Fig. 2 is the partial enlarged view at A in Fig. 1.
In figure：HDPE bellowss 1；Tube body 1-1；Ripple bar 1-2；External screw thread 1-3；Steel band 1-4；Connector 2；Internal thread 2-
1；Seal groove 2-2；Spacing ring 2-3；Raw material band 3；Ring type seal 4.
Specific implementation mode
In Fig. 1,2, the utility model is related to municipal works fields, connect and tie more specifically to HDPE bellowss
Structure, including：HDPE bellowss 1, connector 2, raw material band 3 and ring type seal 4, installation is convenient, and connection sealing is good, makes
Valence advantage of lower cost uses convenient for promoting to produce in enormous quantities.
HDPE corrugated pipe connection structures, there are two HDPE bellowss 1, two HDPE bellowss 1 company of being threaded in respectively
The both sides of fitting 2, raw material band 3 are sealed in HDPE bellowss 1 and 2 threaded connection place of connector, and ring type seal 4 is arranged in HDPE
Between bellows 1 and connector 2；
HDPE bellowss 1 include tube body 1-1, ripple bar 1-2, external screw thread 1-3 and steel band 1-4, the setting of ripple bar 1-2 spirals
In the outer surface of tube body 1-1, external screw thread 1-3 is arranged on the ripple bar 1-2 in HDPE bellowss 1 at tip position, steel band
The cementing inside for being fixed on ripple bar 1-2 1-4；
Internal thread 2-1, seal groove 2-2 and spacing ring 2-3 are provided on connector 2, internal thread 2-1 there are two sections, sets respectively
Set the both ends in 2 inside of connector；The centre position in 2 inside of connector, spacing ring 2-3 and connector 2 is arranged in spacing ring 2-3
Outer wall between cavity be seal groove 2-2.
The HDPE bellowss 1, connector 2 and ring type seal 4 are coaxial, are conducive to whole assembly.
It is connect with internal thread 2-1 matching threads by external screw thread 1-3 between the HDPE bellowss 1 and connector 2.
The raw material band 3 is sealed between external screw thread 1-3 and internal thread 2-1, and raw material band 3 plays the role of sealing waterproof.
The internal orifice dimension of the tube body 1-1 is slightly larger than the outer diameter of spacing ring 2-3 so that the end of HDPE bellowss 1 is easier
It is screwed into spacing ring 2-3 so that the end face of tube body 1-1 is slightly squeezed to ring type seal 4, plays better seal waterproof effect.
4 material of the ring type seal is nitrile rubber.
The operation principle of the utility model：Before site operation, by lathe by screw thread over 1 both ends of HDPE bellowss
