Abstract

The utility model provides an assembled honeycomb-shaped optical cable sleeve-protective pipe, which is composed of an outer-layer pipe made from UPVC material, seven branch pipes, a connection supporting frame and two blocking pipes, wherein, positioning ribs are machined on the outer-wall surfaces of the outer-layer pipe and the blocking pipes. When the utility model is used for installing a cable communication line with the length of certain route, only a pipe connector provided with a positioning groove is adopted to be connected with a plurality of sleeve-protective pipes of the utility model orderly. The sleeve-protective pipe of the utility model can be installed and laid to reach the target for once without the need of being installed for twice, and has the advantages of labor saving, time saving, force saving, convenient operation and construction, installation-cost lowering and convenient maintenance.

Description

The cellular optical cable protecting casing of assembly type

The utility model relates to a kind of tubular article of producing with plastic material, is meant a kind of cellular optical cable protecting casing of assembly type with the UPVC material especially.

The protecting pipe that present domestic installing communication cable is used is a duplex sheath, and outer protective sleeve adopts PVC, cement, PE Ф 98 pipes, belongs to protective seam, destroys optical cable to prevent extraneous factor.Put on three HDPE Ф, 32 son pipes in the outer sheath tube pipe, optical cable is placed sub-pipe, HDPE Ф 32 sub-pipes are in order to prevent optical cable kink winding mutually therein, directly optical cable is not placed bassoon if there is the son pipe, in case find that wherein one has problem need pull out maintenance or when changing, just have any problem, therefore sub-pipe is absolutely necessary.Because Ф 98 pipes will be installed at twice with Ф 32 sub-pipes and lay, time-consuming, labour intensity is big, the cost height.

In order to overcome above-mentioned technology drawback, the purpose of this utility model, be provide a kind of need not to be divided into twice and as long as once just can install lay the saving of labor that puts in place, save time, the laborsaving and cellular optical cable protecting casing of lower-cost assembly type.

Solution of the present utility model is as follows.It has an outer tube that diameter is bigger, on the outer wall of outer tube, be processed with the positioning bar of arranging vertically that plays the location alignment effect, be provided with the cross section in outer tube inside and be cellular evenly distributed seven less root pipes of diameter, in outer tube between the outer wall of its inwall and seven root pipes, have quantity be at least one outer tube and seven root pipes are linked to each other be connected support, all offer the child pipe perforation that allows seven root pipes pass on each connection support, left side in outer tube, right two ends, have respectively between the outer wall of tight reeve outer tube inwall and seven root pipes, the pipe plug that outer tube is linked to each other with seven root pipes, all offer the child pipe perforation that allows seven root pipes pass on two pipe plugs, the outer end of two pipe plugs all has the pipe plug shirt rim of stretching out respectively outside the outer tube two pipe end faces, and the excircle wall equal diameters of the excircle wall diameter of pipe plug shirt rim and outer tube, the pipe plug positioning bar that the positioning bar on the outside wall surface that is provided with on the pipe plug shirt rim of two pipe plugs with outer tube aligns mutually.

The utility model with said structure has the long fiber optic communications circuit of certain distance when using being mounted to, and the pipe adapter that only needs to adopt the utility model optical cable protecting casing of many radicals amount and offer detent couples together to construct to lay and gets final product.Promptly be between every two adjacent basic utility model optical cable protecting casings, to adopt a pipe adapter, as long as in pipe adapter, coat PVC glue, detent on the pipe adapter is alignd with positioning bar on the outer tube (and pipe plug) of adjacent two basic utility model protecting pipes respectively, insert and get final product, just can accomplish to make seven root pipes in every adjacent two optical cable protecting casings concentric, once large and small pipe is laid and finish, it is very convenient to operate.For the ease of maintenance from now on, seven little sons are managed available different colours, are convenient to distinguish.

The utility model need not twice and puts in place as long as once just optical cable protecting casing is installed to lay, obviously accomplished the saving of labor, saved time, laborsaving, its operation construction is convenient, has reduced installation cost, and convenient later maintenance, have remarkable economic efficiency and social benefit.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the forward sectional structure chart of a kind of concrete structure of the utility model;

Fig. 2 is Fig. 1 side view of the present utility model;

Fig. 3 and Fig. 4 are respectively A-A and the B-B cut-open view of Fig. 1.

Referring to Fig. 1 to Fig. 4.The utility model optical cable protecting casing has an outer tube 1 that diameter is bigger, on the outer wall of outer tube 1, be processed with the positioning bar of arranging vertically 101 that plays the location alignment effect, be provided with the cross section in outer tube 1 inside and be cellular evenly distributed seven less root pipes 2 of diameter, in outer tube 1 between the outer wall of its inwall and seven root pipes 2, have two be separated by uniformly outer tube 1 is linked to each other with seven root pipes 2 be connected support 3, it is other quantity that the quantity of connection support 3 also can not be two, all offer the child pipe perforation that allows seven root pipes 2 pass on each connection support 3, left side in outer tube 1, right two ends, have respectively between the outer wall of tight reeve outer tube 1 inwall and seven root pipes 2, the pipe plug 4 that outer tube 1 is linked to each other with seven root pipes 2, all offer the child pipe perforation that allows seven root pipes 2 pass on two pipe plugs 4, the outer end of two pipe plugs 4 all has the pipe plug shirt rim 401 of stretching out respectively outside 1 liang of pipe end face of outer tube, and the excircle wall equal diameters of the diameter of the excircle wall of pipe plug shirt rim 401 and outer tube 1 is provided with the pipe plug positioning bar 402 that the positioning bar 101 on the outside wall surface with outer tube 1 aligns mutually on the pipe plug shirt rim 401 of two pipe plugs 4.Outer tube 1 of the present utility model, seven root pipes 2, connection support 3 and pipe plug 4 are all used UPVC (rigid polyvinyl chloride) made, connect support 3 respectively with outer tube 1 and seven root pipes 2 between be connected, and pipe plug 4 respectively with outer tube 1 and seven root pipes 2 between be connected, all adopt PVC glue to connect.
