Plate frame structure of polyurethane foam board

Abstract

The invention discloses a plate frame structure of a polyurethane foam board, which belongs to a decorative or electrical board. The plate frame structure comprises a frame body, a panel and a soleplate, wherein the frame body consists of a panel supporting seat, a soleplate supporting seat and a transition supporting seat. The plate frame structure is characterized by also comprising a decoration protective strip, wherein one side of the decoration protective strip is provided with a pressing panel, an embedded flange and an embedded foot. The upper part of the inner side of the transition supporting seat is provided with an embedded flange groove and the lower part of the outer side is provided with an embedded foot groove. The pressing panel corresponds to the edge part of the panel. The embedded flange is embedded in the embedded flange groove. The embedded foot is embedded in the embedded foot groove. The corresponding groove wall of the embedded flange groove is provided with a first inverse hook tooth. Wall bodies on the two sides of the embedded flange are provided with second inverse hook teeth. The first and second inverse hook teeth cooperate with each other. The decoration protective strip of the plate frame structure can be combined with the transition supporting seat without any fastener. The pressing panel covers the foaming agent escaping to the edge part of the panel. A draw hook plate strengthens the whole combination effect between the frame body and a polyurethane foam layer.

Description

technical field [0001] The invention belongs to the technical field of decoration and electrical boards, and in particular relates to a board frame structure for polyurethane foam boards. Background technique [0002] The plate frame structure of the polyurethane foam plate that is applied to decoration, furniture, refrigerator and air conditioner etc. in the prior art is by image 3 As shown, it includes a frame body 1, a panel 2 and a bottom plate 3 composed of a panel support seat 11, a bottom plate support seat 12 and a transition support seat 13. The panel support seat 11 is combined with the top of the transition support seat 13, and the bottom plate support seat 12 is combined with At the bottom of the transition support seat 13, and the surface, the bottom plate support seat 11, 12 and the transition support seat 13 are connected to each other as one, and the edge of the panel 2 rests in the step concave cavity 111 on the upper surface of the panel support seat 11 , ...

AI Technical Summary

Problems solved by technology

But there is following technical problem: because step cavity 111 and the edge position of panel 2 have the fit gap that can't be eliminated, when forming polyurethane layer 4 by foaming, foaming agent will be from the step of panel 2 and panel support seat 11 Escape from the gap of the joint part of the concave cavity 111, and contaminate the surrounding edges of the surface of the panel 2, affecting the quality of the polyurethane foam board

However, the applicant believes that the above-mentioned structure has the problem of taking care of one thing and losing the other. The so-called taking care of this only takes into account the covering of the foam material on the edge of the surface of the panel 2 by the 7-shaped cover plate. The so-called loss of the other means , because the tail of the core-pulling aluminum rivet is exposed outside the 7-shaped cover plate, the periphery of the panel 2 of the polyurethane foam board cannot reflect the overall smooth and smooth effect, and the use of the board body is limited, for example, it cannot be used as an electrical board

[0003] In addition to the above shortcomings, there is also the problem that the bonding effect between the polyurethane layer 4 and the frame body 1 is fragile, and it is easy to make the gap between the frame body 1 and the polyurethane layer 4 resulting in dismemberment
