Description

Technical Field

[0001] This utility model relates to the field of optical fiber protection, and in particular to a protection device for optical fiber lines. Background Technology

[0002] Protecting optical fibers is an important task to ensure their normal operation and extend their service life. Optical fibers are very sensitive to bending, so during installation and use, it is important to avoid bending the optical fibers to a degree that exceeds the specified radius. This helps to prevent the loss of optical signals and damage to the optical fibers.

[0003] Currently, in order to prevent optical fibers from bending excessively during use, a circular protective shell is often set on the outside of the optical fiber, and staggered blocking plates are set on the outside of each pair of adjacent circular protective shells. This ensures that the optical fiber has a certain degree of bending ability while preventing excessive bending, thereby ensuring the normal use of the optical fiber.

[0004] While existing protective shells can protect optical fibers to some extent and prevent excessive bending, in actual use, some of the blocking plates deform due to the bending of the optical fiber. Therefore, after long-term use, the deformed area is prone to damage, and the protective effect on the optical fiber is reduced. To address this problem, a protective device for optical fiber lines is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a protection device for optical fiber lines, which aims to improve the problem in the prior art that the protection device is easily deformed after the optical fiber is bent, resulting in damage and affecting the protection effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a protective device for optical fiber lines, comprising a protective shell, a protective ring fixedly connected to the outer wall of the protective shell, a protective mechanism jointly provided inside and outside the protective ring, the protective mechanism comprising a direction-limiting component, the direction-limiting component comprising a blocking plate, the inner arc surface of the blocking plate being fixedly connected to the outer wall of the protective shell, the protective mechanism further comprising an arc-limiting component, the arc-limiting component protecting a mounting groove, the mounting groove being formed in the inner wall of the protective ring, a mounting tube fixedly connected to the inner wall of the mounting groove, a pneumatic pipe fixedly connected to the inner wall of the mounting tube, a piston plate piston-connected to the inner wall of the mounting tube, the outer wall of the piston plate being elastically connected to the inner wall of the mounting tube by a spring.

[0007] As a further description of the above technical solution:

[0008] The number of protective rings is set to multiple, and the distance between any two adjacent protective rings is the same. The left and right ends of the blocking plate are respectively fixedly connected to the ends of the two adjacent protective rings that are close to each other.

[0009] As a further description of the above technical solution:

[0010] The width of the blocking plate is the same as the distance between any two adjacent protective rings, and two blocking plates are provided between every two adjacent protective rings.

[0011] As a further description of the above technical solution:

[0012] Each piston plate has two springs on its exterior, one on the left and one on the right.

[0013] As a further description of the above technical solution:

[0014] The mounting tube is made of rigid material, the air pressure tube is made of flexible material, and both the mounting tube and the air pressure tube are airtight.

[0015] As a further description of the above technical solution:

[0016] The piston plate is cylindrical in shape, and the outer wall of the piston plate is in contact with the inner wall of the mounting tube.

[0017] As a further description of the above technical solution:

[0018] Each of the protective rings has two mounting tubes inside, and the angle between the mounting tubes and the blocking plate is ninety degrees.

[0019] As a further description of the above technical solution:

[0020] The inner side of the blocking plate is set to an arc shape that matches the curvature of the outer wall of the protective shell, and the outer side of the blocking plate is set to an arc shape that matches the curvature of the protective ring.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up the installation tube, the air pressure tube, the piston plate and the spring, it is ensured that the optical fiber line is in the same area near the protection ring, and it is not easy for large bending sections to occur continuously. Since the air pressure tube itself has the ability to deform, it is not easy to be damaged. Thus, it is ensured that the optical fiber line will not be bent to a large extent, thereby achieving the effect of protecting the optical fiber line and not easily damaging the protective object.

[0023] 2. In this utility model, by setting the blocking plate, it is ensured that the bending direction of the optical fiber line is unique when it is bent, thereby ensuring that the blocking plate is not easily deformed when the optical fiber line is bent. At the same time, it ensures that the deformation of the air pressure tube can be affected to the greatest extent when the optical fiber line is bent, so as to achieve the effect of ensuring protection.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a protective device for optical fiber lines, comprising a protective shell 1, the protective shell 1 being tubular in shape and made of flexible material, the inner wall of the protective shell 1 being fixedly connected to the outer wall of the optical fiber, and a protective ring 2 being fixedly connected to the outer wall of the protective shell 1, the number of protective rings 2 being set to multiple, the distance between any two adjacent protective rings 2 being consistent, the protective ring 2 being circular in shape, and the inner diameter of the protective ring 2 matching the outer diameter of the protective shell 1.

[0031] Reference Figure 1 - Figure 3The protective ring 2 has a protective mechanism 3 both inside and outside. The protective mechanism 3 includes a direction-limiting component 31, which includes a blocking plate 311. The blocking plate 311 is used to prevent the protective shell 1 and its internal optical fibers from bending at their respective locations, thereby limiting the bending direction of the optical fibers. The inner arc surface of the blocking plate 311 is fixedly connected to the outer wall of the protective shell 1. The blocking plate 311, the protective shell 1, and the protective ring 2 are integrally formed. The left and right ends of the blocking plate 311 are respectively fixedly connected to the adjacent ends of two adjacent protective rings 2. The width of the blocking plate 311 is equal to that of the two adjacent protective rings 2. The distance between adjacent protection rings 2 is consistent, and two blocking plates 311 are provided between every two adjacent protection rings 2. The number of blocking plates 311 is set to ensure that the optical fiber line can bend only in the direction perpendicular to the two blocking plates 311, thereby ensuring that the deformation of the blocking plates 311 is small when the equipment bends, reducing the probability of damage to the blocking plates 311 due to deformation. The inner side of the blocking plate 311 is set to be an arc shape consistent with the curvature of the outer wall of the protective shell 1, and the outer side of the blocking plate 311 is set to be an arc shape consistent with the curvature of the protection ring 2. The shape of the blocking plate 311 is set.

[0032] Reference Figure 1 - Figure 3 The protection mechanism 3 also includes an arc-limiting component 32, which protects the mounting groove 321. The mounting groove 321 is formed on the inner wall of the protection ring 2. An mounting tube 322 is fixedly connected to the inner wall of the mounting groove 321. The mounting tube 322 is hollow cylindrical. An air pressure tube 323 is fixedly connected to the inner wall of the mounting tube 322. The diameter of the air pressure tube 323 is smaller than the diameter of the mounting tube 322. Two mounting tubes 322 are provided inside each protection ring 2. The angle between the mounting tube 322 and the blocking plate 311 is 90 degrees. The mounting tube 322 is made of rigid material, and the air pressure tube 323 is made of flexible material. Each air pressure tube 323 is fixedly connected to two adjacent mounting tubes 322 in the left-right direction. The internal connection is complete, and both the mounting tube 322 and the air pressure tube 323 are airtight. The inner wall of the mounting tube 322 is connected to a piston plate 324. The initial position of the piston plate 324 is set in the middle of the mounting tube 322. The piston plate 324 is cylindrical in shape, and the outer wall of the piston plate 324 is in contact with the inner wall of the mounting tube 322. By contacting the piston plate 324, it is ensured that the gas will not flow through the gap between the piston plate 324 and the mounting tube 322. Two springs 325 are provided on the outside of each piston plate 324. The two springs 325 are respectively set at the left and right ends of the piston plate 324. The elastic force of the two springs 325 is consistent. The outer wall of the piston plate 324 and the inner wall of the mounting tube 322 are elastically connected by the springs 325.

[0033] Working principle: When in use, due to the setting of the blocking plate 311, when the optical fiber line needs to be bent to a certain extent, the resistance that the optical fiber line needs to overcome when deforming at the location of the blocking plate 311 is large. Therefore, the bending position of the optical fiber line is perpendicular to it, that is, the bending position is at the location of the air pressure pipe 323.

[0034] When the optical fiber line bends, the air pressure tube 323 at the bend position is indented inward due to external force. As a result, the space formed between the piston plates 324 in the mounting tube 322 connected to the left and right sides of the air pressure tube 323 becomes smaller. Therefore, under the action of air pressure, both piston plates 324 move away from the air pressure tube 323.

[0035] After the piston plate 324 moves, the gas pressure inside the air pressure pipe 323 adjacent to the bent air pressure pipe 323 increases. Therefore, the resistance that the air pressure pipe 323 needs to overcome to deform increases, so the air pressure pipe 323 is not easy to bend.

[0036] Although the pressure pipe 323 adjacent to the curved pressure pipe 323 is not prone to deformation, its internal pressure still increases due to the gas inside the curved pressure pipe 323 pushing the piston plate 324. Therefore, the internal gas also pushes the adjacent piston plate 324, and so on. Thus, the resistance that the pressure pipe 323 near the deformed pressure pipe 323 needs to overcome to deform decreases in turn.

[0037] Since the pressure pipe 323 adjacent to a bent pressure pipe 323 has the greatest resistance to overcome when bending, it is not easy for it to bend at that position. Therefore, the optical fiber line is not easy to bend significantly at a relatively close position, thus achieving the effect of protecting the optical fiber.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
