Abstract
The utility model relates to the technical field of plastic products and provides an anti-seepage insert structure which comprises plastic and a copper insert. The copper insert is embedded in the plastic, an annularly-protruding first anti-seepage portion is arranged on the outer surface of one end of the copper insert, a plurality of convex blocks are arranged on the outer surface of the other end of the copper insert, and annularly-protruding second anti-seepage portions are arranged between the first anti-seepage portion and the convex blocks. The first anti-seepage portion, the convex blocks and the second anti-seepage portions are arranged on the outer surface of the copper insert, so that contact area between the copper insert and the plastic is increased, and anti-seepage effect of two end portions and the middle portion is improved. The anti-seepage insert structure is simple and reasonable in structure and easy to process and manufacture, and the problem of water seepage can be effectively solved.
Description
Technical field
The utility model relates to plastic product technical field, more specifically, relates to a kind of insert structure of leakage proof.
Background technique
In prior art, plastic insert is exactly to be embedded in metal parts, glass or in type plastic etc. to form the firm entirety that can not unload at plastics, its objective is local strength in order to increase plastics, hardness, wear resistance, magnetic conduction electric conductivity etc.PPR inserts is a kind of conventional plastic insert, due to structure, the Shooting Technique of inserts, and the reasons such as mould, in use often there is water leakage phenomenon in PPR inserts, and the size of PPR inserts is less, this water leakage phenomenon is just obvious all the more.For solving the seepy question of PPR inserts, part PPR inserts increases the wall thickness of plastic outer layer, does like this and can effectively solve seepy question, but increased cost of production.
Model utility content
The utility model is intended to solve the problems of the technologies described above at least to a certain extent.
The purpose of this utility model is to provide a kind of simple and reasonable, is easy to manufacturing, effectively solves the insert structure of the leakage proof of seepy question.
The utility model solves the technological scheme that its technical problem adopts: a kind of insert structure of leakage proof, comprise plastics and copper insert, described copper insert is embedded in plastics, one end outer surface of described copper insert is provided with the first leakage barriers that annular is protruded, the other end outer surface of described copper insert is provided with some projections, is provided with the second leakage barriers that annular is protruded between described the first leakage barriers and projection.
The utility model is provided with the first leakage barriers, projection and the second leakage barriers at the outer surface of copper insert, increase the area of contact between copper insert and plastics, improve the leak preventing effect at two end part and middle part, simple and reasonable, be easy to manufacturing, can effectively solve seepy question.
In a preferred implementation, described the first leakage barriers is provided with the first fillet near one end of copper insert end, the other end of described the first leakage barriers is provided with the second fillet, can increase the package power between end and the plastics of copper insert, thereby further effectively prevents the generation of water leakage phenomenon.More preferably, described the first fillet is greater than the second fillet, and guaranteeing has enough package powers between the end of copper insert and plastics.
In a preferred implementation, the two ends of described the second leakage barriers are respectively equipped with the 3rd fillet, can increase the package power between middle part and the plastics of copper insert, thereby further effectively prevent the generation of water leakage phenomenon.More preferably, 1/4 ~ 1/3 of the width that described the 3rd fillet is the second leakage barriers, is easy to manufacturing.
In one embodiment, described projection is uniformly distributed along the outer surface of copper insert, guarantees overall leakproof, is convenient to manufacturing simultaneously, and beautiful shape is generous.Preferably, the quantity of described projection is 6 ~ 10.
The beneficial effects of the utility model are: the utility model is provided with the first leakage barriers, projection and the second leakage barriers at the outer surface of copper insert, increase the area of contact between copper insert and plastics, improve the leak preventing effect at two end part and middle part, simple and reasonable, be easy to manufacturing, can effectively solve seepy question.
Brief description of the drawings
Fig. 1 is an embodiment's of the utility model cross-sectional view.
Fig. 2 is the enlarged view of A part in Fig. 1.
Fig. 3 is the structural representation of copper insert in embodiment of the utility model.
Accompanying drawing, only for exemplary illustration, can not be interpreted as restriction of the present utility model; For better explanation embodiment, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing some known features and explanation thereof may to omit be understandable.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1 to Figure 3, the insert structure of a kind of leakage proof of the present utility model, comprise plastics 1 and copper insert 2, described copper insert 2 is embedded in plastics 1, one end outer surface of described copper insert 2 is provided with the first leakage barriers 21 that annular is protruded, the other end outer surface of described copper insert 2 is provided with some projections 22, is provided with the second leakage barriers 23 that annular is protruded between described the first leakage barriers 21 and projection 22.
The utility model is provided with the first leakage barriers 21, projection 22 and the second leakage barriers 23 at the outer surface of copper insert 2, increase the area of contact between copper insert 2 and plastics 1, improve the leak preventing effect at two end part and middle part, simple and reasonable, be easy to manufacturing, can effectively solve seepy question.
Described the first leakage barriers 21 is provided with the first fillet R1 near one end of copper insert end, the other end of described the first leakage barriers 21 is provided with the second fillet R2, can increase the package power between end and the plastics 1 of copper insert 2, thereby further effectively prevent the generation of water leakage phenomenon.In the present embodiment, described the first fillet R1 is greater than the second fillet R2, and guaranteeing has enough package powers between the end of copper insert 2 and plastics 1.
The two ends of described the second leakage barriers 23 are respectively equipped with the 3rd fillet R3, can increase the package power between middle part and the plastics 1 of copper insert 2, thereby further effectively prevent the generation of water leakage phenomenon.In the present embodiment, 1/4 ~ 1/3 of the width that described the 3rd fillet R3 is the second leakage barriers 23, is easy to manufacturing.
