[0002] The built-in quick connection structure of the cable seamless metal pipe is a joint that can connect or disconnect the pipeline without tools. It allows the cable metal pipe to be quickly assembled and disassembled according to actual needs, effectively improving the practicality of the cable seamless metal pipe so that it can protect cables of different lengths. The built-in quick connection structure of the cable seamless metal pipe can be divided into quick connectors for air, quick connectors for oxygen and fuel gas, quick connectors for gas and liquid, quick connectors for oil pressure, quick connectors for inert gas, quick connectors for cooling water temperature oil, and quick connectors for semiconductors.

[0003] However, it still has some disadvantages. For example, the connection between two pipelines in traditional metal pipes is mostly flange connection. Although flange connection can be used for large-diameter high-pressure transmission, it is heavy, inconvenient to install and carry, and the connection speed is not fast and convenient enough, which reduces the use efficiency of metal pipes. In addition, since the two are rigidly connected, the connection speed is slow, the work efficiency is low, it is not easy to bend or change the angle, and it cannot adapt to the uneven working environment with a small bending radius, which fully reduces the practicality of metal pipes.

[0004] In order to solve the above problems, the present application proposes a cable seamless metal pipe built-in quick connection structure. Utility Model Content

[0012] Preferably, an elastic card is fixedly connected to the outer surface of the right end of the threaded tube, and a circular tube is movably sleeved on the inner wall of the elastic card.

[0013] Preferably, a butt-joint tube is fixedly connected to the outer surface of the right end of the circular tube, and an adjusting tube is fixedly connected to the outer surface of the right end of the butt-joint tube.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model cooperates with the U-shaped groove by the provided clamping bolt, so that the right connecting pipe can be sleeved on the outer surface of the right end of the left connecting pipe, and then the U-shaped groove is aligned with the clamping bolt, so that the right connecting pipe can drive the connecting inner pipe to be embedded in the inner wall of the left connecting pipe. Finally, the right connecting pipe is rotated clockwise, and the connecting inner pipe is bounced toward the outer wall by the spring telescopic rod through the fixed clamp ring, so that the clamping bolt is clamped in the inner side of the U-shaped groove, so that the right connecting pipe can be fixed to the outer surface of the right end of the left connecting pipe. The installation and connection are simple and fast, and the use efficiency of the metal pipe is effectively improved.

[0016] The utility model cooperates with the circular tube by setting the elastic card so that the circular tube can be clamped into the inner wall of the elastic card, so that the circular tube can rotate freely on the inner wall of the elastic card, so that the metal pipe can be bent and the angle can be easily changed when in use, so that it can adapt to the working environment with uneven height and small bending radius, and the practicality of the metal pipe is effectively improved. Then the adjusting sleeve is rotated to the right so that the adjusting sleeve can be sleeved on the outer wall of the elastic card, so that the elastic card is fixed, and the adjusting tube is effectively prevented from falling off from the inner wall of the elastic card when in use.
