[0033] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] like Figure 1-Figure 5 As shown together, the pipeline with a connector proposed in this embodiment can be a temporary water pipe, oil pipe or other transportation pipeline, or can be other pipelines.

[0035] There are no additional components at both ends of an ordinary pipe. The pipe with a connector is provided with a first connector 1 and a second connector 2 at both ends of the ordinary pipe respectively. The first connector 1 and the second connector 2 are connected to each other to realize rapid docking of adjacent pipes, without the need to find additional connectors, thus saving time and labor costs.

[0036] The pipeline can be cut into appropriate lengths according to the construction conditions, and the first connector 1 and the second connector 2 can be processed on both ends of the pipeline respectively, so as to mass produce the pipeline with connectors.

[0037] Specifically, the first connector 1 may include a pipe sleeve block 3 and a locking block 4 connected to the outer wall of the pipe sleeve block 3, the inner diameter of the pipe sleeve block 3 is the same as the outer diameter of the pipe 9, the locking block 4 includes a rectangular block, a locking hole 5 is provided at one end of the rectangular block in the length direction, and a locking tongue 6 is provided at the other end, the pipe sleeve block 3 is sleeved on the outside of one end of the pipe 9, and the rectangular block is along the length direction of the pipe 9. The second connector 2 is formed by rotating the first connector 1 180° around a straight line perpendicular to the pipe 9, and the pipe sleeve block of the second connector 2 is sleeved on the outside of the other end of the pipe 9.

[0038] The pipe sleeve block 3 of the first connector 1 is connected to the pipe sleeve block of the second connector 2 of the adjacent pipe, the locking block 4 of the first connector 1 is fitted to the locking block of the corresponding second connector 2, and the corresponding locking tongues and locking blocks are fixedly connected.

[0039] The first connector 1 and the second connector 2 have the same structure. One of them is flipped 180 degrees, and the pipe sleeve blocks 3 of the two connectors can be docked to complete the docking of the pipe 9, and the two locking blocks are interlocked to achieve locking and fixing of the docking.

[0040] The pipe sleeve block 3 is used to connect the support locking block 4, and at the same time, it is sleeved on the pipe 9 to play the role of a joint. The outer circumference of the pipe sleeve block 3 is slightly larger than the outer circumference of the pipe 9, and the center hole of the pipe sleeve block 3 is just sleeved on the outer wall of the pipe 9. The pipe sleeve block 3 has a certain wall thickness, which can increase the docking area of ​​the pipe sleeve block 3 and has strong docking sealing.

[0041] The locking block 4 can be made of a rectangular block, the length direction of the rectangular block is along the height direction of the pipe sleeve block 3, and the narrower side of the rectangular block in the length direction is connected to the pipe sleeve block 3. A locking hole 5 is opened at one end of the wider surface in the length direction of the rectangular block, and the locking hole 5 is used to fix the locking tongue 6. The locking tongue 6 is arranged at the other end of the wider surface in the length direction of the rectangular block, and the locking tongue 6 is adapted to the locking hole 5.

[0042] When docking two pipes, the first connector 1 of one pipe is connected to the second connector 2 of the other pipe, the pipe sleeve blocks of the first connector 1 and the second connector 2 are docked together, the locking blocks of the first connector 1 and the second connector 2 are opposite to each other and fit together, the locking tongue 6 of the first connector 1 is opposite to and fixedly connected with the locking hole of the second connector 2, the locking hole 5 of the first connector 1 is opposite to and fixedly connected with the locking tongue of the second connector 2, the double lock connection, the first connector 1 and the second connector 2 are more firmly connected, so that the pipes are firmly docked together, reducing the risk of loose pipe connections.

[0043] After the construction is completed, the first connector 1 and the second connector 2 are separated, and the pipe 9 and the connectors will not be damaged and can be reused, thus saving costs.

[0044] The pipe sleeve block 3 and the locking block 4 can be made of metal or alloy to adapt to different use environments and requirements. The inner diameter and outer diameter of the pipe sleeve block 3 can be set according to the outer diameter of the pipe 9.

[0045] In a specific embodiment of the utility model, in order to facilitate the connection between the lock tongue 6 and the lock hole 5, the lock tongue 6 may include a support block 61 and a round rod 62 arranged on the first side surface of the support block 61, and a rotating shaft 63 is arranged on the second side surface and the third side surface adjacent to the first side surface. Two shaft seats 64 are arranged on the end surface of the rectangular block in the length direction, and the support block 61 is located between the two shaft seats 64. The rotating shaft 63 is passed through the corresponding shaft seat 64, and the rotating shaft 63 can be limited in the shaft seat 64 for rotation.

[0046] The round rod 62 is a component inserted into the lock hole 5. The round rod 62 can be inscribed with the edge of the first side surface of the support block 61. The central axis of the round rod 62 and the central axis of the length direction of the rectangular block are on the same plane. The support block 61 is located exactly between the two shaft seats 64. The rotating shaft 63 rotates in the shaft seat 64, and the support block 61 rotates between the two shaft seats 64, so that the round rod 62 can swing, which facilitates the round rod 62 to be flexibly inserted into and pulled out of the lock hole 5. The length of the round rod 62 can be extended into the lock hole 5.

[0047] In a specific embodiment of the present invention, in order to facilitate the support block 61 to rotate smoothly between the two shaft seats 64, the side of the support block 61 that is away from the round rod 62 is an arc surface, and the arc surface can rotate in the space formed by the end face of the rectangular block and the two shaft seats 64.

[0048] In order to cooperate with the round rod 62, the locking hole 5 may include a U-shaped groove 51 opened inwardly in the middle of the end face of the rectangular block, the inner diameter of the bottom of the U-shaped groove 51 is the same as the outer diameter of the round rod 62, a through hole 52 is provided on one side wall of the U-shaped groove 51, a limiting rod 53 is passed through the through hole 52, the limiting rod 53 is tightly pressed against the other side wall of the U-shaped groove 51, and the distance between the limiting rod 53 and the bottom of the groove is equal to the outer diameter of the round rod 62.

[0049] The U-shaped groove 51 is a lock hole for inserting the round rod 62. The inner size of the U-shaped groove 51 just accommodates the round rod 62. When the round rod 62 swings to be perpendicular to the lock plate, it can be inserted into the bottom of the U-shaped groove 51, and the round rod 62 is stuck in the arc bottom of the U-shaped groove 51. The limit rod 53 is a lock, which blocks the upper side of the round rod 62 in the U-shaped groove 51 to prevent the round rod 62 from moving out of the U-shaped groove 51.

[0050] In order to reduce the use of tools and achieve quick connection and disassembly, the limit rod 53 can move in the lock body through hole 52 on one side of the U-shaped groove 51. When the limit rod 53 moves outward, the round rod 62 can swing into or out of the U-shaped groove 51. When the limit rod 53 moves inward, it can press against the other side of the U-shaped groove 51.

[0051] In a specific embodiment of the utility model, in order to facilitate the movement of the limiting rod 53, the limiting rod 53 may include a rod portion 531 passed through the through hole 52 and a rod cap 532 connected to one end of the rod portion 531, and a tension spring 533 is connected between the rod cap 532 and the rectangular block. When the tension spring 533 is in a free state, the rod portion 531 is pressed against the inner wall of the U-shaped groove 51.

[0052] The two ends of the tension spring 533 are connected to the rod cap 532 and the outer wall of the rectangular block respectively, and the limit rod 53 will not be separated from the through hole 52, and will always be inserted into the through hole 52. When it is necessary to separate or lock the two locking blocks 4, the rod cap 532 is pulled, the tension spring 533 is extended, the rod 531 is separated from the inner wall of the U-shaped groove 51, and the round rod 62 swings to insert or leave the U-shaped groove 51; when the rod cap 532 is released, the tension spring 533 returns to its original position and is in a free state, and the rod 531 just presses against the inner wall of the U-shaped groove 51. The round rod 62 can be locked by pulling the rod cap 532, which is easy and quick.

[0053] In a specific embodiment of the present invention, in order to ensure that the two locking blocks 4 can fit stably, the surface where the pipe sleeve block 3 is connected to the rectangular block is a plane, and the side of the rectangular block without the U-shaped groove 51 is connected at half of the plane.

[0054] When the first connector 1 and the second connector 2 are connected, the planes of the two pipe sleeve blocks 3 are aligned, the two pipe sleeve blocks 3 are docked, and the two locking blocks 4 fit together exactly. The limiting rod 53 is pulled, and the corresponding round rod 62 is rotated to be perpendicular to the locking block 4 and inserted into the U-shaped groove 51. The rod cap 532 is loosened, and the tension spring 533 returns to its original position. The limiting rod 53 presses on the inner wall of the U-shaped groove 51 to restrict the round rod 62 in the U-shaped groove 51. The locking blocks of the first connector 1 and the second connector 2 are fixed to each other, and the pipe sleeve blocks 3 of the first connector 1 and the second connector 2 are tightly docked, and the connection of the two pipes is completed.

[0055] In a specific embodiment of the present invention, in order to ensure stable docking of the pipe sleeve block 3, the height of the pipe sleeve block 3 is not greater than half of the distance between the arc bottom and the shaft seat 64. The height of the pipe sleeve block 3 should not be too long. After the pipe sleeve blocks 3 of the first connector 1 and the second connector 2 are docked, the two opposite locking blocks 4 should be able to lock each other.

[0056] In a specific embodiment of the utility model, in order to achieve good sealing after docking, one end of the pipe 9 extends out of the pipe sleeve block 3 of the first connector 1, and the other end of the pipe 9 is in the pipe sleeve block of the second connector 2. The sum of the length of the pipe extending out of the pipe sleeve block 3 of the first connector 1 and the length of the pipe in the pipe sleeve block of the second connector 2 is the height of the pipe sleeve block 3. After the pipe sleeve blocks 3 of the first connector 1 and the second connector 2 are docked, the pipe 9 is just docked, and the docking seam is located inside the pipe sleeve block 3, and is offset from the docking seam of the pipe sleeve block, so that liquid is less likely to flow out.

[0057] In a specific embodiment of the utility model, a sealing ring 7 is provided on the side of the pipe sleeve block 3 of the first connector 1 to be connected. The joint between the pipe sleeve blocks of the first connector 1 and the second connector 2 is sealed by the sealing ring 7, which further improves the sealing performance. The thickness of the sealing ring 7 should not be too thick, and can be within 1 mm.

[0058] In a specific embodiment of the present utility model, in order to firmly connect the pipe sleeve block 3 and the pipe 9, a reinforcing pipe 8 is provided between the non-jointed side of the pipe sleeve block 3 and the outer wall of the pipe 9. The reinforcing pipe 8 is integrated with the pipe sleeve block 3, thereby increasing the sleeve connection area between the pipe sleeve block 3 and the pipe 9, and making the sleeve connection of the pipe sleeve block 3 more firmly.
