The end of the connecting pipe head away from the external pipe head is connected to a connecting pipe, and the end of the external pipe head close to the connecting pipe head is connected to a male head with an internal diameter gradually shortened and decreasing. Each layer of the top surface of the male head is connected to a circle of sealing ring, and the bottom of the connecting pipe head is connected to a female head that is adapted to the outer cylinder of the male head and threadedly connected; in the utility model, the outer stepped surface of the male head is multi-end threadedly sealed with the inner side corresponding to the female head, so that the connection between the connecting pipe head and the external pipe head is fixed in multiple sections. Even if the outer surface of the outer end of the male head is thread-slipped, it will not affect the fixing effect between the male head and the female head. The cooperation of the male head, the female head and the sealing ring can enhance the sealing performance and fixing efficiency of the connection between the connecting pipe head and the external pipe head;

[0004] However, when using existing pipe joints, the joints are usually docked once in a complicated manner. If the joints are undocking, they cannot be quickly reconnected. That is, the effect of quick release cannot be achieved when the joints need to be undocking, which limits the work of pipe docking. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The utility model provides Figure 1-4 The oil pipeline joint shown in the figure includes a female joint 1 and a sub-joint 2. The opposite ends of the female joint 1 and the sub-joint 2 are fixedly connected with a pipe fixing head 8. One end of the female joint 1 is fixedly connected with a fixing ring 3. Both sides of the interior of the fixing ring 3 are provided with a clamping structure 4, which can make the female joint 1 and the sub-joint 2 form a docking tendency. Both sides of the surface of the sub-joint 2 are provided with a docking structure 5, which can ensure the firmness when the female joint 1 and the sub-joint 2 are completed. The utility model makes the two pipes that need to be docked fixedly connected to the interior of the female joint 1 and the sub-joint 2, and then one end of the sub-joint 2 is inserted into the female joint 1. To enter the interior of the female connector 1, first align the clamping block 405 with the docking groove 9 opened on one side of the surface of the docking block 503, and then rotate the two control rods 403 to make the threaded sleeve 402 drive the threaded push rod 404 to retract, so that the sub-connector 2 can enter the interior of the female connector 1. The docking is made firm according to the rotation of the threaded sleeve 402. To release the docking, only the threaded sleeve 402 needs to be rotated in the opposite direction, avoiding the problem that most pipe connectors cannot produce a quick-release effect, thereby improving the flexibility of the docking between pipes. At the same time, the flexibility also ensures that the docking between pipes remains firm.

[0022] like Figure 2-3As shown, the two clamping structures 4 each include a working cavity 401, a threaded sleeve 402, and a control rod 403. The two working cavities 401 are both opened on both sides of the interior of the female connector 1. The two threaded sleeves 402 are both rotatably connected to one side of the inner wall of the working cavity 401. The two control rods 403 are both fixedly connected to one side of the surface of the two threaded sleeves 402, and one end of the two control rods 403 respectively penetrates the interior of the fixing ring 3 and extends to the outside. The two clamping structures 4 also include a threaded push rod 404 and a clamping block 405. The two threaded push rods 404 are both threadedly connected to the interior of the two threaded sleeves 402, and one end of the two threaded push rods 404 respectively penetrates the interior of the fixing ring 3 and extends to the outside. The two clamping blocks 405 are respectively fixedly connected to one end of the two threaded push rods 404.

[0023] like Figure 4 As shown, the two docking structures 5 both include a fixing groove 501 and a spring 502. The two fixing grooves 501 are both opened on both sides of the surface of the sub-connector 2. The two springs 502 are both fixedly connected to one side of the inner wall of the fixing groove 501. The two docking structures 5 both include a docking block 503. The two docking blocks 503 are both fixedly connected to one side of the spring 502, and one side of the surface of the docking block 503 is slidably connected to the inner wall of the fixing groove 501. The setting of the spring 502 can enable the female connector 1 and the sub-connector 2 to dock without causing strain.

[0024] like Figure 1 、 Figure 2 and Figure 4 As shown, limiting grooves 6 are provided on both sides of the inner walls of the two working cavities 401, and the inner walls of the multiple limiting grooves 6 are slidably connected to limiting blocks 7. The limiting blocks 7 can enable the threaded push rod 404 to produce a limiting effect when moving. Two opposite sides of one side of the multiple limiting blocks 7 are fixedly connected to the surface of the threaded push rod 404. A docking groove 9 is provided on one side of the surface of the two docking blocks 503, and the two docking grooves 9 are respectively matched with the surfaces of the two clamping blocks 405. Extension openings 10 are provided on both sides of the surface of the fixing ring 3. The opening of the extension opening 10 can enable the clamping block 405 to be stored inside when not in use.

[0025] Working principle of the utility model: When using the utility model, first fix the female connector 1 and the sub-connector 2 on the two ends of the pipes to be connected, and then when connecting, first insert the sub-connector 2 into the interior of the female connector 1, and at the same time, the clamping block 405 needs to be inserted into the docking groove 9 opened on one side of the surface of the docking block 503;

[0026] When the connection is completed, the threaded sleeves 402 on both sides of the sub-connector 2 are rotated immediately. By rotating the threaded sleeves 402, the threaded sleeves 402 drive the threaded push rods 404 to produce a contraction movement effect. When the threaded push rods 404 move, a limiting effect is produced by the limit blocks 7 fixedly connected on both sides of the rod wall. Finally, when the threaded push rods 404 move, the clamping block 405 fixedly connected on one side will also drive the docking block 503 to move, so that the sub-connector 2 can extend into the interior of the female connector 1, thereby forming a connection.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
