Abstract

The utility model discloses a kind of detachable bellowss, including multiple bellows pieces being mutually adapted, are mutually permanently connected between the two neighboring bellows piece by flange, the reinforcer for having connected each bellows piece is equipped on the flange.The detachable of the utility model is that bellows its structure is simple and easy to disassemble, and the bonding strength after connection in length is higher, not flexible.

Description

Detachable bellows

Technical field

The utility model relates to a kind of detachable bellowss.

Background technique

Currently, bellows is widely used in the every field such as engineering pipeline, vacuum equipment.And existing application it is most be Integral type bellows, both ends are by flanged joint, however, such bellows is limited to volume, weight and length, single ripple Pipe all exerts a certain influence to construction and transport.

On the other hand, if simply shorter multiple bellowss are stitched together, since the bonding strength in length is inadequate, Entire bellows is easily bent after splicing, in terms of there are problems that degree of disturbing.

In the art, it is still necessary to want a kind of removable assemblnig New corrugated pipe, to meet Modern Construction requirement.

Utility model content

The purpose of this utility model is to overcome deficiencies in the prior art, provide a kind of detachable bellows.

In order to achieve the above object, being achieved through the following technical solutions:

A kind of detachable bellows, including multiple bellows pieces being mutually adapted, the two neighboring bellows piece Between be connected with each other by flange, be equipped with the reinforcer for having connected each bellows piece on the flange.

Preferably, the reinforcer is equipped on the two neighboring flange.

Preferably, the reinforcer is worn along the length direction for being parallel to the bellows piece.

Preferably, the flange includes the extension ear extended along the bellows piece radial direction, and the reinforcer is worn In the end for extending ear.

Preferably, two extension ears for being located at two sides are offered on the same flange.

Preferably, each extension ear in the same side is contacted affixed by a reinforcer.

Preferably, the reinforcer is straight rod member.

Preferably, it is tightly connected between the two neighboring bellows piece by sealing ring.

The beneficial effects of the utility model include:

By having the flange for extending ear, while single bellows is connected, and increase bonding strength can be worn Straight-bar, with this prevent the entire bellows being stitched together be bent, meanwhile, be also convenient for dismounting.

Detailed description of the invention

Fig. 1 is the overall structure diagram of the utility model detachable bellows.

Fig. 2 is the structural schematic diagram of upper left side along its length in corresponding diagram 1.

Fig. 3 is the schematic cross-sectional view for going up cross section in corresponding diagram 1 along its length.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawing:

As shown in Figure 1 to Figure 3, a kind of detachable bellows is adjacent including multiple bellows pieces 1 being mutually adapted It is mutually permanently connected between two bellows pieces 1 by flange 2, is equipped on the flange 2 and has connected each wave The reinforcer 3 of line pipeline section 1.

Specifically, the flange 2 includes the extension ear 20 extended along 1 radial direction of bellows piece, the reinforcer 3 It is arranged in the end for extending ear 20.

More preferably, two extension ears 20 for being located at two sides are offered on the same flange 2.It is described Reinforcer 3 is that (certainly, reinforcer is not limited to rod piece to straight rod member, is also possible to other works commonly used in the art with certain rigidity Part, such as long bolt, long sleeve etc.).Connected between the end of the two neighboring bellows piece 1 by the sealing of sealing ring 4 It connects.

Preferably, it is equipped with the straight rod member 3 on the two neighboring flange 2, the straight rod member 3 is along being parallel to the wave The length direction of line pipeline section 1 is worn, and each extension ear 20 in the same side is contacted affixed by a straight rod member 3.

Detachable bellows provided by the utility model, structure is simple and easy to disassemble, after connection in length Bonding strength is higher, not flexible.

The embodiments of the present invention are only used for being illustrated the utility model, do not constitute to scope of the claims Limitation, other substantially equivalent substitutions that those skilled in that art are contemplated that, in the protection model of the utility model In enclosing.
