Abstract
The utility model relates to a connecting pipe. A three-way connecting pipe consists of three pipe sections communicated with each other at inner ends. Quick joints are arranged at the external ends of the three pipe sections. The quick joint comprises a pipe end part, a seal ring, a circular installation head and a lock catch connected integrally with the external ends of the pipe sections. The seal ring is installed inside the pipe end part. The orifice of the pipe end part is an anti-falling opening of which the internal diameter is reduced from inside to outside. The circular installation head is installed on the anti-falling opening, that is, the external end part of the circular installation head is located outside the anti-falling opening, and the internal end part of the circular installation head extends into the inside of the anti-falling opening. A plurality of arc-shaped locking heads corresponding to the anti-falling opening are arranged on the inner side wall of the circular installation head. The plurality of arc-shaped locking heads are located in the anti-falling opening and cannot be separated. Metal strips are arranged on the inner side wall of the arc-shaped locking heads. The lock catch is located outside the anti-falling opening and is locked on the external end part of the circular installation head. The three-way connecting pipe provided by the utility model has the advantages that the three-way connecting pipe is novel in structure, can replace threaded connection, and conveniently and quickly connect the pipeline and be detached in the pipeline, and is high in efficiency and good in effect.
Description
Technical field
The utility model relates to a kind of connection pipe fitting.
Background technique
Existing three-limb tube, the pipeline section that is interconnected by three the inners connects and composes, and the outer end of three pipeline sections is respectively equipped with internal thread or outside thread, and this three-limb tube structure is single, needs swivel tee pipe or external pipeline during connection.And many times three of three-limb tube external port need be docked at the fixed position; Can not arbitrarily rotate, therefore make each parts of pipe-line system just can be overlapped to form in order, connect very loaded down with trivial details; Efficient is low, after connecting individual components dismounting maintenance is bothered very much.
Summary of the invention
The goal of the invention of the utility model provides a kind of novel structure, all convenient and three-limb tube fast of connecting pipeline and dismounting.
In order to realize the foregoing invention purpose, the utility model has adopted following technological scheme:
A kind of three-limb tube, the pipeline section that is interconnected by three the inners connects and composes, and the outer end of three pipeline sections is equipped with rapid pipe joint; Said rapid pipe joint comprises tube end, seal ring, circular mounting head and the snap close that the outer end with pipeline section is connected as a single entity, and seal ring is installed in the tube end inboard, and the mouth of pipe of tube end is the anticreep mouth that internal diameter dwindles from the inside to the outside; The circular mounting head is installed on the anticreep mouth, and promptly the outer ends of circular mounting head is in the anticreep mouth outside, and it is inboard that inner end extends the anticreep mouth; Circular mounting head the inner is provided with a plurality of arc dops corresponding with the anticreep mouth, and a plurality of arc dops are in the anticreep mouth to deviate from, and the madial wall of arc dop is provided with the metal card article; Snap close is in the anticreep mouth outside and is stuck in the outer end of circular mounting head.
As preferably, said arc dop quantity is between 3-7.
Adopted the three-limb tube of technique scheme, the outer end of three pipeline sections is equipped with rapid pipe joint, and rapid pipe joint comprises tube end, seal ring, circular mounting head and the snap close that the outer end with pipeline section is connected as a single entity; Take off snap close, insertion needs the connecting tube of connection, and connecting tube runs through circular mounting head and seal ring; Retract the connecting tube clamping again, lock snap close and accomplish connection, quick and convenient; Substitute and be threaded the joint efficiency height.Therefore the advantage of this three-limb tube is: novel structure, substitute and be threaded, connecting pipeline and in pipeline dismounting all convenient and fast, efficient is high, and is effective.
Description of drawings
Fig. 1: the utility model embodiment's cross-sectional view.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
A kind of three-limb tube as shown in Figure 1, the pipeline section 1 that is interconnected by three the inners connects and composes, and the outer end of three pipeline sections 1 is equipped with rapid pipe joint 1a, and the size of three rapid pipe joint 1a is all identical with shape.Rapid pipe joint 1a comprises tube end 13 that the outer end with pipeline section 1 is connected as a single entity, seal ring 12, circular mounting 10 and snap close 11.Seal ring 12 is installed in tube end 13 inboards, and the mouth of pipe of tube end 13 is anticreep mouths 131 that internal diameter dwindles from the inside to the outside, and the internal diameter at tube end 13 mouth of pipe places specifically is that linearity is dwindled, and anticreep mouth 131 is tapered.Circular mounting 10 is installed on the anticreep mouth 131 of tube end 13, and promptly the outer ends of circular mounting 10 is in anticreep mouth 131 outsides, and inner end extends anticreep mouth 131 inboards.Circular mounting 10 the inners are provided with a plurality of arc dops corresponding with anticreep mouth 131, and circular mounting 10 outer end are circular mounting rings 102, and promptly circular mounting 10 is connected as a single entity by a plurality of arc dops 101 of the circular mounting ring 102 of outer end and inner end and constitutes.Corresponding and the circumferential array of the madial wall at a plurality of arc dops 101 and anticreep mouth 131 places ringwise, a plurality of arc dops 101 are in the anticreep mouth 131 to deviate from.Be equipped with metal card article 101b on a plurality of arc dop 101 madial walls, metal card article 101b specifically is the curved metal bar that matees with arc dop 101 madial walls.Snap close 11 is in anticreep mouth 131 outsides and is stuck in the outer end of circular mounting 10.
During installation, earlier snap close 11 is taken off, the connecting tube with the outside inserts from tube end 13 again, runs through circular mounting 10 and seal ring 12 successively.When passing metal card article 101b, above-mentioned a plurality of arc dop 101 radially outward elasticity are opened.Then run through seal ring 12 and accomplish sealing.The rollback connecting tube makes metal card article 101b tighten the connecting tube outer side wall again, and outwards the open arc dop 101 of elasticity tightly is stuck on the anticreep mouth 131, and the rollback stroke is big more, just on anticreep mouth 131, blocks tightly more.Snap close 11 is stuck on the circular mounting 10 in anticreep mouth 131 outsides and makes the outer end of connecting tube and three pipeline sections 1 be connected firmly, and can not deviate from again.
The quantity of above-mentioned arc dop 101 is preferably between 3-7.Quantity is less than 3, connects low precision and insecure; Quantity is during far more than 7, and cost of production is very high.
