Abstract
The utility model discloses a connecting structure of casing of optical fiber on wall used for connection of casing of communication cable in order to solve bad seal of connection between prior casings of optical fiber on wall; the utility model provides a pipe connecting parts, shape of inner wall of the pipe connecting parts is matched with shape of outer wall of the casing of optical fiber on wall, inner diameter of the pipe connecting parts is slightly larger than outer diameter of the casing of optical fiber on wall, inner diameters at both ends of the pipe connecting parts are expanded, a seat cover is fixedly sleeved with outer wall of one end of the casing of optical fiber on wall, one end of the seat cover forms a block edge which is utilized to determine depth of the casing of optical fiber on wall inserted into the pipe connecting parts(i.e. mark of inserted depth), end of the casing of optical fiber is inserted into one end of the pipe connecting parts, the block edge is attached to outer edge of the end of the pipe connecting parts, and the seat cover can just clamp the casing of optical fiber on wall and the pipe connecting parts. Therefore, connection of the casing of the optical fiber on wall is sealed well, and the casing of the optical fiber on wall is easy to be laid.
Description
Affiliated technical field
The utility model relates to a kind of laying communications cable protecting pipe.
Background technology
At present, when burying cable (being generally optical cable) underground, need use cable sheath tube in order to protect cable, specific practice is: lay light wall cable sheath tube earlier, comprise outer tube and interior pipe, in the pipe, do the protection that is beneficial to cable like this in then cable being penetrated; But at present being connected between light wall cable sheath tube and the light wall cable sheath tube exists sealing not good, makes the phenomenon that seeps water to occur, and can shorten the useful life of cable like this, and cause cable fault easily.
Summary of the invention
In order to overcome the not good deficiency of existing smooth wall cable cover(ing) pipe connecting structure sealing, the utility model provides a kind of smooth wall cable cover(ing) pipe connecting structure, and this syndeton makes that the sealing of two smooth wall cable sheath tube junctions is fine.
The utility model for the technical scheme that solves its technical problem and adopt is: be provided with a pipe connecting piece, pipe connecting piece inner wall shape and light wall cable sheath tube outer wall shape are complementary, the pipe connecting piece internal diameter is a bit larger tham light wall cable cover(ing) external diameter of pipe, pipe connecting piece two ends internal diameter enlarges, the light wall cable cover(ing) pipe end outer wall fixed cover cover of choosing a place to give a banquet, in the light wall cable cover(ing) pipe end insertion tube fitting, the part cover for seat is in the gap that pipe connecting piece enlarges inwall behind the internal diameter and light wall cable sheath tube outer wall.
Cover for seat one end forms the retaining edge, this retaining edge is close to pipe connecting piece port outer, be used for determining the degree of depth (being the insertion depth mark) of light wall cable sheath tube insertion tube fitting, the other end is provided with sealing ring, and sealing ring is in the gap that pipe connecting piece enlarges inwall behind the internal diameter and light wall cable sheath tube outer wall.
The retaining edge equals 1/2nd of pipe connecting piece length from the distance of light wall cable cover(ing) pipe end.
The beneficial effects of the utility model are, in light wall cable sheath tube insertion tube fitting opening, part cover for seat and sealing ring enter in the pipe connecting piece simultaneously, be close to pipe connecting piece port outer until the retaining edge, this retaining edge is used for determining the degree of depth of light wall cable sheath tube insertion tube fitting, and this time wall cable sheath tube and pipe connecting piece seal chucking just.Therefore, the sealing of light wall cable sheath tube junction is fine, the phenomenon that seeps water can not occur like this, and also lay cable easily.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Embodiment
Embodiment: referring to Fig. 1, a kind of smooth wall cable cover(ing) pipe connecting structure, be provided with a pipe connecting piece 1, pipe connecting piece 1 inner wall shape and light wall cable sheath tube 2 outer wall shapes are complementary, pipe connecting piece 1 internal diameter is slightly larger than light wall cable sheath tube 2 external diameters, and pipe connecting piece 1 two ends internal diameter enlarges, and light wall cable sheath tube 2 termination outer wall fixed covers are chosen a place to give a banquet and overlapped 3, in the light wall cable sheath tube 2 termination insertion tube fittings 1, cover for seat 3 is clamped in pipe connecting piece 1 and enlarges in the gap of inwall behind the internal diameter and light wall cable sheath tube 2 outer walls; Cover for seat 3 one ends form retaining edge 31, the distance of retaining edge 31 from light wall cable sheath tube 2 terminations equals 1/2nd of pipe connecting piece 1 length, this retaining edge 31 is used to control the degree of depth (being the insertion depth mark) of light wall cable sheath tube 2 insertion tube fittings 1, retaining edge 31 is close to pipe connecting piece 1 port outer, the other end is provided with sealing ring 32, sealing ring 32 is clamped in pipe connecting piece 1 and enlarges in the gap of inwall behind the internal diameter and light wall cable sheath tube 2 outer walls, can play better sealing effectiveness.
The utility model can be applicable to the light wall cable sheath tube of single hole or porous.
Operating process of the present utility model is: 1.. cover for seat 3 respectively fixed cover be located at outer wall appropriate location, light wall cable sheath tube 2 two ends, the distance of retaining edge 31 from light wall cable sheath tube 2 terminations equals 1/2nd of pipe connecting piece 1 length, do like this is can be right after in pipe connecting piece 1 inwall for the inner tube head in two light wall cable sheath tubes 2 (at antipriming pipe), friction (single hole light wall cable sheath tube too) when the minimizing cable is managed in wearing, 2.. in light wall cable sheath tube 2 termination insertion tube fitting 1 one end openings, while cover for seat 3, sealing ring 32 enters in the gap that pipe connecting piece 1 enlarges inwall behind the internal diameter and light wall cable sheath tube 2 outer walls, press outer, pipe connecting piece 1 termination until retaining edge 31, this moment, a light wall cable sheath tube 2 was clamped in the pipe connecting piece 1,3.. another root one end has been fixed with in light wall cable sheath tube 2 insertion tube fittings 1 another opening of cover for seat 3, equally, cover for seat 3 is clamped in another root light wall cable sheath tube 2 in the pipe connecting piece 1, and two light wall cable sheath tube 2 terminations are right after, this has just finished the connection of two light wall cable sheath tubes 2, can find out this kind syndeton make every light wall cable sheath tube 2 and pipe connecting piece 1 to be connected sealing all fine, so the utility model can make the junction sealing of two smooth wall cable sheath tubes 2 fine; All the other many light wall cable sheath tubes 2 connect by that analogy, are not repeating here.Construction for convenience, above-mentioned 1., 2. step is finished in factory.Promptly in factory, each root light wall cable sheath tube 2 two ends appropriate location fixed cover cover 3 of choosing a place to give a banquet of going ahead of the rest, fixing sheathed pipe connecting piece 1 in termination therein again; Like this, when construction, only need do and once insert connection, can realize the connection of two light wall cable sheath tubes 2, simplify construction procedure, thereby reduced project cost.
In the utility model, pipe connecting piece 1 two ends can not enlarge internal diameter, in the light wall cable sheath tube 2 insertion tube fittings 1; equally; cover for seat 3 is in the gap of pipe connecting piece 1 inwall and light wall cable sheath tube 2 outer walls, and this and the utility model also are the claimed scope of the utility model for being equal to replacement.
