Abstract
The utility model relates to a bending pipe joint for electric appliances, which is used in the vertical laying of a metal electric guide pipe in the construction engineering. The utility model comprises a bending guide pipe of 90 DEG and a straight guide pipe, wherein the straight guide pipe is rolled with an arc groove along the periphery of a circle and the distance from the arc groove to the combining part of the straight guide pipe and the bending guide pipe is more than 10 millimeters. Accordingly, the straight guide pipe and the bending guide pipe of the bending pipe joint have high precision on shapes and positions, and an inserting opening also has high dimensional precision; the fit precision of the bending pipe joint and the guide pipes is improved, and the verticality and the planeness of the laying of the guide pipes are ensured.
Description
It is a kind of electric union elbow that the utility model relates to, and it is metal electric conduit employed a kind of joint when vertical direction is laid in architectural engineering.
What use in the architectural engineering at present is common electrical airway union elbow, and the course of processing of this union elbow is, at first precalculated position, straight catheter two ends is rolled into groove along excircle, and this position is straight length and position, bend loss boundary.And then it is curved 90 ° bend pipe.The variation of the groove of this moulding union elbow is bigger, can't guarantee that the conduit morpheme and the dimensional accuracy of being scheduled to, union elbow are difficult to guarantee the perpendicularity and the flatness of its quality of fit and catheter laying when inserting mouthful conduit.
The purpose of this utility model provides a kind of electric union elbow, overcomes above-mentioned defective, guarantees the accuracy of form and position and the dimensional accuracy of catheter fabrication, improves the quality of fit of union elbow and conduit, guarantees the perpendicularity and the flatness of catheter laying.
The purpose of this utility model is to realize like this; A kind of electric union elbow, comprise 90 ° of curved conductors and straight catheter, respectively be extended with a straight catheter along tubular axis to direction at 90 ° of curved conductor two ends, it is characterized in that one circle periphery is rolled into arcuate furrow in straight catheter section upper edge, the distance at the position, boundary of the position of arcuate furrow and straight catheter and curved conductor is greater than 10 millimeters.
Accompanying drawing is a structural representation of the present utility model.
Wherein
1,90 ° of curved conductors, 2, straight catheter, 3, arcuate furrow,
4, the position, boundary of expression straight catheter 2 and curved conductor 1,
L represents the distance at the position, boundary of arcuate furrow 3 and straight length 2 and bend loss 1.
As shown in the figure, this electric union elbow comprises that one curved has 90 ° of curved conductors 1, tubular axis along curved conductor 1 respectively is extended with a straight catheter 2 to direction, one circle periphery is rolled into arcuate furrow 3 in straight catheter section 2 upper edges, and distance L is greater than 10 millimeters between the position, boundary 4 of the position of arcuate furrow 3 and straight catheter 2 and curved conductor 1.
The course of processing of this union elbow has been rolled arcuate furrow 3 with the precalculated position at straight catheter two ends along excircle earlier, and the degree of depth of its groove is 2 millimeter, its straight catheter is curved 90 degree again.At last pipe end is carried out shaping, reach the predetermined accuracy of form and position and dimensional accuracy.This precalculated position is to determine by the caliber of different conduits.The caliber of the electric conduit that uses is respectively 16,20,25,32,40,50 millimeters at present, adopts four times (calibers) curved or six times (caliber) curved size that calculates straight length and position, bend loss boundary 4 usually.Usually selecting arcuate furrow 3 for use is the 10-80 millimeter apart from the distance L at the position, boundary of straight length 2 and bend loss 1, and such union elbow is in the course of processing of carrying out crooked 90 degree, and arcuate furrow can not produce any distortion, guarantees the accuracy of form and position that it is higher.
The utility model has the advantages that straight catheter and the curved conductor of such union elbow have The high accuracy of form and position, interface also have higher dimensional accuracy, have improved union elbow and conduit Quality of fit, guarantee perpendicularity and the flatness of catheter laying.
Claims (2)
1, a kind of electric union elbow, include 90 ° of curved conductors (1) and straight catheter (2), respectively be extended with a straight catheter (2) along tubular axis to direction at 90 ° of curved conductors (1) two ends, it is characterized in that being rolled into arcuate furrow (3) in straight catheter (2) section upper edge one circle periphery, the distance L at the position, boundary (4) of the position of arcuate furrow and straight catheter and curved conductor is greater than 10 millimeters.
2, electric union elbow according to claim 1 is characterized in that arcuate furrow (3) is the 10-80 millimeter apart from the distance L at the position, boundary of straight length (2) and bend loss (1).
