The utility model discloses a change the structure of strip for bellows after the winding shaping has better mechanical properties.
Description
Technical field
The utility model is related to a kind of municipal administration pipe, particularly helical bellows.
Background technology
Taking municipal blow-off line engineering as a example, in order to prevent effluent seepage environmental protection, widely used bigbore mould
Material drainpipe.Current plastic drain-pipe divides two types, a kind of be made up of pure plastics, such as polyethylene or PVC-U
Double-wall corrugated pipe, polyethylene winding structure wall pipe, another kind is the drainpipe that clad steel brings composition in plastic tube wall, such as
Steel band reinforced polyethylene spiral ripple pipe, polyethylene plastic-steel winding pipe, Double-flat wall steel plastic drainpipe etc..Send out during actually used
Existing, the drainpipe that wherein pure plastics are made is commonly present body bonding and loosely leads to the crackly problem of body, and is compounded with steel
The plastic drain-pipe of band then has steel band, and easily corrosion leads to the quality problems occurring, and is therefore required for further perfect.
Utility model content
The technical problems to be solved in the utility model is：There is provided a kind of bonding stronger helical bellows.
The solution that the utility model solves its technical problem is：Internal-rib enhanced polyethylene PE helical bellows band,
Include bottom, described bottom is provided with and is integrally formed cavity with it, described bottom and cavity are PE material, described cavity bag
Straight wall and arcwall are included, described straight wall is located at the outside of bottom, described arcwall is located at the inner side of bottom, and described straight wall sets
Have a reinforcement, described reinforcement while with straight wall while flush；Described cavity has two, described two cavitys mirror image pair each other
Claim.
As the improvement further of technique scheme, described bottom is identical with the wall thickness of two cavitys.
As the improvement further of technique scheme, described arcwall is made up of the camber line of three sections of different curvature, every section
The junction rounding off of camber line.
The beneficial effects of the utility model are：The utility model passes through to change the structure of band so that after Wrapping formed
Bellows has more preferable mechanical property.
Brief description
In order to be illustrated more clearly that the technical scheme in the utility model embodiment, below will be to required in embodiment description
Accompanying drawing to be used is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, rather than entirely
Portion's embodiment, those skilled in the art's on the premise of not paying creative work, it can also be obtained according to these accompanying drawings
His design and accompanying drawing.
Fig. 1 is section view of the present utility model；
Fig. 2 is the section view of embodiment two of the present utility model.
Specific embodiment
Below with reference to embodiment and accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is carried out
Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of embodiment of the present utility model, rather than whole embodiments, based on embodiment of the present utility model, the skill of this area
The other embodiment that art personnel's on the premise of not paying creative work is obtained, belongs to the model of the utility model protection
Enclose.In addition, all connection/annexations being previously mentioned in literary composition, not singly refer to component and directly connect, and refer to can be according to concrete reality
Apply situation, by adding or reducing connection auxiliary, to form more excellent draw bail.Each technology in the invention is special
Levy, can be with combination of interactions on the premise of not conflicting conflict.
With reference to Fig. 1, internal-rib enhanced polyethylene PE helical bellows band, include bottom 11, described bottom 11 is provided with
It is integrally formed cavity 12 with it, described bottom 11 is PE material with cavity 12, and described cavity 12 includes straight wall 121 and arc
Wall 122, described straight wall 121 is located at the outside of bottom 11, and described arcwall 122 is located at the inner side of bottom 11, in described straight wall 121
Be provided with reinforcement 13, described reinforcement 13 while with straight wall 121 while flush；Described cavity 12 has two, described two cavitys
12 specular each other.When Wrapping formed, band is mutually closely to get together, and then irrigates between straight wall 121
Glue, so that two adjacent bands can closely connect, then goes to bear the pressure of outside using arcwall, plays good
Resistance to compression act on, straight wall is provided with reinforcement simultaneously, can strengthen the anti-pressure ability of bellows further, and the side of reinforcement with
The side of straight wall flushes so that band connects when bonding is easier reliability.
It is further used as preferred embodiment, described reinforcement 13 is in 1/4 circle, described reinforcement 13 is located at straight wall
121 with the junction of bottom 11.When band is receiving described in external pressure, pressure is delivered on reinforcement by straight wall, profit
Pressure uniformly can be discharged to bottom with the shape of reinforcement.
With reference to Fig. 2, described reinforcement 13 semicircular in shape, described reinforcement 13 is located at the centre of straight wall 121.Reinforcement is set
Put the centre in straight wall, so that stress is evenly.Semicircular reinforcement is Wrapping formed in two bands, it will obtain one
The middle reinforced rib of individual similar round, this reinforcement can bear the pressure of all directions well, improves the overall strong of bellows
Degree.
It is further used as preferred embodiment, described bottom 11 is identical with the wall thickness of two cavitys 12.Uniform wall thickness
Its mechanical property of band more preferably, reduces the harmful effect that stress concentration is brought as far as possible.
It is further used as preferred embodiment, described arcwall 122 is made up of the camber line of three sections of different curvature, every section of arc
The junction rounding off of line.Arcwall is made up of the camber line of three sections of different curvature, can play good mechanical property
Meanwhile, reducing the occupancy in space, thus reducing materials, saving cost of manufacture.
Above better embodiment of the present utility model is illustrated, but the invention be not limited to described
Embodiment, those of ordinary skill in the art also can make a variety of equivalent changes without prejudice on the premise of the utility model spirit
Type or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
