The slide groove 304a passes through the bending frame plate 202, and one end of the flexible sheet 304b is connected to the outer side of the bending frame plate 202 after passing through the slide groove 304a. The other end of the flexible sheet 304b extends into the inner side of the bending frame plate 202, and the end The part is close to the bottom block 303a. In this embodiment, the clamp includes a top block 304d arranged at the bottom block 303a near the matching flange 303b. The side of the top block 304d away from the matching groove forms an arc-shaped inclined surface, and this arc-shaped inclined surface is close to the side of the flexible sheet 304b and is arranged into a conical inclined surface. A sheet-like protrusion is arranged on the conical inclined surface, and a matching groove that matches the sheet-like protrusion is opened on the flexible sheet 304b. After the bending frame plate 202 is bent, the top block 304d abuts against the abutment head 304c.

[0047] After the bending frame plate 202 is bent, the snap-on frame plate 203 is matched with the matching flange 303b on the bottom block 303a to complete the hanging. During the hanging, the tapered inclined surface on the arc-shaped inclined surface is clamped into the flexible sheet 304b, and the sheet-like protrusion and the matching groove are used to achieve connection. After the connection, a double-safety locking structure is realized with the connection structure between the snap-on frame plate 203 and the matching flange 303b, and the connection structure between the flexible sheet 304b and the top block 304d, thereby increasing the stability of the installation of the optical fiber M.

[0048] Furthermore, an extension ring 400 is provided on the inner wall of the first frame plate 201, and two extension rings 400 are provided on each first frame plate 201. The two extension rings 400 are connected at one end away from the petal frame plate 200a, and form a protruding end 401.

[0051] The rest of the structure is the same as that of Example 1.

[0052] Operation process: When assembling the optical cable, the operator pre-makes the intermediate support member 103, and then installs the second support outer cylinder 101. Then, the operator installs the optical fiber M outside the second support outer cylinder 101 according to a certain pattern, and then installs the first support outer cylinder 100 to fix the optical fiber M. When installing the second support outer cylinder 101, the extension ring 400 on the second support outer cylinder 101 is inserted into the installation notch 302b between the arc plates 302a. When inserted, the optical fiber M will push open the protruding part, and then the bending frame plate 202 is pushed away from the bottom block 303a, and then with the first support outer cylinder 101, the optical fiber M is fixed. As the supporting outer cylinder 100 is continuously pressed in, the optical fiber M will gradually enter the space formed by the bending frame plate 202. After the bending frame plate 202 is bent, the snap-fit frame plate 203 is engaged with the matching flange 303b on the bottom block 303a to complete the hanging. During the hanging, the tapered inclined surface on the arc-shaped inclined surface is engaged with the flexible sheet 304b, and the connection is achieved by using the sheet-like protrusion and the matching groove. After the connection, a double-safety locking structure is realized with the connection structure between the snap-fit frame plate 203 and the matching flange 303b, and the connection structure between the flexible sheet 304b and the top block 304d, thereby increasing the stability of the installation of the optical fiber M.

The support blocks 502b correspond one-to-one to the pressure blocks 404.

[0060] The rest of the structure is the same as that of 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 completes the protection of the internal optical fiber M. At the same time, the buffer layer 502 can also give the entire optical cable a certain tensile performance.

[0062] Example 4

[0063] Reference Figure 7 and Figure 8, which is the second embodiment of the present invention. This embodiment is different from the previous embodiment in that: further, the optical cable with a multi-cavity support structure also includes an end connection assembly. In this embodiment, the end connection assembly includes a connector barrel 600 arranged at the end of the outer coating layer 504. It is worth noting that the connector barrel 600 is arranged at the end of the entire optical cable and is directly fixed to the outer coating layer 504. The diameter of the outer coating layer 504 is consistent with that of the connector barrel 600. A segmented sleeve 601 is also provided on the connector barrel 600.

In the present embodiment, the adhesive component includes a storage groove 602 opened on the connector tube 600, an extension rod 603 rotatably connected in the storage groove 602, and a discharge pipe 604 arranged at the end of the extension rod 603. A broken line rod 605 is hinged between the extension rod 603 and the storage groove 602. The hinge position of the extension rod 603 is set near the end side of the connector tube 600, and then the sliding of the segmented sleeve 601 will press the extension rod 603 into the storage groove 602. A plurality of storage grooves 602 are opened, and a ring array is arranged on the outside of the connector tube 600.

[0065] Furthermore, in this embodiment, the folded-line 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 is rotated into the storage slot 602 after being squeezed by the sliding 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 a state of approaching each other to a state of moving away from each other, thereby making the extension rod 603 rotate out faster.

[0066] Preferably, an inner annular groove is provided in one end of the segmented sleeve 601 away from the outer coating layer 504 , and a friction layer is provided on the inner side of the segmented sleeve 601 , and a buckle groove cooperating with the discharge pipe 604 is provided in the inner annular groove.

[0067] The rest of the structure is the same as that of Example 3.

[0068] Operation process: When docking and installing two sections of optical cables, first align the two optical cables, and then the operator pushes one of the segmented sleeves 601 toward the outer coating 504, and slides the segmented sleeve 601 on the other optical cable toward the outer coating 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 are driven from a state of being close to each other to a state of being away from each other, thereby rotating the extension rod 603 out of the storage slot 602, and then allowing the discharge pipe 604 to be installed in conjunction with the buckle slot to complete the docking of the two sections of optical cables.
