Abstract
The utility model provides a cable lead-down tube rainproof casing tube which comprises a rainproof casing tube body which is sleeved outside a cable lead-down tube. The rainproof casing tube body is formed by the combination of two oppositely opened semi-tube bodies. One side of each of the two semi-tube bodies is connected through a hinge shaft, and the other side of each of the semi-tube bodies is provided with a concave and convex fitting edge. The two semi-tube bodies are embedded to form the tubular rainproof casing tube through the concave and convex fitting edges. According to the cable lead-down tube rainproof casing tube, two composable semi-tube bodies are embedded to form the cable lead-down tube rainproof casing tube with easy disassembly and assembly through the hinge shafts and the concave and convex fitting edges, a cable and a lead-down tube can be closely attached and fixed, and a good sealing effect can be achieved. The cable lead-down tube rainproof casing tube can be used for a long time, a phenomenon of loose sealing of a tube mouth can be avoided, the structure is simple, and the cable lead-down tube rainproof casing tube is convenient to install.
Description
Technical field
The utility model relates to a kind of cable rain insensitive device, is specially a kind of optical cable that is applied to fiber cable joint place and draws the rainproof sleeve pipe of lower pipe.
Background technology
In prior art, to draw the rainproof measure in lower pipe place be to adopt anti-chamotte or insulating tape to be wound around to carry out mouth of pipe shutoff to optical cable, and plugging effect is not good, grown that anti-chamotte is dry and cracked, insulating tape lost efficacy the time, and the mouth of pipe has gap, does not reach the object of shutoff.Also have and adopt plastic foil winding method to carry out rainproof protection, although these measures are simple, the standard not that operates all, can leave potential safety hazard.In prior art, have opposite opened rain-proof safety cap, wherein two opposite opened rainhats are connected by bolt, and centre clamps sealing gasket.Because bolt easy-to-rust causes rainhat loosening, rainproof function is lost, and in addition, due to bolts, assembly and disassembly are all inconvenient, when particularly the serious corrosion of bolts and nuts is integrated, are difficult to dismantle.
Summary of the invention
The disadvantage of bringing in order to overcome existing shutoff mode, the utility model provides a kind of optical cable to draw the rainproof sleeve pipe of lower pipe, has solved mouth of pipe shutoff not tight, operates nonstandard problem.
A kind of optical cable draws the rainproof sleeve pipe of lower pipe, comprise and be socketed in the rain-proof cover tube body that optical cable draws lower pipe outside, described rain-proof cover tube body is to be combined by two semicanal bodys splitting, it is characterized in that a side of two semicanal bodys is by stud connection, the opposite side of two semicanal bodys has concavo-convex chimeric limit, described concavo-convex chimeric limit, two semicanal body interlockings is consisted of to the rainproof sleeve pipe of tubulose.
Described optical cable draws the rainproof sleeve pipe of lower pipe, it is characterized in that described rainproof sleeve pipe body consists of two sections of different bore sleeve combination, wherein body bore in top is less than bottom body bore, in two ends mouth of pipe inner side, is respectively arranged with upper orifice O-ring seal and lower nozzle O-ring seal.
Optical cable of the present utility model draws the rainproof sleeve pipe of lower pipe, adopt hinge and concavo-convex chimeric limit that two semicanal bodys capable of being combined are formed to an optical cable that is easy to installation and removal and draw the rainproof sleeve pipe of lower pipe, it can fit tightly optical cable and draws lower pipe and fixed, and can reach good plugging effect., can there is not the not tight phenomenon of mouth of pipe shutoff in long-term use, simple in structure, easy for installation.
Accompanying drawing explanation
Fig. 1 is that two semicanal bodys are by stud connection structural representation;
Fig. 2 is another embodiment structural representation of the present utility model.
In figure, 1-hinge, 2-upper orifice O-ring seal, the chimeric limit of 3-, 4-body, 5-lower nozzle O-ring seal.
Embodiment
Shown in Fig. 1, optical cable of the present utility model draws the rainproof sleeve pipe of lower pipe and is combined by two semicanal bodys, a side at two and half bodys has hinge arrangement, by hinge 1, connect, the opposite side of two semicanal bodys is shaped with the chimeric limit 3 of recessed/male structure, by described chimeric limit, two semicanal bodys 4 can be combined as to rain-proof cover tube body.In order to adapt to optical cable, draw the upper and lower bore difference in lower pipe jointing part position, the caliber of described rain-proof cover tube body is designed to the large structure of the little bottom of top caliber caliber, and in upper lower nozzle inner side, fix an O-ring seal, i.e. upper orifice O-ring seal 2 and lower nozzle O-ring seal 5 respectively.In use, no matter how put upper and lower mouth of pipe position, all can not intake by the mouth of pipe.During use, rain-proof cover pipe box is connected on to installation site, with the hand-tight button one chimeric limit of side, can make two and half bodys be integrated is rain-proof cover tube body.
Claims (2)
1. an optical cable draws the rainproof sleeve pipe of lower pipe, comprise and be socketed in the rain-proof cover tube body that optical cable draws lower pipe outside, described rain-proof cover tube body is to be combined by two semicanal bodys (4) of splitting, a side that it is characterized in that two semicanal bodys is connected by hinge (1), the opposite side of two semicanal bodys has concavo-convex chimeric limit (3), described concavo-convex chimeric limit, two semicanal body interlockings is consisted of to the rainproof sleeve pipe of tubulose.
2. optical cable according to claim 1 draws the rainproof sleeve pipe of lower pipe, it is characterized in that described rainproof sleeve pipe body consists of two sections of different bore sleeve combination, wherein body bore in top is less than bottom body bore, in two ends mouth of pipe inner side, is respectively arranged with upper orifice O-ring seal (2) and lower nozzle O-ring seal (5).
