Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical fiber technology, and in particular to an optical fiber fixing mechanism and a fiber distribution box. Background Technology
[0002] Against the backdrop of rapid development in the communications industry, some basic communication equipment is also evolving; such as fiber optic distribution boxes. Fiber optic distribution boxes are distribution and splitting devices for user terminals in optical distribution network systems. They are devices that terminate, split, and distribute optical cables and fibers, and provide protection and management for optical cables.
[0003] Currently, the traditional fiber distribution boxes commonly used in the market mainly fix and organize optical fibers using cable ties or bundles. This fixing method has the advantages of simple operation and low cost, and can effectively separate and fix optical cables with different directions. However, since the cable tying process relies entirely on manual individual tying operations, it is not only time-consuming and labor-intensive but also inefficient. At the same time, when it is necessary to maintain or repair specific optical fibers, staff must locate the target optical fiber one by one and manually untie the cable ties, which is also time-consuming and labor-intensive, seriously affecting the efficiency of operation and maintenance. Utility Model Content
[0004] The purpose of this invention is to solve the problem of relying on manual individual bundling operations in the prior art, and to propose an optical fiber fixing mechanism and fiber distribution box.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A fiber optic fixing mechanism and fiber distribution box include a pair of support plates, a lifting plate that is vertically raised and lowered above the support plates, a mounting plate that is fixedly connected to the opposite side walls of the two lifting plates, a concave plate that is fixedly connected to the opposite side walls of the two support plates, and a plurality of limiting plates that are provided on the opposite sides of the mounting plate and the concave plate.
[0007] Also includes:
[0008] A drive assembly is mounted on the support plate and drives the two lifting plates to move up and down synchronously.
[0009] A movable component is disposed on the mounting plate, the movable component enabling one of the limiting plates on the mounting plate to move vertically independently.
[0010] Preferably, the drive assembly includes an L-shaped plate fixedly connected to the front of the support plate, a lifting screw rotatably connected to the L-shaped plate, the lifting plate and the lifting screw being threadedly connected, and a bevel gear being fixedly sleeved on the lifting screw.
[0011] Preferably, the drive assembly further includes the same transmission rod rotatably connected to the two L-shaped plates, with bevel gears two fixedly sleeved at both ends of the transmission rod, and the bevel gears two meshing with the bevel gear one.
[0012] Preferably, one end of the lifting screw extends below the L-shaped plate and is fixedly connected to a wheel.
[0013] Preferably, the top of the concave plate is threaded with a plurality of anti-detachment rods, and the top ends of the anti-detachment rods are fixedly connected to the limiting plate.
[0014] Preferably, the movable component includes a plurality of screws threaded to the mounting plate, a top block rotatably connected to the top of the screws, a slide rod fixedly connected to the bottom of the top block, and the slide rod and the mounting plate being vertically slidably connected.
[0015] Preferably, the bottom end of the slide rod extends to the opposite side of the mounting plate and the concave plate, and the bottom end of the slide rod is fixedly connected to the limiting plate.
[0016] Preferably, the tops of the two L-shaped plates are fixedly connected to the same baffle, and the baffle and the transmission rod are correspondingly arranged.
[0017] Preferably, it includes a housing on which an optical fiber fixing mechanism according to any one of claims 1-8 is installed.
[0018] Preferably, the back of the housing has an inlet hole, the front of the housing is movably connected to a sealing door via a hinge, and the sealing door has an outlet hole. A connecting block is fixedly installed on the vertical inner wall of the housing, and a guide plate is fixedly connected to the connecting block, with the guide plate and the inlet hole being correspondingly arranged.
[0019] Compared with the prior art, the advantages of this utility model are as follows:
[0020] 1. Through the setting of the drive component, the operator can use the rotary drive mechanism to make multiple sets of limiting plates on the mounting plate move vertically downward synchronously and fit tightly with the fiber array. The operation process is convenient and efficient. Only one rotation is needed to achieve synchronous limiting and clamping of multiple optical fibers, avoiding the tedious operation of one by one. The batch fixing not only ensures the clamping accuracy, but also improves the work efficiency.
[0021] 2. By setting up a movable component, when maintaining or removing a specific optical fiber, the corresponding top block is located first, and its screw is turned. The top block then moves vertically upward, which in turn moves the limiting plate at the bottom of the slide rod upward synchronously, releasing the limiting clamp on the optical fiber individually. This operation can effectively avoid releasing all optical fiber clamps during maintenance, preventing the optical fiber from becoming messy, and making optical fiber maintenance more precise and efficient.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0033] Reference Figures 1-4 An optical fiber fixing mechanism and fiber distribution box are disclosed, comprising a pair of support plates 1, each L-shaped. A lifting plate 2 is vertically raised and lowered above the support plates 1. A mounting plate 3 is fixedly connected to the opposite sidewalls of the two lifting plates 2. A concave plate 4 is also fixedly connected to the opposite sidewalls of the two support plates 1. The concave plate 4 is preferably, but not limited to, fixed by bolts to facilitate subsequent disassembly. The concave plate 4 is disassembled along with its limiting plates 5, and several limiting plates 5 are subsequently inspected, maintained, and replaced. Several limiting plates 5 are provided on opposite sides of the mounting plate 3 and the concave plate 4. The limiting plates 5 are arc-shaped to accommodate the optical fiber, ensuring a tight fit between the limiting plate 5 and the optical fiber for clamping and limiting.
[0034] Also includes:
[0035] A drive assembly is mounted on the support plate 1, and the drive assembly drives the two lifting plates 2 to rise and fall synchronously.
[0036] A movable component is mounted on the mounting plate 3, which allows one of the limiting plates 5 on the mounting plate 3 to move vertically independently.
[0037] The drive assembly includes an L-shaped plate 21 fixedly connected to the front of the support plate 1. A lifting screw 22 is rotatably connected to the L-shaped plate 21. The lifting plate 2 and the lifting screw 22 are threadedly connected. A bevel gear 23 is fixedly sleeved on the lifting screw 22. Under the action of the transmission rod 24, the two lifting screws 22 rotate in the same direction, thus ensuring that the two lifting plates 2 move vertically stably and synchronously. To ensure that the two lifting screws 22 rotate in the same direction, two lifting screws 22 with opposite thread rotation directions are pre-selected during installation, depending on the actual situation.
[0038] The drive assembly also includes the same transmission rod 24 rotatably connected to the two L-shaped plates 21. Both ends of the transmission rod 24 are fixedly fitted with bevel gears 25, which mesh with bevel gears 23.
[0039] One end of the lifting screw 22 extends below the L-shaped plate 21 and is fixedly connected to a rotating wheel 27. The rotating wheel 27 facilitates the rotation of the lifting screw 22 by the operator.
[0040] Several anti-detachment rods 51 are threadedly connected to the top of the concave plate 4, and the top of the anti-detachment rods 51 are fixedly connected to the limiting plate 5. The anti-detachment rods 51 are designed to be easily removed by the operator by screwing them off individually, thereby enabling the replacement of the limiting plate 5 with the anti-detachment rods 51, so that the curvature or size of the limiting plate 5 can be adapted to optical fibers of different sizes or thicknesses.
[0041] The movable component includes several screws 54 threaded onto the mounting plate 3. A top block 53 is rotatably connected to the top of each screw 54, and the top block 53 acts as a transmission mechanism, converting the rotation of the screws 54 into the vertical movement of the sliding rod 52, which drives the limiting plate 5. The bottom end of the top block 53 is fixedly connected to the sliding rod 52, and the sliding rod 52 and the mounting plate 3 are vertically slidably connected.
[0042] The bottom end of the slide rod 52 extends to the opposite side of the mounting plate 3 and the concave plate 4, and the bottom end of the slide rod 52 is fixedly connected to the limiting plate 5.
[0043] The tops of the two L-shaped plates 21 are fixedly connected to the same baffle 26, and the baffle 26 and the transmission rod 24 are correspondingly arranged. The baffle 26 is set to prevent the optical fiber from contacting the transmission rod 24 when it is led out, thus affecting the rotation of the transmission rod 24.
[0044] The housing 6 includes a fiber optic fixing mechanism according to any one of claims 1-8.
[0045] The back of the housing 6 has a cable inlet 61, and the front of the housing 6 is connected to a sealing door 62 via a hinge. The hinge connection of the sealing door 62 is a well-established technology and will not be described in detail here. The sealing door 62 has a cable outlet 63. A connecting block 64 is fixedly installed on the vertical inner wall of the housing 6, and a guide plate 65 is fixedly connected to the connecting block 64. The guide plate 65 and the cable inlet 61 are correspondingly arranged.
[0046] The functional principle of this utility model can be explained through the following operation methods:
[0047] First, the optical fiber to be fixed is introduced through the inlet hole 61 on the back of the housing 6, guided by the guide plate 65 to the space between the mounting plate 3 and the concave plate 4, and the optical fiber is then guided to be placed on the top of the limiting plate 5 on the concave plate 4.
[0048] The height of the lifting plate 2 and the mounting plate 3 is adjusted by the drive assembly so that the limiting plate 5 on the mounting plate 3 is close to the optical fiber. The rotating wheel 27 drives the lifting screw 22 to rotate. The first bevel gear 23 and the second bevel gear 25 mesh. Under the action of the transmission rod 24, the lifting screws 22 on both sides are driven synchronously to realize the synchronous lifting of the two lifting plates 2. This adjusts the vertical distance between the mounting plate 3 and the concave plate 4, so that the limiting plates 5 on the mounting plate 3 move vertically downward to position the optical fiber bundles of different specifications.
[0049] When maintaining or removing a single optical fiber, locate the corresponding top block 53, screw 54 on the top block 53, and after the screw 54 rotates, the top block 53 moves vertically upward under the guidance of the slide rod 52. The limiting plate 5 at the bottom of the slide rod 52 also moves vertically upward simultaneously, releasing the limiting clamp on the optical fiber and thus removing the optical fiber.
[0050] Finally, tidy up the fiber optic cable routing, store any excess cable inside the housing 6, close the sealing door 62, and lead the fiber optic cable out from the front outlet hole 63.
[0051] The entire process achieves batch positioning through the synchronous lifting and lowering of the drive components, completes the precise fixing and loosening of individual optical fibers through the single-point adjustment of the moving components, and achieves orderly placement and protection of optical fibers by combining the guide inside the housing 6.
[0052] 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.
