Description

TECHNICAL FIELD

[0001] The utility model relates to a cabinet accessory field especially relates to a pull handle free steel wood integrated door panel. BACKGROUND

[0002] Traditional high-grade pure solid wood door cost is high, weight is heavy, in addition, solid wood door expands and extrudes the door mouth when temperature is high, easily causes solid wood door wear and tear, shrinks when temperature is low, leads to door not to close tightly, and hot expansion cold contraction easily leads to solid wood door to crack. SUMMARY

[0003] The utility model discloses a pull handle free steel wood integrated door panel to solve the above technical problem.

[0004] In order to realize above object, the utility model discloses a technical scheme for providing pull handle free steel wood integrated door panel, including steel sheet, aluminium honeycomb layer and solid wood board, the front wall of steel sheet is concave to the back and forms aluminium honeycomb layer installation groove, the depth of aluminium honeycomb layer installation groove is consistent with the thickness of aluminium honeycomb layer, aluminium honeycomb layer is installed in aluminium honeycomb layer installation groove, and the back wall of aluminium honeycomb layer is bonded with the bottom of aluminium honeycomb layer installation groove, the back wall of solid wood board is bonded with the front wall of aluminium honeycomb layer, and the periphery of the back wall of solid wood board is bonded with the front wall of steel sheet on the outside of aluminium honeycomb layer installation groove, the upper end of the back wall of steel sheet is provided with the inclined surface of the upper front inclination, and the periphery of solid wood board is located on the inside of the periphery of steel sheet.

[0005] Preferably, the outer side wall of the aluminium honeycomb layer is bonded with the inner side wall of the aluminium honeycomb layer installation groove.

[0006] Preferably, the front wall of the steel sheet is convex to form a limiting boss above the aluminium honeycomb layer installation groove, and the upper end of the solid wood board is connected with the lower wall of the limiting boss. The limiting boss plays a limiting and positioning role.

[0007] Preferably, the front wall of the limiting boss is located in front of the front wall of the solid wood board. The limiting boss prevents the solid wood board from colliding and plays a role of protecting the solid wood board.

[0008] Preferably, the steel sheet, the aluminium honeycomb layer and the solid wood board are all quadrangular.

[0009] Unlike the prior art, the periphery of the solid wood board is located on the inside of the periphery of the steel sheet, the solid wood board is exposed, plays an aesthetic effect, the steel sheet has high stability and is not easy to deform, can avoid affecting the normal opening and closing of the door panel due to thermal expansion and cold contraction of the solid wood board, the aluminium honeycomb layer in the middle layer is light in weight, can reduce the overall weight of the door panel, also has the effects of fireproofing and moisture-proofing, in addition, the steel sheet and the honeycomb aluminium layer replace high-end solid wood, also save manufacturing cost.

[0010] The utility model will become more clearly through the following description and in conjunction with the drawings, these drawings are used to explain the utility model's embodiment. BRIEF DESCRIPTION OF DRAWINGS
