Description

Multi-part bushing type adhesive holder Technical Field The invention relates to a multi-part lining-type glued or glued retainer which can be fixed in a part opening by means of gluing. The glue holder may be equipped with functional inserts before being glued in the component opening, so that the combination of the glue holder and the adapted functional insert may be adapted to different technical situations. In addition, the invention discloses a component having a component opening in which the above-mentioned adhesive holder with the functional insert is mounted. In addition, the invention discloses a method for installing the adhesive retainer in the component opening and a method for manufacturing the adhesive retainer according to the structure. Background The possibility of providing fixation in components made of low mechanical strength materials is a common problem in the prior art, these components or panels also being called lightweight panels. According to one material alternative, the lightweight panel is constructed of a honeycomb material, commonly referred to as a honeycomb panel. According to another structural alternative, these lightweight panels are sandwich panels or foam panels. Due to the construction material, the lightweight panel may not provide sufficient strength to directly attach, for example, threaded bolts to the lightweight panel. Accordingly, openings are typically provided in these lightweight panels, in which openings the component inserts are bonded. Such component inserts are, for example, threaded inserts made of metal, which are glued into the component openings, preferably blind holes. US 4,729,705 describes such a structure. In order to fix the threaded insert in the blind hole of the lightweight panel, the blind hole is partially filled with an adhesive. By inserting the threaded insert into the blind hole, the adhesive is displaced into the gap between the inner wall of the blind hole and the outer side region or outer side face of the threaded insert. A disadvantage of this displacement principle is that not all surfaces of the threaded insert and the blind hole that are intended to be wetted or sprayed with adhesive in order to achieve a reliable fixing of the threaded insert in the blind hole will be wetted or sprayed with adhesive. Another disadvantage is that the displaced adhesive is forced out of the blind hole and thus impairs the appearance of the threaded insert inserted in the blind hole. DE 102011 009 a1 describes an assembly system with two fittings, which can also be installed in lightweight panels. Such a fitting system is used in the furniture industry to provide a suitable application possibility for such a lightweight panel. The fitting is provided with an adhesive in its outer region, which adhesive can be activated by heating. For this purpose, the respective fitting is inserted into a blind hole or other suitable opening and rotated there at high speed. Heat is generated between the inner wall of the opening and the outside of the fitting with the adhesive due to friction, thereby activating the adhesive on the outside of the fitting. However, a reliable connection between the fitting and the inner wall of the part opening is only achieved if the inner diameter of the part opening exactly matches the outer diameter of the fitting, otherwise no heat is generated to activate the adhesive outside the fitting. Another disadvantage is that if the gap between the fitting and the inner wall of the component opening is too large, the amount of adhesive used to secure the fitting in the component opening is insufficient. In this case friction activates the adhesive, but the amount of adhesive available is insufficient to fill the gap between the fitting and the component opening. In addition, this document describes only an adapted connection between two fittings to be connected together. The connection is limited to a press-fit connection and/or a form-fit connection similar to the locking plug-in connection. Similar to the threaded inserts described above, this results in a lack of flexibility in terms of the connection possibilities of these fittings, since these connections are each limited by the internal structure of the respective fittings for connection. US 4,812,193 also describes a threaded insert to be glued in, for example, a honeycomb panel. The threaded insert is placed in the component opening to subsequently inject an adhesive into the gap between the threaded insert and the inner wall of the component opening. The adhesive overflows the threaded insert and fills the gap between the threaded insert and the inner wall of the component opening to secure the threaded insert in the component opening. For the purpose of guiding the adhesive for wetting/spraying the outer wall of the threaded insert, a plurality of disc-shaped radial webs are provided. The radial ribs extend in the circumferential direction and are evenly spaced from one an
