[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0025] Example 1, by Figure 1 The present invention relates to a quick-connect valve for pipelines with a self-locking sealing structure, comprising a valve body 1, a connection port 4 on the valve body 1, a pipeline 3 on the outside of the connection port 4, and a connection mechanism 2 between the pipeline 3 and the connection port 4.
[0026] Specifically, by Figure 2-5The connecting mechanism 2 includes a connecting pipe 201 fixed to one end of the pipe 3 near the connection port 4. A connecting pipe 207 is fixedly connected to the end of the connection port 4 near the pipe 3. A notch 208 is provided on the connecting pipe 207, and a rubber pad 209 is fixedly installed on the inner side of the notch 208. The connecting pipe 201 is threadedly connected to the notch 208, and the connecting pipe 201 fits against the rubber pad 209. Two U-shaped round rods 203 are symmetrically fixedly connected to the outer side of the connecting pipe 201. A sliding plate 204 is movably sleeved on the outer side of each of the two U-shaped round rods 203. The two sliding plates 204 are connected to each other. An arc-shaped plate 202 is fixedly connected to each other on the adjacent side. Two positioning rods 2012 are symmetrically fixedly connected inside each of the two arc-shaped plates 202. Two positioning rings 205 are symmetrically fixedly connected to the outer sides of connecting pipe one 201 and connecting pipe two 207. Each positioning rod 2012 is inserted into its respective positioning ring 205. A limiting plate 2018 is fixedly connected to the outer side of the sliding plate 204. The limiting plate 2018 is movably sleeved on the outer side of the U-shaped round rod 203. When the sliding plate 204 slides along the U-shaped round rod 203, it causes the limiting plate 2018 to slide along the U-shaped round rod 203. To ensure the stability of the sliding plate 204 during movement, an outer cylinder 2015 is threaded onto the outer side of the connecting pipe 201. Two limiting rings 2021 are symmetrically fixedly connected to the outer side of the outer cylinder 2015. A movable ring 2016 is provided between the two limiting rings 2021. Two connecting posts 2017 are symmetrically fixedly connected to the outer side of the movable ring 2016. A slider 2014 is fixedly connected to the end of each connecting post 2017 away from the movable ring 2016. The two sliders 2014 are respectively sleeved on the outer sides of the two U-shaped round rods 203. The sides of the two sliders 2014 that are close to each other are rotatably connected. Two movable rods 2013 are connected to each other. The ends of the two movable rods 2013 that are close to each other are rotatably connected to two sliding plates 204. Rubber ring 2011 and two rubber rings 2010 are fixedly connected to the sides of the two arc plates 202 that are close to each other. Rubber ring 2011 is located between the two rubber rings 2010. Outer rings 206 are fixedly sleeved on the outside of connecting pipe 1 201 and connecting pipe 2 207. Rubber ring 2011 is located between the two outer rings 206 and fits against connecting pipe 1 201 and connecting pipe 2 207. Rubber ring 1 2010 fits against outer ring 206.
[0027] In use, first thread the connecting pipe 201 onto the notch 208 until it is in contact with the rubber pad 209. Then connect the connecting pipe 201 to the connecting pipe 207. Next, rotate the outer cylinder 2015 outside the connecting pipe 201. This pushes the movable ring 2016 through the two limiting rings 2021, and drives the two sliders 2014 to slide along the two U-shaped rods 203 through the two connecting posts 2017. Finally, the two movable rods 2013 drive the two sliding plates 204 to slide along the two U-shaped rods 203. The round rod 203 slides, while the two arc plates 202 move closer to each other until they fit together. Meanwhile, each positioning rod 2012 is inserted into each positioning ring 205, reconnecting the first connecting pipe 201 and the second connecting pipe 207, thus firmly fixing the pipe 3 to the connection port 4 and enabling the rapid installation of the pipe 3. At the same time, the second rubber ring 2011 is located between the two outer rings 206 and fits together with the first connecting pipe 201 and the second connecting pipe 207, while the first rubber ring 2010 fits together with the outer ring 206, finally ensuring the sealing between the pipe 3 and the connection port 4.
[0028] Specifically, by Figure 6 As shown, two limiting rings 2021 are fixedly connected at equal angles to one side of each other, and one end of each side rod 2019 is provided with a ball 2020 that abuts against the movable ring 2016.
[0029] In use, the movable ring 2016 is located outside the outer cylinder 2015 and does not contact the outer cylinder 2015. When the outer cylinder 2015 rotates and moves, the movable ring 2016 is pushed by each ball 2020 to prevent the outer cylinder 2015 and the limit ring 2021 from directly contacting the movable ring 2016, thus ensuring that the movable ring 2016 can move smoothly.
