The first support outer cylinder 100 is integrally cylindrical, and the overall material is polybutylene terephthalate or modified polypropylene. A second support outer cylinder 101 is provided inside the first support outer cylinder 100. The specific material selection of the second support outer cylinder 101 is the same as that of the first support outer cylinder 100, and the thickness of the second support outer cylinder 101 is smaller than that of the first support outer cylinder 100. And a first installation space 102 is formed between the first support outer cylinder 100 and the second support outer cylinder 101.

The connection between the first support plate 201 and the bent support plate 202 is bent, and the bending direction of the bent support plate 202 is opposite to the bending direction of the connection between the first support plate 201 and the bent support plate 202. Moreover, the bent support plate 202 has a certain toughness, so that the bent support plate 202 itself can be bent, and the shape of the bent support plate 202 itself is a bent arc-shaped plate. The first support plate 201, the bent support plate 202 and the clamping support plate 203 are integrally provided. The bent support plate 202 bends and extends towards the second support outer cylinder 101, and a fitting 304 is provided at the connection between the first support plate 201 and the bent support plate 202.

[0040] Preferably, the connection between the first support plate 201 and the bent support plate 202 forms a protruding part protruding outwards. After protruding outwards, this protruding part forms a retaining edge and has a certain hardness as a whole.

[0041] Furthermore, in this embodiment, the second support member 300 includes a first support 301 provided on the outer side of the second support outer cylinder 101 and a second support 302 connected to the first support 301. The second support 302 extends outwards from the first support 301. The first support 301 is arranged around the outer wall of the second support outer cylinder 101.

[0042] Furthermore, the second support 302 is fixed to the first support 301. The second support 302 includes a number of arc plates 302a arranged in a circumferential array. The lower end of each arc plate 302a is connected to the protrusion. An installation notch 302b is formed between two arc plates 302a. The arc bending degree of the arc plate 302a is smaller than the bending degree of the bent support plate 202. At the same time, the extending direction of the arc plate 302a is arranged in the radial direction of the first support 301.

[0043] Preferably, every two adjacent arc plates 302a are arranged in opposite directions and are arranged close to each other. An installation notch 302b is formed between every two oppositely arranged arc plates 302a. The installation notch 302b is used for mating and docking with the first support member 200.

[0044] On the second bracket 302, there is a protruding member 303 that cooperates with the bent plate 202. The protruding member 303 is used to cooperate with the clamping plate 203 to achieve locking. In this embodiment, the protruding member 303 includes a bottom block 303a provided on the second bracket 302 and a mating flange 303b provided on the bottom block 303a. The mating flange 303b extends obliquely toward the end of the arc plate 302a away from the second bracket 302. A mating groove for cooperating with the clamping plate 203 is formed between the mating flange 303b and the bottom block 303a. When the clamping plate 203 cooperates with the mating groove, the clamping plate 203 will be clamped in the mating groove to form a stable connection structure.

[0045] Preferably, a clamping member that cooperates with the cooperating member 304 is provided on the bottom block 303a, and the cooperating member 304 is provided at the connection between the first plate 201 and the bent plate 202. The purpose of providing the clamping member and the cooperating member 304 is to be able to assist in protecting and supporting the optical fiber M.

[0046] Furthermore, in this embodiment, the cooperating member 304 includes a sliding groove 304a opened on the bent plate 202, a flexible sheet 304b movably connected in the sliding groove 304a, and an abutting head 304c provided at the front end of the flexible sheet 304b. The sliding groove 304a penetrates through the bent plate 202, and one end of the flexible sheet 304b is connected to the outer side surface of the bent plate 202 after passing through the sliding groove 304a. The other end of the flexible sheet 304b extends into the inside of the bent plate 202 and the end is close to the bottom block 303a. In this embodiment, the clamping member includes a top block 304d provided at the bottom block 303a near the mating flange 303b. An arc-shaped inclined surface is formed on the side of the top block 304d away from the mating groove, and the arc-shaped inclined surface is provided with a tapered inclined surface on the side close to the flexible sheet 304b, and a sheet-like protrusion is provided on the tapered inclined surface. A mating slot for cooperating with the sheet-like protrusion is opened on the flexible sheet 304b, and after the bent plate 202 is bent, the top block 304d abuts against the abutting head 304c.

[0047] After the bent plate 202 is bent, the clamping plate 203 is made to cooperate with the mating flange 303b on the bottom block 303a to complete the hanging connection. When hanging, the tapered inclined surface on the arc-shaped inclined surface is inserted into the flexible sheet 304b, and the connection is realized by using the sheet-like protrusion and the mating slot. After the connection, a double-insurance locking structure with the connection structure of the clamping plate 203 and the mating flange 303b and the connection structure of the flexible sheet 304b and the top block 304d is realized, thereby increasing the stability of the installation of the optical fiber M.

[0048] Further, an extended wrapping ring 400 is provided on the inner wall of the first shelf plate 201. There are two extended wrapping rings 400 on each first shelf plate 201. The ends of the two extended wrapping rings 400 away from the split shelf plate 200a are connected and form a protruding end 401. A bulging member 402 is provided at the connection between the extended wrapping ring 400 and the first shelf plate 201. In this embodiment, the bulging member 402 includes a folded line portion 402a provided at the connection between the first shelf plate 201 and the extended wrapping ring 400. The folded line portion 402a extends away from the first shelf plate 201, and a bulging space is formed between the two extended wrapping rings 400 and the first shelf plate 201.

[0049] A number of elastic strips 403 are wound around the inner side surface of the first support outer cylinder 100. Each elastic strip 403 is in a spiral winding state, and a number of elastic strips 403 are arranged side by side. A number of pressing blocks 404 are provided on the side surface of the elastic strip 403 away from the inner side of the first support cylinder. Each pressing block 404 corresponds to the first support member 200 one by one.

[0050] Preferably, the a number of elastic strips 403 are adhered to each other, and after spiral winding, the elastic strip 403 at the frontmost side is attached to the elastic strip 403 at the rearmost side.

[0051] The remaining structure is the same as that of Embodiment 1.

[0052] Operation process: When assembling the optical cable, the operator prefabricates the intermediate support member 103, then installs the second support outer cylinder 101. Then the operator installs the optical fiber M on the outside of the second support outer cylinder 101 according to a certain rule, and then installs the first support outer cylinder 100 to fix the optical fiber M. When installing the second support outer cylinder 101, the extended wrapping ring 400 on the second support outer cylinder 101 is inserted into the installation notch 302b between the arc plates 302a. When inserting, the optical fiber M will push open the protruding part, and then the bending shelf plate 202 is toggled away from the bottom block 303a. Then, as the first support outer cylinder 100 is continuously pressed in, the optical fiber M will gradually enter the space formed by the bending shelf plate 202. After the bending shelf plate 202 is bent, the clamping shelf plate 203 is matched with the mating flange 303b on the bottom block 303a to complete the hanging connection. When hanging, the tapered slope on the arc-shaped slope is inserted into the flexible sheet body 304b, and the connection is realized by using the sheet-shaped protrusion and the mating slot. After the connection, a double insurance locking structure with the connection structure of the clamping shelf plate 203 and the mating flange 303b and the connection structure of the flexible sheet body 304b and the top block 304d is realized, thereby increasing the installation stability of the optical fiber M.

[0053] And by using the elastic strip 403, when the optical cable is stretched ( Figure 5In the direction of the middle arrow), the elastic strip 403 will be tightened, thereby providing more stable support for the internal structure and achieving a gathering effect on the internal structure.

[0054] Example 3

[0055] Reference Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the previous embodiment in that: the present invention discloses an optical cable with a multi-cavity support structure, including a backbone 500. In this embodiment, the backbone 500 includes an optical cable support 501 arranged in the intermediate support member 103 and a buffer layer 502 arranged between the second support outer tube 101 and the first bracket 301.

[0056] Furthermore, an outer coating layer 504 is disposed on the outer side of the first supporting outer cylinder 100 , and the outer coating layer 504 is the outermost layer of the entire optical cable.

[0057] Furthermore, in this embodiment, the intermediate support member 103 includes a solid layer 103a arranged on the outside of the optical cable support 501, a core support 103b arranged outside the solid layer 103a, and a connecting member arranged on the core support 103b and connected to the first bracket 301, and an adhesive layer is arranged between the solid layer 103a and the optical cable support 501.

[0058] Furthermore, the connecting member includes a plurality of raised strips 103c arranged on the core pillar 103b and a matching recess 103d arranged on the first bracket 301 and matching with the raised strips 103c.

[0059] In this embodiment, the buffer layer 502 includes a plurality of flexible support strips 502a hinged end to end, a support block 502b arranged at the hinge of every two support strips, and a flexible rod 502c arranged on the support block 502b. The plurality of support blocks 502b are arranged in two rows, and the other end of the flexible rod 502c is connected to the end of the support block 502b in the other row. The support block 502b corresponds to the pressure block 404 one by one.

[0060] The remaining structures are the same as those in Example 2.

[0061] Operation process: The optical cable with a multi-cavity support structure is provided with a multi-layer structure, so that the optical cable as a whole can be more resistant to impact and pressure. At the same time, with the multi-cavity support structure, the optical cable as a whole has a certain overall strength and protects the internal optical fiber M. At the same time, the buffer layer 502 can also make the entire optical cable have a certain tensile performance.

[0062] Example 4

[0063] Reference Figure 7 and Figure 8, which is the second embodiment of the present invention. The difference between this embodiment and the previous one is that: further, the optical cable with a multi-cavity support structure further includes an end connection assembly. In this embodiment, the end connection assembly includes a joint cylinder 600 provided at the end of the outer cladding layer 504. It should be noted that the joint cylinder 600 is provided at the end of the entire optical cable and is directly fixed to the outer cladding layer 504. The outer cladding layer 504 and the joint cylinder 600 have the same diameter. A segmented sleeve 601 is also provided on the joint cylinder 600, and the segmented sleeve 601 can slide a certain distance on the joint cylinder 600, and the sliding direction can be away from or close to the outer cladding layer 504.

[0064] Further, an adhesion component is provided at the end of the joint cylinder 600. In this embodiment, the adhesion component includes a storage groove 602 opened on the joint cylinder 600, an extension rod 603 rotatably connected in the storage groove 602, and a discharge pipe 604 provided at the end of the extension rod 603. A folding rod 605 is hinged between the extension rod 603 and the storage groove 602. The hinged position of the extension rod 603 is set near the end side of the joint cylinder 600. Thus, the sliding of the segmented sleeve 601 will press the extension rod 603 into the storage groove 602, and a number of storage grooves 602 are opened and arranged in an annular array on the outside of the joint cylinder 600.

[0065] Further, in this embodiment, the folding rod 605 includes a first half rod 605a hinged to the middle section of the extension rod 603 and a second half rod 605b hinged to the first half rod 605a. A second torsion spring is provided between the first half rod 605a and the second half rod 605b. When the extension rod 603 rotates into the storage groove 602 under the sliding extrusion of the segmented sleeve 601, the second torsion spring will always drive the first half rod 605a and the second half rod 605b to change from the state of approaching each other to the state of moving away from each other, so that the extension rod 603 can be screwed out more quickly.

[0066] Preferably, an inner ring groove is opened at one end of the segmented sleeve 601 away from the outer cladding layer 504, and a friction layer is provided on the inner side of the segmented sleeve 601. A buckle groove matching with the discharge pipe 604 is provided in the inner ring groove.

[0067] The remaining structures are the same as those in Embodiment 3.

[0068] Operation process: When butt-joining and installing two optical cables, first align the two optical cables. Then, the operator pushes one of the segmented sleeves 601 towards the outer cladding layer 504, and slides the segmented sleeve 601 on the other optical cable away from the outer cladding layer 504. As the segmented sleeve 601 slides, the extension rod 603 is no longer blocked. Under the action of the second torsion spring, the first half rod 605a and the second half rod 605b change from the state of approaching each other to the state of moving away from each other, so as to screw the extension rod 603 out of the storage groove 602. Then, the discharge pipe 604 is installed in cooperation with the buckle groove, thus completing the butt-joint of the two optical cables.
