Description

Technical Field

[0001] The utility model relates to the field of docking devices, and more particularly to a docking device used for a reverse osmosis water treatment pipe mouth. Background Art

[0002] Reverse osmosis is a membrane separation technology that uses pressure as the driving force by virtue of the function of selective permeable (semi-permeable) membranes. Pipe butt connection refers to heating and softening two pipe ends through a PPR hot melt machine, and then using the two pipe ends to respectively cover the two ends of a connecting pipe. After the pipe ends cool down, a higher air tightness can be achieved, thereby completing the pipe butt connection. The connecting pipe used in the existing pipe butt connection needs to be covered on the outer wall of the pipe end. After one end of the connecting pipe is covered on the outer wall of one of the pipe ends, the two pipe ends need to be moved away from each other so that the other end of the connecting pipe is aligned with the other pipe end, and then approach each other and cover. In an environment where the length is fixed, using only one connecting pipe to connect the pipe ends will make it difficult for the two pipe ends to move away from each other, making it difficult for the two ends of the connecting pipe to be respectively covered on the outside of the two pipe ends.

[0003] The utility model with authorization announcement number CN220351813U discloses a reverse osmosis water treatment pipe nozzle docking mechanism, which relates to the field of reverse osmosis technology, including a No. 1 pipe nozzle and a No. 2 pipe nozzle, the outer sides of the No. 1 pipe nozzle and the No. 2 pipe nozzle are both sleeved with a thermoplastic pipe, and a convex thread is welded on the outer side of the thermoplastic pipe near the middle position. A positioning pipe is provided on the outer side of the two thermoplastic pipes, and a connecting pipe is provided on the inner side of the two positioning pipes. One end of the two connecting pipes is respectively in contact with one end of the two thermoplastic pipes. In the utility model, through the setting of the pipe sleeve structure, one end of the two thermoplastic pipes can be heated and sleeved on the outer sides of the No. 1 pipe nozzle and the No. 2 pipe nozzle respectively, and then the two ends of the two connecting pipes in contact with each other are respectively aligned with one end of the two thermoplastic pipes, and then the positioning pipe is slid to the outer side of the thermoplastic pipe and fixed by the cooperation of the convex thread and the thread groove, so that the interior of the No. 1 pipe nozzle and the No. 2 pipe nozzle are directly connected without moving the No. 1 pipe nozzle and the No. 2 pipe nozzle.

[0004] In the above-mentioned disclosed structure, the positioning tube and the connecting tube are combined to install the pipe mouth, which can be threadedly installed and positioned, but the spacing between the connected pipe mouths is relatively fixed, which is not conducive to placing them between the two pipe mouths and is prone to interference. Moreover, the length cannot be adjusted after threaded installation, which easily affects the connection stability due to the length and is not conducive to docking installation. This needs to be improved. Utility Model Content
