Description

Technical Field

[0001] The utility model belongs to the field of optical cable laying guide devices, and in particular relates to an optical cable laying guide device used in a pipeline. Background Art

[0002] Optical cable is a communication cable used to transmit optical signals. It is mainly composed of optical fiber (optical fiber) and is wrapped with a protective casing and sheath on the outside. Optical cables are usually buried underground. In order to protect the safety of optical cables, they are usually laid in pre-installed underground pipes. In the use of existing technologies, a traction device is usually required to assist in the wiring of optical cables. Due to the complex bends of the pipes buried underground and the large friction between the optical cables and the pipes, it is inconvenient to wire the optical cables in the pipes. In addition, the fixing of the optical cables by the guiding device is unstable and it is easy to be disconnected from the optical cables during the guiding process. Utility Model Content

[0009] Preferably, the clamping assembly includes a screw sleeve, a second groove body, a third groove body and a sleeve nut; a screw sleeve is fixedly connected to one end of the evenly distributed first fixing block close to the axis of the fixing ring; the outer wall of the screw sleeve is penetrated by a second evenly distributed groove body; the end of the screw sleeve that fits with the first fixing block is provided with a third groove body; the outer wall of the screw sleeve is threadedly mounted with a sleeve nut; the outer wall of the sleeve nut fits with the inner wall of the third groove body, the sleeve nut is inserted into the outer wall of the screw sleeve, and then the optical cable is inserted into the inner wall of the screw sleeve, and then the sleeve nut is rotated to make the sleeve nut rotate toward the end where the two screw sleeves are close to each other, thereby fixing the optical cable on the inner wall of the screw sleeve, and by providing two screw sleeves and sleeve nuts, the optical cable can be more stably fixed on the two fixing rings.

The fixed column can rotate when the two fixing rings are connected, thereby improving the connectivity between the two fixing rings.

[0011] Preferably, the upper end of the fixing ring is trapezoidal; the connecting belt is made of rubber, which can avoid the problem of excessive bending and deformation of the connecting belt when passing through a curved pipe.

[0012] Beneficial effects of the utility model:

[0013] 1. The outer wall of the pulley on the second fixed block is fitted with the inner wall of the pipeline; the friction of the optical cable when sliding on the inner wall of the pipeline can be appropriately reduced, so that the laying of the optical cable in the pipeline can be facilitated, and the problem of large friction between the pipeline and the optical cable, which makes it inconvenient to lay the optical cable;
