Model utility content
The utility model embodiment, by providing a kind of coupling member for tubular metal part and cast resin piece, is connected the technical problem of the less stable existed with the button-type between tubular metal part in order to resin piece in prior art.
The utility model embodiment provides a kind of coupling member for tubular metal part and cast resin piece, comprising:
Cast resin piece;
Protective metal shell, is arranged at described cast resin piece peripheral, has a wedge shape space between described protective metal shell and described cast resin piece;
Briquetting, be arranged in described wedge shape space, the tapering of described briquetting is less than Self-locking angle;
Tubular metal part, is connected with described protective metal shell, and end face contacts with described briquetting.
Alternatively, described cast resin piece has been nested with inner liner metal ring, and the position at described inner liner metal ring place corresponds to the position that described briquetting contacts with described cast resin piece.
Alternatively, described tubular metal part and described protective metal shell are threaded connection.
Alternatively, described tubular metal part is specifically fabricated from iron.
Alternatively, described tubular metal part is specifically made of copper.
Alternatively, described cast resin piece is specifically made up of glass fiber resin.
Alternatively, described cast resin piece is specifically made up of carbon fibre resin.
One or more technological scheme in the utility model embodiment, at least tool has the following advantages or beneficial effect:
1, owing to have employed in the wedge shape space that briquetting is arranged between protective metal shell and cast resin piece, and the tapering of briquetting is less than the technological scheme of Self-locking angle, so pulling force suffered between tubular metal part and cast resin piece is less than the activity frictional force between briquetting and cast resin piece, thus define the effect of being fixedly connected, ensure that the stability of the connection between tubular metal part and cast resin piece, thus the button-type solved in prior art between resin piece with tubular metal part is connected the technical problem of the less stable existed.
2, the technological scheme of inner liner metal ring is nested with owing to have employed cast resin piece corresponding to the position that contacts with described cast resin piece at briquetting, avoid that the stressing conditions being out of shape, making connected element because cast resin piece is subject to the extruding of briquetting changes and situation that the coupling member that causes the utility model embodiment to provide loses the effect of being fixedly connected occurs, ensure that the stability of the coupling member that the utility model embodiment provides.
Accompanying drawing explanation
The structural representation of the coupling member for tubular metal part and cast resin piece that Fig. 1 provides for the utility model embodiment;
The schematic cross-section of the coupling member for tubular metal part and cast resin piece that Fig. 2 provides for the utility model embodiment.
Embodiment
The utility model embodiment, by providing a kind of coupling member for tubular metal part and cast resin piece, is connected the technical problem of the less stable existed with the button-type between tubular metal part in order to resin piece in prior art.
Please refer to Fig. 1, the schematic diagram of the coupling member for tubular metal part and cast resin piece that Fig. 1 provides for the utility model embodiment, as shown in Figure 1, the coupling member for tubular metal part and cast resin piece that the utility model embodiment provides comprises:
Cast resin piece 5;
Protective metal shell 2, is arranged at cast resin piece 5 peripheral, has a wedge shape space between protective metal shell 2 and cast resin piece 5;
Briquetting 3, is arranged in wedge shape space, and the tapering of briquetting 3 is less than Self-locking angle;
Tubular metal part 1, is connected with protective metal shell 2, and end face contacts with briquetting 3.
Can find out, owing to have employed in the wedge shape space that briquetting is arranged between protective metal shell and cast resin piece, and the tapering of briquetting is less than the technological scheme of Self-locking angle, so pulling force suffered between tubular metal part and cast resin piece is less than the activity frictional force between briquetting and cast resin piece, thus define the effect of being fixedly connected, ensure that the stability of the connection between tubular metal part and cast resin piece, thus the button-type solved in prior art between resin piece with tubular metal part is connected the technical problem of the less stable existed.
In specific implementation process, cast resin piece 5 has been nested with inner liner metal ring 4, the position at inner liner metal ring 4 place corresponds to the position that briquetting 3 contacts with cast resin piece 5, thus avoid because cast resin piece is subject to the extruding of briquetting and be out of shape, the stressing conditions of connected element is changed and situation that the coupling member that causes the utility model embodiment to provide loses the effect of being fixedly connected occurs, can find out, the technological scheme of inner liner metal ring is nested with owing to have employed cast resin piece corresponding to the position that contacts with cast resin piece at briquetting, ensure that the stability of the coupling member that the utility model embodiment provides.
