Description
Technical field
The utility model belongs to the pipe connection and uses accessory, specifically is a kind of gas of plastic material, the connector of liquid delivery pipe.The pipeline that is suitable for the supply of tap water or other gas, liquid or drains occasion uses.
Background technique
The present tap water that generally uses or other gas, liquid Delivery tube, two kinds of the iron pipe of be divided into metal material commonly used and the plastic tubes of non-metallic material.Connector such as elbow, straight-through, threeway, four-way or the like are the indispensable accessories that gas, liquid Delivery tube are installed and used.For iron pipe, make screw thread because tube end is convenient, and screw strength is good, so the structure of connector is often fairly simple, be to be manufactured with corresponding screw thread on the connector and the tube end screw-thread fit tightly gets final product, tube length and pipe paving mode are often unrestricted; For plastic tube, because tube end is inconvenient to make screw thread, the screw strength of making is also bad, so connector does not generally adopt direct thread fiting mode with being connected of tube end, at present common is connected with two kinds: the one, and tube end is made into integration an outer bulge loop, the sheathed gland nut in bulge loop back, screw thread on gland nut and the connector is made screw-thread fit, this pipe length during fabrication just is determined, and can not change, and its use occasion is restricted; The 2nd, establish casing seat on the connector, smooth plastic pipe end is inserted on the casing seat, adopt adhesive to cling, though this Placement is simple, the one-tenth branch of fears are entertained that adhesive causes adverse influence by gas, the liquid of carrying to people or other objects.Chinese patent discloses a kind of lock pressure type pipe joint for No. 90200564.2, has proposed to solve the connectivity scenario of the sub-end of plain tube, but structure is complicated, difficulty of processing is big, cost is higher, and the connection that is used for smooth plastic pipe end is also undesirable; Chinese patent discloses novel pipe connection No. 92227587.4, has also proposed to solve the connectivity scenario of the sub-end of plain tube, but has held smooth tube wall tightly by seal ring, and it is not enough that it connects tightness, do not reach application requirements.
Summary of the invention
For being suitable for, the connector that overcomes existing gas, liquid delivery pipe do not connect smooth plastic pipe end, or it is not enough or adopt that adhesive or structure are complicated, difficulty of processing is big, the more high defective of cost to connect smooth plastic pipe end tightness, the purpose of this utility model provides the connector of a kind of improved plastic gas, liquid delivery pipe, can overcome the defective of prior art.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of gas of plastics, the connector of liquid delivery pipe, comprise connecting body with and on the linkage structure of the smooth plastic pipe of one or more connection end, gas is arranged on the connecting body, the liquid transfer passage leads to the linkage structure place, it is characterized in that having at least a linkage structure is by the screw thread on the connecting body, the spiral pressuring piece, metallic elastic taper collar, packing ring, seal ring constitutes, wherein spiral pressuring piece screw-thread fit is on the screw thread of connecting body, metallic elastic taper collar, packing ring and seal ring are between connecting body and the spiral pressuring piece, the spiral pressuring piece, metallic elastic taper collar, the pore that passes for smooth plastic pipe end is all arranged on packing ring and the seal ring, and the pore peritreme of metallic elastic taper collar is distributed with a breach that extends towards the collar body at least.
Above-mentioned connector can be that an elbow, straight-through, threeway, four-way, pipe plug, pipe cap, other joint or loose joint are first-class.
Above-mentioned called torulopsis plastic pipe end is meant the end that cut off, that do not have the class formation of screw thread, concavo-convex ring in the reprocessing on it at the arbitrary place of plastic pipe.
Above-mentioned metallic elastic taper collar is a special part of the present utility model, is an eyelet, is conical, flexible, and concrete structure can be referring to Fig. 2, Fig. 3.
Metallic elastic taper collar on the above-mentioned linkage structure can be one or more, during a plurality of metallic elastic taper collar, is preferably separated by packing ring between metallic elastic taper collar and the metallic elastic taper collar.
The beneficial effects of the utility model: owing to rotation along with the spiral pressuring piece, after being in the metallic elastic taper collar pressurized between connecting body and the spiral pressuring piece, its tapering becomes big, its pore aperture and diminishes, thereby make metallic elastic taper collar tighten smooth plastic pipe end, with smooth plastic pipe end form drive fit or even the transition fit state, so it is good that it connects tightness, can reach the job requirement of gas, liquid conveying, it is simple in structure, easy processing, cost are low, can avoid the adverse effect of using adhesive to bring.Simultaneously, the utility model also has the simple, fast characteristics of pipeline of laying of installing.
