[Previous technology, the general pipe joints can be divided into plastic materials and copper materials, in which the plastic material is the official joint with the thread for the screw connection, it is easy to produce fine crack damage due to insufficient strength, and the copper material tube Although the joint has better strength, but the weight is heavy and the material cost is high, it is not economical; it is improved by the industry, and the pipe joint structure as shown in the first and second figures is issued. One end of the copper seat (1) is provided with a flange (1), which is provided with an internal thread (12), and the other end extends a turn inner tube (13) to make the outer surface between the inner tube (13) and the flange (11). Forming a accommodating concave surface (10), the plastic injection coating is disposed on the accommodating concave surface (14), and an appropriate size plastic tube (15) is extended to make the inner wall of the plastic tube (15) and the nozzle of the inner tube (13) Between (131), a suitable annular groove (16) is retained, and the 〇利〇-shaped ring (2) is embedded in the annular groove (16), and respectively abuts against the inner wall of the plastic tube (15) and the inner tube of the transition ( 13) The outer wall of the nozzle (131). However, it is checked that the conventional pipe joint structure can combine the advantages of high strength and low material cost, but it still has the following unfavorable shortcomings to be improved: 1. It requires the use of a ring (2), and The 〇-shaped ring 〇 is inserted into the ring groove (10) formed between the nozzles of the inner wall 舆 turnpiece tube (廿) of the hose, so that the assembly operation is inconvenient and the manufacturing cost is high. 2. When the plastic tube (15) is used for the extension tube (3) to be inserted into the assembly, it is easy to leak from the cough plastic tube (15) and the extension tube (3), and the utility is not good. [New content] In view of this, the creator has thoughts and creative ideas, and actively and continuously researches and improves the spirit of perseverance and perseverance, and has conducted multi-disciplinary and trial sample tests, and many revisions and improvements. , is the launch of this creation. The present invention provides an improved pipe joint structure, which is provided with a flange at one end of a curved tubular copper seat, an internal thread is arranged therein, and the other end is extended by a turning inner portion, and the port of the turning inner tube is provided with a meandering expansion connection. The segment is formed to extend the outer surface of the connecting portion and the flange to form a concave surface for the plastic injection coating to be positioned on the receiving concave surface, and to form a curved tubular plastic tube of appropriate size to make the inner wall of the plastic tube and the copper seat A better bond strength between the outer walls prevents leakage between the two. The main purpose of this creation is that it does not need to be equipped with a 〇-shaped ring after injection molding of the plastic tube, so that the manufacturing is simple and the cost is reduced. The second purpose of this creation is that when the plastic tube is used for the insertion of the plastic tube into the extension tube, it can form a tight line with the zigzag shape of the transformation and the inner wall of the plastic tube to achieve a good leakage prevention effect. M294608 [Embodiment] In the following, the preferred embodiment of the present invention will be described in detail with reference to the drawings. As shown in the third cross-sectional view of the third figure, a convex portion of one of the curved tubular copper seats (4) is provided. The edge (41) is provided with an internal thread (42), and the other end extends a turning inner tube (43), and the port of the turning inner tube (43) is provided with a meandering enlarged connecting section (431), and is in a meandering shape. The inner edge of the enlarged connecting section (431) forms a set of slots (4311), and the meandering shape enlarges the outer surface between the engaging section (431) and the flange (41) to form a receiving concave surface (44) for the plastic injection package. Covering the receiving concave surface (44), and extending into the direction of the turning inner tube (43), forming a suitably sized curved tubular plastic tube (45), and expanding the connecting portion (431) by a meandering shape to make the plastic tube (45) and the copper seat (4) Better bonding strength between the outer walls. Assembling the sun shoud, the eye is matched with the cross-sectional view of the embodiment of the present invention, and the internal thread (42) of the curved tubular copper seat (4) is screwed to the external thread (51) of the pipe body (5) to be connected. And an extension tube (6) is glued into the joint of the plastic tube (45), and the sleeve (43) and the plastic tube (43 11) and the plastic tube of the curved tube (4) 45) The inner wall forms a tight bond to achieve a good leak prevention effect. Furthermore, as shown in the cross-sectional view of another embodiment of the fifth drawing, the copper seat (4) may also be a T-shaped shape, and the upper end is provided with a convex portion and a rim (4), and an internal thread (42) is provided therein, and the left and right sides are respectively provided. The end extends a turning inner tube (43,), and the port of the turning inner tube (heart, ) is provided with a zigzag-shaped enlarged index #431 (), and the meandering extension M294608 engaging portion (micro') is formed. a set of joints (the outer surface of the tree ^ connecting section (431) and the flange (41) forms a receiving concave surface (44') for the plastic injection coating to be positioned on the receiving concave surface (44), and to the two In the direction of the inner tube (43), a suitable size of the τ-type plastic tube (milk) is formed, and the connecting portion (43Γ) is expanded by a meandering shape to achieve a better combination between the plastic tube (45,) and the outer wall of the copper seat (4). In the assembly, the internal thread (42) of the copper seat (4) is used to connect the external thread (51) of the pipe body (5), and the two nozzles of the τ type plastic pipe (45') are respectively An extension tube (6) is glued into the assembly, and the extension tube (6) is tightly bonded to the inner sleeve of the copper sleeve (4) and the inner wall of the plastic tube (45,). To achieve good leakage prevention effect. From the structure of the above specific embodiment, it can be known that the creation has the following benefits: 1. It does not need to be installed after the plastic tube (45), (45,) is injection molded. The 〇-shaped ring is easy to manufacture, the components are reduced, and the manufacturing cost is reduced. 2. The plastic tube (45), (45,) can be bent with the copper seat (4) when the extension tube (6) is glued into the assembly. The enlarged expansion joints (431), (431,) and the inner walls of the plastic tubes (45) and (45') form a tight bond to achieve a good winter leakage prevention effect, and thus have better practicability. This creation has indeed reached a breakthrough structure, and has improved content of creation, while at the same time being able to achieve industrial use and progress I1 and this creation has not been seen in any publication, but also novel, when it meets the special M294608 Lifa's provisions, 新型 提 提 提 提 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查 审查Limit the scope of the implementation of this creation; Where modifications and alterations under this patent-pending creation of the range made, all should still be within the scope of this patent covers the creation.
