Description
Technical field
The utility model relates to pipe joints such as a kind of water route, gas circuit or oil circuit, refers to a kind of self-locking quick quick coupling especially.
Background technique
In industrial every field, in all conglomeraties such as bathrooms, usually can relate to the connection of two pipelines (this pipeline can be water route, gas circuit or oil circuit or the like), pipe fitting joint is exactly a kind of connection fittings that are widely used between pipeline and the pipeline.Traditional pipe fitting joint usually adopts and is threaded, and installs that difficulty, setting tool are difficult looks for, seals problems such as unreliable yet be threaded but to exist, and must spend the more time when installing can screw tight especially at every turn.At present also have the different rapid pipe joint of many types structure, but there is the dismounting inconvenience in existing rapid pipe joint, comes off easily, defective such as compressive strength is not enough, and tightness is bad.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of operation quicker, faster, simple in structure, and connects safer self-locking quick quick coupling.
For solving the problems of the technologies described above, technical solution of the present utility model is:
A kind of self-locking quick quick coupling comprises first joint and second joint that are connected with two pipelines respectively; The end outside that described first joint inserts within second joint is provided with groove; The end that described second joint and first joint are pegged graft mutually is provided with a slot radially, this radially is inserted with an annular inserted sheet that can engage with above-mentioned groove in the slot, this inserted sheet one end is formed with one and is positioned at outside second joint by sheet, should be by being provided with elastic component between the sheet and the second joint exterior edge face; This inserted sheet and radially be provided with the limit structure that can prevent that inserted sheet from deviating between the slot.
Described limit structure is to be separately positioned on the radially slot of second joint and draw-in groove and the fixture block on the inserted sheet.
The described draw-in groove length that extends back forms guide groove.
The side upper end that described inserted sheet differs from by sheet is formed with guide face.
One one-way valve of being made up of spool and spring is set within described first joint or second joint, and the one-way valve of one of them joint is subjected to replacing of another joint and opens.
After adopting such scheme, because the utility model is provided with an annular inserted sheet that can move radially on second joint of rapid pipe joint, when inserting first joint in second joint, first joint pushes against annular inserted sheet and it is stepped down, when the groove of first joint is relative with this inserted sheet, inserted sheet resets and is stuck in the groove of first joint, thereby makes the firm connection of two joints; And when splitting, only need press inserted sheet by sheet, inserted sheet stepped down once more and break away from the groove of first joint, first joint can be extracted this moment, reach the purpose of fractionation.This rapid pipe joint only needs a step can reach the also purpose of self-marketing of connection when mounted, and fractionation also only need be pushed by sheet and be extracted two steps of two joints, therefore is that installation or fractionation are all very quick, and more simple and reliable.And this rapid pipe joint accessory is few, simple in structure.
In addition, the utility model is provided with one-way valve in a joint or two joints therein, and one-way valve can be closed joint from horizontal reset when splitting, thereby can prevent effectively that fluid, gas are not stressed when partition and leak, and order is used safer.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
What the utility model disclosed is a kind of self-locking quick quick coupling, to shown in Figure 6, is preferred embodiment of the present utility model as Fig. 1.Described rapid pipe joint comprises first joint 1 and second joint 2 that is connected with two pipelines respectively.Wherein:
The end outside that described first joint 1 inserts within described second joint 2 is provided with Sealing 11, also is provided with groove 12.
As shown in Figure 2, the end that described second joint 2 and first joint 1 are pegged graft mutually is provided with a slot 21 radially, this radially is inserted with an annular inserted sheet 3 in the slot 21, these inserted sheet 3 one ends are formed with one and are positioned at outside second joint 2 by sheet 31, should be by being provided with an elastic component 4 (this elastic component can be spring) between sheet 31 and second joint, 2 exterior edge faces, described inserted sheet 3 and radially be provided with the limit structure that can prevent that inserted sheet 3 from deviating between the slot 21.Described limit structure can be multiple structure, and this limit structure of embodiment described in the figure comprises the draw-in groove 22 that is arranged on described radially slot 21 1 sides and is arranged on the fixture block 32 that cooperates with draw-in groove 22 on the described inserted sheet 3.When described inserted sheet 3 and 2 assemblings of second joint, inserted sheet 3 is inserted in the described radially slot 21 from the side that elastic component 4 is set, again elastic component 4 is arranged between the exterior edge face of the contact pin 31 and second joint 2, continue to push inserted sheet 3, the fixture block 32 of inserted sheet 3 is stuck in the draw-in groove 22 in the slot 21 radially, thereby inserted sheet 3 is limited in radially in the slot 21, prevent that it is from radially deviating from the slot 21, and this inserted sheet 3 is when normality, and its inner ring differs from the endoporus that stretches into second joint 2 by a side of sheet 31.This inserted sheet 3 differs from by a side of sheet 31 upper end and is formed with guide face 33 in addition.
One one-way valve of being made up of spool 71 and spring 72 7 can be set within described first joint 1 and second joint 2, and wherein stretch out outside the end that first joint 1 and second joint 2 plug under normal conditions first joint, 1 interior spool 71 outer ends.
The installation process of rapid pipe joint described in the utility model is: as Fig. 3, shown in 4, the end that described first joint 1 is had groove 12 inserts within the end that second joint 2 has inserted sheet 3, when the end face of first joint 1 touches the guide face 33 of inserted sheet 3, under the guiding of guide face 33 that inserted sheet 3 is moving to a thruster that differs from by sheet 31, thereby can make first joint 1 continue to insert, when the groove 12 of first joint 1 and this inserted sheet 3 are relative, inserted sheet 3 resets under the effect of elastic component 4, the endoporus bottom surface of inserted sheet 3 is stuck in the groove 12 of first joint 1, as Fig. 5, shown in 6, thereby make first joint 1 and second joint 2 form firm coupled condition.Meanwhile, the one-way valve spool in first joint 1 compresses the one-way valve spool in second joint 2, makes two one-way valves 7 all be opening state, thereby liquid or gas are flow through in rapid pipe joint.
Described rapid pipe joint is pushed describedly by sheet 31 when splitting, and makes inserted sheet 3 to a side shifting that differs from by sheet 31, and the endoporus bottom surface of inserted sheet 3 breaks away from the groove 12 that fastens first joint 1, can extract first joint 1 in addition, makes two joints separately.In addition, after rapid pipe joint split, the one-way valve 7 in two joints can prevent effectively that fluid, the gas in the pipeline is not stressed and leaks from horizontal reset when partition, use safer.
In addition, also one-way valve can be set within described two joints, perhaps only in a joint one-way valve be set, end or the interior ladder surface by another joint reaches the purpose of replacing spool and making one-way valve open then.
Need to prove that the draw-in groove 21 of the described limit structure length that can extend back forms guide groove, the fixture block 32 of inserted sheet 3 is only moved, so this guide groove can play the guiding role to inserted sheet 3 in guide groove.In addition, the draw-in groove of described limit structure and the position of fixture block can be provided with arbitrarily, all do not influence normal use.
