Description

Technical Field

[0001] The utility model relates to a flexible joint for external threads of the same size. Background Art

[0002] Copper joints are used to connect pipes, equipment, bathroom fixtures, wires and cables, and other products. They are classified by function into reducers, sleeve joints, reducers, 90° elbows, 45° elbows, tees, reducing tees, crosses, reducing crosses, unions, flanges, pipe clamps, etc. The main materials are copper, brass, and bronze. According to their uses, they can be divided into water pipe joints, air conditioning pipe joints, refrigeration pipe joints, and equipment joints.

[0003] The male thread to union copper joints currently used in the market are all one size larger than the male thread. For example, if the male thread is G1", the union nut is G1-1 / 4". In some cases, the same size conversion is required, that is, G1" male thread to G1" union nut, which cannot be achieved with existing unions. Summary of the Invention

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a flexible joint for external threads of the same size, which can be quickly converted under the condition of the same size and has strong practicality.

[0005] In order to achieve the above purpose, the utility model is implemented as follows, which is a same-size external thread rotating joint, including

[0006] An external thread joint, comprising external threads, a central tube of the external thread joint, and an inwardly contracted step; the step is provided on one end of the central tube, and the external threads are provided on the other end of the central tube;

[0007] A flexible joint, comprising a slot, a flexible center tube and a nut. The slot is arranged in one end of the flexible center tube, and the slot can cooperate with the step so that the flexible joint is arranged on the external thread joint. The nut is arranged on the other end of the flexible center tube, and an internal thread is provided in the nut, and the diameter of the internal thread is consistent with the diameter of the external thread.

[0008] In this technical solution, a step external thread is provided on the outer edge of the step, and a slot internal thread is provided on the inner edge of the slot, and the step external thread and the slot internal thread can be threadedly fitted and fixed.

[0009] In this embodiment, the nut is a hexagonal nut.

[0010] In this embodiment, the outer middle section of the central tube of the male connector is a regular hexagon.

[0011] In this embodiment, the external thread connector is integrally formed.

[0012] Compared with the prior art, the utility model has the advantages that, under the condition of the same size, the conversion can be performed quickly and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS
