Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the invention easy to understand, the invention is further explained below with reference to the specific embodiments, but the following embodiments are only the preferred embodiments of the invention, not all. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention. The experimental methods in the following examples are conventional methods unless otherwise specified, and materials, reagents and the like used in the following examples are commercially available unless otherwise specified.

Example (b):

as shown in fig. 1, 2, 3 and 4, a novel riveting sleeve comprises a riveting sleeve body 1 and an interface 2, wherein a riveting mechanism is arranged outside the riveting sleeve body 1;

the riveting mechanism comprises a circular pipe 12, the circular pipe 12 is fixedly installed on the end portion of the riveting sleeve body 1, straight-thread teeth 13 are fixedly installed outside the circular pipe 12, a riveting ring 14 is fixedly installed on the end portion of the circular pipe 12, and convex rings 15 are arranged on the end portions of the two sides of the riveting ring 14.

Be provided with the interface via hole 3 that supplies the installation of riveting sleeve body 1 block on the interface 2, fixed mounting has the circular cover 11 that is used for spacingly on the tip of riveting sleeve body 1, same circular preset hole 16 has been seted up in circular pipe 12 and the ring 14 of riveting, circular pipe 12 has seted up the edge bevel of forty-five degrees with riveting round pipe 12 on 14 contact position, the external diameter requirement of straight line tooth 13 is greater than interface via hole 3, straight line tooth 13 internal diameter requirement is less than interface via hole 3, straight line tooth 13 intensity is greater than interface via hole 3.

When the riveting sleeve body 1 is installed on equipment, an interface via hole 3 needs to be formed on an interface 2, the requirement of the interface via hole 3 is that the outer diameter of a straight-line tooth 13 is required to be larger than that of the interface via hole 3, the requirement of the inner diameter of the straight-line tooth 13 is smaller than that of the interface via hole 3, the strength of the straight-line tooth 13 is larger than that of the riveting sleeve body 1, then one end of the riveting sleeve body 1, which is provided with the straight-line tooth 13, is aligned with the interface via hole 3 on the interface 2, pressure in a corresponding direction is applied to a circular sleeve 11, so that a circular pipe 12 and a riveting ring 14 on the riveting sleeve body 1 move in the corresponding direction in the interface via hole 3, and due to the limitation of the diameter of the straight-line tooth 13, in the process that the circular pipe 12 moves in the interface via hole 3, the interface via hole 3 is propped open, and is extruded by the straight-line tooth 13 and the riveting sleeve body 1 to deform, and the riveting ring 14 and a convex ring 15 enter the interface 2, under the effect that interface 2 extrudees, protruding circle 15 can receive corresponding reverse pressure, takes place deformation, rivets the combination of circle 14 and straight line tooth 13 and forms the concave circle, and the material in the extrusion interface 2 can block in the concave circle, rivets sleeve body 1 like this and breaks away from just needing great power from interface 2, is difficult to break away from, later with the screw from the circular preset hole 16 in turn round into to the installation to the screw is realized.

The working principle is as follows:

the first step is as follows: when the riveting sleeve body 1 is installed on equipment, an interface through hole 3 needs to be formed in an interface 2, the requirement of the interface through hole 3 is that the outer diameter of a straight-line tooth 13 is required to be larger than that of the interface through hole 3, the requirement of the inner diameter of the straight-line tooth 13 is smaller than that of the interface through hole 3, and the strength of the straight-line tooth 13 is larger than that of the riveting sleeve body 1.

The second step is that: the one end that will rivet sleeve body 1 and install straight line tooth 13 aligns with interface via hole 3 on the interface 2, through applying the pressure that corresponds the direction to circular cover 11, let circular pipe 12 and riveting ring 14 on riveting sleeve body 1 do the removal that corresponds the direction in interface via hole 3, and because the restriction of straight line tooth 13 diameter, in the in-process that circular pipe 12 removed in interface via hole 3, interface via hole 3 can be strutted, it takes place deformation to be extruded by straight line tooth 13 and riveting sleeve body 1, after riveting ring 14 and protruding circle 15 get into interface 2, under interface 2 extruded effect, protruding circle 15 can receive corresponding reverse pressure, take place deformation, riveting ring 14 and straight line tooth 13 combination form the concave circle, the material in the extrusion interface 2 can block in the concave circle, riveting sleeve body 1 breaks away from just need great power from in the interface 2 like this, break away from.

The third step: the screws are then torqued from within the circular pre-holes 16 to effect the mounting of the screws.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art.
