Description

Metal embedded part

Technical Field

The utility model relates to an embedded part technical field, concretely relates to metal embedded part.

Background

In various plastic pumps, plastic valves, and other plastic articles, these plastic articles are connected to other components. Because the plastic strength is not enough, threaded holes or other hole grooves for connection and the like cannot be directly formed in the plastic products, and in order to overcome the connection problem, the metal parts embedded in the plastic products are the better options for fastening and connecting the plastic pumps, the plastic valves and various plastic products at present. In a common method, a metal part is embedded in a plastic product during molding, a threaded hole is formed in the metal part, and the like, so that the connection strength of the plastic product is greatly improved compared with that of a pure plastic product.

The existing metal embedded part comes out from a machine tool, the metal embedded part is generally annular, the cross section of the metal embedded part is rectangular, so that the metal embedded part has sharp edges and corners, and the threaded hole is directly formed in a rectangular body. Because the connection needs great stress to ensure the tight connection relation, due to vibration or other reasons, a stress can be generated between the metal embedded part and the plastic product, and the stress can cause the generation of a gap between the metal embedded part and the plastic product, particularly the existence of an edge angle, thereby greatly accelerating the formation of the gap between the metal embedded part and the plastic product. After long-time use, the plastic product cracks to cause the metal embedded parts to be exposed out of the plastic product and lose the connecting function, and the product quality is seriously influenced.

SUMMERY OF THE UTILITY MODEL

To the defect among the prior art, the utility model provides a metal embedded part to weaken the stress between cyclic annular metalwork and the plastic products spare, slow down the formation in gap, prolong holistic life.

The utility model provides a metal embedded part, which comprises an annular metal part, wherein a threaded hole for connection is arranged along the circumferential direction of the annular metal part; the cross section of the annular metal piece is circular, elliptical or polygonal, and a fillet is arranged between every two adjacent sides of the polygon.

Preferably, a fixing column is arranged along the circumferential direction of the annular metal piece, and the threaded hole is formed in the fixing column.

Because the surface of cyclic annular metalwork is equipped with the fillet and then forms glossy surface, directly set up the screw hole at cyclic annular metalwork and can cause the processing degree of difficulty big, the technical degree of difficulty is high. The threaded hole is conveniently formed by additionally arranging the fixing column on the annular metal piece, so that the processing difficulty is reduced.

Preferably, the connecting edge of the fixed column and the annular metal piece is provided with a round angle.

The edge angle formed on the connecting edge of the fixing column and the annular metal piece is avoided, the stress is further reduced, and the formation of a gap is slowed down.

Preferably, the threaded hole is parallel to the central axis of the annular metal member.

Preferably, the fixed column is equipped with eight, eight fixed column evenly distributed in cyclic annular metalwork and every fixed column all is equipped with the screw hole.

Eight screw holes make cyclic annular metalwork atress more even when connecting, connect simultaneously more firmly.

The beneficial effects of the utility model are embodied in:

the cross section of the annular metal piece in the equipment is circular, oval or polygonal with round corners and no edges, so that the outer surface of the annular metal piece is smooth and has no edges. With this equipment setting in plastic products spare with plastic products spare one-tenth an organic whole, after cyclic annular metalwork is connected the atress with other parts, because the smooth no edges and corners of cyclic annular metalwork surface, this will reduce the stress that cyclic annular metalwork produced to material goods spare greatly to slowed down the formation in the gap between cyclic annular metalwork and the plastic products spare, prolonged holistic life.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

As shown in fig. 1, the present embodiment provides a metal embedded part, which includes an annular metal part 1. The cross section of the annular metal piece 1 is circular, oval or polygonal, and a fillet is arranged between every two adjacent sides of the polygon. In the embodiment, the cross section is an ellipse, and after the annular metal piece 1 is fixed in the plastic product piece, because the outer surface of the annular metal piece 1 is smooth and has no edges and corners, the stress of the annular metal piece 1 on the plastic product piece is greatly reduced, so that the formation of a gap between the annular metal piece 1 and the plastic product piece is slowed down, and the service life of the whole body is prolonged. Wherein the plastic part may be a plastic pump, a plastic valve or other plastic part.

Because the surface of cyclic annular metalwork 1 is equipped with the fillet and then forms glossy surface, directly set up screw hole 3 at cyclic annular metalwork 1 and can cause the processing degree of difficulty big, and the technical degree of difficulty is high. Therefore, this embodiment is through addding fixed column 2 on cyclic annular metalwork 1 and conveniently seting up screw hole 3, reduces the processing degree of difficulty, and concrete structure is as follows:

along annular metalwork 1's circumference is equipped with fixed column 2, and fixed column 2 is equipped with eight, eight fixed column 2 evenly distributed in annular metalwork 1. Each fixing column 2 is provided with a threaded hole 3, and the threaded holes 3 are parallel to the central axis of the annular metal piece 1. The threaded hole 3 can be a blind hole or a through hole.

Because fixed column 2 and cyclic annular metalwork 1 integrated into one piece, can form at connection limit 4 between them and have sharp-pointed edge, in order to avoid this edge to increase the stress to the plastic products spare, every fixed column 2 and cyclic annular metalwork 1's connection limit 4 is equipped with the fillet, avoids forming the edge at fixed column 2 and cyclic annular metalwork 1's connection limit 4, further reduces stress, slows down the formation in gap.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
