Description

A kind of big radian elbow

[technical field]

The utility model relates to the technical field of electrical casing pipe, especially a kind of technical field of big radian elbow.

[background technique]

In most house decoration, people realize wiring to circuit in such a way that conducting wire passes through casing, and due to The layout structures such as house and furniture, conducting wire usually need to turn or be bent.Traditional way is to be curved tubing with spring to need The angle wanted reuses straight-through pipe fitting and is attached to tubing, although this way can solve casing turn problems, still, Since casing is generally hard vertical bar shape product, the casing after being bent using spring, which can generate, to whiten and buckling phenomena, not only shadow The effect of threading is rung, casing quality is had a greatly reduced quality, and unsightly, especially to the non-white casing in fine fitment.The patent No. 201621091025.8 disclose a kind of big radian elbow of integrated injection molding, although solve makes casing whiten pleat using spring bending The problem of wrinkle, but bending angle is limited, and production is relative complex, is easy to appear defect at bellmouth and elbow body transition.

[utility model content]

The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of big radian elbow, overall structure Simply, mating install convenient, it is low in cost, it is convenient for production.

To achieve the above object, the utility model proposes a kind of big radian elbow, including elbow main body and bell and spigot, institutes Stating elbow main body is the bend pipe that one section of radian is 30~90 °, and the bell and spigot is two sections and is located at the straight of elbow main body both ends Pipe, the elbow main body are connected with the outer wall of bell and spigot by arc-shaped transition, and the inner wall of the bell and spigot is equipped with socket joint step.

Preferably, the elbow main body and bell and spigot are the integral structure of fire-retardant material single injection-molded.

Preferably, the elbow main body is the curved bend pipe of plane.

Preferably, the radian of the elbow main body is 45 °.

Preferably, the elbow main body is identical with the outer diameter of bell and spigot.

Preferably, the socket joint step is located at the junction of bell and spigot and elbow main body.

The utility model has the beneficial effects that the utility model uses integrated injection molding, simple production process, product defects Few, appearance is smoothly beautiful, efficiently solves product stress whitening caused by bend pipe；Big radian elbow and casing are used cooperatively, with When casing connection, casing is inserted into bell and spigot, is terminated in socket joint step, can accurately be calculated the insertion of casing.

The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.

[specific embodiment]

Refering to fig. 1 to Fig. 4, a kind of big radian elbow of the utility model, including elbow main body 1 and bell and spigot 3, the elbow Main body 1 is the bend pipe that one section of radian is 30~90 °, and the bell and spigot 3 is two sections of straight tubes for being located at 1 both ends of elbow main body, The elbow main body 1 is connected with the outer wall of bell and spigot 3 by arc-shaped transition, and the inner wall of the bell and spigot 3 is equipped with socket joint step 2, the elbow main body 1 and bell and spigot 3 are the integral structure of fire-retardant material single injection-molded, and the elbow main body 1 is plane The curved bend pipe of type, the radian of the elbow main body 1 are 45 °, and the elbow main body 1 is identical with the outer diameter of bell and spigot 3, described to hold Slotting platform rank 2 is located at the junction of bell and spigot 3 and elbow main body 1.

Utility model works process:

A kind of big radian elbow of the utility model during the work time, is used cooperatively with casing, when with casing connection, casing It is inserted into bell and spigot 3, terminates in socket joint step 2, complete connection work.Multiple big radian elbows can pass through the close connection group of casing It closes, realizes monoplane or the bending of multilevel multi-angle.Bell and spigot 3 and elbow main body 1 are fire-retardant material, play fire-retardant work With caning effectively protect conducting wire.

Above-described embodiment is the explanation to the utility model, is not the restriction to the utility model, and any pair of sheet is practical new Scheme after type simple transformation belongs to the protection scope of the utility model.
