TECHNICAL FIELD
[0001] The utility model relates to optical detection technical field especially relates to a portable SPR tester. BACKGROUND
[0002] The portable SPR (surface plasmon resonance) tester is a kind of high-sensitivity optical detection equipment, can monitor the interaction between molecules in real time, such as protein-protein, antibody-antigen, drug-target etc.This technology is widely used in life science research, drug screening, environmental monitoring and food safety fields because of its label-free, real-time detection characteristics, and is an important tool for modern scientific research and industrial detection.Compared with traditional laboratory-type SPR equipment, portable SPR tester is more lightweight and flexible, can adapt to the needs of on-site detection or rapid analysis, significantly improves the convenience and efficiency of detection.
[0003] However, the portable SPR tester faces important challenges in heat dissipation and equipment stability during actual operation, especially in high-temperature environments. During the operation of electronic equipment and precision instruments, heat dissipation is a key link to ensure the stability of equipment performance and prolong the service life. Especially when running in high-temperature or high-load environments, the electronic components and optical modules inside the equipment will overheat due to heat accumulation, which not only affects the operating efficiency of the equipment, but also may cause damage to critical components, thereby affecting the accuracy of detection and the service life of the equipment.
[0004] Currently, the traditional heat dissipation method mainly relies on the combination of heat sinks and cooling fans, which absorbs heat through heat sinks and carries away heat with the help of air flow of the fan. However, this traditional heat dissipation method also has obvious limitations in long-term use. The surface of the heat sink is easy to adsorb dust and impurities in the air during operation, and with the passage of time, these accumulated dust will hinder the heat conduction efficiency of the heat sink, resulting in a decrease in heat dissipation performance. In addition, the dust accumulation on the heat sink will further affect the air flow circulation efficiency of the cooling fan, causing the internal temperature of the equipment to continue to rise. This situation not only reduces the operating efficiency of the equipment, but also accelerates the aging of electronic components and increases the maintenance cost of the equipment.
[0005] Therefore, a portable SPR tester is proposed to solve the above problems. UTILITY MODEL CONTENTS

[0034] With reference to Figure 1 - Figure 3The fixing mechanism comprises at least two hollow columns 3 fixedly connected outside the tester main body 6 through connecting columns 5, a spring 8 arranged inside the hollow column 3, a piston 7 slidingly connected inside the hollow column 3, a push rod 2 fixedly connected to the top of the piston 7, a suction cup 4 fixedly connected to the bottom of the hollow column 3, one end of the spring 8 fixedly connected to the bottom of the piston 7, the other end of the spring 8 abutting against the inner bottom wall of the hollow column 3, and the push rod 2 slidingly connected inside the hollow column 3 and fixedly connected with a disc at the end away from the piston 7. The tester main body 6 is provided with a control module for controlling the running states of the motor 19, the cooling fan 9 and the dust removal mechanism, and connected with external devices to realize real-time monitoring and data processing. The hollow column 3 serves as the main structure of the fixing device for accommodating the spring 8 and the piston 7 and is fixedly connected outside the tester main body 6 through the connecting column 5 to ensure the stability and firmness of the fixing mechanism. The connecting column 5 is used to stably connect the hollow column 3 with the tester main body 6 to provide a support structure for the fixing mechanism. The spring 8 arranged inside the hollow column 3 is used to provide a reset elastic force. When the push rod 2 is pressed down by an external force, the spring 8 will be compressed.

The piston 7 slidingly connected inside the hollow column 3 slides up and down under the drive of the push rod 2 to control the exhaust and backflow of air inside the hollow column 3, thereby forming a negative pressure effect. The push rod 2 fixedly connected to the top of the piston 7 serves as an external operating component for transmitting the external force to the piston 7 to realize the up-and-down movement of the piston 7. The push rod 2 slidingly connected inside the hollow column 3 ensures smooth movement of the push rod 2 in the hollow column 3. The disc fixedly connected to the end away from the piston 7 is the operating end, which is convenient for users to exert pressure to control the movement of the piston 7. The suction cup 4 fixedly connected to the bottom of the hollow column 3 is firmly adsorbed on the working surface through the negative pressure principle to ensure the stability and fixing effect of the tester main body 6 during the running process. One end of the spring 8 is fixedly connected to the bottom of the piston 7, and the other end abuts against the inner bottom wall of the hollow column 3 to form a stable reset elastic support structure, ensuring that the piston 7 can be reliably returned to the original position to maintain the adsorption effect of the suction cup 4. The tester main body 6 is provided with a control module serving as the core control unit of the tester for coordinating the running state of the device, controlling the motor 19, the cooling fan 9 and the dust removal mechanism. The control module is also connected with external devices for real-time monitoring of the device state, collection of running data and provision of data processing and analysis functions to ensure intelligent operation and efficient management of the device.
[0035] Working principle: in use, first of all, the tester body 6 is placed in the designated position, through the lower disc on the push rod 2, the piston 7 slides in the hollow column 3, the spring 8 is compressed, and the air in the hollow column 3 is discharged. After the disc is released, the reset action of the spring 8 pushes the piston 7 back to the initial position, at this time, the hollow column 3 forms a negative pressure, the suction cup 4 is firmly adsorbed on the working surface, ensuring the stability of the tester body 6, preventing displacement during operation.
[0036] When the tester works for a long time and generates heat, the fin 1 works with the cooling fan 9, and the heat on the fin 1 is taken away by the rapid airflow of the fan, ensuring the temperature stability of the tester body 6. In order to prevent the dust on the surface of the fin 1 from affecting the heat dissipation efficiency, start the motor 19 in the dust removal mechanism. The motor 19 drives the rotating disc 10 to rotate through its output end, and the eccentric shaft 11 on the top of the rotating disc 10 converts the rotary motion into linear motion, driving the rotating shaft 13, the sliding block 17 and the connecting shaft 14 to reciprocate on the sliding rail 16. The rubber plate 15 is connected with the sliding block 17 through the connecting shaft 14, and periodically hits the fin 1 with the movement of the sliding block 17, and uses vibration to clean the dust on the surface of the fin 1.
[0037] The control module manages the operation of the whole device in real time, including controlling the start and stop of the motor 19, the cooling fan 9 and the dust removal mechanism, and connecting with external devices to realize the monitoring of the running state and data processing. The whole system closely cooperates in stability, heat dissipation efficiency and dust removal function, ensures the stability and portability of the tester in efficient operation, and adapts to the needs of different working environments.
[0038] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
