Detailed Description
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be further described below.
As shown in fig. 1 and 2, the utility model provides a hot melt adhesive plug, which comprises a plug body 1 and a hot melt adhesive ring 2;
the middle part of the plugging cover body 1 is a columnar plug body, a circle of skirt edges 22 are arranged on the periphery of the upper surface of the columnar plug body, a plurality of elastic clamping feet 21 are arranged on the side surface of the columnar plug body, and the elastic clamping feet 21 are at the same height and are arranged on the side surface of the columnar plug body at equal intervals; as shown in fig. 3, in the installation stage, the blanking cover body 1 is inserted into a process orifice of a metal plate, and the metal plate is pre-fixed between the elastic clamping legs 21 and the skirt edge 22, so as to realize pre-installation. The side of the columnar plug body is provided with a concave part at the position opposite to the elastic clamping pin 21, the elastic clamping pin 21 is convenient to contract in the pressing stage, the insertion force of a product is reduced, the installation is convenient, and the installation efficiency of the product is improved.
As shown in fig. 2, the hot melt adhesive ring 2 is welded between the outer ring of the skirt 22 and the side surface of the columnar plug body in an injection molding manner, and after the metal plate of the vehicle body is baked at high temperature, the hot melt adhesive can realize complete sealing and bonding between the skirt 22 and the metal plate around the process hole, thereby realizing the technical effects of water resistance and dust resistance.
In this embodiment, as shown in fig. 1 and fig. 3, the upper surface and the lower surface of the columnar plug body are both of a glue-drawing structure, so that the total material cost and weight of the product are reduced, the injection molding time of the product is shortened, the product has good elasticity, and the installation of the product is facilitated.
In the embodiment, the solid thickness of the middle part of the columnar plug body is 4-5mm, and the product has good sound insulation and noise reduction effects through limiting the thickness.
In this embodiment, as shown in fig. 4, a schematic diagram of a mounting structure of a product and a metal plate is shown, and in order to ensure the product effect, the hot melt adhesive part is made of EVA hot melt adhesives; and the material of the part of the plugging cover body 1 is toughened PA6. In the installation stage, the hot melt adhesive blanking cover is inserted into the process hole of the metal plate, so that the metal plate is fixed between the elastic clamping foot 21 and the skirt edge 22, pre-installation is completed, then, the automobile body is baked at a high temperature (the process of baking paint on the outer surface of the product is necessary, the temperature can reach the melting point of the hot melt adhesive), the hot melt adhesive can be melted into a liquid state, after the baking of the automobile body is finished, the hot melt adhesive starts to be solidified from the liquid state, and the blanking cover and the automobile body can be completely bonded and sealed after solidification, so that the waterproof and dustproof effects are achieved.
The foregoing is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any person skilled in the art will make any equivalent substitution or modification to the technical solution and technical content disclosed in the utility model without departing from the scope of the technical solution of the utility model, and the technical solution of the utility model is not departing from the scope of the utility model.
