Abstract
The invention relates to a reinforced connecting structure of a metal insert and a plastic piece. The structure consists of the plastic piece and the metal insert, wherein the inner section of the metal insert is in a cylindrical pipe shape and is embedded into the plastic piece; the circumferential surface of the inner section of the metal insert is provided with at least one bulge or pit or through hole or thorn along the circumferential direction; and any one bulge or pit or through hole or thorn is encircled or filled by the plastic piece. When the plastic piece is subjected to injection molding, plastic can pass through the through hole or is filled in the pit, so that the combining surface of the metal insert and the plastic piece is increased; and the plastic piece is positioned in the stress direction of the metal insert, so that the metal insert is effectively prevented from being separated from the plastic piece.
Description
Technical field:
The present invention relates to pipe transportation technology, relate in particular to pipe joint, the enhancing linkage structure of particularly a kind of metal insert and plastic parts.
Background technique:
In the prior art, metal insert combines the pipe joint that constitutes and is widely used in the piping erection engineering with plastic parts.In installation and using process, can produce circumferential and axial active force between metal insert and the plastic parts, cause metal insert and plastic parts to be thrown off, influence sealing effect and safety in utilization.
Summary of the invention:
The object of the present invention is to provide the enhancing linkage structure of a kind of metal insert and plastic parts, the enhancing linkage structure of described this metal insert and plastic parts will solve metal insert and plastic parts disengagement in the pipe joint in the prior art, influence the technical problem of sealing effect.
The enhancing linkage structure of this metal insert of the present invention and plastic parts is made of a plastic parts and a metal insert, the inner segment of described metal insert is cylindrical tube and is embedded in the described plastic parts, wherein, along the circumferential direction be provided with projection or pit or the through hole or the quil of at least one number in the inner segment circumferential surface of described metal insert, any one described projection or pit or through hole or quil surround or fill by described plastic parts.
Further, the inner segment circumferential surface of described metal insert is provided with the projection of at least one number, and the dorsal part of any one described projection all is the pit shape.
Perhaps, the inner segment circumferential surface of described metal insert is provided with the through hole of at least one number, and a side at the edge of any one described through hole all is connected with a quil, and described quil protrudes from the inner segment circumferential surface of metal insert.
Further, described quil covers on the described through hole.
Working principle of the present invention is: the projection or pit or through hole or the quil that along the circumferential direction are provided with at least one number in the inner segment circumferential surface of metal insert, when plastic parts injection moulding, plastic cement can pass through hole, perhaps be filled in the pit, thereby increased the junction plane of metal insert and plastic parts, and plastic parts is positioned at being subjected on the force direction of metal insert, prevents the disengagement of metal insert and plastic parts.
The present invention and prior art are compared, and its effect is actively with tangible.The present invention along the circumferential direction is provided with projection or pit or the through hole or the quil of at least one number in the inner segment circumferential surface of metal insert, when plastic parts injection moulding, plastic cement can pass through hole, perhaps be filled in the pit, thereby increased the junction plane of metal insert and plastic parts, and plastic parts is positioned at being subjected on the force direction of metal insert, has effectively prevented the disengagement of metal insert and plastic parts.

Embodiment:
Embodiment 1:
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and shown in Figure 7, the enhancing linkage structure of metal insert of the present invention and plastic parts, constitute by a plastic parts 2 and a metal insert 1, the inner segment of described metal insert 1 is cylindrical tube and is embedded in the described plastic parts 2, wherein, along the circumferential direction be provided with the projection of at least one number in the inner segment circumferential surface of described metal insert 1, perhaps pit 5, perhaps through hole 3, perhaps quil 4, any one described projection, perhaps pit 5, perhaps through hole 3, perhaps quil 4 surrounds or fills by described plastic parts 2.
Further, the inner segment circumferential surface of described metal insert 1 is provided with the projection of at least one number, and the dorsal part of any one described projection all is the pit shape.
Perhaps, the inner segment circumferential surface of described metal insert 1 is provided with the through hole 3 of at least one number, and a side at the edge of any one described through hole 3 all is connected with a quil 4, and described quil 4 protrudes from the inner segment circumferential surface of metal insert 1.
Further, described quil 4 covers on the described through hole 3.
The working principle of the foregoing description is: the projection or pit 5 or through hole 3 or the quil 4 that along the circumferential direction are provided with at least one number in the inner segment circumferential surface of metal insert 1, when plastic parts 2 injection mouldings, plastic cement can pass through hole 3, perhaps be filled in the pit 5, thereby increased the junction plane of metal insert 1 with plastic parts 2, and plastic parts 2 is positioned at being subjected on the force direction of metal insert 1, prevents metal insert 1 and plastic parts 2 disengagements.
