Abstract
The utility model relates to a cable protection pipe and the connecting joint, the cable protection pipe comprises an outer pipe and a plurality of inner pipes, the outer pipe and the inner pipes or between the inner pipes are tangentally connected or connected by a reinforcement, the best shape of the outer pipe and the inner pipes is round; the connecting joint used for the cable protection pipe comprises a connection ring and a cone convex part which is bilaterally symmetrically connected with the connection ring, the cone convex part comprises a plurality of openings and inner chases which are adapted with the shape and the number of the inner pipes, the openings are ''V'' typed, the external diameter of the connection ring is adapted with the external diameter of the outer pipe. Using the structure, the increase of the outer pipe diameter can be maximum limited, and the increase of the cost of the utility model can be controlled, the using convenience of the utility model can also be improved, at the same time, the production convenience of the utility model can also be improved.
Description
Technical field:
The utility model relates to a kind of joint of protecting the protection tube of cable and being used for above-mentioned protection tube of being used to.
Background technology:
Carrying out cable laying when construction, need provide a protection tube to the cable of being laid usually, make cable directly not be subjected to the influence of extraneous poor environment and increase the service life.Other patent No. the inventor is in the patent application of ZL00259764.0; a kind of Cable protecting tube and jointing thereof are disclosed; described protection tube comprises outer tube and interior pipe; be connected and fixed by dowel between outer tube and the interior pipe and between the interior pipe, described jointing is the jointing that adapts with above-mentioned protection tube.The shortcoming of above-mentioned protection tube is; be connected and fixed by dowel between outer tube and the interior pipe and between the interior pipe; because described dowel need take the space in the outer tube; and the interior pipe sectional area on the whole that dowel connects is greater than the sectional area of singly depositing interior pipe integral body; therefore objectively increased the diameter of outer tube; this has not only caused increasing of protection tube cost, and has caused the inconvenience of construction.
Summary of the invention:
The purpose of this utility model is to provide that a kind of cost is lower, the Cable protecting tube of easy construction and jointing thereof.
For achieving the above object, the Cable protecting tube that the utility model provides, comprise outer tube and a plurality of in pipe, the tangent connection between described outer tube and the interior pipe and between the interior pipe.
Between described outer tube and the interior pipe and can also be connected by reinforcement between the interior pipe.
Described outer tube is circular.
Pipe is for circular in described.
More convenient for the utility model is used, pipe location recognition colour bar in the pipe position is provided with in described outer tube is corresponding.
For above-mentioned protection tube is reliably connected; the utility model also provides a kind of jointing of Cable protecting tube; it comprises connecting ring and the taper protuberance that joins with the connecting ring left-right symmetric; described taper protuberance comprises opening and the interior tube seat that adapts with interior tube shape, quantity, and described opening is " V " shape.
Above-mentioned protection tube is by the connection of jointing for convenience, and the external diameter of described connecting ring and the external diameter of outer tube adapt.
Because tangent connection the between the outer tube that comprises of the utility model and the interior pipe and between the interior pipe, perhaps between outer tube and the interior pipe and between the interior pipe except that tangent the connection, can also connect by reinforcement, like this, interior pipe sectional area on the whole can be controlled as far as possible for a short time, therefore can limit the increase of outer tube diameter to greatest extent, this not only can control increasing of protection tube cost, and the energy convenient construction; Pipe location recognition colour bar had also improved the convenience that the utility model uses in the pipe position was provided with in described outer tube is corresponding; Simultaneously, also can improve making convenience of the present utility model.
Description of drawings:
Fig. 1 is the Cable protecting tube structure chart that the utility model embodiment has three interior pipes;
Fig. 2 is the jointing structure chart of the Cable protecting tube of the utility model embodiment with three interior pipes;
Fig. 3 is the Cable protecting tube sectional view that the utility model embodiment has four interior pipes;
Fig. 4 is the Cable protecting tube sectional view that the utility model embodiment has seven interior pipes;
Fig. 5 is the Cable protecting tube sectional view that the utility model embodiment has reinforcement.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
At first with reference to figure 1, Fig. 3 and Fig. 4.Cable protecting tube described in the figure, comprise outer tube 1 and a plurality of in pipe 2, the tangent connection between described outer tube 1 and the interior pipe 2 and between the interior pipe 2.In other embodiment of the present utility model, between described outer tube 1 and the interior pipe 2 and can also be connected by reinforcement 7 between the interior pipe 2.That is to say, between outer tube 1 and the interior pipe 2 and can promptly can tangently be connected according to actual needs between the interior pipe 2, also can connect, with reference to figure 5 by reinforcement 7.Can make the utility model more can adapt to the needs of various applied environments like this.Be more convenient actual the use, can also outer tube is corresponding in, manage the position and manage location recognition colour bar 6 in being provided with.
The optimum shape of outer tube 1 of the present utility model and interior pipe 2 is circular, also can be other shape that needs, for example square in the reality certainly.
The jointing of the Cable protecting tube that the utility model provides is with reference to figure 2.It comprises connecting ring 3 and the taper protuberance 8 that joins with connecting ring 3 left-right symmetric; described taper protuberance 8 comprises and interior pipe 2 shapes; opening 5 that quantity adapts and interior tube seat 4; described opening 5 is " V " shape; simultaneously; the external diameter of the external diameter of described connecting ring 3 and outer tube 1 adapts; for making described jointing stable with being connected of described Cable protecting tube; on described taper protuberance 8, also have fit 10; with when the connection cable protection tube; match with the cooperation plush copper 9 of Cable protecting tube; this fit 10 is gradually dark to top orientation from the bottom, can make connection more convenient like this.Therefore, use this jointing to connect Cable protecting tube described in the utility model, and the fastness of increase connection and attractive in appearance.
