Abstract
Description
Technical Field
[0001] This utility model relates to the field of signal transmission technology, specifically to an optical fiber tube. Background Technology
[0002] Commercially available fiber optic canisters typically have a simple structure, consisting of four parts: an outer shell, a cable extension rod, the main fiber optic cable, and a base housing the aerial terminal device. During use, they are usually connected to the drone using cable ties or straps. Furthermore, the main fiber optic cable inside the shell lacks a fixed positioning structure, making it prone to shaking and displacement during use, which can even lead to breakage. Additionally, if the internal fiber optic cable breaks or malfunctions, replacement and repair are difficult. Finally, a large proportion of fiber optic canisters on the market use external cables, resulting in low space utilization and increased weight. Utility Model Content
[0003] To solve the above technical problems, this utility model provides an optical fiber tube, which uses an optical fiber fixing device to press against the surface of the optical fiber buffer protective layer to fix the main optical fiber and prevent shaking and displacement during use.
[0004] The present invention adopts the following technical solution: An optical fiber tube, comprising: The fiber storage compartment has an internal cavity and at least one mounting hole on its surface. The main optical fiber is disposed within the receiving cavity and has an inner cylinder and an optical fiber disposed on the inner surface of the inner cylinder; An optical fiber buffer protective layer is wrapped around the surface of the inner cylinder; The fiber optic fixing device is installed on the mounting hole and pressed against the fiber optic buffer protective layer; An anti-entanglement guide rod for optical fibers is installed at the first end of the main fiber storage compartment. The fiber optic rear-view unit is located at the second end of the main fiber storage compartment. The main optical fiber is fixed by pressing it against the surface of the optical fiber buffer protective layer to prevent shaking and displacement during use. In addition, the main optical fiber can be taken out by unlocking and disassembling the optical fiber fixing devices on both sides and the optical fiber rear inspection unit at the bottom of the tube, which is convenient for analyzing optical fiber problems. If the optical fiber is exhausted, the main optical fiber can also be replaced according to the above instructions.
[0005] Preferably, the surface of the fiber storage main chamber is provided with two mounting holes at equal intervals, and each mounting hole is fitted with a fiber fixing device, which further prevents the main fiber from shaking by squeezing from both sides.
[0006] Preferably, the fiber anti-entanglement guide rod has a flared opening with a radius of curvature of 30mm, which conforms to the radius of curvature of the fiber.
[0007] Preferably, the fiber optic anti-entanglement guide rod has an arc-shaped structure, with the arc-shaped structure facing downwards to effectively avoid contact with the drone propeller.
[0008] Preferably, the end of the fiber optic anti-tangle guide rod is provided with a connector protection unit for fixing the fiber optic connector.
[0009] Preferably, the outer surface of the fiber storage main compartment is provided with a quick-connect part that connects to the drone body, enabling rapid connection with the drone body.
[0010] Preferably, the fiber optic rear-view unit is made of a transparent material, which allows for a clear view of the remaining fiber optic length and better judgment of the remaining working distance of the fiber optic cable.
[0011] Preferably, the fiber anti-tangle guide rod is connected to the fiber storage main chamber via a tenon and mortise snap fastener; or the fiber anti-tangle guide rod is connected to the fiber storage main chamber via a rotary lock; or the fiber anti-tangle guide rod is connected to the fiber storage main chamber via an elastic snap fastener.
[0012] Preferably, the optical fiber fixing device includes a snap-fit assembly, which includes a snap hook limiting member and a snap-fit block. The snap hook limiting member is disposed on the mounting hole, and the snap-fit block is connected to the snap hook limiting member.
[0013] Preferably, the fiber storage main compartment is provided with an inner lining block, and the connecting part of the inner lining block extends out from the mounting hole and is connected to the fiber fixing device.
[0014] Compared with the prior art, the present invention has the following advantages: 1. The fiber optic anti-tangle guide rod at the cable end is connected by a tenon and mortise snap-fit structure, which is directly inserted and fixed, making it easy to assemble and disassemble. The cable outlet is a flared opening, which conforms to the curvature radius of the fiber optic cable. The arc-shaped cable outlet facing downwards can effectively avoid contact with the drone propeller.
[0015] 2. There are two connection methods between the fiber optic tube and the drone. One is to fix it with conventional cable ties or straps, and to bind the fiber optic tube and the drone together by using the limiting groove on the fiber optic fixing device. The second is to use the quick-connect part reserved on the fiber optic tube, which allows the fiber optic tube to be quickly installed on the drone.
[0016] 3. By unlocking and disassembling the fiber optic fixing devices on both sides and the fiber optic rear inspection unit at the bottom of the cylinder, the main fiber optic cable can be taken out, which is beneficial for analyzing fiber optic problems. If the fiber optic cable is exhausted, the main fiber optic cable can also be replaced according to the above instructions.
[0017] 4. The remaining fiber optic cable can be clearly seen through the transparent optical fiber rear viewing unit at the bottom of the tube, making it easier to determine the remaining working distance of the fiber optic cable.
[0018] 5. The internal wiring structure can better utilize the overall structural space, reducing product volume and weight. Attached Figure Description

Detailed Implementation
[0032] To facilitate understanding of the technical solution of this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.
[0033] like Figure 1-2 As shown, an optical fiber tube includes a fiber storage main chamber 1, a main optical fiber 2, an optical fiber buffer protective layer 3, an optical fiber fixing device 4, an optical fiber anti-tangle guide rod 5, and an optical fiber rear inspection unit 6. The fiber storage main chamber 1 has an internal receiving cavity 1-1 and at least one mounting hole 1-2 on its surface. The main optical fiber 2 is disposed within the receiving cavity 1-1, having an inner cylinder and an optical fiber disposed on the inner surface of the inner cylinder. The optical fiber buffer protective layer 3 is wound around the surface of the inner cylinder. The optical fiber fixing device 4 is disposed on the mounting hole 1-2 and presses against the optical fiber buffer protective layer 3. The optical fiber anti-tangle guide rod 5 is disposed at the first end of the fiber storage main chamber 1. The optical fiber rear inspection unit 6 is disposed at the second end of the fiber storage main chamber 1. The optical fiber fixing device 4 presses against the surface of the optical fiber buffer protective layer 3 to fix the main optical fiber 2, preventing shaking and displacement during use. Furthermore, by unlocking and disassembling the optical fiber fixing devices 4 on both sides and the optical fiber rear inspection unit 6 at the bottom of the tube, the main optical fiber 2 can be removed for analysis of optical fiber problems. If the optical fiber is exhausted, the main optical fiber 2 can be replaced according to the above description.
[0034] Among them, the fiber optic buffer protective layer 3 can be made of flexible materials such as foam.
[0035] like Figure 3 As shown, the main optical fiber 2 is an internally placed fiber (i.e., the optical fiber is wound around the inner wall of the inner cylinder), which can make better use of the internal space of the optical fiber cylinder and reduce the weight of the optical fiber cylinder.
[0036] The surface of the fiber storage main chamber 1 is provided with two mounting holes 1-2 at equal intervals. Each mounting hole 1-2 is fitted with an optical fiber fixing device 4, which further prevents the main optical fiber 2 from shaking by squeezing from both sides.
[0037] In existing technologies, the cable delivery opening of fiber optic tubes is generally a relatively regular circular opening without a transition structure. Fiber optic cables require a certain radius of curvature to stabilize signal transmission, and there is a risk of the cable getting entangled in the drone's propeller during delivery, potentially causing a crash. For example... Figure 4 As shown, in this embodiment, the fiber optic anti-entanglement guide rod 5 has a flared opening 5-1 with a radius of curvature of 30mm, which conforms to the radius of curvature of the optical fiber. The fiber optic anti-entanglement guide rod 5 is used to extend the cable laying distance and avoid entanglement with the drone propeller; the rod body of the fiber optic anti-entanglement guide rod 5 has an arc-shaped structure, and the downward-facing arc structure can effectively avoid contact with the drone propeller.
[0038] The end of the fiber optic anti-tangle guide rod 5 is provided with a connector protection unit 7 for fixing the fiber optic connector head, and the connector protection unit 7 can use a rubber plug.
[0039] In existing technologies, fiber optic tubes and drones lack a fixed structure and are typically secured with cable ties or straps, which is inconvenient. For example... Figure 5 As shown, in this embodiment, in addition to the conventional cable ties or straps used in the prior art, the outer surface of the fiber storage main compartment 1 is provided with a quick-connect part 1-3 that connects to the drone body, which enables quick connection with the drone body.
[0040] The fiber optic rear-view unit 6 is made of transparent material, allowing a clear view of the remaining fiber optic length and better assessment of the remaining working distance. Furthermore, the transparent fiber optic rear-view unit 6 can secure the drone's aerial end, accommodate fusion splice connectors, and check fiber optic length. This reduces wind resistance during drone flight, conserves power, and allows for easy replacement.
[0041] like Figure 6 As shown, the fiber anti-tangle guide rod 5 is connected to the fiber storage main chamber 1 by a tenon and mortise snap fastener. The fiber storage main chamber 1 is provided with a first snap connector 1-4, and the fiber anti-tangle guide rod 5 is provided with a matching second snap connector 5-2.
[0042] Or such as Figure 7-8 As shown, the fiber anti-tangle guide rod 5 is connected to the fiber storage main chamber 1 by a rotary lock. The fiber storage main chamber 1 is provided with an L-shaped groove 1-5, and the fiber anti-tangle guide rod 5 is provided with a matching locking block 5-3. In use, the locking block 5-3 is inserted from one end of the L-shaped groove 1-5, and then the fiber anti-tangle guide rod 5 is rotated to lock the fiber anti-tangle guide rod 5 to the fiber storage main chamber 1. Or such as Figure 9 As shown, the fiber anti-tangle guide rod 5 is connected to the fiber storage main chamber 1 by an elastic snap fastener. The fiber storage main chamber 1 is provided with a limiting block 1-6, and the fiber anti-tangle guide rod 5 is provided with an elastic clip 5-4. The elastic clip 5-4 is provided with a connecting groove that matches the limiting block 1-6. When the fiber anti-tangle guide rod 5 is connected to the fiber storage main chamber 1, the elastic clip 5-4 presses against the outside of the limiting block 1-6 and the limiting block 1-6 is embedded in the connecting groove.
[0043] like Figure 10 As shown, the optical fiber fixing device 4 includes a buckle assembly, which includes a hook limiting member 4-1 and a buckle pressing block 4-2. The hook limiting member 4-1 is disposed on the mounting hole 1-2, and the buckle pressing block 4-2 is connected to the hook limiting member 4-1.
[0044] like Figure 11-12 As shown, the fiber storage main compartment 1 is provided with an inner lining block 8. The connecting part 8-1 of the inner lining block 8 extends out from the mounting hole 1-2 and is connected to the optical fiber fixing device 4.
[0045] The above are merely preferred embodiments of this utility model. The scope of protection of this utility model is defined by the scope of the claims. Any improvements and modifications made by those skilled in the art without departing from the spirit and scope of this utility model should also be considered as protection within the scope of this utility model.
