Utility model content
The problems referred to above that exist for prior art, the utility model provides a kind of PVC double-wall corrugated pipe.
To achieve these goals, the utility model adopts following technical scheme: a kind of PVC double-wall corrugated pipe, comprise body, and described inboard wall of tube body top arranges groove along its length, on described groove, thread guide devices is set, and this device has:
Pedestal, it is arranged in described groove;
Screw mandrel, it is arranged on described pedestal below, and described screw mandrel front end or rear end are provided for the operating parts of rotary screw;
Slide block, it is arranged on described screw mandrel, and is connected with described pedestal;
Cover line mechanism, it is arranged on the below of described slide block and is connected with it, described cover line mechanism has the collar, left side or right side at the described collar arrange the through hole with negative thread, in described through hole, adjusting bolt are set, and described adjusting bolt deviates from one end of head along horizontally set regulating spring, described regulating spring one end be that adjusting bolt is connected, the other end with for pushing against the laminate of cable, be connected, after rotating operation part, slide block drives cover line mechanism to seesaw on screw mandrel.
Further, the end face of described laminate is cambered surface.
Further, described operating body is discoid pieces or " L " type rod member.
Further, described pedestal is arranged in described groove by fastening structure is detachable, and described fastening structure has the first fastening structure and the second fastening structure, and they are arranged symmetrically in front end or the rear end of described groove, and described the first fastening structure has:
Clamp, its two groove shoulders that are separately positioned on groove front end are upper, and one end of described clamp and described groove shoulder are hinged, and the other end extends to the lower surface of described pedestal;
Some stage clips, it is longitudinally arranged between the bottom surface of described groove front end and the upper surface of described pedestal.
Compared to existing technology, the utlity model has following advantage: the operation of the utility model threading is convenient, and efficiency is higher.
Accompanying drawing explanation
Fig. 1 is the double-wall corrugated partial structurtes schematic diagram of PVC in embodiment, this front end that is body, simultaneously not shown ripple struction.

In figure, 1-body, 2-pedestal, 3-screw mandrel, 4-slide block, 5-clamp, 6-stage clip, the 71-collar, 72-adjusting bolt, 73-regulating spring, 74-laminate.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Embodiment: as shown in Fig. 1 to 4, PVC double-wall corrugated pipe comprises body, and body cross section is circular, its inside is accommodation space, for wiring, inboard wall of tube body top arranges groove along its length, and thread guide devices is set on groove.
Thread guide devices, for clamping the termination of cable, is then delivered to the other end of body from body one end by thread guide devices.
Thread guide devices has pedestal, screw mandrel, slide block and cover line mechanism.Pedestal is arranged in described groove, screw mandrel is arranged on described pedestal below, described screw mandrel front end or rear end are provided for the operating parts of rotary screw, slide block is arranged on described screw mandrel, and be connected (particularly with pedestal, slide block is connected with the guide rail on pedestal), cover line mechanism is arranged on the below of slide block and is connected with it, cover line mechanism has the collar, left side or right side at the collar arrange the through hole with negative thread, adjusting bolt is set in through hole, adjusting bolt deviates from one end of head along horizontally set regulating spring, regulating spring one end be that adjusting bolt is connected, the other end with for pushing against the laminate of cable, be connected, after rotating operation part, slide block drives cover line mechanism to seesaw on screw mandrel.
Cable is through in the collar, then by adjusting bolt, compress, cable after fastening is under the drive of slide block, from one end of body, be transported to the other end of body, the motion of sliding realizes by operating operation part, when workman rotates in a circumferential direction after operating parts, drive screw mandrel rotation, therefore can realizing, slide block moves forward and backward.Slide block and screw mandrel relative motion are to adopt lead screw transmission mode of the prior art (lead screw pair).
The end face of described laminate is cambered surface, and because cable cross section is circular, therefore in pushing against the process of cable, laminate has changed face contact to the contact of cable into by traditional some contact, cable is more difficult loosening, simultaneously in the process pushing against, and not fragile cable.
As shown in Figure 5 or Figure 6, operating body is discoid pieces or " L " type rod member.
Especially, pedestal is arranged in described groove by fastening structure is detachable, described fastening structure has the first fastening structure and the second fastening structure, they are arranged symmetrically in front end or the rear end of described groove, the first fastening structure has clamp and some stage clips, clamp is separately positioned on two groove shoulders of groove front end, one end of clamp and described groove shoulder are hinged, the other end extends to the lower surface of described pedestal, and stage clip is longitudinally arranged between the bottom surface of described groove front end and the upper surface of described pedestal.
The first fastening structure that is positioned at front end of take is example, when needs are dismantled pedestal, clamp is pulled forward, and clamp is supporting base no longer just, and now pedestal front end is in removable state.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
