Description

Technical Field

[0001] This utility model relates to the field of carbon steel pipe technology, specifically to a carbon steel pipe that is easy and quick to connect. Background Technology

[0002] Carbon steel pipes, also known as carbon steel tubes, are made by piercing steel ingots or solid tube blanks to form rough tubes, which are then hot-rolled, cold-rolled, or cold-drawn. Carbon steel pipes hold an important position in my country's steel pipe industry and are widely used.

[0003] Patent document CN211219450U discloses a butt-jointing positioning device for welding carbon steel pipes. In use, one end of the pipe is clamped between an upper and lower semi-circular plate. The pipe to be joined is then placed on a guide plate for easy operation. The butt-jointing effect is good. Before butt-joining, a level is used to check if the base surfaces are level. Then, a telescopic ruler is used to measure the distance. After measurement, the telescopic ruler is pulled to the same value, indicating that it serves as a reference for positioning, thus improving the positioning effect. Welding is convenient; welding can begin immediately after positioning. The top of the pipe can be welded first. After the top is welded, the pipe connection structure is stable. The device can then be removed, and the bottom of the pipe can be welded.

[0004] However, the device cannot quickly connect carbon steel pipes, and after connecting the carbon steel pipes, it cannot further improve the sealing of the carbon steel rail connection. In addition, it cannot monitor or alarm the carbon steel rail during the connection process, resulting in low safety of the device. Utility Model Content

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example: Refer to Figures 1 to 3 A carbon steel pipe that is easy and quick to connect includes a carbon steel pipe 101; a docking mechanism is installed on the outer surface of the carbon steel pipe 101, the docking mechanism consists of a docking component, a sealing component and a protective component, the docking component is installed on the outer surface of the carbon steel pipe 101, the sealing component is installed on the outer surface of the carbon steel pipe 101, and the protective component is installed on the outer surface of the carbon steel pipe 101.

[0024] The sealing assembly includes a lower sealing housing 301, which is fixedly connected to the outer surface of the carbon steel pipe 101. A rotating shaft 302 is rotatably connected to the top of the lower sealing housing 301. An upper sealing housing 303 is rotatably connected to the outer surface of the rotating shaft 302. A threaded hole is provided on the inner side of the upper sealing housing 303, and a screw 304 is installed inside the threaded hole. A nut 305 is threaded onto the outer surface of the screw 304. A sealing ring 306 is fixedly connected to the inner side of the upper sealing housing 303. A pressure tester 307 is connected to the top of the upper sealing housing 303. By installing the sealing assembly, the sealing effect is further enhanced. After the carbon steel pipes are connected, the upper sealing housing 303 is rotated around the rotating shaft 302, causing the upper sealing housing 303 to contact the lower sealing housing 301. The screw 304 is then inserted into the threaded hole, and the nut 305 is rotated to connect the nut 305 to the screw 304. This, together with the sealing ring 306, seals the carbon steel pipe 101. At the same time, the pressure tester 307 can monitor the sealing performance of the carbon steel pipe 101 connection at all times, thereby improving the safety of the device.

[0025] The docking assembly includes a docking plate 201, which is fixedly connected to the port of the carbon steel pipe 101. A screw 202 is movably connected inside the docking plate 201, and a nut 203 is movably connected to the outer surface of the screw 202. By aligning the docking plates 201 at the ports of the two carbon steel pipes 101, and further connecting them by threading the screw 202 and the nut 203, multiple carbon steel pipes 101 can be quickly connected.

[0026] The protective components include an alarm 401, which is fixedly connected to the top of the sealed upper housing 303. An alarm light 402 is fixedly connected to the top of the alarm 401. A motor 403 is fixedly connected to the outer surface of the carbon steel pipe 101. A blocking flange 404 is fixedly connected to the output shaft of the motor 403. A connecting block 405 is movably connected to the other end of the blocking flange 404. By installing the alarm 401, the connection point can be further detected. When a leak occurs at the connection point of the carbon steel pipe 101, the motor 403 and the alarm 401 are activated. The alarm 401 will sound an alarm, the alarm light 402 will illuminate, and the motor 403 will start, causing the blocking flange 404 to rotate, thereby sealing the carbon steel pipe 101 and preventing leakage, thus further improving the safety of the device.

[0027] The alarm 401 is electrically connected to the motor 403. A ball bearing is installed inside the connecting block 405. The inner ring of the ball bearing is connected to the blocking flange 404. When the alarm 401 sounds, the motor 403 starts at the same time, thereby driving the blocking flange 404 to rotate, thus further improving the safety of the device.

[0028] A sealing strip is installed on the outer surface of the blocking flange 404. The diameter of the blocking flange 404 is the same as the diameter of the carbon steel pipe 101. Therefore, when the motor 403 is started and drives the blocking flange 404 to rotate, the carbon steel pipe 101 can be completely blocked through the blocking flange 404.

[0029] The working principle of this utility model is as follows: The mating plates 201 at the ends of two carbon steel pipes 101 are aligned, and then screws 202 and nuts 203 are threaded together to quickly connect multiple carbon steel pipes 101. The upper sealing housing 303 is rotated around the rotating shaft 302, causing it to contact the lower sealing housing 301. Screws 304 are inserted into the threaded hole, and nuts 305 are rotated to thread them together with screws 304. This, in conjunction with the sealing ring 306, seals the carbon steel pipe 101. Simultaneously, the pressure tester 307 continuously monitors the sealing performance of the carbon steel pipe 101 connection, thereby improving the safety of the device. When a leak occurs at the connection of the carbon steel pipe 101, the motor 403 and alarm 401 are activated. The alarm 401 sounds, the alarm light 402 illuminates, and the motor 403 is activated, causing the blocking flange 404 to rotate, thus sealing the carbon steel pipe 101 and preventing leakage, further enhancing the safety of the device.
