In order to realize the above object technical scheme is used by the utility model：
Hook strangles the double rubber ring PP skeletons enhancing PE helical corrugation pipe joints of formula, including helical bellows and be formed separately in
The female joint at helical bellows both ends and sub- joint, the sub- joint are included along perpendicular to the extension of helical corrugation end surfaces direction
Socket part, the socket part outer wall leave two circle outer grooves, and two outer grooves cover Le respectively two circle O-ring seals；The mother
Joint includes the sleeve for socket part described in jacket, and the sleeve lining is formed with Liang Quan and two O-ring seals correspond
Inner groove；Turn over to form the overhead structure for hooking inner groove after two O-ring seals.
Further, it is interference fitted between the female joint and sub- joint.
Further, the section undulate structure of the O-ring seal.
Preferably, described female joint uses HDPE materials.
Preferably, described sub- joint uses HDPE materials.
The beneficial effects of the utility model are：Helical bellows in the utility model is connect using the sub- joint of end and mother
Head is docked, and turning over the overhead structure to be formed after the O-ring seal on its neutron joint can hook O-ring seal in female joint
Annular groove prevents sub- joint separates with female joint from coming off, and its overhead structure also plays guiding when sub- joint and female joint dock and made
With making both smoothly dock.Simultaneously fluid sealant snare strangle can be prevented on the outer groove of sub- joint docking when O-ring seal in son
Shifted on joint.

Embodiment
The utility model technical scheme claimed is made further specifically in conjunction with the drawings and specific embodiments
It is bright.
Referring to shown in accompanying drawing 1, the hook in the present embodiment strangles the double rubber ring PP skeletons enhancing PE helical corrugation pipe joints of formula, bag
Include helical bellows 1 and be formed separately the female joint 3 in the both ends of helical bellows 1 and sub- joint 2.In the present embodiment, spiral shell
Hot-melt adhesive paste is carried out between rotation bellows 1 and sub- joint 2 and female joint 3 to fix.
Its neutron joint 2 is included along perpendicular to the socket part 21 of the end face direction of helical bellows 1 extension, the outer wall of socket part 21
Two circle outer grooves 22 are left, two outer grooves 22 cover Le respectively there are two circle O-ring seals 4；Female joint 3 includes to be socketed for jacket
The sleeve 31 in portion 21, the inner wall forming of sleeve 31 have 4 one-to-one inner groove 32 of Liang Quan and two O-ring seals；Two O-ring seals 4
The overhead structure to be formed and hook inner groove 32 is turned over afterwards.
It is attached in the following manner between two helical bellowses 1 in the present embodiment：Allow a helical corrugation first
The sub- joint 2 of pipe 1 is relative with the female joint 3 of another helical bellows 1, then allows sub- joint 2 to insert in female joint 3 and realizes two
Person is mutually butted.After docking, set strangles two inner grooves 32 that can buckle into female joint 3 simultaneously in two O-ring seals 4 on sub- joint 2
It is interior, and hooked female joint 3 using the overhead structure to be formed is turned over after O-ring seal 4, prevent both from releasing.In the present embodiment,
The external diameter of sub- joint 2 also realizes both interference fits slightly larger than the internal diameter of female joint 3, makes both connections closer.In addition, this
The section of O-ring seal 4 also undulate structure in embodiment, the structure are advantageous to improve the sealing of O-ring seal 4, and
It is more convenient for connecting.Specifically, the O-ring seal 4 of wavy shaped configuration is close to form Multi-level sealing structure with inner groove 32, works as spiral
Bellows 1 meet with infiltration when, O-ring seal 4 can play sealing function barrier infiltration, but when infiltration phenomenon further aggravate or
When there is partial aperture between person's O-ring seal 4 and inner groove 32, water can be along the gap between O-ring seal 4 and inner groove 32
To the internal penetration of helical bellows 1, but the wavy shaped configuration of O-ring seal 4 is utilized, water penetration can be worked as to the ripple of O-ring seal 4
During peak edge, trough internal resistance sealing can be first flowed into all along the gap penetration between O-ring seal 4 and inner groove 32, improved close
Feng Xing.The wavy shaped configuration of O-ring seal 4 also more easily produces elastic deformation in docking and realizes that avoidance acts on, consequently facilitating sub
Joint 2 and the Butt Assembling of female joint 3.
In the present embodiment, helical bellows 1 include formed by the coiled coil of band 11 body, be coiled in tube wall
Reinforcing strip 12 and be covered in body and the coating 13 of the outer surface of reinforcing strip 12 simultaneously, the both sides of band 11 form hollow
Ribs 111, while leave groove 112 between two side stringers 111；Reinforcing strip 12 winds and is nested in groove 112 tight
Paste two side stringers 111 to opposite and the bottom surface of groove 112, the knot of helical bellows 1 is further fixed using reinforcing strip 12
Structure, improve structural stability.In the present embodiment, the band 11 of body uses HDPE (high density polyethylene (HDPE)) material, reinforcing strip
12 use PP (polypropylene) materials and reduce weight in tubular construction, and coating 13 equally uses HDPE (high density polyethylene (HDPE))
Material, its be coated on body and the outer surface of reinforcing strip 12 can by reinforcing strip 12 and body be connected prevent reinforcing strip 12 from
Depart from band 11, and serve the protective effect to reinforcing strip 12.In the present embodiment, in order to allow sub- joint 2 and female joint 3
More preferable with the compatibility of helical bellows 1, sub- joint 2 and the material of female joint 3 use HDPE (high density polyethylene (HDPE)).
Embodiment described above is only preferred embodiment of the present utility model, and any form is not done to the utility model
On limitation.Any those skilled in the art, can profit in the case where not departing from technical solutions of the utility model ambit
Technical solutions of the utility model are made with more possible variations and retouching with the technology contents of the disclosure above, or is revised as equivalent
The equivalent embodiment of change.Therefore all contents without departing from technical solutions of the utility model, the thinking according to the utility model are made
Equivalent equivalence changes, all should be covered by the scope of protection of the utility model.
