Description

A kind of insertion type quick coupling structure

The utility model relates to pipeline and connects class, particularly a kind of insertion type fast connector structure.

As everyone knows, the normal pipe joint that uses does not all break away from the lock of joining of lock nut, however with the lock of joining of lock nut, often because locking strength is difficult for being affectedly bashful or situation such as builder's carelessness under, and easily produce the shortcoming of becoming flexible; Especially pipe joint of joining lock with lock nut commonly used, all be the strength of compeling to close entirely, make to be engaged in and take in the head that its engaging force is then comparatively weak virtually by the distortion generation of cushion rubber, in case building has it to vibrate powerful external broach, broken pipe is promptly arranged or takes off pipe to produce; Secondly make that sealed tool is difficult can operate because construction runs into obstruction of surrounding environment often, add the real difficult complete sealed enforcement of locking screw, making the construction assembling slow and be difficult to walk virtually, this is that the most normal construction run into of joint pipe structure is perplexed.

The purpose of this utility model is exactly all shortcomings at the pipe joint existence of above-mentioned normal use, and a kind of insertion type quick coupling structure is provided.

The technical solution of the utility model:

According to the purpose of this utility model, a kind of insertion type quick coupling structure is provided, whole structure is mainly by adapter, pad, elements such as leak-stopping cushion rubber,  shape inserts and main nipple are formed, wherein be provided with the caulking groove of four equalizations at the apical margin of the joint end of main nipple, have a retaining edge in the main nipple, can keep off and close the leak-stopping cushion rubber and the pad of inserting earlier; And taking over the suitable length place, give first roll extrusion one annular groove;  type inserts is provided with the symmetrical portion of closing that supports for being a  font shape in its face, supports the portion of closing and then is the squint shape, when being beneficial to be intercalated in the caulking groove of main nipple, closes the source point with joint efforts that supports that presses down pad and leak-stopping cushion rubber as supporting; When  type inserts penetrates caulking groove in main nipple, then be pressed against pad and the leak-stopping cushion rubber makes it compel to close in adapter by inserts, and  type inserts runs through main nipple and during corresponding to the subtend caulking groove, just can schedule and take over by the inner arc groove embedding of  type inserts, make to form the embedding of leak-stopping cushion rubber in the adapter, reach the fixed rapid construction effect of dual embedding under the pressure of taking over outer and making  type inserts build-in be positioned to take over.

The utility model is a kind of insertion type quick coupling structure, with a kind of no locknut compacting structure, reaches and strengthens outside the anti-strong high pressure of joint end, also has conveniently, advantage such as simple and easy, quick joint.

(1) for take over, (11) be annular groove, (2) for pad, (3) for leak-stopping cushion rubber, (31) for groove shape, (4) for  type inserts, (41), (42) for hoop close internal diameter, (43), (44) for support the portion of closing, (431), (441) for tilted guide surface, (5) for main nipple, (50) for retaining edge, (51) for caulking groove, (501) for keeping off pipe portion.

As accompanying drawing 1 to shown in the accompanying drawing 9, overall structure is mainly by taking over (1), pad (2), leak-stopping cushion rubber (3),  type inserts (4) and main nipple elements such as (5) are formed, wherein main nipple (5) apical margin that lies in each joint end is provided with the caulking groove (51) of four equalizations, then have a retaining edge (50) in the main nipple (5), can keep off closing and be taken up in order of priority the leak-stopping cushion rubber (3) and the pad (2) of inserting; Shown in accompanying drawing 3 and accompanying drawing 4, main nipple (5) prolongs the below appropriate depth of tool retaining edge (50) in its joint end, protrude out the retaining pipe portion (501) of several local crosscuts by inner tubal wall, with can be after taking over (1) and inserting, be positioned best depth of engagement and retaining and close, reach the facility of installation in the root edge of taking over (1); Shown in accompanying drawing 5 and accompanying drawing 6,  type inserts (4) is a  font shape, central authorities are provided with the twice hoop and close internal diameter (41), (42), wherein Wai Ce hoop closes internal diameter (42) and closes internal diameter (41) for big than the inboard hoop slightly, and be provided with to the portion of closing (43), (44), and prolong these the portion (43), (44) direction of insertion of closing that support in the forward and backward side of its face, form tilted guide surface (431), (441), be beneficial to importing and plug together; As shown in Figure 7, when  type inserts (4) is in the caulking groove (51) that is not inserted in main nipple (5) fully, then can close internal diameter (42) and pass through to put to insert and take over (1), and will take over (1) location and retaining closes in keeping off in the pipe portion (501) by the outside of  type inserts (4) hoop; In adapter (1), roll and establish an annular groove (11), and the external diameter of this annular groove (11) just can close internal diameter (41) institute build-in by the inboard hoop of inserts (4); As shown in Figure 8, in case when  type inserts (4) plugged together fully in the caulking groove (51) of main nipple (5), embedding was fixed fully to be about to take over the annular groove (11) of (1); When this external  type inserts (4) plugs together in the caulking groove of main nipple (5), begin to press on pad (2) and cushion rubber (3) to closing portion (43) via the importing of tilted guide surface (431) before also making simultaneously, make it produce the downforce source of whole property, and the  type inserts (4) of full wafer imports via supporting the tilted guide surface (431) that closes portion (43), (44), promptly can penetrate fast in caulking groove (51), make in adapter (1) formation and compeled to close by leak-stopping cushion rubber (3), by the embedded fixed position of  shape inserts (4), reach the fixed rapid construction ability of dual embedding outward; Again as shown in Figure 9, pad (2) of inserting in the main nipple (5) and the formed height of cushion rubber (3), just should be positioned at the high scope of groove of caulking groove (51), except that should keep  shape inserts (4) can the permission line of rabbet joint of big vast intercalation, and still give and stay suitable allowing to compress the variable height space, can after intercalation, compel to close in leak-stopping cushion rubber (3), compel to close effect with leak-stopping cushion rubber (3) in forming in pipe fitting (1); In addition, the inner edge surface of leak-stopping cushion rubber (3) is designed to the groove shape (31) of reverse buckling type, has the advantage of the sincere adapter of more powerful embedding (1), does not deviate from.

Be depicted as embodiment of the present utility model as accompanying drawing 10 and accompanying drawing 11, main nipple of the present utility model (5) can implement to be used for curved head type structure, straight formula type structure or three-way type structure.

The utility model is simple in structure, and is easy to use, quick, also have can reach engage leakproof, Take over and not deviate from, and can bear the advantage such as high Oscillating Coefficients.
