The pipeline locking device can be applied to locking and fixing the sewer pipe 8 and the drain pipe 9, but is not limited to the device. In this case, the drain pipe 8 constitutes the one of the pipes, and the drain pipe 9 constitutes the other pipe.
The working principle of the invention is described below by taking the application to a sewer pipe 8 and a drain pipe 9 as examples: firstly, sleeving the device outside a sewer pipe 8, inserting the lower end of the sewer pipe 8 into the upper end of a drain pipe 9, and moving the whole device downwards to the outside of the upper end of the drain pipe 9, wherein the other shell 2 is arranged above one of the shells 1; then, when each of the turnbuckle clamping blocks 22 of the other shell 2 is aligned with the inlet and outlet grooves 121 of the turnbuckle groove 12 of one shell 1, one of the shells 1 is supported by one hand, the other shell 2 is pressed down by the other hand, and the two holding pieces 3 are pressed down by the other shell 2 to move downwards along the guide inclined plane 11, so that the two holding pieces 3 are mutually close to each other to shrink, and simultaneously the first elastic piece 4 and the second elastic piece 5 are compressed; then, the other housing 2 is rotated clockwise by a certain angle (the angle is about 50 °), so that the two housings complete the turnbuckle connection, and in the rotation process of the other housing 2, the two clasping members 3 are driven to rotate together. The two enclasping pieces 3 are mutually closed and contracted to enclasp the drain pipe 9, so that the whole device is positioned on the drain pipe 9, and meanwhile, the other shell 2 limits the rubber plug 7 sleeved at the lower end of the drain pipe 8 to be separated from the drain pipe 9, so that the lower end of the drain pipe 8 is firmly limited in the drain pipe 9, as shown in fig. 8 and 9. Thus, the present invention can prevent the drain pipe 8 from being accidentally separated from the drain pipe 9.
When the sewer pipe 8 is required to be pulled out from the drain pipe 9, the other shell 2 is rotated clockwise for a certain angle, so that the turnbuckle clamping blocks 22 of the other shell 2 are respectively retracted to the inlet and outlet grooves 121 of the turnbuckle grooves 12 of one shell 1, at the moment, the first elastic piece 4 is reset to push the holding pieces 3 to move upwards along the guide inclined plane 11, the other shell 2 is synchronously jacked upwards, and at the same time, the second elastic piece 5 is reset to jack the two holding pieces 3, so that the two holding pieces 3 are mutually separated to release the drain pipe 9, as shown in fig. 10 and 11. Therefore, the whole device is not positioned on the drain pipe 9 any more, and a user can easily pull the lower end of the drain pipe 8 upwards out of the drain pipe 9.
Referring to fig. 1-12, a drainage device of the present invention includes a drainage pipe 8 and a drainage pipe 9, and further includes a pipe locking device of the present invention as described above, wherein the drainage pipe 8 forms one pipe, and the drainage pipe 9 forms the other pipe.
