[0007] As a preferred light reducing joint with changeable direction, the number of the reverse hook steps is 4-5.
[0008] As a preferred light reducing joint with changeable direction, the bending part is a bending decoupling part with an angle of 15°-90°.
[0009] As a preferred light reducing joint with changeable direction, the diameter of the reverse hook step is smaller than that of the joint pipe body.
[0010] As a preferred light reducing joint with changeable direction, the outer thread is used to connect elbows, tees, mechanical tees and other pipe fittings.
[0011] As a preferred light reducing joint with changeable direction, the reverse hook step is used to connect a hose.
[0012] The outer thread and the barb step are machined by a thread rolling machine, and the joint pipe body is made of a British standard light steel pipe.
[0013] Compared with the prior art, the utility model has the advantages and positive effects that,
[0014] 1、 the utility model discloses a low -cost and can realize the reduced diameter product of directional connection function, joint pipe body adopts the light steel pipe of british standard, through thinning the wall thickness of joint pipe body, reduced product raw material cost, and reduced product single weight.
[0015] 2、 through using the barb step and outer thread of thread rolling machine, can improve the processing efficiency and reduce the single piece production cost, also improved processing efficiency.
[0016] 3、 through reducing the number of barb steps and shortening the blank length, reduce raw material consumption, reduce production cost.
[0017] 4、 through clamping the variable diameter portion, using cold bending process, the bending deformation is carried out to the bending part, meet the directional connection function, reduce the use of elbow fittings, also greatly reduce the production cost, satisfy market demand.
