Tube body, not only the technology of bonding is required high, easy to fall off after bonding, scrappage is high, leads to low production efficiency, and ribs
It is bonded by two parts, leads to the easy crooked, deformation of ribs, structural strength is not high, influences the ring stiffness of product entirety, causes
Bearing capacity is insufficient, directly affects the performance of product.
Therefore, how to solve the problems of the above-mentioned prior art becomes the direction of field technology personnel effort.
Utility model content
The purpose of this utility model is just to provide a kind of internal-rib enhancing polyethylene helical bellows, can be fully solved above-mentioned existing
There is the shortcoming of technology.
The purpose of this utility model is realized by following technical proposals：
A kind of internal-rib enhances 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 set in the middle part of substrate, and substrate is integrally formed with closing chamber, the envelope
Ribs is equipped in closed chamber, in banding sheet material spiral winding, the abutted surface of substrate forms the bonding plane of horizontal direction.
Preferably, 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
It is flushed with the top surface of right substrate.
Preferably, the closing chamber is rectangular configuration, bottom end connects with substrate, and joint is arc-shaped transition, is sealed
Closed chamber top both sides corner uses arc-shaped transition.
Preferably, the ribs is vertically arranged the reinforcing rib at the 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 utility model are：
1. simple in structure, reasonable 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 promote the bearing capacity of bellows and ring stiffness；
2. by bonding plane change of the tradition in closing chamber to closing chamber both sides, bonding plane is changed to level side by vertical direction
To reducing adhesive technology and technological requirement, be conducive to machine-shaping, reduce scrappage, improve production efficiency；
3. closing chamber uses integrally formed mode, be conducive to reduce the wall of ribs in the case where ensureing ring stiffness
Thickness so as to reduce production materials, and then saves cost, promotes product competitiveness.

Specific embodiment
The utility model is further described with reference to specific embodiments and the drawings.
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 tube body being mutually bonded, the banding sheet material include substrate 1 and the closing chamber 2 being set in the middle part of 1 top surface of substrate, 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 2 left side of the closing chamber is left substrate 101, and the substrate on right side is right substrate 102, the bottom of left substrate 101
Face is flushed 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 vertically arranged the reinforcing rib at the 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 end connects with substrate 1, and joint be arc-shaped transition, rectangle
Lug boss top both sides corner uses arc-shaped transition.The rectangular preiection portion and substrate 1 by mold disposal integral molding, because
This, the ribs 3 and disposal molding in closing chamber 2 that rectangular preiection portion is surrounded with substrate 1, the center line and base of ribs 3
1 center line of plate overlaps, and so as to which the structural strength of ribs 3 be effectively ensured, avoids its diagonal distortion, promotes 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, is conducive to machine-shaping, reduces scrappage, improves production efficiency.
The utility model changes the position of bonding plane, and bonding plane of the tradition in closing chamber is changed to closing chamber both sides, is being promoted
The difficulty of processing and manufacturing is also reduced while product bearing capacity and ring stiffness, improves production efficiency.
Due to 4 position change of bonding plane so that ribs 3 can disposal molding, therefore, ensure product bearing capacity and
Be conducive to reduce the wall thickness of ribs in the case of ring stiffness, so as to reduce production materials, and then save cost, it is competing to promote product
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 is with embodiment one, the difference lies in the ribs 3 is horizontally disposed V-arrangement
Structure.
Embodiment three
As shown in figure 8, the present embodiment is with embodiment one, the difference lies in the ribs 3 is X-shaped structure.
