Abstract
The utility model discloses a fore shaft compressive jointing pipe component comprising a structure of a connecting joint and a connecting metal pipe, the connecting joint is provided with an ejecting fore shaft, screw teeth are arranged at the external circle end of the ejector, the connection of the metal pipe and the connecting joint is a hackle external rib curved surface where the top end of the ejector reaches the metal pipe, the seal is implemented by the screw teeth of the ejecting fore shaft fastening ejector connected with the connecting joint, the utility model has the obvious advantages that the connection is easy, the seal is reliable, the operation is convenient, and the working efficiency is prominently raised and defects of unreliable adherence and reduced inner diameter with inner sunken are avoided without affections from overheating, manufacturing material of a single pipe joint can be saved up to more than 50 percent, the disadvantages of mass consumption of manufacturing material and high accumulated cost are comparatively overcome which facilitates popularization application.
Description
One, technical field:
A kind of locking notch compression type connecting pipe fitting of the utility model relates to plumbing pipe and pipeline connecting pipe fitting technical field thereof, is applied to thin metallic tubd.
Two, background technique:
At present, the hot-water heating pipe of being supplied on the market adopts the pipeline of traditional galvanized pipe substantially, connect with pipe joint with internal thread, very easy oxide etch, influenced actual working life, polluted water, aluminium-plastic composite pipe can overcome and reduce water pollution, because in water, and, cause plastic-aluminum combined tracheal rupture easily with the aluminium skin corrosion of centre and lose intensity, leak, again because aluminium-plastic composite pipe is caught a cold by heat expansion to contract easily, time one is of a specified duration, has influenced the sealing of bayonet connection, and the water leakage phenomenon that is caused happens occasionally, what then come is to substitute above-mentioned three kinds of pipeline materials with stainless steel-plastic composite pipe, but 1-adopts bonding method that pipeline and pipe joint are bonded together, and relates to adhesion technique requirement height, relatively lack technical support, be difficult to use in field boundary and close with uniform temperature; 2-adopts at the pipeline material jointing and adds being connected and sealed of pipeline connecting pipe fitting with the method for indent, the problem that takes place is to be cost to sacrifice internal diameter of the pipeline, and connection relative complex, the pipe fitting that 3-has a kind of pipeline material jointing to be connected and sealed by pipeline connecting pipe fitting with the pipe fitting of evagination again, kept internal diameter, Placement is advanced relatively, but owing to the material that connection pipe fitting is used is more, the cost of single-piece pipe fitting is higher, cumulative cost is high, has directly influenced the promotion and application of this connection pipe fitting.
Three, summary of the invention:
The purpose of this utility model is the structure of inverter tube pipe connecting, shortens connecting tube connecting tube length, reduces the materials consumption of connection pipe fitting, thereby reduces cost per unit, reaches a kind of locking notch compression type connecting pipe fitting of long-time firm connection.Its technology is achieved in that and comprises jointing, metal tube is in interior structure, it is characterized in that: jointing is provided with the head part fore shaft, the outer nose circle of head part is provided with thread, it is the outer convex rib curved surface that metal tube is arrived on the head part top that metal tube is connected with jointing, thread by the head part fore shaft padlock head part of jointing disjunctor seals, the outer convex rib curved surface of metal tube can be triangle, circular arc, zigzag fashion, trapezoidal structure, the jointing that one or both ends are provided with the head part fore shaft comprises single connecting head, straight-through jointing, 45-90 ° of elbow, the threeway jointing, ride and bend interior, the spanner that the head part outer end is provided with can be a hexagon, octagon or circular circumference are provided with the hook spanner hole.Its tangible advantage is, easy to connect, it is firm to seal, and operation is convenient, has improved work efficiency, stopped the defective that bonding not firm and indent reduces internal diameter, be not subjected to the evident characteristic of overheated influence, the material economy of single-piece pipe fitting has overcome relatively owing to the used material of connection pipe fitting is more more than 50%, the defective that cumulative cost is high is beneficial to apply.
Four, description of drawings:
Fig. 1 is the structural representation of example for connecting thin-wall stainless steel with straight-through jointing;
Wherein, 1-outer convex rib curved surface, 2-head part fore shaft, 3-head part, 3-1-spanner position, 4-thin-wall stainless steel, 5-jointing;
Five, embodiment:
Below in conjunction with accompanying drawing, the utility model is further described:
See accompanying drawing 1, jointing (5) two ends are provided with head part fore shaft (2), the outer nose circle of head part (3) is provided with thread, the outer end is provided with spanner position (3-1), the thread of head part fore shaft (2) the padlock head part (3) of the zigzag outer convex rib curved surface (1) of thin-wall stainless steel (4) and jointing (5) disjunctor.
See accompanying drawing 1; outer head part (3) the back roll extrusion outer convex rib curved surface (1) that is inserted in of thin-wall stainless steel (5); the thin-wall stainless steel (5) that rolls out outer convex rib curved surface (1) enters jointing (5); be hexagonal spanner position (3-1) with what spanner was moved head part (3); the thread that the outer nose circle of head part (3) is provided with screws in the head part fore shaft (2) of disjunctor on the jointing (5); make head part (3) arrive at the outer convex rib curved surface (1) of thin-wall stainless steel (5), until sealing; The connecting means of the other end is identical, no longer is described in detail,
This connection is applicable to that one or both ends are provided with the jointing of head part fore shaft (2) (5) and comprise single connecting head, straight-through jointing, 45-90 ° elbow, threeway jointing, the various combination of riding and bending, implement the connection of the various combinations of the different trends of pipeline, the cross section of the outer convex rib curved surface (1) of its thin-wall stainless steel (5) can be triangle, circular arc, zigzag fashion, trapezoidal structure.
Claims (4)
1. locking notch compression type connecting pipe fitting, the structure that comprises jointing (5), metal tube (4), it is characterized in that: jointing (5) is provided with head part fore shaft (2), the outer nose circle of head part (3) is provided with thread, it is the outer convex rib curved surface (1) that metal tube (4) is arrived on head part (3) top that metal tube (4) is connected with jointing (5), is sealed by the thread of head part fore shaft (2) the padlock head part (3) of jointing (5) disjunctor.
