Description
Technical field
The utility model is related to a kind of connection structures, and in particular to a kind of plastic part and metalwork connection structure.
Background technology
The lightweight of automobile is increasingly taken seriously, and the light-weight design of the wherein carry out system of engine is not also broken into
It is ripe.The gas handling system of plastics is mostly used at present, but connection metal connecting piece is also needed on plastic part, the connection of traditional metal
The connection of part and plastic casing is generally inserted into metalwork, by two using heating insertion process that is, by heating plastic part
Person connects.But it is not only complex for operation step by the connection type of this heating insertion process, working efficiency is influenced, and need
Using more plastic material, cost increases, and manufacture difficulty is higher, and is easy there are problems that connection loosely.
Utility model content
The purpose of this utility model is exactly to solve the above-mentioned problems and provides a kind of plastic part and metalwork connection structure.
The purpose of this utility model is achieved through the following technical solutions：
A kind of plastic part and metalwork connection structure, including plastic part and metalwork, the plastic part are cylindrical shell
Structure, the metalwork are cylindrical structure, and the plastic part is set on metalwork, and the side of the metalwork is equipped with ring
Shape slot, the inner wall side of the plastic part are equipped with the matched annular lug of annular groove with metalwork, the convex annular of plastic part
Block is caught in the annular groove of metalwork, compared with using the connection type of heating insertion process, using plastic part and metalwork phase
The connection type mutually buckled, operating procedure is simple, and work efficiency is high, need not use more plastic material, cost reduction, and
Connect robust.
Further, the shaft end of the metalwork is equipped with the threaded hole for connection, and the shaft end of metalwork is equipped with spiral shell
Pit can facilitate the connection with other component, to easily by metalwork and plastic part assembly connection.
Further, the depth of the annular groove of the metalwork is 3-5mm, width 1-10mm, the annular groove of metalwork
Depth and width it is suitable, it is loosely or excessive to avoid being blocked due to too small, increase manufacturing cost and influence metalwork
The performance of itself.
Further, the projecting height of the annular lug of the plastic part is less than the depth of annular groove, in this way, can make modeling
Materials and parts inner wall is fitted tightly over the top and the bottom of metalwork.
Further, the section of the annular groove and annular lug is square or V-arrangement, is conducive to assemble.
Further, the plastic part is integrated injection molding, and plastic part has certain elasticity, can pass through interference
Cooperation is easily connect with metalwork.
Compared with prior art, the utility model is by using the cold quick connection looked into technique and realize plastic part and metalwork
Assembly, compared with the slotting technique of traditional heat, the plastic material used is few, at low cost, and the consume of no plastic material, manufacture difficulty is low,
And assembly connection is secured, should not fall off.

Specific implementation mode
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
Embodiment 1
A kind of plastic part and metalwork connection structure, as shown in figure 3, including plastic part 4 and metalwork 1, such as Fig. 1,2 institutes
Show, plastic part 4 is cylindrical shell structure, and metalwork 1 is cylindrical structure, and plastic part 4 is set on metalwork 1, the side of metalwork 1
Face is equipped with annular groove 2, and the inner wall side of plastic part 4 is equipped with the 2 matched annular lug 5 of annular groove with metalwork 1, plastic part
4 annular lug 5 is caught in the annular groove 2 of metalwork 1, and the shaft end of metalwork 1 is equipped with the threaded hole 3, Ke Yifang for connection
Just with the connection of other component, to easily by metalwork 1 and 4 assembly connection of plastic part.In the present embodiment, metalwork 1
The depth of annular groove 2 is 5mm, width 10mm, and the projecting height of the annular lug 5 of plastic part 4 is less than the depth of annular groove 2,
In this way, 4 inner wall of plastic part can be made to be fitted tightly over the top and the bottom of metalwork 1.The section of annular groove 2 and annular lug 5 can be in
Rectangular or V-arrangement, the present embodiment are rectangular, and plastic part 4 is integrated injection molding, and plastic part 4 has certain elasticity, can pass through
Interference fit is easily connect with metalwork 1.
The utility model realizes that plastic part 4 is linked and packed with the quick of metalwork 1 by using cold technique of looking into, and adds with using
The connection type of hot insertion process is compared, and the connection type mutually buckled using plastic part 4 and metalwork 1, operating procedure is simple,
Work efficiency is high, need not use more plastic material, and the consume without plastic material, and manufacture difficulty is low, assembly connection jail
Admittedly should not fall off.
