Background technique
In the installation of existing plastic tube or aluminium-plastic composite pipe, all adopted the hot melt ways of connecting, it is the joint by heating pipe fitting 1 and tubing 2, and applies certain pressure, it is welded together, referring to shown in Figure 1.Traditional hot melt connection pipe fitting, though it is reliable to connect sealing, because its structure imperfection, the intersection at pipe fitting and tubing when hot melt connects has 21 generations of hot melt overflow, has had a strong impact on the attractive in appearance of pipeline and finishing effect.In the pipe-line system that the pipe technology of hot melt connection in the past only is applied to secretly bury, can't be applied to the finishing pipe-line system of peripheral hardware.Especially aluminium-plastic composite pipe is applied to the finished system of peripheral hardware more, as not covered up the hot melt overflow, then is difficult to the hot melt interconnection technique is applied in the aluminium-plastic composite pipe.
Summary of the invention
The technical problems to be solved in the utility model is not have after pipe fitting is connected with the tubing hot melt to expose the hot melt overflow.
Technical solution of the present utility model is such: a kind of hot melt connection pipe fitting, comprise joint body, tubing, and the outside, described joint body one end is provided with end cap.Described end cap one side is provided with joint, and opposite side is a cap.The joint of described end cap is provided with and connects tongue or connect screens or connection internal thread or attachment hole; In connecting tongue, also be provided with the dismounting groove.The end of described joint body is provided with the joint and the spacing shaft shoulder.End cap is integral body or split; The end cap of split is provided with upper end cap and lower end cap.The joint of described joint body is provided with and connects groove or connect boss or connection outside thread or coupling shaft.The cap internal diameter of described end cap is slightly larger than the external diameter of being taken over material.
Compared with prior art, the utlity model has following beneficial effect: it not only has all functions of general hot melt pipe fitting, and, improved the beauty defects in the general hot melt pipeline effectively.The overflow that hot melt is produced when connecting, the end cap elegant in appearance by configuration design wraps up, covers, whole in appearance joint transitions smooth, smooth and easy.The utility model is suitable for the application of the bright dress of exterior wall pipe network of plastic tube, the connection of aluminium-plastic composite pipe hot melt.Simultaneously, be provided with the dismounting position on the end cap specially, make things convenient for the end cap dismounting.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further elaborated.
Shown in Fig. 2-5,1 one kinds of hot melt connection pipe fittings of the utility model embodiment are made up of joint body 1, tubing 2, and the outside, end of described joint body 1 is provided with end cap 3.End cap 3 one sides are provided with joint 31, and its opposite side is a cap 32.Described joint 31 adopts the tongue linkage structure, and corresponding joint body 1 joint adopts the groove linkage structure.The joint 31 of end cap 3 is provided with and connects tongue 311; Be provided with dismounting groove 315 in this connection tongue 311.Earlier end cap 3 is inserted in the tubing 2 that will connect before connecting, the end cap opening is to tubing 2 connecting ends.Respectively the joint of joint body 1 and tubing 2 is heated to predetermined temperature with special tool, apply external force and make joint body 1 and tubing 2 weldings, produce connecting the hot melt overflow 21 that intersection can influential outward appearance this moment, applies external force and force connection tongue 311 on the end cap joint 31 to snap in the connection groove 111 of joint body joint 11 till end cap 3 is withstood by the spacing shaft shoulder 12 on the joint body 1.End cap 3 promptly firmly was stuck on the joint body 1, was played the effect of covering up hot melt overflow 21 this moment, had improved by the outward appearance of jointed tubular workpieces, had improved the finishing effect of pipeline.When pipeline maintenance or other occasion need be pulled down end cap, the dismounting groove 315 on the light sled of available instrument one lower end cap can be pulled down end cap.
Shown in Fig. 6-10, the end cap joint of present embodiment adopts the bayonet socket linkage structure, and corresponding joint body joint adopts the boss linkage structure.The joint 31 of end cap is provided with and connects screens 312; End cap is provided with upper end cap 33 and lower end cap 34 for dividing body structure.After taking over material 2 and joint body 1 welding, apply external force, force the bayonet socket 312 of end cap 3 to snap in the connection boss 112 of joint body 1 end respectively, should guarantee in the process of press in that upper and lower end cap 33,34 arrives at the spacing shaft shoulder 12 on the joint body 1 simultaneously.End cap promptly firmly was stuck on the joint body, was played the effect of covering up hot melt overflow 21 this moment, had improved the outward appearance of pipe fitting, had improved the finishing effect of pipeline.
