[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] For reference Figure 1-2 The utility model is described as follows:

[0017] Embodiment 1: An adjustable double-head pipe connector includes two rotating heads, each of which is a hemispherical structure having a circular plane and a curved surface. The hemispherical design allows the rotating head to be more flexible when rotating, reducing resistance and friction during the rotation process.

[0018] An axial hole 2 is provided at the center of the rotating head and passes through both sides thereof. The axial hole 2 is arranged perpendicular to the plane on the rotating head, thereby providing an accurate rotation axis for the relative rotation of the two rotating heads.

[0019] A connector 3 is provided on the radial side of the circular plane of the rotating head. The connector 3 is used to connect with the tubular parts. The connector 3 located on the radial side of the circular plane of the rotating head is convenient for connection with the tubular parts. The setting of its position and direction is conducive to the layout and installation of the pipe fittings.

[0020] The two rotating heads are combined to form a spherical structure and a rotating connection is formed. The shaft hole 2 is connected with a pin 4, which realizes all-round angle adjustment and can meet complex pipeline connection requirements.

[0021] The two rotating heads are rotating head 11 and rotating head 2 12. One end of the pin 4 is threadedly connected to the shaft hole 2 on the rotating head 11. The other end of the pin 4 is provided with a nail cap 5. The diameter of the nail cap 5 is larger than the diameter of the shaft hole 2. The rotating head 2 12 is located between the nail cap 5 and the rotating head 11, which is equivalent to that the rotating head 11 is fixedly connected to the pin 4, and the rotating head 2 12 is rotatably connected to the pin 4. The pin 4 passes through the shaft hole 2 and plays a key role in connecting the two rotating heads. One end of the pin 4 is threadedly connected to the shaft hole 2 on the rotating head 11, so that the rotating head 11 and the pin 4 are fixed. The nail cap 5 at the other end limits the position of the rotating head 2 12 so that it can rotate relatively around the pin 4.

[0022] This adjustable double-head pipe connector achieves flexible angle adjustment and reliable connection through a unique structural design.

[0023] A connection groove 6 is provided on one end face of the connector 3 away from the rotating head, and the tubular part is inserted into the connection groove 6. A positioning hole 7 is provided on the side wall of the connector 3, and the positioning hole 7 is connected to the connection groove 6. The internal thread of the positioning hole 7 is connected with a positioning screw, and the positioning screw is tightened to position and fix the inserted pipe. The shape and size of the connection groove 6 will match the shape and size of the end of the tubular part to be connected to provide a good fit and preliminary positioning. The position of the positioning hole 7 on the side wall of the connector 3 is usually selected at a position where the tightening force can be effectively applied, and the number may vary depending on the size of the connector and the required tightening strength. When the positioning screw is tightened, pressure can be directly applied to the tubular part inserted into the connection groove 6, thereby achieving firm positioning and fixing. The combined design of the connection groove 6, the positioning hole 7 and the positioning screw provides a simple, effective and reliable fixing method for the connection between the tubular part and the connector 3.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
