Abstract
The invention discloses a quick coupling of corrugated pipes. The quick coupling comprises a coupling body used for connecting more than two corrugated pipes, and the coupling body includes a main body section and a bell mouth section used for plugging the corrugated pipes; a bell mouth step is arranged between the main body section and the bell mouth section, and a U-shaped ring groove is arranged on the pipe wall of the bell mouth section; a limiting buckle forms in the middle of the U-shaped ring groove, and the limiting buckle comprises a limiting part located at a free end and a connecting part for supporting the limiting part; the limiting part is bent towards the inside of the pipe wall so as to bond with wave crest faces of the corrugated pipes and form unidirectional limit for the corrugated pipes; sealing glue rings sleeve on the corrugated pipes between the limiting buckle and the bell mouth step. The quick coupling of the corrugated pipes can rapidly complete the connection and installation between the corrugated pipes by means of the limiting buckle; moreover, the quick coupling is convenient to install and low in cost.
Description
Technical field
The invention belongs to pipe fitting joint technical field, be specifically related to a kind of quick joint of corrugated pipe.
Background technique
Existing corrugated conduit needs when connecting to adopt inspection shaft to connect usually, and simultaneously supporting with inspection shaft pit shaft, well lid, walling crib etc. in addition, make employing detect well higher to the Placement cost connecting bellows.And the gully of Pipe installing is subject to the impact of execution conditions and construction cost, substantially be all narrow, increase installation difficulty, some places do not allow installation check well due to position reason, increase construction and installation cost, because a variety of causes such as earthquake cause unequal foundation settlement after installing, corrugated conduit and splice failure, joint is easily torn disengagement and is leaked, and easily causes secondary environmental pollution.
Summary of the invention
The object of the invention is to: there is high, the inconvenient problem of installation cost for bellows when connection, a kind of quick joint of corrugated pipe is provided, the connection between bellows and bellows can be completed fast, and easy for installation, cost is low.
To achieve these goals, the technical solution used in the present invention is:
A kind of quick joint of corrugated pipe, comprise the joint body for being connected by the bellows of more than two sections, joint body comprises main paragraph and the socket section for grafting bellows, it is bellmouth step between main paragraph and socket section, the tube wall of described socket section is provided with U-loop groove, limit fastener is formed in the middle of U-loop groove, limit fastener comprises the joint in limited part and the support limit portion being positioned at free end, limited part is used for fitting with the crest face of bellows towards lateral buckling in tube wall, is formed unidirectional spacing to bellows; Bellows between limit fastener and bellmouth step overlaps and has O-ring seal.
Preferably, described limited part is platy structure, and limited part is towards lateral buckling in tube wall, and bending angle α is 30 ° ~ 60 °.
Preferably, described limited part is formed primarily of outer inclined-plane, confined planes and interior inclined-plane, and confined planes keeps vertical with the revolution shaft axis of tube wall.
Preferably, described joint body is tee pipe fitting or bend pipe tools.
Owing to have employed technique scheme, the invention has the beneficial effects as follows:
A kind of quick joint of corrugated pipe of the present invention, when inserting bellows, by having certain flexible joint, bellows can quick insertion socket section, then fitted by the limited part of limit fastener and the crest face of bellows, effective axial limiting can be formed to the bellows inserting socket section, prevent bellows from exiting; Have pressure in the pipeline installing rear joint, but bellows blocks and can not exit, and is provided with the sealing effect that O-ring seal can improve joint effectively simultaneously, can not leaks spacing due to limited buckle; Quick joint of corrugated pipe of the present invention is easy for installation, connects reliable, constructs, the cost of material is low, be not easy to break, damage.

Embodiment
With reference to Fig. 1-5, a kind of quick joint of corrugated pipe, comprise the joint body 10 for being connected by the bellows 20 of more than two sections, joint body 10 is tee pipe fitting, joint body 10 comprises main paragraph 11 and the socket section 12 for grafting bellows 20, it is bellmouth step 15 between main paragraph 11 and socket section 12, the tube wall of described socket section 12 is provided with U-loop groove 14, form limit fastener 13 in the middle of U-loop groove 14, limit fastener 13 comprises and is positioned at the limited part 131 of free end and the joint 132 in support limit portion 131.Limit fastener 13 can arrange 2 ~ 4 along the circumference of socket section 12, can play better limit effect like this.Bellows 20 between limit fastener 13 and bellmouth step 15 overlaps and has O-ring seal 30.
Limited part 131 is platy structure, and limited part 131 is towards lateral buckling in tube wall, and bending angle α is 30 ° ~ 60 °, when α is in this angular interval scope, can meet the requirement of strength of limit fastener 13, and limit fastener 13 is not easy fracture.Limited part 131 is formed primarily of outer inclined-plane 131a, confined planes 131b and interior inclined-plane 131c, and confined planes 131b keeps vertical with the revolution shaft axis of tube wall, and the bellows 20 for various tooth form can both reach good limit effect.
During installation, bellows 20 puts O-ring seal 30, insert socket section 12, when in the limited part 131 that bellows 20 touches limit fastener 13 during inclined-plane 131c, because the joint 132 connecting limited part 131 has certain elasticity, continue to insert bellows 20, limit fastener 13 can be overall towards the direction expansion outside tube wall, until the crest of bellows 20 is successively smoothly by limit fastener 13, and the end face of bellows 20 arrives the end face of bellmouth step 15, now, limit fastener 13 entirety is retracted, in the crest that its limited part 131 inserts bellows 20 and the peak-to-peak groove of ripple, confined planes 131b and the crest face 21 of the limited part 131 of limit fastener 13 fit, prevent bellows 20 from moving back outward, thus complete the quick connection of bellows 20 and joint body 10.
With reference to Fig. 6, joint body 10 of the present invention can also adopt bend pipe tools, can certainly apply in other bellows 20 connection pipe fittings, reaches the object connecting bellows 20 fast.
