Abstract
The utility model relates to a rigid protection cable tube and solves a problem that cable is discarded because of surface scratch or even damage to the cable in a process of pulling the cable through a quite sharp multi-hole port of a communication cable tube in the prior art. The rigid protection cable tube comprises a tube body and further comprises a tube connector and a rigid protection sleeve, wherein an end portion of the tube body is mounted with the tube connector, through-holes are arranged between an outer wall and an inner wall of the tube connector along circumference, an inner wall of the through-hole is provided with a plurality of convex fins of flexible material, and the rigid protection sleeve is sleeved outside the tube connector. According to the rigid protection cable tube, the rigid protection sleeve is sleeved outside the tube connector, so rigidity of the tube body is effectively guaranteed; by changing an inner portion structure of the connector, the arc-shaped convex fins can support and separate the cable from the multi-hole port at an abutting portion of the cable tube, so surface scratch of the cable at the multi-hole port of the staggered abutting portion is avoided.
Description
Technical field
The utility model relates to the communications field, especially relates to a kind of rigid protection cable tube.
Background technology
The power cable pipe has another name called electric power comb, cement cable tube etc.The outstanding feature of power cable pipe is that intensity is high, frictional resistance is little, higher by 40% than common tube intensity, the anti-folding load 〉=12000N of body, external pressure load 〉=15000N, can be used for various other road pavements of level uses, the frictional resistance of inwall and cable is little to be the outstanding advantages of power cable pipe, and its coefficient of friction＜0.35 is starkly lower than other classification cable tubes such as fiberglass, PVC.Reduced the quantity of worker's well during logical cable, reduced project cost, increased cable pulling length.
Cable tube is antipriming pipe at present, having of square hole circular hole, when construction and installation, by the ring-type joint cable tube is docking together, cause easily like this porous joint dislocation of cable tube after the stack of the easy damage of the discontinuity of joint and alignment error and production error, and the porous port of cable tube is very sharp, easily the epidermis of cable is swiped when cable is dilatory in the hole, even the incised wound cable, cause cable to scrap.
Summary of the invention
The utility model technical issues that need to address are: in order to overcome the problem of above-mentioned middle existence, provide a kind of cable tube docking location place stressed evenly, not fragile and be not easy to hurt the rigid protection cable tube of cable.
The technical scheme that its technical problem that solves the utility model adopts is: this kind rigid protection cable tube comprises body, described cable tube also comprises pipe joint and rigid protection cover, on the end of body pipe joint is housed, offer through hole along circumference between the outer wall of pipe joint and the inwall, the inwall of through hole is provided with some the fins of being made by flexible material, and the outer cover of pipe joint is equipped with the rigid protection cover.
Further, described fin is to run through pipe joint; Body and pipe joint all are that modified polypropene is made, and the fin that flexible material is made is avoided the better effects if of scratch cable skin when installing cables.
The beneficial effects of the utility model are: the pipe joint outside is provided with the rigid protection cover, has effectively guaranteed the rigidity of body; By changing the joint internal structure, inwall at through hole is provided with fin, when the drag cable line, fin can be propped up the porous port that cable breaks away from cable body joint, avoided the porous port scraping cable skin of dislocation joint, even the incised wound cable, cause cable to scrap, greatly facilitate construction and installation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is rigid protection cable tube structural representation described in the utility model;
Fig. 2 is the generalized section of pipe joint part described in the utility model.
Accompanying drawing acceptance of the bid score state as follows: 1, body, 2, pipe joint, 3, the rigid protection cover, 2-1, through hole, 2-2, fin.
Embodiment
1 pair of the utility model is described in further detail by reference to the accompanying drawings now.This accompanying drawing is the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only shows the formation relevant with the utility model.
Rigid protection cable tube as shown in Figure 1 comprises body 1, described cable tube also comprises pipe joint 2 and rigid protection cover 3, pipe joint 2 is housed on the end of body 1, have through hole 2-1 along circumference between the outer wall of pipe joint 2 and the inwall, the inwall of through hole 2-1 is provided with some the fin 2-2 that made by flexible material, and the outer cover of pipe joint 2 is equipped with rigid protection cover 3.
Fin can be propped up the porous port that cable breaks away from cable body joint, has avoided the porous port scraping cable skin of dislocation joint, even the incised wound cable, causes cable to scrap.
Fin 2-2 runs through pipe joint 2, and body 1 and pipe joint 2 are modified polypropene and make.The fin of being made by flexible material is avoided the better effects if of scratch cable skin when installing cables, cheap for manufacturing cost.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
