[0022] Among them, the fitting assembly 108 is located on one side of the fastening assembly 107, the fastening assembly 107 is located on one end of the screw rod 103, each of the abutting assemblies 106 is located on one side of the corresponding flange plate 101, the locking cap 105 is located on the circumferential side of the screw rod 103, the nut 104 is located on one end of the screw rod 103, the screw rod 103 is located on the circumferential side of the corresponding flange plate 101, the installation of the fastening cap 111 is directly fastened by rotating, the installation process is convenient and fast, and since the lead screw 113 in the fastening cap 111 is also threadedly connected with the screw rod 103, the fastening cap 111 is not easily slipped off after being installed on the screw rod 103, and the vibration after the pipeline connection will not cause the fastening cap 111 to fall off.

[0023] Second, the second gasket 110 is located on one side of one of the flange plates 101, the first gasket 109 is located on one side of the other flange plate 101, each of the convex strips 112 is located on the circumferential side of the fastening cap 111, the fastening cap 111 is located on one end of the screw rod 103, the first gasket 109 and the second gasket 110 are installed after the screw rod 103 is inserted and connected to two disc bodies 115, which buffers and dampens the inner side of the nut 104 and the inner side of the locking cap 105, after the locking cap 105 is rotated and stabilized on the outer end of the screw rod 103, the fastening cap 111 is rotated and connected to the outer end of the screw rod 103, the length of the fastening cap 111 and the length of the fitting ring 114 are added to be the same as the length of the screw rod 103 exposed on the outer end of the locking cap 105, so that after the fastening cap 111 is rotated and connected, there is no exposed screw rod 103, which resists the locking cap 105 and avoids loosening caused by vibration after pipe connection.

[0024] At the same time, the fitting ring 114 is located on one side of the fastening cap 111, the lead screw 113 is located on the inner side of the fastening cap 111, the mounting cylinder 117 is located on the inner side of the disc body 115, and two limiting rings 116 are located on both sides of the disc body 115, when connecting two disc bodies 115, first, the limiting rings 116 on the inner sides of the two disc bodies 115 are fitted and inserted into the screw rod 103, thereby tightly connecting the two disc bodies 115, then the locking cap 105 is rotated and tightened at the end away from the nut 104, and the fastening cap 111 is rotated and connected on one side of the locking cap 105, the inner side of the fastening cap 111 and the lead screw 113 have threads that are adapted to the outer end of the screw rod 103, and the two are tightly connected by threads, after connection, the fitting ring 114 on the inner side of the fastening cap 111 is fitted with the locking cap 105, which maintains stable connection and also provides buffering through the fitting ring 114 to avoid excessive rigidity after connection. Similarly, the first gasket 109 and the second gasket 110 also provide relief for reducing equipment rigidity, achieving tight fitting while having a certain buffering effect.

[0025] In the embodiment, the mounting of the fastening cap 111 is directly fastened by rotating, and the mounting process is convenient and fast. Since the lead screw 113 in the fastening cap 111 is also threadedly connected with the screw rod 103, the fastening cap 111 is not easily slipped off after being mounted on the screw rod 103, and the vibration after pipeline connection will not cause the fastening cap 111 to fall off. The first gasket 109 and the second gasket 110 are mounted after the screw rod 103 is inserted and connected with the two disc bodies 115, and play a buffering and damping role on the inner side of the screw cap 104 and the inner side of the locking cap 105. After the locking cap 105 is stably rotated at the outer end of the screw rod 103, the fastening cap 111 is rotated and connected at the outer end of the screw rod 103. The length of the fastening cap 111 and the length of the abutting ring 114 are added together and are just the same as the length of the screw rod 103 exposed at the outer end of the locking cap 105. Therefore, after the fastening cap 111 is rotated and connected, the screw rod 103 is not exposed, and the locking cap 105 plays a supporting role while avoiding the loosening effect caused by vibration after pipeline connection. When connecting the two disc bodies 115, first, the limiting ring 116 on the inner side of the two disc bodies 115 is abutted and the screw rod 103 is inserted, so that the two disc bodies 115 are tightly connected.
