Description

Technical Field

[0001] The present application relates to the technical field of pipeline connectors, and particularly to a claw pipe joint with a rotatable head. Background Art

[0002] A claw pipe joint is a kind of pipe joint that uses a claw structure to cooperate with a corresponding flange to connect and fix a male head and a female head. For traditional claw pipe joints, the two connected pipes need to rotate relative to each other. In working conditions where the pipes cannot rotate, it is difficult to meet the pipeline connection requirements; traditional pipe joints can meet the pipeline connection requirements to a certain extent, but during pipeline docking, the operation is relatively cumbersome and often requires reconnection, affecting work efficiency. Utility Model Content

[0003] In order to improve the cumbersome operation during pipeline docking, which affects work efficiency and is not convenient for adjusting the claws, the present application provides a claw pipe joint with a rotatable head.

[0004] The claw pipe joint with a rotatable head provided by the present application adopts the following technical solutions:

[0005] A claw pipe joint with a rotatable head includes a main pipeline, claws, and a limiting member; the main pipeline has a clamping portion and a rotating portion; the claws are rotatably arranged on the rotating portion; the limiting member is installed on the clamping portion and is used to cooperate with the main pipeline to clamp the claws.

[0006] By adopting the above technical solutions, the claw part of the claw pipe joint is independently sleeved on the main pipeline. When connecting two pipe joints, only the claw part needs to be rotated, and there is no need to rotate the main pipeline, which is convenient to use and meets the connection of two independent pipelines in the working condition where the pipeline cannot rotate, improving the applicability of pipeline installation under different working conditions. The claw part rotates along the main pipeline, and the limiting member is used to limit and fasten the claws and the main pipeline.

[0007] Optionally, the limiting member includes a limiting sleeve and a rubber snap ring. The limiting sleeve is rotatably sleeved on the main pipeline, and the limiting sleeve is snap-fitted with the claws. A groove is formed on the main pipeline, and the rubber snap ring is snap-fitted in the groove.

[0008] By adopting the above technical solutions, the limiting sleeve is installed axially on the main pipeline to support the claw part, and the rubber snap ring is used to fix the axial positions of the claws and the limiting sleeve.

[0009] Optionally, an avoidance groove is formed on the outer wall of the main pipeline, and the end of the claw is movably arranged in the avoidance groove.

[0010] By adopting the above technical solution, the claw located in the avoidance groove has sufficient space for rotation during rotation, reduces the contact area with the main pipeline, reduces the frictional resistance, and facilitates the rotation and adjustment of the claw.

[0011] Optionally, the limiting sleeve is formed with a first clamping surface, and the claw is formed with a second clamping surface, and the first clamping surface and the second clamping surface are mutually attached.

[0012] By adopting the above technical solution, both the first clamping surface and the second clamping surface are stepped, and they just fit together after being attached. The two clamping surfaces after fitting improve the sealing performance between the limiting sleeve and the claw.

[0013] Optionally, a groove is opened at the end of the main pipeline, and a sealing ring is clamped in the groove.

[0014] By adopting the above technical solution, the sealing ring arranged in the groove is used to improve the sealing performance of the connection between the two pipelines.

[0015] Optionally, the avoidance groove is annularly arranged, and the height of the avoidance groove is less than the height of the limiting sleeve.

[0016] By adopting the above technical solution, the annular arrangement makes it convenient for multiple claws located on the main pipeline to rotate in the avoidance groove, and the limiting sleeve forms a surrounding space for the avoidance groove to prevent the rotation angle of the claw from being too large.

[0017] Optionally, the rotation angle formed by the axis of the main pipeline and the claw is 0 to 15°.

[0018] By adopting the above technical solution, the deflection angle of the claw is within 15 degrees, so that the claw rotates slightly, which is convenient for opening a certain angle to dock the two pipelines.

[0019] Optionally, the rubber snap ring abuts against the end face of the limiting sleeve away from the claw.

[0020] By adopting the above technical solution, the bottom of the limiting sleeve is tightly pressed by the rubber snap ring to fix the axial positions of the claw and the limiting sleeve, ensure that the clamping end face of the claw is parallel to the axis of the main pipeline, and make the two independent pipelines after connection coaxial.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. For the rotating part on the main pipeline, the claw rotates along the rotating part, and the connection of the two pipeline joints is realized under the condition of non-rotating pipelines. The claw is limited and fastened by the limiting part, so that it is applicable to more installation working condition scenarios and facilitates installation and use;

[0023] 2. A relief groove is provided between the limiting member and the main pipe, so that the contact area between the clamping jaw and the main pipe is reduced during rotation, the frictional resistance is lowered, and it is convenient to rotate and adjust the clamping jaw.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following will further elaborate on the present application in conjunction with the Figures 1-4 drawings.

[0031] Embodiment 1

[0032] The embodiment of the present application discloses a clamping jaw pipe joint with a rotatable head.

[0033] Refer to Figure 1, including a main pipe 1, a claw 2 and a limiting member 3; the main pipe 1 has a clamping portion 11 and a rotating portion 12; the claw 2 is rotatably arranged on the rotating portion 12, and in the embodiment, three claws 2 are provided; the limiting member 3 is installed on the clamping portion 11 and is used to cooperate with the main pipe 1 to clamp the claw 2. The claw 2 on the main pipe 1 rotates by relying on the rotating portion 12. After the pipes are butted, the rotating claw 2 part abuts against the outer wall of the pipe; in the working condition of pipe butting, when two independent pipes can both rotate independently, the claw 2 pipe joint can rotate and install and fasten the pipes on both sides; when two independent pipes can only make one of the pipes rotate, the clamping portion of the claw 2 pipe joint faces the rotatable pipe. After the rotatable pipe and the limited pipe are butted and fastened, the limiting member 3 further fastens the two connected pipes, realizing the connection of pipes under different working conditions and improving the applicability of pipe connection.

[0034] See Figure 2 As shown, the limiting member 3 includes a limiting sleeve 31 and a rubber snap ring 32. The limiting sleeve 31 is rotatably sleeved on the main pipe 1. The limiting sleeve 31 is in snap-fit with the claw 2. A groove 33 is formed on the main pipe 1. The rubber snap ring 32 is snap-fitted in the groove 33. The rubber snap ring 32 abuts against the end face of the limiting sleeve 31 away from the claw 2. The axial setting of the limiting sleeve 31 on the main pipe 1 plays a supporting role for the claw 2, and the axial positions of the claw 2 and the limiting sleeve 31 are fixed by using the rubber snap ring 32.

[0035] See Figure 2 As shown, an embedding groove 5 is formed at the end of the main pipe 1, and a sealing ring 6 is snap-fitted in the embedding groove 5. The sealing ring 6 arranged in the embedding groove 5 improves the sealing performance of the pipe connection.

[0036] The implementation principle of a claw pipe joint with a rotating head in the embodiment of the present application is as follows: the claw 2 part of the claw 2 pipe joint is independently sleeved on the main pipe 1. When connecting two pipe joints, only the claw 2 part needs to be rotated for installation, and the main pipe 1 does not need to be rotated, meeting the installation scenario under the working condition that the pipe cannot rotate, making the pipe butting more convenient, reducing the workload and improving the work efficiency.

[0037] Embodiment Two

[0038] See Figure 3 and Figure 4 As shown, based on the structure of Embodiment One, an avoidance groove 4 is formed on the outer wall of the main pipe 1. The end of the claw 2 is movably arranged in the avoidance groove 4. The height of the avoidance groove 4 is less than the height of the limiting sleeve 31. The avoidance groove 4 is formed on the contact surface where the main pipe 1 is in contact with the claw 2 and the limiting sleeve 31, and the avoidance groove 4 is annularly arranged, so that the rotation angle formed by the axis of the main pipe 1 and the claw 2 is 0-15°. This facilitates the rotation of the end of the claw 2 located in the avoidance groove 4, reduces the contact area between the claw 2 and the main pipe 1, reduces the frictional resistance, and facilitates the rotation and adjustment of the claw 2.

[0039] See Figure 4 As shown, the limit sleeve 31 is formed with a first clamping surface 313, and the clamping jaw 2 is formed with a second clamping surface 314. The first clamping surface 313 and the second clamping surface 314 are mutually attached. Both the first clamping surface 313 and the second clamping surface 314 are stepped surfaces. After the first clamping surface 313 and the second clamping surface 314 are mutually attached, they just fit together, which is convenient for keeping the end face of the clamping jaw 2 parallel to the axis of the main pipe 1, and the clamping part of the clamping jaw 2 effectively presses against the outer pipe wall of the other installed pipe, ensuring the sealing performance after the two pipes are connected.

[0040] The implementation principle of a claw pipe joint with a rotating head in an embodiment of the present application is as follows: The provided avoidance groove 4 reduces the contact area between the clamping jaw 2 and the main pipe 1 during the rotation of the clamping jaw 2, reduces the frictional resistance, and facilitates the rotation and adjustment of the clamping jaw 2, realizing the docking of two pipes under the condition that the pipes cannot rotate.
