[0009] Figure 1 The RTP composite pipeline port quick docking structure is more time-saving and labor-saving compared with the two flanges locked by bolts and nuts. DETAILED DESCRIPTION

[0010] The RTP composite pipeline port quick docking structure is more time-saving and labor-saving compared with the two flanges locked by bolts and nuts.

[0011] As Figure 1As shown, the RTP composite pipe port quick docking structure comprises bolt holes 12 arranged on one flange 7, fixing bolts 13 arranged on the other flange 7, and the bolt holes 12 and the fixing bolts 13 are usually arranged in multiple numbers and arranged around the flanges 7; the fixing bolt 13 comprises a cylindrical shell 14, the rear end of the cylindrical shell 14 is fixed with the flange 7, a movable rod 15 capable of moving forward and backward is arranged in the cylindrical shell 14, a hinged frame 16 is arranged on the movable rod 15, four backward inclined struts 17 are respectively hinged around the hinged frame 16, the four struts 17 are evenly arranged, the inner end of each strut 17 is hinged with the hinged frame 16, the outer end of each strut 17 respectively extends out of the cylindrical shell 14 through the through slot 18 arranged on the cylindrical shell 14, the elastic rubber block 19 is arranged between each strut 17 and the movable rod 15, the limiting block for limiting the outward swinging angle of the strut 17 is further arranged on the left and right sides of the hinged frame 16, the maximum angle of outward swinging of each strut 17 is not more than 45 degrees under the limiting of each limiting block, the elastic rubber block 19 pads the strut 17 until the strut 17 swings outward to abut against the limiting block, the strut 17 can swing inward to be folded in the cylindrical shell 14 after being pressed to overcome the elastic force of the elastic rubber block 19, the two ends of the movable rod 15 respectively extend out of the front and rear ends of the cylindrical shell 14, and the rear end of the movable rod 15 further penetrates the flange 7, the spring seat 20 in the cylindrical shell 14 is arranged on the front part of the movable rod 15, the spring 21 is arranged on the movable rod 15 and sleeved on the spring seat 20 and the front end of the cylindrical shell 14, the two ends of the spring 21 respectively abut against the spring seat 20 and the front end of the cylindrical shell 14, the limiting hole 22 is arranged on the movable rod 15, and the limiting rod 23 capable of being inserted into the limiting hole 22 is arranged on the cylindrical shell 14 in a pluggable manner, the limiting rod 23 can limit the movable rod 15 after being inserted into the limiting hole 22.

[0012] Two composite pipes are connected by two flanges. When the two flanges 7 are connected, each fixed plug 13 is opposite to the corresponding bolt hole 12, then the worker overcomes the spring 21 force and presses the rear end of the moving rod 15, so that the moving rod 15 moves forward with each foot support 17 through the bolt hole 12. When each foot support 17 passes through the bolt hole 12, the bolt hole 12 will press each foot support 17 inward, and after passing through the bolt hole 12, each foot support 17 is reset and opened under the action of the respective elastic rubber block 19. Then each foot support 17 can resist the flange 7 where the bolt hole 12 is located under the action of the spring 21, so that the two flanges 7 can be close to each other. Then insert the limiting rod 23 on each fixed plug 13 into the limiting hole 22, at this time the two flanges 7 can be locked by each fixed plug 13 and the corresponding bolt hole 12. When the two composite pipes need to be separated, pull out each limiting rod 23, then continue to press the rear end of each moving rod 15 by the worker, so that the moving rod 15 continues to move forward with the foot support 17. At this time, the side wall of the cylindrical shell 14 can press the foot support 17, so that the foot support 17 can be folded in the cylindrical shell 14 as the moving rod 15 moves forward. At this time, each fixed plug 13 can exit the corresponding bolt hole 12 so that the two flanges 7 can be separated. The worker presses the front end of the moving rod 15 to make the moving rod 15 move backward, so that each foot support 17 can be opened again by leaving the cylindrical shell 14, so that the fixed plug 13 can continue to be used.
