Abstract
The utility model discloses a kind of steel strip reinforced bellows, comprise body, body comprises outward corrugated tube and interior pipe, is circumferentially evenly provided with many steel bands axially arranged between outward corrugated tube and interior pipe, be evenly distributed with steel loop by corrugated vertically between steel band and interior pipe, the cross section of steel loop is arc-shaped.Many the steel bands axially arranged circumferentially evenly are provided with between the outward corrugated tube of this steel strip reinforced bellows and interior pipe, steel loop is evenly distributed with by corrugated vertically between steel band and interior pipe, the cross section of steel loop is arc-shaped, the design of the steel loop distributed by steel band and corrugated strengthens the intensity of this bellows greatly, interior pipe and the stressed of outward corrugated tube can carry out flexible buffering by undulatory steel loop, improve the resistivity of bellows in the face of impacting, steel band promotes bellows croos strength, bellows transverse breakage can be prevented, the intensity of this bellows of General Promotion, extend the working life of bellows.
Description
Technical field
The utility model relates to a kind of tubing, particularly relates to a kind of steel strip reinforced bellows.
Background technique
Plastic film capicitor product is attractive in appearance, Portable durable, be widely used in multiple fields, through the development of nearly 30 years, all relative maturity in equipment, forming technique, technique and raw material, the material of plastic film capicitor is extended to the raw materials such as PE, PP gradually from PVC, and the caliber of plastic film capicitor is also progressively to heavy caliber future development.Limited due to plastics self-strength, therefore, the bellows intensity prepared is also limited.So there is steel strip reinforced bellows, although employed steel band to strengthen plastic film capicitor, but need compared with in the occasion of high impact in the occasion higher to requirement of strength and some, existing steel strip reinforced bellows still can not meet usage requirement, needs to improve bellows structure further.
Model utility content
For solving the problems of the technologies described above, the utility model devises a kind of steel strip reinforced bellows.
The utility model adopts following technological scheme:
A kind of steel strip reinforced bellows, comprise body, body comprises outward corrugated tube and interior pipe, is circumferentially evenly provided with many steel bands axially arranged between outward corrugated tube and interior pipe, be evenly distributed with steel loop by corrugated vertically between steel band and interior pipe, the cross section of steel loop is arc-shaped.
As preferably, be socketed with PE corrugated ring outside described steel loop, PE corrugated ring is fixedly connected with steel band respectively with interior pipe, steel loop, and steel loop is fixedly connected with steel band, and steel band is fixedly connected with outward corrugated tube.
As preferably, described PE corrugated ring and steel band and steel loop bond fixing respectively by binding resin.
Compared with prior art, many the steel bands axially arranged circumferentially evenly are provided with between the outward corrugated tube of this steel strip reinforced bellows and interior pipe, steel loop is evenly distributed with by corrugated vertically between steel band and interior pipe, the cross section of steel loop is arc-shaped, the design of the steel loop distributed by steel band and corrugated strengthens the intensity of this bellows greatly, interior pipe and the stressed of outward corrugated tube can carry out flexible buffering by undulatory steel loop, improve the resistivity of bellows in the face of impacting, steel band promotes bellows croos strength, bellows transverse breakage can be prevented, the intensity of this bellows of General Promotion, extend the working life of bellows.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of left view of Fig. 1;
In figure: 1, outward corrugated tube, 2, interior pipe, 3, steel band, 4, steel loop, 5, PE corrugated ring.
Embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described specifically:
Embodiment: as shown in Figures 1 and 2, a kind of steel strip reinforced bellows, comprise body, body comprises outward corrugated tube 1 and interior pipe 2, eight steel bands 3 axially arranged circumferentially evenly are provided with between outward corrugated tube and interior pipe, steel loop 4 is evenly distributed with by corrugated vertically between steel band and interior pipe, the cross section of steel loop is arc-shaped, PE corrugated ring 5 is socketed with outside steel loop, PE corrugated ring and interior pipe, steel loop is fixedly connected with respectively with steel band, steel loop is fixedly connected with steel band, steel band is fixedly connected with outward corrugated tube, PE corrugated ring and steel band and steel loop bond fixing respectively by binding resin.
Eight steel bands axially arranged circumferentially evenly are provided with between the outward corrugated tube of this steel strip reinforced bellows and interior pipe, steel loop is evenly distributed with by corrugated vertically between steel band and interior pipe, the cross section of steel loop is arc-shaped, the design of the steel loop distributed by steel band and corrugated strengthens the intensity of this bellows greatly, interior pipe and the stressed of outward corrugated tube can carry out flexible buffering by undulatory steel loop, improve the resistivity of bellows in the face of impacting, steel band promotes bellows croos strength, bellows transverse breakage can be prevented, the intensity of this bellows of General Promotion, extend the working life of bellows.
Above-described embodiment is one of the present utility model preferably scheme, not does any pro forma restriction to the utility model, also has other variant and remodeling under the prerequisite not exceeding the technological scheme described in claim.
