Abstract
Description
Technical Field
[0001] This utility model relates to the field of monitoring device technology, specifically a laser emission module frequency jitter monitoring device. Background Technology
[0002] The laser emission module frequency jitter monitoring device is a specialized testing equipment used to collect and analyze the frequency fluctuation parameters (including jitter amplitude, drift period, and fluctuation peak value) of the laser output from the laser emission module in real time. Through its built-in photoelectric conversion unit, signal filtering unit, and data processing unit, it converts the laser signal into an electrical signal and performs quantitative analysis. Finally, it outputs the test results to determine whether the frequency jitter meets the preset standards, thereby ensuring the stability and accuracy of the laser module in communication, laser processing, and ranging sensing scenarios.
[0003] However, existing jitter monitoring devices rely on manual alignment and bolt tightening during use, resulting in low installation efficiency and potential alignment deviations due to human error, thus affecting the accuracy of frequency jitter data. Therefore, those skilled in the art have provided a laser emission module frequency jitter monitoring device to address the problems mentioned in the background section. Utility Model Content
[0004] The purpose of this invention is to provide a laser emission module frequency jitter monitoring device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A laser emission module frequency jitter monitoring device includes a mounting plate, a metal base fixed to the bottom of the mounting plate, an assembly mechanism provided on the outer side of the mounting plate, a mounting seat provided on the top of the mounting plate, a jitter detection device body fixed to the top of the mounting seat by bolts, and a positioning and reinforcement mechanism provided on the outer side of the mounting seat. The assembly mechanism includes an electric push rod. One end of the output shaft of the electric push rod is rotatably connected to a first rotating frame via a rotating shaft. A rotating connecting shaft is provided on the outer side of the first rotating frame. A second rotating frame is rotatably connected to the bottom of the mounting plate via a rotating shaft. A guide rail is fixed on the top of the mounting plate. Two movable limiting frames are slidably connected to the outer side of the guide rail. A connecting rod is fixed at the bottom of the movable limiting frame. Both the first and second rotating frames have movable limiting grooves inside. The size of the movable limiting groove is adapted to the size of the connecting rod. A positioning rod is fixed on one side of the movable limiting frame.
[0006] As an improvement of this utility model: a limiting groove is provided inside the movable limiting frame, and the limiting groove fits against the outer wall of the mounting base.
[0007] As an improvement of this utility model: both sides of the mounting base are provided with grooves, the size of which is adapted to the size of the positioning rod, and one side of the electric push rod is rotatably connected to the mounting plate through a rotating shaft.
[0008] As an improvement of this utility model: the positioning and reinforcement mechanism includes a fixing strip, the fixing strip has a plurality of connecting grooves inside, the main body of the vibration detection device has a plurality of positioning threaded rods fixed outside, the positioning threaded rods are threaded with positioning nuts on the outer side, and the fixing strip has an installation groove inside.
[0009] As an improvement of this utility model: the fixing strip and the mounting base are fixedly connected, and one side of the fixing strip is attached to the outer wall of the main body of the vibration detection device.
[0010] As an improvement of this utility model: the mounting base and the main body of the vibration detection device are both provided with several threaded holes that are adapted to different positions, and the size of the connecting groove is adapted to the size of the positioning threaded rod.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. By incorporating an assembly mechanism, two movable limit frames move synchronously in opposite directions, allowing one end of the positioning rod to be inserted into a pre-set groove on the mounting base. This enables rapid and precise alignment, clamping, and locking of the mounting base without the need for additional auxiliary tools. This simplifies the installation and fixing process of the vibration detection device and avoids positional deviations that may occur during manual installation. It ensures that the monitoring device is in the preset detection posture, effectively reducing the risk of frequency monitoring data distortion due to installation deviations and thus improving the installation efficiency of the device.
[0012] 2. With the positioning and reinforcement mechanism, the assembly and fixation between the fixing strip and the main body of the vibration detection device can be easily completed. The threaded holes between the main body of the vibration detection device and the mounting base can be quickly aligned, shortening the disassembly and assembly time. At the same time, the fixing strip plays an auxiliary reinforcement role, ensuring the stable assembly between the mounting base and the main body of the vibration detection device.

[0015] The technical solution of this utility model will be further described in detail below with reference to specific embodiments:
[0016] First Embodiment
[0017] Please see Figures 1-5 A laser emission module frequency jitter monitoring device includes a mounting plate 1, a metal base 2 fixed to the bottom of the mounting plate 1, an assembly mechanism 3 provided on the outside of the mounting plate 1, a mounting base 4 provided on the top of the mounting plate 1, a jitter detection device body 5 fixed to the top of the mounting base 4 by bolts, and a positioning and reinforcement mechanism 6 provided on the outside of the mounting base 4. The assembly mechanism 3 includes an electric push rod 31. One end of the output shaft of the electric push rod 31 is rotatably connected to a first rotating frame 32 via a rotating shaft. A rotating connecting shaft 33 is provided on the outer side of the first rotating frame 32. A second rotating frame 34 is rotatably connected to the bottom of the mounting plate 1 via a rotating shaft. A guide rail 37 is fixed on the top of the mounting plate 1. Two movable limiting frames 36 are slidably connected to the outer side of the guide rail 37. A connecting rod 35 is fixed on the bottom of the movable limiting frame 36. Movable limiting grooves are provided inside the first rotating frame 32 and the second rotating frame 34. The size of the movable limiting grooves is adapted to the size of the connecting rod 35. A positioning rod 38 is fixed on one side of the movable limiting frame 36. A limiting groove is provided inside the movable limiting frame 36. The limiting groove fits against the outer wall of the mounting base 4. Grooves are provided on both sides of the mounting base 4. The size of the grooves is adapted to the size of the positioning rod 38. One side of the electric push rod 31 is rotatably connected to the mounting plate 1 via a rotating shaft.
[0018] With the above settings, when assembling the main body 5 of the vibration detection device, the mounting base 4 at the bottom of the main body 5 of the vibration detection device is placed on the mounting plate 1, and then the electric push rod 31 is started. The output shaft of the electric push rod 31 drives one end of the first rotating frame 32 to rotate. The first rotating frame 32 and the second rotating frame 34 are both rotatably connected to the electric push rod 31 through the rotating shaft. When the first rotating frame 32 rotates, it moves in the limiting groove of the second rotating frame 34 through the rotating connecting shaft 33, and drives the second rotating frame 34 to rotate. The first rotating frame 32 and the second rotating frame 34 synchronously drive the connecting rod 35 to move. The connecting rod 35 drives the movable limiting frame 36 to slide on the outside of the guide rail 37, so that the two movable limiting frames 36 move synchronously in opposite directions, and one end of the positioning rod 38 is inserted into the preset groove of the mounting base 4.
[0019] In summary, by incorporating the assembly mechanism 3, the two movable limit frames 36 move synchronously in opposite directions, and one end of the positioning rod 38 is inserted into the pre-set groove of the mounting base 4. This allows for rapid and precise alignment, clamping, and locking of the mounting base 4 without the need for additional auxiliary tools. This simplifies the installation and fixing process of the main body 5 of the vibration detection device and avoids positional deviations that may occur during manual installation. It ensures that the monitoring device is in the preset detection posture, effectively reducing the risk of frequency monitoring data distortion caused by installation deviations, and thus improving the installation efficiency of the device.
[0020] Second Embodiment
[0021] Please see Figures 1-5 Based on the first embodiment, the positioning and reinforcement mechanism 6 includes a fixing strip 61, the fixing strip 61 has a plurality of connecting grooves 62 inside, the vibration detection device body 5 has a plurality of positioning threaded rods 63 fixed outside, the positioning threaded rods 63 have a positioning nut 64 threadedly connected to the outside, the fixing strip 61 has an installation groove 65 inside, the fixing strip 61 and the mounting base 4 are fixedly connected, one side of the fixing strip 61 is in contact with the outer wall of the vibration detection device body 5, the mounting base 4 and the vibration detection device body 5 both have a plurality of threaded holes with matching positions inside, and the size of the connecting groove 62 is adapted to the size of the positioning threaded rod 63.
[0022] With the above settings, when the main body 5 of the vibration detection device is fixed on the top of the mounting base 4, the threaded holes between the mounting base 4 and the main body 5 of the vibration detection device need to be aligned first. Then, the fixing strip 61 is movably sleeved on the outside of the positioning threaded rod 63. At this time, the corresponding surface of the main body 5 of the vibration detection device fits into the mounting groove 65. Then, the positioning nut 64 is threadedly connected to the positioning threaded rod 63.
[0023] In summary, by providing the positioning and reinforcement mechanism 6, the assembly and fixation between the fixing strip 61 and the main body 5 of the vibration detection device can be easily completed, and the threaded holes between the main body 5 of the vibration detection device and the mounting base 4 can be quickly aligned, shortening the disassembly and assembly time. At the same time, the fixing strip 61 plays an auxiliary reinforcement role, ensuring the stable assembly between the mounting base 4 and the main body 5 of the vibration detection device.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
