Description

Technical Field

[0001] The utility model relates to the technical field of water pipe connection, and more specifically, to a water delivery pipe fitting connection structure. Background Art

[0002] After the main body of the pipeline is completed, the direction in which the connecting pipes derived from its side walls can be connected is often fixed, and it can only be connected to water pipes in a single direction, so its scope of application is relatively small.

[0003] In response to the above problems, a Chinese patent with publication number CN218523202U discloses a pipe connector, which includes a connector body, one end of the connector body is provided with a water inlet, and the other end is closed, and a plurality of branch water outlet pipes are evenly distributed on the outer peripheral wall of the connector body along the circumferential ring of the connector body, the inner diameters of the plurality of branch water outlet pipes are the same, and the plurality of branch water outlet pipes are all connected to the connector body.

[0004] The above solution has the effect of improving the applicability of the water pipe connector.

[0005] At the same time, the utility model proposes a new solution to solve this problem. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a water pipe connection structure, which drives the connecting pipe to rotate to correspond to connecting ports in different orientations by providing a rotatable ring, so that the connecting pipe can be connected to pipes in different orientations, which is suitable for use in more situations.

[0007] The above technical purpose of the utility model is achieved through the following technical solutions: a water delivery pipe connection structure, including a connector, the connector including a pipe body, the pipe body is provided with a plurality of connecting ports distributed in a ring array, the outer wall of the pipe body is sleeved with a collar rotatably connected thereto, the collar is provided with a docking port consistent with the shape and size of the connecting port, a connecting pipe slidably connected thereto is provided in the docking port, when the collar is rotated until the docking port corresponds to the connecting port, the connecting pipe is inserted into the connecting port, and a limiting mechanism is provided between the connecting pipe and the connecting port.

[0008] By adopting the above technical solution, during the use of the connector, the ring sleeved on the outside of the pipe body can be rotated, and the ring will drive the connecting pipe connected to the docking port to rotate, rotate the connecting pipe to the required connection direction, and make the connecting port correspond to the docking port, insert the connecting pipe into the connecting port, and connect the connecting port to the connecting pipe through the limiting device, so that the connecting pipe can be connected to water pipes in different directions, which meets the use requirements in more situations and has a wider range of applications.

[0009] The utility model is further configured as follows: the limiting mechanism includes a cavity arranged in the connecting pipe and a driving rod slidably connected to the cavity, an elastic member is arranged between the driving rod and the inner wall of the cavity, one end of the driving rod away from the pipe body is fixedly connected to a pressing rod, a through hole 1 for the pressing rod to extend out is arranged on the inner wall of the cavity, the other end of the driving rod is fixedly connected to a limiting block, a through hole 2 for the limiting block to extend out is arranged on the inner wall of the cavity, and a limiting groove for the limiting block to be inserted into is arranged on the inner wall of the connecting port.

[0010] By adopting the above technical solution, when the docking interface is rotated to correspond to the position of the connecting port, the pressing rod is pressed, and the pressing rod will drive the driving rod to approach the axis of the connecting pipe. At this time, the elastic member will contract, and the driving rod can drive the limiting block to retract into the cavity through the second through hole, and the end of the connecting pipe can be smoothly inserted into the connecting port from the docking interface. When the pressing block is inserted into the outer wall of the sleeve, the second through hole just corresponds to the position of the limiting groove. At this time, the pressing rod is released, and the driving rod can return to its original position through the rebound force of the elastic member, and can drive the limiting block to extend out of the second through hole and be stuck in the limiting groove. At this time, the connecting pipe can no longer be pulled out, and the connecting pipe can be connected to the connecting port in this direction to realize the water pipe connection in this direction. When the connecting pipe needs to be pulled out, the pressing rod is pressed again to pull the limiting block out of the limiting groove.

[0011] The utility model is further configured as follows: a fixing ring is sleeved on the outer wall of the pipeline body, a moving block is fixedly connected to the sleeve ring, and a moving groove is provided on the fixing ring for the moving block to be inserted and moved.

[0012] By adopting the above technical solution, when the collar rotates, the moving block will be inserted into the moving groove to move, so that the rotation of the collar is more stable.

[0013] The utility model is further configured as follows: the moving block is arranged in a trapezoidal shape, and the shape of the moving groove is consistent with the moving block.

[0014] By adopting the above technical solution, the moving block and the moving groove are both arranged in a trapezoidal shape, which can prevent the moving block from falling off from the moving groove during the rotation process, and further enhance the stability of the ring rotation.

[0015] The utility model is further configured as follows: the inner wall of the moving groove is provided with a plurality of array-distributed universal balls, and the universal balls are fitted with the surface of the moving block.

[0016] By adopting the above technical solution, when the moving block moves along the annular track of the moving ring, the universal ball will roll along the surface of the moving block, reducing the friction between the moving block and the moving groove, making the rotation of the ring smoother.

[0017] The utility model is further configured as follows: a sealing strip arranged in an annular shape is fixedly connected to the outer wall of the pipeline body, and a sealing groove for the sealing strip to be embedded is arranged on the inner wall of the collar.

[0018] By adopting the above technical solution, during the rotation of the ring, the sealing strip is always inserted into the sealing groove, thereby reducing the liquid leakage from the gap and enhancing the sealing performance of the connector.

[0019] The utility model is further configured as follows: a protrusion is fixedly connected to the inner wall of the docking port, and a concave groove for the protrusion to be inserted and moved is arranged on the outer wall of the connecting pipe.

[0020] By adopting the above technical solution, after the protrusion is inserted into the recessed groove, it can prevent the connecting pipe from falling off from the docking port during horizontal movement, so that the positions of the limit block and the limit groove can always correspond to each other on the same straight line.

[0021] In summary, the utility model has the following beneficial effects:

[0022] The utility model drives the connecting pipe to rotate to correspond to the connecting ports in different directions by arranging a rotatable sleeve ring, so that the connecting pipe can be connected to pipes in different directions, and is suitable for use in more situations.

[0032] When the collar 3 is rotated until the docking port 4 corresponds to the connecting port 2 , the connecting pipe 5 is inserted into the connecting port 2 , and a limiting mechanism is provided between the connecting pipe 5 and the connecting port 2 .

[0033] The limiting mechanism includes a cavity 6 arranged in the connecting pipe 5 and a driving rod 7 slidably connected to the cavity 6.
