Description
Technical field
The utility model is related to a kind of prefabricated active wells of variable drive connector, relate generally to cable work well field.
Background technology
Cable is generally laid in the cable duct of underground.Because every disk cable only has certain length, about hundreds of meters, in order to lay
Longer cable run, it is necessary to multistage cable connect, making and place cable connector needs certain space, this space is known as electricity
Cable work well（Electric well）, general width and depth are both greater than cable duct, have cover board on ground.The requirement of work well ensures its seal, prevents
Water insect prevention.And electric well with extraneous contact site in addition to well lid well head is exactly the import and export of cable, at cable incoming-outgoing mouth usually very
Difficulty is really achieved sealing, because the cable incoming-outgoing mouth of electric well is molding when being electric well construction, once it is molded its disengaging
Mouth diameter can not just be changed, if replacing the cable of other diameters, be difficult to reach sealing again.
Utility model content
For more than the deficiencies in the prior art, the utility model proposes a kind of prefabricated active wells of variable drive connector.
In order to achieve the above objectives, the technical solution of the utility model is：Including prefabricated profiled cable, cable side wall is equipped with
Cable aperture, the side wall of cable aperture is fixed with reducing cylinder, mounting flange is fixed in one end port of reducing cylinder, another in reducing cylinder
One end, which is equipped with, slides flange, and mounting flange and the reducing cylinder slided between flange are interior equipped with expansion loop, expansion loop axial direction correspondent method
Blue through-hole is equipped with squeezing through-hole, has mounting flange, slip flange and expansion loop in extruding bolt-through and is locked in three
Together.
The technical principle of the utility model has the beneficial effect that：Using this programme, cable is placed in reducing cylinder, then
Rotary squeezing bolt reduces the spacing for sliding flange and mounting flange, and then extrusion expansion body, and the expander being squeezed will
Inwardly expansion, the diameter of cable aperture will reduce, and then cable seal is fixed in cable aperture, therefore the diameter of fixed cable
Diameter without the cable aperture for being confined to set in advance can reduce cable bore dia in the later stage.
Further, expansion loop madial wall be equipped with several lamellasomes, the sheet body be strippable elastic strip body, each lamellasome
Length be less than this layer circumference, convenient for by lamella change cable aperture diameter, increase reduce lamella can change electricity
The diameter in cable hole.
Further, each lamellasome is made of two small lamellas, convenient for lamella when being squeezed by expander, is shunk
Change shape.
Further, the width of lamella is less than the width of expander, and width can narrow when expander expands, narrower width
Lamella will not interfere the deformation of expander.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Attached drawing is briefly described needed in description, it should be apparent that, the accompanying drawings in the following description is only that this practicality is new
Wherein two width of type, for those of ordinary skill in the art, without having to pay creative labor, can be with root
Other attached drawings are obtained according to these attached drawings.
Fig. 1 is the structure diagram of the utility model embodiment；
Fig. 2 is the partial enlarged view of A in Fig. 1.
Wherein, 1- works well, 2- cables, 3- cable mounting holes, 301- reducing cylinders, 302- extruding bolts, 303- expanders,
304- slides flange, 305- lamellas.
Specific embodiment
Below in conjunction with attached drawing, the technical solution in the utility model is clearly and completely described, it is clear that retouched
The embodiment stated is only the preferred embodiment of the utility model, instead of all the embodiments.Based in the utility model
Embodiment, those of ordinary skill in the art's all other embodiments obtained without making creative work, all
Belong to the range of the utility model protection.
Embodiment
As shown in Figure 1, including prefabricated profiled cable, cable side wall is equipped with cable aperture, and the side wall of cable aperture is fixed with change
Diameter cylinder is fixed with mounting flange in one end port of reducing cylinder, is equipped in the reducing cylinder other end and slides flange, mounting flange and
It slides and expansion loop is equipped in the reducing cylinder between flange, the through-hole of expansion loop axial direction companion flange is equipped with squeezing through-hole, is squeezing
Bolt-through has mounting flange, slides flange and expansion loop and lock together three, if expansion loop madial wall is equipped with dried layer
Sheet body, the sheet body are strippable elastic strip body, and the length of each lamellasome is less than the circumference of this layer, and each lamellasome is by two
A small lamella composition, the width of lamella are less than the width of expander.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
