Description

Technical Field

[0001] The utility model relates to the technical field of door leaves, in particular to a graphite homogeneous plate composite wooden door leaf. Background Art

[0002] Solid wood composite doors have less deformation, cracking, shrinkage and expansion, and the price is relatively low, which makes solid wood composite doors have a large market.

[0003] For example, a wood-filled fireproof door leaf disclosed in patent number CN219316826U, although the disclosed fireproof door leaf adopts a double-layer structure of the fireproof core board with a smaller weight, and the interlayer is conducive to blocking the transfer of high temperature, the interlayer is formed by the support of a steel frame, and the steel frame plays a structural support role, thereby greatly reducing the weight and solving the problem of the heavy fireproof door. However, when this type of fireproof door leaf needs to be installed with a door lock, the installation of the door lock requires excavating a lock groove in the door leaf, that is, the lock groove needs to be excavated on the core board. Therefore, the structural strength of the core board where the door lock is installed is greatly reduced, which affects the actual use of the door leaf.

[0004] As a new type of door core material, graphite homogeneous plate has better material performance, but it also has the problem of insufficient structural strength at the door lock installation point, so it needs to be improved. Utility Model Content

[0030] The decorative panel 110 is made of a medium-density fiberboard with wood veneer, so that it is preferably decorated by carving, painting, etc. on the decorative panel 110 to make it more beautiful and better tactile. In actual use, the decorative panel 110 is compositely bonded to the wooden frame 100 and the outer surface of the wooden board 210 with environmentally friendly glue, and the size of the decorative panel 110 is suitable for the size of the wooden frame 100;

[0031] In this embodiment, the decorative panel 110 and the wooden board 210 have notches corresponding to the notches 201 reserved for installing the door lock 120, so that it is convenient to install the door lock 120 on the wooden door leaf;

[0032] Among them, by setting the reinforcing component, it is possible to strengthen the strength of the core plate 200 at the side wall of the notch 201, that is, to strengthen the installation strength of the door lock 120 at one side of the core plate 200, so as to avoid the strength of the wooden door leaf being reduced due to the installation of the door lock 120, thereby affecting its actual use;

[0033] Among them, through the setting of the installation opening 231, when the door lock 120 is installed, the lock body of the door lock 120 can be extended into the slot 201 through the installation opening 231.

[0035] Among them, the inner side wall of the wooden frame 100 protrudes outward to form a convex portion 311, that is, the inner side walls of the first wooden block 230a and the second wooden block 230b both protrude outward to form a convex portion 311, and the opposite ends of the convex portion 311 are arranged in an inclined surface, thereby making the convex portion 311 not interfere with the splicing between the first wooden block 230a and the second wooden block 230b, and the surrounding side walls of the core board 200 are concave to form a groove 321 for the corresponding convex portion 311 to be inserted, and the matching arrangement of the groove 321 and the convex portion 311 can better realize the snap-on installation of the core board 200 in the wooden frame 100.

[0036] Combination Figure 3 As shown, in this embodiment, threaded holes 322 penetrating the grooves 321 are evenly distributed on the side and at the edge of the core plate 200, and the threaded holes 322 are threadedly connected with countersunk screws (not shown in the figure) penetrating the protrusions 311 to fix the core plate 200.

[0037] In this embodiment, the convex block 311 is fixed by passing the corresponding threaded hole 322 through the countersunk screw to fix the convex block 311 in the groove 321, so that the core board 200 is further fixed, and the core board 200 is fixed more firmly in the wooden frame 100;

[0038] When it is actually used, the wooden board 210 is also fixed to the corresponding side surface of the core board 200 by countersunk screws.

[0039] Combination Figure 4 As shown, in this embodiment, the side wall of the wooden frame 100 corresponding to the notch 201 protrudes outward to form a boss portion 323, and the side walls opposite to the notch 201 are provided with sliding grooves 324 along their width direction. The opposite sides of the U-shaped block 220 are provided with sliders 412 sliding in the sliding grooves 324, and the side walls of the U-shaped block 220 are provided with snap-in grooves 413 for the boss portion 323 to be snapped into, and the snap-in grooves 413 and the sliding grooves 324 are respectively provided with screws (not shown in the figure) that thread through the boss portion 323 and the slider 412.
