Further, the opposite face of reinforcement part described in two sides is in symmetrical arcuate structure, and two sides reinforcement part is in straight backwards to face
Face structure.
Further, the connecting bridge is provided with hollow cavity, and the hollow intracavity forming has mutually to hang down with connecting bridge extending direction
Reinforcing rib.
Further, the medial surface for squeezing out main body is covered with the overlay film of HDPE material, the overlay film body coiled coil shape
At the inner wall of the tube body.
The beneficial effects of the present invention are: the present invention with the above structure, reinforcement part is in hollow structure, tube body can be reduced
Weight and material utilization amount reduce production cost, while hollow reinforcement part has certain ring flexibility, in order to basic body
Make coiled coil and makes close adhesion between the reinforcement part of adjacent bed basic body.Squeeze out main body using PP material central core and
The surface layer of HDPE material, the surface layer of HDPE material can improve the heat resistance and cold resistance and corrosion resistance of tube body, while also have
Higher rigidity and toughness, mechanical strength are good.

Specific embodiment
Claimed technical solution of the invention is described in further detail now in conjunction with the drawings and specific embodiments.
Implement one
Referring to figure 1 and figure 2.One of the present embodiment internal-rib enhances two-component helical bellows, including by extrusion main body 1
The tube body that coiled coil is formed.
In the present embodiment, 1 two sides of main body are squeezed out and are formed with symmetrical reinforcement part 11, while in 11 downside of two sides reinforcement part
Between be connected with connecting bridge 12, the reinforcement part 11 is in hollow structure.Specifically, the opposite face of reinforcement part 11 described in two sides is in pair
The arcuate structure of title, two sides reinforcement part 11 is in face structure directly, while connecting bridge 12 is provided with hollow cavity 121 backwards to face, described
121 internal shaping of hollow cavity has the reinforcing rib 122 mutually to hang down with 12 extending direction of connecting bridge.It is adjacent when squeezing out the progress coiled coil of main body 1
Reinforcement part 11 between layer is bonded to each other, and what it is due to two sides reinforcement part 11 is in face structure directly to be convenient for adding between adjacent bed backwards to face
Strong portion 11 is bonded, and is bonded between reinforcement part 11 using hot melt adhesive in the present embodiment, and hot melt adhesive uses the HDPE of melting, i.e.,
High density polyethylene (HDPE).Reinforcement part 11 and connecting bridge 12 are in hollow structure, can reduce tube body weight and material utilization amount, reduce life
Cost is produced, while hollow reinforcement part 11 and connecting bridge 12 has certain ring flexibility, in order to which basic body makees helical disk
Around and make close adhesion between the reinforcement part 11 of adjacent bed basic body, reason is to squeeze out main body 1 when carrying out coiled coil
It needs its to carry out a degree of distortion, such as squeezes out that 1 ring flexibility of main body is too small to be will lead to it and be difficult to distort or generate in the warped
Larger stress causes to bond between reinforcement part 11 insecure.
In the present embodiment, the extrusion main body 1 including central core 1b and is coated on the central core 1b inner and outer surfaces
Surface layer 1a(reinforcement part 11 hollow cavity 121 and hollow cavity 121 inner wall by the surface layer 1a coat), wherein in described
Central layer 1b is PP material, and the surface layer 1a is HDPE material.Main body 1 is squeezed out using central core 1b and the HDPE material of PP material
Surface layer 1a, the surface layer 1a of HDPE material can improve the heat resistance and cold resistance and corrosion resistance of tube body, while also have higher
Rigidity and toughness, mechanical strength is good.
Embodiment two
Shown in Figure 3, in the present embodiment, internal-rib enhancing two-component helical bellows include by extrusion main body 1 and covering
The tube body that the common coiled coil of overlay film 2 of the HDPE material of 1 medial surface of main body is formed is squeezed out, wherein overlay film 2 is after coiled coil
Constitute the inner wall of tube body.It, can be further by the inboard wall of tube body that 2 coiled coil of overlay film is constituted in the present embodiment compared with embodiment one
Strengthening the structural stability of tube body, especially HDPE material has heat resistance and cold resistance and corrosion resistance, at the same also have compared with
High rigidity and toughness, mechanical strength is good, can further improve the performance of tube body.Although the inboard wall of tube body of embodiment one kind is crowded
1 surface layer 1a of main body is constituted out, and its material is similarly HDPE, however the overlay film 2 in the present embodiment may make up thickness relatively more
The inboard wall of tube body of thick HDPE material, while in production, overlay film 2 and extrusion main body 1 are squeezed out without one, can reduce technique
Difficulty.
Embodiment three
Referring to fig. 4 and shown in Fig. 5, in the present embodiment, hollow cavity 121 carries out welding after seperated with main body 1 is squeezed out can squeezing out again,
Specifically, the rectangular in cross-section structure of hollow cavity 121 and its middle part are formed with reinforcing rib 122, the connecting bridge in extrusion main body 1
12 only retain the sheet structure of connection two sides reinforcement part 11, while there are grooves between two sides reinforcement part 11.Bridge is connect when welding
Hollow cavity 121 is embedded in the groove and carries out welding.Technology difficulty can be reduced through the above way.
The embodiment of the above is only presently preferred embodiments of the present invention, not does limit in any form to the present invention
System.Anyone skilled in the art, without departing from the scope of the technical proposal of the invention, all using the disclosure above
Technology contents more possible variations and retouching are made to technical solution of the present invention, or be revised as the equivalence enforcement of equivalent variations
Example.Therefore all contents without departing from technical solution of the present invention, equivalent equivalence changes, should all cover made by thinking according to the present invention
In in protection scope of the present invention.
