[0022] Embodiment:

[0023] As Figures 1 to 4 shown, the present utility model provides a quick-change joint for pipeline pressure testing, including a connecting pipe 1. A fixing seat 4 is provided on one side of the connecting pipe 1. Before using the joint, the user can fix the joint at a specified position through its fixing seat 4, which can effectively increase the stability of the joint during pressure testing, thereby effectively reducing the intensity of its vibration, effectively prolonging the service life of the joint and the seal, and improving the reliability and durability of the joint.

[0024] An upper fixing clip 2 is provided above the connecting pipe 1, and a lower fixing clip 3 is provided below it. A plurality of positioning blocks 17 are provided on one side of the lower fixing clip 3. The lower fixing clip 3 is connected to the upper fixing clip 2 through the plurality of positioning blocks 17. This structure effectively reduces the time required for installation, and through this connection method, it can effectively prevent the lower fixing clip 3 and the upper fixing clip 2 from loosening or displacing during use.

[0025] The connecting pipe 1 is clamped between the upper fixing clip 2 and the lower fixing clip 3. A plurality of limiting blocks 8 are provided on the circumferential side of the connecting pipe 1. A plurality of limiting grooves 9 are opened on the inner side surfaces of the upper fixing clip 2 and the lower fixing clip 3. The plurality of limiting blocks 8 are respectively clamped in the plurality of limiting grooves 9. Through its limiting blocks 8 and limiting grooves 9, the accuracy and stability of the position of the connecting pipe 1 after installation are ensured, preventing it from moving or being misaligned during use, and this structure can withstand the vibration and pressure that the pipeline system may face during operation, thereby maintaining the stability and reliability of the connection.

[0026] On one side of the upper fixing clip 2 and the lower fixing clip 3, there are fixing blocks 7. There is a sleeve 5 on the fixing seat 4, and a screw rod 6 is arranged inside the sleeve 5. Both groups of fixing blocks 7 are clamped in the sleeve 5, and the screw rod 6 is threadedly connected to both groups of fixing blocks 7. The upper fixing clip 2 and the lower fixing clip 3 are firmly fixed together by means of threaded connection. This ensures the stability of the connection, can effectively resist the influence of vibration and external forces, and through this connection structure, it is also convenient for the user to adjust the spacing and fixing force of the joint.

[0027] As Figures 2 to 4 shown, both ends of the connecting pipe 1 are provided with a plurality of movable clips 12. The plurality of movable clips 12 are respectively located inside both ends of the connecting pipe 1. After the user inserts the pipeline into the connecting pipe 1, the user can fix the pipeline through the movable clips 12. Fixing the pipeline through a plurality of movable clips 12 can effectively reduce the vibration and accidental movement of the pipeline during use, and ensure the stability and safety of the system operation.

[0028] Both sides of the connecting pipe 1 are provided with a plurality of cylinders 11. The connecting pipe 1 is provided with a plurality of mounting seats 10, and a placing groove 14 is opened on each of the plurality of mounting seats 10.

The user can adjust the movable clips 12 through the cylinders 11 according to the size of the pipeline. Precise adjustment of the movable clips 12 can be achieved through the cylinders 11. This precision makes the installation process more convenient, can ensure the accurate docking and fixing of the pipeline, and through the cylinders 11, a reliable fixing force can also be provided for the pipeline, which can effectively prevent the pipeline from accidentally moving or vibrating during use.

[0029] A plurality of baffles 15 are arranged inside the connecting pipe 1. A sealing ring 13 is directly provided between each of the plurality of baffles 15 and each of the plurality of movable clips 12. Mounting grooves 18 are opened on the corresponding sides of the plurality of baffles 15. One ends of the plurality of movable clips 12 are provided with clamping grooves 16. One ends of the plurality of sealing rings 13 are respectively clamped in the plurality of mounting grooves 18, and the other ends are respectively clamped in the plurality of clamping grooves 16. After the user fixes the pipeline, the sealing ring 13 will be wrapped in the mounting groove 18 and the clamping groove 16. This enables the sealing ring 13 to effectively block the gap between the baffle 15 and the movable clip 12, which can effectively prevent liquid or gas from leaking out from the connection during the pressure test, and effectively ensure the accuracy of the test data.

[0030] The specific usage method and function of this embodiment:

[0031] Before using the connector, the user can fix the connector at its designated position through its fixing base 4. This structure can effectively increase the stability of the connector during the pressure test and effectively reduce the intensity of its vibration. Moreover, the user can also adjust the spacing and fixing force of the connector by rotating the fixing base 4, which effectively increases the applicable range of the connector. After the adjustment is completed, the user can insert the pipeline into the connecting pipe, and then the user can adjust the movable clamp 12 through the cylinder 11 according to the size of the pipeline. The cylinder 11 can achieve precise adjustment of the movable clamp 12. This precision makes the installation process more convenient, can ensure the accurate docking and fixing of the pipeline, and the cylinder 11 can also provide a reliable fixing force for the pipeline, which can effectively prevent the pipeline from accidentally moving or vibrating during use.
