Abstract
The utility model discloses a kind of bellows,Including steel plate,It is seamlessly connected between the steel plate by polyethylene thin layer,Reinforcement rib is installed with the polyethylene thin layer,And it is installed with ripple block at steel plate both ends,The ripple block is made up of double-layer polyethylene thin layer and steel band,The steel band is fixed between two layers of polyethylene thin layer by resin bed,The steel band is extended to both sides steel plate direction by polyethylene thin layer and is flexibly connected with steel plate by connection ring,And connection ring is arranged on polyethylene coating interior,PVC film is coated with steel plate and ripple the block outer surface,Possesses great crooking ability,And because polyethylene thin layer has toughness in itself,Ripple struction will not be produced inside when steel plate is folded,The influence of internal workpiece is not interfered with,It can also prevent bellows from arbitrarily being folded due to the toughness of polyethylene thin layer,Influence the work of internal workpiece,Bellows it is adaptable.
Description
Technical field
Pipe technology field is the utility model is related to, specially a kind of bellows.
Background technology
In the industry, for some easily by environmental attack and the material of influence, typically can all use pipeline by its
Cladding is got up, therefore in the operation of reality, various protective conduit are using extremely wide.Enter one with protective conduit
Step application, substantial amounts of operation data represent that common protective conduit is primarily present following two defects：First, coating function is limited,
And in the work of high intensity, extremely easy fold crushes；Secondly it is exactly insufficient strength, easily due to colliding with practical operation
Cause bellows bursts etc. reason.
Currently in order to solving this problem mainly uses bellows, due to bellows with certain retractility and with
Certain cushion space, certain buffer capacity can be played to the bending of pipeline, and not interfere with internal protected material
The normal use of material.Bellows is more using enclosed bellows in the market, and this pipeline can be realized preferably
Sealing process, but running through by protection materials can be influenceed in practical operation, influence operating efficiency.And bellows traditionally
In order to further improve bending resistance, typically ripple's depth is further deepened, so as to reach further enhance it is resistant to bending
Ability.However, while ought further improving ripple's depth, can serious shadow because bellows is typically made of metal material
Ring the infringement for the internal normal work for being wrapped by workpiece, resulting even in your not workpiece.
Utility model content
To achieve the above object, the utility model provides following technical scheme：A kind of bellows, including steel plate, the steel
It is seamlessly connected between plate by polyethylene thin layer, reinforcement rib is installed with the polyethylene thin layer, and it is equal at steel plate both ends
Ripple block is installed with, the ripple block is made up of double-layer polyethylene thin layer and steel band, and the steel band is fixed by resin bed
Between two layers of polyethylene thin layer, the steel band, which is extended and passed through with steel plate to both sides steel plate direction by polyethylene thin layer, to be connected
Ring is flexibly connected, and connection ring is arranged on polyethylene coating interior, and it is thin to be coated with PVC on steel plate and ripple the block outer surface
Film.
It is arranged in parallel between the adjacent steel plate as a kind of preferable technical scheme of the utility model, and and polyethylene
Thin layer axial plane is in oblique, and 60 ° -90 ° of oblique angles scope.
As a kind of preferable technical scheme of the utility model, the reinforcement rib is fixedly connected to form one in the shape that intersects
Body structure.
As a kind of preferable technical scheme of the utility model, the ripple block protrudes polyethylene thin layer length 0.5cm.
As a kind of preferable technical scheme of the utility model, the steel band is in arc-shaped ductile structure, and the arc of steel band
Spend between scope π/6- pi/2s.
Compared with prior art, the beneficial effects of the utility model are：The bellows, steel plate is connected by polyethylene thin layer
Connect, possess great crooking ability, and because polyethylene thin layer has toughness in itself, it is interior when steel plate is folded
Portion will not produce ripple struction, not interfere with the influence of internal workpiece, but also can pass through the reinforcement rib control on polyethylene thin layer
Maximum folded degree processed, at the same time, the ripple block at both ends can further improve the control ability of bellows-folded, prevent ripple
Line pipe is arbitrarily folded due to the toughness of polyethylene thin layer, influences the work of internal workpiece, and can be according to the ripple of reality
Effective way and operating environment, come the different ripple blocks used, to improve the adaptability of bellows, and PVC film need not be held
It is stressed, its role is to can prevent the fine particles such as extraneous dust from entering bellows interior.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Embodiment：
Fig. 1 and Fig. 2 are referred to, the utility model provides a kind of technical scheme：A kind of bellows, including steel plate 1, the steel
It is seamlessly connected between plate 1 by polyethylene thin layer 2, is installed with the polyethylene thin layer 2 and strengthens rib 3, and in 1 liang of steel plate
End is installed with ripple block 4, and the ripple block 4 is made up of double-layer polyethylene thin layer 2 and steel band 5, and the steel band 5 passes through tree
Lipid layer 6 is fixed between two layers of polyethylene thin layer 2, and the steel band 5 is extended simultaneously by polyethylene thin layer 2 to the direction of both sides steel plate 1
It is flexibly connected with steel plate 1 by connection ring 7, and connection ring 7 is arranged on inside polyethylene thin layer 2, the steel plate 1 and ripple block 4
PVC film 8 is coated with outer surface.
Preferably, it is arranged in parallel between the adjacent steel plate 1, and be in oblique with the axial plane of polyethylene thin layer 2, and skew angle
Spend 60 ° -90 ° of scope；The reinforcement rib 3 is fixedly connected to form integral structure in the shape that intersects；The ripple block 4 protrudes poly-
The length 0.5cm of vinyl film laminate 2；The steel band 5 is in arc-shaped ductile structure, and between arc range π/6- pi/2s of steel band 5.
Specifically used mode and advantage：The bellows, steel plate is connected by polyethylene thin layer, possesses great bending
Ability, and because polyethylene thin layer has toughness in itself, when steel plate is folded inside will not produce ripple struction,
The influence of internal workpiece is not interfered with, but also maximum folded degree can be controlled by the reinforcement rib on polyethylene thin layer, with this
