[0002] Optical fiber is the abbreviation of optical fiber, which is a fiber made of glass or plastic that can be used as a light transmission tool. With the maturity and development of optical fiber technology, optical fiber has entered people's daily lives. In daily life, since the conduction loss of light in optical fiber is much lower than the conduction loss of electricity in wires, optical fiber is used for long-distance information transmission.

[0003] Nowadays, fiber optic devices are often used to lay fiber optic lines underground, and then divide them for users to use.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Example 1

[0031] Reference Figure 1-5 , an optical fiber device with a protection mechanism, comprising an optical fiber cable 1, a protection mechanism distributed along the optical fiber cable 1 is arranged on the periphery of the optical fiber cable 1, the protection mechanism is provided with a protection seat 2 with four bending structures, an air bag 4 is fixed in the middle position of the protection seat 2, and an air pipe 401 connected with the air bag 4 is embedded and fixed on the outer wall of the protection seat 2, both sides of the inner wall of the protection seat 2 are provided with a movable locking mechanism, the locking mechanism is in contact with the side wall of the air bag 4, the expansion of the air bag 4 pushes two adjacent locking mechanisms closer, both sides of the protection seat 2 are provided with installation grooves, and the inner wall of the installation groove is fixed with a magnetic block 3, and the two adjacent magnetic blocks 3 are magnetically adsorbed;

[0032] When using the protection mechanism, four sets of protection seats 2 are buckled onto the periphery of the optical fiber cable 1, and the magnetic block 3 is used for pre-fixation so that the optical fiber cable 1 is covered in the protection mechanism. The airbag 4 is inflated through the air tube 401 so that the outer wall of the airbag 4 squeezes the optical fiber cable, so that the protection seat 2 and the airbag 4 are used to provide protective protection for the optical fiber cable 1, and the deformable performance of the airbag 4 is used to allow the optical fiber cable 1 to be slightly deformed in the protection seat 2, thereby ensuring the use effect while avoiding excessive bending of the optical fiber, and the inflated airbag 4 is used to make the two adjacent locking mechanisms buckle, so as to achieve the effects of protective protection and sealing buckling at the same time, and the airbags 4 at the four corners are used to squeeze the locking mechanisms so that the protection seats 2 are squeezed against each other, thereby improving the actual sealing protection effect of the internal optical fiber cable 1, thereby improving the protection effect of the optical fiber and extending the service life of the optical fiber.

[0033] In the present invention, corresponding locking mechanisms are provided at the four corners of both ends of the protection seat 2, and the locking mechanisms correspond to the positions of the airbags 4. Two adjacent protection mechanisms are connected by the locking mechanisms, so that the locking mechanisms at both ends are moved by the airbags 4 to connect multiple protection mechanisms. By splicing multiple protection mechanisms, complete protection of the optical fiber cable 1 is achieved. In combination with the protection mechanism formed by splicing four protection seats 2, the airbags 4 can be used to facilitate the rapid disassembly of a single protection seat 2 at a certain position to inspect the internal optical fiber cables, thereby improving the actual use effect.

[0034] In the present invention, equidistantly distributed protrusions 402 are fixed at positions on the outer wall of the airbag 4 corresponding to the optical fiber cable 1, and the outer wall of the protrusion 402 is set to an arc structure, and a streamline groove is set between two adjacent protrusions 402. During use, the airbag 4 is inflated to squeeze the protrusion 402 and the streamline groove on the outer wall of the optical fiber cable 1. While ensuring stable protection for the optical fiber cable 1, air circulation on the outer wall of the optical fiber cable 1 can be ensured, thereby improving the heat dissipation and cooling effect of the optical fiber cable 1. The irregular surfaces of the protrusion 402 and the streamline groove are used to make the force of the airbag feedback to the locking mechanism different, so that the two adjacent locking mechanisms are tilted to one side, so as to increase the overall stability and sealing effect of the protection mechanism, and enhance the actual protection effect of the optical fiber cable 1.

[0035] In the present invention, a slide groove 6 is provided at a position corresponding to the inner wall of the protection seat 2 and the locking mechanism, and the locking mechanism is provided with a connecting plate 5 slidably connected to the inner wall of the slide groove 6, the connecting plate 5 is fixed at one end close to the magnetic block 3, the connecting plate 5 is rotatably connected to a connecting rod 8 at one side close to the airbag 4, the connecting rod 8 is rotatably connected to a contact plate 7 at one end away from the connecting plate 5, the contact plate 7 is rotatably connected to the inner wall of the protection seat 2 at one end away from the magnetic block 3, and the outer wall of the contact plate 7 at one side away from the connecting rod 8 contacts the outer wall of the airbag 4;

[0037] The airbag 4 swells up to squeeze the contact plate 7 and push the connecting plate 5 toward the magnetic block 3 through the connection of the connecting rod 8, so that the blocks 501 and the slots 502 on the two adjacent connecting plates 5 are engaged with each other. When the forces on the two connecting plates 5 are different, the connecting plates 5 slide directly into the slots 6 on the side with less force, and the sealing protection effect of the protection mechanism is improved with the blocks 501 and the slots 502 distributed at intervals.

[0038] In the present invention, the outer wall of the contact plate 7 on one side away from the connecting rod 8 is provided with auxiliary grooves 701 distributed at equal distances, and the auxiliary grooves 701 extend along the moving direction of the connecting plate 5, and the inner wall of the auxiliary grooves 701 is arranged to be an arc structure, and the auxiliary grooves 701 are penetrated at one end away from the fixed point of the contact plate 7, so that the optical fiber cable 1 is further prevented from being pressed tightly and airtight by using multiple auxiliary grooves 701, thereby improving the actual heat dissipation and cooling effect of the optical fiber cable 1 and extending the service life of the optical fiber device.

[0040] S1: Select and use a set of four protection seats 2, snap the four protection seats 2 into place at the four outer corners of the corresponding positions of the optical fiber cable 1, and use the magnetic block 3 to pre-fix the four protection seats 2 to form a protection mechanism;

[0041] S2: The corresponding four protection seats 2 are also buckled at both ends of the protection mechanism, and the two protection mechanisms are closely contacted with each other. Then, the airbag 4 in the protection mechanism at the middle position is inflated through the air pipe 401, so that the airbag 4 squeezes the optical fiber cable. The inflated airbag 4 pushes the connecting plate 5 to make the clamping block 501 overlap with the corresponding position clamping groove 502;

[0042] S3: Continue to splice the protection mechanism to the other end of the protection mechanism where the airbag 4 is not inflated, and then inflate the airbag in the protection mechanism at the middle position until the outer wall of the optical fiber cable 1 is completely protected by the protection mechanism, and buckle the limiting buckles at both ends of the overall protection mechanism to fix the limiting buckles to the optical fiber cable 1, and limit and fix the protection mechanisms at both ends by the limiting buckles;

[0043] S4: Lay other optical fiber cables 1 from the four sides of the laid optical fiber cable 1 , and use the first connecting strip 9 and the second connecting strip 10 to make two adjacent optical fiber cables 1 close to each other.

The interval arrangement of the first connecting strip 9 and the second connecting strip 10 ensures the stability of the overall optical fiber device after the cables are arranged, and facilitates the sliding removal of a single protective seat 2 from various positions on the periphery for maintenance, thereby enhancing the protection effect and improving the convenience of use.
