[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Example like Figure 4 , 5As shown, the connector interface 2 includes two sets of connecting cylinders 201 on one side of the connector body 1. A metal bellows 202 is connected between the connecting cylinders 201. Four sets of guide plates 203 are provided on one side of each set of connecting cylinders 201. Positioning holes 204 are evenly opened on the guide plates 203. The intermediate adjustment component 3 includes a sleeve 301. Four sets of guide grooves 302 are opened on the surface of the sleeve 301. Two sets of limiting rings 303 are sleeved on one side of the sleeve 301. An adjustment ring 304 is sleeved on the outside of the sleeve 301. A limiting bead 305 that cooperates with the positioning hole 204 is provided on the inside of the adjustment ring 304.

[0018] It should be noted that in this embodiment, when the length of the metal bellows 202 needs to be adjusted, the adjusting ring 304 is first rotated to separate the conical surface on the inner side of the adjusting ring 304 from the limiting bead 305. Under the action of its own elastic element, the limiting bead 305 exits from the positioning hole 204. At this time, the operator pushes or pulls the two sets of connecting cylinders 201 with both hands. One set of connecting cylinders 201 is connected to the sleeve 301, thus causing the sleeve 301 to slide on the surface of the metal bellows 202, thereby driving the guide plate 203. Sliding within the guide groove 302 of the sleeve 301, since the two sets of connecting cylinders 201 are fixedly connected to the metal bellows 202 respectively, the metal bellows 202 will extend and retract with the sliding of the guide plate 203, thereby achieving length adjustment. When the desired length is reached, the adjusting ring 304 is rotated in the opposite direction, and the conical surface on the inner side of the adjusting ring 304 presses the limiting bead 305, so that the limiting bead 305 is inserted into the corresponding positioning hole 204 on the guide plate 203, thereby fixing the length of the metal bellows 202 and completing the adjustment operation. An elastic component is provided between the adjusting ring 304 and the limiting bead 305. When the adjusting ring 304 rotates, the elastic component is squeezed, causing the limiting bead 305 to disengage from the positioning hole 204 on the guide plate 203. When the adjusting ring 304 rotates in the opposite direction, the elastic component resets, allowing the limiting bead 305 to snap into the corresponding positioning hole 204. The limiting ring 303 serves as the mounting component of the adjusting ring 304 on the surface of the sleeve 301. This technology is a conventionally applied existing technology, and its specific structure, material selection, and assembly method will not be described in detail here. Optionally, when the metal bellows 202 is fully extended, the guide plate 203 provides support for the metal bellows 202. The guide plate 203 of different widths can be adapted according to the volume or weight transported by the pipeline to ensure sufficient support for the metal bellows 202.

[0019] like Figure 1-3As shown, it includes a connector body 1, a connector interface 2, and an intermediate adjustment component 3. A sealing groove 101 is provided on one side of the connector body 1, and a sealing ring 102 is installed in the sealing groove 101. The connecting cylinder 201 slides in cooperation with the guide groove 302 of the sleeve 301 through the guide plate 203. One set of connecting cylinders 201 has an internal thread on its inner wall and is threaded to the connector interface 2. The other set of connecting cylinders 201 has an external thread on one side. The inner diameter of the connector body 1 is the same as that of the metal bellows 202. The sleeve 301 is fitted on the outside of the metal bellows 202, and the outer diameter of the sleeve 301 is the same as that of the connecting cylinder 201.

[0020] It should be noted that in this embodiment, the two ends of the connector body 1 are machined with external thread structures. One end of the connecting cylinder 201 in the connector interface 2 is provided with an internal thread that matches the external thread of the connector body 1. Through thread engagement, the connector body 1 and the adjacent connecting cylinder 201 are tightly connected. The other connecting cylinder 201 has an external thread structure protruding from the side away from the metal bellows 202. Both sets of connecting cylinders 201 are fixedly connected to both ends of the metal bellows 202 by welding, ensuring a tight connection. For sealing and structural strength, the sleeve 301 of the intermediate adjustment component 3 is sleeved on the outside of the metal bellows 202, and one end is fixedly connected to the connecting cylinder 201 away from the joint body 1. When the length of the metal bellows 202 is not adjusted, the other end of the sleeve 301 is close to another connecting cylinder 201. At the same time, the guide plate 203 and the connecting cylinder 201 close to the joint body 1 are integrally formed. The guide plate 203 is embedded in the guide groove 302 of the sleeve 301 and can slide in the guide groove 302 to provide guidance for length adjustment. In this case, both the connecting end face of the connector body 1 and the connecting end face of the connecting cylinder 201 away from the connector body 1 are provided with sealing grooves 101, and sealing rings 102 are installed in the sealing grooves 101 to ensure the sealing of the connection.

[0021] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-5 The two ends of the connector body 1 are machined with external thread structures. One end of the connector interface 1 is threaded to the pipe, and the other end of the connector interface 2 is connected to the connecting cylinder 201 close to it by thread engagement. The other connecting cylinder 201 has an external thread structure protruding on the side away from the metal bellows 202 for connecting the equipment interface. Both sets of connecting cylinders 201 and the two ends of the metal bellows 202 are fixedly connected by welding to ensure the sealing and structural strength of the connection. The sleeve 301 of the intermediate adjustment component 3 is sleeved on the outside of the metal bellows 202, and one end is fixedly connected to the connecting cylinder 201 away from the joint body 1. When the length of the metal bellows 202 is not adjusted, the other end of the sleeve 301 is close to another connecting cylinder 201. At the same time, the guide plate 203 and the connecting cylinder 201 close to the joint body 1 are integrally formed. The guide plate 203 is embedded in the guide groove 302 of the sleeve 301 and can slide in the guide groove 302 to provide guidance for length adjustment. When it is necessary to adjust the length of the metal bellows 202, first rotate the adjusting ring 304 to separate the conical surface on the inner side of the adjusting ring 304 from the limiting bead 305. Under the action of its own elastic element, the limiting bead 305 exits from the positioning hole 204. At this time, the operator pushes or pulls the two sets of connecting cylinders 201 with both hands. One set of connecting cylinders 201 is connected to the sleeve 301, thus causing the sleeve 301 to slide on the surface of the metal bellows 202, and then causing the guide plate 203 to slide in the guide groove 302 of the sleeve 301. Since the two sets of connecting cylinders 201 are fixedly connected to the metal bellows 202, the metal bellows 202 will extend and retract with the sliding of the guide plate 203, thereby realizing the length adjustment. Once the desired length is achieved, rotate the adjusting ring 304 in the opposite direction. The conical surface inside the adjusting ring 304 presses against the limiting bead 305, causing the limiting bead 305 to engage in the corresponding positioning hole 204 on the guide plate 203, thereby fixing the length of the metal bellows 202 and completing the adjustment operation.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
