Abstract
Description
Technical Field
[0001] This utility model relates to the field of fiber optic amplifier technology, specifically a high-precision Chinese dynamic digital display amplifier. Background Technology
[0002] A digital display fiber optic amplifier is a photoelectric detection device that combines fiber optic sensing technology with digital display functionality. It is mainly used in fields such as industrial automation, logistics sorting, and packaging inspection. It amplifies fiber optic signals with high precision and displays the detection results intuitively in digital form.
[0003] Mechanical vibrations in industrial environments (such as equipment operation and material handling), bumps during transportation, and periodic impacts from electromagnetic drive components (such as motors and cylinders) can all be transmitted to the amplifier's interior through the mounting bracket. Precision components inside the amplifier, such as optical lenses and fiber optic couplers, may experience slight displacements under vibration, leading to optical path shifts or reduced coupling efficiency, directly affecting signal amplification accuracy. Secondly, traditional amplifiers often use sealed housings for dust protection, but the heat generated by internal electronic components (such as lasers, photodetectors, and operational amplifiers) under high loads is difficult to dissipate quickly, resulting in localized temperature rises. Temperature changes can cause drift in parameters such as dark current and gain of photoelectric components, distorting the detection signal and reducing dynamic display accuracy. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a high-precision Chinese dynamic digital display amplifier, which has advantages such as good heat dissipation and vibration reduction, thus solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision Chinese dynamic digital display amplifier, including a main body shell and an L-shaped frame at the bottom. A cooling rectangular tube is fixedly connected to the inner bottom wall of the main body shell. The cooling rectangular tube has an inverted U-shaped structure, with both ends of the cooling rectangular tube located below the main body shell. A plurality of equidistant fins are fixedly embedded in the inner top wall of the cooling rectangular tube, with the top of each fin located above the rectangular cooling tube.
[0006] A shock-absorbing component is provided between the L-shaped frame and the main shell;
[0007] The L-shaped frame has a clamping groove on one side, and a cable fixing component is installed inside the clamping groove.
[0008] Furthermore, a miniature fan is installed at one end of the L-shaped frame, and the miniature fan is located below one end of the cooling rectangular tube.
[0009] Through the above scheme, the micro fan can actively deliver air into the cooling rectangular tube, accelerate airflow, improve heat dissipation efficiency, and enable the amplifier to maintain good heat dissipation performance even when working under high load for a long time.
[0010] Furthermore, the shock absorption assembly includes a shock absorption sleeve and a shock absorption block. The bottom end of the shock absorption sleeve is fixedly connected to the L-shaped frame, the top end of the shock absorption block is fixedly connected to the bottom of the main body shell, the shock absorption block and the shock absorption sleeve are slidably inserted into each other, and multiple shock absorption springs are provided between the shock absorption block and the shock absorption sleeve.
[0011] With the above solution, when external vibration occurs, the damping block slides inside the damping sleeve, and the damping spring undergoes elastic deformation, absorbing and buffering the vibration energy, thereby effectively reducing the impact of vibration on the amplifier.
[0012] Furthermore, a damping block is provided between the main body shell and the L-shaped frame.
[0013] Through the above scheme, the damping block can consume the excess energy generated during the damping process, prevent the damping block from swaying back and forth inside the damping sleeve, make the damping process more stable, and further reduce the interference of vibration on the internal components of the amplifier.
[0014] Furthermore, the cable fixing assembly includes two plug rods, both of which are slidably inserted into the top of the L-shaped frame. The ends of the two plug rods that are close to each other are fixedly connected to a fixing plate. The sides of the two fixing plates that are close to each other are provided with a set of arc-shaped grooves. A return spring is fixedly connected between the two fixing plates and the L-shaped frame.
[0015] With the above method, when it is necessary to fix the optical fiber, pull the plug outward to insert the optical fiber between the fixing plates, release the plug, and the elastic force of the return spring will bring the fixing plates closer together, and the arc groove will fit the surface of the optical fiber to achieve stable fixation of the optical fiber.
[0016] Furthermore, the cooling rectangular tube and multiple fins are integrally formed.
[0017] The above solution improves the heat transfer efficiency between the cooling rectangular tube and the fins, and enhances the heat dissipation effect through airflow.
[0018] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:
[0019] This high-precision Chinese dynamic digital display amplifier utilizes an inverted U-shaped cooling rectangular tube that extends to the exterior of the main casing. Combined with embedded fins, this forms an airflow channel, allowing heat dissipation within a closed path. This prevents external dust intrusion and significantly improves heat exchange efficiency by increasing the heat dissipation area, ensuring stable operation of internal electronic components. This reduces signal drift or component aging caused by overheating, extending equipment lifespan. The sliding insertion structure of the shock-absorbing block and sleeve, along with the shock-absorbing spring, initially absorbs vertical vibration energy. The damping block further dissipates residual vibration, preventing repeated oscillations. The insertion rod and fixing plate achieve adaptive clamping via a reset spring, and the arc-shaped groove adheres to the fiber optic surface for reliable fixation, effectively resisting external pulling or shaking. This prevents signal interruption caused by fiber optic loosening, ensuring reliable real-time detection in industrial automation processes and reducing production failures due to connection failures.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0032] Please see Figure 1 , Figure 4 and Figure 5 The high-precision Chinese dynamic digital display amplifier in this embodiment includes a main body shell 1 and an L-shaped frame 2 at the bottom. A cooling rectangular tube 3 is fixedly connected to the inner bottom wall of the main body shell 1. The cooling rectangular tube 3 has an inverted U-shaped structure, with both ends of the cooling rectangular tube 3 located below the main body shell 1. Multiple fins 4 are fixedly embedded in the inner top wall of the cooling rectangular tube 3, with the top of each fin 4 located above the rectangular cooling tube. Through the above arrangement, when airflow enters the cooling rectangular tube 3 through one end, it can achieve the purpose of cooling the surface of the cooling rectangular tube 3. Then, the airflow is discharged through the other end. While achieving the purpose of heat dissipation, it can also prevent external dust from entering the interior of the main body shell 1, ensuring that the internal electronic components of the amplifier operate stably at a suitable temperature and reducing the risk of performance degradation or damage due to overheating. The cooling rectangular tube 3 and the multiple fins 4 are integrally formed.
[0033] Please see Figure 1 , Figure 2 and Figure 3 A miniature fan 8 is installed at one end of the L-shaped frame 2. The miniature fan 8 is located below one end of the cooling rectangular tube 3. The miniature fan 8 can actively send air into the cooling rectangular tube 3 to accelerate airflow and improve heat dissipation efficiency, so that the amplifier can maintain good heat dissipation performance even when working under high load for a long time. A shock-absorbing component 5 is set between the L-shaped frame 2 and the main shell 1. The cable fixing component 7 can fix the outer surface of the optical fiber, effectively preventing the optical fiber from loosening or falling off due to external pulling, shaking and other factors, and ensuring the stability and reliability of signal transmission.
[0034] Please see Figure 1 , Figure 2 and Figure 3The vibration damping assembly 5 includes a vibration damping sleeve 501 and a vibration damping block 502. The bottom end of the vibration damping sleeve 501 is fixedly connected to the L-shaped frame 2, and the top end of the vibration damping block 502 is fixedly connected to the bottom of the main body shell 1. The vibration damping block 502 and the vibration damping sleeve 501 are slidably inserted into each other. Multiple vibration damping springs 503 are provided between the vibration damping block 502 and the vibration damping sleeve 501. When external vibration occurs, the vibration damping block 502 slides in the vibration damping sleeve 501, and the vibration damping springs 503 undergo elastic deformation to absorb and buffer vibration energy, thereby effectively reducing the impact of vibration on the amplifier. A damping block 504 is provided between the main body shell 1 and the L-shaped frame 2. The damping block 504 can consume the excess energy generated during the vibration damping process, prevent the vibration damping block 502 from swaying back and forth in the vibration damping sleeve 501, make the vibration damping process more stable, and further reduce the interference of vibration on the internal components of the amplifier.
[0035] Please see Figure 1 , Figure 2 and Figure 3 One side of the L-shaped frame 2 has a clamping groove 6, inside which a cable fixing component 7 is installed. The cable fixing component 7 secures the outer surface of the optical fiber, effectively preventing it from loosening or falling off due to external pulling or shaking, thus ensuring the stability and reliability of signal transmission. The cable fixing component 7 includes two insertion rods 701, both with beveled outer surfaces. Both insertion rods 701 are slidably inserted into the top of the L-shaped frame 2. Each of the two insertion rods 701 has a fixed plate 702 fixedly connected to one end of each other. Each of the two fixed plates 702 has a set of arc-shaped grooves 703 on one side of each other. Each of the two fixed plates 702 and the L-shaped frame 2 has a fixed return spring 704 fixedly connected to it. When it is necessary to fix the optical fiber, pull the insertion rod 701 outward to put the optical fiber between the fixed plates 702. Release the insertion rod 701, and the elastic force of the return spring 704 will make the fixed plates 702 move closer to each other. The arc-shaped grooves 703 fit against the surface of the optical fiber to achieve stable fixation of the optical fiber.
[0036] It should be noted that during installation, the L-shaped frame 2 must be rigidly connected to the equipment base to prevent external high-frequency vibrations from being transmitted to the amplifier through the base and weakening the buffering effect of the shock absorption component 5.
[0037] The working principle of the above embodiment is as follows: After the micro fan 8 is started, it actively sends air to one end of the cooling rectangular tube 3. The airflow flows along the inverted U-shaped channel and passes through multiple fins 4 on the inner top wall in sequence. The fins 4 and the cooling rectangular tube 3 are integrally formed to form a high thermal conductivity heat dissipation structure. By increasing the surface area, the heat exchange efficiency is enhanced. The airflow path is completely outside the main body shell 1, and the internal components are only indirectly cooled through the wall of the cooling rectangular tube 3, avoiding dust intrusion with the airflow. The heat generated by the internal electronic components, such as lasers and photodetectors, is conducted through the shell to the cooling rectangular tube 3 and then carried out by the airflow. When the amplifier is running under high load, the micro fan 8 continuously accelerates the airflow to compensate for the increased heat dissipation demand due to component heating. Under low load, natural convection and passive heat dissipation by the fins 4 can maintain a stable temperature, balancing energy efficiency and heat dissipation effect. When external vibrations are transmitted to the L-shaped frame 2, the shock absorber 502 slides vertically within the shock absorber sleeve 501, compressing the shock absorber spring 503 to absorb the impact energy. The spring deformation amplitude is proportional to the vibration intensity, achieving initial energy dissipation. The damping block 504 is located at the contact surface between the main body shell 1 and the L-shaped frame 2. Through friction or viscous damping characteristics, it converts the residual kinetic energy of the shock absorber 502 during sliding into heat energy, preventing the spring rebound from causing secondary oscillations. Next, the optical fiber is inserted along the clamping slot 6 of the L-shaped frame 2. The two insertion rods 701 are pulled outwards with both hands, and the fixing plate 702 separates under the traction of the return spring 704, forming a gap that can accommodate the optical fiber. After releasing the insertion rods 701, the return spring 704 drives the fixing plate 702 to slide inwards to fix the cable, preventing signal interruption due to shaking or pulling.
