Technical field

The present invention relates to a kind of fitting structure, especially a kind of semi-rigid quick assembling pipe fitting knot for tube body connection Structure belongs to pipe fitting technical field.

Background technique

In recent years, with the continuous improvement of compatriots' living standard, people also increasingly pay attention to healthy and safe problem.No Rust molten steel pipe possess it is corrosion-resistant, durability is high, the distinguishing features such as healthy, environmentally friendly, Ke Xunhuanliyong, developed in developed country It is decades, very mature.And the deficiency of the domestic consuming capacity of being limited to over and understanding, it is still used at present on a large scale Plastic pipe.As safe sexual behavior is constantly broken into the introduction and plastic tube manufacturing industry of Abroad in Recent Years " direct drinking " concept Part, stainless steel waterpipe have entered development fast traffic lane.

The connection type of stainless steel waterpipe is varied currently on the market, common are compression, clamp-press type, ring pressure type, The subseries connection side that clamping hoop type, movable joint flanged joint, socket welding type, welded type and welding are combined with tradition connection Formula.In place of these connection types come with some shortcomings: 1, being substantially rigidly connected, when environment changes, (building is certainly Right sedimentation, low level earthquake, freezing and expansion etc. in north of china in winter pipe) crack can be generated, seeped water.2, difficulty of construction is big, some are right Construction personnel's technical requirements are higher, some are harsh to site operation environmental requirement.3, manufacture is complicated, at high cost.4, it is needed when installing Want specific purpose tool.

Summary of the invention

Goal of the invention of the invention is: in view of the above problems, providing a kind of for the semi-rigid of tube body connection Quick assembling fitting structure, which has the effect of capable of thering is quick assembling and disassembly, and environmental suitability is stronger.

The technical solution adopted by the invention is as follows:

A kind of semi-rigid quick assembling fitting structure for tube body connection, including main pipe, which, which has, is used for The port of pipe is connected, multiple annular grooves is provided on the inside of main pipe, the sealing ring for sealing, position is equipped in the annular groove Be additionally provided with the mounting groove for assembling circlip in main pipe's port position, be additionally provided on pipe with the matched card slot of circlip, It further include the housing for being set in main pipe port, by the housing to guarantee the circlip effect fixed to pipe.The present invention uses Circlip can effectively limit the deformation of circlip by the design of jacket structure as locking mechanism, effective using the limitation Circlip is set to block pipe, thus realize the locking of pipe, and housing is as absolute construction, it is effective to realize quick assembling and disassembly Effect.

Further, which is extended to the endface of main pipe port by the end of main pipe.The design can be more Conducive to the assembly of circlip.

Further, supervisor's body sidewall is also provided with multiple bayonets where the mounting groove, and multiple correspondences are arranged on circlip The claw of bayonet, the claw realize assembly after bayonet and with pipe pocket matches.It is effectively ensured by the design of which The effect of circlip axially position on mounting groove.

Further, circlip internal diameter D is less than tube outer diameter Ds, and circlip internal diameter D is greater than the diameter d of card slot on pipe.This sets Meter is to guarantee that circlip can block pipe.

Further, the circlip outer diameter D r≤main pipe outer diameter D e, and main pipe's outer diameter D e and circlip outer diameter D r it Between difference be less than tube outer diameter Ds and circlip internal diameter D difference.The main purpose of the mode of the design is in circlip by pipe The activity of circlip is less than circlip and is caught in the activity in card slot when son outside tension, to guarantee by external force the case where Under still have locking effect.

Further, the housing is that spring cutting ferrule or housing are assembled by screw thread and main pipe.Based on the pipe used Body size is different, and in different calibers, used assembly method is also with being adjusted.

Further, the housing is provided with ring-shaped step, which, which is assemblied on main pipe, can ensure that assembly effect.It should The design of mode can effectively ensure that the effect of housing assembly, meanwhile, which also has blocks dust, the effect of silt Fruit.

Further, the circlip is overall structure or is more valve structures.

Further, the end of the pipe is interior receipts shape arcuate structure in order to passing through sealing ring.

Further, the card slot is arc-shaped transition structure in order to the assembly of pipe by slot bottom to two sides tube body and is torn open It unloads.

In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:

A kind of this practical new semi-rigid quick assembling fitting structure for tube body connection effectively raises pipe fitting knot The efficiency of the assembly or disassembly of structure also has fitting structure preferable practical by the matching design of circlip and housing Property, it avoids the problem that causing locking effect to be short of because finishing or severe winter water inlet freeze, to effectively raise fitting structure Usage range, promote pipe connection assembly efficiency.
