Abstract
The utility model relates to a connecting pipe fitting. A reducing adapter pipe consists of a reducing pipe body and two quick joints. The quick joints are arranged at the two ends of the reducing pipe body, and have the same shape and different sizes. Each quick joint comprises a pipe end part integrated with the end part of the reducing pipe body, a sealing ring, a round mounting heat and a buckle. The sealing rings are arranged on the inner sides of the pipe end parts. A pipe orifice of each pipe end part is an anti-separation opening of which the internal diameter is decreased from inside to outside. The round mounting heads are arranged on the anti-separation openings, namely the outer end parts of the round mounting heads are positioned outside the anti-separation openings, and the inner end parts of the round mounting heads are extended to the inner sides of the anti-separation openings. Four annular chucks opposite to the corresponding anti-separation opening are arranged at the inner end of the corresponding round mounting head, are positioned in the anti-separation opening, and cannot be separated. Metal clamping strips are arranged on the inner sidewall of the annular chucks. The buckles are positioned outside the anti-separation openings, and are clamped on the outer end parts of the round mounting heads. The reducing adapter pipe has the advantages of novel structure, high efficiency and good effects; and threaded connection is replaced, a pipeline can be conveniently and quickly connected, and the reducing adapter pipe in the pipeline can be conveniently and quickly disassembled.
Description
Technical field
The utility model relates to a kind of connection pipe fitting.
Background technique
Reducing body on the existing reducing transfer tube is to be connected as a single entity by two sections bore pipeline sections inequality to constitute, and the two ends of reducing body are equipped with screw thread, generally is internal and external threads accordingly.Existing reducing transfer tube is through being threaded, and structure is single, need tie up raw meal belt during connection, and connection is very loaded down with trivial details, and efficient is low.
Summary of the invention
The goal of the invention of the utility model provides a kind of novel structure, need not tie up the raw meal belt that waterproof is used, and connects the pipeline of reducing and all convenient and reducing transfer tube fast of dismounting in pipeline.
In order to realize the foregoing invention purpose, the utility model has adopted following technological scheme:
A kind of reducing transfer tube; By the reducing body be located at reducing body two ends, shape is identical and two rapid pipe joints varying in size constitute; Each rapid pipe joint includes tube end, seal ring, circular mounting head and the snap close that is connected as a single entity with the reducer pipe end of body; 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 4 the arc dops corresponding with the anticreep mouth, and 4 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.
Adopted the reducing transfer tube of technique scheme, by the reducing body be located at reducing body two ends, shape is identical and two rapid pipe joints varying in size constitute, rapid pipe joint includes tube end, seal ring, circular mounting head and the snap close that is connected as a single entity with the reducer pipe end of body; 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 reducing transfer tube is: novel structure, substitute and be threaded, connecting pipeline and in pipeline dismounting all convenient and fast, efficient is high, and is effective.

Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
A kind of reducing transfer tube as shown in Figure 1, by reducing body 1 be located at reducing body two ends, shape is identical and two rapid pipe joint 1a varying in size constitute.Each rapid pipe joint 1a includes the tube end 13 that is connected as a single entity with reducing body 1 end, 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 4 the 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 4 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 4 arc dops 101 and anticreep mouth 131 places ringwise, 4 arc dops 101 are in the anticreep mouth 131 to deviate from.Be equipped with metal card article 101b on 4 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 4 arc dops, 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.
