Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of optical cable installation equipment, and in particular relates to a protective cover for an indoor optical cable wall penetration hole. Background Art
[0002] When installing an optical cable through a wall, it is usually necessary to install a sleeve in the hole in the wall to protect the optical cable. The sleeve is divided into two parts. One part is passed through the wall, and the other part is assembled.
[0003] Since conventional wall penetration sleeves lack an elastic support structure, after the target optical cable passes through, the optical cable and the wall penetration sleeve are rigidly supported, causing the local bending amplitude of the optical cable to be too large, which makes it easy for conventional wall penetration sleeves to damage the optical fiber.
[0004] Therefore, we propose an indoor optical cable wall hole protective cover to solve the above problems. Utility Model Content
[0005] The utility model aims to solve the problem that conventional wall-penetrating sleeves are easy to damage optical fibers, and proposes a protective sleeve for indoor optical cable wall-penetrating holes.

[0008] Preferably, the threaded sleeve comprises a threaded sleeve body, and a clamping hole is formed in the middle of the threaded sleeve body. After drilling a hole in the target wall, the threaded sleeve body is passed through the target wall, and the threaded ring is screwed onto the threaded sleeve body, and the threaded ring is conveniently fixed to the threaded sleeve through the clamping hole.
[0009] Preferably, the threaded sleeve further comprises a first retaining ring, which is fixedly connected to the outside of the threaded sleeve body. After the threaded sleeve body passes through the target wall, the first retaining ring is used to block the outside of the target wall, so as to conveniently prevent the threaded sleeve from passing through the other side of the wall.
[0010] Preferably, the leather tube includes a tapered leather tube, a fixed leather block and an endothelial tube, wherein the tapered leather tube is symmetrically arranged at the outer end of the endothelial tube, and the tapered leather tube and the endothelial tube are an integrated structure, and the inner spaces of the tapered leather tube and the endothelial tube are connected. After the optical fiber passes through the tapered leather tube and the endothelial tube, the tapered leather tube is used to pad under the optical fiber, and the elastic force of the tapered leather tube is used to conveniently reduce the local bending amplitude of the optical fiber.
[0011] Preferably, the leather tube further comprises a leather ring, which is symmetrically arranged outside the endothelial tube, and the leather ring and the endothelial tube are an integrated structure. The elastic force of the leather ring is used to open the endothelial tube, thereby preventing the endothelial tube from being distorted inwards.
[0012] Preferably, the threaded ring includes a second retaining ring and a threaded ring body, wherein the second retaining ring is fixedly connected to the outer end of the threaded ring body. After the threaded sleeve penetrates the target wall, the threaded ring body is sleeved on the threaded sleeve, and then the second retaining ring is rotated to drive the threaded ring body to rotate, so that the threaded ring body is tightened on the threaded sleeve, which facilitates the assembly of the threaded sleeve and the threaded ring.
[0013] Preferably, the threaded ring further comprises a handle, which is evenly fixedly connected to the outside of the second retaining ring. When screwing the threaded ring, one hand is used to pinch the leather tube, and the other hand is used to pull the handle to revolve around the center of the threaded ring, and the second retaining ring is driven to rotate through the handle, so that the threaded ring can be rotated manually.
[0014] In summary, the technical effects and advantages of the utility model are as follows:
[0015] 1. First, drill a hole on the target wall, then pass the threaded sleeve through the target through-hole, then put the threaded ring on the outside of the threaded sleeve, pinch the leather tube with one hand, and then use the other hand to screw the threaded ring, tighten the threaded ring on the threaded sleeve, use the threaded sleeve and threaded ring to clamp the target wall, pass the target optical cable through the leather tube, use the leather tube to softly support the optical fiber, reduce the bending amplitude of the optical fiber, and facilitate the protection of the target optical fiber.
