Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
See fig. 1-4.
A metal insert comprises an insert body 1 and an outer shell 2 connected to the outer side of the insert body 1, wherein a first anti-rotation bulge 3 is connected to the end part of the insert body 1; the outer side surface of the insert body 1 is provided with a dovetail ring groove 4, and the inner side of the insert body is provided with an anti-drop ring groove 5; the end of the outer shell 2 is connected with a second anti-rotation bulge 6.
Specifically, the first anti-rotation protrusions 3 are 6 in total and are uniformly distributed along the end face of the insert body 1 in the radial direction at equal angles.
Specifically, the first rotation preventing protrusion 3 is shaped like an isosceles trapezoid.
Specifically, the total number of the second anti-rotation protrusions 6 is 6, and the second anti-rotation protrusions are uniformly distributed along the end face of the outer shell 2 at equal angles in the radial direction.
Specifically, the second anti-rotation protrusion 6 is square.
Specifically, the insert body 1 and the outer shell 2 are integrally formed.
Description of the principle of use: the outer side surface of the insert body 1 of the utility model is provided with a dovetail ring groove 4, the inner side is provided with an anti-loosening ring groove 5, when the injection molding main body is injected on the insert body 1, the injection molding main body can not move up and down, and is difficult to loosen (refer to figure 3); the end part of the insert body 1 is connected with a first anti-rotation bulge 3, the end part of the outer shell 2 is connected with a second anti-rotation bulge 6, when the injection molding main body is injected on the insert body 1, the injection molding main body can form a first clamping groove 11 corresponding to the first anti-rotation bulge 3 and a second clamping groove 12 (refer to figure 2) corresponding to the second anti-rotation bulge 6, the first anti-rotation bulge 3 is positioned in the first clamping groove 11, the second anti-rotation bulge 6 is positioned in the second clamping groove 12, the injection molding main body cannot rotate around the insert body 1, and the connection is very firm; the first anti-rotation bulge 3 is in an isosceles trapezoid shape, two side surfaces of the first anti-rotation bulge are inclined planes, so that a contact surface between the first anti-rotation bulge and the injection molding main body can be increased, and the anti-rotation effect is better; the utility model discloses forked tail annular 4 is two altogether, in order to make its anticreep effect better, can open again on 1 lateral surface of inserts body has an outer anticreep annular 7.
The utility model discloses can part internal thread metal inserts and outer silk metal inserts, internal thread metal inserts can refer to figure 1 and figure 3, and outer silk metal inserts can refer to figure 4.
