Abstract
The utility model relates to a quick compression-type joint which is made from the plastics. The quick compressible joint is characterized in that the joint comprises a joint main body with central holes; the central holes at the two ends of the joint main body are sequentially sleeved with a sealing ring, a fixing ring and a fastening part from the inside to the outside; the inner diameters of the sealing ring, the fixing ring and the fastening part are basically same; the outer surfaces of the two ends of the joint main body are respectively provided with a screw cap; and the fastening part is fastened by the screw caps. The inner diameter of the central hole of the joint main body, the inner diameters of the fixing ring and the fastening part, and the outer diameter of a pipe material are accordant with each other. After the connecting pipe material is inserted, the screw caps are tightly screwed to extrude the fastening part and the fixing ring, so that the pipe material is tightly held, and the sealing ring is completely contacted with the pipe after being extruded to achieve a sealing function. Therefore, the quick compressible joint is simple in structure and reliable in sealing, and can be disassembled for repeated use.
Description
Technical field
The utility model relates to a kind of pipe coupling, relates in particular to a kind of plastic pipe rapid pipe joint.
Background technique
As the joint between pipeline and the pipeline, adopt two kinds of forms at present mostly, the one, flange connects, and the 2nd, electricity consumption hot melt sleeve pipe connects.Flange connects that to exist compression resistance poor, and inconvenient defective is installed, and utilizes the molten sleeve pipe of electric heating to realize connection between the tube and tube, and then to exist intensity low at the jointing place, the slow and non-removable defective of the high construction of cost.Chinese patent 2888233 discloses a kind of pipeline rapid pipe joint, comprise that two parts insert the interior connection-peg of plastic tube, be with by the fixing O-ring seal of pipe clamp at two interior connection-peg joints, have anti-shedding mechanism at the insertion portion outer side surface of two interior connection-pegs.Solved present employing flange-type connect compression resistance poor, install inconvenient and adopt the molten sleeve of electric heating to connect that join strength is low, cost is high, construction is slow, non-removable shortcoming.Deficiency is that reliability of structure is still waiting further raising.
Summary of the invention
The utility model mainly is to solve the existing in prior technology deficiency, thereby develops a kind of employing plastics
Make, be applicable to the Fast Compression formula joint that connects plastic pipe.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of Fast Compression formula joint, adopt plastic production, it is characterized in that: adapter body with mesopore, pore location at described adapter body two ends is set with seal ring, retainer ring and fastening piece from inside to outside successively, the internal diameter basically identical of described seal ring, retainer ring and fastening piece, respectively there is a nut outside (directly) of described adapter body two ends, and described fastening piece is fastening by nut.The mesopore internal diameter of described adapter body, retainer ring, fastening piece internal diameter are consistent with tube outer diameter.
The technical solution of the utility model can also be further perfect:
As preferably, the stage casing of described adapter body pore location, be provided with the limited step of evagination, limited step is arranged along the footpath, is provided with the placement step of indent vertically to the limited step direction from two ends, and described adapter body two ends are provided with the outside thread with the screw-internal thread fit of nut.
As preferably, described fastening piece be two ends the internal diameter unanimity, on internal diameter, be provided with the frustum of profile of tooth, the big end of cone is provided with boss, fastening piece is provided with an axial pass trough.Described groove plays at nut and screws the certain radial contraction effect of generation in the process.
As preferably, described nut contacts with fastening piece and the conical surface of fastening place for matching with the cone of fastening piece.
As preferably, described retainer ring one end port is provided with step, and the centre is provided with radial groove, and in the placement step of the corresponding cooperation of radial groove radially convex tendon is arranged.
Therefore, the beneficial effects of the utility model are: after connecting the tubing insertion, by tightening nuts extruding fastening piece and retainer ring, thereby contact with pipe fully after holding tubing tightly and allowing seal ring be squeezed and reach seal action, it is simple in structure, and sealing is reliable, and detachably repeatedly uses.
Description of drawings
Accompanying drawing 1 is a kind of structure split schematic representation of the present utility model.
Description of reference numerals: 1, nut, 2, fastening piece, 3, retainer ring, 4, seal ring, 5, adapter body, 6, nut, 7, tubing, 8, tubing inserts mouthful, 9, the conical surface, 10, internal thread, 11, the inclined-plane, 12, profile of tooth, 13, groove, 14, the oral area step, 15, place step, 16, convex tendon, 17, outside thread, 18, limited step.
Embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment: Fast Compression formula joint as shown in Figure 1 is used to connect tubing (comprising: PP-R, PP, pipes such as PVC PE) liquid and carries gas delivery.Working principle: after pipe inserts by nut 1, fastening piece 2, retainer ring 3, seal ring 4, adapter body 5, by tightening nuts 1, extruding fastening piece 2, retainer ring 3, thus hold tubing 7 tightly, and complete the contact with pipe reaches seal action after allowing seal ring 4 be squeezed.
The adapter body 5 of mesopore, the centre of pore location, radially be provided with the limited step 18 of evagination, play the position-limiting action of the tubing at two ends, two ends are provided with the placement step 15 of indent vertically to the limited step direction, and described adapter body two ends are provided with the outside thread 17 that cooperates with the internal thread 10 of nut 1; Placement step 15 places of two ends, be set with seal ring 4, retainer ring 3 and fastening piece 2 from inside to outside successively, the internal diameter of the mesopore internal diameter of described adapter body 5 and retainer ring and fastening piece is identical with the external diameter of tubing 7, respectively there is a nut 6 outside of described adapter body two ends, described fastening piece 2 is fastening by nut 6, and described nut 6 contacts with fastening piece 2 and the conical surface 9 of fastening place for matching with the inclined-plane 11 of the cone of fastening piece 2; Described retainer ring has a circle groove 13 to match with main body inner convex rib 16 outward, and retainer ring 3 and seal ring 4 can not dropped out in adapter body 5.Described fastening piece is the internal diameter unanimity and is provided with the radially frustum of profile of tooth 12, the inclined-plane of cone is 11, the big end of cone is provided with boss, fastening piece 2 is provided with an axial pass trough, cooperate with nut inner conical surface 9 extruding in the nut 1 on fastening piece 2 outer inclined-planes 11 simultaneously by tightening nuts 1, allow profile of tooth 12 sting tight tubing 7 and reach fixing, tight lock effect; Add the effect of seal ring 4, making it to closely cooperate with tubing reaches seal action.
