Abstract
The utility model relates to a one injection molding electric heating fritting type plastic pipe joint with a metal frame. The electric heating fritting type plastic pipe joint is characterized in that the metal frame (2) increasing strength and rigidity is arranged in a plastic pipe joint body (1). The metal frame (2) is provided with uniformly distributed small holes to cause the metal frame and the body to be well combined. The inner surface of the pipe joint body is laid with a resistance wire (3). Both ends of the resistance wire are provided with wiring terminals (4) fixed on both ends of the pipe joint to be leaded out in an axial or a radical direction mode.
Description
The utility model relates to a kind of electric heating smelting formula pipe joint that is used to connect plastic conduit.
One of connected mode commonly used of known present thermoplastic pipeline is to adopt electric heating smelting formula joint, this joint is to use the thermoplastic identical with the tubing plastics to make sleeve pipe or pipe fitting (elbow, threeway, four-way etc.), on sleeve pipe or pipe fitting inner wall surface around laying resistance wire.Straight tube is inserted sleeve pipe or pipe fitting, resistance wire is connected power supply, resistance wire heats up sew that heating makes sleeve pipe or pipe fitting inner wall and straight tube outer wall junction together, and pipeline has melted together with regard to close and firm ground behind the cooling curing of cutting off the electricity supply.This kind joint quality of connection height, easy to use, speed of application have obtained to use widely soon.But, makes by above-mentioned joint because being single plastic material, intensity and rigidity are all limited, be used to connect pure plastic pipe and still can satisfy the equal strength requirement, but bonding strength does not just reach the intensity that equates with tubing when being used to connect highstrenghtpiston's pipeline the metallic framework plastic composition pipeline of announcing such as China patent ZL942096126.
The purpose of this utility model is to provide a kind of electric heating smelting formula joint for plastic tube that has the metallic framework inserts, realizes being connected with the equal strength of metallic framework plastic composition pipeline.
Electric heating smelting formula joint for plastic tube of the present utility model comprises on the pipe joint body internal surface around what lay and partly buries half-naked resistance wire and be fixed on pipe joint body two ends with binding post axial or that radial manner is drawn, binding post is connected with the resistance wire two ends, the pipe joint body is embedded with and the corresponding metallic framework inserts of body shape, have on the inserts and guarantee that itself and body are in the locating pin of correct relative position mutually, also be provided with the equally distributed eyelet of assurance itself and body good combination on the inserts.
Pipe joint of the present utility model is because the booster action strength rigid of metallic framework all is better than existing pure plastics electric heating smelting formula joint for plastic tube.Be applicable to and connect highstrenghtpiston's pipeline.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the structural representation of straight connector of the present utility model;
Fig. 2 is a using method schematic diagram of the present utility model;
Fig. 3 is 90 ° of elbow joints schematic diagrames of the present utility model;
Fig. 4 is a three-way connection schematic diagram of the present utility model.
Comprise pipe joint body (1) referring to Fig. 1 electric heating smelting formula of the present utility model joint for plastic tube, metallic framework inlay (2), resistance wire (3), binding post (4).Wherein body (1) is a thermoplastic, metallic framework inlay (2) embeds in the body (1) and plays a part to gain in strength and rigidity, inlay (2) can be opened the welding of equally distributed hole and reel by sheet metal and make, also can form by the smart casting of metal, also can be made by wire welding node after weaving into shape, equally distributed eyelet plays the effect that makes inlay and body plastics good combination on it.The metallic framework inlay is in correct relative in the pipe joint body when making the pipe joint single injection-molded, and equally distributed radial location nail (5) is set on inlay.Resistance wire (3) partly buries half-naked state around being on the inner body wall that is laid in.Binding post (4) links to each other with resistance wire and is fixed on the body two ends and draws with axial or radial manner.Above-mentioned each parts make up by single injection-molded.
Referring to Fig. 2, in use, only need straight tube is inserted relatively to leaning on, the binding post both positive and negative polarity is connected power supply and certain time, resistance wire (3) heat fused, welding, hot melting plastic treats that plastics fuse mutually, behind the deenergization cooling curing pipeline with regard to close and firm link together.
Fig. 3 and Fig. 4 represent that the utility model pipe joint makes the form of elbow and threeway, and the electric heating smelting formula joint for plastic tube that has metallic framework of the present utility model can be threeway and the four-way connection between elbow joints between 0-180 ° and 0-90 °.In fact, pipe joint of the present utility model as the case may be also can have various ways, and any electric heating smelting formula joint for plastic tube that has the metallic framework inserts all belongs to notion of the present utility model and category.
Claims (7)
1. electric heating smelting formula joint for plastic tube, comprise on the pipe joint body internal surface and partly bury half-naked resistance wire and be fixed on pipe joint body two ends with binding post axial or that radial manner is drawn around what lay, binding post is connected with the resistance wire two ends, it is characterized in that, the pipe joint body is embedded with and the corresponding metallic framework inserts of body shape, has on the inserts to guarantee that itself and body are in the equally distributed eyelet that the locating pin of correct relative position and inserts are provided with assurance itself and body good combination mutually.
2. pipe joint according to claim 1 is characterized in that, the metallic framework inserts opens equally distributed hole by sheet metal and the reel welding is made.
3. pipe joint according to claim 1 is characterized in that, the metallic framework inserts is made by the smart casting of metal.
4. pipe joint according to claim 1 is characterized in that, metallic framework is made around weaving into the welding of shape posterior nodal point by wire.
5. pipe joint according to claim 1 is characterized in that, pipe joint is 0-180 ° a elbow.
6. pipe joint according to claim 1 is characterized in that, pipe joint is 0-90 ° a three-way connection.
7. pipe joint according to claim 1 is characterized in that, pipe joint is 0-90 ° a four-way connection.
