Embodiment
Fig. 1 illustrates the exploded view of a connection set.This connection set is made up of a main body 1, and this main body 1 is basic for cylindrical and have two part 2a, 2b, these two- part 2a, 2b with respect to the perpendicular plane symmetry of the longitudinal axis of described main body 1.Cylindrical bearing surface 4, the first circular groove 4a that the 2a of first portion that follows this longitudinal axis to this connection set middle body from the outer end has inlet inclined-plane (chamfer) 3 and an end are disposed in this supporting surface 4.
The 2a of this first portion runs through a truncated cone chamber 5, and this truncated cone chamber 5 is limited by a convex shoulder 6 than the part of big base, and it is positioned at the position towards these connection set central authorities.One longitudinal rib 7 also stretches to the inside of this truncated cone chamber 5.
Then, this convex shoulder 6 extends by a central cylindrical shape supporting surface, also is provided with the second circular groove 8a in this supporting surface.This central cylindrical shape supporting surface 8 ends at an annular central rib 9, and this rib 9 is opened two-part 2a and the 2b branch of this cylinder-shaped body 1.These two- part 2a, 2b have a kind of symmetrical structure.Connection set of the present invention also has O-ring seal 10, and it is contained in interior groove 4a and the 8a.This connection set of the present invention also has a trip ring 11 that is positioned at each truncated cone chamber 5.Near opening, this trip ring 11 has two opposite end 11a, the 11b that is bearing on the longitudinal rib 7, thereby makes that described trip ring 11 can be along described longitudinal rib 7 longitudinal sliding motions, and with respect to the described trip ring 11 of the twist-lock of this main body 1.Therefore, this ring 11 longitudinal axis y-y ' along this connection set in truncated cone chamber 5 freely locatees.When it moves or along the direction opposite with direction of engagement when moving, its position this truncated cone chamber 5 in is only definite by the end of a pipe 20 along direction of engagement in this connection set.Thereby, main body 1 or more precisely the rotation of this connection set this trip ring 11 is rotated.Push end 11a and 11b more or less open and can advantageously expand this trip ring 11, when inserting a pipe 20 in these connection sets and coming to this during by this trip ring 11.
For example, this trip ring 11 is made by a kind of plastics or metallic material, and the elasticity of this material allows this ring 11 originally for should not press or not have deformation state, and its inner diameter is less than the outer diameter of pipe 20 under this state, thereby in the time of in being inserted into described device, its elastically deformable is also clamped described pipe 20.
On the outer end, this main body 1 can have outside longitudinal rib 1a, 1b, and this rib 1a, 1b are designed to make this connection set to be easier to catch and handle.This with regard to be easier to or instrument that need not be special manually rotate connection set of the present invention.
Advantageously, this main body 1 has a middle section that especially possesses resistivity, this middle section thickness between truncated cone chamber 5 increases, and external rib 1a can reinforce this main body 1 longitudinally simultaneously, and it can resist for example high pressure of 50 crust (bar) orders of magnitude in a given embodiment.
Because main body 1 is to make by for example minute surface welding (mirror soldering) two and half shells, this two and half shell for example obtains by the injection of plastic material, therefore can produce burr along the separating surface of described half shell.These burr can not influence the displacement of trip ring 11 in truncated cone chamber 5 like this, and described trip ring 11 has two along the relative vertical hole 13 of diameter, and it is positioned on this separating surface to eliminate any potential fixing or clamping stagnation problem.
In one embodiment, this main body 1 is made up of two identical moulded half.For the purpose of assembling, one of them half shell has the second truncated cone chamber 5 of a longitudinal rib 7 along pivoting 180 ° perpendicular to of longitudinal axis y-y ' with formation.Therefore, each half shell only has a longitudinal rib 7 (for example Fig. 1).
Advantageously, trip ring 11 has a circumferential surface 14 that protrudes.This circumferential surface 14 for example has the curve of a ball-type, makes that described ring 11 can be fastened and can not be stuck in this truncated cone chamber 5.Described trip ring 11 is done length travel by rib 7 longitudinally can be fastened significantly, and this longitudinal rib 7 is from being the big taper pedestal of convex shoulder 6 forms.
Fig. 6 and 7 shows another embodiment of ring 11.Fig. 7 is the schematic representation along arrow F among Fig. 6.Ring 11 has the cannelure 14a that extends at its partial-length from an end 14b.This groove 14a entirely encircles 11 radial thickness across this, and the outside on an end 14b is opened wide.Groove 14a is radially direct in such a way,, limits on end 14b one side one group radially tongue piece 14c that is.Thereby, each radially tongue piece 14c just limit by a pair of groove 14a.All radially tongue piece 14c have been connected from partial-length facing to this ring 11 of the other end 14d of end 14b.Thereby, make this encircle 11 utmost points and be suitable for slight deformation or oval-shaped pipe owing to this groove 14a and the radially existence of tongue piece 14c.Thereby groove 14a and radially tongue piece 14c be easier to pipe 20 is inserted in the ring 11, particularly when described pipe 20 has a part of not really justifying.
Fig. 2 illustrates the sectional view of connection set of the present invention, and on the left side wherein, the trip ring 11 that promptly is positioned at part 2a be against convex shoulder 6 supportings, and is supported on the longitudinal rib 7.In part 2b, blend shows as a kind of shape of pipe 20, and this pipe 20 is bonded in this connection set, is bonded on or rather in the part 2b.Pipe 20 is engaged, and ends at the convex shoulder that forms central annular rib 9, thereby crosses this trip ring 11.Thereby this trip ring 11 is pushed open a little, and leans against or near the inwall 5a of truncated cone chamber 5.Therefore, the outer circumference surface 14 of this trip ring 11 moves towards the tapering part of truncated cone chamber formation.When managing 20 when being inserted in this connection set, push trip ring 11 open, cause internal thread 12 to begin to be embedded in the material of forming described pipe 20.The internal thread 12 of trip ring 11 for example has a triangle that acute angle arranged or rectangle part forming helical recesses, and this helical recesses stops this pipe 20 to be drawn out when described internal thread 12 is embedded in pipe 20 peripheral.
For example, this internal thread 12 example is shown among Fig. 3.
Fig. 4 illustrate use that this connection set finishes between two pipes 20 a kind of connection.Fig. 4 illustrates a kind of connection of using the fixed tube 20 that this connection set finally finishes.Traction is moved every pipe 20 and just trip ring 11 can be moved to the outside slightly, like this cooperating between the inwall 5a by truncated cone chamber 5 and the outer surface 14, can retighten them around managing 20.
This has just increased the mosaic of helical recesses 15 in the material of forming pipe 20, has finally caused managing 20 the fully locking of end in this connection set.
Connection set of the present invention has been arranged, and pipe 20 end still is held in place in the zone between truncated cone chamber 5 being subjected to the mild traction motion back (see figure 4) that is used to lock, promptly in the reinforcing area.
Fig. 5 illustrates along the sectional view of Fig. 4 center line V-V.
By being parallel to longitudinal axis y-y ' end of described pipe 20 is assembled together, has just connected two pipes, 20 (see figure 2)s.Rotate main body 1 along the direction opposite, they are stopped against central annular rib 9 with disengaged direction.This is by main body 1 rotational motion is finished little by little to unclamp pipe 20 end by internal thread 12.Because longitudinal rib 7 can make trip ring 11 rotate, so this is possible.Thereby will manage the outside that 20 end is pushed this connection set to simultaneously.Because the internal thread 12 on two trip rings, 11 opposite directions, they break away from after main body 1 is rotated multi-turn fully.
Connection set is to link to each other with the end of pipe 20 like this, promptly potentially since pipe 20 with respect to ring 11 relatively rotate, every termination of pipe 20 is combined in the corresponding ring 11, then, apply tractive force and be displaced in the truncated cone chamber 5 managing 20 at joint end, be fixed in addition on the pipe 20 will encircle 11.
Connection set of the present invention can be used for connecting the pipe of being made by a kind of plastic materials, for example high density polyethylene (HDPE) (HDPE), polypropylene (PP) or PVC (PVC).Connection set of the present invention has the advantage that does not need any specialist tools just can be removed.Manual teardown is fine certainly, without any problem.In addition, to connect without special pre-treatment be necessary in pipe 20 end.This connection set also has big mechanical resistance, and can not increase the needs to the space.Therefore shown that fully automatic location machinery is operable.
Because can connect two pipes 20 as quick as thought, and do not change a kind of like this reliability of connection, so connection set of the present invention has caused people's attention.In fact, the existence of central annular rib 9 can show how far a kind of like this connection could be satisfactory if need being inserted the end of pipe 20 to the user.Therefore, the end of this pipe 20 engages with backstop on the described end that heads on central annular rib 9.
In addition, vertically cylindrical bearing surface 4 and 8 can should manage 20 by longitudinal guide, and their relatively large diameters can provide a kind of sealing simultaneously, have high radius of curvature even if form the unit of pipe 20 and this connection set.Seal ring 10 for example O-ring seal can provide the sealing of cooperating mutually with supporting surface 4 and 8.
Especially, the seal ring 10 that is positioned at the circular groove 1a of overhang bracket face 4 can obtain to be used for the progressive radius of curvature of the pipe 20 that connected, keeps the sealing of described pipe 20 simultaneously and delays to occur " straw effect " simultaneously.
The shape of this connection set, the truncated cone of main body 1 also can make it be used for one pipe more precisely, and this has superiority especially.
Therefore, not hard to imagine its use is buried on the machine of putting at single tube and multitube.
