DETAILED DESCRIPTION

[0018] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0019] Example: See Figure 1-3The utility model provides a technical solution: a PCCP pipe that is easy to connect. This solution takes into account that traditional PCCP pipes are combined and connected by welding during laying, which will damage the pipeline body, and the construction speed is slow, affecting the construction progress, and the pipeline cannot be recycled later. Based on the above content, this case sets the following technical means;

[0020] Specifically, the device at least includes a PCCP pipe body 1, an insertion pipe 2, a plurality of spherical slots 3, a first combination sleeve 4, a plurality of buckle fixing components, a sleeve pipe 5, a second combination sleeve 6, a limit ring 7, a compression spring 8, an adjustment sleeve 9, a plurality of special-shaped installation cavities 10 and a plurality of combination clamping balls 11;

[0021] The insertion tube 2 of another pipe is inserted into the inside of the sleeve tube 5. The moving adjustment sleeve 9 cooperates with the limit ring 7 to compress the compression spring 8, and at the same time, it can drive the combined clamping ball 11 installed in the special-shaped installation cavity 10 to move to a state where the clamping structure is opened. The insertion tube 2 is inserted into the inside of the sleeve tube 5 and the spherical clamping groove 3 opened on its surface is aligned with the protruding position of the combined clamping ball 11. After loosening the adjustment sleeve 9, the adjustment sleeve 9 will rebound under the drive of the elastic deformation force. At the same time, driven by the inner wall of the special-shaped installation cavity 10, the combined clamping ball 11 is moved to its original position and embedded in the spherical clamping groove 3, thereby realizing the preliminary combined connection between the pipes, and then the connection is further fixed by the buckle fixing component.

[0022] More specifically, the buckle fixing assembly includes: a mounting block 14, a rotating rod 15, a buckle fixing rod 16 and a locking hole 17;

[0023] When the pipeline is combined and connected, the first combination sleeve 4 and the second combination sleeve 6 will be in a tightly fitted state. The rotating rod 15 on the mounting block 14 drives the buckle fixing rod 16 to rotate so that it is stuck to the other side of the second combination sleeve 6, and then the fixing bolt is used to pass through the locking hole 17 and rotate and fix it into the threaded fixing hole 18 to further seal and connect the pipeline.

[0024] In the specific implementation process, further, the positions of the plurality of spherical clamping grooves 3 correspond one to one with the positions of the plurality of combined clamping balls 11 .

[0025] In the specific implementation process, further, an embedding groove 12 for installing the compression spring 8 is opened on the adjustment sleeve 9.

[0026] In the specific implementation process, further, an exposure hole 13 for the protrusion of the assembled clamping ball 11 is opened on the inner wall surface of the sleeve tube 5.

[0027] In the specific implementation process, further, a threaded fixing hole 18 combined and connected with the locking hole 17 is opened on the second combination sleeve 6.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
