Description

Technical Field

[0001] This utility model belongs to the field of optical component technology, and in particular relates to an optical component coupling fixture for low-temperature environments. Background Technology

[0002] In low-temperature environments, the coupling operation of optical components faces many challenges, among which the clamping process is particularly critical. Traditional clamps suffer from changes in material properties at low temperatures. For example, metal clamps may experience changes in dimensional accuracy due to cold contraction, making it difficult to stably clamp optical components and easily causing stress concentration, which can damage fragile optical components. Ordinary plastic clamps become brittle at low temperatures, losing their elasticity and toughness, significantly reducing clamping reliability. At the same time, the thermal expansion and contraction characteristics of optical components at low temperatures are different from those at room temperature, requiring clamps to have more precise adaptive adjustment capabilities to ensure that they can still stably and accurately clamp optical components under complex working conditions, meeting the high-precision requirements of optical component coupling.

[0003] However, existing optical component coupling fixtures for low-temperature environments are not convenient for fixing the optical components that need to be coupled during use. This causes the optical components to easily shift or shake during the coupling process, which affects the accuracy and precision of the coupling and reduces the quality and stability of optical signal transmission. Utility Model Content

[0004] The purpose of this utility model is to provide a coupling fixture for optical components in low-temperature environments. By setting a fixing mechanism, it solves the problem that existing coupling fixtures for optical components in low-temperature environments are not convenient for fixing the optical components to be coupled during use, which leads to the optical components being prone to displacement or shaking during coupling, thereby affecting the accuracy and precision of coupling and reducing the quality and stability of optical signal transmission.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a coupling fixture for optical components in low-temperature environments, including a base, on which a fixing mechanism and an adjustment mechanism are provided;

[0007] The fixing mechanism includes a slider slidably connected to the top of the base, a hinge block fixedly connected to the top of the slider, a connecting block hinged to the hinge block, a connecting rod fixedly connected to the top of the connecting block, and a locking block fixedly connected to the right side of the connecting block. The adjusting mechanism includes a platform fixedly connected to the top of the slider, a laser mounted on the platform, and the locking block being adapted to the laser.

[0008] Furthermore, a slider two is slidably connected to the outer wall of the connecting rod one, a connecting block two is hinged on the slider two, and a connecting rod two is hinged on the slider two.

[0009] Furthermore, a second latching block is hinged to the top of the second connecting rod, which is adapted to the platform. A third connecting block is fixedly connected to the top of the first connecting rod, and the top of the third connecting block is hinged to the second latching block. A first spring is sleeved on the outer wall of the first connecting rod, and the top of the first spring is fixedly connected to the third connecting block. The bottom of the first spring is fixedly connected to the second slider.

[0010] Furthermore, a hinge block two is fixedly connected to the top of the slider one, a connecting block four is hinged to the hinge block two, an electric telescopic rod is fixedly connected to the top of the connecting block four, and the output shaft of the electric telescopic rod is fixedly connected to the connecting block two.

[0011] Furthermore, two sliders are slidably connected to the platform, and two grooves are formed on the platform. The bottoms of the two sliders are slidably connected to the two grooves respectively. Limiting rods are fixedly connected to the inner walls of the two grooves respectively, and the two limiting rods pass through the two sliders.

[0012] Furthermore, spring 2 is sleeved on the outer wall of each of the two limiting rods. The side of the two spring 2 that is close to each other is fixedly connected to two sliders 3 respectively, and the side of the two spring 2 that is far from each other is fixedly connected to two sliding grooves respectively. Connecting block 5 is fixedly connected to the front and rear sides of the base. Limiting block is fixedly connected to the top of the base. The outer wall of the limiting block is slidably connected to slider 1.

[0013] Furthermore, a threaded rod is rotatably connected between the two connecting blocks five. The outer wall of the threaded rod is threadedly connected to the slider. A worm gear is fixedly connected to the outer wall of the threaded rod. A worm is rotatably connected to the inner wall of the front connecting block five. The worm meshes with the worm gear. A motor is fixedly connected to the inner wall of the front connecting block five. The output shaft of the motor is fixedly connected to the worm through a coupling.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting a fixing mechanism, during installation, the electric telescopic rod can be activated to move its output shaft. When the output shaft of the electric telescopic rod moves, it will drive the slider two to slide upward through the connecting block two, thereby applying pressure to the spring one, causing it to undergo elastic deformation and generate elastic force. At the same time, when the output shaft of the electric telescopic rod moves, it will drive the connecting block one to rotate on the hinge block one through the connecting rod one, thereby causing the locking block one to apply pressure to the laser and squeeze it. When the slider two slides, under the action of the connecting block three, the connecting rod two drives the locking block two to squeeze the laser, thereby fixing the laser on the platform. This allows it to be fixed when coupling the optical components, preventing it from easily shifting or shaking during the coupling process, avoiding affecting the accuracy and precision of the coupling, and thus ensuring the quality and stability of the optical signal transmission.

[0016] 2. By setting up an adjustment mechanism, during use, pull out the two sliders three, allowing them to slide within the two grooves respectively. This applies pressure to the two springs two, causing them to elastically deform and generate elastic force. Then, place the laser between the two sliders three at the top of the platform, and activate the fixing mechanism to secure the laser. After installation, start the motor to rotate its output shaft. The rotation of the motor's output shaft will drive the threaded rod to rotate under the interaction of the worm and worm wheel. This, in turn, will cause the slider one to slide on the top of the base under the action of the limit block, allowing for adjustment. The centering of the laser ensures accurate adjustment, enabling further adjustments after the optical components are fixed. This not only makes operation simple and convenient but also improves coupling accuracy and enhances system stability, thereby further ensuring the quality and stability of optical signal transmission.

Limiting rods 304 are fixedly connected to the inner walls of both grooves 303. The two limiting rods 304 pass through the two sliders 302 respectively. Springs 305 are fitted onto the outer walls of both limiting rods 304.

This not only makes the operation simple and convenient, but also improves the coupling accuracy and enhances the system stability, thereby further ensuring the quality and stability of optical signal transmission.

[0030] One specific application of this embodiment is as follows: In use, the two sliders 302 are pulled apart, allowing them to slide within the two grooves 303 respectively, thereby applying pressure to the two springs 305, causing them to undergo elastic deformation and generate elastic force. Then, the laser 101 is placed between the two sliders 302 at the top of the platform 301. The laser 101 is a kg-pt type 40 GHz high-speed optical detection module, which operates based on the photoelectric effect. It integrates a high-speed PIN detector and a TIA amplifier chip. The optical signal input from the single-mode fiber is detected by the PIN detector. The signal is converted into a weak electrical signal, amplified by the TIA amplifier chip, and finally output as a high-gain, high-sensitivity AC-coupled electrical signal. Then, the two sliders 302 are released, pushing the laser 101 to the center. The electric telescopic rod 214 can then be activated, causing its output shaft to move. As the output shaft of the electric telescopic rod 214 moves, it drives the slider 206 upwards via the connecting block 207, thus applying pressure to the spring 211, causing it to elastically deform and generate elastic force. Simultaneously, as the output shaft of the electric telescopic rod 214 moves, it also drives the slider 206 upwards via the connecting rod 207. 204 drives connecting block 203 to rotate on hinge block 202, thereby causing clamping block 205 to apply pressure to laser 101, squeezing it. When slider 206 slides, under the action of connecting block 310, connecting rod 208 drives clamping block 209 to squeeze laser 101, thereby fixing laser 101 on platform 301. After installation, motor 311 can be started to rotate its output shaft. The rotation of motor 311's output shaft will drive threaded rod 30 under the interaction of worm 310 and worm wheel 309. The device rotates, thereby driving the slider 201 to slide on the top of the base 1 under the action of the limit block 307, so that it can be adjusted. The centering of the laser 101 can ensure the accuracy of the adjustment. The main material of the device is zirconia ceramic, which has high strength, high hardness, good wear resistance and chemical stability. In low temperature environment, its coefficient of thermal expansion is similar to that of some optical component materials, which can reduce the stress caused by the difference of thermal expansion and contraction, thereby better protecting the optical component. At the same time, the insulation performance of zirconia ceramic can also avoid electrical interference to the optical component.
