Improved construction of fluid transfer pipe movable joint

This creation relates to the construction of a joint, and more particularly to an improved construction of a fluid transfer tube movable joint.

The joint of the general fluid delivery tube can be integrally formed or fixed as shown in FIG. 1 , which means that the fluid delivery tube joint 100 ′ is integrally fixed or fixed, that is, the fluid delivery tube joint 100 is relatively fixed. One end is connected to the oil reservoir 200, and the other end is connected to the fluid delivery tube 300.

Since the fluid delivery pipe joint 100' is fixed, if the oil storage tank 200 moves, the fluid delivery pipe 300 will be distorted or wound up to affect its conveying efficiency; further, if it is an integrally formed fluid conveying pipe In the case of a joint, the manufacturing method of integral molding is relatively difficult, and the defective rate is increased, which in turn affects the cost.

Please refer to the new patent No. M364153 of the Republic of China, which discloses a "movable pipe joint" which includes a sleeve, a first joint and a second joint, and a ring groove is arranged in the inner ring of the second joint. And a plurality of beads are placed in the ring groove, and a protrusion is disposed outside the second joint, the protrusion has a first wall surface, and the first wall surface is attached to the plurality of beads of the ring groove to make the second joint Rotating relative to the sleeve; the second joint can be rotated 360 degrees, so that the tubes connected to the first joint and the second joint do not interfere with each other, causing distortion and winding The situation occurs to ensure the smoothness of the inside of the pipe.

Although the "active pipe joint" disclosed in the above patent can avoid the occurrence of distortion and winding, to ensure the smoothness of the inside of the pipe body, the assembly of components such as balls is complicated and difficult, and it is easy to affect the production capacity and good quality. Rate, which in turn affects costs.

In order to solve the above problems, an object of the present invention is to provide an improved structure of a fluid conveying pipe movable joint, which not only has a simple structure and convenient assembly, but also utilizes the internal thread portion of the first ring and the external thread portion of the second ring.
