Abstract
The utility model discloses a threading sheath for cable tube, which comprises a equal part and an expansion part, wherein the expansion part locates in one end of the equal part and integrates with the equal part as a whole. Insert the equal part of the threading sheath provided in the utility model into the cable tube, and form the expansion part as a bell mouth on threading tube mouth of the cable tube. When a electric wire and cable passes through the cable tube, contact between the electric wire and cable and the cable tube inserting mouth, hence insulation sheath of the electric wire and cable can avoid scuffing by bur of cable tube mouth.
Description
Technical field
The utility model relates to a kind of electric wire threading protective device, particularly, relates to a kind of being used for when electric wire penetrates cable tube, the threading sheath that the electric wire that protection is passed through is not damaged by the burr of cable tube termination.
Background technology
On engineering, all be that the cable tube end machining that will wear electric wire is become toroidal during most of electric wire poling at present, its objective is to prevent that its insulation sheath is scratched by the burr of the cable tube mouth of pipe when electric wire passes cable tube.Though such processing can be played certain protective role; but the marquis still scratches the electric wire crust when a lot; reason is the horn mouth processing on demand at the scene often of the threading end of cable tube; generally pound and form with the roasting hammer of gas welding; so horn mouth surface irregularity; a lot of electric wires are still scratched insulation sheath when poling, thereby cause economic loss, or bring potential safety hazard.
The utility model content
Because the above-mentioned defective of prior art, the purpose of this utility model is to provide a kind of device that this cable tube mouth of pipe damages of avoiding can protect electric wire to pass cable tube the time.
The utility model provides a kind of threading sheath that is used for cable tube, and described threading sheath comprises isometrical and wide diameter portion, and this wide diameter portion is positioned at an end of isometrical portion and is connected as a single entity with isometrical portion.
In embodiment of the present utility model, the external diameter of described isometrical portion is equal to or slightly less than the internal diameter of described cable tube, so that isometrical can be inserted cable tube by an end of its relative wide diameter portion.
In a preferred embodiment of the present utility model, described threading sheath has at its vertical upwardly extending entire body groove, is used for electric wire is moved into or shift out the threading sheath.
In another preferred embodiment of the present utility model, the wall of wide diameter portion bends outwards camber on the hole enlargement direction.
Isometrical with threading sheath of the present utility model is inserted cable tube, and wide diameter portion is positioned at cable tube threading mouth of pipe place, so when electric wire etc. is penetrated cable tube, can avoid contacting of electric wire and the cable tube mouth of pipe, thereby can avoid the insulation sheath of electric wire to be scratched by the burr of the cable tube mouth of pipe.The cable tube two ends needn't be processed into broadening formation in the scene.
Be described further below with reference to the technique effect of accompanying drawing, to understand the utility model fully design of the present utility model, concrete structure and generation.
Description of drawings
Fig. 1 is the front elevational schematic of a specific embodiment of threading sheath of the present utility model;
Fig. 2 is the front elevational schematic of the another specific embodiment of threading sheath of the present utility model;
Fig. 3 is the schematic perspective view that has the threading sheath of groove of the present utility model.
Embodiment
Fig. 1 is the schematic diagram of threading sheath 1 of the present utility model, is made of isodiametric tubular short tube 2 and the wide diameter portion 3 that is bell mouth shape.Wherein isometrical pipe 2 is repressed by metal sheet or thin metallic tubd with wide diameter portion 3, the method for welding and so on forms integral body.Usually, sheath is made by iron pipe or copper pipe.
The external diameter of isometrical pipe 2 is equal to or slightly less than the internal diameter of corresponding cable tube (being the electric wire pillar), so that isometrical pipe 2 can insert from the cable tube mouth of pipe just, and wide diameter portion 3 is bell mouth shape and is positioned at the cable tube end because external diameter can't enter cable tube greater than cable tube.
Like this, electric wire cable tube two ends needn't be made toroidal on the engineering, as long as insert threading sheath 1 of the present utility model at the cable tube two ends, just can avoid that the external insulation skin is damaged when the electric wire poling.
Usually, the thickness of threading sheath can be made the series of 0.3mm～4mm different wall according to the difference of cable tube series, and the length of cable tube sheath is also directly made the different series of 30mm～300mm through series according to iron pipe.When construction,, freely select different threading sheaths according to electric wire pillar thickness difference.
In the present embodiment, as shown in Figure 1, wide diameter portion 2 is linear reducing on the hole enlargement direction.But, mode as an alternative, as shown in Figure 2, at hole enlargement direction (among the figure for vertically to), the wall portion of wide diameter portion 2 is the arc that bends outwards.
As shown in Figure 3, have at its vertical upwardly extending entire body groove 4, be used for electric wire is moved into or shift out the threading sheath at threading sheath of the present utility model.
Vertically the entire body groove solves the online electric wire of wearing and uses, because the entire body groove can insert sheath in original electric wire pillar being through originally after electric wire in the electric wire pillar moves into sheath earlier by groove again.Do not have electric wire in the electric wire pillar when groove is also newly constructed, get final product so sheath just can directly insert in the electric wire pillar.
Threading sheath of the present utility model can be used for holding wire poling, low-voltage power electric wire poling, high-tension cable poling and various electric screen cabinets etc.
Those of ordinary skill can be understood in the art; object lesson described in this specification is a preferred embodiment of the present utility model; all change or modifications of making according to design of the present utility model all should be in claim protection range of the present utility model.
