[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figures 1-6 A fastening and anti-loosening type connector, comprising a flange 1 arranged on a pipeline, a symmetrically arranged frame 2 is mounted on the flange 1, a guide rod 3 is fixedly mounted in the frame 2, and a pressure plate 4 that is movably abutted against the flange 1 is slidably sleeved on the guide rod 3;

[0024] The guide rod 3 is horizontally arranged at both ends of the frame 2, the pressure plate 4 is a semi-annular structure, a handrail is fixedly installed on the frame 2, a spring 5 matched with the guide rod 3 is welded between the frame 2 and the pressure plate 4, and the spring 5 is sleeved on the guide rod 3, the guide rod 3 guides the pressure plate 4, so that the pressure plate 4 can smoothly resist the flange 1 when moving;

[0025] The sliding sleeve on the frame 2 is provided with a guide plate 6 connected to the pressure plate 4, and the sliding sleeve on the frame 2 is provided with a limit frame 7 connected to the middle end of the pressure plate 4, and the limit frame 7 is a T-shaped structure. The guide plate 6 and the limit frame 7 cooperate with each other to guide the moving pressure plate 4, thereby ensuring the moving direction of the pressure plate 4;

[0026] A pressure component for applying pressure to the pressure plate 4 is installed in the flange 1;

[0027] The pressure assembly includes a vertical plate 8 fixedly mounted on the frame 2, and a positioning rod 9 is rotatably mounted on the vertical plate 8, and a resisting rod 10 that resists the pressure plate 4 is fixedly mounted on the positioning rod 9. By rotating the resisting rod 10, the end of the resisting rod 10 close to the pressure plate 4 can resist the pressure plate 4, so that the pressure plate 4 can press the flange 1 on the inner side of the frame 2 when moving;

[0028] The frame 2 is provided with a clamp assembly for clamping one end of the resistance rod 10;

[0029] The positioning rod 9 is horizontally arranged at one side of the pressure plate 4, and the clamp assembly includes a moving groove 11 and a positioning groove 12 which are opened in the frame 2 and communicated with each other. A sliding sleeve is provided on the resistance rod 10 with a sliding rod 13 extending into the positioning groove 12, and a second spring 14 is welded between the sliding rod 13 and the resistance rod 10. The second spring 14 is vertically arranged at one side of the sliding rod 13 extending into the resistance rod 10, and a moving block connected to the sliding rod 13 is provided in the resistance rod 10. The resistance rod 10 guides the moving block, so that the moving block can smoothly pull the sliding rod 13 when moving;

[0030] When deflected, the resistance rod 10 can resist the pressure plate 4, so that the pressure plate 4 can limit the flange 1 in the frame 2, thereby ensuring the sealing between the two flanges 1 and effectively improving the efficiency of pipeline transportation. When the resistance rod 10 tends to be horizontal, the resistance rod 10 drives the sliding rod 13 to extend into the positioning groove 12, and then the spring 14 is extended and retracted to make one end of the resistance rod 10 always able to resist the pressure plate 4.

[0031] The functional principle of the utility model can be explained through the following operation modes:

[0032] Apply pressure to the handrail so that the handrail drives the frame 2 to move to the positions on both sides of the flange 1, so that the two corresponding flanges 1 can be located in the gap between the pressure plate 4 and the frame 2;

[0033] Manually apply pressure to one end of the resistance rod 10, so that the resistance rod 10 drives the positioning rod 9 to rotate on the vertical plate 8. When the resistance rod 10 rotates, the end close to the pressure plate 4 can resist the pressure plate 4, so that the pressure plate 4 slides on the guide rod 3. The spring 1 5 is stressed, and the pressure plate 4 can resist the two corresponding flanges 1 to the inner side of the frame 2 when moving;

[0034] When the pressure plate 4 moves, it drives the two guide plates 6 to slide on the frame 2, and the pressure plate 4 drives the limit frame 7 to slide on the middle end of the frame 2;

[0035] At the same time, when the resisting rod 10 is deflected, the other end drives the slide bar 13 to slide in the moving groove 11, and the slide bar 13 drives the moving block to slide in the resisting rod 10. When the resisting rod 10 tends to be horizontal, it can drive the slide bar 13 to extend into the positioning groove 12, and the spring 14 is stressed. Through the mutual cooperation between the positioning groove 12 and the slide bar 13, the resisting rod 10 can always be in contact with the pressure plate 4.

[0036] Pipelines can be used for transportation operations.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
