Wherein, by adopting multiple sealing ribs arranged at intervals, the sealing ribs are annular protrusions surrounding the joint body, and the protrusion heights of the multiple sealing ribs increase sequentially from the port of the joint body to its tail. The structure makes it easier for the pipeline to slide from the joint body to the side end surface of the positioning plate, and improves the sealing performance.

And when the operation tool is pressed, the required operation force is small, which is convenient for operation. Moreover, when the pipeline is fully pressed in place, the end surface of the pipeline deformed due to the difference in resistance between the inside and outside of the axial direction is a tapered surface. The surface is attached to the side end surface of the positioning plate to form a double-enhanced end face sealing effect, which further strengthens the sealing performance of the connection, thereby improving the sealing performance when connecting with the pipeline. At the same time, the reinforced water-locking sealing ring on the side of the positioning plate facing the port makes the joint and the port connected to the pipeline more closely fit together. After being pressed and connected by the sliding sleeve, it has a stronger water-locking function to prevent The port is leaking.

In order to make the purpose, technical solutions and advantages of the embodiments of the utility model more clear, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described The embodiments are some embodiments of the present utility model, but not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to FIG. 1 . FIG. 1 is a schematic structural diagram of a sliding-tight pipeline connection joint provided by an embodiment of the present invention.

The sliding-tight pipeline connection joint provided by the embodiment of the utility model includes a joint body 1, the tail of the joint body 1 is provided with a positioning plate 4, and the joint body 1 has multiple sealing ribs 2 arranged at intervals, and the sealing rib 2 is a surrounding The ring-shaped protrusion of the joint body 1, the height of the protrusions of the multi-channel sealing rib 2 increases sequentially from the port of the joint body 1 to its tail, and the side of the positioning plate 4 facing the port, that is, the side end surface 6 of the positioning plate 4 is provided with a reinforced water-locking The sealing ring 3, the reinforced water-locking sealing ring 3 is annularly arranged on the joint body 1, and the surface of the reinforced water-locking sealing ring 3 is an annular rectangular surface or a conical surface. Among them, by adopting multiple sealing ribs 2 arranged at intervals, the sealing ribs 2 are annular protrusions surrounding the joint body 1, and the height of the protrusions of the multi-channel sealing ribs 2 increases sequentially from the port of the joint body 1 to its tail, so that It is easier for the pipeline 8 to slide from the joint body 1 to the side end surface 6 of the positioning plate 4, and the sealing performance is improved. Taking the four sealing ribs 2 as an example, they are respectively the first sealing ribs arranged from the port of the joint body 1, The second sealing rib, the third sealing rib and the fourth sealing rib, the raised height of the first sealing rib is lower than the raised height of the second sealing rib, the raised height of the second sealing rib is lower than the raised height of the third sealing rib The raised height of the third sealing rib is lower than the raised height of the fourth sealing rib, so when the pipeline 8 is plugged in from the port of the joint body 1, it passes through the first sealing rib, the second sealing rib, the The third sealing rib and the fourth sealing rib reach the side end surface 6 of the positioning plate 4 after exceeding the fourth sealing rib, which can effectively prevent the pipeline from being pressed against the side end surface 6 of the positioning plate 4 by fixing devices such as the sliding sleeve 7 There is a gap between the end face of 8 and the side end face 6 of the positioning plate 4, resulting in the hidden danger of water leakage. Moreover, since the raised height of the first sealing rib and the second sealing rib is low, the damage to the compressive strength of the pipeline 8 by the sealing rib 2 can be effectively weakened, and the drawing resistance and temperature resistance of the connecting joint between the pipeline 8 and the pipe fitting can be effectively improved.
