Abstract
The utility model relates to a bending pipe joint used in the water warming, including a locking screw cap with the inner screw thread, a pressing copper ring arranged on the circular surface outside the pipe and a joint body; the pressing ring is provided with the inner and outer screw thread; the joint body is composed of a pipe body and a connecting element; the pipe body is fixed and connected with the connecting element to be an integrated body. The utility model is characterized in the reasonable structure, low manufacturing cost, no leakage, security, stability and so on. In particular, the aluminum-plastic material is used as the main material of the pipe joint and the joint end is made of copper, which greatly reduces the manufacturing cost and saves the resources.
Description
Technical field
The utility model relates to a kind of pipe joint, especially a kind of bending pipe joint that is used for the hot-water heating aspect.
Background technique
Water heating fittings is used quite extensive, and the pipe joint that connects water pipe is one of them.Pipe joint of the prior art generally adopts copper product to make, structure comprises body, compresses copper ring, locking screw emits, body is provided with outside thread, compressing copper ring is sleeved on the pipe fitting, emitting by locking screw makes pipe fitting connect with body again, this kind structural type is commonplace, using effect is good, the situation of generation leakage seldom, but the manufacture cost height, international especially in recent years copper material price is very high, considers from the angle of economical with materials cost, also the someone has designed a kind of aluminium-plastics composite pipe joint of replacing whole copper, and structure is consistent with copper sleeve.But in actual use, occur leakage, situation such as fragile, insecure easily, brought very big inconvenience to productive life.The pipe joint that designs a kind of new structure of rational in infrastructure, safety and stability has very big economic benefit and social benefit.
Summary of the invention
Originally the purpose that is model utility is a kind of simple in structure, easily manufactured, combined type pipe joint that cost is low of design, and the technical solution of the utility model is so to realize:
A kind of combined type pipe joint, what comprise that tapped locking screw emits, is located at the pipe periphery compresses copper ring and joint body, hold-down ring is provided with internal and external screw thread, joint body (4) is to be made up of body (14) and link (3), described body (14) is fixedly connected with link (3), is integral the formula structure; Link (3) one ends are provided with and manage the profile of tooth interface (7) that is connected, and the other end connects with the interface end (12) of body (14).
As preferably, the interface end of body (14) is provided with ring groove (9), described link (3) is provided with annular boss (8) with body (14) interface end (12) joining end, and described annular boss (8) connects with body (14) with the corresponding setting of ring groove (9), fastening connection piece (3).
As preferably, locking screw emits (1) to be double layer construction, in establish tapped metal layer (21), skin is the plastic-aluminum layer.
As preferably, annular boss (8) outer ring surface of link (3) bottom is provided with concaveconvex structure (11), and described concaveconvex structure (11) is corresponding with body (14) interface end.
As preferably, body (14) is made by aluminium plastic material, and link (3) is a copper spare.
As preferably, lock metal layer (21) periphery and be provided with the annular groove that connects interlock with the plastic-aluminum layer.
As preferably, annular boss (8) opening end also is provided with location snap ring (17) and one group of recess (15), the interlock of convenient and ring groove (9).
Model utility has designed a kind of simple in structure, pipe joint that cost is low.Different with plastic-aluminum combined joint of the prior art is, has mainly improved the interface end of pipe joint and the cooperating structure of different materials, has following characteristics:
1, rational in infrastructure, the technical program is divided into the pipe joint body body (14) and link (3) two-part cleverly, adopts annular boss (8) and ring groove (9) fastening between two-part, and both are into a single integrated structure to make it, and are during use, reliable and stable.
2, low cost of manufacture, it is the pipe joint main material that the technical solution of the utility model adopts aluminium plastic material, interface end adopts copper spare, greatly reduces manufacture cost, has saved resource.
3, the pipe joint interface end adopts that copper spare guaranteed to use does not leak, safety, has the using effect the same with the copper pipe joint.
