Description
Technical field
The utility model relates to a kind of water pipe structure, specifically a kind of structure that plastic water pipe metal is spirally connected.
Background technique
Currently, occurring a kind of the end of plastic water pipe being cast in the knot that threaded metalwork both makes to be integrally formed
Structure, pipe fitting adjacent so are mutually spirally connected by the internal screw thread and external screw thread of metalwork and are connected, and bonding strength is improved.
As shown in Figure 1, at present under structure, metalwork is to expose plastic part end, and the metal being located in plastic part
The length of part part is also inadequate, although metalwork and plastic part are cast on together, but water still can pass through metalwork
It is leaked out with the interface of plastic part, such as A the and B route of Fig. 1, leakproofness is poor.
Utility model content
The utility model provides a kind of water pipe spiro connection structure, the purpose is to solve the disadvantage that the prior art, improves plastic part
The leakproofness of the water pipe spiro connection structure combined with metalwork casting.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of water pipe spiro connection structure, it is special with plastic tube and the threaded metal tube being integrated with plastic tube casting
Sign is: metal tube has inner ring and outer rings, and metal tube annular groove is formed between inner ring and outer rings, and plastic tube is equipped with plastics pipe ring
The inner ring of slot, metal tube is inserted into plastic tube annular groove, and plastic tube is located at the insertion metal of the plastic tube tube body on the outside of plastic tube annular groove
In pipe ring slot, the end face that plastic tube is located at the plastic tube tube body on the outside of plastic tube annular groove is wrapped up by metal tube annular groove.
When metal tube is external screw thread metal tube, the opposite direction of interior circumferential direction metal tube and ring slot extends external screw thread tube body, outer spiral shell
The outer wall of line tube body is equipped with external screw thread, and plastic tube is located at end face and the male-pipe of the plastic tube tube body on the inside of plastic tube annular groove
The end face of body is aligned.
When metal tube is thread metal, the inner wall of inner ring is equipped with internal screw thread, and plastic tube is located in plastic tube annular groove
The end face of the plastic tube tube body of side is lower than the end face of inner ring, and exposes internal screw thread.
Metal tube tube wall is equipped with several annular protrusions.
The utility model has the beneficial effect that
The end of the inner wall of the plastic tube of the utility model is located within the end of the inner wall of metal tube, or, plastic tube
The end part aligning of the inner wall of the end and metal tube of inner wall, and the outboard end of plastic tube is wrapped up by metal tube, is considerably increased
The area that metal tube is contacted with plastic tube, water needs longer distance that could ooze out, to strengthen leakproofness.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is prior art cross-sectional view；
Fig. 2 is the utility model section view.
Specific embodiment
In order to illustrate more clearly of the technical solution of the utility model, attached drawing needed in description will be made below
Simply introduce, it should be apparent that, the drawings in the following description are merely some embodiments of the present invention, for this field
For those of ordinary skill, without creative efforts, it can also be obtained according to these attached drawings other implementations
Example.
It is as shown in Figure 2:
The external screw thread metal tube that the utility model has external screw thread plastic tube 1 and is integrated with the casting of external screw thread plastic tube 1
It 2 and internal screw thread plastic tube 3 and casts the thread metal 4 that is integrated with internal screw thread plastic tube 3.
External screw thread metal tube 1 has inner ring 11 and outer ring 12, is formed between the inner ring 11 and outer ring 12 of external screw thread metal tube 1
The opposite direction of one external screw thread metal tube annular groove 13, the outside screw thread metal pipe annular groove 13 of inner ring 11 extends external screw thread tube body 14,
The outer wall of external screw thread tube body 14 is equipped with external screw thread 15, and the inner ring 11 of external screw thread metal tube 1 is inserted into set by external screw thread plastic tube 2
In external screw thread plastic tube annular groove 21, the plastic tube tube body 22 that external screw thread plastic tube 2 is located at 21 outside of external screw thread plastic tube annular groove is inserted
Enter in external screw thread metal tube annular groove 13, the end face of such plastic tube tube body 22 is just wrapped up by external screw thread metal tube annular groove 13, outside
Threaded plastic pipe 2 is located at the end face of the plastic tube tube body 23 of 21 inside of external screw thread plastic tube annular groove and the end face of external screw thread tube body 14
Alignment.The tube wall of external screw thread metal tube 1 is equipped with several annular protrusions 10.
Thread metal 3 has inner ring 31 and outer ring 32, is formed between the inner ring 31 and outer ring 32 of thread metal 3
One thread metal annular groove 33, the inner wall of inner ring 31 are equipped with internal screw thread 35, and the inner ring 31 of thread metal 3 is inserted into interior
In internal screw thread plastic tube annular groove 41 set by threaded plastic pipe 4, internal screw thread plastic tube 4 is located at 41 outside of internal screw thread plastic tube annular groove
Plastic tube tube body 42 be inserted into thread metal annular groove 33 in, internal screw thread plastic tube 4 is located in internal screw thread plastic tube annular groove 41
The end face of the plastic tube tube body 43 of side is lower than the end face of inner ring 31 and exposes internal screw thread 35.On the tube wall of thread metal 3
Equipped with several annular protrusions 30.
In actual use, external screw thread 15 and internal screw thread 35 are screwed, in this way, water, which will ooze out, will pass through C route and the road D
Line, and C route will pass through annular protrusion 10, and D route will pass through annular protrusion 30, so significantly than the prior art route A, B
Increase, leakproofness greatly enhances.
