Detailed Description
The following describes embodiments of the present invention in detail with reference to fig. 1 to 5.
Locomotive door observation glass, including the door frame skeleton 1 of cavity door frame shape and bond the glass 2 on 1 terminal surface of door frame skeleton, its characterized in that: door frame skeleton 1 be close to the inner wall of terminal surface on be equipped with the anti-overflow that holds the viscose and glue ring groove 11, the location has rubber strip 3 on the anti-overflow glues ring groove 11, glass 2 and 3 laminating of rubber strip to through the viscose in the anti-overflow glue ring groove 11 and door frame skeleton 1 bonding.
Above the door observe glass with anti-overflow glue ring groove 11 empty receive the viscose, make the viscose have accommodation space, can not overflow from 2 edges of glass when bonding glass, the problem of overflowing glue appears in the observation glass installation that has solved prior art and gone on easily, avoid overflowing the influence of gluing to glass visual effect. Rubber 3 is glued and is fixed a position on anti-overflow gluey annular 11, and with laminating observation glass, 2 and door frame skeleton 1 are observed in the connection of viscose 4, and rubber strip 3 not only plays sealed effect to viscose 4, plays buffering damping effect to glass 2 moreover, makes locomotive door observation glass have good thermal-insulated, give sound insulation and damping performance.
Wherein, anti-overflow glue annular 11 set up along the hoop at 1 inner wall of door frame skeleton, the hem 12 of stretching out 15 free ends of limit 15 and shaping that have the level to stretch out on the inner wall of door frame skeleton 1, hem 12 is located door frame skeleton 1 cavity inner chamber, door frame skeleton 1 inner wall, stretch out limit 15 and hem 12 surround and form anti-overflow glue annular 11, 3 location of rubber strip are on hem 12. As shown in the figure, the glass 2 is attached to the rubber strip 3, and the rubber strip 3 just can prevent the adhesive in the anti-overflow adhesive ring groove 11 from overflowing from the folded edge 12.
The glue overflow preventing ring groove 11 is composed of a glue containing groove 11.1 close to the inner wall of the door frame framework 1 and a glue overflow groove 11.2 arranged on the inner side of the glue containing groove 11.1, the height of the glue overflow groove 11.2 is lower than that of the glue containing groove 11.1, and a step surface 11.3 is formed between the glue containing groove 11.1 and the glue overflow groove 11.2. The glue containing groove 11.1 and the glue overflow groove 11.2 are arranged in a step type, when the glue containing groove 11.1 is filled with glue, the glue can flow into the glue overflow groove 11.2, the glue has a certain flowing space, the glue can not overflow from the edge directly, and the glue overflow phenomenon of the glass bonding edge can be effectively avoided.
The rubber strip 3 is provided with a positioning groove 31 corresponding to the folding edge 12, the folding edge 12 extends into the positioning groove 31 to position the rubber strip 3, the depth of the positioning groove 31 is smaller than the height of the folding edge 12, and the folding edge 12 is adhered to the wall of the positioning groove 31 and extends into the glue overflow groove 11.2. Hem 12 is difficult for droing with positioning groove 31 cell wall adhesion, and thoroughly seal up the space between rubber strip 3 and the hem 12, guarantee that the glue solution can not be excessive, hem 12 and positioning groove 31 cooperation back, rubber strip 3 not with stretch out 15 contacts on the limit, there is the gap between the two, hold unnecessary glue solution inflow overflow glue groove 11.2 when gluey groove 11.1 is full of by the glue solution, fill overflow glue groove 11.1 and enter into to rubber strip 3 and stretch out between the limit 15, prevent that the glue solution from spilling over to 2 edges of glass promptly, strengthen rubber strip 3 and door frame skeleton 1's bonding strength again, the life of extension rubber strip.
Wherein, the width of the rubber strip 3 extending into the glue overflow groove 11.2 is less than the width of the glue overflow groove 11.2. The rubber strip 3 does not fill the glue overflow groove 11.2, so that the glue solution can flow into the glue overflow groove 11.2 along the current direction after the glue containing groove 11.1 is filled with the glue solution, the flowing space of the glue solution is larger, and the glue overflow phenomenon can be effectively prevented.
The outer edge of the glass 2 is separated from the inner wall of the door frame framework 1 to form a glue inlet gap 13, and the glue inlet gap 13 is communicated with the glue containing groove 11.1. And after the glass 2 is attached to the rubber strip 3, injecting glue solution from the glue inlet gap 13 by using a glue gun, wherein the glue solution injection operation is simple, the glue solution is injected from the glue inlet gap 13, and the glue solution is cured to form a glue 4 to fill the anti-overflow glue ring groove 11.
The width of the glue inlet gap 13 is smaller than that of the glue containing groove 11.1, and the width of the glue overflow groove 11.2 is larger than that of the glue inlet gap 13 and smaller than that of the glue containing groove 11.1. Effectively increase the bonding area of 2 edges of glass and door frame skeleton 1, improve glass 2's bonding stability.
The end face of the door frame framework 1 is provided with an end face flanging 14 which is turned out by 90 degrees, and the outer surface of the glass 2 is flush with the outer surface of the end face flanging 14. The flange 14 is used for installing the locomotive door observation glass, and the outer surface of the glass 2 is flush with the outer surface of the end surface flange 14, so that installation interference is avoided.
The technical solutions of the embodiments of the present invention are completely described above with reference to the accompanying drawings, and it should be noted that the described embodiments are only some embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
