[0005] To achieve the above purpose, the utility model provides a limit protection pipe joint, which includes a first limit ring, a second limit ring, an outer protection tube and a mounting block. One end of the first limit ring is rotatably connected to one end of the second limit ring, and the other end of the first limit ring is adapted to the other end of the second limit ring. The first limit ring and the second limit ring are both sleeved outside the outer protection tube. One end of the mounting block is fixedly connected to the second limit ring and is located below the second limit ring. The mounting block has a plurality of mounting holes.

[0006] Wherein, the limit protection pipe joint further includes a plurality of X-shaped strengthening blocks, and the plurality of X-shaped strengthening blocks are all fixedly connected to the first limit ring and are sequentially distributed on the inner wall of the first limit ring.

[0007] Wherein, the outer protection tube includes a first tube body and a second tube body, the first tube body is adapted to the second tube body, the outer surface wall of the first tube body is mutually attached to the inner wall of the first limit ring, and the outer surface wall of the second tube body is mutually attached to the inner wall of the second limit ring.

[0008] Wherein, the outer protection tube further includes a plurality of connection holes, and the plurality of connection holes are respectively fixedly connected to the first tube body and the second tube body and are sequentially located on the outer surface walls of the first tube body and the second tube body.

[0009] Wherein, the outer protection tube further includes two nameplates, and the two nameplates are respectively fixedly connected to the first tube body and the second tube body, and are respectively located on the outer walls of the first tube body and the second tube body.

[0010] For a limit protection pipe joint of the present utility model, the first limit ring and the second limit ring are engaged to complete fixation, and are in clearance fit with the inner outer protection tube, so that the outer protection tube can move back and forth. Through the mounting holes of the mounting blocks, it can be fixed on the support member on the robot to complete the installation. Thus, the outer protection tube is installed in the limiting device. While not restricting the back-and-forth movement of the outer protection tube, the lateral movement of the outer protection tube in other directions is restricted, reducing the direct friction between the outer protection tube and the robot body and extending the service life of the outer protection tube.
