Description

Technical Field

[0001] This utility model relates to the field of optical module technology, and more specifically, to an optical module that is easy to fix. Background Technology

[0002] During the production, assembly, repair, and replacement of optical modules, frequent installation and disassembly of the modules are required to meet different testing and debugging needs. Existing optical modules generally use bolt and nut fixing methods. During operation, wrenches or screwdrivers must be used to tighten the fixing bolts one by one. Each installation requires repeated alignment and tightening to ensure the module position is accurate. The operation is cumbersome and time-consuming, and the module shell or mounting base is easily damaged due to improper use of tools. Especially in the case of frequent module replacement on automated production lines, workers have to stop their work each time to use special tools for disassembly and assembly, which seriously affects the production cycle. The lack of a quick assembly / disassembly mechanism in traditional fixing methods has become a bottleneck restricting the assembly efficiency of optical modules. At the same time, threaded connections are prone to wear during repeated assembly and disassembly, leading to a decrease in fixing reliability, which cannot meet the urgent needs of optical modules for quick fixing and precise positioning during high-frequency assembly. Utility Model Content

[0003] (a) Technical problems to be solved In view of the problems existing in the prior art, the present invention provides an optical module that is easy to fix, so as to solve the technical problems mentioned in the background art.

[0004] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: an optical module that is easy to fix, including a mounting base and an optical module body. A rod is fixedly provided on the top surface of the mounting base, and multiple sets of rods are provided. A fixing plate is fixedly provided on the outer side of the optical module body, and multiple sets of fixing plates are provided with insertion holes. The insertion holes are respectively inserted into multiple sets of rods. A fixing mechanism is provided at the top of each set of rods. The fixing mechanism includes a fixing sleeve and a locking block. The fixing sleeve abuts against the top surface of the fixing plate and is inserted into the rod. An installation groove is provided on the outer wall of the fixing sleeve, and multiple sets of installation grooves are provided, each with a rotating shaft fixedly provided on its inner side. A torsion spring is fixedly connected to the outer wall of each set of rotating shafts. Multiple sets of locking blocks are provided and rotatably connected to the outer walls of the multiple sets of rotating shafts. The inner sides of the multiple sets of locking blocks are fixedly connected to the multiple sets of torsion springs. A locking groove is provided on the outer wall of the rod, and multiple sets of locking grooves are provided and respectively engage with multiple sets of locking blocks. A limiting sleeve is slidably provided on the outer wall of the fixing sleeve.

[0005] The present invention is further configured such that the tops of the multiple sets of card blocks are all arc-shaped and are slidably connected to the top surfaces of the multiple sets of mounting slots.

[0006] The present invention is further configured such that pulleys are rotatably provided on the outer side of each of the multiple sets of card blocks, and multiple sets of pulleys are provided.

[0007] The present invention is further configured such that a guide block is fixedly provided on the inner side of the limiting sleeve, and a guide groove is provided on the outer wall of the fixed sleeve. Multiple sets of the guide block and the guide groove are provided and slidably connected.

[0008] The present invention is further configured such that a support plate is fixedly provided on the bottom surface of the limiting sleeve, the support plate is provided in multiple sets and the inner side of each support plate is fixedly provided with a limiting plate, the limiting plate is provided in multiple sets, and a rotating plate is provided on the outer wall of the fixed sleeve.

[0009] The present invention is further configured such that a tension spring is connected to the bottom surface of the limiting sleeve, and a thrust bearing is connected between the bottom end of the tension spring and the rotating plate.

[0010] The present invention is further configured such that a positioning strip is fixedly provided on the inner side of the fixing sleeve, and a positioning groove is provided on the outer wall of the insertion rod, and multiple sets of the positioning strip and the positioning groove are provided and slidably connected.

[0011] The present invention is further configured such that an unlocking groove is provided on the outer wall of the rotating plate, and multiple sets of the unlocking groove are provided.

[0012] Compared with the prior art, this utility model provides an optical module that is easy to fix, and has the following beneficial effects: 1. This device achieves rapid loading and unloading of optical modules through a torsion spring driven self-locking mechanism. During operation, simply push the limit sleeve to drive the pulley to rotate and lock the block in the slot. Assembly can be completed without tools. When unlocking, the torsion spring automatically resets and drives the block to disengage from the slot. The rotation of the pulley reduces the pushing friction resistance, making the operation more effortless and smooth. It effectively solves the problems of cumbersome and time-consuming traditional bolt fixing and inconvenient tool operation.

[0013] 2. The elastic self-locking system of this device forms a fixing mechanism with automatic compensation function through the cooperation of torsion spring and locking block. After the locking block is engaged, the torsion spring continuously applies elastic restoring force to keep the locking block tightly pressed in the slot. When the optical equipment vibrates or the temperature changes cause thermal expansion and contraction, the torsion spring automatically adjusts the tension to compensate for the displacement change and prevents the fixing from loosening. This ensures that the optical module is always firmly fixed and does not shift, effectively solving the problem of optical axis offset and decreased imaging accuracy caused by loose fixing during long-term use.

[0014] 3. The dual-guide positioning system of this device provides reliable axial constraint through the precise cooperation between the guide block and the guide groove, and the positioning strip and the positioning groove, ensuring that the limit sleeve maintains the vertical movement trajectory without deviation. The thrust bearing realizes the smooth transmission of the tension spring force and reduces the rotational friction resistance, allowing the operator to free up both hands to debug the module. This state holding and automatic reset mechanism improves the convenience and safety of single-person operation. Attached Figure Description
