[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] Example 1

[0022] like Figures 1 to 3 As shown, a pipe connection device is used to connect water, gas, and other pipelines. The device includes a retractable flexible hose 1, one end of which extends and retracts through a channel in a first connecting disc 2 and is connected to a flange for connection to a pipeline. The other end of the flexible hose 1 extends and retracts through a channel in a second connecting disc 3 and is also connected to a flange for connection to a pipeline. Several retractable structures are provided between the first connecting disc 2 and the second connecting disc 3 to connect them.

[0023] In this embodiment, the pipes to be connected are aligned with the flange at one end of the flexible hose 1 and then connected; the other pipe is aligned with the flange at the other end of the flexible hose 1 and then connected; thus, the pipes to be connected are connected. Since the flexible hose 1 is telescopic and movable, and has a first connecting disc 2 and a second connecting disc 3 for telescopic guidance, the entire connection device maintains a certain degree of "flexibility." This releases the expansion and contraction deformation at the pipe connection caused by thermal expansion and contraction, maintaining a certain degree of mobility and reducing loosening at the pipe connection due to thermal expansion and contraction, thereby reducing water or air leakage at the pipe connection.

[0024] Example 2

[0025] Based on Embodiment 1, the telescopic movable structure of this configuration includes a telescopic rod 4 that can be movably telescopically extended; one end of the telescopic rod 4 is hinged to the first connecting disc 2 via a hinge seat; the other end of the telescopic rod 4 is hinged to the second connecting disc via a hinge seat. Furthermore, each telescopic rod 4 is fitted with a deformation spring 5; one end of the deformation spring 5 is used to connect to the first connecting disc 2, and the other end of the deformation spring 5 is used to connect to the second connecting disc 3.

[0026] In this embodiment, when the pipe connected to the connecting device expands and contracts due to thermal expansion and contraction, the telescopic hose 1 of the connecting device will expand and contract. Thus, one end of the telescopic hose 1 can expand and contract through the channel opening of the first connecting disc 2, and the other end of the telescopic hose 1 can expand and contract through the channel opening of the second connecting disc 3. Furthermore, since the first connecting disc 2 and the second connecting disc 3 are also movable through the telescopic rod 4 and the deformation spring 5, the entire connecting device is in a state of "flexible movement", which can absorb and attenuate the stress deformation caused by thermal expansion and contraction.

[0027] Example 3

[0028] Furthermore, the diameter of the openings in the first connecting disc 2 and the second connecting disc 3 is adapted to the outer diameter of the telescopic hose 1; thus facilitating the telescopic hose 1 to extend and retract through the openings in the first connecting disc 2 and the second connecting disc 3. Simultaneously, the channels of the flanges connected to both ends of the telescopic hose 1 are tapered, allowing the ends of the pipes at the connecting ends to also be tapered, extending into and contacting the tapered channels of the flanges; and the flanges connected to both ends of the telescopic hose 1 are integrally formed with the telescopic hose 1, ensuring a tight seal at the connection. Additionally, the outer walls of the first connecting disc 2 and the second connecting disc 3 are fitted with protective sleeves 6 for protection. The length of the protective sleeves 6 is greater than the length of the first connecting disc 2 and the second connecting disc 3 that can move along the telescopic hose 1; thus, the protective sleeves 6 provide protection for the connection between the first connecting disc 2 and the second connecting disc 3, as well as the telescopic hose 1, ensuring its service life.

[0029] In response, the improved connection device is not only simple in structure, easy to connect, and inexpensive; more importantly, it allows the pipe connection to maintain a certain degree of "flexibility," reducing loosening of the pipe connection due to thermal expansion and contraction, thereby reducing water or air leakage and ensuring the quality of pipeline transportation.
