Description

Door plate structure for preventing paint surface from cracking

Technical Field

The utility model relates to a door plate structure, in particular to a door plate structure capable of preventing a painted surface from cracking, and belongs to the technical field of door plate manufacturing.

Background

The solid wood door plate is made of natural logs or solid wood laminated materials (also called solid wood finger joint materials or solid wood tooth joint materials) from forests and is scientifically processed through the procedures of drying, blanking, planing, tenoning, drilling, high-speed milling, assembling, polishing, painting and the like. The wooden doors of the family on the market can be roughly divided into three types: all-solid wood door, solid wood composite door and mould pressing door. The decorative door is a precious luxurious decorative door made of solid wood and is divided into three styles of full wood, half glass and full glass. The material is basically selected from various tree species such as black walnut, red walnut, sapelli, cherry, fraxinus mandshurica, sleeve wood, oak, and the like. The processing technology is seen to be two types of full logs and finger-jointed wood, the finger-jointed wood refers to wood obtained by sawing and finger-jointing the logs, the performance of the wood is much more stable than that of the logs, and the door can be ensured not to deform practically. The solid wood door gives people a sense of stability and elegance. Also known as solid core doors. The frame is made of solid wood, the front side and the back side of the door surface are adhered by wood boards, and the inner layer is filled with heat-insulating materials. The solid wood composite door has more patterns, has the functions of no deformation and no cracking, has sound insulation which is almost the same as that of the whole solid wood door, particularly has the advantages of lower price than that of the whole solid wood door and visual effect of the whole solid wood door, so that the solid wood composite door has good market quotation, and can not be consumed by every salary family after all, thereby meeting the requirements of common family decoration and being widely adopted. Strictly speaking, the solid wood composite door can replace a solid wood door in the decoration position of a common family as long as the solid wood composite door has good quality and delicate workmanship. Also called a plywood door, the same frame is made of solid wood and is formed by bonding two sheets of mould pressing door skin plates with decorations and imitated wood grains, and the finished product is mainly manufactured by mechanical pressing, so the mould pressing door is called in the industry. The door has low cost, light weight and low price, and is suitable for ordinary salary families. However, many molded doors on the market are poor in quality, have a decorative appearance like a model, seem to be high-grade and smooth, and are actually made of artificial boards, and break and deform after a long time. Among the prior art, the problem that the wood door plant exists lies in that the phenomenon of paint appears easily in the 45 concatenation combination parts of wood doorjamb, leads to the difference in height on the appearance comparatively obvious. Therefore, further improvements are desired.

Preferably, the first slot and the second slot are distributed in a step shape; and a vertical flange is arranged on one backlight side of the frame.

Preferably, the vertical flange is arranged at one side of the second slot; the back card strip comprises an insertion body and a contact body.

Preferably, the outer end surfaces of the insertion body and the contact body are both arc surfaces; the insert body is positioned in the second slot; the thickness of the insert body is smaller than that of the contact body; the contact body is abutted against the door core plate.

According to the utility model, the first mortise and the second mortise are arranged at the end parts of the frame and the vertical frame, and the frame and the vertical frame are connected through the right-angle sealed edge instead of being directly connected, so that the extrusion and deformation of the frame and the vertical frame caused by deformation can be greatly reduced; simultaneously, the core supports through the backpressure strip and leans on in the region that frame and mullion are constituteed, and it is convenient to change, can effectively solve traditional wood doorjamb 45 degrees combination paint fracture phenomenon.
