Description

Technical Field

[0001] This utility model belongs to the field of optical fiber module technology, and in particular relates to a quick-release optical fiber module pre-assembly clamping fixture. Background Technology

[0002] The quick-release optical module fiber pre-assembly clamping fixture is a special fixture used to quickly fix and adjust optical fibers during the assembly or testing of optical modules. Its core design features are quick disassembly and repeated installation, while ensuring fiber positioning accuracy and ease of operation.

[0003] Chinese patent discloses an optical fiber clamping device, publication number CN222105695U. The paper proposes that "by rotating a knob, the knob rotation drives the threaded rod to rotate in the inner cavity of the bearing seat. The rotation of the threaded rod drives the threaded block to move on the surface of the threaded rod through the thread. The movement of the threaded block drives the lifting plate to press against the first pressing spring. The movement of the lifting plate drives the guide sleeve to move on the surface of the guide rod. At the same time, the movement of the guide sleeve drives the second pressing spring. The movement of the guide sleeve drives the guide block to slide in the inner cavity of the guide groove. The movement of the lifting plate drives the lifting column to move upward. The movement of the lifting column drives the clamping plate to leave the top of the placement table. Then, three optical fibers are placed in the inner cavity of the placement groove at the top of the placement table respectively."

[0004] However, in the above solution, the original knob needs to be rotated 5-10 times, which is time-consuming. It is not convenient enough in testing and maintenance scenarios where fiber optic cables need to be replaced frequently, and it cannot achieve the effect of quick disassembly. Utility Model Content

[0005] This utility model provides a quick-release optical module fiber pre-installation clamping fixture, which aims to solve the problem that some existing knobs require 5-10 rotations, which is time-consuming and inconvenient in testing and maintenance scenarios where frequent fiber replacement is required, and cannot achieve the effect of quick release.

[0006] This utility model is implemented as follows: a quick-release optical module fiber pre-assembly clamping fixture includes a mounting plate; an upper clamp mounted on one side of the mounting plate, with a lower clamp below the upper clamp, and a first clamping pad provided on the inner side of both the lower and upper clamps, which can clamp the optical fiber; an adjustment box distributed above the upper clamp, which is fixedly connected to the mounting plate, and the adjustment box can adjust the height of the upper clamp; a transmission box fixedly connected to the top of the adjustment box, with a side plate fixed to the side of the transmission box, and a slider slidably connected inside the side plate, the top of the slider being connected to a pull rope.

[0007] Preferably, a connecting rod is provided at the top of the upper clamp, and a plate-shaped lifting plate is fixed to the end of the connecting rod away from the upper clamp.

[0008] Preferably, the top center of the lifting plate is fixedly connected to the end of the pull rope away from the slider, and a rectangular groove is provided at the connection between the top center of the adjustment box and the pull rope.

[0009] Preferably, four sets of sliding rods are fixedly distributed inside the adjusting box. The sliding rods are slidably connected to the lifting plate, and a sliding hole is provided at the connection between the lifting plate and the sliding rod. A first spring is distributed on the outside of the sliding rod, and the length of the first spring is greater than the length of the sliding rod.

[0010] Preferably, the transmission box is internally equipped with two sets of first pulleys and second pulleys, with the first pulleys located above the rectangular groove and the second pulleys located on the top of the side plate. The first pulleys and second pulleys are in contact with the pull rope.

[0011] Preferably, a limiting groove is provided at the connection between the side plate and the slider, and a limiting plate is fixed at the top of the limiting groove, and a hole is provided in the middle of the limiting plate, and a pull rope passes through the inside of the hole.

[0012] Preferably, the slider includes: two sets of levers slidably connected to the side of the slider away from the adjustment box, and the two sets of levers are mirror-distributed; a plug is vertically fixed to the end of the lever near the adjustment box, and the plug is located on the side of the lever near the side plate; a first telescopic groove is provided at the connection between the slider and the plug and the lever; a telescopic rod is fixed inside the first telescopic groove, and the telescopic rod is slidably connected to the plug; a second telescopic groove is provided at the connection between the plug and the telescopic rod; a second spring is provided inside the second telescopic groove, and the length of the second spring is greater than the length of the second telescopic groove.

[0013] Preferably, a limiting slot is provided at the connection between the insertion rod and the side plate, and the limiting slot is located at the lower end of the limiting groove of the side plate.

[0014] Compared with related technologies, the quick-release optical module fiber pre-assembly clamping fixture provided by this utility model has the following advantages:

[0015] 1. When the slider moves downward, the pull rope can be turned on the first and second pulleys, pulling the lifting plate upward inside the adjustment box. This allows the upper clamp to move upward via the connecting rod at the bottom, thus separating the upper and lower clamps for quick separation of the optical fiber.

[0016] 2. By pinching the two sets of levers and moving them inward, the plug can be released from the inside of the limit slot. At this time, the first spring on the outside of the slide bar will extend and push the lifting plate downward, so that the upper and lower clamps can be closed, making it convenient to quickly clamp the placed optical fiber.

[0025] Example 1

[0026] A preferred embodiment of the quick-release optical module fiber pre-assembly clamping fixture provided by this utility model is, for example... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown: A quick-release optical module fiber pre-assembly clamping fixture includes a mounting plate 1; an upper clamp 2 mounted on one side of the mounting plate 1, a lower clamp 3 located below the upper clamp 2, and first clamping pads 201 located on the inner sides of both the lower clamp 3 and the upper clamp 2, which can clamp the optical fiber; an adjustment box 4 located above the upper clamp 2, which is fixedly connected to the mounting plate 1 and can adjust the height of the upper clamp 2; a transmission box 5 fixedly connected to the top of the adjustment box 4, a side plate 503 fixedly attached to the side of the transmission box 5, a slider 6 slidably connected inside the side plate 503, and a pull rope 7 connected to the top of the slider 6.

[0027] It should be noted that the original knob required 5-10 rotations, which was time-consuming and inconvenient for testing and maintenance scenarios where fiber optic cables needed to be frequently replaced, thus failing to achieve a quick-release effect.

[0028] In this embodiment, by sliding the slider 6 downwards, the slider 6 pulls the upper clamp 2 upwards via the pull rope 7, thereby enabling the lower clamp 3 and the upper clamp 2 to separate quickly, facilitating the quick release of the clamped optical fiber.

[0029] In a further preferred embodiment of the present invention, a connecting rod 202 is provided on the top of the upper clamp 2, and a plate-shaped lifting plate 203 is fixed to the end of the connecting rod 202 away from the upper clamp 2.

[0030] In this embodiment, the lifting plate 203 is distributed inside the adjusting box 4, so that the upper clamp 2 can be moved easily by the lifting plate 203. The lifting plate 203 can be pulled upward by the pull rope 7 and then pushed downward by the first spring 402 inside the box 4.

[0031] In a further preferred embodiment of the present invention, four sets of slide rods 401 are fixedly distributed inside the adjusting box 4. The slide rods 401 are slidably connected to the lifting plate 203, and a sliding hole 204 is provided at the connection between the lifting plate 203 and the slide rods 401. A first spring 402 is distributed on the outer side of the slide rods 401, and the length of the first spring 402 is greater than the length of the slide rods 401.

[0032] In this embodiment, the first spring 402 provided on the outer side of the rod 401 extends and pushes the lifting plate 203 to move downward, thereby causing the upper clamp 2 to move downward and clamp the optical fiber with the lower clamp 3.

[0033] In a further preferred embodiment of the present invention, the top center of the lifting plate 203 is fixedly connected to the end of the pull rope 7 away from the slider 6, and a rectangular groove 403 is provided at the connection between the top center of the adjusting box 4 and the pull rope 7.

[0034] In this embodiment, this makes it easy to pull the rope 7 into the interior of the adjustment box 4, and then drive the lifting plate 203 to move.

[0035] In a further preferred embodiment of the present invention, the transmission box 5 is provided with two sets of first pulleys 501 and second pulleys 502, with the first pulleys 501 distributed above the rectangular groove 403 and the second pulleys 502 distributed on the top of the side plate 503. The first pulleys 501 and the second pulleys 502 are in contact with the pull rope 7.

[0036] In this embodiment, the first pulley 501 and the second pulley 502 can change the pulling direction of the pull rope 7, so that the downward sliding direction of the slider 6 can drive the lifting plate 203 to move upward.

[0037] In a further preferred embodiment of the present invention, a limiting groove 505 is provided at the connection between the side plate 503 and the slider 6, and a limiting plate 504 is fixed at the top of the limiting groove 505. A hole is provided in the middle of the limiting plate 504, and a pull rope 7 passes through the hole of the limiting plate 504.

[0038] In this embodiment, the limiting plate 504 can limit the upward movement distance of the slider 6, and the slots are also convenient for the pull rope 7 to pass through, so as to realize the transmission of the slider 6 to the lifting plate 203.

[0039] In a further preferred embodiment of this utility model, the slider 6 includes: two sets of levers 601 slidably connected to the side of the slider 6 away from the adjustment box 4, and the two sets of levers 601 are mirror-distributed. A plug rod 602 is vertically fixed to the end of the lever 601 near the adjustment box 4, and the plug rod 602 is located on the side of the lever 601 near the side plate 503. A first telescopic groove 603 is provided at the connection between the slider 6 and the plug rod 602 and the lever 601; a telescopic rod 604 is fixed inside the first telescopic groove 603, and the telescopic rod 604 is slidably connected to the plug rod 602. A second telescopic groove 605 is provided at the connection between the plug rod 602 and the telescopic rod 604. A second spring 606 is provided inside the second telescopic groove 605, and the length of the second spring 606 is greater than the length of the second telescopic groove 605.

[0040] In this embodiment, after the slider 6 slides downward, the second spring 606 inside the second telescopic groove 605 can extend to push the insertion rod 602 outward. When the insertion rod 602 is inserted into the limiting slot 506, the position of the slider 6 after sliding downward can be fixed, which makes it convenient to place and pick up the optical fiber. When it needs to be reset, just pinch the two sets of levers 601 and move them inward to release the insertion rod 602 from the inside of the limiting slot 506 to release the fixation.

[0041] In a further preferred embodiment of the present invention, a limiting slot 506 is provided at the connection between the insertion rod 602 and the side plate 503, and the limiting slot 506 is located at the lower end of the limiting groove 505 of the side plate 503.

[0042] In this embodiment, the limiting slot 506 can fix the position of the slider 6 when the insertion rod 602 is inserted, thus fixing the position of the upward-moving upper clamp 2.

[0043] In summary, by setting up the transmission box 5 and the slider 6, when the slider 6 moves downward, the pull rope 7 can turn on the first pulley 501 and the second pulley 502, pulling the lifting plate 203 upward inside the adjusting box 4. This allows the upper clamp 2 to move upward via the connecting rod 202 at the bottom, thus separating the upper clamp 2 from the lower clamp 3 for quick separation of the optical fiber. Meanwhile, when the downward-moving slider 6 reaches the lower end of the side plate 503, the second spring 606 inside the second telescopic groove 605 can... By extending the insertion rod 602 outward, when the insertion rod 602 is inserted into the limiting slot 506, the position of the sliding slider 6 after sliding downward can be fixed, which facilitates the placement and handling of optical fibers. By pinching the two sets of levers 601 and moving them inward, the insertion rod 602 can be disengaged from the inside of the limiting slot 506 to release the fixation. At this time, the first spring 402 on the outside of the slide rod 401 will extend, pushing the lifting plate 203 downward, so that the upper clamp 2 and the lower clamp 3 can be closed, which facilitates the quick clamping of the placed optical fibers.
