In order to avoid the adhesive portion between recombiner unit divides because being longitudinally pressed onto the power on tubing, such scheme is preferred, and the inside and outside wall in recombiner unit one end all convexes to form semi-arched clinch, and the equal horizontal-extending of the inside and outside wall of the recombiner unit the other end forms adhesive portion; The semi-arched clinch of recombiner unit to be taken in the adhesive portion of adjacent recombiner unit and is fixed by viscose glue.
Such scheme is preferred, and the length of described semi-arched clinch is 15-25mm.
In order to make tubing when being subject to weight, the pressure on it can be evenly distributed on hollow shape fin, and excessive on the inside and outside wall of tubing gently, avoid being damaged by pressure because tube portions is stressed, such scheme is preferred, and described hollow shape fin is arcuate structure, and its rise is 20-120mm.
The pressure be subject to make hollow shape fin is alleviated on the inside and outside wall of tubing in optimal manner, and such scheme is preferred, and the arc length of described hollow shape fin is 10-80mm.
Another implementation of the present invention is as follows:
Described cylindrical tubing matrix comprises inner and outer wall, and outer wall is formed the hollow shape fin of spiral; The cavity inner wall of described hollow shape fin is connected with the enhancing steel band identical with hollow shape fin shape; All extend to its end to the two ends of recombiner unit between the inner and outer wall that the two ends of described enhancing steel band embed recombiner unit, namely enhancing steel band is covered with the whole tube wall of cylindrical tubing matrix.
Such scheme is preferred, and described hollow shape fin is arcuate structure, and its rise is 20-120mm.
Such scheme is preferred, and the arc length of described hollow shape fin is 10-80mm.
Compared with prior art, the present invention has the following advantages:
1, strengthening steel band is arranged on the cavity inner wall of hollow shape fin, and extend to the whole tube wall of cylindrical tubing matrix, not only increase the anti-pressure ability of hollow shape fin, also overcome tubing trough weak link, greatly improve the ring stiffness of tubing, and make tubing uniform-compression, not easily damaged.
2, the bonding location between adjacent recombiner unit is substantially horizontal, makes tubing when being subject to weight, and bonding location problem of Cracking can not occur, and also improves the tensile strength of bonding location, extends the working life of tubing.
3, this integrated steel strip reinforced steel is moulded bellows and is also had good integrity, produces that bulk strength that is workable, tubing is large, the feature of long service life.

Embodiment
Embodiment 1
The present invention is that bellows moulded by a kind of integrated steel strip reinforced steel, as shown in Figure 1, comprises cylindrical tubing matrix 1, described cylindrical tubing matrix 1 primarily of spiral winding and melting adhered multiple recombiner units 2 form.Described recombiner unit 2 comprises inner and outer wall, and outer wall is formed the hollow shape fin 3 of spiral, and the hollow shape fin 3 on each recombiner unit 2 can be 1, also can be multiple, be 1 in the preferred embodiment.As shown in the end view drawing of Fig. 2, the cavity inner wall of described hollow shape fin 3 tightens adherent body and is connected to enhancing steel band 4, and the shape of this enhancing steel band 4 is identical with hollow shape fin 3 shape.The two ends of described enhancing steel band 4 embed between the inner and outer wall of recombiner unit 2 completely, and the two ends strengthening steel band 4 extend until arrive the end of recombiner unit 2 respectively to the corresponding end of recombiner unit 2, namely the whole tube wall that steel band 4 is covered with cylindrical tubing matrix 1 is strengthened, overcome trough weak link, improve whole compressive strength and the ring stiffness of tubing.
The inside and outside wall in recombiner unit 2 side all convexes to form semi-arched clinch 5, and the equal horizontal-extending of the inside and outside wall of recombiner unit 2 opposite side forms adhesive portion 6; The semi-arched clinch 5 of recombiner unit 2 to be taken in the adhesive portion 6 of adjacent recombiner unit 2 and is fixed by viscose glue 7, and the bonding location of substantially horizontal, compares the bonding location of vertical direction, and its anti-pressure ability is stronger, also namely more difficult because of pressurized cracking.The length of described semi-arched clinch 5 is 15-25mm, also the bonding length of i.e. adjacent recombiner unit 2, and such bonding location and bonding length are at pressurized with least easy to crack when stretching.
Described hollow shape fin 3 is arcuate structure, and like this when tubing pressurized, what pressure can be mild is excessive on the inside and outside wall of tubing, improves the anti-pressure ability of tubing.The rise of hollow shape fin 3 and arc length determine and are stressed excessively to the speed on the inside and outside wall of tubing, and the compressive strength of hollow shape fin 3, so the rise of hollow shape fin 3 is extremely important, in the preferred embodiment, the rise of hollow shape fin 3 is 20-120mm, the arc length of hollow shape fin 3 is 10-80mm, within the scope of this, the pressure of tubing releive best, compressive strength and ring stiffness maximum.
