Through the internal diameter of the connection cavity 11 that reduces gradually for there is the clearance between the internal face of connecting pipe 2 and connection cavity 11, thereby realize that adhesive linkage 3 is located the clearance and connect in connecting pipe 2 and T tower joint 1, increased and connected area of contact, strengthened the joint strength between connecting pipe 2 and the T tower joint 1, improved T tower connecting device's stability greatly. Simultaneously, the internal diameter of at least one connection cavity 11 in a plurality of connection cavity 11 is greater than the external diameter of connecting pipe 2 for connecting pipe 2 is convenient for insert to connection cavity 11 in, and assembly operation is more convenient, improves work efficiency.
The end face of the connection pipe 2 abuts against the inner wall face of the T-tower 1. Connecting pipe 2 leans on the contact inserting in T tower joint 1 and with the internal face of T tower joint 1, when pouring into adhesive linkage 3 to the clearance in, between adhesive linkage 3 will not leak the terminal surface of connecting pipe 2 and the internal face of T tower joint 1, guaranteed that T tower joint 1 is interior can not get into adhesive linkage 3 and take place blocking phenomenon, improved T tower connecting device's stability. Wherein, the bonding layer 3 is shadowless glue.
Connecting pipe 2 and T tower joint 1's material all can be the PVC material, connecting pipe 2 insert in T tower joint 1 also can with T tower joint 1 between the internal face interference fit, connecting pipe 2's outer wall face and one of them be connected between the internal face of cavity 11 interference fit and closely support and lean on, have effectively avoided the 3 seepage of adhesive linkage.
The inner space of the connecting cavity 11 is cylindrical, and the connecting cavities 11 are stepped.
