[0019] The technical scheme in the utility model embodiment will be described clearly and completely in combination with the drawings in the utility model embodiment.
[0020] In order to avoid impurities and dust from entering the steel nylon composite pipeline 1, reference Figure 1 、 Figure 2 and Figure 3As shown, the device includes a connector 2 installed at the opening of a steel-nylon composite pipe 1. The connector 2 has a sealing cavity 3 for inserting the steel-nylon composite pipe 1. A sealing sleeve 4 is arranged around the opening of the sealing cavity 3. Limiting components for positioning the steel-nylon composite pipe 1 after insertion are provided on both sides of the connector 2. The operator uses the handheld part 11 to align the connector 2 with the insertion direction to the side of the steel-nylon composite pipe 1 where sealing is required. As the steel-nylon composite pipe 1 is inserted into the sealing cavity 3 within the connector 2, the sealing sleeve 4 is... The compression of the outer wall of the steel-nylon composite pipe 1 will cause it to deflect towards the inner side of the sealing cavity 3 and abut against the outer wall of the steel-nylon composite pipe 1, forming an independent sealing cavity 3, which has a sealing effect on the steel-nylon composite pipe 1. When the steel-nylon composite pipe 1 is inserted into the sealing cavity 3, the flange 7 will be inserted into the groove 8 opened in the clamping joint 6, so that the flange 7 abuts against the limiting plate 9. Under the elastic force of the return spring 10, the limiting plate 9 limits and fixes the flange 7, ensuring the stability of the joint 2 after installation.
[0021] To facilitate improving the stability of connector 2 after installation, refer to... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the limiting component includes two ears 5 disposed on the back side of the connector 2. Both ears 5 have outwardly expanding clamping connectors 6 integrally formed facing both sides of the connector 2. The ears 5 facilitate the removal of the connecting head 2 later. Workers can pull the ears 5 up and down to disengage the flange 7 from the groove 8 within the clamping connector 6, thus removing the connector 2. The steel-nylon composite pipe 1 has a flange 7 fitted onto the outer side of one end facing the connector 2. The flange 7 is inserted into the groove 8 and abuts against the limiting plate 9, thereby fixing the connecting head 2 and preventing the connector 2 from easily detaching. The clamping connector 6 has a groove 8, and an elastic element is connected to the inner wall of the groove 8. The other end of the elastic element is connected to the limiting plate 9, which abuts against the flange 7. The elastic element is a return spring 10. When the flange 7 is inserted into the groove 8, the outer wall of the flange abuts against the limiting plate 9 and pushes the limiting plate 9. As the return spring 10 is compressed, the elastic force reacts on the limiting plate 9, fixing the flange 7 and further fixing the entire joint 2 to the steel-nylon composite pipe 1, improving the stability of the joint 2 after installation. The elastic element can also be a tension spring, and a spring connecting plate is provided at the connection between the return spring 10 and the inner wall of the groove 8. This is existing technology and will not be described in detail here. Two handles 11 are provided around the outer side of the joint 2. The two handles 11 are symmetrically arranged to facilitate the installation or removal of the joint 2. The sealing sleeve 4 is made of rubber, and its opening diameter is smaller than that of the steel-nylon composite pipe 1. Therefore, when the steel-nylon composite pipe 1 is inserted into the sealing cavity 3, it will squeeze the opening of the sealing sleeve 4 around, causing the sealing sleeve 4 to engage with the steel-nylon composite pipe 1, forming a sealing effect. The diameter of the sealing cavity 3 is compatible with the diameter of the steel-nylon composite pipe 1.
[0022] In use, firstly, align the insertion direction of the connector 2 with the side of the steel-nylon composite pipe 1 that needs to be sealed using the handheld part 11. As the steel-nylon composite pipe 1 is inserted into the sealing cavity 3 inside the connector 2, the sealing sleeve 4 is squeezed by the outer wall of the steel-nylon composite pipe 1 and will deflect towards the inside of the sealing cavity 3, and abut against the outer wall of the steel-nylon composite pipe 1 to form an independent sealing cavity 3, which has a sealing effect on the steel-nylon composite pipe 1. After the steel-nylon composite pipe 1 is inserted into the sealing cavity 3, the flange 7 will be inserted into the groove 8 opened in the snap connector 6, so that the flange 7 abuts against the limiting plate 9. Under the elastic force of the return spring 10, the limiting plate 9 limits and fixes the flange 7.
[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
