Detailed Description
The present invention will be described in further detail with reference to specific examples.
Examples
As shown in fig. 1 and 2, the utility model relates to a multi-functional bush of insert, including elastic body of revolution structure 10, body 10 includes the less upper portion of external diameter 1 and the great lower part 2 of external diameter that is demarcated by step face 3, and the surface of lower part 2 is equipped with external screw thread 21, and body 10's axial pierces through and divide into middle inner groove ring 4, is located the internal thread 22 of inner groove ring 4 below and is located the face of cylinder 11 of inner groove ring 4 top, and the internal diameter of inner groove ring 4 is greater than the internal diameter of face of cylinder 11, and the internal diameter of face of cylinder 11 is greater than internal thread 22's internal diameter. When the multifunctional bushing is to be assembled into a plate, the hexagon bolt 5 is needed. The specific operation mode is that the body 10 is manually screwed into the step hole of the plate 8, and the step surface 3 is opposite to the inner side plane of the step hole; then, a hexagon bolt 5 matched with the internal thread 22 is inserted from the lower part, the body 10 is pressed, and the hexagon socket head cap screw 7 is rotated and locked at the same time until the step surface 3 is mutually attached to the inner side plane of the step hole, and the concentricity of the step hole and the body 10 can be ensured at the moment. The upper end face of the body 10 is slightly lower than the upper surface of the plate 8 by 0.2mm, so that the overall appearance is flat, the appearance is attractive, the flatness of the upper surface of the plate 8 is not influenced, and finally the hexagon socket head cap screw 7 is removed, so that the installation of the multifunctional lining on the plate 8 is completed, the installation is rapid, convenient and high in positioning precision, and meanwhile, the processing of the plate 8 is simplified.
Example 1: assembled with connecting pins 6
When the multifunctional bushing is completely fixed to the plate 8, the connecting pin 6 is also screwed into the internal thread 22 from above. Because the inner diameters of the cylindrical surface 11 and the inner groove ring 4 are larger than the inner diameter of the internal thread 22, the connecting pin 6 cannot be blocked when passing through from the upper part and only can be meshed with the internal thread 22, so that the multifunctional bushing can tighten the connecting pin 6 to finish fixing.
Example 2: assembled with expansion pins 7
When the multifunctional bushing is completely fixed to the plate 8, the expansion pin 7 is also engaged with the internal thread 22 from above. The expansion pin 7 can penetrate other parts, the expansion head is located at the inner groove ring 4, when the expansion pin 7 assembles another part above the plate 8, the expansion head can be expanded naturally to abut against the inner groove ring 4, the separation of the expansion head can be blocked by the smaller cylindrical surface 11, and the assembled structure cannot be separated. Because the expansion head is four-sided, concentricity is also ensured with the inner groove ring 4.
Therefore, the multifunctional bushing can meet the use requirements of the connecting pin 6 and the expansion pin 7 at the same time, the installation stability is high, and the later maintenance cost is low.
As shown in fig. 1, the lower edge of the lower part 2 is formed as a downward inclined tapered surface 23. The lower tapered surface 23 allows a gap to be left between the edge of the lower portion 2 of the body 10 and the mounting hole of the plate 8, which is convenient when replacing a damaged multifunctional bushing.
As shown in fig. 1, the upper edge of the upper part 1 is tapered upward 12. The upper tapered surface 12 can facilitate pressing the body 10 into the mounting hole of the plate 8 without needing to take a long time to align the position.
As shown in fig. 1, the upper edge of the cylindrical surface 11 has a chamfered surface 13. The chamfered surface 13 allows the connecting pin 6 or the expansion pin 7 to more quickly locate the cavity and facilitate its insertion into the hollow portion of the body 10.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
