, comprising: a movable frame 1 and a power supply box 2, a power distribution box 3, a control component 4, and an industrial control board 5 disposed within the movable frame 1.

Moreover, the various shapes and functions of the plug interfaces 7 set on the outer shell 106 can adapt to the corresponding modules to be tested, quickly completing the electrical testing requirements of different instrument modules, eliminating the need for multiple electrical testing fixtures, and making it more convenient to use.

[0040] It should be noted that two omnidirectional wheels and two directional wheels with locking function are provided on the bottom surface of the base plate 101, which facilitates the movement and storage of the integrated electrical testing fixture, making it more convenient for testing instrument modules located in different locations. In addition, a handle 6 is provided on the outer side of the outer shell 106, which makes it easy for operators to push and pull the integrated electrical testing fixture.

[0041] In some embodiments of this utility model, a circuit board bracket 10 is provided in the second installation area, which separates the second installation area into a certain space.

[0044] In some embodiments of this utility model, a first ventilation port is provided inside the first housing 201, a first fan 208 is provided at the location of the first ventilation port, and a first heat dissipation hole 209 is provided on the other side of the first housing 201. Specifically, the first fan 208 and the first ventilation port are provided on opposite sides of the first housing 201. The first fan 208 draws out the air with a higher temperature inside the first housing 201, and the air with a lower temperature outside the first housing 201 enters the first housing 201 through the first heat dissipation hole 209, so that an air circulation effect is formed inside the first housing 201, which effectively reduces the temperature inside the first housing 201 and provides a certain degree of protection for the power supply 202.

[0045] It should be noted that a first side plate 210 is provided on one side of the first housing 201. The first side plate 210 is connected to the first housing 201 by several screws. By making the first side plate 210 detachable, it is convenient to repair and replace electronic components such as the power supply 202 inside the first housing 201 in the future.

Specifically, the second fan 304 and the second ventilation port are disposed on opposite sides of the second box 301. The second fan 304 draws out the air with a higher temperature inside the second box 301, and the air with a lower temperature outside the second box 301 enters the second box 301 through the second heat dissipation hole 305, so that an air circulation effect is formed inside the second box 301, which effectively reduces the temperature inside the second box 301 and provides a certain degree of protection for the two power distribution boards 302.

[0047] It should be noted that a second side plate 303 is provided on one side of the second enclosure 301. The second side plate 303 is connected to the second enclosure 301 by several screws. By making the second side plate 303 detachable, it is convenient to repair and replace electronic components such as the power distribution board 302 inside the second enclosure 301 in the future.

[0048] In some embodiments of this utility model, each connector 7 is provided with a silkscreen mark (not shown in the figure) below it. The silkscreen mark can help staff quickly and accurately find the corresponding connector 7, thereby improving the testing efficiency of different instrument modules.

[0049] like Figure 8 , Figure 9 and Figure 10As shown, in some embodiments of this utility model, the first control box 401 includes: a third box body 4011, a first back plate 4012 is provided on one side of the third box body 4011, and a plurality of first expansion plates 4014 are provided on the other side of the third box body 4011. The first expansion plates 4014 are used to connect to the corresponding plug-in interface 7. Optionally, eight first expansion plates 4014 are provided, and the two ends of each first expansion plate 4014 are connected to the third box body 4011 through two first disassembly devices 4013. Specifically, the first expansion plate 4014 is fixed to the third housing 4011 with bolts. The lower end of the third housing 4011 has a slot, into which the lower end of the first expansion plate 4014 is inserted. The first disassembly tool 4013 is connected to the first expansion plate 4014 via a first roller. When the first expansion plate 4014 needs to be disassembled, the bolts are first removed, and then the lower end of the first disassembly tool 4013 is moved upwards. The upper end of the first disassembly tool 4013 presses against the edge of the third housing 4011, allowing the first expansion plate 4014 to be pulled out of the slot, thus completing the disassembly of the first expansion plate 4014. Similarly, as... Figure 11 and Figure 12 As shown, the second control box 402 includes: a fourth box body 4021, a second back plate 4022 is provided on one side of the fourth box body 4021, and a plurality of second expansion plates 4024 are provided on the other side of the fourth box body 4021. The second expansion plates 4024 are used to connect to the corresponding plug-in interface 7. Optionally, eight second expansion plates 4024 are provided, and the two ends of each second expansion plate 4024 are connected to the fourth box body 4021 through two second disassembly devices 4023. Specifically, the second expansion plate 4024 is fixed to the fourth housing 4021 by bolts. The lower end of the fourth housing 4021 is provided with a slot. The lower end of the second expansion plate 4024 is inserted into the slot. The second disassembly device 4023 is connected to the second expansion plate 4024 through the second roller. When it is necessary to disassemble the second expansion plate 4024, the bolts are removed first. Then, the lower end of the second disassembly device 4023 is moved upward. The upper end of the second disassembly device 4023 presses against the edge of the fourth housing 4021, and the second expansion plate 4024 can be pulled out from the slot, thus completing the disassembly of the second expansion plate 4024. Based on the provision of various types of pre-installed interfaces 7 to meet the electrical testing requirements of different instrument modules, the types of compatible testing modules can be further expanded by replacing the first expansion board 4014 of the first control box 401 or changing the second expansion board 4024 of the second control box 402. This allows for compatibility with multiple instrument modules and meets the electrical testing requirements of different instrument modules without the need for additional electrical testing fixtures, effectively improving the versatility of the overall integrated electrical testing fixture.

[0050] In addition, a third fan 4025 is installed at the bottom of the fourth enclosure 4021, and a third heat dissipation hole is installed on the top surface of the fourth enclosure 4021. The third fan 4025 draws out the hot air inside the fourth enclosure 4021, and the cooler air outside the third enclosure 4011 enters the fourth enclosure 4021 through the fourth heat dissipation hole, so that an air circulation effect is formed inside the fourth enclosure 4021, which effectively reduces the temperature inside the fourth enclosure 4021 and provides a certain degree of protection for the electronic components inside the third enclosure 4011.

[0051] In summary, by connecting the module to be tested to the control component 4 through the corresponding interface 7, the electrical testing requirements of different instrument modules can be met. The qualification of the module can be determined before the instrument module is assembled, eliminating the need for repeated disassembly and inspection. This proactive approach to problem detection effectively improves the overall assembly efficiency.

[0053] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
