The circle centre position of cross section.
Wherein, the opening angle of the V-type rib is 60 °；The ribs and the both sides angle of the V-type rib are
150°。
Wherein, the opening angle of the V-type rib is 60 °；The ribs and the both sides angle of the V-type rib are respectively
120 ° and 180 °.
Wherein, in addition to, the second tubing, second tubing is arranged in the opening of the V-type rib, with the V-type rib
Both sides be fixedly connected.
Wherein, cross rib is set in second tubing.
Wherein, in addition to, the 3rd tubing, the 3rd tubing is arranged at wherein the one of the ribs and the V-type rib
In the angle on side.
Wherein, in addition to, the 4th tubing, the 4th tubing is arranged at the another side of the ribs and the V-type rib
Angle in.
Internal-rib enhancing helical bellows of the present utility model has good ring stiffness, and can make major diameter bellows,
And impact resistance is stronger.

Obviously, described embodiment is only the utility model part of the embodiment, rather than whole embodiments.Based on this practicality
Embodiment in new, the every other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example is applied, belongs to the scope of the utility model protection.
According to Fig. 1-3, illustrate internal-rib enhancing helical bellows of the present utility model, including inner layer tube wall 1 and outer layer
Tube wall 2, inner layer tube wall are continuous real wall PE inner tubes.The hollow form fin 3 with spiral is formed on outer wall 2；In described
First tubing 4 is set in empty shape fin 3；Ring stiffness is that pipeline resists measuring for circumferential deformation power.Unit is KN/m2.To enter one
The impact resistance and ring stiffness of step enhancing bellows, set ribs 6 and V-type rib 7；Described one end of ribs 6 and the first tubing 4
Inwall bonding connection, the sophisticated of the other end and the V-type rib 7 be connected；The opening both ends of the V-type rib 7 are bonded in described
At the support connection position of the lower half 402 of one tubing 4.The cross section of first tubing 4 is circle, and the tip of V-type rib 7 is located at first
The circle centre position of the cross section of tubing 4.To ensure that ribs 6, V-type rib 7 are fixed in the first tubing 4, filling tree in the first tubing
Fat binding agent.The opening angle of V-type rib is 60 °；The ribs 6 and the both sides angle of the V-type rib 7 are 150 °.Relatively
In existing same size bellows, ring stiffness SN8 experiments, 11.5KN/m can reach2.Shock resistance meets TIR≤10%.
