It is shown, body is formed by side bonds, the side being mutually bonded forms closing chamber and its interior ribs, this structure are made
Body, not only high to the technical requirements of bonding, easy to fall off after bonding, scrappage is high, causes low production efficiency, and ribs
Formed by two parts bonding, cause the easy crooked, deformation of ribs, structural strength is not high, influences the overall ring stiffness of product, causes
Bearing capacity deficiency, directly affect the performance of product.
Therefore, how to solve the defects of above-mentioned prior art is present becomes the direction that art personnel make great efforts.
The content of the invention
It is an object of the invention to provide a kind of internal-rib to strengthen polyethylene helical bellows, can be fully solved above-mentioned existing skill
The weak point of art.
The purpose of the present invention is realized by following technical proposals：
A kind of internal-rib strengthens polyethylene helical bellows, including by banding sheet material spiral winding and the pipe that is mutually bonded
Body, the banding sheet material includes substrate and the closing chamber being arranged in the middle part of substrate, and substrate is integrally formed with closing chamber, the envelope
Ribs is provided with closed chamber, in banding sheet material spiral winding, the abutted surface of substrate forms the bonding plane of horizontal direction.
Preferably, the substrate on the left of the closing chamber is left substrate, the substrate on right side is right substrate, the bottom surface of left substrate
Flushed with the top surface of right substrate.
Preferably, the closing chamber is rectangular configuration, its bottom connects with substrate, and joint is arc-shaped transition, envelope
Closed chamber top both sides corner uses arc-shaped transition.
Preferably, the ribs is the reinforcement for being vertically arranged in middle part in closing chamber.
Preferably, the ribs is v-shaped structure.
Preferably, the ribs is X-shaped structure.
Compared with prior art, the beneficial effects of the present invention are：
1. simple in construction, reasonable in design, closing chamber is integrally formed with substrate so that the reinforcement rib structure in closing chamber is steady
Gu diagonal distortion is not easy, so as to lift the bearing capacity of bellows and ring stiffness；
2. bonding plane of the tradition in closing chamber is changed and arrives closing chamber both sides, bonding plane is changed to level side by vertical direction
To reducing adhesive technology and technological requirement, be advantageous to machine-shaping, reduce scrappage, improve production efficiency；
3. closing chamber uses integrally formed mode, be advantageous to reduce the wall of ribs in the case where ensureing ring stiffness
Thickness, so as to reduce production materials, and then cost is saved, lift product competitiveness.

Embodiment
With reference to specific embodiments and the drawings, the present invention is further illustrated.
Embodiment one
As shown in Figures 4 to 6, a kind of internal-rib enhancing polyethylene helical bellows, including by banding sheet material spiral winding simultaneously
The body being mutually bonded, the banding sheet material include substrate 1 and the closing chamber 2 being arranged in the middle part of the top surface of substrate 1, and base
Plate 1 is integrally formed with closing chamber 2, and in banding sheet material spiral winding, the abutted surface of substrate 1 forms the bonding plane 4 of horizontal direction,
Concretely, the substrate in the left side of the closing chamber 2 is left substrate 101, and the substrate on right side is right substrate 102, the bottom of left substrate 101
Face flushes with the top surface of right substrate 102, and when spiral winding is bonded, the bottom surface of left substrate 101 connects with the top surface of right substrate 102
Form bonding plane 4.
The ribs 3 is the reinforcement for being vertically arranged in middle part in closing chamber 2, and closing chamber 2 is by a bottom end opening
Rectangular preiection portion surrounded together with substrate 1, rectangular preiection portion bottom connects with substrate 1, and joint is arc-shaped transition, rectangle
Lug boss top both sides corner uses arc-shaped transition.The rectangular preiection portion and substrate 1 by mould disposal integral molding, because
This, the ribs 3 and disposal molding in closing chamber 2 that rectangular preiection portion surrounds with substrate 1, the center line and base of ribs 3
The center line of plate 1 overlaps, and so as to which the structural strength of ribs 3 be effectively ensured, avoids its diagonal distortion, lifts the bearing capacity of bellows
And ring stiffness.
Banding sheet material when spiral winding is bonded, the bottom surface of left substrate 101 connect with the top surface of right substrate 102 to be formed it is Nian Jie
Face 4, so as to reduce adhesive technology and technologic requirement, be advantageous to machine-shaping, reduce scrappage, improve production efficiency.
The present invention changes the position of bonding plane, and bonding plane of the tradition in closing chamber is changed and arrives closing chamber both sides, in lifting product
The difficulty of processing and manufacturing is also reduced while bearing capacity and ring stiffness, improves production efficiency.
Due to the position of bonding plane 4 change so that ribs 3 can disposal molding, therefore, ensure product bearing capacity and
Be advantageous to reduce the wall thickness of ribs in the case of ring stiffness, so as to reduce production materials, and then save cost, lifting product is competing
Strive power.And after the completion of being bonded, bonding plane 4 is hidden in inside, good appearance.
Embodiment two
As shown in fig. 7, the present embodiment and the difference of embodiment one are, the ribs 3 is horizontally disposed V-arrangement
Structure.
Embodiment three
As shown in figure 8, the present embodiment and the difference of embodiment one are, the ribs 3 is X-shaped structure.
