Abstract
A plug in connector of detachable type used for inserting into tubular plug in piece consists of stop spring with pliers for clamping up locking ring of tube and shell. It is featured as opening pliers to let locking ring pass pliers and closing pliers when tube is completely inserted in then engaging pliers with locking ring, extending a support piece towards outside from pliers, making said support piece be with arc shaped surface for increasing retention of support piece.
Description
Technical field
The present invention relates to a kind of joint that is used to insert the pipe of being with locking ring.
Background technique
The present invention relates to a kind of joint that is used to insert the pipe of being with locking ring.Insertion tube can be the termination of durable metal tube, for example is used for the metal tube of fuel conduit.Yet joint also can be made with rigid plastic material or other injection molded material commonly used, to be connected with usual way with hose line or pipeline.
In at present used joint, the end face of support has circular shape, to extend radially outwardly into the axle of shell.When applying a pulling force to pipe, the end face of support is right after at the internal surface of opening one example that has end face with recess.In the practical application of this joint, the confining force that general identification produces by this way is not enough to guarantee the reliable connection of fuel conduit.If apply a very high pulling force to pipe, the understanding lateral of support slips off, and disconnects thereby make to connect.
Summary of the invention
Therefore, the objective of the invention is to make a kind of this type of joint, this joint can produce the chucking power that reaches safety requirement.The present invention has realized this purpose, and wherein the end face of support radially extends to become the best angle of 25-45 degree with the plane.
Because the formed angle of end face among the present invention when applying pulling force on joint, forms wedging effect on the internal surface of recess.Pulling force is big more, and the power that support is pressed on the locking ring is big more.Therefore, the present invention can obtain above this chucking power more than pulling force twice.
According to another characteristics of the present invention, can be outward-dipping in abutting connection with the clamping surface of the gripping edge of locking ring, true dip direction is opposite with direction of insertion, thus gripping edge can be as much as possible as near pedestal near locking ring.
Description of drawings
Following with reference to accompanying drawing detailed description a preferred embodiment of the invention, accompanying drawing is:
Fig. 1 is for having the exploded view of the joint shell of corresponding assembly before installing;
Fig. 2 is the plan view of stopper spring;
Fig. 3 is the side view of same stopper spring and the part sectioned view by upper support element;
Fig. 4 one shown after the insertion tube and mounted, promptly is in the longitudinal sectional view of joint shell of the state of the power of not applying;
Fig. 5 shown with Fig. 4 on shown in identical installation, but on pipe, applied pulling force.
Embodiment
Joint shown in the drawings comprises by hard can decompose vessel shell 1 and the stopper spring 2 that plastic material is made.Can insertion tube 3 in the joint, pipe 3 has annular locking ring 4.The termination that pipe 3 can comprise the conduit of being made by rigid material maybe can be connected to joints of rigid pipes by the pipe head of making than soft material by conventional method.
With reference to the accompanying drawings 4, vessel shell 1 is made of cylinder blanket wall 5 and a cell 6, is used to receive the insert that comprises several convex shoulders.Each convex shoulder all forms a limited stopper 8 at the end of cell 6.Cylinder-shaped joint spare 7 forms extending axially of cell, is used to connect the fluid line (not shown).The starting point of cell 6 is 6 ' beginning from the first area, and the internal diameter of first area is corresponding to the external diameter of pipe 3.Second area 6 " diameter bigger, with the first area adjacency.Second area be used to insert two annular sealing strips 9, central ring 10 and isolating ring 20 than major diameter, the internal diameter of second area is also corresponding with pipe 3 external diameter.
Two complete opening opposing 11 (referring to Fig. 1) are positioned on the casing wall 5, are in insertion district, the front scope of vessel shell 1.Two recess 12 are used for inserting and fixed stop spring 2 and for above-mentioned opening 11 landscape configuration.
Stopper spring 2 (referring to Fig. 2) comprises two supporting elements 13, and supporting element has crooked outer rim.Supporting element is connected by the horizontal door bolt 14 of decomposable horizontal door bolt in its tail end, and horizontal door bolt is assembled and formed a V-arrangement.The tie point place is coated with rectangular-shaped pressure plate 15, and pressure plate is slightly narrower than the opening in the shell 11.
Supporting element 13 has the curved inner wall 16 of laying relatively, is used for engaging with it when the arc external diameter of locking ring 4 inserts.In addition, supporting element has two clamp parts 17, and clamp has arch edge, is radially to the inside.The clamp part is the clamping surface of radially telling to wrong side out 19 on the insertion surface 18 and that a side has inclination, under the insertion condition, is engaged to together after the locking ring 4 of pipe 3.Clamping surface 19 is preferably slightly outward-dipping, and is promptly relative with direction of insertion, and clamp part 17 will be as much as possible as the close locking ring 4 of close pedestal like this.
Supporting element 13 additionally provides the stayed surface 21 of an arch, and by the interior contact edge 22 of the inwall that defines this recess 12 this supporting element 13 is remained on the direction relative with direction of insertion.In the contact area, stayed surface 21, from spending to the angle α of 60 degree for a plane of radially extending outward-dipping 15 along direction of insertion read fortune, angle α is preferably 25 and spends to 45 degree.Therefore, as shown in Figure 5, when when pipe 3 applies a pulling force, stayed surface 21 is pressed on the engagement edge 22 in the direction of arrow " Z ", and promptly stopper spring is pressed on the clamp 17 more tightly.
In this preferred embodiment, interior engagement edge 22 is preferably circle.Yet interior engagement edge also can have inclined surface, and the angle of engagement edge is approximately corresponding to angle α.This measurement has greatly been simplified along the slip of stayed surface 21.
When inserting stopper spring 2 in the cell 6, supporting element 13 beginnings force together with it along the direction of arrow " P ", as shown in Figure 1.In then stopper spring 2 being inserted opening 11 on the casing wall 5 along arrow " Q ", and compression is by cell 6.In case supporting element 13 passes opening 11, because the restoring force of the horizontal door bolt 14 of elasticity just supporting element 13 expand into its original state, and enters recess 12, as original, arrive the center of cell 6, to obtain axially support until it.
In the process of insertion tube 3, between horizontal door bolt 14 and recess 12, need to keep enough spaces, so that allow supporting element 13 to form lateral bending.In case locking ring 4 slips over and inserts surface 18 in the process that pipe 3 inserts, above-mentioned situation will take place automatically, and at this moment clamp part 17 just can be to external pressure.When pipe 3 touched the stopper 8 of cell 6, supporting element 13 just bounce back into its original state, and clamp 17 is positioned at the rear portion of locking ring 4, and locking ring is pressed on the clamping surface 19, has been fixed in the joint thereby will manage 3.
When separating joint, pressure plate 15 forces together, and fully separates up to clamp part 17, and promptly clamp part 17 no longer meshes in locking ring 4 back.At this moment just pipe 3 can have been extracted from receive shell like a dream.
