self-locking high-pressure rubber pipe assembly that the utility model provided compared with prior art has the following advantages; One of which; Because constituting the pipe joint of this self-locking high-pressure rubber pipe assembly is made up of lock ring, overcoat and the locknut that the core pipe that can insert said high-pressure rubber pipe, some lock lobes constitute; And need not to use special pipe locking machine when assembling high-pressure rubber pipe and pipe joint, can realize the assembled on site and the maintenance of pipe assembly, practice thrift user cost and maintenance cost greatly; They are two years old; The joint of sebific duct forms curved shape by the lock ring chucking that the some peripheral annular convex-concave annular grooves and the some lock lobes that are arranged on the core pipe pipe linkage section outer wall constitute in this self-locking high-pressure rubber pipe assembly structure; Improved the join strength of sebific duct and self-locking high-pressure rubber pipe assembly greatly, can satisfy manifold and in the high pressure Environmental Conditions of 35～140Mpa ~ 320Mpa, not take off a requirement; Its three, high-pressure rubber pipe and pipe joint that this self-locking high-pressure rubber pipe is particularly suitable for high tenacity, thick tube wall connect and compose self-locking high-pressure rubber pipe assembly.
Description of drawings
The structural representation of the self-locking high-pressure rubber pipe assembly that Fig. 1 provides for the utility model;
Fig. 2 is for constituting the nut structure schematic representation of above-mentioned self-locking high-pressure rubber pipe assembly;
Fig. 3 is for constituting the structural representation of above-mentioned self-locking high-pressure rubber pipe assembly lock ring.
Embodiment
explain further details below in conjunction with the structure and the use principle of the self-locking high-pressure rubber pipe assembly that accompanying drawing provides the utility model.
be illustrated in figure 1 as that the utility model provides by the link together structural representation of the self-locking high-pressure rubber pipe assembly that constitutes of pipe joint and high-pressure rubber pipe 10.The structure that constitutes this pipe joint is provided with the locknut 5 that core pipe 2, its end of being preferably bulge loop (also can be the projection ring that projection at interval constitutes) 1 and can inserting high-pressure rubber pipe 10 can be stuck in the cylindrical jacket 4 of the lock ring 3 that is made up of eight lock lobes on the above-mentioned bulge loop 1, suit lock ring and be used for fixing this overcoat by the middle part and constitutes.
With bulge loop or projection ring 1 is that the boundary is divided into the core pipe connecting end 6 and the pipe linkage section 7 that inserts high-pressure rubber pipe 10 ends formation pipe joint assembly that is used to connect other pipe fittings; Axially be provided with three (or a plurality of) convex annular concave ring groove 8 structures at above-mentioned core pipe pipe linkage section outer wall, and be plugged in the high-pressure rubber pipe 10 end steel wire casing plies 11 of having removed outer glue-line 9 and inner glue layer 12 along circumference;
are provided with the end madial wall groove 13 and axially are provided with and manage the lock ring 3 that forms steel wire casing ply 11 on bulge loop or the projection ring 1 that corresponding eight lobes along peripheral annular convex-concave annular groove 14 of linkage section outer wall (can be arranged to three lobes, pintongs or six lobes according to the size of caliber) locks lobes 15 (as shown in Figure 3) are connected to the core pipe along it.It axially is divided into the thin and thicker two-stage structure of ring wall by the lock ring that constitutes of lock lobe, promptly makes lock ring and the spacing of managing 7 of linkage sections by thin thickening.To be inserted in wherein steel wire casing ply 11 chuckings than light filling bar A by concavo-convex annular groove of interlaced lock ring and the concavo-convex annular groove of managing on the linkage section in spacing; Steel wire casing ply 11 chuckings that will not have attenuate at thicker section B of spacing through less concavo-convex annular groove.The end is provided with threaded cylindrical jacket 4 and is sleeved on outside the lock ring, and the locknut 5 (as shown in Figure 2) of ring 16 is screwed with cylindrical jacket 4 screw threads and is connected in being provided with.
In the structure of above-mentioned self-locking high-pressure rubber pipe assembly:
