Abstract

The utility model relates to a wire tubular combined elbow, which comprises an elbow body 1. The utility model is characterized in that the elbow body 1 is formed by splicing two semi-circular arc-shaped blocks 3 which are in an angle with more than 45 DEG, the side edges of the semi-circular arc-shaped blocks 3 are respectively provided with splicing ribs 2, and the upper sides of the splicing ribs 2 are provided with a convex nail 4 and a hole 5 which are matched and fixed mutually. The construction which uses the combined elbow for laying a wire casing tube is labor saving and time saving, and a wire insulation layer and a wire core have no damage.

Description

The cable conduct combined elbow

The utility model relates to the equipment that a kind of laying wires is used, especially a kind of cable conduct combined elbow.

At present, the cable conduct elbow of selling on the market is an integral body, in the construction of laying wires sleeve pipe, poling successively, wear elbow, poling again, wear elbow again ... what have bend to wear the how many times pipe successively, elbow, and when running through each elbow, all must (it be also passable to wear big elbow with little line certainly with just passing after the electric wire bending, but the material of waste is too many), and need when wearing straight tube whole section electric wire straightening not only required great effort but also time-consuming, inefficiency, and during misoperation, the phenomenon that electric wire insulation layer is scratched happens occasionally, even the fault of the core that occurs fractureing.

The purpose of this utility model is to provide a kind of laborsaving in the construction of laying wires sleeve pipe, saving of labor, saves time, and does not damage the cable conduct combined elbow of electric wire insulation layer and core.

The purpose of this utility model is to realize like this, this cable conduct combined elbow comprises the elbow body, be characterized in that the elbow body is 45 degree by two and forms with the semicircular arc piece of upper angle, is provided with in the junction of semicircular arc piece and coincide mutually and stationary device.

Because adopt above structure, the utility model cable conduct combined elbow replaces former one piece elbow by two semicircular arc amalgamation pieces, in the construction of laying-out, after only straight tube need being packaged, the combined elbow that closes at each turning gets final product.Use this elbow saving of labor, laborsaving, save time, quick and easy, and do not damage electric wire insulation layer and core.Producer only need change a mould and need not increase any equipment and can produce, and has very strong practical reference value.

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

Fig. 1 is a cable conduct combined elbow perspective view.

Fig. 2 is for forming the semicircular arc piece schematic diagram of this elbow.

As shown in Figure 1 and Figure 2, this cable conduct combined elbow body 1 can adopt PAC fire proofing (plastics) to make.Elbow body 1 is 45 degree by two and forms (being put together) with the semicircular arc piece 3 of upper angle (being generally 90 degree), the radius at its arc piece 3 two ends is greater than the radius at arc piece 3 middle parts, after promptly two arc pieces piece together elbow 1, the middle part of elbow 1 is identical with the caliber of same specification, the two ends of elbow 1 then are a bit larger tham the caliber of same specification, are beneficial to be enclosed within outside the termination of two straight tubes.Be provided with the also stationary device that coincide mutually in the junction of semicircular arc piece 3, its concrete structure can adopt following several: be respectively equipped with an amalgamation muscle 2 at two edges of every semicircular arc piece 3, be provided with on amalgamation muscle 2 and coincide mutually and fixing protruding nail 4 and through hole 5; Perhaps amalgamation muscle 2 is provided with the through hole (being through hole on the two amalgamation muscle) that tapping screw is used is installed, with screw two arc pieces are tightened together (generally adopting on the bigger elbow of caliber, not shown); Perhaps on the position of amalgamation muscle, establish box and pin muscle seam (not shown), also can adopt bonding agent that the two halves circular arc-like block is bonded together.Amalgamation muscle 2 or button muscle seam and semicircular arc piece 1 are Integratively formed.The angle of semicircular arc piece 1 is generally 90 degree, and symmetries such as the amalgamation muscle at two ends and protruding nail 4, hole 5, so, only need a mould to make and coincide mutually and two fixing circular arc-like blocks 1.

Claims

1, a kind of cable conduct combined elbow comprises elbow body (1), it is characterized in that, elbow body (1) is 45 degree by two and forms with the semicircular arc piece (3) of upper angle, is provided with in the junction of semicircular arc piece (3) and coincide mutually and stationary device.

2, cable conduct combined elbow according to claim 1, it is characterized in that, identical and the fixture of described semicircular arc piece (3) is meant at the edge of semicircular arc piece (3) and is respectively equipped with amalgamation muscle (2) that amalgamation muscle (2) is provided with the hole that identical and fixing mutually protruding nail (4) and hole (5) or installation tapping screw are used.
