Detailed Description

As shown in fig. 1 to 6, a pipe connection structure comprises a first outer pipe 10 and a second outer pipe 20, wherein a first joint 30, a limit key 40 and a sliding key 50 are disposed in the first outer pipe 10, the first joint 30 is disposed at the bottom of the limit key 40, one side of the sliding key 50 is connected with the limit key 40, the other side extends to the outside of the first outer pipe 10, a second joint 60 is disposed at the end of the second outer pipe 20, the second joint 60 passes through the first joint 30 and pushes the limit key 40 to move upwards, at this moment, the second outer pipe 20 is rotated to drive the second joint 60 to rotate, the end of the second joint 60 is engaged with the top wall 33 of the first joint 30, the bottom of the limit key 40 is engaged between the second joint 60 and the first joint 30 to prevent the second joint 60 from rotating out of the first joint 30, so that the connection between the first outer pipe 10 and the second outer pipe 20 is completed, and when the first outer pipe 10 and the second outer pipe 20 are disassembled, the sliding key 50 on the surface of the first outer pipe 10 is pushed to move upwards to drive the sliding key 50 to move the second joint 40 to drive the second joint 60 out of the second joint 30 to rotate, and the second joint 60 is then disengaged from the corresponding joint 30, and the second joint 30 is rotated to drive the second joint 30.

In order to make the connection between the first outer tube 10 and the second outer tube 20 more stable, the end portion of the second joint 60 is provided with a connecting column 61 and a clamping portion 62, the edge of the hole site 31 of the top wall of the first joint 30 is provided with a plurality of limiting walls 32, the surface of the limiting key 40 facing the first joint 30 is provided with a plurality of clamping walls 41, when the first outer tube 10 and the second outer tube 20 are connected, the clamping portion 62 of the second joint 60 passes through the surface of the top wall of the first joint 30, the connecting column 61 is arranged in the hole site 31, the second joint 60 is rotated to enable the edge of the clamping portion 62 and the hole site 31 to be clamped and connected until the edge of one side of the clamping portion 62 is abutted to the limiting walls 32 to stop rotating, at this time, the limiting key 40 is pushed to move towards the first joint 30 until the clamping walls 41 are clamped in the gap between the other side of the clamping portion 62 and the limiting walls 32, and the non-rotatable connection structure of the second joint 60 clamped in the first joint 30 is more stable.
